Overview of the RNO GSM applications

3 Overview of the RNO GSM applications

3.1 FAS

FAS is a tool intended to support frequency optimization in order to minimizeinterference in the radio network.

The interference level in GSM networks must be kept to a minimum in order touse the frequency spectrum in an efficient way, and to increase the capacity ofthe network. The speech quality and the amount of dropped calls are directlyaffected by the interference level.

FAS is an optional feature and aims at relieving the user from the burdenof frequency optimization. By monitoring the up- and downlink interferenceenvironment in the network, FAS can find bad frequency allocations, both forBCCH (Broadcast Control Channel) and Traffic Channel (TCH) carriers, andreplace them with better ones.

New FAS recordings are created and started in the RNO and recording resultsare collected by RNO. After the recording is completed, the result values arereported to OSS where they are processed and presented to the user in reportsand in geographical maps. The recording results can be uplink interferencedata, downlink Percentage Interfered Traffic (PIT) estimate and the ICDM.ICDM is a base for the PIT-estimate for a recording.

The ICDM is created during downlink recording and gives the interference effectof one cell on another. This matrix can be exported as a file in HTML-format ortab-separated format, for the purpose of major frequency replanning.

The frequency plan and the validity counters for a recording can also beexported. The result can also be exported to RNDBI if that application isinstalled.

The information from FAS can be used as a basis for the cell planningwhere FAS also supports updating of a planned area in Cellular NetworkAdministration (CNA) with frequency changes.

FAS helps the operator with the following:

• Find better frequency allocations in the cells (network optimization)

• Introducing a new cell in the network (cell planning)

• Monitor the interference levels on frequencies in use (network supervision)

The user can compare recording results and statistical reports produced, forexample, before and after a frequency reallocation.

The following functions are included in FAS:

7155 34-APR 901 0112 Uen D2 | 2010-05-10


• GNIP map presentations

• Frequency changes (reallocations)

FAS performs the following activities:

• Uplink recording

• Downlink recording

• Report presentation

• Export of results

• Import of ICDMs

RIR

A recording definition is sent to Radio Interference Recording (RIR) in theinvolved Base Station Controllers (BSC) when FAS activates an uplinkrecording. Recording results are retrieved from RIR at the end of a recordingperiod or when a recording is stopped.

8 155 34-APR 901 0112 Uen D2 | 2010-05-10


BAR

A recording definition is sent to BA-List Recording (BAR) in the involved BSCswhen FAS activates a downlink recording. Recording results are retrieved fromBAR at the end of a recording period or when a recording is stopped.

CNA

CNA is used to retrieve configuration data and information about the networksuch as cells, BSCs and channel-groups. FAS can export change orders to aplanned area in CNA.

CNAI

Cellular Network Administration Interface (CNAI) is used to export changeorders to update the network.

RNDBI

RNDBI can be used to export data to an open SQL Sybase relational database.

ENIQ

STS counters for Traffic Level and Speech Quality Index (SQI) are retrievedfrom Ericsson Network IQ (ENIQ) database for each recording period. TrafficLevel is used for validation and PIT estimation. The installation of ENIQ isoptional. If ENIQ is not installed, STS counters can be fetched from SDM (ifinstalled). If neither ENIQ nor SDM is installed, the user cannot get support withSQI or traffic level validation.

SDM

STS counters for Traffic Level and SQI are retrieved from Statistics Data Mart(SDM) database for each recording period. Traffic Level is used for validationand PIT estimation. The installation of SDM is optional. If ENIQ is installed,SDM will not be used. If neither SDM nor ENIQ is installed, the user cannot getsupport with SQI or traffic level validation.

BSM

The Base Station Management (BSM) database contains data about thenetwork (MOs and their attributes). If the FAS Spacing Matrix parameter isset to Combiner type, RNO fetches information about combiner type forcells from the database.

9155 34-APR 901 0112 Uen D2 | 2010-05-10


GNIP

Geographical and Logical Network Information Presentation (GNIP) can beconnected to FAS in order to present recording results and manage cell setsand frequency sets.

External Systems

Data is transferred between FAS and external systems using CNAI-file formator as files in tab-separated format.

User Categories

Typical users are cell planners and radio network optimizers.

3.1.2 Requirements

FAS software requirements within the computer system are the following:

• Telecom Security Services (TSS)

• CNA to get network information.

• CNAI

• ENIQ or SDM database to get network statistical information. (Optional)

• BSM to fetch the type of combiner used in the cell. (Optional)

• BRF installed.

The network elements have a configuration that transfers the recording files inthe BSCs to the OSS. This configuration is to be done when installing FAS.

The FAS application functions in the BSCs (RIR) must be enabled.

Note: BAR is a mandatory function in the BSC and therefore enabled bydefault.

3.2 FOX

FOX is built on FAS and uses the FAS measurements. In order to get a clearpicture of the measurements it is recommended to read about FAS as well.

FOX always uses both uplink and downlink measurements. Instead of justshowing the results like FAS, FOX has the additional functionality of proposingchanges that will improve the network quality. This is done with an algorithmthat takes all possible frequencies in all cells into account, and suggests thebest changes for the cells included in the recording.

10 155 34-APR 901 0112 Uen D2 | 2010-05-10


There are two levels of FOX recordings:

• Recommendation

• Automatic

In the Recommendation mode, FOX suggests a number of frequencyreallocations that are based on uplink and downlink recordings. The user canaccept or reject the suggestions before they are implemented.

In the Automatic mode, all suggested changes are implemented without userinteraction.

The interference measurements and the evaluation of data run repeatedlyaccording to the recording definition. During the time, the user will be notified bya change of status in the list when modification of the network is recommendedor is made.

The following functions are included in FOX:

• Recommendations on frequency reallocations

• Possibility to accept, change or reject the recommendations

• Automatic network update in accordance with the recommendations

• Evaluation of the network update

• Reallocation Log

• Generation of FOX-result (based on FAS-result)

A FOX recording results in one FOX result, one FAS result, and one ICDMresult.

3.2.1 FOX Relationship with other System Units

The relationships are the same as for FAS, see Section 3.1.1 on page 8.

3.2.2 Requirements

FOX requires that FAS is installed. Please read about FAS to get the full setof requirements.

3.3 SYROX

SYROX is an optional feature and requires that the FAS application is installedin order to work.

11155 34-APR 901 0112 Uen D2 | 2010-05-10


SYROX supports the operator in the planning of Frequency HoppingParameters (FHP) for groups of synchronized cells, by minimizing interference.The FHP that SYROX suggests on both cell and channel group level are thefollowing:

• Hopping Sequence Number (HSN)

• Frame Number Offset (FNOFFSET)

• Mobile Allocation Index Offset (MAIO) List

• Training Sequence Code (TSC)

SYROX can be deployed in networks using the BSS feature SynchronizedRadio Networks as well as in networks only using synchronization within sites,TG Synchronization feature. The ICDM measured in FAS is the cornerstone inSYROX and the quality of the ICDM directly effects the quality of the SYROXFHP recommendations.

The feature Flexible MAIO Management is needed to implement the FHPsettings proposed by SYROX in the network.

Channel groups that are synchronized and are optimized regarding their FHP,can be grouped into synchronization clusters. A synchronization cluster is agroup of cells that are synchronized, and where at least one channel group ineach cell is frequency hopping over the same frequency hopping set. Thereis support in SYROX for finding cells with channel groups that frequency hopover the same frequencies.

A SYROX recommendation can be generated for one or more synchronizationclusters at the same time. It is possible to specify number of plannedTransceivers (TRXs) for channel groups. The SYROX algorithm will insteadof using the existing number of TRXs for the channel group use the totalnumber of TRXs, that is the existing TRXs plus planned TRXs. It is alsopossible to influence the result of a recommendation by giving priorities tocertain cells, which will make the SYROX algorithm minimize the interferencebetween the prioritized interferers first. Furthermore, it is also possible to copyrecommendation settings from an already executed recommendation, changethe planned TRXs and priority setting values and substitute the used ICDM, tocreate yet another recommendation for the selected synchronization clusters.

The FHP recommendation can be examined in SYROX and all or a subset ofthe proposed changes of parameter values can be exported to a CNAI-file or toa planned area in CNA. The new FHP values can then be implemented in thenetwork from the planned area in CNA.

SYROX has the following main functions:

• Administration of synchronization clusters

• Generation of frequency hopping parameter recommendations

• Export of recommendations to CNAI files or CNA planned area

12 155 34-APR 901 0112 Uen D2 | 2010-05-10


The graphical user interface of SYROX is integrated with the RNO userinterface. This makes it easy to access the ICDM handling and ICDM reportwindows in FAS and to access the online help for both SYROX and FAS.

3.4 NCS

The handover decision in a radio network is based on measurements from themobile station on the downlink and from the base station on the uplink. Theaccuracy of the measurements is critical to making reliable handover decisions.If the number of neighboring cell relations is too high, measurement accuracydecreases. All the relations that can be good handover candidates need to beincluded in the active BA-List.

NCS is a tool that helps users to specify adequate neighboring cell relations foreach cell in the radio network. With NCS, handover decisions are more reliableand correct, which improves speech quality and results in fewer dropped calls.

The user can order NCS to perform recordings on cells handled by one OSS.After the recording is completed, the result values are reported to the OSS,where they can be processed and presented to the user in reports and in maps.The result can be exported into a tab-separated format or directly into theRNDBI database and the reports can be exported to various formats.

The information from NCS can be used as a basis for planning neighboring cellrelations. NCS also supports updating of a planned area in CNA with newneighboring cell relations and removals of neighboring cell relations.

In NCS, all data recorded according to the recording definition is accumulatedinto one result, which can be presented in reports and analyzed by the user.

NCS helps the operator with the following:

• Find neighboring cell relations to a new cell (network planning)

• Find missing neighboring cell relations in the active BA-List (networkoptimization)

13155 34-APR 901 0112 Uen D2 | 2010-05-10

3.7 TET

TET is used to estimate how much traffic a new cell will catch, and to quantifythe off-load and remaining traffic in the surrounding cells, that is, the cellsincluded in the cell set.

The feature is intended to facilitate capacity expansion; for instance, by hot-spotmicro-cells, since good coverage in the area is a prerequisite for the method.

The function of the tool is based on the measurement reports that an activemobile station sends to the BSC, approximately twice a second. These reportscontain information on measured signal strength, frequency and BSIC forthe six strongest neighboring cells. By setting out a test transmitter at a testsite and including its frequency in the active BA-lists of the surrounding cells,active mobile stations can report on the test transmitter as well as on ordinaryneighboring cells. These measurement reports indicate how many mobilestations receive a strong signal from the test transmitter, and how much trafficcan be carried by the cell if it existed.

The number of measurement reports that contains a record of the testtransmitter is extracted from BAR.

TET helps the operator with the following:

• Optimize the locations of new sites

• Estimate the pay-off ability of planned sites

• Dimension a cell

• Select suitable neighboring cells for the new cell

TET has the following functions:

• Generation of TET reports

18 155 34-APR 901 0112 Uen D2 | 2010-05-10


The relationship to other system units is shown in Figure 3.

Figure 3 TET Relationships

BAR

BAR-recording definitions are sent to associated BSCs when TET activates arecording. Recording results are retrieved from BAR at the end of a recordingperiod or when a recording is stopped.

For each cell and test frequency/BSIC combination, the following informationis required from BAR:

• The number of reports with Signal Strength higher than or equal to theserving cell plus a defined Relative Signal Strength Threshold.

• The number of reports with Signal Strength higher than or equal to thespecified Absolute Signal Strength Thresholds.

• The duration of time during which the test frequency was included in theActive BA-List.

CNA

TET fetches network information, such as cell names, from the CNA.

19155 34-APR 901 0112 Uen D2 | 2010-05-10


GNIP

The GNIP function can be connected to TET to manage cell sets.

External Systems

Data is transferred between TET and external systems such as files oftab-separated format.

User Categories

Typical users are frequency planners and cell planners.

The TET software requirements on the computer system are as follows:

• TSS to administer the authority in TET

• CNA is required to retrieve configuration data and information about thenetwork such as cells, BSCs, channel-groups

• BRF is installed.

• NCS is installed

The network elements must be configured to transfer the recording files in theBSCs to the OSS. This configuration is to be done when TET is installed.

3.8 CCE

CCE is developed to:

• Evaluate the coverage of radio access networks belonging to competitoroperators

• Compare strengths and weaknesses between own and competitor radioaccess networks

• Planning expansion of the radio access network coverage

• Make coverage comparisons without need for drive tests

The feature concept is to collect information about signal strength of cells notbelonging to the own radio access network and compare with the signal strengthof own cells. This is done by adding frequencies belonging to competitoroperators to the active BA list and letting the mobile stations measure the signalstrength of these competitor frequencies. The information received is used byCCE to calculate a relative total coverage of competitor cells in comparison with

20 155 34-APR 901 0112 Uen D2 | 2010-05-10


own cells. For more information, refer to Competitor Coverage Evaluation(CCE), User Description, Reference [6]. The results are presented per networkarea with a possibility to drill down to cell level.

Here are some of the measurements presented in the CCE reports:

• Average probability that a specified competitor has better coverage ina network area

• % of cells in a network area where a specified competitor is better

• % of recorded traffic in a network area where a specified competitor is better

The full content of each report will be explained later in this document.

CCE uses the recording function Competitor Coverage Recording (CCR) in theBSC to modify the BA list contents and to receive recording data.

3.8.1 Requirements

The following requirements apply:

• CCE requires that BRF is installed.

• CCE in OSS-RC requires that the optional BSS feature CCR is activated inthe BSC. CCR executes the collection of measurement data in the BSCand transfers the result as BA List recording printout files to OSS.

3.9 MRR

MRR is a tool for measuring radio characteristics. The measured radiocharacteristics are:

• Uplink and downlink signal strength (RXLEV)

• Uplink and downlink signal quality (RXQUAL)

• Uplink and downlink path loss

• Path loss difference

• Power level used by mobile station

• Power reduction used by base station

• Timing advance value used by mobile station

• Uplink and downlink frame erasure rate (FER)

The user can define statistical calculations on the measured radiocharacteristics. These calculated statistics are called radio statistics.

Overview of the RNO WCDMA applications

4 Overview of the RNO WCDMA applications

4.1 FFAX-W

FFAX-W can be used for remote pinpointing all non-optimal antennainstallations. The difference between two diversity branches must be small, butin case the difference is significant or the variation is larger than expected, thisis a strong indication that at least one of the antenna branches is not performingoptimally. The FFAX-W measurement is the signal level per branch andcomparing the difference in a cell makes it possible to detect swapped feedersor faulty feeder. The Radio Base Station (RBS) will provide the difference inSIR per branch as pdf counters. The user can specify a number of Cells or CellSets on which recordings can be performed. An FFAX-W recording is thendefined and scheduled. The recording results can be analyzed in a number ofpredefined reports. The reports present the difference in signal level per branchand shows if there is indication of a fault.

FFAX-W helps operators to :

• Identify all non-optimal antenna installations.

FFAX-W reports present the difference in signal level per branch and shows ifthere is indication of a fault.

4.1.1 FFAX-W Relationship with other system units

CS

FFAX-W fetches network configuration information from Configuration Service(CS).

PMS

FFAX-W uses Performance Management Subsystem (PMS) to initiatemeasurements towards a RNC/RBS. All FFAX-W activities are visible in thePMS GUI.

4.1.2 Requirements

The following requirements apply:

• FFAX-W requires that BRF is installed.

25155 34-APR 901 0112 Uen D2 | 2010-05-10


4.2 WMRR

WMRR helps operators with the following:

• Evaluate and supervise network performance and quality

• Perform network tuning and optimization

The feature concept is to collect statistics from User Equipment (UE),Radio Network Controller (RNC) and Radio Base Station (RBS). WMRRmeasurements can be performed for different Measurement Quantities andServices combinations.

For a description of the collected RNC Measurement Quantities and Servicescombinations, refer to Radio Environment Statistics, User Description,Reference [11] for a WCDMA system or Radio Environment Statistics, UserDescription, Reference [20] for a TD-SCDMA system.

The following RBS Measurement is collected in a WCDMA system:

• DL Tx Code Power per Spreading Factor (SF). (Downlink TransmittedCode Power). The transmitted power on one carrier and one channelizationcode in one timeslot.

Spreading Factor is a factor of two that determines the spreading code forthe channel. The range for each of the channels is 4-256. Valid valuesinclude 4, 8, 16, 32, 64, 128 and 256. The lower the spreading factor, thelarger the bandwidth and so fewer codes are available for other users.

This means that a high spreading factor corresponds to a low bit rateservice, for instance Speech, while a lower spreading factor corresponds tohigher bit rate services, such as Video.

The user can define statistical calculations on the measured radio statistics.

The following radio statistics are available for each combination of quantityand service:

• A threshold (tells the percentage of the measurement reports that fulfills thespecified threshold)

• Percentile

The WMRR application is a tool to initiate the WMRR recording function in thenetwork element, process the recorded information and present the data inreports.

WMRR has the following functions:

• Generation of WMRR reports

For more details about WMRR, refer to Radio Environment Statistics, UserDescription, Reference [11].

26 155 34-APR 901 0112 Uen D2 | 2010-05-10


4.2.1 WMRR Relationship with other system units

CS

WMRR fetches network configuration information from CS.

PMS

WMRR uses PMS to initiate measurements towards a RNC/RBS. All WMRRactivities are visible in the PMS GUI.

4.2.2 Requirements

WMRR requires that BRF is installed.

4.3 WNCS

The purpose of WNCS is to provide an easy and efficient way to keep theneighbor relations in the WCDMA Radio Network optimized. This means thatsupport is provided to find missing neighboring cells that must be defined asneighbors, and to find currently defined neighbor relations that can be removed.

WNCS is mainly used for:

• Trouble shooting: Missing neighboring cell relations can be detected.

• Supervision: The neighboring cell relations can be evaluated continuously.

• Planning areas with new cells: WNCS can be used to evaluate new cellrelations when new cells are added to the network. It is also possible tochange neighbor relations and cell priority.

The UE continuously monitors the radio environment. Not only defined neighborcells are measured, but also cells that are undefined neighbors can be detectedwith the background scanning process. The UE is configured to evaluate andsend measurement reports to the system only when certain events occur,such as when the measurement result for a cell fulfills certain criteria. Thisconcept is called event-triggered reporting. Events are collected by the GeneralPerformance Event Handling (GPEH) function in the RNC and sent on to PMSin the OSS, where they are included in a Result Output Period (ROP) file. Onefile is created for each RNC and Result Output Period. WNCS schedulesrecordings of GPEH events through PMS, collects the files, and processes theevents related to the measurements of surrounding WCDMA cells.

WNCS also collects and presents counters that measure the extent ofdefined WCDMA neighbor relations usage. The cell relation countersused by WNCS are pmRlAddAttemptsBestCellSpeech andpmRlAddSuccessBestCellSpeech. They are activated for all cells in theRNC through a Standard Statistics profile in PMS.

27155 34-APR 901 0112 Uen D2 | 2010-05-10


The results are presented in various reports.

WNCS has the following functions:

• Export of result data

• Generation of WNCS reports

For more details about WNCS, refer to Neighboring Cell Support WCDMARAN, User Description, Reference [12].

4.3.1 WNCS Relationship with other system units

CS

WNCS fetches network configuration information from CS.

PMS

WNCS uses PMS to initiate measurements towards an RNC. All WMRRactivities are visible in the PMS GUI.

4.3.2 Requirements

WNCS requires that BRF is installed. BRF is the common framework for allRNO applications.

4.4 GEO-W

The purpose of Geo-Observability for WCDMA (GEO-W) is to provide the userwith data provided by Geo-Observability Data (GEOD) based on periodic UEmeasurements and to create output files that contain events including variousdata and the geographical position of the subscriber that generated the datain the event. Thus, performance data in the network can be correlated togeographical position.

GEO-W is based on the RNO framework.

The functionalities included in GEO-W are the following:

• Activation and administration of the Geo-Observability measurements,including reports about the status of the result execution.

• Collection and processing of the data (including calculation of thegeographical position).

• Generation of an output file in zipped tab-separated format.

28 155 34-APR 901 0112 Uen D2 | 2010-05-10


The GEO-W positioning feature provides position data for terminals requestedto activate periodic measurement reports.

The GEO-W measurements consist of two parts: the RES which activates theperiodic measurements and the GPEH event which contains the measurementdata.

4.4.1 GEO-W Relationship with other system units

WMRR

Activating WMRR or GEO-W activates RES in RNC. The UE starts themeasurement and RNC creates the events and generates output files. Sinceonly one RES can be active in each RNC at any given time, it is impossible toschedule separate GEO-W and WMRR recordings that overlap in time. As anoption, it is possible to select GEO-W recordings to use RES measurementsscheduled by WMRR.

4.4.2 Functionality

GEO-W, which is the application of OSS and performs calculations on theGPEH events, requires that Geo-Observability Data (GEOD), the function ofRNC and activated by OSS, is available in the W-RAN network.

GEO-W functionalities are divided into the following four main parts:

Administration • Optional feature with a license with a dependencytoward the RAN feature GEOD. It shares the samelicense key with GEO-W. The license covers bothGEO-W and the access to the GPEH event createdin GEOD (the event is not accessible in PMS).

• The scheduling of recordings for GEO-W takinginto account the dependency between GEO-W andWMRR.

Post-processing • A production of the positioning algorithm based onGEOD.

• The generation of an output file containing thecalculated positions together with all the informationpresent in the original GPEH event.

• A summary report presenting information such asthe number of coordinates decoded or filenames.For more, see Section 6.4.3 on page 130

• One post-processing generates one output, thatis all the GPEH sub files created over time is notvisible to the user.

29155 34-APR 901 0112 Uen D2 | 2010-05-10


• The output file contains the GPEH positioning data,calculated coordinates and cause code.

Capacity • It is possible to have the feature active forup to 15000 cells at the same time, when nopost-processing is selected.

• It is possible to have the feature active for up to5000 cells at the same time, when post-processingis selected. For scenarios with a very high reportingfrequency (every 2 seconds) and high UE Fraction(100%) the limit is 1000 cells at the same time.

Accuracy and validity

• The GEO-W positioning feature provides positiondata for terminals that are requested to activateperiodic measurement reports. The positionaccuracy for an individual measurement reportvaries depending on the UE measurementaccuracy, the system cell layout, and the totalnumber of UEs that have periodic reports activated.The accuracy for individual measurement isexpected to be on cell level in a typical macro celllayout. By correlating position data from severalmeasurements from the same UE, the accuracycan be improved significantly.

• The accuracy for positioning event data depends onthe number of samples from the UE in the system.A high number of samples increases the confidencein the identifying position(s) for certain GPEH eventtypes (for example IRAT HO). With a large numberof samples, poor samples can be excluded from thedata set to further improve the accuracy. GEO-Wpositioning has introduced a field to indicate theaccuracy of the measured event.

Functions in the RNO GSM applications

5 Functions in the RNO GSM applications

This chapter describes the functions in the RNO GSM applications.

5.1 FAS

Below is a brief description of the FAS functions.

The user works with recordings and results in the RNO main window.

A new recording can be added to the list by defining it. The main parameters ina definition are the following:

• Recording Time - the time when the recording is to take place. The timeis divided into one or several recording periods.

• Cell Set - the cells involved in the recording.

• Frequency Set - the frequencies to measure on in an uplink recording, andto estimate PIT on in a downlink recording.

For downlink recordings, there are several options to select the BCCHfrequencies to be used. The user can for example use a frequency set oruse frequencies from the system parameter BCCHFreqNos passing somepredefined filter. For more information see the online help for the ICDM Settings.

The user can schedule a recording. When a recording is scheduled, FASactivates the recording periods.

For every completed recording period, FAS fetches the result and stores it in thedatabase and presents it in the Result Name column in the RNO main window.

The user can open reports from the RNO main window in order to get a detailedview of the radio network behavior.

The reports are used to find better frequencies which can replace the existingones. The user adds the changes to the Change Order. When all the requiredchanges are added, the user exports the Change Order to a planned area inCNA or to a CNAI-file.

The frequency allocation process in FAS is manual, but together with FOXmore automation is added. FOX is a complementary application.

By using FAS, it is also possible to create ICDM.

Presentation of the results can also be viewed on the GNIP map.

31155 34-APR 901 0112 Uen D2 | 2010-05-10


5.1.1 Defining Recordings

Defining a recording means that the user specifies parameters for a recordingand then saves it. If the recording is not scheduled when saved, the parametersmust not be completely filled in.

• Recording Name

The name can consist of up to 25 alphanumeric characters.

• Create New ICDM/Create FAS Result

The user can specify whether to record on uplink to get a FAS result, ondownlink to get an ICDM result or on both uplink and downlink

• PIT Estimates Settings

A definition of the way the traffic load is to be compensated during thePIT-estimation, and parameters for when the PIT-estimates are consideredas complete.

Compensation for lower interference from packet switched traffic than fromcircuit switched traffic is also available.

• ICDM Settings

A definition whether a new ICDM must be combined with an existingICDM or not, and in that case the way the ICDMs must be combined. Thefollowing alternatives are available:

� Use an existing ICDM (when no downlink recording is performed).

� Use the ICDM that is produced during the recording (when downlinkrecording is performed).

� Use a combination of a new ICDM (when downlink recording isperformed) and an existing in one of the following ways:

• The new ICDM complements the existing ICDM, by completingmissing information in the existing ICDM

• The existing ICDM complements the new ICDM where the newICDM does not have any information

• The two ICDMs are added to each other, using a relative trafficweight

� Specify whether the ICDM, that is measured during a downlinkrecording, is to be saved with a new name and a descriptive text or withthe same name as the recording.

If Multi Band Cell feature is activated in OSS:

� Multi Band Cell settings:

32 155 34-APR 901 0112 Uen D2 | 2010-05-10


• Specify whether all BCCH-frequencies are to be used as testfrequencies or only those selected by the cell set filter.

• Other band factors

• Percentile

The Percentile Value is given as a percentage valid for uplink measurement.The median interference is automatically recorded.

Normal percentile values are in the range of 70-95%.

• Relative Signal Strength Threshold C/I

This value is set in dB and determines the relative C/I (carrier tointerference) threshold for a neighboring cell when it is considered to causeco-channel interference in the measuring cell. This parameter must bedefined for downlink recordings. The values range from -63 to +63 dB.

• Relative Signal Strength Threshold C/A

This value is set in dB and determines the relative C/A (carrier to adjacentfrequency) threshold for when a neighbor cell is considered to causeadjacent-channel interference in the measuring cell. This parameter mustbe defined for downlink recordings. The values range from -63 to +63 dB.

• Number of Test Freqs. to Add at Each Interval

The maximum number of test frequency numbers that can be added to theactive BA-List at one time.

• BA List Change Interval (minutes)

How often the test frequency numbers in the active BA-List are to bechanged.

• Recording Time

When to start and when to stop.

A recording consists of up to four recording periods a day on selectedweekdays.

The ICDM result for one recording period is added to the previous recordingperiod.

The minimum required time for all selected test-frequencies to be recordedcan be calculated.

• Cell Set or Cells

The user selects a cell set (or cells) to record on. A cell set can contain asingle cell or several cells.

33155 34-APR 901 0112 Uen D2 | 2010-05-10


Note: The cells must belong to BSCs of the same version.

• Uplink Frequencies

For Uplink recordings the user specifies which frequencies to record on byselecting one of the following methods:

� Operator’s all available frequencies

� Configured frequencies for each cell

� Selected frequency sets

Note: If a frequency set is modified by another application or by otherFAS user, this affects FAS recordings using that set, until therecording is in progress.

• Comment

It is useful to state a descriptive text for a recording. It is possible to modifythis text during the life time of a recording, that is, also for a completedrecording. It is also possible to edit the Recording Comments field in theRNO main window.

• Automatic Result Export

The user can select to start an export of recording results automaticallyevery time a result is ready. It is possible to let the result be exported toRNDBI if that application is installed.

5.1.16 FAS ICDM Probable Interfering Cell Report

The FAS ICDM Probable Interfering Cell Report lists the names of the cellswith identic BSIC and BCCH combination, and FAS selects one of them to bethe probable interferer. The cells are selected among the recorded cell set andthose cells that are outside the cell set but within the user selected distancefrom the cell set, the so called bounding box. The most probable interferingcell is selected when the site position, the path loss, the antenna direction, andthe antenna gain are taken into consideration. The user can also compensatethe path loss if there are geographical circumstances that must be taken intoconsideration. The compensation factor can be stated in a text-file by the user.When a BCCH and a BSIC combination cannot be mapped to a cell name, cellname is shown as UNKNOWN/bcch_bsic, for example "UNKNOWN/123_07".

The FAS ICDM Probable Interfering Cell Report contains the following data:

In the header:

• ICDM name

• Creation date

• Path Loss per distance decade

• Sector antenna gain amplitude



• Sector antenna gain offset

• Path Loss Constant

• Creator



• BCCH

• BSIC

• Probable cell

5.1.17 FAS ICDM Probable Cell Name Diagnostics Report

This report gives a hint on what actions that are needed to make the probablecell name algorithm choices more accurate.

The report has three tables:

• Invalid Cell Data table

The table shows cells with missing and inconsistent configuration data suchas cell positions, antenna types and antenna directions.

• Unidentified BCCH/BSIC Combinations table

The table shows unidentified BCCH/BSIC combinations. The reason forbeing unidentified is probably that some cell data is invalid.

• Uncertain Choices table

The table gives a hint on the probable cell name choices that can be wrong.One reason is that the probable cell is so far away that it is not likelythat this is the correct cell. Another reason is that there are two or morecandidates that have similar predicted signal strength so that the choicecan be uncertain.

In the header:

• Recording name

5.1.18 Change Order

The user can manually change frequency allocations and then export thechanges to a CNAI-file or to a planned area.

50 155 34-APR 901 0112 Uen D2 | 2010-05-10


The Change Order contains information about the frequencies to delete andthe frequencies to add. The information includes the following data:

• Cell name

• Frequency number (one which replace the other on the same row)


• Percentile I

• Median I

• PIT

• PIT notes (PIT incomplete indication)

• Warnings if a frequency would cause a violation if it is taken in use in the cell

• Indication whether the frequency is included in a specific frequency setor not

5.1.19 Using GNIP Map Presentations

It is possible to present recording results on the GNIP map.

One of the following data from the FAS Overview Report can be presented percell on the GNIP map:

• Average interference levels

• Highest interference percentile

• Potential improvement in interference level

• Interference percentile on BCCH frequency

• PIT-value of the configured frequency with the highest PIT

One of the following data from the FAS Overview Comparison Report can bepresented on the GNIP map:

• Difference in average interference between the first and second recordings

• Difference in highest percentile values between the recordings

GNIP is able to mark co-frequency cells for a set of selected cells.

GNIP is able to mark adjacent frequency cells for a set of selected cells.

GNIP is able to mark cells using the same frequency as a selected frequency.

51155 34-APR 901 0112 Uen D2 | 2010-05-10


For a selected BCCH frequency, GNIP is able to present the BSIC allocationon that frequency by marking it on the GNIP map.

5.1.20 Handling Frequency Sets

Frequency set is a concept that specifies a set of frequency numbers. Thefrequency set has a name, a creator and a descriptive text. A frequency setcan be changed and deleted.

Frequency numbers can be added to a frequency set by:

• Choosing a frequency number from a list containing the operator’s fullrange of available frequencies

• Choosing existing frequency sets, or parts of existing frequency sets

• Importing configured frequency numbers for a given set of cells, from forexample CNA

GNIP can also be used to create frequency sets.

5.1.21 Proposing Frequency Changes in CNA

In FAS, after the user studies the FAS Cell Report, the user can proposebetter frequency allocations.

It is possible to mark one configured frequency and one test frequency in theFAS Cell Report in order to propose a replacement of the configured frequencywith the test frequency. This can be done for more than one pair of frequencies.

Replacing means that the new frequency takes the place of the old frequency ina channel group.

Frequency changes are collected in the FAS Change Order from where all theusers’ frequency changes can be reviewed.

When all required changes are added, the user can export the FAS ChangeOrder to a planned area in CNA or as a CNAI-file.

For a selected cell and BCCH frequency, the FAS application can give arecommendation for a BSIC allocation.

5.1.22 Handling Matrixes

There are two types of matrices that are possible to create, view, modify, andprint:

• Barring matrix

• Spacing matrix

52 155 34-APR 901 0112 Uen D2 | 2010-05-10


The barring matrix indicates one cell and lists those cells to which the indicatedcell cannot have the same frequencies allocated.

The spacing matrix defines the frequency spacing for frequencies allocatedto the same cell, to co-sited cells and to neighboring cells. The spacing canbe indicated either as an integer or combiner spacing, which means that thefrequencies allocated to the same cell must comply with the combiner spacingrequirements.

5.2 FOX

Below is a brief description of the FOX functions and a short description of theFOX Reallocation Search Algorithm.

In FOX Recommendation mode, FOX suggests frequency changes, which willbe implemented after the user approves them.

In FOX Automatic mode, suggested frequency changes are implementedautomatically.

All changes of the network configuration are logged in a Reallocation LogReport. In the reallocation log, it is possible to see how many changes areexecuted. It is also possible to select one evaluation period and open it tostudy it more closely.

5.2.1 FOX Reallocation Search Algorithm

The purpose of the reallocation search algorithm is to make frequencyreallocation suggestions. The input to the reallocation search activity is theuplink recording result and the estimated PIT (Percentage Interfered Traffic).The output is the Change Order Recommendation and/or the Change OrderEvaluation Report. The uplink recording result is interference data for allpossible frequencies (allocated as well as non allocated) in all cells in therecording cell set. The downlink recording results are estimated PIT for thesame frequencies and cells.

The algorithm runs in two phases: The preoptimization phase and the normalphase.

During the pre-optimization phase only the cells fulfilling any of the requirementsspecified in the Reallocation Search Settings window, Pre-Optimizationpanel, is considered. The FOX algorithm will in that way give priority to cells witha bad overall performance. Only one frequency change per cell is suggested.

During the normal phase all cells in the reallocation cell set is considered. Morethan one frequency change per cell can be suggested.

The reallocations search makes a list of all possible frequency changes (withinthe reallocation cell set) according to the following principles:

53155 34-APR 901 0112 Uen D2 | 2010-05-10


• To improve the cell’s own uplink

• To improve the cell’s own downlink

• To remove a downlink interferer (enough downlink improvement in anothercell and new frequency acceptable in measured cell)

Parameters for required improvement and acceptable impairment can be setfor complete and incomplete PIT-estimates, respectively. See Section 5.2.2on page 55 .

A reallocation suggestion corresponds to a field in Figure 6.

Next step is to go through the following tests (see Figure 6):

1. Uplink data reliability test: Keep the frequency change only if it has enoughuplink samples.

2. Same frequency set check: Keep the frequency change only if theallocation and the candidate frequency are part of the same frequency set.

3. Halted (non-active) cells: Keep the frequency change only if the cells thatcan cause interference are active during the recording.

4. Prioritize remaining frequency changes according to highest interferenceimprovement, highest downlink PIT improvement, improvement of worstuplink interference or improvement of worst downlink PIT. See also Section5.2.2 on page 55.

Figure 6 First part of FOX Reallocation Search

The result is a list of proposals (in prioritized order).

Then reallocation search starts from the top of the prioritized list and iteratesstep 1 to 4 below to compile the recommendation list (see Figure 7).

54 155 34-APR 901 0112 Uen D2 | 2010-05-10


Figure 7 Second part of FOX Reallocation Search

1. The reallocation search removes the change if it does not lead to an overallPIT-reduction.

2. Changes not compliant with Barring Matrix or Spacing Matrix are removed.

3. Changes to or from the same (or adjacent) frequency twice during onereallocation search in the same area are not allowed and for that reasonremoved.

4. If the change was allowed, all PIT-values are recalculated and thereallocation search algorithm continues with the next frequency in the list.

When there are no more frequency changes in the list, the recommendationis ready.


FOX needs the same definitions as FAS and the following FOX definitions:

• State whether the recording is a recommendation type or an automatic type

• Specify parameters for the FOX algorithm (Reallocation Search Settings)

• Define the evaluation period

The user can set the following parameters for the uplink interference:

• Minimum Required Uplink Interference Improvement

• Maximum Accepted Downlink PIT Impairment

The user can set the following parameters for the uplink interference whendownlink PIT estimate is incomplete:

55155 34-APR 901 0112 Uen D2 | 2010-05-10


• Minimum Required Uplink Interference Improvement

• Maximum Accepted Downlink PIT

The user can set the following parameters for the downlink PIT improvement:

• Minimum Required Downlink PIT Improvement

• Maximum Accepted Uplink Interference Impairment

The user can select how to prioritize among the proposed frequency changes:

• Prioritize highest uplink interference improvement

• Prioritize improvement of worst uplink interference

• Prioritize highest downlink PIT improvement

• Prioritize improvement of worst downlink PIT

The user can select a set of cells where reallocations are allowed (thereallocation cell set).

It can also be specified that only BCCH frequencies (broadcast controlchannels), only TCH frequencies or all frequencies must be included in thereallocation search.

The user can set the following system parameters regarding the number ofrequired samples for a measurement to be reliable:

• Minimum Number of Uplink Samples. Normally there is onesample/frequency every 15th second for each TRX (transceiver) on theuplink.

• Minimum Number of Downlink Samples. Normally there are twosamples/second in measurement reports per active MS (mobile station) inthe cell.

It is possible for FOX to give priority to cells with a bad overall performancein the pre-optimization phase. Three independent criteria can be set by theuser, all cells fulfilling at least one of the conditions below will be part of thepre-optimization phase:

• GPRS cells DL: Minimum percentage GPRS CS1–4 traffic with low bitrateand minimum GPRS CS1–4 traffic.

• EGPRS cells DL: Minimum percentage EGPRS traffic with low bitrate andminimum EGPRS traffic.

• CS cells UL: Minimum percentage CS traffic with SQI UL (Speech QualityIndex) Bad and minimum average occupied CS timeslots.

• CS cells DL: Minimum percentage CS traffic with SQI DL (Speech QualityIndex) Bad and minimum average occupied CS timeslots.

56 155 34-APR 901 0112 Uen D2 | 2010-05-10


5.2.3 Generate FOX Result from a FAS result

A FOX result can be generated from an already existing FAS result. The usermust specify how the estimation of PIT is to be done, which ICDM to use, and tospecify the reallocation search settings, according to Section 5.2.2 on page 55.

This is an easy way to see the effect of different parameters settings in the FOXalgorithm without starting a new recording.


In FOX the following reports can be opened:

• Change Order Recommendation

• Change Order Evaluation


• All FAS-reports

The FOX report hierarchy is shown in figure Figure 8 below.

Figure 8 The Report Hierarchy for FOX Reports

5.2.5 Change Order Recommendation

The user can accept or reject the frequency reallocation recommendations inthe Change Order Recommendation. It is possible to modify the frequencyreallocation recommendations before accepting them. When a ChangeOrder Recommendation is accepted, the accepted reallocations are sent toa Planned Area.

57155 34-APR 901 0112 Uen D2 | 2010-05-10


In the header:

• Result name


• Evaluation period

• ICDM name


• Name of the reallocation cell set


• Frequency set

• Creator

Per cell:

• Change

5.2.6 Change Order Evaluation

Change Order Evaluation is used to get information about approvedreallocations. The Change Order Evaluation contains the same columns as

58 155 34-APR 901 0112 Uen D2 | 2010-05-10


the Change Order Recommendation plus an additional column, Executed,which indicates the changes of frequencies that are implemented in thenetwork. The date when the Change Order was applied is stated in theheader. The Change Order Evaluation is generated when the user acceptsthe recommended changes or when a FOX Automatic recording is executed.

5.2.7 Reallocation Log

A FOX Change Order Evaluation Report can be opened from theReallocation Log on a specific evaluation period.

In the header:

• Recording name

• The date when the recording was performed

• ICDM name


• Reallocation cell set name


• Frequency set

• Creator

Per Evaluation Period:

• Evaluation date and time

• Date and time when the reallocation was applied to the network

• Number of BCCH frequency reallocations

• Number of TCH frequency reallocations

5.2.8 Handling Reallocation Suggestion

In FOX, recommendation type, the user can change the recommendedreallocation suggestion in the following ways:

• Mark a recommended Reallocation Suggestion as discarded

• Change the suggested BSIC

Any frequency reallocation suggestions in the list implies that all the previousfrequency reallocations are implemented as well.

59155 34-APR 901 0112 Uen D2 | 2010-05-10


The Change Order Recommendation is carried out when the user accepts theChange Order, with or without modifications, at the time for network update.

After the Change Order Recommendation is executed, the Change OrderEvaluation and the Reallocation Log are used to get information aboutimplemented reallocations.

5.3 SYROX

This chapter describes the SYROX functions.

5.3.1 Starting SYROX

From the RNO Main Window it is possible to do the following:

• Open the SYROX Synchronization Clusters Window

• Open the Generate Result Window.

• Open the Recommendation report. This report can be opened when aFAS ICDM result or an existing SYROX recommendation result is selected.

5.3.2 Administration of Synchronization Clusters

A synchronization cluster is a set of channel groups which all use the samefrequencies. To make use of a cluster, it is important that the channel groupsutilize synthesized frequency hopping and are synchronized with each other.

It is also possible to create synchronization clusters consisting of channelgroups which all use the same frequencies, but are only synchronizedwithin each individual site. If this site-synchronization property is set for asynchronization cluster, it will be transformed into one synchronization clusterper site when it is used by the SYROX algorithm.

A synchronization cluster is characterized by the following properties:

• Name of the synchronization cluster

• HFS (Hopping Frequency Set)

• A list of channel groups

• A selection indicating whether the synchronization cluster is regarded asone cluster per site or not

SYROX supports the creation of synchronization clusters by filtering outhopping channel groups which all use a specified HFS.

60 155 34-APR 901 0112 Uen D2 | 2010-05-10


The user also has the possibility to edit or delete existing synchronizationclusters. The synchronization clusters are stored in a database and can beshared among all users of SYROX.

Each time a synchronization cluster is edited, SYROX will check if the includedchannel groups still exist and still use the defined HFS. New channel groupsusing the HFS can be added when the synchronization cluster is edited.

5.3.3 Generating a Recommendation

A recommendation can be generated for one or more synchronization clusters.

The following data is input to the generation of a SYROX recommendation:

• Name of the recommendation result

• One or more synchronization clusters

• An ICDM

• A list of channel groups, each having a number of planned TRXs to beconsidered in the algorithm. This list is optional and can be empty.

• A list of cells, each having a number of prioritized interferers to beconsidered in the algorithm. This list is optional and can be empty.

For each generation of SYROX results the following conditions must be fulfilled:

• The cell (and its channel groups) can only be included in onesynchronization cluster. This means that only one frequency hopping setper cell can be optimized by SYROX

• All cell and channel group data that are needed for the SYROX algorithm tocalculate the recommendation, must exist in CNA and BSM. The followinginformation is needed:

� Number of TRXs per channel group (CNA, or BSM if exists)

� Site name (CNA)

� Subcell to which the channel group belongs (CNA)

� BSC version to which the channel group belongs (CNA)

There are additional consistency checks performed when a generation isstarted. A check is done to ensure that all channel groups in the synchronizationcluster still exist and that all channel groups in the synchronization cluster stilluse the same HFS as the one defined for the synchronization cluster.

The parameters that was input to an earlier SYROX recommendation can beused as a template for creating a new recommendation.

61155 34-APR 901 0112 Uen D2 | 2010-05-10


5.3.4 SYROX Algorithm

The SYROX algorithm works according to the following:

1. Assignment of HSN values.

All channel groups in the same synchronization cluster will be assigned thesame HSN. Different synchronization clusters in one recommendation willbe assigned different HSN values to as large extent as possible.

2. Creation of MAIO clusters and assignment of FNOFFSET values.

For each of the synchronization clusters, the algorithm will use informationfrom the ICDM. The algorithm considers the number of TRXs used byeach channel group plus the number of planned TRXs for channel groupsthat are included in the optional list of planned TRXs. The algorithm alsouses the optional list of prioritized cells, were each cell has a number ofprioritized interferers. If the ICDM does not contain the information then theco-sited cells will be clustered together. This information is used to groupthe channel groups which interfere strongly with each other together intoMAIO clusters.

All MAIO clusters will be assigned different FNOFFSET values (if possible)to use for the cells (the cell to which the channel group in the MAIO clusterbelongs). This value is dependent on the interference between the MAIOclusters.

3. Assignment of MAIO values.

Each channel group in a MAIO cluster will be assigned a MAIO list withunique MAIO values within the MAIO cluster. The number of values in theMAIO list is equal to the number of TRXs used by the channel group plusthe given number of planned TRXs.

4. Assignment of TSC values.

TSC is assigned on MAIO cluster level on the same principles as theFNOFFSET assignment, but with the addition that interference betweensynchronization clusters is also taken into account. All channel groups inthe same MAIO cluster will be assigned the same TSC. However, it is verylikely that the same TSC value will be repeated for several MAIO clusterssince there only are 8 possible TSC values.

Channel group number 0 will never be assigned a new TSC value bySYROX since this value is defined by the BCC part of the BSIC for the cell.

The result of the SYROX algorithm will be a list of recommended settings forthe parameters HSN, FNOFFSET, MAIO and TSC.

62 155 34-APR 901 0112 Uen D2 | 2010-05-10


5.3.5 Viewing a Recommendation

It is possible to open a recommendation report in SYROX to view the FHPrecommendations (and the settings used when the recommendation wasgenerated) for all channel groups included in a recommendation. The channelgroups are grouped into synchronization clusters and MAIO clusters in thereport.

5.3.6 Exporting a Recommendation to CNAI-files and CNA

SYROX recommendations for parameter settings can be exported to a CNAI-fileor a CNA planned area. This provides an easy way to update the parametersin the affected BSCs.

In the Recommendation Report, it is possible to individually select the MAIOclusters for which the recommended parameters are exported.

For each MAIO cluster that is to be exported, there is also an option to choosewhether to include TSC parameter recommendation or not.

5.4 NCS

This chapter describes the NCS functions.


The following parameters are available:

• Recording name

• Multi Band Cell Offset (if Multi Band Cells are used in the network)

• A relative signal strength threshold

• An absolute signal strength threshold

• The number of test frequency numbers that can be added to the activeBA-List at one time

The Probable Neighboring Cell Report shows all surrounding cells thatare candidates for neighboring cell, which means that the cell is consideredas probable for handover from the serving cell. When a BCCH and a BSICcombination cannot be mapped to a cell name, cell name is shown asUNKNOWN/bcch_bsic, for example UNKNOWN/123_07.

The Probable Neighboring Cell Report contains the following data:

In the header:

• Recording name

5.4.9 Change Order

The Change Order is used for adding cells to an order which can be sentto a planned area in CNA or as CNAI-file. See Section 5.6.8 on page 89 forinformation on proposing changes to cell relations in CNA. The Change Ordercontains the following data:

A table with Neighboring Cell Relations to Add:

• The BSC and the name of the cell


• BSIC

• Cell name (neighboring cell)

• Number of measurements reports

• Number of reports above relative signal strength threshold

• Number of reports ranked as number one

• Average signal strength when ranked as number one

A table with Neighboring Cell Relations to Remove:

• The BSC and name of the cell


• BSIC


• Number of handover attempts

• Relative usage

• Success rate

• Percentage of handover attempts that were reversed

• Percentage of handover attempts that failed

• Mutual or single removal

5.4.10 Proposing Changes to Neighboring Cell Relations in CNA

In the Cell Report, it is possible to mark undefined neighbors and get mutualneighboring cell relations between the cell for which the report is presented andthe marked undefined neighboring cells added in a Change Order. Definedneighbors can be marked for removal.

73155 34-APR 901 0112 Uen D2 | 2010-05-10


Neighboring cell relations to add and to remove are collected in a ChangeOrder where they can be reviewed.

When all cell relations to add and to remove are collected, the user can exportthe NCS Change Order to a planned area in CNA or as a CNAI-file. TheChange Order in GNIP is separated from the NCS Change Order.

In the list of neighboring cell relations it is possible to add neighboring cells toan NCS Change Order by selecting them in a GNIP map. It is also possibleto update the planned area in CNA, through CNAI, with new neighboring cellrelations from the GNIP map.

Note: Neighboring cell relations are always added mutual. For removals, theuser can select if the relation is to be removed mutual or single.


It is possible to present recording results on the GNIP map. The data isdisplayed when appropriate cells on the GNIP map are selected.

One of the following data from the Overview Report is presented per cellon the GNIP map:

• The least number of times (relative to the total number of reports) for anyfrequency number and BSIC combination of defined neighbors reportedabove the relative signal strength threshold

• The highest number of times (relative to the total number of reports whilethe test frequency number was in the active BA-List) for any frequencynumber and BSIC combination reported above the relative signal strengththreshold.

The following data for a selected frequency number and BSIC combination inthe Cell Report can be presented on the GNIP map:

• The number of times (relative to the total number of measurement reportswhile the frequency number was in the active BA-List) the frequencynumber and BSIC combination was reported above the relative signalstrength threshold

• Number of reports (relative the total number of measurement reports) withranking number 1

• STS counter: Number of handover attempts

• STS counter: Number of successful handovers

• STS counter: Number of handover reversions

• STS counter: Number of handover failures

The GNIP map can present the BSIC allocation for any selected BCCHfrequency number.

74 155 34-APR 901 0112 Uen D2 | 2010-05-10


Using one of the following methods, the GNIP map can also be used to createfrequency sets:

• Add test frequency numbers by selecting cells

• Add test frequency numbers by selecting cells within a given geographicalarea

5.5 NOX

In NOX Recommendation recordings, NOX suggests neighboring cell relationsto be added or removed based on the NOX Reallocation Algorithm. The resultsare presented in a Change Order Recommendation, in which the user mustapprove or reject the suggested changes. A Change Order Evaluation isgenerated after the Change Order Recommendation is approved.

When NOX Automatic recordings are used, the change order is sent directly toa planned area in CNA without user interaction. The time for network update isdecided in configuration. A Change Order Evaluation is generated after thechange is implemented in the network.

If neither the ENIQ, nor the SDM database is installed, NOX cannot supportremovals of neighboring cell relations.

5.5.1 Reallocation Algorithm

In NOX Automatic and NOX Recommendation recordings, NOX uses areallocation algorithm to add or remove neighboring cells. The algorithmparameters are found in the parameter database. The input to the reallocationalgorithm consists of:

• Data from BAR-recording in the BSCs (for further information, read aboutNCS)

• Handover statistics (handover attempts, successful handovers, handoverfailures and handover reversions)

• Network data

• Parameters of the reallocation algorithm, see below

• Barring Matrix, see Section 5.5.2 on page 77.

• The contents of the file /var/opt/ericsson/nox/data/db/nox.pingpong. This file consists of relations that are added by NOX. If NOXwants to add a previously added relation again (called a "ping-pong add"),the relation will not be added since the relation obviously was consideredinadequate and removed. Adding it again will probably lead to it beingremoved again, and so on.

75155 34-APR 901 0112 Uen D2 | 2010-05-10


The reallocation algorithm will only run for cells for which sufficient data isavailable. For example, when data on the total number of measurementreports and total number of outgoing handover attempts logged exceeds thecorresponding thresholds. The number of measurement reports indicates ifthere is sufficient traffic, and the number of outgoing handover attempts blocksremoval of neighboring cell relations from a new cell.

The user can set the following parameters for the Reallocation Algorithm:

• Minimum length of long BA-list

• Minimum number of reserved spots for dual band in BA-list

The following parameters affect additions:

• Minimum number of measurement reports

• Minimum fraction of measurement reports ranked as number 1

• Minimum fraction of reports stronger than serving cell:

� Short BA-list

� Long BA-list

� Short BA-list, dual band

� Long BA-list, dual band

� Disallowed Hierarchical Cell Structure (HCS) layer combinations forneighbor cell relations

The following parameters affect removals:

• Minimum number of handover attempts from the originating cell

• Maximum number of handover attempts on the relation for the following:

� Short BA-list

� Long BA-list

� Short BA-list, dual band

� Long BA-list, dual band

• Minimum handover success rate on the relation

• Required relative handover usage on the relation

The parameters are valid for all NOX recordings.

After the Reallocation Algorithm is run, the user will be notified by a change ofstatus in the list when modification of the network is recommended or is made.

76 155 34-APR 901 0112 Uen D2 | 2010-05-10


5.5.2 Barring Matrix

The user can specify which neighboring relations that must or must not bedefined in the network by means of the Barring Matrix. The Barring Matrixconsists of two lists. One list contains neighboring cell relations that must notbe removed. The other list contains relations that must not be added.

The Reallocation Algorithm does not affect relations stated in the Barring Matrix.

5.5.3 Configuration Change

The user can set a time when NOX, through CNA, is to implement themodifications of the neighboring cell relations in the network. Normally themodifications are done every 24 hours.

5.5.4 Definition Recordings

In addition to an NCS definition, the user can state the following for the NOXrecording:

• The recording can be performed in Automatic or in Recommendation mode

• Algorithm options:

� In Automatic mode: Allowed changes; additions, removals or singlerelation removals in mutual relations

� In Recommendation mode: To mark proposed changes in ChangeOrder


5.5.5 Generation of NOX Result from a NCS result

A NOX-result can be generated from an already existing NCS-result. This is aneasy way to see the effect of different parameters settings in the NOX-algorithmwithout starting a new recording.


In NOX the following reports can be opened:

• Change Order Recommendation

• Change Order Evaluation


• All NCS-reports

77155 34-APR 901 0112 Uen D2 | 2010-05-10


The Report Hierarchy is shown in Figure 10.

Figure 10 The Report Hierarchy for NOX Reports

5.5.7 Change Order Recommendation

The Change Order Recommendation is based on the result from a NOXRecommendation recording. It is possible to modify the suggestions in the NOXChange Order Recommendation. The Change Order Recommendation canthen be exported to a CNAI-file or to a Planned Area in CNA.

5.6.8 Proposing Changes to Neighboring Cell Relations in CNA

In the Cell Report, it is possible to select undefined neighbors and getneighboring cell relations between the GSM cell for which the report ispresented and the selected undefined neighboring WCDMA cell added in aChange Order. Defined neighbors can be selected for removal.

Neighboring cell relations to add and to remove are collected in a ChangeOrder where they can be reviewed.

When all cell relations to add and to remove are collected, you can export theGWNCS Change Order to a planned area in CNA or as a CNAI-file.

5.6.9 Administration of UMFI Sets

A UMFI set is a collection of UMFIs on which a GWNCS recording can beperformed.

The UMFI set has a name, a creator and a descriptive text.

A UMFI set can be changed and deleted.

UMFIs can be added to a UMFI set by:

• Choosing a frequency number (MFDDARFCN) from a list containing theoperator’s full range of available frequencies, choosing a scrambling codeand selecting a diversity

• Choosing existing UMFI sets, or parts of existing UMFI sets

• Choosing a set of GSM cells and a distance and then fetching the UMFIs ofWCDMA cells that are close enough to the GSM cells

• The BSICs from which to extract data for each test frequency.

The user can specify the days and hours for which the traffic estimationrecordings are to be made and choose between having recordings executed onstart date only, or to have them repeated on a daily basis.

Combinations of the BCCH, BSIC, and the test transmitter output powerare defined in the Test Frequencies dialog box in order to identify the testtransmitter. There is one combination of BCCH and BSIC per test transmitter.

Comments on antenna type and height, and on the location of the testtransmitter can also be input. These comments can be changed on site.


TET can handle the following reports:

• Overview Report

• Traffic Level Chart of Surrounding Cells

• Traffic Level and Off-load Report

5.7.3 TET Reports

The user can set and use default settings for the reports. The settings areuser-specific and include threshold values, sorting criteria, and parameter units.

The RNO main window is the starting point for handling reports. A TET resultmust be selected in the list before a report can be displayed.

• Estimated off-load based on relative signal strength threshold (% of existingtraffic level).

• Remaining traffic level based on absolute signal strength threshold (erlang).

• Remaining traffic level based on relative signal strength threshold (erlang).

The report can be sorted on any column in ascending or descending order.

It can be useful to set a threshold value for data that is to be presented in thereport. Threshold values can be set on any data column, but only one at a time.The threshold values can be saved for use as default.

The final row of the list shows the total (sum or average) of each column. Therow is not influenced when the report is filtered, since it always shows valuesfor the whole recording. The total row shows the average for the two columnsEstimated Off-Load Absolute SS Threshold and Estimated Off-loadRelative SS Threshold and the sum for all other columns.

By selecting one or several cells from the list, the results can be displayed inthe following reports:

92 155 34-APR 901 0112 Uen D2 | 2010-05-10


• Traffic Level and Off-load Report

It is easy to duplicate the chart. That way, the user can simultaneously viewresults from several recording periods.

5.7.7 Calculations of Erlang in the Reports

The formula for calculating erlang in the Traffic Level and Off-load, is asfollows:

E = # reports * 0.48/3600 * h

E Erlang

# reports One of the following:

• Total number or measurement reports in the cell

• Number of measurement reports above absolutesignal strength threshold containing the BCCH-BSICcombination

• Number of measurement reports above relativesignal strength threshold containing the BCCH-BSICcombination.

0.48 The reporting interval in seconds

h Time for the recording period in hours, which is one ofthe following:

• Total recording time for the recording

• The time during which the BCCH frequency was inthe active BA-list.

5.8 CCE

The RNO main window has the following CCE related functions:

• Defining new CCE Recordings (Section 5.8.1 on page 96)

• Presenting CCE Reports (Section 5.8.2 on page 98)

• Managing the List of Recordings and Results

• Handling Cell Sets

• Handling Competitors (Section 5.8.7 on page 102)

• Presenting Online Help

• Presenting Errors

95155 34-APR 901 0112 Uen D2 | 2010-05-10



A CCE recording is defined from the new recording menu item in the RNOmain window. In the CCE New Recording Window the user must supply allparameters that are needed to start a CCE recording.

The following parameters must be specified when defining a CCE recording:

• Recording name

The name of the recording. The result created by this recording will havethe same name.

• BA List Change Interval

The active BA-list has a limited number of positions available for competitorfrequencies. Since the number of competitor frequencies defined in a CCErecording usually is greater than the available positions in the BA-list, allcompetitor frequencies cannot be added simultaneously. The BA ListChange Interval parameter defines the time in minutes that each group ofcompetitor frequencies are present in the active BA-list before they arereplaced by a new group of competitor frequencies.

• Number of Test Frequencies to Add at Each Interval

The number of test frequencies that can be added to the active BA-Listat one time. This value is used to limit the total amount of frequenciesin the active BA-List.

• Temporary Number of Multi Band Cells Reported

Temporary setting of Multi Band Cells Reported (MBCR) parameter inthe BSC used during the recording. This parameter temporarily replacesthe parameter MBCR for all cells in the recording during the time of therecording. After the recording is finished the original value of parameterMBCR is restored.

The value defines the number of neighboring cells from GSM frequencybands other than the one used by the serving cell that must be includedin the measurement reports. The option Network Settings means that theexisting settings in the network is used. When running a CCE recording itcan be advisable to change the value depending on which frequency bandsthe competitor frequencies belong to.

Note: Changing the value can affect handover performance since therecan be fewer handover candidates to chose from.

• Number of WCDMA Cells in Each Measurement Report

Temporary setting of FDDMRR parameter in the BSC used during therecording. This parameter temporarily replaces the parameter FDDMRR forall cells in the recording during the time of the recording. After the recordingis finished the original value of parameter FDDMRR is restored.

96 155 34-APR 901 0112 Uen D2 | 2010-05-10


The value defines how many measured neighboring UTRAN cells thatmust be included in measurement reports. The remaining positions inmeasurement reports will be used for reporting GSM cells according to theparameter MBCR. If there are still remaining positions, these are used toreport next best valid cells in other radio access technologies. The optionNetwork Settings means that the existing settings in the network is used.When running a CCE recording it can be advisable to decrease the valuein order to make more positions in the measurement report available forGSM frequencies.

Note: Changing the value can affect handover performance since therecan be fewer handover candidates to chose from.

• Minimum Threshold for Sufficiently Measured (measurement reports)

This is the minimum number of measurement reports containing aBCCH/BSIC combination needed in order for the frequency to beconsidered as sufficiently measured. Only sufficiently measuredfrequencies are included in calculations of competitor coverage in theoverview and cell set reports.

• Recording Time

A CCE recording consist of one or more consecutive recording periods.The time for each recording period can be individually set.

It is possible to create a recording that is repeated daily or on selecteddays of the week.

• Cell Sets

One or several cell sets defining the network area that must be measuredand included in the CCE result. The cell sets can be overlapping and in thatcase CCE will use the union of cells. For example it is possible to definethe whole network as one network area and in the same recording havesub-areas with smaller parts of the network. Cell sets can be created andedited in the Cell Set GUI.

• Competitors

One or several competitors that must be measured and included in theCCE result. Each competitor is defined by its frequencies and NetworkColor Codes (NCCs). In a CCE recording, a frequency/NCC combinationmust be unique to one competitor. Competitors can be created and editedin the CCE Competitors GUI.

The maximum number of competitors in a CCE recording is 10.

97155 34-APR 901 0112 Uen D2 | 2010-05-10


Note: If a competitor definition is modified, this affects active CCErecordings using that competitor, from the first recording period thatstarts after the change of the competitor. A warning message isissued when a competitor used in a active or scheduled recordingis modified.

If the defined recording is scheduled, CCE will initiate the measurementswhen the time for a recording period arrives. When the first recording periodin a recording is finished, a CCE Result will be created and displayed in theRNO main window. The name of the result will be the same as the name ofthe recording. Measurement data from the following recording periods in therecording will be aggregated in the same CCE result when each recordingperiod is completed.

If the recording is not scheduled but only saved, all information entered by theuser will be saved in the recording definition. The recording definition can becomplemented or changed at a later time. No measurements will be initiateduntil the user chooses to schedule the saved recording.

An existing recording definition can be used as a template when a newrecording is defined.

The following is a short presentation of the information that must be suppliedwhen defining a CCE recording. For a more detailed presentation, refer toCompetitor Coverage Evaluation (CCE), User Description, Reference [6] andthe online help.

5.8.2 Presenting CCE Reports

For a CCE result it is possible to open the following reports:

5.10.3 Deletion of Recording Results in the Database

A script to delete data from the SQL database is included in the product. Thedatabase size needed for recording results can be quite big, so this script mustbe run on a regular basis. The script deletes all recording results older than aspecified number of days. It is possible to specify the type of results to delete,for example that only FAS results are deleted. It is also possible to specify thatall results regardless of type are deleted.

5.10.4 Using Business Objects Universe and Reports in RNDBI

Along with the RNDBI product a Business Objects Universe is delivered. Thisuniverse is mapped on the database structure of RNDBI. Four example reportsare also delivered to show what possibilities there are to make reports.

5.10.4.1 RNDBI Universe

All tables and columns in the RNDBI database are available as universeclasses and objects ready for use in reports. Additional objects and predefinedtable joins are also included to suit the needs of the example reports. Thoseobjects and joins will probably also be possible to use as a template when newcustomized user defined reports are created. If the universe does not suit theneeds for this purpose it is always possible to copy the existing universe to anew universe and then create and modify objects and joins.

Changing and viewing a universe is done in the Designer product, whichis a part of the Business Objects product family. For more informationabout Business Object, refer to Ericsson Business Intelligence Deployment,Reference [9].

5.10.4.2 RNDBI Example Reports

The following example reports are provided:

6.3 WNCS

This chapter describes the WNCS functions.


In the recording definition, the following items are specified:

• A recording name

• Data to measure

• A time schedule for the recording

• A set of cells to be included in the recording. The cells in the cell set canbelong to more than one RNC.

Data to measure specifies the source to collect data from. Both GPEH eventsand Counters, only GPEH events or only Counters.

The time schedule determines the days of the week the recording will beexecuted and the number of times the time schedule is repeated. Each periodof data collection and active recording is called recording period. Up to fourrecording periods can be specified.

WNCS will setup collection and regularly collect data from the network elementsduring recording periods. The data is collected periodically every 15 minutesfor each ROP. This means that for recording periods that start for instance 5minutes past the full hour, the first ROP file that is included in the result is theone that is contains data from 15 minutes past to 30 minutes past the full hour.Since it takes some time to setup an WNCS recording, it is recommended thatthe start time of the recording periods is set to a few minutes before the startingtime of the first ROP that you want to include in the result.

Since the usage of different neighbor relations will most likely vary with theweekday and hour, it is recommended to schedule recordings of severalrecording periods during several hours each day for several days in order tosecure reliable data.

The set of cells can include cells belonging to several RNCs. Cells can beselected either directly or saved in cell sets to be reused in other recordings.A recording can even encompass an entire RNC: WNCS would then checkwhich cells belong to the RNC at the start of each recording period, and includethem in the recording. Consequently, new or removed cells in the RNC will beconsidered by an ongoing recording.

In systems with both GSM and WCDMA cells from Ericsson, recordings canbe scheduled for both GSM cells and WCDMA cells from the same window.GSM cells and WCDMA cells can be combined in the same recording if NCS isinstalled.

Any column of the report can be sorted in ascending or descending order.

By default, the part with the defined neighbors, is sorted by ascending numberof reports above the absolute Ec/No threshold, giving the lowest number ofhandover attempts at the top.

The part with undefined neighbors is, by default, sorted by descending numberof reports above the absolute Ec/No threshold, giving the highest number ofreports at the top.

It is possible to change neighboring relations from the Cell Report by usinga Change Order. The Change order contains different parts for adding newneighbor definitions, removing already existing neighbor definitions, andchanging the priorities of already defined neighbors.


The Probable Neighboring Cell Report shows all surrounding WCDMA cellsthat are candidates for neighboring cell, which means that the cell is consideredas probable for handover from the serving cell.

6.4 GEO-W

This chapter describes the GEO-W functions.

6.4.1 Defining new GEO-W recordings

A GEO-W recording is defined from the new recording menu item in the RNOmain window. In the GEO-W New Recording window, the user must supplyall parameters that are needed to start a GEO-W recording. The followingparameters are available when defining a GEO-W recording:

• Recording name. The name of the recording. The result created by thisrecording will have the same base name.

• Recording Time. A GEO-W recording consists of one or more consecutiverecording periods. The time for each recording period can be individuallyset. It is possible to create a recording that is repeated daily or on selecteddays of the week.

• Cell Set (or cells).

• If GEO-W reuses RES measurements scheduled by WMRR recordingsinstead of creating its own. It is important to ensure that WMRR specifiesCPICH / Ec/No or RSCP.

• If the output file includes calculated positions.


• Measurements. UE fraction and capacity that reports periodically.

Capacity limitation significantly depends on the parameters above.


The maximum number of recording periods on selected weekdays is four perday.

Technical Specification

7 Technical Specification

This chapter describes the characteristics and limitations of the RNOapplications.

7.1 Authority Handling

The authority to use different functions in RNO is administered by means ofTSS.

7.2 Capacity and limitations

This chapter describes the RNO capacity and the limitations in OSS, RNC andBSC that have an impact on RNO.

7.2.1 Capacity limits in the BSC

There are three recording functions in the BSC that the RNO applications use,BAR, RIR and MRR. There are also two functional extensions based on BAR,GSM-WCDMA Active BA-list Recording (GW-BAR) and CCR that are usedby the RNO applications. For more information about the capacity limits ofthe recording functions, refer to BSC Functional Specification, Active BA-listRecording, Reference [13], BSC Functional Specification, Radio InterferenceRecording, Reference [14] and BSC Functional Specification, MeasurementResult Recording, Reference [15].

MML commands are sent from a RNO recording to each BSC through the EAMinterface which is a shared resource that is used by other OSS applications.The following table shows the number of MML commands for a typical recordingwith the assumption that all cells in a BSC are included in the recording. Ifall cells are not included, a list with the specific cells must be sent and thenumber of MML commands can increase compare to the figures below. TheStart column in the table shows the number of commands per BSC at start of arecording period. The End column show the number of commands to end it.

131155 34-APR 901 0112 Uen D2 | 2010-05-10


MRR 5 3

NCS 7 3

Other BSC limitations that have an impact on RNO:

• A cell can only be connected to maximum one BAR (includes GW-BAR andCCR) recording, one RIR recording and one MRR recording at any giventime. See Table 3 for recording types used in RNO.

• There can be maximum 10 active BAR (includes GW-BAR and CCR)recordings, 10 RIR recordings and 10 MRR recordings active in a BSC atany given time.

• The BSC supports that all recording functions are active in all cells in aBSC but there is a limit for BAR for the total number of test-frequenciestimes the number of cells that can put a limit to the number of cells therecording can be active in.

• The BSC has a limitation for the total number of frequency/cell combinationsincluded in a recording. The limitation is set by SAE 533 that specifies“NO OF GSM TEST FREQUENCY INDIVIDUALS IN ACTIVE BA-LISTRECORDING”. The number of individuals is determined by all possiblecombinations of test frequencies and active cells connected to the activeBA-list recording. Refer to RNO, Radio Network Optimization, SystemAdministrator Guide Reference [4] for information about changing theSAE 533 value.

7.2.2 Capacity Limits in the RNC and RBS

The RNO applications use the PM functions in the RNC to collect data aboutthe network performance. The PM functions are GPEH and Statistics (STAT).Both RNC and RBS stats are used by RNO. Only one RES measurement can

132 155 34-APR 901 0112 Uen D2 | 2010-05-10


be active in an RNC at any given time. For the current limit on the total numberof counters that can be active in each network element, refer to WCDMA UserDescription, Performance Management in WCDMA, Reference [17].

A WMRR recording activates RNC and RBS counters. Each bin in thehistograms in WMRR is counted as one counter. Each RES histogram contains18 bins and each RBS histogram contains 38 bins. For example, a WMRRrecording with 12 RES histograms (the maximum value) and all 7 spreadingfactors for the RBS measurements included would give a total of 18*12= 216RNC counters per cell and 38*7=266 RBS counters per cell. According tothe UTRAN O&M Traffic Model (refer to UTRAN O&M Traffic Model P7 MD,Reference [18]) there are in average 3.75 cells per RBS and 882 cells perRNC. That would mean that a RES recording with those settings would activate190512 RNC counters per RNC and 984 RBS counters per RBS.

A WNCS recording activates both GPEH events and RNC counters.The GPEH events are INTERNAL_SOHO_DS_MISSING_NEIGHBORand INTERNAL_SOHO_DS_UNMONITORED_NEIGHBOR. The eventsINTERNAL_RECORDING_FAULT and INTERNAL_MP_OVERLOAD are alsoread if they are present in the GPEH file. For more information about GPEH,refer to Performance Recording Characteristics WCDMA RAN, User Description,Reference [16]. The counters are pmRIAddAttemptsBestCellSpeech andpmRIAddSuccessBestCellSpeech. Both counters are activated on cell relationlevel and for each WNCS recording they are always activated for all cells in eachRNC regardless of the number of cells included in the recording. If we assume882 cells per RNC and 20 defined neighbor relations for each cell this wouldmean that a typical WNCS recording will activate 35280 counters per RNC.

7.2.3 Capacity Limits in OSS

When starting a WMRR, WNCS or FFAX-W recording RNO registers a profilein PMS. RNO uses one profile for each type (GPEH, STAT RNC, STAT RBS)for each RNC regardless of the number of recordings. However, when aprofile needs to be updated there will be overlapping profiles for the sametype and RNC for a short time. For more information about PMS, refer toPM, Subscription Profiles and Performance Monitoring, Function Description,Reference [19].

7.2.4 Capacity of the RNO Applications

The capacity described here assumes that no RNO activity other than therecording(s) of the specified type is run at the same time. If the combinations ofdifferent recording types are run in parallel, then the supported capacity can becalculated as a weighted average based on the limits in Table 4.

For example, in case of the combination of WNCS and WMRR with only RNCmeasurements, the ratio between WNCS and WMRR cell weight is 2 to 15,thus 1 WNCS cell capacity weighs 7.5 WMRR cell capacity. The supportedcapacity is still 15000 WMRR cells, which is 7.5 times the number of cells used

133155 34-APR 901 0112 Uen D2 | 2010-05-10


in WNCS recording(s) plus the number of cells used in the WMRR recordings.That is, 1000 WNCS cells plus 7500 WMRR cells.

Unless stated otherwise for a certain application, there is no hard limit onthe number of cells that can be added to a recording, or on the number ofsimultaneous recordings that can be run, but the supported capacity is asdescribed here.

Application Maximum supported capacity

CCE CCE recording(s) with a maximum of 5000 cellsin total.

FAS FAS recording(s) with a maximum of 5000 cellsin total.

134 155 34-APR 901 0112 Uen D2 | 2010-05-10


Application Maximum supported capacity

WMRR WMRR recording(s) with a maximum of 15000cells in total, when only RNC measurements areselected.

WMRR recording(s) with a maximum of5000 cells in total, when both RNC and RBSmeasurements are selected.

WNCS WNCS recording(s) with a maximum of 2000cells in total.

The RNO load on the system is highest during the start and stop of recordingperiods for the GSM applications. To avoid possible performance problems thenumber of recordings with recording periods that start and stop at the sametime must be kept to a minimum. The WCDMA applications (FFAX-W, WMRRand WNCS) parse data from the recordings continuously (after every ROP) andtherefore maintain a load on the system during the whole recordings.

7.2.5 RNO limitations

• To run BAR or RIR-recordings manually and use RNO from the same OSSat the same time is not recommended since this can cause inconsistencies.For information on how to avoid problems, refer to RNO, Radio NetworkOptimization, System Administrator GuideReference [4] .

• There can be maximum 4 recording periods in a recording definition wherethe combined length of the recording periods, including the time betweenperiods, cannot exceed 24 hours. These recording periods can be repeatedfor multiple days in the recording.

• By default, the minimum time between two recording periods is 15 minutes.This configuration parameter is set and can be changed in the PDB(parameter database). It is not possible to specify a shorter time betweentwo recording periods than what is stated in the PDB.

CCE

• A CCE recording can record up to 10 competitors

• The maximum number of cell sets for a CCE recording is 25

• In a CCE recording, a frequency/NCC combination must be unique toone competitor

FAS

• It is possible to specify up to but not more than 150 frequency numbers ina FAS frequency set

• A FAS recording is able to record on up to but not more than 150frequencies

135155 34-APR 901 0112 Uen D2 | 2010-05-10


• The maximum number of rows of an ICDM is the same as the maximumnumber of cells that can be included in one OSS

• The maximum number of elements in a given row of an ICDM is the sameas the maximum number of cells that can be included in one OSS

FFAX-W

• There can be maximum 5 FFAX-W recordings in an RNC at the same time.

FOX

• An evaluation period of a FOX recording is able to continue for at most31 days

GEO-W

• There can be only one GEO-W recording in an RNC at the same time.

• The feature can be active for up to 5000 cells at the same time, whenpost-processing is selected, however, for scenarios with a very highreporting frequency (every 2 seconds) and high UE Fraction (100%), thelimit is 1000 cells at the same time. This is a hard limit in GEOW. Thelimit is ramped up to 5000 proportionally with UE fraction and reportingfrequency according to the following formula:

Capacity = 500 * UeFr * Freq

where

Capacity is the maximum number of cells, capped at 5000.

UeFr is the UE fraction expressed as "one in every n user"; it can be 1, 2,3, 4, 5.

Freq is the reporting frequency (periodicity) in each UE, expressed as"one in every n second"; it can be 2, 3, 4, 6, 8, 12, 16, 20, 24, 28, 32, 64.E.g., a 50% UE fraction (thus every 2nd user equipment) with a reportingfrequency of one report in every 4 seconds per user equipment, gives acapacity of 4000 cells.

• When post-processing is selected, GEO-W can process 3000000positioning events per a 15-minutes ROP as a maximum if no eventsof other type are present in the GPEH file(s). This translates into amaximum of 6.7 active CELL_DCH users per cell in average at a maximumUE fraction (100%) and shortest sampling period (2 s). If other type ofevents are also present in the GPEH files, then the capacity of GEO-W isdecreased depending on the number of other events. In average, GEO-Wcan process (skip when parsing) events of other type about 4 times fasterthan positioning events.

NOX

136 155 34-APR 901 0112 Uen D2 | 2010-05-10


• An evaluation period of a NOX recording is able to continue for at most31 days

TET

• It is possible to run a TET-recording with up to 16 test frequencies/BSICcombinations (test transmitters). This means that it is possible to run arecording with at least four test frequencies and, for each frequency, todefine four BSICs.

WMRR

• WMRR can handle at least 10 active WMRR recordings at the same time.

• There can be only one WMRR recording in an RNC at the same time.

WNCS

• There can be maximum 5 WNCS recordings in an RNC at the same time.

7.3 Database requirements
