Channel Administration


03813-LZU 108 3704 Uae Rev F 2

The capability of the feature Channel Administration is to select and allocate one or more suitable channels in each traffic situation that requires a set of channels. If several types of channels are possible to allocate in a specific traffic situation, the order in which the different types are preferred is defined.The operator can choose among eleven pre-defined Channel Allocation Profiles (CHAPs).

Provides the possibility to choose between eleven pre-defined channel allocation strategies (CHAPs)


03813-LZU 108 3704 Uae Rev F 3

Before the selection and allocation of a set of channels, a cell has been selected by the locating algorithm or by the idle mode cell selection mechanism. There are three main situations in which a set of channels is allocated: Immediate assignment - when a connection is to be established, a channel forsignalling has to be allocated. Depending on the traffic situation and the chosen CHAP, the channel could be either a Stand alone Dedicated Control Channel (SDCCH) or a Traffic Channel (TCH). Assignment - after an Immediate assignment on SDCCH, when a channel for speech/data is needed, a TCH has to be allocated. Handover - when a connection in use is to be changed, a new channel has to be allocated.



3 main situations when a channel is allocated Immediate assignment Assignment Handover


03813-LZU 108 3704 Uae Rev F 4

In order to select a suitable type of channel, the following data is needed: Traffic case the traffic case in which a set of channels needed. This can for example be Immediate Assignment. Preferred subcell the preferred subcell, Overlaid (OL) or Underlaid (UL), according to the OL/UL evaluations in Locating. Channel mode the channel mode, speech/data or signalling, for which the channel will be used. Channel service the channel service, a list of channel types and Speech Versions (SVs)/data rates in order of preference. Multislot data the multislot data, number of channels requested, fixed or flexible number of channels and the Channel Set Indicator (CSI), to be used for the multislotconnection.There are 6 different RT:sRT1.1 OL/TCH/FRRT1.2 OL/TCH/HRRT2.1 UL/TCH/FRRT2.2 UL/TCH/HRRT3 OL/SDCCHRT4 UL/SDCCH

The speech version decides which speech coding to use for the channel type. Up to three versions may be used for TCH/FR and TCH/HR respectively. The speech coding is performed in the mobile station (MS) and in the transcoders.


Speech Versions

In Ericssons GSM System R10 the following speech versions are available: TCH/FR/SV1 (full rate) TCH/FR/SV2 (enhanced full rate) TCH/FR/SV3 (AMR full rate) TCH/HR/SV1 (half rate) TCH/HR/SV3 (AMR half rate)


03813-LZU 108 3704 Uae Rev F 7

An RT is an unique type of channel. It is a combination of subcell, channeltype and rate.Enhanced full rate is administered in the same way as FRIt is determined by the MS and BTS capabilities


Resource Type (RT)

An MS can be assigned 6 different Resource Types (RTs)

RT1.1: full rate TCH in the overlaid subcell (OL/TCH/FR)RT1.2: half rate TCH in the overlaid subcell (OL/TCH/HR)RT2.1: full rate TCH in the underlaid subcell (UL/TCH/FR)RT2.2: half rate TCH in the underlaid subcell (UL/TCH/HR)RT3: SDCCH in the overlaid subcell (OL/SDCCH)RT4: SDCCH in the underlaid subcell (UL/SDCCH)

A CHAP is a list of all possible Selection Type (STs). Each ST is assigned one Resource Type Priority List (RTPL). There are eleven profiles to choose among by the parameter CHAP. Each profile represents a specific channel allocation strategy.


Channel Allocation Strategies / Profiles

There are eleven pre-defined CHAPs

Different Strategies differ with respect to Immediate assignment on TCH overlaid subcell as last resort or not at all pre-dominantly ph 1 or ph 2 MSs Channel needed provided by the MSC in the paging message or not

Ph1 or Ph2: The possibility to differentiate between call setup and SMS at Immediate assignmentCHAP 3 might be good if heavy load (SMS) on the SDCCH(channel needed is an info element in the paging message, not supported by our MSC in R8.)CHAP 7 can be used for an operator defined strategyNote that for CHAPs 1-2 Im.ass. on TCH is not allowed for STs that are used for location updating or GSM phase 2 MSs sending or receiving SMS.CHAPs 2-3 differ in that, in the second case (CHAP 3) MS terminated calls is allocated a TCH as last choice since it cannot be distinguished from MS terminated SMS.The difference between CHAP 4 and CHAP 1 is probably emergency calls and call re-establishments which here is directed to TCH first. (Both MT or MO must first go to SDCCH since it can be an SMS)

However, at Immediate Assignment, overlaid subcell will be prioritized beforeunderlaid subcell, and at Intra Cell handover due to HR Packing, where UL is the preferred subcell, OL subcell is available as a second option. For more information about BCCH in OLCHAP 9: This profile provides a channel allocation strategy similar to the default profile. However, at Inter cell handover and Assignment to other cell the channel allocation is restricted to UL subcell even if the preferred subcell is the OL.CHAP 10: This profile provides a channel allocation strategy similar to profile 5. However, at Inter cell handover and Assignment to other cell, UL subcell will be prioritized before OL subcell even if the preferred subcell is the OL.


03813-LZU 108 3704 Uae Rev F 12

This profile provides a channel allocation strategy similar to the default profile. However, if an UL subcell is preferred, and there is no available idle channel in the UL subcell, an attempt is made to allocate a channel from the OL subcell as a last resort. The purpose of this strategy is to avoid unsuccessful handovers or blocked calls when the UL subcell is congested, but there are available idle channels in the OLsubcell. The drawback is that the OL subcell may serve MSs outside its defined serving area, which might lead to excessive interference.

Differential Channel Allocation:The operator can assign a Channel Allocation Priority Level (CAPL) to a specific mobile subscriber in the subscription data in the HLR. The HLR includes the CAPL in the subscriber data that is transferred to the MSC/VLR. The MSC/VLR sends the CAPL in the Assignment Request message to the BSC. The MSC/VLR also sends the CAPL in the Handover Request message at inter-BSC handover during the assignment procedure

03813-LZU 108 3704 Uae Rev F 14

Before the ST is determined, three checks are made:If the traffic case is "Inter-cell handover due to cell load sharing", the cell load sharing conditions are checked and might result in an allocation failure. For a GSM 900 mobile, the number of idle full rate channels is determined according to the status of the parameter EBANDINCLUDED for all available GSM 900 bands. If the status of this parameter is OFF then only idle full rate P-channels are considered. If the status of this parameter is ON then all idle full rate channels in all available GSM 900 bands are considered. If the status of the parameter EBANDINCLUDEDfor all available GSM 900 bands is OFF and the MS is using an E-channel, the allocation fails. Cell Load Sharing is only applicable for singleslot connections. For a GSM 900 mobile, if channel allocation is requested for subcell change due to Subcell Load Distribution, the status of the parameter EBANDINCLUDED for all available GSM 900 bands is OFF and the MS is using a channel that is not in the P-GSM 900 band, the allocation fails. If multislot connections are not allowed in either the BSC or in the cell and a flexible number of channels are requested, the number of requested channels is set to one. The channel allocation will then proceed as if it was a singleslot connection. If a fixed number of channels are requested when multislot connections are not allowed, the allocation attempt fails.


Resource type selection (I)

Before the ST is determined, three checks are made: In case of an inter cell handover due to CLS, the CLS

conditions, by means of number of idle full rate channels, are checked. The parameter EBANDINCLUDED determine if idle FR E-channels are considered or not.

If a subcell change due to SCLD for a GSM 900 MS is requested and EBANDINCLUDED=OFF and the MS is using non P-GSM 900 channel, the allocation fails.

If a flexible number of channels of a multislot connection are requested and the BSC (and cell) doesnt support multislot connections, the request is set to one channel.


03813-LZU 108 3704 Uae Rev F 15


Resource type selection (II)

After the selection of an ST, an RTPL according to CHAPis chosen

A search for idle channels of the RTs specified in the RTPL is done

When idle channels are found, part 2 of the Channel allocation algorithm is used

If all RTs are searched and no idle channels are found, a search for other channels is started: Look for GPRS/EGPRS PDCHs for pre-emption If HSCSD is used, request a downgrade of a HSCSD connection If eMLPP is active, a search for a suitable channel is done

accordingly


03813-LZU 108 3704 Uae Rev F 16

It is possible to use the feature for statistics only or for statistics and Channel Administration


Idle Channel Measurement (I)

Idle Channel Measurement is a feature that provides measurements of Uplink interference on idle channels (both SDCCHs and TCHs)

It provides Channel Administration with information about the most suitable idle channel for a connection


03813-LZU 108 3704 Uae Rev F 17

A slight displacement of the statistics of interference levels of the idle channels in a cell occurs when switching this feature on for channel allocation (compared with just using the feature for measurements). The reason is that highly interfered channels are not used as much with Idle Channel Measurements as without.Therefore there will be a larger amount of idle channels in higher interference bands (2 to 5).. Also if dynamic MS control is switched on a decrease is expected.

TCH Channel Selection (part 2)

In the channel selection case, in all traffic cases except intra-cell handover and HR packing, the following process is applied:

1. If HR is requested, select the group of idle channels that have been partly allocated for HR (in order to save the completely idle TCHs for FR). Otherwise select the group of idle FR channels.

2. For an MS that is capable of handling several GSM channel bands: select the group of channels according to the parameter FBCHALLOC. The value of this parameter is used to determine if an idle TCH on the BCCH frequency band or subband should be allocated first, last or if there is no preference.

3. Among these channels, the group of channels that doesn't have 64 kbps Abiscapability are preferably selected.

4. Among these channels, the group of channels that has the least number of E-TCHsare preferably selected.

5. Among these channels, the group of channels that has the least number of G-TCHsare preferably selected.

6. Among these channels, the group of channels that are not capable of receiving Extended Packet Channel Request messages are preferably selected.

7. Among these channels, the group of channels that is not marked having lower priority for CS due to PS (These can be used to expand a PSET) are preferably selected.

8. Among these channels, select the group of channels according to the parameter CHALLOC. The value of this parameter is used to determine if an idle non-hopping TCH on the BCCH frequency should be allocated first, last or if there is no preference.

9. Among these channels, select the group of channels that belong to a CHGR with SAS: Quality Consideration (first choice)MAIO Consideration (second choice)Multislot Consideration (last choice)

Intra-Cell HandoverIn the traffic case intra-cell handover, it is important to find channels with characteristics that differ compared to the characteristics of the originating channel.

1. The group of idle channels according to the following intra-cell handover strategy is selected. Note that it is possible to go from non-hopping channels to hopping channels, and vice versa.

Without frequency hopping:2.1 Among the idle channels, select the ones

that are on a different frequency than the

current channel.

2.2 If no idle channels have been found with

the criterion above, select the idle timeslots

that are on the same frequency as the

current channel, but with different timeslot

numbers than the current channel.

3. Continue the selection at step 1 in the TCH Channel selection for singleslot connection.

With frequency hopping: 2.1 Among the groups of idle channels, select the ones

that belong to another channel group than the current channel.

2.2 If no idle channels have been found with the criterion above, (e.g. there are only one channel group defined in the cell), select the idle channels in that channel group, but with different timeslot numbers than the current channel.

2.3 If no idle channel has been found with the criteria above, select the idle channels on the same channel group and timeslot as the current channel.

SDCCH Channel SelectionThe following process is applied for SDCCH Channel selection.

1. For an MS that is capable of handling several GSM channel bands: select the group of channels according to the parameter FBCHALLOC. The value of this parameter is used to determine if an idle SDCCH on the BCCH frequency band or subband should be allocated first, last or if there is no preference.

2. If the Idle Channel Measurement feature is active, the group ofSDCCHs with the lowest interference band is selected among these channels.

3. Among these channels, the group of SDCCHs hopping over as many frequencies as possible is selected.

Halfrate

Halfrate TCH Packing: After a successful completion of a channel allocation attempt, a check is made to see if the feature Half Rate TCH packing shall be initiated

Dynamic Halfrate Allocation: This feature optimizes the usage of capacity when the traffic load is high, whilst it offers the best possible speech quality when the traffic load is low. This is achieved byallocating FR or HR TCHs for new connections in accordance with the traffic load in the cell. At high traffic load TCH/HR is allocated and at low traffic load TCH/FR is allocated

Dynamic FR/HR Mode Adaptation: If there are less available TCHsthan a selectable threshold and if packing of HR channels can not be done the next step is to change the mode of DR capable MSsallocated on FR TCHs to HR for DR capable mobiles for an ongoing call

In dual transfer mode, the mobile station has a CS connection to the network (used for transfer of speech) and has simultaneously allocated radio resources on one or more PDCHs. The mode is always entered from dedicated mode, that is a CS connection is established first (by using the channel allocation algorithm in this document) and then PS resources are added. The CS connection and the allocation of radio resources on PDCHs are coordinated by the network, such as to comply with the DTM multislot class defined for the mobile station. Up to three adjacent timeslots can be allocated for DTM to be used for CS and PS connection. The timeslots allocated in each direction are contiguous in order to allow for ordinary Type 1 MS operation (the MS is not required to transmit and receive at the same time).

Parameters

CHAP is used for selecting the Channel Allocation Profile. The parameter is set per cell.

CHALLOC is used to determine whether a non-hopping TCH on the BCCH frequency should be allocated first (=1), last (=2) or with no preference (=0) for CS. The parameter is a BSC exchange property, and is set per BSC.

FBCHALLOC is used to determine whether a channel in the BCCH frequency band or subband should be allocated first (=1), last (=2) or with no preference(=0) for CS TCH and SDCCH allocation. The parameter is set per BSC.

SAS is used specify the Singelsot Allocation Strategy for a CHGR. The three options are: QUALITY, suitable for CHGRs planned for mainly speech. MAIO, suitable for CHGRs planned for tight frequency reuse networks,

e.g. 1/1 or 1/3. MULTI, suitable for CHGRs planned for mainly multislot data.
