Three Ways To Configure The RNC1. MML (Man Machine Language) commands:

– These are 4-letter-commands, starting with Z, e. g. ZABC.– Nearly every transmission related setting is configurable via MML command.– May be automated by batch-files.– CoCo objects cannot be created with MML commands

2. RNW (Radio NetWork) Object Browser GUI (Graphical User Interface):– Graphical software application stored in the NEMU of the RNC, downloaded

and started via Application Launcher.– Used to create all radio configuration related parameters (no in this session)– Also used to create CoCo related parameters for Iub (shown later).– Automatically configures a lot of parameters by using templates and rules.

3. RAML1.0 XML files:– Coming from NetAct Plan Editor, downloaded to NetAct Radio Access

Configurator in OSS, from there downloaded to RNC.– Contains mainly radio configuration related parameters for each NodeB.– CoCo creation via RAML1.0 XML files.

Brief introduction to MML-commands• The first time in touch with MML-Syntax might cause some confusion.

– The first letter is always a „Z“, this is needed for the system to start from the top of the command hierarchy.

– The next two letters determine the command family– The last letter is the command itself. Not always but often this letter shows what

command is behind, e.g. „C“ for Create, „M“ for Modify, „I“ for Interrogate, „D“ for Delete.• Considering e.g. TRS issues, the planner fills the RNC data built with all relevant

input. There are mandatory and optional tables, depending on needed technologies and features.

• As this data built contains also a lot of SS7, ATM-routing & IP topics, often other planners of different fields must get involved

• When data built is complete the integration engineer receives the tables and creates command strings

• Usually small changes or some parameter adaptations in the RNC configuration are directly entered in the system via MML-commands.

• In case of major changes or a complete new configuration respectively set up of an RNC it works different

• Integration / Commissioning engineers produce all command strings and import them e.g. with the HIT-macro.


MML-Commands and their structure

• An MML command can contain just one item (e.g. interrogate), but it possibly consist of 25-30 parameter settings.

• Each parameter is separated by a comma “ , “ from the next one• These parameters are then combined into groups, separated by a colon “ : “ from

each other. E.g: ZLAC:A,B,C,D:• There might be groups were many parameters are given, but only one/some input

is required or the provided default is suitable. In this case the input is skipped with the comma. Even a whole command group could remain empty and is just terminated with a colon. Here are some examples based on ZLAC:A,B,C,D:

• A=1, B=2, C=N/A, D=YES =>ZLAC:1,2,,YES;• A=1, B=N/A, C&D=Default =>ZLAC:1;• A&B&C=Default, D=YES =>ZLAC:,,,YES:;• All values Default or N/A =>ZLAC:;

• Each command starts with a „Z“ and ends with a semicolon “ ; “• Example: ZOBC:A,B,C,D:F,G:J;

• On the next slide there‘s an example how to create a MML-command string with given input, based on the command syntax.


Example: Creating & Activating 2 SDH InterfacesSyntax:YAN: <SDH exchange terminal index>..., [<higher order path number> | <higher order path number>, <lower order path number>]: [<SES BIP threshold>]: [<SD BER threshold>]: [<SF BER threshold>]: [DIA = (ON | OFF) | LINE = (ON | OFF) | LASER = (ON | OFF)]...: [VC3 | VC4 | VC3VC11 | VC3VC12 | VC4VC11 | VC4VC12]: [SDH | ATMML | SONET]: [ASYNCH | BITSYNCH | BYTESYNCH];

Parameter Input:SDH exchange terminal index: 0 and 4 => 0&4higher order path number: N/A for VC4 => lower order path number: N/A for VC4 => :SES BIP threshold: 2400 (Default set by system) => :SD BER threshold: 5 (Default set by system) => :SF BER threshold: 5 (Default set by system) => :diagnostic loopback status: N/A for tests only =>line loopback status: N/A for tests only => :laser status: ON => LASER=ON:VC mapping: VC4 => VC4:SDH protocol: SDH => SDH:lower order path mapping mode: N/A for VC4 =>

=> ; to execute command

Final MML command: ZYAN:0&4::::LASER=ON:VC4:SDH;

The RNC Data built• Data built is used when new RNC is planned• Data built is used to carry out major changes in an existing RNC• Data built consist of an Excel-file with 50 sheets (tables) for

– PDH Physical Layer Parameters– SDH Physical Layer Parameters– ATM Parameters– SS7 Parameter– Digit Analysis Parameters– IP Parameters– Synchronization Parameter– Other Parameters

• Planning engineers are filling tables with all needed input• Integration engineers use these tables to enter commands into RNC• Each sheet is in the order as integration commands are executed• Each table is built up in the order of parameters for MML command• Accordant MML-command(s) are always within table• Often databuilt is used to display CoCo objects, even though they‘re not

entered with MML commands

• The Physical layer Trail Termination Point (PhyTTP) is used to hide the properties of the physical resources from the upper protocol layers.

• It is configured between the physical layer and the ATM layer. • To detect failures in the ATM transmission, the physical layer supervises

the PhyTTP.


Required planning parameters for PhyTTP

(1) Defined in previous slides(2) This parameter identifies the type of the

payload in the data transfer. Possible values for SET and SDH protection group are ATM and PPP. The default is ATM. For PET and IMA group the only possible value is ATM.

• To create the ATM resources on the Iub, we should use the RNC RNW Object browser. For other interfaces we use MML.

• Nevertheless, the same parameters for ATM resources are used for the all RNC interfaces:– Iub– Iu-CS– Iu-PS– Iur– Iu-BC– All related SS7 signaling channels– O&M

• Iub VP/VC to created with CoCo objects• The needed resources are

– ATM interface– Access profile– VPLtp for CBR traffic– VPLtp for UBR traffic– VCLtp for CBR traffic– VCLtp for UBR traffic– VCLtp for UBR+ traffic (RAS06!)


Required planning parameters for ATM interface in the RNC

(1) Defined on previous slides(2) UNI = User-Network-Interface and NNI = Network-Network-Interface(4) Max VPI bits value is 8 for a UNI interface and 12 for a NNI. Consider limitations: Total

VPI/VCI bits for RNC is 14, for the AXC it’s 13(5) A PDH interface can support up to 7 VCI bits, while an SDH one supports up to 14 bits(6) UPC (Usage Parameter Control) and NPC (Network Parameter Control) stands for Policing

functionality. The default value is E (enabled). This means it is enables for CBR traffic. Note: Before RAS5.1 the bandwidth was also a parameter of the Access Profile. It was cancelled

the capacity is now directly derived from the PhyTTP.

What is Signalling ?

• Definition: any transfer of data that enables speech and data connections between users

• In PSTN signalling is needed only for:– call establishing– call release – call maintaining

• In GSM/WCDMA signalling is needed for:– handle speech and data connection (set up, supervise and release a call)– handle mobility management (location update, handover)– handle subscriber administration (including all basic and supplementary GSM services)

• In GSM/WCDMA: signalling is any transfer of data that enables speech and data connection between users and supports mobility management and GSM services handling

SS7 Network Structure (1)Signalling Points: Nodes in an SS7 network are called signalling points (SP’s):Types of signalling points: • SPC: Signalling Point Code is a binary code uniquely identifying a signalling point in a signalling network• SEP: Signalling End Point is a network node that originates and/or terminates signalling messages• STP: Signalling Transfer Point is a signalling point that transfers messages towards a destination point• The Signalling Point is usually in the RNC a SEP and in the MGW a SEP

In SS7 there are 4 Signalling Networks:• NA0 – National zero, usually used in PSTN and inter-operator connections • NA1 – National one, used by GSM and other operators• IN0 – International zero, used for connections to international gateway • IN1 – international one (usually spare)• A SP can operate in a maximum of 4 signalling networks (e.g. MSC)• In 3G RAN we always use NA0 or NA1


SS7 Network Structure (2)• Signalling Link - a signalling link connects two signalling points. In RAN, one signalling

link is associated to one signalling VCC. All SS7 signalling links in 3G RAN (both ED2 and RAN04), are based on ATM transport and AAL5 adaptation layer.

• Signalling Link Set - a set of signalling links directly connecting two signalling pointsTraffic between SP’s is generally load-shared between all links in a linkset

• Signalling Route - a predetermined path described by a succession of signalling points that may be traversed by signalling messages directed by a signalling point towards a specific destination point

• Signalling Route Set - combination of all permitted signalling routes that may be used to pass signalling messages from a signalling point to a specific destination

Each Signaling Link within a Network Element has a Signaling Link Number. It is unique within one NE and the corresponding link number at the remote NE is independent from it.

Each Signaling Link within a Signaling Link Set has a Signaling Link Code. It is unique within the Link Set and is independent from the Signaling Link Number

In the current network releases there are no different routes for signaling links. Hence there‘s always one route from source to destination. That is why we directly create the route set as it contains the one and only route. In the future when networks become more and more meshed there will be different routes for higher resilience in signaling message transport

What is needed before setting SS7 in 3G RAN• Get the signalling point code allocation scheme from telecommunications administration. The

allocation scheme contains the signalling point codes to be used in the own signalling network.

• Define the format of the SPC: length 14, 16 or 24 bits, Also define if the signalling point code should be allocated into sub-fields e.g. 3-8-3 bits or 8-8-8 bits format

• Define the signalling network allocation: Find out if, for example, RNCs are configured to NA1 signalling network and MGW to NA0 signalling network.

• Define the network structure concerning SEPs and STPs

• Define the physical transmission paths and the VPI/VCI numbering plan.

• In case of IP transmission, define source and destination IP addresses.

• Determine signalling traffic between two NEs in order to define the link size and capacity

• Identify the signalling links within a link set by defining signalling link code (SLC).

• MVI: Find out if there are any restrictions concerning the other vendors' interconnecting network elements concerning timer values, address field of messages or managementprocedures. Note: This mainly concerns the signalling link set parameter set!

• Find out what network elements are included in the signalling network where the SCCP (e.g. RANAP, RNSAP) exists and define the applications that exist in different network elements and the type of addressing (GT or SPC and SSN) used to send messages to them

• Find out what kind of global titles are used (for example, if roaming agreements and used IN services affect the global titles)

When R99 CS-Core network will be upgraded to R4, major HW changes must be carried out. The MSC will be replaced by an MSS (MSC-Server). The MSS controls the interconnected MGWs and only signaling traffic is transmitted and the user plane traffic is transported between MGWs. The signaling point of the MGW is then a STP, RANAP messages are forwarded to MSS, ALCAP(AAL2sig) messages are processed

STP for RANAP messagesSEP for ALCAP

• Since Rel4 was introduced all new Core networks are based on this release• Existing Core networks did or will migrate sooner or later• With Rel4 the MSC becomes superfluous, the switching will be done by the

MGW but controlled by the MSS (MSC Server). This is called Softswitch!• Therefore the ALCAP (AAL2sig + MTP3) will be terminated in the MGW but

the RANAP will be terminated in the MSS• Both protocols can use the same signalling link or can be in two different

links. – In case of 2 VCC the traffic passes the MGW transparently– In case of 1 VCC the MGW acts as a STP (Signalling Transfer Point) for RANAP

messages• The IP connection from the MSS to the MGW is called MEGACO (Media

Gateway Control Protocol ) or H248 and is controlling the MGW• Several MGW could be connected to 1 MSS via the SIGTRAN links• The connection between MGWs is the Nb-interface

SS7 definition in the RNC

• The following steps are needed in order to activate the SS7 signalling in the RNC, and inter connect it to the rest of the SS7 network:1. Define the RNC’s own MTP parameters and needed services (defined once during RNC

Setup)2. Define the RNC’s own SCCP signalling point and subsystems (defined once during RNC

Setup)3. Create the SS7 signalling links4. Create the SS7 signalling link set5. Create the needed route set

Signalling over IP between RNC and MGW is a new feature. This is not directly related to R4.

Due to IP settings Signallingover IP is handled later in the session after Iu-PS interface.

In addition to the RNC own SPC, the destination network element signalling point code (DPC) and the signalling network previously defined, the following parameters should be planned in order to define the SCCP subsystems


Signaling Point and Subsystem Parameter Set NumberIn the RNC we have extra parameter sets which do not appear in the data built. This applies for the Signaling Point, the Subset and for the Signal link Links and Routes as well. These sets usually exist already in the RNC in different editions (set0, set1 etc.) and contains quite some parameters. In other words depending on the connected signaling point (equipments SS7 attributes)a specific set is chosen. Even then it is possible that some parameters have to be modified. This is usually done by SS7 planners familiar with the details, decisions might be based on IOTs.

SCCP Subsystem Parameter SetSCCP Subsystem Parameter SetThis set contains 14 parameters which are usually not modified. The Set0 is normally used. Set name is „General“Each set contains the following parameters:

•Q714_T_COORD_CHG•Q714_T_IGN_SST•A_INTERF_APPLIC•A_INTERF_ERR_IGNORED•TRANSLATION_SELECT•CALLING_ADDR_MODIFICATION•CSCC_ALLOWED_OUT•CSCC_ALLOWED_IN•TRANSLATE_AT_DPC_IF_DPC_SSN_GT•TC_TRANSACTION_IDS_THRESHOLD•SEND_CALLING_SSN_IF_RI_SSN•SEND_CALLING_SPC_SSN_IF_RI_GT•KEEP_CLD_GT_IF_RI_SSN•IMMEDIATE_STATE_INFO

Signaling Link Parameter Set Parameter


From CS Core Rel4 onwards, the RNC should have 2 routes towards the CS core:

-One direct route to the MGW handling the AAL2SIG (ALCAP) over MTP for Iu-CS traffic

=> ALCAP terminated in the MGW

-One indirect one towards the MSS using the MGW as an STP for the RANAP traffic

=> RANAP forwarded in the MGW. terminated in the MSS

Route Set Parameter Overview & Conclusions

Conclusions: • The 4 Parameter Sets (SCCP/Subsystem/Link/Routeset) usually remain unmodified.• The planner has only to decide for each of the entities on which Set should be accessed.• Especially for the subsystem and the signalling link it is possible that different sets are used within the

same RNC (databuilt) depending on the interconnected equipment• For special equipment constellation such as MVI certainly technical support from e.g. Interoperability

Testings (IOTs) is required. • For further details of parameter sets check NED• Note: SCCP & Subsystem and each Signalling Link & Route has to be activated with MML commands

after implementation!– SCCP parameter set: Change state to active: ZNGC– SCCP Subsystem: Change state to active: ZNHC– Signalling links: Allow Activation:ZNLA Change state to active: ZNLC– Signalling routes: Allow Activation:ZNVA Change state to active: ZNVC

SCCP Local Broadcast Parameters

The local broadcast status of SCCP subsystems is used to inform the subsystems of the local signalling point about state changes in the SCCP subsystems of the remote signalling points.When you set local broadcasts, remember that the remote network elements have to be configured as well so that they send the status data to your network element (OBM-command).It is not absolute needed to apply the OBM (Remote Broadcast) for own NE, because the response method is always active and all necessary status data will be delivered to the network, it just takes a little longer

SS7 Signaling Transport over IP for RNCIn General:• SS7 signaling transport over IP contains several user adaptation layers. In the RNC only

M3UA is used. • M3UA is a protocol for supporting the transport of any SS7 MTP3-User signaling (e.g. SCCP

messages) over IP using the services of the Stream Control Transmission Protocol (SCTP). • Also, provision is made for protocol elements that enable a seamless operation of the MTP3-

User peers in the SS7 and IP domains. • In RNC, this protocol would be used between a Signaling Gateway (SG) which supports

IPoA (IP over ATM) based SS7 stack. It is assumed that the SG receives SS7 signaling over a standard SS7 interface using the SS7 Message Transfer Part (MTP) to provide transport.

Basic structures of SS7 signaling over IP network:

When IP transport is used in the signaling network, the SEP network element is usually in the IP network. The SEP network element can be Combi-SGSN (serving GPRS support node), but also any other network element, where signaling is transported via the IP network. In the example figure below, there are two Signaling Gateways. If one of them is unavailable, the other one can be used as a backup.

SG=Signalling Gateway


Configuring IP-based signaling ChannelsPurpose:

As SCCP/M3UA/SCTP/IP/AAL5/ATM are implemented to RNC, IP-based Iu-PS, Iu-CS and Iur SS7 signaling stack can be used. SS7 over IP signaling link set is configured in the RNC using IPoA (IP over ATM).

Steps:1. Configure IP over ATM interfaces to the signaling unit (QMF) 2. Assign IP addresses to ATM interfaces of signaling unit (QRN)3. Create static routes if needed (QKC)4. Create association set (Role Client) (OYC) 5. Add SCTP association to the association set (OYA) 6. Add source IP addresses to signaling unit (OYN) 7. Create signaling link set for M3UA (NSP)8. Create signaling route set (NRC)9. Activate route set and signaling link set (NVA/NVC/NLA/NLC)

5 new sheets are added to data fill for M3UA:• Association Set (OYC)• SCTP Association to the Association Set (OYA)• Source IP addresses to Signaling Unit (OYN)• Signaling Link Set for M3UA (NSP)• Association Set Level Parameters (OYM)

Note: Association set is related to Nokia distributed architecture, and it is a Nokia-specific concept!

After configuring the physical and logical connections and the accordant signaling channels the system still doesn‘t know how and where to route the AAL2 traffic. For this we need AAL2 end addresses (A2EA) and a some sets of parameters. The algorithm used for finding the destination and allocating free resources is called Digit Analysis Tree (DA Tree)


Routing objects and digit analysis (1)

The primary purpose of routing is to locate free resources in an ATM network to direct user plane traffic, voice or data, to the desired destination.The digit analysis must be created at the RNC and routing objects must be created at both ends of the Iu-CS and the Iur interface before any user plane connections can be built in theinterface. Digit analysis and routing depend on AAL type 2 signalling. Routing is also dependent on ATM resource handling.The associated signalling is broadband MTP3.The digits to be analysed are the A2EA of the different AAL2 destination

– A2EA of the WAM for Iub– A2EA of the neighbouring RNC for Iur– A2EA of the MGW for Iu-CS

Digit analysis is used in the RNC for finding a route to the respective destinationAn analysis tree (routing tree) is a chain of records in an analysis file, used for analysing the dialled digits, beginning from the first digit in the digit sequence.Each unique set of digits is associated with a destination. Ending up at a destination means that the called party is found.Digit analysis and routing is needed in the connection establishment phase to route the connection to the destination and to reserve required resources for the call.


Routing objects and digit analysis (2)

• Digit analysis gets the address of the other network element and finds the route for the destination by analysing the address.

• Routing also takes care of selecting the resources for the connections to offer desired properties for the connection, for example, by using Quality of Service (QoS).

• With these functions the traffic of connections can be divided between the different routes so that the resources in the network are used efficiently and blocking can be avoided.

• Digit analysis is available in the RNC, where AAL2 level is used for ATM routing. – A suitable Virtual Channel Connection (VCC) candidate under a given AAL type 2 route having free

resources and providing desired properties for the connection needs to be found for routing. – An AAL type 2 connection can be established under this selected VCC.

• Digit analysis determines the destination of a call and selects an AAL type 2 route to the destination. It analyses the digit sequences that it receives. Typically the received sequence is the address of the receiving end (E.164 number, AESA address), but digit analysis may be used to analyse any number sequence that can be analysed hierarchically digit by digit. Digit analysis is capable of analysing addresses up to 40 digits long. In ATM network, digit analysis is used in the Iub, Iur and Iu interfaces.

• Digit analysis and routing are closely connected to each other. Their relationship and objects used in routing and analysis in the RNC are illustrated in the following figure. The figure also shows the order and flow of the routing and analysis functions in call set-up phase.


AAL2 Address Format

• Nokia RNC supports the utilisation of the Local format as RNC own A2EA address.In some multi-vendor network, RNC own A2EA address should in Embedded E.164 format because some MGW does not recognise the Local format.

• For the remote A2EA address any of the four formats can be used• How to enter the A2EA, how to conclude the string (of 40 digits) and how many

digits are recognized by the systems, please see details in NED.• Note: What we call A2EA in RAN is AESA in the ATM world

How to plan the A2EA addresses

• A2EA addresses are used to route AAL2 signalling and traffic on Iub, Iu-CS & Iur.• For Iub A2EA addresses is generated automatically by the system during WBTS

commissioning and CoCo creation in RNC. It is also possible to give the numbering manually.

• When auto-addressing for NodeB is used the follwing rule is used to composite the address:

A2EA = “49” + 5 digits (WBTS_id) + 2 digits (WAM id) + 1 digit “0” (filler)For example, the A2EA for the WBTS id 12448 with WAM id 3 would be

4912448030

• The length of the digit sequence will be 40 in the system. The additional characters at the end of the digit sequence are filled with 0xF when the digit is stored to the system.

• For the A2EA address of the RNC and the related Core network elements the operator is pretty free in creation of the string after the digits of the AFI code

• For the DCC (AFI39) and ICD (AFI47) format also the next 4 digits cannot be freely chosen but depend on the network settings

What is needed to create Routing objects and digit analysis• Ensure that all needed ATM resources and cross connections

are correctly created (AAL2UD and MTP3SL VCCs), and that the SS7 signaling network is correctly configured.

• For Iur, each RNC is identified with its A2EA address• On the Iu-CS, the MGW is identified with its A2EA address• For Iub each WAM is identified with its A2EA address

(automatically created with CoCo Objects)• The following routing objects should be created:

– Digit Analysis Tree– AAL type 2 route– AAL2 endpoint– AAL2 endpoint group

With RAS06 there‘s a new feature named Flexible Iu. It is possible to connect each RNC to two different MGW. This is simply for redundancy to protect from

• outage of any Iu-CS interface

• failure on a MEGACO connection

• outage of the MGW itself

The interfaces and the MGW have to be planned and dimensioned accordingly.

Creating IP Static Routes for Iu-PS User Plane

• The routing of IP packets on Iu-PS is based on Static Routing Tables, and Inverse ATM ARP (InvATMARP) tables.

• When the ATM VCCs are connected between the RNC and the SGSN, the RNC enquires what IP address is at the other end of each VCC. When it receives this enquiry, the SGSN responds with the Interface address of the GPLC to which that VCC is connected. Now the RNC knows on which VCCs to send user data IP packets on the uplink.

For the GTPU this is the IP address of the GPLC interface (or loopback interface) to which the VCC is connected. This parameter is obligatory

Gateway IP Address

The route type for the static route to be created. It is not available for multiple default route configuration.PHY: A route that uses a physical address to reach its gateway. A physical route is always present in the unit it is configured. This is the default value.LOG: A route that uses a logical address to reach its gateway. The route follows the logical address if a switchover occurs.

Route Type

The length of the destination address net mask. This parameter indicates which units are to be included on the route.

Case C: OSPF on Iu-PS - Required parameters Note: The following material is considered as additional information and is not subject of this training anymore as it requires deep knowledge of IP-Planning and Routing Protocols

This example shows how to configure the Iu-PS interface between the RNC and SGSN using OSPF (Open Shortest Path First) for routing. When OSPF is in use and a link fails, the user plane traffic is automatically switched to the working link.

OSPF area parameters

• The OSPF area parameters do not become effective (written into the configuration file) until there is an interface which has the area attached to it.

• Unit type (GTPU) / Unit index / Unit group• Area identification:

– Specifies the area id for a new OSPF area. The area id is entered as a dotted-quad. The area id of 0.0.0.0 is reserved for the backbone. The IP network number of a subnetted network may be used as the area id. Range: Dotted-quad (i.e. [0-255].[0-255].[0-255].[0-255]).

• Stub area:– The stub area parameter block is inquired only if the area identification specified a non-backbone area.

The stub area parameter specifies an area in which there are no Autonomous System External (ASE) routes. ASE routes are routes to destinations external to the AS. A setting of yes indicates the area should be a stub, i.e. the external routing capability is disabled.

• Stub area route cost:– This parameter specifies the cost which is used when injecting a default route into the stub. This field is

displayed only if a new area is defined as a stub area. This parameter can also be called the stub default cost.

• Totally stubby area:– Specifies an area in which there are no ASE routes and summary routes. This field is displayed only if

a new area is defined as a stub area.

OSPF redistribute parameters

Unit type: – The type of the computer unit in which you want to configure the OSPF

redistribution information. The program provides a list of units from which to choose. Parameter is mandatory.

Unit index: – The index of the computer unit in which you want to configure the

OSPF redistribution information. The index is given in decimal form. The number of units determines the maximum value of the parameter. Those unit types, which also require a unit group number in the unit identification, the unit index is only given after the parameter unit group. Parameter is mandatory.

Redistribute type and identification: – it is possible to redistribute an interface (IF) or a static route (ST).

Metric: – it is possible to associate a metric to the route redistributed.

D. Configure interfaces for that area.


OSPF interface parameters (1)

• Unit type / Unit index / Unit group• Interface identification:

– The name of the interface is given as a character string, maximum 10 characters. The parameter is mandatory. The configured interfaces that can be used as an OSPF interface can be found with the QRA MML command.

• Area identification: – This parameter specifies the area id to which the interface will be attached. The

parameter is mandatory when configuring an OSFP interface. The area id is entered as a dotted-quad. The area id of 0.0.0.0 is reserved for the backbone. Range: Dotted-quad (i.e. [0-255].[0-255].[0-255].[0-255]).

• Hello interval: – This parameter specifies the length of time, in seconds, between hello packets that the

router sends on the interface. For a given link, this field must be the same on all routers or adjacencies will not form.

• Router dead interval: – This parameter specifies the number of seconds being unable to hear a router's hello

packets before the router declares the neighbour is down. Typically, the value of this field should be four times the size of the hello interval. For a given link, this field must be the same on all routers or adjacencies will not form.


OSPF interface parameters (2)

• OSPF cost:– This parameter specifies the weight of a given path in a route. The higher the cost, the less preferred the link. You may

explicitly override this in route redistribution. For example: to use one interface over another for routing paths, give one a higher cost.

• Election priority:– This parameter specifies the priority for becoming the designated router (DR) on this link. When two routers attached to

a network both attempt to become a designated router, the one with the highest priority wins. If there is currently an elected DR on the link, it will remain the DR regardless of the configured priority. This is to prevent changing the DR too often. This field is only relevant on a shared-media interface (Ethernet), as a DR is not elected on point-to-point type interfaces. A router with priority 0 is not eligible to become the designated router.

• Passive:– An interface that is put into passive mode will not send hello packets out of the given interface. This means no

adjacencies will be formed on the link. The purpose of this mode is to enable the network associated with the interface to be included in the intra-area route calculation as opposed to redistributing the network into OSPF and having it as an ASE. In passive mode, all interface configuration information, with the exception of the associated area and the cost, are ignored.

Y: suppressed hello packets / N: do not suppress hello packets (default)

• Authentication:– This parameter indicates what type of authentication scheme to use for a given OSPF interface. In general, routers on a

given link must agree on the authentication configuration in order to form neighbour adjacencies. This is used to guarantee that routing information is accepted only from trusted routers.

NONE: no authentication is used (default) / SIMPLE: simple password authentication is used / MD5: MD5 authentication method is used

• Password:– If the authentication type was selected as SIMPLE or MD5, then a password is required. With SIMPLE the password is

an ascii string of the length 1-8 characters. With the MD5 the password size is 1-16 characters.


OSPF parameters

• Unit type (GTPU) / Unit Index / Unit Group • Router identification:

– The router identification is given in form of an IP address. Router id specifies a number that uniquely defines the router in a routing domain. Selecting an existing IP address in the unit as the OSPF router id inherently makes it unique. Note: The router id of 0.0.0.0 can not be used as a router id, instead by giving the 0.0.0.0 as the value to the router id, the current router id is taken out of the use. It is recommended that you set the router id as opposed to relying on the system to pick one based on an IP address. This is recommended to prevent the router id from changing if the interface used for the router id goes down. Range: Dotted-quad (i.e. [0-255].[0-255].[0-255].[0-255]). Default: If no router ID is given then the router selects internally the highest interface address at the time that OSPF is enabled.

• rfc1583 compatibility: – This implementation of OSPF is based on RFC2178 which fixes some looping problems

in an earlier specification of OSPF. If this implementation will be running in an environment with OSPF implementations based on RFC1583 or earlier, this OSPF should be run in the compatibility mode. This will ensure backwards compatibility. Default: Enabled (Y).

• spf delay: – specifies the time (in seconds) to wait before recalculating the OSPF routing table after a

change in the topology. Default: 2 sec.• spf hold time:

– specifies the minimum time (in seconds) between recalculations of the OSPF routing table. Default: 5 sec.


OSPF Virtual Link Parameters

• If the router is a border router with no interfaces in the backbone area, it must configure a virtual link connecting it to the backbone area. The virtual link is effectively a tunnel across an adjacent non-backbone area whose endpoint must be any of the adjacent area's border routers that has an interface in the backbone area. – Unit type / Unit index / Unit group– Router identification:

This parameter specifies the router id of the remote endpoint of the virtual link. Parameter is mandatory.

– Transit area:This parameter specifies the area shared by the border router on which we are configuring the virtual link, and the router with an interface in the backbone area. Traffic between the endpoints of the virtual link will flow through this area. The transit area can't be a backbone area or a stub area. Parameter is mandatory.

– Hello interval– Router dead interval– Authentication

Password


OSPF network prefix parameters

• Unit type / Unit index / Unit group• Area identification• Network prefix:

– Any area can be configured with any number of address ranges. These ranges are used to potentially reduce the number of routing entries that a given area will emit into the backbone (and hence all) areas. If a given prefix aggregates a number of more specific prefixes within an area, then an address range can be configured and will be the only prefix advertised into the backbone. Care must be taken in configuring an address range that covers parts of a prefix that are not contained within the area.

• Network prefix mask length:– The mask length defines the mask length of the address range to be advertised.

• Network prefix restriction:– If an address range was marked restrict, then no advertisement will be injected

into the backbone. The default is yes. Y: summary LSA are advertised / N: no summary LSA are advertised


Summary Iu-PS

• Since release RAN04 it does not automatically require the migration from Static Routes to OSPF

• Planning OSPF for Iu-PS requires a very good knowledge about IP networks and Routing Protocols

• Loopback for GPLC and GTPU provides most possible safety from traffic loss

• Since SGSN Release 3 also MSP1+1 is possible for Iu-PS– Little delay but no loss of PDP context in case line or interface black out
