10 9 TS V3.0.0 ( ) 4 The entities and interfaces within the mobile network utilising the 4.1 The entities of the mobile system The functional entities related to the are described below. The description of each entity is detailed in 3G TS ( stage2 specification). The other functional entities described in the present document (e.g. MSC, VLR, and HLR) are specified in 3G TS The Gateway location Register (). - The Intermediate MSC (IM-MSC). - The Intermediate GSN (IM-GSN). 4.2 The Interfaces within the mobile services The Interfaces related to the are described below. The description of each interface is detailed in 3G TS ( stage2 specification). - Interface between the HLR and the. - Interface between the VLR and the. - Interface between the MSC and the IM_MSC. - Interface between the SGSN and the. - Interface between the MSC and the. - Interface between the and the IM_GSN. 5 Overload and compatibility overview 5.1 Overload control for MAP entities The VLR and SGSN see the as an HLR, and the HLR sees the as a VLR or a SGSN. Therefore the shall behave like mobile entity as which the is regarded. If overload of the is detected, the responder may ignore uests for certain MAP operations (see tables 5.1/1, 5.1/2 and 5.1/3 in 3G TS ). The decision as to which MAP Operations may be ignored is made by the MAP service provider and is based upon the priority of the application context. 5.2 Compatibility A version negotiation mechanism based on the use of an application-context-name is used to negotiate the protocol version used between two entities for supporting a MAP-user signalling procedure. The description of the version negotiation mechanism is detailed in 3G TS

11 10 TS V3.0.0 ( ) 6 Requirements concerning the use of SCCP and TC 6.1 Use of SCCP The Mobile Application Part makes use of the services offered by the Signalling Connection Control Part of signalling System No. 7. CCITT Blue Book or ITU-T (03/93) Recommendations Q.711 to Q.716 should be consulted for the full specification of SCCP. In North America (World Zone 1) the national version of SCCP is used as specified in ANSI T SCCP Class MAP will only make use of the connectionless classes (0 or 1) of the SCCP Sub-System Number (SSN) The Application Entities (AEs) defined for MAP consist of several Application Service Elements (ASEs) and are addressed by sub-system numbers (SSNs). The SSN for MAP are specified in 3G TS [1]. The specific SSN is not needed for the, IM_MSC, and IM_GSN SCCP addressing Introduction The format and coding of address parameters carried by SCCP are detailed in 3G TS The following subclauses describe the method of SCCP addressing appropriate for each entity both for the simple intra- PLMN case and where an inter-plmn communication is uired. The following entities are considered for the additionally: - the Gateway location Register (); - the Intermediate Mobile-services Switching Centre (IM_MSC); - the Intermediate GPRS Support Node (IM_GSN) The Gateway Location Register () Addressed by the VLR In the network utilising the, when an MS that belongs to other PLMN registers in a VLR/SGSN, the VLR/SGSN sees the as the MS's HLR. When initiating the update location dialogues, the VLR is able to address the based on the SPC of the because of intra-plmn signalling. And the VLR can address the based on an E.214 Mobile Global Title originally derived by the VLR from the IMSI (when CCITT or ITU-T SCCP is used), or an E.212 number originally derived from IMSI (when ANSI SCCP is used, an IMSI). When answering with Global Title to the VLR, the shall insert its E.164 address in the Calling Party Address of the SCCP message containing the first responding CONTINUE message. After that, the VLR can address the based on an E.164 address Addressed by the HLR When a location updating dialogue initiated by a has been successfully completed, the HLR sees the as the VLR. When initiating dialogues towards the VLR, the routeing information used by the HLR is derived from the E.164 VLR number received as a parameter of the MAP message initiating the update location dialogue, but in reality the HLR addresses the using the VLR number.

12 11 TS V3.0.0 ( ) Addressed by the GMSC In the case that the MS is served by the SGSN in the network utilising the, the GMSC sees the as the SGSN. When the GMSC initiates dialogues towards the SGSN the SGSN (MAP) SSN (See 3G TS ) shall be included in the called party address. The routeing information used by the GMSC is derived from the E.164 SGSN number received as a parameter of the MAP message initiating the forward short message procedure. But in reality the GMSC addresses the using the SGSN number Addressed by the IM-GSN In the network utilising the, the IM-GSN initiates the GPRS location information retrieval to the. The IM-GSN must have the value of the address beforehand The Intermediate MSC (IM_MSC) Addressed by the GMSC When a short message for CS has to be routed to an MS, the GMSC addresses the MSC by an MSC identity received from the HLR that complies with E.164 rules. But in reality the GMSC addresses the IM-MSC in the network utilising the Addressed by the GMLC When a location uest for a particular MS needs to be sent to the MS's VMSC, the GMLC addresses the MSC using an E.164 address received from the MS's HLR. But in reality the GMLC addresses the IM-MSC in the network utilising the The Intermediate GSN (IM_GSN) The IM-GSN provides routing of the Network-Requested PDP Context activation. If a Network-Requested PDP Context activation fails, the will alert the IM-GSN when the subscriber becomes reachable. The will use the E.164 IM-GSN number received as parameter of the MAP message reporting the failure Summary table The following table summarises the SCCP address used for invoke operations. As a principle, within a PLMN either an SPC or a GT may be used (network operation option), whereas when addressing an entity outside the PLMN the GT must be used. The address type mentioned in the table (e.g. MSISDN) is used as GT or to derive the SPC. For a response, the originating address passed in the invoke message is used as SCCP Called Party Address. For extra-plmn addressing the own E.164 entity address is used as SCCP Calling Party Address; for intra-plmn addressing an SPC derived from the entity number may be used instead. When using an SPC, the SPC may be taken directly from MTP.

The result can be an SPC or an E.214 Mobile Global Title if CCITT or ITU-T SCCP is used, or IMSI itself if ANSI SCCP is used (ANSI SCCP is used in World Zone 1). When continuing the established update location dialogue (as with any other dialogue) the VLR must derive the routeing information towards the HLR from the Calling Party Address received with the first responding CONTINUE message until the dialogue terminating message is received. For transactions invoked by the VLR after update location completion, the VLR may derive the information for addressing the HLR from addresses received in the course of the update location procedure (MSISDN or HLR number) or from the IMSI. When invoking the Restore Data procedure and an authentication information retrieval from the HLR preceding it, the VLR must derive the information for addressing the HLR from the address information received in association with the roaming number uest. This may be either the IMSI received as a parameter of the MAP message uesting the Roaming Number or the Calling Party Address associated with the MAP message uesting the Roaming Number. From VLR in, as for T (address type) only HLR Number is used. VLR and HLR are because only the thing that is belonging to same PLMN is thought.

The processes will be addressed by SCCP SSN (VLR or HLR) and the Application Context. The processes in the interact with the processes in the VLR or HLR defined in The followings show the relations between the protocol processes in the and the processes in the other node. Process Update Location (VLR-): - Initiator: Update_Location_Area_VLR or Update_Location_HLR; - Responder: Update_Location_.

A Location Management Co-ordinator in the co-ordinates the two protocol processes "Update_Location_" (subclause ) and "RESTORE_DATA_" (subclause 19.2) that are addressed by the same application context. On receipt of a dialogue uest for the Location Management Application Context, the location Management_Coordinator_ will: - Terminate the process in case of parameter problems; or - Revert to MAP version Vr protocol if the VLR uests version Vr protocol; or - Continue as described in the following, if the dialogue is accepted. The protocol process is created depending on the first primitive received from the MAP service provider within this dialogue: - Update_Location_ if the primitive is a UPDATE_LOCATION indication. - RESTORE_DATA_ if the primitive is a RESTORE_DATA indication.

26 25 TS V3.0.0 ( ) If a NOTICE indication is received instead, the dialogue towards the VLR is terminated and the process returns to idle state. After creation of the protocol process the service primitive received from the MAP service-provider is passed to the protocol process. Henceforth, the co-ordinator will relay all service primitives from MAP service-provider to the MAP service-user and vice versa, until a uest or indication for dialogue termination is received. This last primitive will be relayed, too, before the Co-ordinator process returns to idle state.

Responder: Purge_MS_HLR Location updating General This location updating procedure is used to update the location information held in the network. If the is located between the VLR and the HLR, the UPDATE_LOCATION service is invoked towards the whose identity is contained in the VLR table. When the receives a UPDATE_LOCATION indication, it determines whether it invokes the UPDATE_LOCATION service towards the HLR, and invokes it if necessary.

41 40 TS V3.0.0 ( ) Location Cancellation General The purpose of this process is to delete a subscriber's record from a previous /VLR/SGSN after she has registered with a new /VLR/SGSN. The procedure may also be used if the subscriber's record is to be deleted for other operator determined purposes. Location cancellation can be used to enforce location updating including updating of subscriber data in the VLR or in the SGSN at the next subscriber access. In all cases, the process is performed independently of the invoking process (e.g. Location Updating). If is located between the VLR or the SGSN and the HLR, the CANCEL_LOCATION service is invoked towards the whose identity is contained in the HLR table. NOTE: The service shown in dotted lines indicates the trigger provided by other MAP signalling. Figure /1: Interface and services for Location Cancellation NOTE: The service shown in dotted lines indicates the trigger provided by other MAP signalling. Figure /2: Interface and services for Location Cancellation in GPRS Additionally, The CANCEL_LOCATION service is invoked when the that stores the subscriber's record receives a UPDATE_LOCATION indication from a VLR other than that stored in its table for this subscriber. Also the CANCEL_LOCATION service is invoked when the that stores the subscriber's record a UPDATE_GPRS_LOCATION indication from a SGSN other than stored in its table for this subscriber. The CANCEL_LOCATION service is in any case invoked towards the VLR or the SGSN whose identity is contained in the HLR table.
