11、obile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) of the European Telecommunications Standards Institute (ETSI). This GTS specifieslnformation element mapping between Mobile Station - Base Station System (MS - BSS) and Base Station System - Mobile

12、-services Switching Centre (BSS - MSC) Signalling procedures and the Mobile Application Part (MAP) within the digital cellular telecommunications system (Phase 2/Phase 2+). GTS are produced by SMG to enable the GSM Phase 2+ specifications to become publicly available, prior to submission for the for

13、mal ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+ specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile communications. Subclause 4.5.2 has been mod

14、ified in this version 52.0. The contents of this GTS are subject to continuing work within SMG and may change following formal SMG approval. Should SMG modify the contents of this GTS it w ill then be republished by ETSI with an identifying change of release date and an increase in version number as

15、 follows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the specification; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. The specification from which this GTS has

16、been derived was originally based on CEPT documentation, hence the presentation of this GTS may not be entirely in accordance with the ETSI rules.

17、ical Specification is: i) to provide a detailed specification for the interworking between information elements contained in layer 3 messages sent on the MS-MSC interface (Call Control and Mob ility Management parts of GSM 04.08) and parameters contained in MAP services sent over the MSC-VLR interfa

18、ce (GSM 09.02) where the MSC acts as a transparent relay of information; i) to provide a detailed specification for the interworking between information elements contained in BSSMAP messages sent on the BSC-MSC interface (GSM 08.08) and parameters contained in MAP services sent over the MSC-VLR inte

19、rface (GSM 09.02) where the MSC acts as a transparent relay of information; iii) to provide a detailed specification for the interworking as in i) and i) above when the MSC also processes the information. Interworking for supplementary services is given in GSM 09.11. Interworking for the short messa

20、ge service is given in GSM 03.40 and GSM 04.11. Interworking between the call control signalling of GSM 04.08 and the PSTNIISDN is given in GSM 09.03, GSM 09.07 and GSM 09.08. Interworking between the A and E interfaces for inter-MSC handover signalling is given in GSM 09.07 and 09.08. 1.1 Normative

Page 9 GSM 09.10 version 5.2.0: November 1997 2 Classification of interworking cases 2.1 Transparent procedures The following MSC

30、 procedures require transparent mapping of BSSAP information elements into MAP parameters and vice versa (see GSM 09.02 for definitions and the use of the procedures): - update location area; - detach IMSI; - forward new TMSI; - provide IMSI; - obtain IMEI; - checkIMEI; - authenticate; - trace subsc

31、riber activity. 2.2 Non-transparent procedures Procedures in this class require processing in the MSC and information element mapping. These procedures include those related to: - outgoing call Set-up; - incoming call Set-up; - handover; - cipher mode setting. 3 Interworking in the MSC, Transparent

32、case 3.1 General When the MSC receives a forward message from the BSS (possibly forwarded transparently from the MS), it will invoke the desired MAP service and establish a cross reference between the BSSAP procedure and the MAP procedure in order to return the result of the operation to the BSS (wh

33、ich may forward it transparently to the MS. The cross reference is deleted when the MSC terminates the MAP procedu re. Positive or negative results of the MAP procedure are returned in the appropriate BSSAP message. The parameters of the forward BSSAP message are mapped by a one-to-one mapping into

34、the parameters of the MAP service. However, in some cases parameters received on the radio path may be suppressed at the MSC because they are related to another protocol entity, e.g. information related to RR-management may be included in MM-management messages. Similarly, parameters received in the

35、 (positive) MAP service response are mapped one-to-one into parameters of the corresponding backward BSSAP message. A negative outcome, as carried in various MAP services (MAP specific service response, MAP-U-ABORT, MAP-P-ABORT, MAP,-NOTICE and premature MAP-CLOSE, see GSM 09.02 for definitions) is

36、mapped into a cause value in the required backward BSSAP mess age. In this case several negative results of MAP may be mapped into the same BSSAP cause value, .e. without discrimination between these negative results. NOTE: For O ? M purposes, the MAP procedure entity in the MSC may require a more d

37、etailed overview of negative results than the MS.

The handover procedure

44、is normally triggered by BSS-A by sending a HANDOVER REQUIRED message on A-Interface to MSC-A. The invocation of the Basic Inter-MSC handover procedure is performed and controlled by MSC-A. The sending of the MAP Prepare-Handover request to MSC-B is triggered in MSC-A upon receipt of the HANDOVER RE

45、QUIRED message. For compatibility reason, the cell identity of the cell where the call is to be handed over in MSC-B area, provided in the HANDOVER REQUIRED message, is mapped into targetcellld MAP parameter and the HANDOVER REQUEST message is encapsulated in the bss-APDU MAP parameter of the Prepar

46、e-Handover MAP request. MSC-B can invoke another operation towards the VLR-B (allocation of the handover number described in GSM 09.02). Additionally, if tracing activity has been invoked, the trace related messages can be transferred on the E- Interface encapsulated in the bss-APDU MAP parameter of

47、 the Prepare-Handover Request. lf transferred, one complete trace related message at a time shall be included in the bss-APDU MAP parameter after the HANDOVER REQUEST message.
