15、00855 0105677 468 I Page 5 GSM 03.09 Version 5.0.0: May 1996 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS provid
16、es a mechanism giving reliable transfer of signalling messages within the digital cellular telecommunications system (Phase 2Phase 2+). This GTS is a TC-SMG approved GSM technical specification version 5, which contains GSM Phase 2+ enhancementdfeatures to the version 4 GSM technical specification.
17、The ETS from which this Phase 2+ GTS has evolved is Phase 2 GSM 03.09 version 4.6.0. GTS are produced by TC-SMG to enable the GSM Phase 2 + specifications to become publicly available, prior to submission for the formal ETSI standards approval procedure to become European Telecommunications Standard
18、s (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. The contents of this GTS are subject to continuing work within TC-SMG and may change following formal TC-SMG ap
19、proval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the specifica
20、tion; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. NOTE: TC-SMG has produced documents which give the technical specifications for the implementation of the digital cellular telecommunications system. Historically, these doc
21、uments have been identified as GSM Technical Specifications (GSM-TSs). These TSs may have subsequently become I-ETSs (Phase I), or ETSsIETSI Technical Reports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give the technical specifications for the implementation of Phase 2+ enhancemen
22、ts of the digital cellular telecommunications system. These version 5.x.x GSM Technical Specifications may be referred to as GISS.

24、tailed description of the handover procedures to be used in GSM PLMNs. The purpose of the handover procedures, as described in this specification, are to ensure that the connection to the MS is maintained as it moves from one BSS area to another. This specification considers the following two cases:
25、 i) Handover between Base Stations connected to the same MSC, this is termed an Intra-MSC handover. i) Handover between Base Stations connected to different MSCs, this is termed an Inter-MSC handover. This category can be sub-divided into three further procedures: a) the Basic Inter-MSC Handover pro
26、cedure, where the MS is handed over from a controlling MSC (MSC-A) to another MSC (MSC-B); b) the Subsequent Inter-MSC Handover procedure, where the MS is handed over from MSC-B to a third MSC (MSC-B); c) the Subsequent Inter-MSC handback, where the MS is handed back from MSC-B to MSC-A. In both cas
27、es i) and i) the same procedures as defined in the TS GSM 08.08 and the TS GSM 04.08 shall be used on the A-interface and on the Radio Interface, respectively. In case i) the handover procedures shall transport the A-interface messages between MSC-A and MSC-B described in the Mobile Application Part
28、 (MAP), Technical Specification GSM 09.02. The split in functionality between the BSS and MSC is described in the GSM 08 series of Technical Specifications. The interworking between the GSM 09.02 protocol and the GSM 08.08 protocol is described in the GSM 09.1 O Technical Specification. Handovers wh
29、ich take place on the same MSC are termed Intra-MSC handovers; this includes both Inter- BSS and Intra-BSS handovers. This technical specification also covers the requirements for handover in ongoing voice group calls, directed retry and the handover without a circuit connection between MSC-A and MS
30、C-B. This technical specification does not consider the case of handovers between radio channels on the same BSS (Intra- BSS handover) or the handover of packet radio services. For voice broadcast calls, the speaker uses normal point-to-point handover procedures, whilst the listeners use idle mode c
31、ell reselection procedures, as for the voice group call listeners. Inter-MSC hand-over imposes a few limitations on the system. After inter-MSC hand-over: - call re-establishment is not supported. The list of GSM 08.08 features supported during and after Inter-MSC handover is given in TS GSM 09.08.
32、In the Inter-MSC handover case, the interworking between a Phase 1 BSSMAP protocol possibly used by one MSC and the Phase 2 BSSMAP protocol used in the Phase 2 MAP protocol on the E-interface is performed by this MSC. NOTE: The message primitive names used in the SDL diagrams and message flows in th
33、is technical specification do not represent the actual messages specified in the GSM 04 and GSM 08 series or the services specified in the GSM O9 series of technical specifications. The primitive names are only intended to be indicative of their use in this document. COPYRIGHT European Telecommunica
