15、le communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) of the European Telecommunications Standards Institute (ETSI). This GTS provides a mechanism giving reliable transfer of signalling mess ages within the digital cellular telecommunications system (Pha
16、se 2/Phase 2+). 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 follows: Ve

18、age 7 GSM 03.09 version 5.1 .O: August 1997 1 scope This Global System for Mobile communications Technical Specification (GTS) contains a detailed 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
19、 that the connection to the Mobile Station (MS) is maintained as it moves from one Base Station System (BSS) area to another. This specification considers the following two cases: i) Handover between Base Stations connected to the same MSC, this is termed an Intra-MSC handover. i) Handover between B
20、ase 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 procedure, where the MS is handed over from a controlling MSC (MSC-A) to another MSC (MSC-B); b) the Subsequent Inter-MSC Ha
21、ndover 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 cases i) and i) the same procedures as defined in the GSM 08.08 and the GSM 04.08 shall be used on the A-interface and on th
22、e 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 (MAP), GSM 09.02. The split in functionality between the BSS and MSC is descri bed in the GSM 08 series of Technical Specifica
23、tions. The interworkin between the GSM 09.02 protocol and the GSM 08.08 protocol is described in the Handovers which take place on the same MSC are termed Intra-MSC handovers; this includes both Inter- BSS and Intra-BSS handovers. GSM 09.1 O Tec a nical Specification. This technical specification al
24、so covers the requirements for handover in ongoing voice group calls, directed retry and the handover without a circuit connection between MSC-A and MSC-B. This technical specification does not consider the case of handovers between radio channels on the same BSS (Intra- BSS handover) or the handove
25、r of packet radio services. For voice broadcast calls, the speaker uses normal point-to-point handover procedures, whilst the listeners use idle mode cell reselection procedures, as for the voice group call listeners. Inter-MSC hand-over imposes a few limitations on the system. After inter-MSC hand-
26、over: - call re-establishment is not supported. The list of GSM 08.08 features supported during and after Inter-MSC handover is given in GSM 09.08. 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
27、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 this 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
28、 of technical specifications. The primitive names are only intended to be indicative of their use in this document.
