Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee of the European Telecommunications Standards Institute (ETSI).
38、This GTS specifies the layer 3 procedures used on the Base Station System (BSS) to Mobile-services Switching Centre (MSC) interface for control of GSM services within the digital cellular telecommunications system. The contents of this GTS are subject to continuing work within SMG and may change fol
39、lowing formal SMG approval. Should 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: 5 indicates GSM Phase 2+ Release 1996; x the second digit is incremented for all c
40、hanges of substance, .e. technical enhancements, corrections, updates, etc. y the third digit is incremented when editorial only changes have been incorporated in the specif ication.

41、ne 2000 1 Scope This Global System for Mobile communications Technical Specification (GTS) specifies the layer 3 procedures used on the Base Station System (BSS) to Mobile-services Switching Centre (MSC) interface for control of GSM services. For the purposes of call control and mobility management,
42、 messages are not interpreted at the Base Station System (BSS) which acts as a relay function. These messages and procedures are documented in GSM 04.08, the only relevant issues covering these messages in this GTS are those concerned with error conditions at the interface, and the headers that are
43、required for the correct addressing of the messages. This is specified in more detail in GSM 08.06. The functional split between MSC and BSS is defined in GSM 08.02 and states that the BSS is responsible for local radio resource allocation and in order to support this the required procedures between
44、 BSS and MSC are defined in detail in this Technical Specification. GSM 08.02 also states that the BSS is responsible for the scheduling of all CCCH/BCCH messages and therefore some procedures for providing the BSS with the necessary information to be passed on these channels for individual calls (.
45、e. paging) are defined in this Technical Specification, but the scheduling is not discussed. This interface and consequently these layer 3 procedures are designed to support BSSs providing one or more cells. 1.1 Normative references This GTS incorporates by dated and undated reference, provisions fr
