4 This GTS specifies the layer 3 procedures used on the BSS to MSC interface for control of GSM serviceswithin the Digital cellular telecommunications system (Phase 2/Phase 2+).This GTS is a TC-SMG approved GSM technical specification Version 5, which contains GSM Phase 2+enhancements/features to the Version 4 GSM technical specification. The ETS from which this Phase 2+GTS has evolved is Phase 2 GSM ETS 300 590 Edition 4 (GSM Version ).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 EuropeanTelecommunications 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 contents of this GTS are subject to continuing work within TC-SMG and may change following formalTC-SMG approval.

5 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 :ythe third digit is incremented when editorial only changes have been incorporated in thespecification;xthe second digit is incremented for all other types of changes, technical enhancements,corrections, updates, is made within this TS to GSM-TSs (note).NOTE:TC-SMG has produced documents which give the technical specifications for theimplementation of the Digital cellular telecommunications system. Historically, thesedocuments have been identified as GSM Technical Specifications (GSM-TSs). TheseTSs may have subsequently become I-ETSs (Phase 1), or ETSs/ETSI TechnicalReports (ETRs) (Phase 2).

6 TC-SMG has also produced ETSI GSM TSs which give thetechnical specifications for the implementation of Phase 2+ enhancements of the digitalcellular telecommunications system. These Version GSM Technical Specificationsmay be referred to as 8 GSM Version March 1996 Blank pagePage 9 GSM Version March 19961 ScopeThis Global System for Mobile communications Technical Specification (GTS) specifies the layer 3procedures used on the BSS to MSC interface for control of GSM the purposes of call control and mobility management, messages are not interpreted at the BaseStation System (BSS) which acts as a relay function. These messages and procedures are documented inTechnical Specification GSM , the only relevant issues covering these messages in this TechnicalSpecification are those concerned with error conditions at the interface, and the headers that are requiredfor the correct addressing of the messages.

7 This is specified in more detail in Technical Specification functional split between MSC and BSS is defined in Technical Specification GSM and statesthat the BSS is responsible for local radio resource allocation and in order to support this the requiredprocedures between BSS and MSC are defined in detail in this Technical Specification GSM also states that the BSS is responsible for the scheduling of allCCCH/BCCH messages and therefore some procedures for providing the BSS with the necessaryinformation to be passed on these channels for individual calls ( paging) are defined in this TechnicalSpecification, but the scheduling is not interface and consequently these layer 3 procedures are designed to support BSSs providing one ormore referencesThis GTS incorporates by dated and undated reference, provisions from other publications.
