ETSIEN 300 947 V6.0.1 (1999-09)5(GSM 04.67 version 6.0.1 Release 1997)1ScopeThe present document specifies the procedures used at the radio interface (Reference point Um as defined inGSM 04.02) for normal operation, invocation, registration and interrogation of the enhanced Multi-Level Precedenceand Pre-emption Service (eMLPP) supplementary service. Provision and withdrawal of supplementary services is anadministrative matter between the mobile subscriber and the service provider and cause no signalling on the radiointerface.In GSM 04.10 the general aspects of the specification of supplementary services at the layer 3 radio interface are given.GSM 04.80 specifies the formats and coding for the supplementary services.Definitions and descriptions of supplementary services are given in GSM 02.04 and GSM 02.8x and 02.9x-series.GSM 02.67 is related specially to eMLPP.Technical realization of supplementary services is described in GSM 03.11 and GSM 03.8x and 03.9x-series.GSM 03.67 is related specially to eMLPP.The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interfaceare defined in GSM 04.07 and GSM 04.08.2ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, the latest version applies.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.· For this Release 1997 document, references to GSM documents are for Release 1997 versions (version 6.x.y).[1]GSM 01.04: "Digital cellular telecommunications system (Phase 2+); Abbreviations andacronyms".[2]GSM 02.04: "Digital cellular telecommunications system (Phase 2+); General on supplementaryservices".[3]GSM 02.67: "Digital cellular telecommunications system (Phase 2+); enhanced Multi-LevelPrecedence and Pre-emption service (eMLPP) - Stage 1".[4]GSM 02.81: "Digital cellular telecommunications system (Phase 2+); Line identificationsupplementary services - Stage 1".[5]GSM 02.82: "Digital cellular telecommunications system (Phase 2+); Call Forwarding (CF)supplementary services - Stage 1".[6]GSM 02.83: "Digital cellular telecommunications system (Phase 2+); Call Waiting (CW) and CallHold (HOLD) supplementary services - Stage 1".[7]GSM 02.84: "Digital cellular telecommunications system (Phase 2+); MultiParty (MPTY)supplementary services - Stage 1".[8]GSM 02.85: "Digital cellular telecommunications system (Phase 2+); Closed User Group (CUG)supplementary services - Stage 1".SIST EN 300 947 V6.0.1:2003
