ETSIEN 300 924 V6.0.1 (1999-09)5GSM 02.67 version 6.0.1 Release 19971ScopeThe present document specifies the stage 1 description of the enhanced Multi-Level Precedence and Pre-emptionService (eMLPP). This service has two parts: precedence and pre-emption. Precedence involves assigning a prioritylevel to a call in combination with fast call set-up. Pre-emption involves the seizing of resources, which are in use by acall of a lower precedence, by a higher level precedence call in the absence of idle resources. Pre-emption can alsoinvolve the disconnection of an on-going call of lower precedence to accept an incoming call of higher precedence.The eMLPP service is provided as a network operator's option to a domain of a network. The domain can be the wholenetwork or a subset of the network. The eMLPP service applies to all network resources in the domain that is incommon use. The eMLPP service is applicable to all mobile stations in the domain with all or some mobile stationshaving a respective subscription assigning precedence according to the eMLPP service.eMLPP is a supplementary service and shall be provided to a subscriber for all basic services subscribed to and forwhich eMLPP applies.NOTE:It is under study whether normal GSM Phase 2 Mobile Stations will be able to be used for this service.The service is described from the service subscriber's and user's point of view, in particular:-the procedure for normal operation with successful outcome;-the action to be taken in exceptional circumstances;-the interaction with other GSM services and features.The present document does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to theappropriate Global System for Mobile communications (GSM) specifications.The present document is applicable to teleservices 1x and 6x and to all bearer services used in a mobile networkaccording to the digital cellular telecommunications system GSM if eMLPP is provided. Any interaction with otherservices and/or networks not dealt with in clauses 8 or 9 are outside the scope of the present document.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 02.24: "Digital cellular telecommunications system (Phase 2+); Description of ChargeAdvice Information (CAI)".[4]GSM 02.40: "Digital cellular telecommunications system (Phase 2+); Procedures for call progressindications".SIST EN 300 924 V6.0.1:2003

The subscriber may select a precedence level up to and including the maximum precedencelevel subscribed to, on a per call basis.There are at maximum 7 priority levels. The two highest levels are reserved for network internal use, e.g. foremergency calls or the network related service configurations for specific voice broadcast or voice group callservices. These two levels can only be used locally, i.e. in the domain of one MSC. The other five priority levelsare offered for subscription and can be applied globally, e.g. on inter switch trunks, if supported by all relatednetwork elements, and also for interworking with ISDN networks providing the MLPP service.SIST EN 300 924 V6.0.1:2003
