24、3.0.0 Release 131 Scope The present document specifies the stage 1 description of the enhanced Multi-Level Precedence and Pre-emption Service (eMLPP). This service has two parts: precedence and pre-emption. Precedence involves assigning a priority level to a call in combination with fast call set-up
25、. Pre-emption involves the seizing of resources, which are in use by a call of a lower precedence, by a higher level precedence call in the absence of idle resources. Pre-emption can also involve the disconnection of an on-going call of lower precedence to accept an incoming call of higher precedenc
26、e. The eMLPP service is provided as a network operators option to a domain of a network. The domain can be the whole network or a subset of the network. The eMLPP service applies to all network resources in the domain that is in common use. The eMLPP service is applicable to all mobile stations in t
27、he domain with all or some mobile stations having 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 for which eMLPP applies. The service is described from the
28、service subscribers and users 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 services and features. The present document does not deal with the Man-Machine Interface (MMI)
29、 requirements, but makes reference to the appropriate specifications. The present document is applicable to teleservices 1x and 6x and to all bearer services used in a mobile network if eMLPP is provided. Any interaction with other services and/or networks not dealt with in clauses 8 or 9 are outsid

34、1 Definitions For the purposes of the present document, the following definitions apply: called-party pre-emption: Termination of a call to a particular user when a higher priority call is directed towards that specific user. Called party pre-emption is decided by the User Equipment without interact
35、ion of the user. calling subscriber: Service subscriber which invokes the eMLPP service. network operator: Entity which provides the network operating elements and resources for the execution of the enhanced Multi-Level Precedence and Pre-emption service (eMLPP). precedence: Precedence is the priori
36、ty associated with a call. service provider: Entity which offers the eMLPP service for subscription. The network operator may be the service provider. service subscriber: Mobile subscriber which subscribes to the eMLPP service. In principle, if a network provides eMLPP service, all users are able to
37、 subscribe to this service. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply, in addition to those listed in GSM 01.04 and 3GPP TR 21.905 1: eMLPP enhanced Multi-Level Precedence and Pre-emption 4 Description a) The enhanced Multi-Level Precedence and Pre
38、-emption service (eMLPP) provides different levels of precedence for call set-up and for call continuity in case of handover. eMLPP shall be applicable also in case of roaming if supported by the related networks. The maximum precedence level of a subscriber is set at the subscription time by the se
39、rvice provider, based on the subscribers need. The subscriber may select a precedence level up to and including the maximum precedence level subscribed to, on a per call basis. There are at maximum 7 priority levels. The highest level (A) is reserved for network internal use, e.g. for emergency call
40、s or the network related service configurations for specific voice broadcast or voice group call services. The second highest level (B) may be used for network internal use or, optionally, depending on regional requirements, for subscription. These two levels (A and B) may only be used locally, i.e.
41、 in the domain of one MSC. The other five priority levels are offered for subscription and may be applied globally, e.g. on inter switch trunks, if supported by all related network elements, and also for interworking with ISDN networks providing the MLPP service. The seven priority levels are define
42、d as follows: A (highest, for network internal use). B (for network internal use or, optionally, for subscription). 0 (for subscription). 1 (for subscription). 2 (for subscription). 3 (for subscription). ETSI ETSI TS 122 067 V13.0.0 (2016-01)73GPP TS 22.067 version 13.0.0 Release 134 (lowest, for su
43、bscription). Levels A and B shall be mapped to level 0 for priority treatment outside of the MSC area in which they are applied. b) Priorities shall be treated in the network as defined for the following call scenarios: - Mobile originated calls: - The priority level depends on the calling subscribe
44、r. - If the user has no eMLPP subscription, the call shall have a default priority level defined in the network. - If the user has an eMLPP subscription, the call shall have the priority level selected by the user at set-up or the priority level predefined by the subscriber as default priority level
45、 by registration. - Mobile terminated calls: - The priority level depends on the calling party. For this, interworking with the ISDN MLPP (Multi-Level Precedence and Pre-emption) service is required. - If the call is not an ISDN MLPP call, i.e. no priority level is received for the calling party, th
46、en the call shall be treated in the terminating mobile network with a default priority level defined in the terminating mobile network, or as an operator option may be treated with the priority level predefined by the called party subscriber as default priority level by registration. - If the call i
47、s an ISDN MLPP call, the call shall be treated with the priority level provided by the interfacing network. - Mobile-to-mobile calls in case of roaming: The priority shall be treated for the calling subscriber as for mobile originated calls and for the called subscriber as for mobile terminated call
48、s. - Mobile-to-mobile calls in one network: The priority shall be treated for the calling subscriber as for mobile originated calls and for the called subscriber as for mobile terminated calls. - Voice broadcast (VBS) and voice group calls (VGCS): At the first instances of the voice broadcast or voi
49、ce group call, when there is only a link between the calling mobile station and the network, the call shall be treated at the defined priority level of this voice broadcast or voice group call if this information is available. If the information is not available the call shall be treated as defined for mobile originated calls. Then, for the set-up of the voice broadcast or voice group call links in the related cells, the call shall have the priority level as defined for this voice broadcast or voice group call in the network. c) There are three c
