The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of
22、 the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document
23、under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. ETSI ETSI TS 122 067 V14.0.0 (2017-03)53GPP TS 22.067 version 14.0.0 Release 141 Scope The present document specifies the stage 1 description of the enhanced
24、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. Pre-emption involves the seizing of resources, which are in use by a call of a lower preceden
25、ce, 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 precedence. The eMLPP service is provided as a network operators option to a domain of a network. The do
26、main 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 the domain with all or some mobile stations having a respective subscription assigning precedenc
27、e 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 service subscribers and users point of view, in particular: - the procedure for normal operatio
28、n 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) requirements, but makes reference to the appropriate specifications. The present document is a
29、pplicable 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 outside the scope of the present document. 2 References The following documents contain provisions wh
30、ich, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply.

34、-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 interaction of the user. calling subscriber: Service subscriber which invokes the eMLPP service. networ
35、k 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 priority associated with a call. service provider: Entity which offers the eMLPP service for subscrip
36、tion. 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 subscribe to this service. 3.2 Abbreviations For the purposes of the present document, the fol
37、lowing 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-emption service (eMLPP) provides different levels of precedence for call set-up and for call c
38、ontinuity 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 service provider, based on the subscribers need. The subscriber may select a precedence level up
39、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 calls or the network related service configurations for specific voice broadcast or voice group cal
40、l 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. in the domain of one MSC. The other five priority levels are offered for subscription and may
41、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 defined as follows: A (highest, for network internal use). B (for network internal use or, optionally
42、, for subscription). 0 (for subscription). 1 (for subscription). 2 (for subscription). 3 (for subscription). ETSI ETSI TS 122 067 V14.0.0 (2017-03)73GPP TS 22.067 version 14.0.0 Release 144 (lowest, for subscription). Levels A and B shall be mapped to level 0 for priority treatment outside of the MS
43、C 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 subscriber. - If the user has no eMLPP subscription, the call shall have a default priority level define
44、d 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 by registration. - Mobile terminated calls: - The priority level depends on the calling party.
45、 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, then the call shall be treated in the terminating mobile network with a default priority level de
46、fined 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 is an ISDN MLPP call, the call shall be treated with the priority level provided by the interfac
47、ing 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 calls. - Mobile-to-mobile calls in one network: The priority shall be treated for the calling subsc
48、riber 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 voice group call, when there is only a link between the calling mobile station and the network, th
49、e 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 classes of set-up time performance and examples of the call set-up times are: - class 1 fast set
