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 the present document,
21、 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 under change control.
22、y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The response to emergency situations (e.g., floods, hurricanes, ea
23、rthquakes, terrorist attacks) depends on the communication capabilities of public networks. In most cases, emergency responders use private radio systems to aid in the logistics of providing critically needed restoration services. However, certain government and emergency management officials and ot
24、her authorised users have to rely on public network services when the communication capability of the serving network may be impaired, for example due to congestion or partial network infrastructure outages, perhaps due to a direct or indirect result of the emergency situation. Multimedia Priority S
25、ervice, supported by the 3GPP system set of services and features, is one element creating the ability to deliver calls or complete sessions of a high priority nature from mobile to mobile networks, mobile to fixed networks, and fixed to mobile networks.

Priority Treatment: Refers to mechanisms and features that increase the success rate for MPS session invocation, establishment and maintenance until release. Service User: An indiv
33、idual authorized to use MPS and who has been granted a user priority level assignment by a regional/national authority (i.e., an agency authorised to issue priority assignments), and has a subscription to a mobile network operator that supports the MPS feature.

35、MPS Multimedia Priority Service 4 General description MPS provides priority treatment to increase the probability of an authorized Service Users Voice, Video, and Data communication session being successful. Some form of priority treatment is applied to the MPS invocation and session establishment,
36、and continues to be applied until the MPS session is released. The priority treatment may be applied before the invocation if a greater probability of success in receiving, recognizing, and processing the invocation is needed. MPS allows qualified and authorized users to obtain priority access to th
37、e next available radio channel on a priority basis before other PLMN users, during situations when PLMN congestion is blocking session establishment attempts. In addition, MPS supports priority sessions on an “end-to-end“ priority basis. MPS is intended to be utilised for Voice, Video, and Data bear
38、er services in the Packet-switched (PS) domain and the IP Multimedia Subsystem (IMS). It also involves priority transitioning of MPS service (e.g., Voice) to the CS domain when the network does not support the requested service in the PS domain. MPS Voice, Video and Data sessions are based on provid
39、ing priority treatment to the corresponding commercial services offered to the public. MPS includes network functions that fall into the following broad categories: Service Invocation: The process to recognize and identify a request for an MPS session. A MPS Service Provider network recognizes an MP
40、S invocation based on the presence of an MPS-unique identifier entered by the originating Service User in the service request received by the network from the UE, or based on the subscription profile of the originating UE, or as a regional/operator option the subscription profile of the terminating
41、UE. NOTE: The option related to “subscription profile of the terminating UE” may not involve end-to-end priority because this option is based on providing priority only in the terminating network based on the terminating UE subscription profile. Authorization: The process to verify that a Service Us
42、er is authorized for MPS. This includes capabilities to verify authorization to receive priority treatment in the radio access network and to access the MPS application service (MPS Voice, Video, and Data). End-to-End Priority Treatment: The process of providing priority treatment in all parts of th
43、e path, from one endpoint to the other endpoint(s). End-to-end priority treatment includes priority treatment by all MPS capable networks involved in the MPS session path, the origination network and the termination network as well as any transit networks in between. Invocation-to-Release Priority T
44、reatment: The process of providing priority treatment to all phases of a session, from invocation until release, including all steps in between. The combination of End-to-End Priority Treatment and Invocation-to-Release Priority Treatment includes both pre- and post-authorization treatment and inclu
45、des the following aspects: 1) Priority processing of the Service Users MPS invocation, 2) Admission control and allocation of network resources (including bearer resources) in origination, termination, and transit networks, including handovers, 3) Transport of signaling and media packets, 4) Priorit
46、y processing within EPS and CN, and 5) Processing of the Service Users release of an MPS service session. ETSI ETSI TS 122 153 V14.4.0 (2017-05)73GPP TS 22.153 version 14.4.0 Release 14Network Interconnection and Protocol Interworking: A Service Users MPS invocation and session establishment will in
47、volve transport and processing, and the end-to-end signaling and media path may traverse multiple MPS Service Provider networks. These end-to-end cases include, but are not limited to: 1) LTE-to-LTE for voice, video, and data services, including signaling for call/session establishment and media; 2)
48、 LTE interworking with the CS domain, including a) calls originated in the CS domain and terminated in LTE, and b) calls from LTE to the CS domain; 3) CS Fallback from LTE, for one or both ends of call, with maintenance of existing PS domain MPS services, either in LTE or in a legacy system, e.g., t
49、he GPRS Core; and 4) LTE access to MPS data and video services not under IMS control. 5 High level requirements 5.1 General Upon invocation of MPS, the system shall provide preferential treatment for access and core network resources associated with the session (i.e., signalling and media bearer related resources within a domain and across domains). A Service User is assigned a priority level by a regional/national authority i.e., agency authorised to issue priority levels. Upon MPS invocation the calling Service Users priority level is used to i
