Introduction The response to emergency situations (e.g., floods, hurricanes, earthquakes, terrorist attacks) depends on the communication capabilities of public networks. In most cases, emergency responders use private radio systems to aid
25、 in the logistics of providing critically needed restoration services. However, certain government and emergency management officials and other authorised users have to rely on public network services when the communication capability of the serving network may be impaired, for example due to conges
26、tion or partial network infrastructure outages, perhaps due to a direct or indirect result of the emergency situation. Multimedia Priority Service, 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
27、nature from mobile to mobile networks, mobile to fixed networks, and fixed to mobile networks. ETSI ETSI TS 122 153 V15.0.0 (2018-07)53GPP TS 22.153 version 15.0.0 Release 151 Scope The present document specifies the service requirements for Multimedia Priority Service (MPS). The scope of this docum
28、ent is to specify those requirements of MPS necessary to provide an end-to-end service and to interwork with external networks where needed. Service interactions with external networks are considered within the scope of this document although these interactions may be specified in other standards. 2

A term defined in the present
33、document takes precedence over the definition of the same term, if any, in TR 21.905 1. MPS session: A session for which priority treatment is applied for allocating and maintaining radio and network resources. MPS-subscribed UE: A UE having MPS subscription. Priority Treatment: Refers to mechanisms
34、 and features that increase the success rate for MPS session invocation, establishment and maintenance until release. Service User: An individual 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 prio
35、rity assignments), and has a subscription to a mobile network operator that supports the MPS feature. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR 21.905 1 and the following apply. An abbreviation defined in the present document takes precedence over the
36、definition of the same abbreviation, if any, in TR 21.905 1. MPS Multimedia Priority Service ETSI ETSI TS 122 153 V15.0.0 (2018-07)63GPP TS 22.153 version 15.0.0 Release 154 General description MPS provides priority treatment to increase the probability of an authorized Service Users Voice, Video, a
37、nd Data communication session being successful. Some form of priority treatment is applied to the MPS invocation and session establishment, 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 i
38、n receiving, recognizing, and processing the invocation is needed. MPS allows qualified and authorized users to obtain priority access to the next available radio channel on a priority basis before other PLMN users, during situations when PLMN congestion is blocking session establishment attempts. I
39、n addition, MPS supports priority sessions on an “end-to-end“ priority basis. MPS is intended to be utilised for Voice, Video, and Data bearer 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 th
40、e CS domain when the network does not support the requested service in the PS domain. MPS Voice, Video and Data sessions are based on providing priority treatment to the corresponding commercial services offered to the public. MPS includes network functions that fall into the following broad categor
41、ies: Service Invocation: The process to recognize and identify a request for an MPS session. A MPS Service Provider network recognizes an MPS 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 U
42、E, or based on the subscription profile of the originating UE, or as a regional/operator option the subscription profile of the terminating 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 prior
43、ity only in the terminating network based on the terminating UE subscription profile. Authorization: The process to verify that a Service User is authorized for MPS. This includes capabilities to verify authorization to receive priority treatment in the radio access network and to access the MPS app
44、lication service (MPS Voice, Video, and Data). End-to-End Priority Treatment: The process of providing priority treatment in all parts of the 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 se
45、ssion path, the origination network and the termination network as well as any transit networks in between. Invocation-to-Release Priority Treatment: The process of providing priority treatment to all phases of a session, from invocation until release, including all steps in between. The combination
46、 of End-to-End Priority Treatment and Invocation-to-Release Priority Treatment includes both pre- and post-authorization treatment and includes the following aspects: 1) Priority processing of the Service Users MPS invocation, 2) Admission control and allocation of network resources (including beare
47、r resources) in origination, termination, and transit networks, including handovers, 3) Transport of signaling and media packets, 4) Priority processing within EPS and CN, and 5) Processing of the Service Users release of an MPS service session. Network Interconnection and Protocol Interworking: A S
48、ervice Users MPS invocation and session establishment will involve 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, inc
49、luding signaling for call/session establishment and media; 2) 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., the GPRS Core; and ETSI ETSI TS 122 153 V15.0.0 (2018-07)73GPP TS 22.153 version 15.0.0 Release 154) LTE access to MPS data and video services not under IMS control. 5 High level requirements 5.
