Should the TSG modify the contents of 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: Ver

34、hird digit is incremented when editorial only changes have been incorporated in the document. Introduction This Technical Report (TR) provides a “Guide“ for Priority Service. The intent of this “Guide“ is to describe how existing 3GPP specifications support the high-level requirements identified for
35、 Priority Service in TR 22.950. Priority Service allows qualified and authorized users to obtain priority access to available radio (voice or data traffic) resources on a priority basis before other PLMN users during situations when PLMN congestion is blocking call attempts. In addition, Priority Se
36、rvice supports priority call progression and call completion to support an “end-to-end“ priority call. Priority Service is intended to be used by qualified and authorized users, i.e., key emergency service personnel and those with leadership responsibilities, only during times of emergency situation
37、s and network congestion. Priority Service providers should adhere to uniform, nationwide operating access procedures. Priority Service is to be available at all times in equipped markets in both the HPLMN and VPLMN within a country where a PLMN provider is offering the service. Priority Service is
38、applicable to both GERAN and UTRAN and is activated on a per call basis using Priority Service dialling procedures. Priority Service, supported by the 3GPP system set of services and features, is one element in the ability to deliver calls of a high priority nature from mobile to mobile networks, mo
39、bile to fixed networks, and fixed to mobile networks. ETSI ETSI TR 122 952 V14.0.0 (2017-03)73GPP TR 22.952 version 14.0.0 Release 141 Scope This present document addresses the Service Aspects (Service Description), Network Aspects (Call Flows), and Management Aspects (Operations, Administration, Ma
40、intenance, and Provisioning) of Priority Service, based on existing 3GPP specifications. The Priority Service is intended to be used for both Voice and Data. However, this document only addresses Circuit Switched Voice Service. Data, multimedia and non-circuit switched aspects of Priority Service ha
41、ve not been addressed and are for further study. The Priority Service is intended to interwork with external networks to provide an end-to-end service. Therefore, service interactions with external networks are considered within the scope of this document, although the specification of these interac
42、tions may be in another standard. If this occurs, a reference to that specification is made. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication
43、, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the

If no trunk is seized from the first trunk group (i.e., the queuing timer times out or the trunk group is not marked for
49、queuing), then the MSC proceeds to search the next trunk group in the routing chain. During the second search of the routing chain, the MSC can skip all busy trunk groups that are not marked for trunk queuing and directly proceed to search the first trunk group in the chain marked for queuing. Only Priority Service calls enter into Priority Service trunk queues. During the time that one or more Priority Service calls are held in a trunk queue for a particular trunk group, the MSC advances all non-Priority Service
