The contents of the present

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: Version x.y.z w
35、here: 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. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit i
36、s 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 Priority Se
37、rvice 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 Service suppor
38、ts 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 situations and networ
39、k 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 applicable t
40、o 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, mobile to fixe
41、d networks, and fixed to mobile networks. ETSI ETSI TR 122 952 V15.0.0 (2018-07)73GPP TR 22.952 version 15.0.0 Release 151 Scope This present document addresses the Service Aspects (Service Description), Network Aspects (Call Flows), and Management Aspects (Operations, Administration, Maintenance, a
42、nd 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 have not been
43、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 interactions may be
44、 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, edition nu
