The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG
33、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 where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates
34、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 is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 123 167 V15.2.0 (2018-
35、07)73GPP TS 23.167 version 15.2.0 Release 151 Scope This document defines the stage 2 service description for emergency services in the IP Multimedia Core Network Subsystem (IMS), including the elements necessary to support IP Multimedia (IM) emergency services and IM emergency services for eCall. I
36、TU-T Recommendation I.130 4 describes a three-stage method for characterisation of telecommunication services, and ITU-T Recommendation Q.65 3 defines stage 2 of the method. This document covers also the Access Network aspects that are crucial for the provisioning of IMS emergency services. Other 3G
37、PP specifications that are related to the IMS emergency services are TS 23.228 1 on IMS in general, including fixed broadband access aspects, TS 23.060 2 describing GPRS (UTRAN): TS 23.401 28 describing EPS (UTRAN and E-UTRAN); TS 23.402 29 describing Non 3GPP access (WLAN) to EPC; TS 23.271 5 that
38、covers location services; TS 23.216 31 and TS 23.237 32 describing Single Radio Voice Call Continuity (SRVCC) and Dual Radio Voice Call Continuity (DRVCC) for IMS Emergency session, TS 23.292 45 describing the use of IMS services when using CS access for the media bearer and TS 23.501 48 and TS 23.5
39、02 49 describing support of emergency services and location for 5GS. TS 25.301 6 contains an overall description of the UMTS Terrestrial Radio Access Network; TS 36.300 30 contains an overall description of the Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Rad
40、io Access Network (E-UTRAN); and TS 38.300 50 contains an overall description of the Next Generation Radio Access Network (NG-RAN). Other non-3GPP specifications that are related to the IMS emergency services include 3GPP2 cdma2000 HRPD IP-CAN, as specified in 3GPP2 X.S0060 25 when the UE is connect
41、ed to a PDS core network and 3GPP2 X.S0057-A 39 when the UE is connected to an EPC core network. The emergency support in different IP-CANs is described in the Informative Annex E. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of
