ETSI ETSI TS 123 216 V15.2.0 (2018-07)73GPP TS 23.216 version 15.2.0 Release 151 Scope This document specifies the architecture enhancements for Single Radio Voice Call Continuity (SRVCC) between the following access syste
44、ms for voice calls that are anchored in the IMS: - from E-UTRAN to 3GPP2 1xCS; - from E-UTRAN to UTRAN/GERAN; - from UTRAN (HSPA) to UTRAN/GERAN. - from UTRAN/GERAN to E-UTRAN. - from GERAN to UTRAN (HSPA). This document will not describe 3GPP2 functional entities. However, interfaces between both 3
45、GPP and 3GPP2 functional entities are described in this specification. SRVCC from E-UTRAN access to 3GPP2 1xCS is covered in this specification, including the handling of IMS emergency call continuity. Handling of non-voice component and SRVCC from 3GPP2 1xCS to E-UTRAN direction is not specified in
46、 this release. SRVCC from E-UTRAN/UTRAN (HSPA) access and 3GPP UTRAN/GERAN CS accesses for voice calls that are anchored in the IMS, as well as the coordination between the SRVCC for voice call and the handover of non-voice PS bearers are covered in this specification. SRVCC with IMS emergency call
47、continuity from E-UTRAN/UTRAN (HSPA) to 3GPP UTRAN/GERAN CS accesses for voice calls is covered in this specification. SRVCC with eCall over IMS continuity from E-UTRAN/UTRAN (HSPA) to 3GPP UTRAN/GERAN CS accesses is covered in this specification. SRVCC with priority handling from E-UTRAN to 3GPP UT
48、RAN/GERAN CS accesses for voice or voice and video calls is also covered in this specification. The handover of non-voice PS bearer from E-UTRAN is specified by the procedures defined in TS 23.401 2, TS 23.060 10, TS 25.413 11 and TS 43.129 12. The handover of non voice PS bearer from UTRAN (HSPA) i
49、s specified by the procedures defined in TS 23.060 10, TS 25.413 11 and TS 43.129 12. This document specifies the architecture enhancements for Single Radio Video Call Continuity (vSRVCC) from E-UTRAN to UTRAN-CS access for Video Calls that are anchored in the IMS. 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 number, version number, etc.) or non-specific. - For a specific referenc
