ETSI TS 123 216 specifies the architecture enhancements for Single Radio Voice Call Continuity (SRVCC) between the following access systems 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 3GPP 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 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 continuity from E-UTRAN/UTRAN
(HSPA) to 3GPP UTRAN/GERAN CS accesses for voice calls is covered in this specification. SRVCC with priority
handling from E-UTRAN to 3GPP UTRAN/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) is 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 EUTRAN
to UTRAN-CS access for Video Calls that are anchored in the IMS.
