TS 23.206 (SA2)
Voice Call Continuity (VCC) between CS and IMS – Stage 2

ToC   3GPP‑Page   ETSI‑search   Help    
V7.5.0 (PDF)  2007/12  38 p.

Rapporteur:  Mr. Bennett, Andy
See also:  VCC-related TS/TR

This TS specifies the functional architecture and information flows of the Voice Call Continuity feature which provides the capability to transfer the path of an existing voice call between a 3GPP CS system (GSM/UMTS) and IMS, and vice versa. These capabilities were designed per requirements in TS 22.101.

Note:  No upgrade to Rel-8 due to change of approach to VCC. This TS is migrated to TS 23.237
