Abstract
In the area of mobile telecommunications, the performance of single radio voice call continuity (SRVCC) can be enhanced so as to provide video single radio voice call continuity (vSRVCC). Particularly, SRVCC/vSRVCC procedures can be configured for more efficient use of radio resources. A method includes receiving a query to determine in a multi-session scenario whether a last active session is a voice only session or a video session. A method also includes sending a response to the query indicating whether the last active session is the voice only session or the video session.
