Abstract:
Methods, systems, and computer readable media for performing single radio voice call continuity (SRVCC) handover are disclosed. According to one method, the method occurs at a testing platform. The method includes receiving, via a communications channel for exchanging messages between a first session initiation protocol (SIP) peer and a second SIP peer, a first message for triggering a bearer deletion procedure associated with a call between the first SIP peer and the second SIP peer. The method also includes in response to receiving the first message or a related message, triggering the bearer deletion procedure prior to changing an access technology.
