METHOD AND SYSTEM FOR HANDOVER OF VIDEO CALLS FROM A PACKET SWITCHED NETWORK TO A CIRCUIT SWITCHED NETWORK IN A SINGLE RADIO ENVIRONMENT

摘要

The present invention provides a method and system for handover of a video call from a packet switched network to a circuit switched network in a single radio environment. In one embodiment, a need to perform a video single radio voice call continuity (vSRVCC) handover from a packet switched network to a circuit switched network is detected during a video call session in the packet switched network by a network entity associated with the packet switched network. Accordingly, a vSRVCC handover request is sent to a network entity associated with the circuit switched network for performing a vSRVCC handover of the video call session where the handover request comprises vSRVCC capabilities of a user equipment (UE) associated with the video call session. Then, a vSRVCC handover procedure for handover of the video call session from the packet switched network to the circuit switched network is performed based on the vSRVCC capabilities of the UE.
