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

A method and system for handover of a video call from a packet switched network to a circuit switched network by a first network entity associated with the packet switched network in a single radio environment is provided. 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. Accordingly, a vSRVCC handover request is transtnitted to a second network entity associated with the circuit switched network for performing the vSRVCC handover of the video call session where the vSRVCC handover request includes vSRVCC capabilities of a user equipment (UE) associated with the video call session.
