Patent ID: 8873368

Claim:
A method for processing a channel switching failure case, wherein the method is applied to provide media service to a user terminal through unicast and multicast, and comprises: receiving a failure case message or a failure case processing message from a terminal device; parsing the failure case message or the failure case processing message; processing the failure case according to the parsed failure case message or the parsed failure case processing message, wherein the processing the failure case according to the parsed failure case message or the parsed failure case processing message comprises: stopping sending current data stream to the terminal device, when the failure case message comprises information indicating that there are repeated data streams beyond a preset condition in received unicast and multicast streams; and sending the current data stream synchronized with the multicast stream to the terminal device, when the failure case message comprises information indicating that the received unicast stream is asynchronous with the currently received multicast stream after the sending of unicast streams is stopped, or no data synchronized with the currently received multicast stream needs to be sent to the terminal device.
