Patent ID: 8325641

Claim:
A method for service identifying and routing in a multimedia broadcast and multicast service (MBMS) system, the method comprising: a radio access network (RAN) device obtaining identity information corresponding to a service that a user equipment (UE) joins, through interaction of interface information with a core network (CN); the RAN device identifying the service according to the identity information, and determining a route of the MBMS service in the non access stratum when using a Point to Point (PTP) bearer mode; wherein if there is an Iu connection of a Packet Switching (PS) domain on the UE, the RAN device obtains the identity information corresponding to the service the UE joins through a UE Linking procedure; and if there is an Iu connection of a Circuit Switching (CS) domain on the UE, the RAN device obtains the identity information corresponding to the service the UE joins through a MBMS service information requesting procedure.
