Embodiments of the present invention disclose a method and apparatus for service identifying and routing in a multimedia broadcast and multicast service (MBMS) system. The apparatus includes a radio access network equipment (RNC) and a core network equipment (CN) communicating with each other via an Iu connection; CN includes a module for service information transmission which is used to send the identity information corresponding to the service the UE joins to RNC, and RNC includes a module for service identifying and routing which is used to identify the service according to the identity information and determine the routing of the MBMS service in the non access stratum. RNC obtains the identity information corresponding to the service the UE joins through interaction of interface information with CN, identifies the service and determines the routing of the MBMS service in the non access stratum.
