Apparatus and method for providing MBMS service in a mobile communication system

摘要

An apparatus and method for providing a multimedia broadcast/multicast service (MBMS) service between an RNC (140) and a Node B (150) in a mobile communication system including multiple UEs, the Node B having multiple cells, and the RNC for controlling the Node B. The RNC (140) transmits a request message including first information that can be determined according to services and second information that can be determined according to cells, to the Node B (150) in order to support the MBMS service. The Node B (150) generates a service context for providing an MBMS service according to the first information and the second information of the request message, and allocates identification information of the service context. The Node B sets up a transport bearer to the RNC according to the first information in the service context, and then, if the MBMS service data is received from the RNC (140) over the transport bearer, transmits the received MBMS data to the respective cells so that the UEs receive the MBMS data. <IMAGE>
