Method and apparatus for converging broadcast service and multicast service in a mobile communication system

摘要

A method and apparatus for simultaneously providing a multicast service and a broadcast service to a user to support MBMS in a CDMA mobile communication system are provided. A data generator, which can be in a BM-SC or an RNC, separately generates broadcast data and multicast data for a converged user service and simultaneously transmits the broadcast data and multicast data to users that have joined a broadcast session and a multicast session. When the multicast service is requested during receiving the broadcast service, a user terminal establishes a dedicated channel for receiving the multicast service, while maintaining a common channel for receiving the broadcast service, and then simultaneously receives the broadcast data and the multicast data on the common channel and the dedicated channel.
