Abstract
An apparatus and method for selecting, releasing, and changing a MultiCast and BroadCast Service (MCBCS) of a Mobile Station (MS) in a Broadband Wireless Access (BWA) system are provided. The method includes, upon receiving a request to select a specific channel, transmitting a channel selection request message for selecting the channel; determining whether a DSA request message including a Media Access Control (MAC) layer name tag for the channel is received from an Access Service Network-Gateway (ASN-GW), and, upon receiving the DSA request message, transmitting a DSA response message to the ASN-GW; and receiving a channel selection response message including information indicating a success or failure of the channel selection from an MCBCS server. Accordingly, there is an advantage in that an overall transmission delay is reduced for an MCBCS call process, and a processing capacity can be effectively utilized.
