Abstract:
An apparatus and a method for changing a MultiCast and BroadCast Service (MCBCS) broadcasting channel in a Broadband Wireless Access (BWA) system are provided. The method includes, if an MCBCS initialization request message is received from an MCBCS server, sending a burst reservation request message for MCBCS burst allocation to one or more Base Stations (BSs) in a corresponding Multicast and Broadcast Service (MBS) zone, and if a burst reservation response message is received from at least one of the one or more BSs, sending a Resource Reservation (RR) request message for each channel to the at least one of the one or more BSs for establishing data channels for each channel broadcast by the MCBCS server. Accordingly, a channel transition delay time resulting from a user's channel change can be reduced.
