Abstract
An apparatus and method for a Multicast and Broadcast Service (MBS) in a Broadband Wireless Access (BWA) system. In a method for operating a user terminal in a BWA system, an idle timer is driven when a flow for unicast connection has no traffic in an awake mode. Whether a broadcast service is being received is checked when the idle timer expires. The user terminal transitions from the awake mode to a fake idle mode when the broadcast service is being received.
