Abstract
A system and method for providing a multicast/broadcast service (MBS) using a Wireless Broadband Internet/World Interoperability for Microwave Access (WiBro/WiMAX) network are provided, which include an MBS control unit for generating a beginning and an end of an MBS bearer session, a quality of service (QoS) control unit for requesting an allocation and release of a QoS, an access control router (ACR) for allocating a multicast service flow identifier (SFID) with respect to the MBS bearer session in order to provide an MBS user terminal with MBS bearer traffic which is received from an MBS content source, and for releasing the allocated multicast SFID when the release of the QoS is requested, and a radio access station (RAS) for allocating a multicast connection identifier (CID) corresponding to the allocated multicast SFID according to whether an MBS user requests the MBS bearer traffic, and controlling a radio resource with the MBS user terminal.
