Patent ID: 8588235

Claim:
A system for providing a multicast/broadcast service (MBS) using a Wireless Broadband Internet/World Interoperability for Microwave Access (WiBro/WiMAX) network, the system comprising: 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 with respect to the beginning and the end of the MBS bearer session which is received from the MBS control unit; an access control router (ACR) for performing an MBS channel authorization of an MBS user to determine which MBS channels the MBS user is authorized to use, in response to receiving a request for MBS bearer traffic, for allocating a multicast service flow identifier (SFID) with respect to the MBS bearer session in order to provide the MBS user with the MBS bearer traffic which is received from an MBS content source when the allocation of the QoS is requested, and for releasing the allocated multicast SFID when the release of the QoS is requested, wherein the multicast SFID comprises a unique value to classify the MBS bearer session in an identical MBS zone; and a radio access station (RAS) for allocating a multicast connection identifier (CID) corresponding to the allocated multicast SFID according to whether the MBS user requests the MBS bearer traffic, and controlling a radio resource with the MBS user, wherein, in response to the MBS user requesting a change in an MBS channel of the MBS bearer session, the ACR is configured to perform an authentication of the MBS user based on an MBS user profile of the MBS user which is received from a user authentication server.
