Patent ID: 8547978

Claim:
A method for providing a Multicast/Broadcast Service (MBS) to a mobile terminal in an MBS provisioning system of a Wide Area Network (WAN) network, the method comprising: transmitting, by an authentication server, a resource reservation request message including a Quality-of-Service (QoS) policy for a multicast control message, wherein the multicast control message is used by the mobile terminal to request reception of the MBS and/or release from the MBS, and the QoS policy allows the WAN network and the mobile terminal to share a QoS policy for stably sending the multicast control message; storing, by a base station, the resource reservation request message, and transmitting the resource reservation request message to the mobile terminal; transmitting to the base station, by the mobile terminal, a request for channel setup based on the QoS policy; setting up, by the mobile terminal, a channel between the mobile terminal and the base station according to a response to the request for channel setup based on the QoS policy; and transmitting to the base station, by the mobile terminal, the multicast control message for requesting reception of the MBS over the channel based on the QoS wherein the setting up comprises setting up the channel using at least one of a pre-provisioned connection-based method, a provisioning connection-based method, a dynamic connection-based method, and a Media Access Control (MAC) Layer management Connection Identifier (CID)-based method for transmitting to the base station a MAC management message that corresponds to the multicast control message, and the dynamic connection-based method is a method for setting up the dynamic connection between the mobile terminal and the base station when there is an intention to transmit the multicast control message, and releasing the dynamic connection when a reference time has elapsed and no multicast control message is transmitted during the reference time.
