摘要： An apparatus and method for providing a Multicast and Broadcast Service (MBS) in a Broadband Wireless Access (BWA) system are provided. The apparatus includes a fragmentation unit, a Generic Routing Encapsulation (GRE) packet generator, and a communication unit. The fragmentation unit fragmentizes MBS traffic received from a network for synchronization. The GRE packet generator generates a GRE packet with each of segments from the fragmentation unit. The communication unit transmits the GRE packet from the GRE packet generator to a Base Station (BS) in consideration of a packet period.

摘要： A method and apparatus for managing a buffer of a Radio Access Station (RAS) in a communication system are provided. An available buffer space determiner sets a threshold for each service class for scheduling packet input/output of the buffer according to priority of a service class, estimates and stores, upon receipt of a packet at the buffer, an available space size of the buffer after the packet reception, compares the estimated available space size of the buffer with a first threshold corresponding to a first service class indicative of a service class of the packet, and schedules packet input/output of the buffer according to the comparison result. A processor module schedules packet input/output of the buffer according to an output of the available buffer space determiner. The present invention can improve quality of services through service differentiation based on priorities of service classes and buffer management based on characteristics of the corresponding service traffics.

摘要： 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.

摘要： A network includes a Mobile Station (MS) for sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF. The BS sends a path modification request message to a serving SF Authorization (SFA) when there is the information on the SF. The BS also sends an SF modification response message comprising a Confirmation Code ‘Reject SF not found’ to the MS when there is no information on the SF. The serving SFA sends a resource reservation request message to an anchor SFA when there is the information on the SF, and sends a path modification response message comprising a Failure Indication (FI) ‘Requested Context Unavailable’ to the BS when there is no information on the SF. The anchor SFA sends a resource reservation response message comprising the FI ‘Requested Context Unavailable’ to the serving SFA when there is no information on the SF.
