摘要： An apparatus and method for selecting, releasing, and changing a MultiCast and BroadCast Service (MCBCS) of a Mobile Station (MS) in a Broadband Wireless Access (BWA) system are provided. The method includes, upon receiving a request to select a specific channel, transmitting a channel selection request message for selecting the channel; determining whether a DSA request message including a Media Access Control (MAC) layer name tag for the channel is received from an Access Service Network-Gateway (ASN-GW), and, upon receiving the DSA request message, transmitting a DSA response message to the ASN-GW; and receiving a channel selection response message including information indicating a success or failure of the channel selection from an MCBCS server. Accordingly, there is an advantage in that an overall transmission delay is reduced for an MCBCS call process, and a processing capacity can be effectively utilized.

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： 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.
