  • Patent number: 9408110
    Abstract: 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.

  • Patent number: 9160500
    Abstract: A method and apparatus for transmitting and receiving resource allocation information in a communication system are provided, in which a Base Station (BS) transmits resource allocation information including a folding bitmap and a Zone Flag (ZF). The folding bitmap provides zone configuration information about zones included in a subframe and the ZF indicates whether a last zone of the zones is allocated as a first service zone or a second service zone. The first service zone carries data for a first service, the second service zone carries data for a second service, and each of the first and second services zones includes at least one resource unit.

  • Patent number: 8879572
    Abstract: A method and an apparatus for recognizing a Multicast and Broadcast Service (MBS) region in a broadband wireless communication system are provided. In the method, whether a next MBS MAP message transmission point of a first frame and an MBS data burst transmission point indicated by MBS burst assignment information of a second frame match with each other in a third frame is determined. When matching with each other in the third frame, a control message including information for determining a starting point of an MBS region is generated. The generated control message is transmitted during one of the first and second frames.
