摘要： A divided Media Access Control (MAC) protocol structure, a data transmission and reception method, and a handover method and system using the structure in a wireless communication system for efficiently managing session information in handover of an MSS (Mobile Subscriber Station). In the MAC protocol structure, a MAC is divided into a MAC-high layer and a MAC-low layer. The MAC-high layer performs session information-related functions and the MAC-low layer performs functions sensitive to a time delay in relation to handover of an MSS. In the handover method, when an MSS in the wireless communication system performs handover between Access Points (APs), session information is managed at a fixed position by an Access Point Controller (APC) including an MAC-high layer or a serving AP. Therefore, the system load can be reduced and communication quality can be improved.

摘要： A transmission apparatus and method for compressing headers in a broadband wireless communication system are provided. Upon receiving a packet to which a real-time transport protocol (RTP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header are added, from an upper layer, a header compression protocol layer transmits the received packet without compressing the headers at initial transmission, and from the next transmission, compresses the headers according to a compression scheme provided in Internet technology. A header compression convergence sublayer classifies the packet according to initial-header information received from the header compression protocol layer, stores mapping information for the packet classification, and performs packet classification on a header-compressed packet using the mapping information.

摘要： A method for allocating a safety channel to a handover subscriber station (SS) for data communication in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system. In the method, a base station (BS) determines a bin offset indicating a safety channel to be allocated to the handover SS and the number of subchannels every frame, generates a MAP information element (IE) with a set indicator indicating allocation of the safety channel, the MAP IE including SS identifier information indicating the handover SS, information on the determined bin offset and information on the determined number of subchannels, and transmits the generated MAP IE at a MAP IE transmission time in the frame. The handover SS receives the MAP IE from the BS every frame, and transmits/receives data for a predetermined number of frames in the allocated safety channel according to the MAP IE.
