摘要： Provided is an apparatus and method for efficiently transmitting packets to MSs in a BWA system using RSs. A BS uses an ESH to combines packets, which are to be transmitted through RSs to MSs, into a larger packet prior to transmission. Alternatively, the BS transmits packets, which are to be transmitted to MSs, to an RS without discrimination therebetween, and the RS determines whether the packets are to be transmitted to the MSs, prior to transmission.

摘要： A frame configuration method and apparatus for sending data via an RS in a broadband wireless communication system are provided. In the reception mode, the RS monitors reception of data in an (n−1)th frame from an MS and reception of data in an nth frame from a BS. The RS classifies the data received from the MS and the data received from the BS as combinable data to be sent in combination or as non-combinable data to be sent separately, and stores the classified data distinguishably. When the RS transitions to a transmission mode, it determines whether to XOR-operate or mask the stored data. If the stored data can be masked, the RS XOR-operates the stored data and sends the masked data to the BS and the MS.

摘要： An apparatus and method for reducing MAP channel overhead in a broadband wireless communication system. In a Base Station (BS), a traffic classifier classifies transmission data into a first group and a second group according to user channel information and packet sizes of the transmission data. A MAP channel configure configures a MAP channel to include information about users of the first group and positions of data for the users, information indicating whether users of the second group have succeeded in random access in a second uplink data region of a previous frame, and information about resource reservation for a current frame for the second group. A channel mapper maps the first group to a first downlink data region and maps the second group to a second downlink data region according to the MAP channel.

摘要： A method and an apparatus for controlling call admission in an OFDM mobile communication system are provided. Upon receipt of a call admission request, it is determined whether a requested call is a handoff call or a new call and the traffic service type and QoS level of the requested call are determined. The amount of resources required for the call is calculated using the QoS level and the amount of resources of on-going calls is calculated according to the traffic service type. The amount of available resources in a cell is calculated using the amount of resources of the on-going calls and it is determined whether to admit the call by comparing the available resource amount with the required resource amount.

摘要： A frame communication apparatus and method for a broadband wireless communication system are provided that employ a transmitter. In the transmitter, a control channel generating unit generates burst allocation information including a receiver identification (ID) with respect to a transmission packet, a burst generating unit constructs data burst by adding a header including a traffic ID to the transmission packet, and a transmitting unit transmits the burst allocation information and the data burst. An existing connection ID (CID) is subdivided into a user ID (UID) and a traffic ID (TID). The UID and the TID are recorded in a map channel message and a medium access control (MAC) header, respectively. Accordingly, an amount of information contained in a downlink map (DL-MAP) and uplink map (UL-MAP), and an amount of the MAC header of a data packet can be reduced.

摘要： Provided are an apparatus and a method for providing a concurrent data service to an Mobile Station (MS) through a plurality of heterogeneous networks. In a method for providing a data service to an MS through different wireless networks, the MS measures channel qualities of at least one accessible wireless network and reports the measured channel qualities to an Internet Protocol (IP) packet controller. The IP packet controller selects wireless networks for data transmission on the basis of the reported channel qualities, distributes data destined for the MS, and transmits the distributed data to the selected wireless networks. The selected wireless networks receive the data from the IP packet controller and transmits the received data to the MS. The MS combines and interprets the data received from the selected wireless networks. Accordingly, it is possible to provide a seamless data service to the MS in service environments with a mixture of different wireless communication systems.
