摘要： A point-to-point emulation apparatus and method in a broadband wireless communication system are provided. In a communication method in an RAS in a broadband wireless communication system, an ID of a source terminal and an ID of a destination terminal are registered in a database by mapping the ID of the source terminal to the ID of the destination terminal, for communications between terminals registered to the RAS. Upon receipt of traffic data from the source terminal, a header of the traffic data is converted using the database, for transmission to the destination terminal on a downlink.

摘要： An uplink packet data transmission system and method are provided which can reduce a collision probability in a contention period by assigning a priority to mobile stations when bandwidth allocation is rejected due to lack of resources of a base station from which a best effort service is provided. In a method for transmitting best effort data in a communication system, the base station allocates resources to mobile stations for which a reservation has been made in a previous time period when bandwidth for the mobile stations requesting bandwidth allocation is insufficient, reserves bandwidth for mobile stations for which the bandwidth allocation has been rejected, and transmits reservation information. The mobile stations receive the reservation information, skip a next scheduled bandwidth allocation request, and transmit data through bandwidth allocated from the base station.

摘要： A voice packet communication apparatus and method in a wireless communication system are provided. The communication method includes extracting, at a base station, RTP data from an IP packet received from a corresponding terminal in voice packet communication, generating the RTP data as a MAC PDU, and sending the generated MAC PDU to a wireless terminal; and extracting, at the wireless terminal, the RTP data from the MAC PDU received from the base station and reproducing the RTP data through a voice codec. Since the amount of data to be transmitted and received in the radio section is reduced, the present invention can enhance the bandwidth efficiency.
