摘要： A method for controlling an idle mode in a broadband wireless access (BWA) communication system. A mobile station (MS) transmits to a base station (BS) a de-registration request (DREG-REQ) indicating a state transition request to the idle mode. The BS transmits to the MS a de-registration command (DREG-CMD) for commanding state transition to the idle mode. The MS transmits to the BS a de-registration acknowledgement (DREG-ACK) in response to the DREG-CMD.

摘要： A method for determining a number of ranging slots by a base station (BS) in a broadband wireless access (BWA) communication system. The method includes counting the number of mobile stations (MSs) that succeeded in ranging in a current frame, determining a ranging slot occupation ratio in the current frame, comparing a ranging slot occupation ratio of a previous frame with the ranging slot occupation ratio of the current frame, detecting an increase in the number of ranging-requesting MSs, if the ranging slot occupation ratio of the current frame is greater than the ranging slot occupation ratio of the previous frame, and determining the number of ranging slots of a next frame such that the number of ranging slots of the next frame is greater than the number of ranging slots of the current frame.

摘要： A system and method for updating a sleep identifier (SLPID) of a mobile station (MS) in a broadband wireless access (BWA) communication system having a sleep mode in which there is no transmission data and an awake mode in which there is transmission data. Upon recognizing a need to update an SLPID allocated to an MS in the sleep mode in the initial phase of the sleep mode, a base station (BS) reallocates a new SLPID to be allocated to the MS and transmits SLPID update information to the MS. Upon receiving the SLPID update information for its current SLPID during the sleep mode, the MS updates its current SLPID with the reallocated SLPID according to the received update information.

摘要： Provided is a device and method for scheduling uplink resources in a wireless communication system supporting VoIP. When its data rate is decreased, an MS notifies a BS of the rate decreased. When increasing its data rate, the MS requests resource allocation to the BS by transmitting a BR header or a CQICH codeword. Compared to the conventional ertPS in which the BS periodically allocates uplink resources to the MS irrespective of the state of the MS, the BS does not allocate uplink resources when the MS transitions form a talk-spurt period to a silence period. Therefore, resources consumption arising from unnecessary bandwidth allocation is reduced.

摘要： In a communication system, a mobile station (MS) sends a target base station (BS) a notification indicating that it is to perform a handover from a serving BS to the target BS. The target BS transmits to the MS handover process optimization information indicating a possibility of omitting at least one process required by the MS to perform a network re-entry operation with the target BS according to the handover notification from the MS. The MS receives the handover process optimization information and performs a network re-entry operation with the target BS according to the handover process optimization information.
