摘要： Disclosed is a system and a method for controlling a handover of a mobile subscriber station in a broadband wireless access communication system. When serving base station determines to perform a handover of the mobile subscriber station, neighbor base stations to which the mobile subscriber station can be handed over, from among neighbor base stations of the mobile subscriber station, are determined based on a service quality level of service being currently provided to the mobile subscriber station. A handover request signal containing information related to the determined neighbor base station to which the mobile subscriber station can be handed over is transmitted to the mobile subscriber station. The serving base station receives from the mobile subscriber station in response to the request of the handover information about one neighbor base station to which the mobile subscriber station will be handed over, and informs the neighbor base station that the mobile subscriber station will be handed over to the neighbor base station.

摘要： A system and method for allocating a safety channel in a broadband wireless access (BWA) communication system including a serving base station (BS) for providing a service to a mobile station (MS) and neighbor BSs. Upon receiving a request for allocation of the safety channel from the MS, the serving BS sends a request for allocation of the safety channel to a target BS having the best channel condition among the neighbor BSs. Upon receiving information indicating possibility of allocating the safety channel from the target BS, the serving BS controls the MS such that the MS performs communication through the allocated safety channel. Upon detecting a need for receiving a safety channel, the MS sends, to the serving BS, information indicating that the MS should be allocated the safety channel, and receives a safety channel allocated according to a control signal from the serving BS.

摘要： Disclosed is a method for allocating a safety channel in a wireless communication system which divides a full frequency band into a plurality of subcarrier bands and includes subchannels, each of which is a set of a predetermined number of subbands, each of which is a set of a predetermined number of contiguous subcarriers, where the subchannels include a safety subchannel allocated to particular subscriber stations (SSs), which is unused in a neighbor base station. The method comprises the steps of: transmitting, by the SS, its channel quality information to the base station (BS) when a channel quality of a subchannel allocated to the SS is less than to predetermined reference channel quality; and allocating a safety subchannel to the SS, by the BS upon receiving the channel quality information indicating that the channel quality of the subchannel is less than to the reference channel quality.

摘要： In a BWA communication system, an MSS changes its connection from the serving BS to the target BS, and sends the target BS a report indicating that the MSS will change its connection upon detecting occurrence of a pingpong effect in a process of performing a network re-entry operation with the target BS. The target BS sends the serving BS a notification indicating that the MSS will change its connection. Upon receiving from the MSS a report indicating that it will change its connection to the serving BS, the serving BS allocates a contention-free-based ranging resource to the MSS so that the MSS connects a communication service with the serving BS using the contention-free-based ranging resource, minimizing a service delay.

摘要： A system and method for dynamically allocating a frame cell (FC) and subchannel (FC/subchannel) is disclosed. An access point receives channel quality information (CQIs) which is fed back from a plurality of access terminals on an FC-by-FC basis, and determines a modulation and coding scheme (MCS) to be applied to each of the access terminals. If access terminals whose FCs/subchannels must be changed are detected from the plurality of the access terminals, the access point sends an FC/subchannel change request for the detected access terminals to an access router. The access router generates weights for all FCs, allocates an FC/subchannel set by selecting a predetermined number of FCs/subchannels considering the weights of the FCs for the access terminals corresponding to the received FC/subchannel change request, and transmits information on the allocated FC/subchannel set to the access point. The access point selects and allocates a particular FC/subchannel from among FCs/subchannels in the FC/subchannel set information received from the access router for the access terminals whose FCs/subchannels must be changed, based on CQIs last received from the access terminals whose FCs/subchannels must be changed.
