Method and system for handover in a broadband wireless access communication system

The present invention relates to a handover method and system in a Broadband Wireless Access (BWA) communication system, this present invention provides a method for providing handover in a broadband wireless access communication system, the data transmission domain for each mobile terminal handover If the area and the process to separate the normal user field, a move a given mobile terminal does not perform hand-over device, allocating at least one subchannel in the normal user field, a predetermined mobile terminal is handed over movement If the terminal, and allocating at least one subchannel in the handover field includes the step of performing communication via the at least one sub-channel for the assigned. OFDMA, frequency reuse factor, the handover, hard handover, a subchannel
