A METHOD FOR HANDOVER BETWEEN FREQUENCY ALLOCATION IN BROADBAND WIRELESS ACCESS SYSTEM

摘要

A handover control method in a broadband wireless access system is disclosed. In a broadband wireless access system supporting multiple frequency allocations, in which a serving base station controls a handover, the present invention includes the steps of receiving from a mobile subscriber station a handover request message including an identifier of the mobile subscriber station, transmitting a handover request notification message including the identifier of the mobile subscriber station to a handover target base station, receiving a handover request notification response message including information for frequency allocation supportable by the target base station, and transmitting a handover response message including the information for the frequency allocation to the mobile subscriber station. Accordingly, in the broadband wireless access system supporting the multiple FA, the present invention enables the handover between FAs within one cell or between FAs in different cells.
