The present invention relates to a broadband wireless access system, and more particularly, to a method for updating secondary carrier information in the event the multi-carrier configuration of a serving base station and the multi-carrier configuration of a target base station are different from each other during handover, for preemptively allocating secondary carriers. The present invention also relates to an apparatus for carrying out the method. A method in which a terminal performs handover in a broadband access system that supports multiple carriers according to one embodiment of the present invention comprises: a step in which a target base station receives, from a serving base station, a first message including carrier allocation information on at least one secondary carrier preemptively allocated to the terminal; a step of performing network reentry with the target base station; and judging whether the multi-carrier configuration of the serving base station and the multi-carrier configuration of the target base station are the same, and, if the configurations are different from each other, transmitting, to the target base station, a second message for requesting multi-carrier capability negotiation. |
