Method for updating secondary carrier information in a broadband wireless access system

The present invention relates to a broadband wireless access system, if more detail is previously the multicarrier set of handover when the serving base station and the target base station to assign secondary carriers of different methods for updating the secondary carrier information and the equipment to do this It relates. Way that the mobile station performs handover in a broadband wireless access system supporting multiple carriers according to an embodiment of the present invention, the carrier assignment information for at least one of the secondary carrier a target base station is pre-assigned to the MS from the serving base station receiving a first message including; Performing a network re-entry to the target BS; And can include the serving base station and if the multi-carrier set in the target base station determines whether or not (MC configuration) are the same, and different transmit a second message requesting the multi-carrier capability negotiation with the target base station.
