Method for updating carrier information in a broadband wireless access system

摘要

The present invention relates to a broadband wireless access system, and more particularly, to a method in which a terminal acquires and updates global carrier configuration information of base stations in a network, and to an apparatus for performing the method. According to one embodiment of the present invention, a method in which a terminal acquires carrier configuration information in a broadband wireless access system that supports multiple carriers comprises the following steps; transmitting a first message containing a change count value of the carrier configuration information acquired by the terminal: receiving, from the base station and in response to the first message, a second message containing the current change count value of the carrier configuration information; and, if the change count value of the first message and the change count value of the second message are different from each other, receiving a third message containing current carrier configuration information and the current change count value from the base station.

主权项

1. A method of receiving carrier configuration information by a mobile station in a network supporting Multi-carrier, the method comprising:
transmitting, by the mobile station to a base station, a first message, the first message being a registration request (AAI-REG-REQ) message including a latest received value of a carrier configuration change count of the network, the value of the carrier configuration change count being a value which is changed according to a change of carrier information for all available carriers in the network; receiving, by the mobile station from the base station, a second message in response to the first message, the second message being a registration response (AAI-REG-RSP) message including a current value of the carrier configuration change count of the network; and when the latest received value of the carrier configuration change count is invalid based on a comparison between the latest received value of a carrier configuration change count and the current value of the carrier configuration count by the base station, receiving, by the mobile station from the base station, a third message, the third message being a global carrier configuration (AAI-Global-CFG) including current carrier configuration information, the current carrier configuration information including current carrier information for current all available carriers in the network.
