Abstract
A wireless access system and, more particularly, a method and apparatus for more efficiently performing zone switch are disclosed. The method of performing zone switch by an advanced mobile station (AMS) in a mixed-mode advanced base station (ABS) which operates in a mixed mode of a broadband wireless access system includes receiving a ranging response (RNG-RSP) message including system information of an AMS support zone from a legacy zone (LZone) of the ABS, and performing ranging to the AMS support zone using the system information.
