METHOD OF CHANGING A ZONE IN A BROADBAND WIRELESS ACCESS SYSTEM
First Claim
1. A method of performing a zone switch, which is performed by an advanced mobile station (AMS) in an advanced base station (mixmode ABS) operating in a mix mode in a broadband wireless access system, comprising the steps of:
- receiving a ranging response message (RNG-RSP) containing a system information on an advanced mobile station supporting zone (MZone) from a legacy zone (LZone) of the advanced base station; and
performing a ranging to the advanced mobile station supporting zone using the system information.

Abstract
The present invention relates to a broadband wireless access system, and more particularly, to a method of performing a zone change more promptly in a base station where an advanced terminal operates in a mix mode. A method for an advanced terminal (AMS) to perform a zone change in an advanced base station (mix mode ABS), which operates in a mix mode of a broadband wireless access system according to an embodiment of the present invention includes: receiving a ranging response message (RNG-RSP) including system information on an advanced terminal supporting zone (MZone) from a legacy zone (LZone) of the advanced base station; and performing ranging in the advanced terminal supporting zone by using the system information.
