Method for performing handover in broadband wireless access system

摘要

The present invention relates to a broadband wireless access system, and more specifically aims to define an efficient handover (HO) procedure when a base station having a relatively narrow coverage, such as femto base station, and a macro base station are both present. A method for performing a handover by a mobile station (MS) in a broadband wireless access system according to one embodiment of the present invention comprises the steps of: determining the type of a target base station that satisfies the pre-set handover trigger conditions; starting the handover procedure for the target base station when the target base station is a first type base station according to the determined results, and starting a first timer when the target base station is a second type base station having narrower coverage than the first type base station according to the determined results; and determining whether communication with the target base station is possible after the first timer has been completed, if the first timer had been started.

1. A method for performing handover in a broadband wireless access system, the method performed by a mobile station and comprising:
determining a type of a target base station which satisfies a preset handover triggering condition; performing a handover procedure for handing over to the target base station when the target base station is a first type of base station and starting a first timer when the target base station is a second type of base station whose coverage is smaller than a coverage of the first type of base station; and when the first timer is started, determining whether or not it is possible to communicate with the target base station after the first timer expires.
