Abstract
The present invention relates to a method of broadcasting and receiving a neighboring base station advertisement message in a wideband wireless access system and a handover method using the same. In the present invention, a base station broadcasts a neighboring base station advertisement message including information that indicates that frequency overlay is supported in neighboring base stations to terminals. The terminal confirms whether frequency overlay is supported in the neighboring base stations included in the neighboring base station advertisement message, and can perform handover to a frequency overlay supporting base station as a destination base station. According to the present invention, when a non-frequency overlay communication system and a frequency overlay communication system are mixed with each other, it is possible to ensure that a frequency overlay supporting terminal performs handover from a base station of a frequency overlay communication system to a base station of another frequency overlay communication system.
