Abstract: PROBLEM TO BE SOLVED: To provide a wireless unit hand-off execution system that decides whether or not hand-off is required for a wireless unit and/or decides a base station that hands off the wireless unit by using the position information of the wireless unit. SOLUTION: For example, the wireless unit has a position system such as a global positioning system GPS to decide its own position. The wireless unit acquires the position information of itself and provides the position information to a base station in service. The base station in service detects that the wireless unit is moving away from a service area of the base station on the basis of the position information and decides the necessity of hand-off. Then the base station in service transmits at least part of the position information to an MSC, and the MSC can decide the base station that hands off the wireless unit. In other method, the base station in service can decide a base station that hands off the wireless unit.

Abstract: A system for performing a handoff of a wireless unit uses location information for the wireless unit to determine whether to handoff the wireless unit and/or to which base station to handoff the wireless unit. For example, a wireless unit can have a location system, such as a global positioning system (GPS), which determines the location of the wireless unit. The wireless unit can obtain location information for the wireless unit and provide the location information to the serving base station. From the location information, the serving base station can determine that the wireless unit is leaving the coverage area of the serving base station and may need to be handed off. The serving base station then can send at least a portion of the location information to the MSC, and the MSC can determine to which base station the wireless unit is handed off to based on the location information. Alternatively, the serving base station can determine to which base station the wireless unit is to be handed off.
