    Abstract: PROBLEM TO BE SOLVED: To provide a system that can dynamically decide a cell coverage in a wireless communication system. SOLUTION: The system to decide the coverage in the wireless communication system uses location information as to a wireless unit to collect information relating to communication between the wireless unit and the wireless communication system in cross-reference with the location information. The wireless communication system decides and/or receives the location information with respect to the wireless unit with other information related to the location information. The information for every location can be used to represent the coverage for a geographical area. For example, in the communication between a serving base station and the wireless unit, the serving base station receives and/or decides a signal quality measurement value of a forward link and/or reverse link in a specific location.

    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 determining coverage in a wireless communications systems uses location information for a wireless unit and collects information on communications between the wireless unit and the wireless communications system in association with the location information. The wireless communications system determines and/or receives location information for the wireless unit along with other information associated with the location information. The information by location can be used to represent the coverage of a geographic region. For example, during communications between a serving base station and a wireless unit, the serving base station could receive and/or determine signal quality measurements of a forward link and/or of a reverse link at a particular location. Additionally, neighboring base stations can monitor the communications and determine and/or receive location information for the location of the wireless unit along with the information associated with or corresponding to the location of the wireless unit. The associated information can be linked with additional parameters, such as wireless unit type, wireless unit identity, frequency, operating conditions and/or base station identity. In accordance with other aspects of the present invention, the information and/or measurements stored by location can be used to derive additional and/or different information by location or determine how the wireless communications system communicates with a wireless unit at a location, for example the base station to service the wireless unit at the location. A wireless unit in a location or range of location(s) could be served by a serving base station(s) at a certain transmit power and frequencies given certain operating conditions or parameters, such as time, weather, traffic load, path loss and/or interference level. A change in operating condition could trigger a dynamic change in the RF coverage provided by the serving base station(s) and/or neighboring base stations to the wireless unit(s) in the location or range of locations.

    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.

The associated information can be linked with additional parameters, such as wireless unit type, wireless unit identity, frequency, operating conditions and/or base station identity. In accordance with other aspects of the present invention, the information and/or measurements stored by location can be used to derive additional and/or different information by location or determine how the wireless communications system communicates with a wireless unit at a location, for example the base station to service the wireless unit at the location. A wireless unit in a location or range of location(s) could be served by a serving base station(s) at a certain transmit power and frequencies given certain operating conditions or parameters, such as time, weather, traffic load, path loss and/or interference level. A change in operating condition could trigger a dynamic change in the RF coverage provided by the serving base station(s) and/or neighboring base stations to the wireless unit(s) in the location or range of locations.
