| Abstract: |
A system and method for providing different levels of mobile communication service for a mobile station within a communication system service area. A plurality of base transceiver stations (BTSs) are coupled to a common database. Each BTS has a cellular service area for communicating with the mobile station, a unique identification, and is located with respect to other base transceiver stations for defining a plurality of overlapping cellular service areas which collectively define the service area of the communication system. The common database has a memory for storing data related to a home geographical location associated with the mobile station, and the identity of the BTSs having service areas overlapping the home geographical location. The geometric shapes of the service areas overlapping the home geographical location of the mobile station define a home calling area. A first level of service is provided to the mobile station when the mobile station is inside the home calling area, and a second level of service when the mobile station is outside of the home calling area. The second level of service may be defined by the identities of additional BTSs for providing a third level of service beyond the service areas of these additional BTSs.

What is claimed is:
1. A method for providing different levels of mobile communication service for a mobile station within a communication system service area, the communication system including
- a common database having a memory, said common database having data related to grid coordinate data of a geographical location, and
- a plurality of base transceiver stations, each base transceiver station having a unique identification, being coupled to the common database providing a cellular service area for communicating with the mobile station, and being located with respect to other base transceiver stations for defining a plurality of overlapping cellular service areas, the plurality of cellular service areas defining the service area of the communication system,
- the method comprising the steps of:
- associating a home geographical location with the mobile station, the home geographical location being located inside the service area of the communication system;
- determining the identification of each base transceiver station having a cellular service area overlapping the home geographical location;
- defining a home calling area for the mobile station to be the cellular service areas determined to overlap the home geographical location;
- storing the identification of each base transceiver station having a cellular service area defining the home calling area in the memory of the common database;
- determining a physical location of the mobile station with respect to the home calling area;
- providing a first level of mobile communication service to the mobile station when the mobile station is determined to be inside the home calling area; and
- providing a second level of mobile communication service to the mobile station when the mobile station is determined to be outside of the home calling area.
