Title: Method and apparatus for using advanced positioning systems in cellular communication networks

Abstract: A system and method that uses an advanced positioning system in combination with a cellular communication network to improve the performance of the network is disclosed One embodiment of the network includes a mobile switching center (MSC), a location tracker system (LTS), and a plurality of base stations for serving at least one mobile unit in the network. The LTS is able to receive a location code from the mobile unit that represents a specific coordinate, or location, in the network. The mobile unit may have generated the location code by analyzing its position from a global positioning satellite, or by other means. The LTS stores the location code in a data base. Whenever the MSC needs to communicate with the mobile unit, it queries the database of the LTS to determine the last location of the mobile unit. The MSC then selects one of the base stations that serves the location of the mobile unit and establishes a cellular link therethrough.
