GPS assistance messages in cellular communications networks and methods therefor
First Claim
1. A method for updating a satellite positioning system ephemeris data issue identifier transmitted to a satellite positioning system enabled mobile station in a cellular communications network, comprising:
- receiving satellite positioning system ephemeris data at a reference node in communication with a cellular communications network;
generating an assistance message including satellite positioning system ephemeris data and other parameters;
generating a satellite positioning system ephemeris data issue identifier;
receiving updated satellite positioning system ephemeris data and other updated parameters;
updating the satellite positioning system ephemeris data issue identifier only when the satellite positioning system ephemeris data has been updated.

Abstract
GPS assistance message and data issue identifiers for transmission to GPS enabled mobile stations in cellular communications networks and methods therefore. The GPS data issue identifiers indicate whether GPS data, for example corresponding ephemeris and almanac data, stored at the mobile station requires updating. In the exemplary 3rd generation (W-CDMA/UMTS) architecture, the GPS assistance message is a System Information Block (SIB), and the GPS ephemeris data identifier and corresponding satellite identifier is encoded in a value tag included in a Master Information Block (MIB).
