Abstract
A wireless communication device transmits a position assistance request. A system database receives and processes the position assistance request to determine a time of the request and a location of the wireless communication device and processes the time and the location to determine if the system database stores positioning satellite information for the time and the location. The system database transfers the positioning satellite information to the wireless communication device if the positioning satellite information is for the time and the location. The system database transfers the position assistance request to a position determining entity if the system database does not store the positioning satellite information for the time and the location.
