ABSTRACT:
A Global Positioning System (GPS) system includes multiple GPS application servers. The multiple GPS application servers provide GPS assistant information for locating a mobile terminal. The mobile terminal receives GPS information from multiple GPS satellites. The GPS assistant information is determined based on a GPS position and a geographic position of a GPS application server of the multiple GPS application servers. The GPS application server is nearest of the multiple GPS application servers to the mobile terminal, and the geographic position of the GPS application server is known.
