Abstract
An assisted wireless position determination system includes a plurality of base stations and a plurality of wireless devices, such as mobile telephones and personal digital assistants, adapted to communicate with the base stations. The wireless position determination system also includes a position determination system for determining the geographic position of the wireless devices. The position determination system includes a position determination entity (PDE) that is connected to the base stations and serves as a processing server for computing the position of the wireless devices. The system and method reduces or eliminates redundant and superfluous data. In addition, the system and method ensure that the wireless device is not loaded with additional capacity, and that the wireless device is provided with precise location information. The embodiments of the system and method of the invention are compliant with the TIA/EIA IS-801 standard or other standards.
