1. A method for using a navigation satellite positioning system to operate a femto cell base station in a wireless network, comprising:
- providing a navigation satellite positioning receiver in a femto cell base station to receive positioning signals from a navigation satellite positioning system;
providing a navigation satellite positioning client module in the receiver to communicate navigation satellite positioning messages with the network and to control the receiver in receiving the positioning signals;
providing a navigation satellite positioning server module in the network to communicate with the navigation satellite positioning client module and to maintain a database of location information of femto cell base stations in the network and corresponding geographic latitude, longitude and elevation data associated with a location of each femto cell base stations;
operating the navigation satellite positioning client module to send location address information of the femto cell base station to the navigation satellite positioning server module, wherein the location address information comprises at least a portion of an address associated with an area in which the femto cell base station is located;
in response to the location address information of the femto cell base station, operating the navigation satellite positioning server module to search in the database to get geographic latitude, longitude and elevation data associated with the location address information, compute the satellites covering the location based on the geographic latitude, longitude and elevation data and send the geographic latitude, longitude and elevation data and ID information of the satellites covering the location of the femto cell base station to the navigation satellite positioning client module;
operating the navigation satellite positioning client module to reset the receiver based on the geographic latitude, longitude and elevation data and ID information of the satellites from the navigation satellite positioning server module;
operating the receiver to acquire positioning signals from the satellites that are listed in ID information of the satellites from the navigation satellite positioning server module; and
operating the receiver to update the geographic data and timing data of the femto cell base station based on the acquired positioning signals.
