Abstract:
A method for determining a location of a mobile station within a wireless communication network, the wireless communication network including a plurality of base receivers coupled to a switch for receiving communication from the mobile station during a specified period of time, the method comprising:transmitting a signal from the mobile station for receipt by at least two of the base receivers; determining a timing error associated with the transmitted signal for each of the base receivers that received the transmitted signal; determining a separation distance between the mobile station and each base receiver that received the transmitted signal based at least upon the timing error; and determining the location of the mobile station within the wireless communication network based upon the separation distance between the mobile station and the base receivers that received the transmitted signal, wherein determining the location of the mobile station, further comprises: determining a circular region around a location of each base receiver that received the transmitted signal, each circular region having a radius equal to the separation distance between the mobile station and the respective base receiver; and determining an intersection point of the circular regions, thereby providing the location of the mobile station in the wireless communication network.
