Patent ID: 7925205

Claim:
In a wireless communication system having at least one repeater and a geolocation system for determining the location of a mobile appliance by measuring an attribute of the mobile appliance's uplink signal, a method of determining if the uplink signal is received directly from the mobile appliance or via the at least one repeater, comprising: estimating the location of the mobile appliance by the geolocation system; determining an accuracy of the estimate; determining if a Timing Advance (TA) of the uplink signal can be associated with the Equivalent Propagation Distance (EPD) of the at least one repeater, determining which receivers have received the uplink signal; determining which transmitted signals are received by the mobile appliance; determining the relationship between the power of the received signals and the power at which the mobile appliance transmitted the uplink signal; determining at least one figure of merit based on two or more of the accuracy of the estimate, the TA of the uplink signal, the equivalent propagation distance, the receivers receiving the uplink signal, the transmitted signals received by the mobile appliance, the power of the received signal, and the power at which the mobile appliance transmitted the uplink signal; and, comparing the at least one figure of merit to at least one or more threshold values to determine whether the uplink signal is received directly from the mobile appliance or from the at least one repeater.
