Claim of US Patent No. 9,462,418

1. A method of operating a wireless communication device, comprising:
receiving wireless signals transmitted from a plurality of base stations and determining signal strengths for at least some
of the wireless signals;

identifying at least three geographically diverse ones of the base stations having signal strengths that satisfy a location-determination
strength threshold, wherein a signal strength of the signal strengths satisfies the location-determination strength threshold
when the signal strength is greater than a threshold signal strength value and less than a signal strength value that would
otherwise place a corresponding base station identifier in an active set for the wireless communication device; and

transmitting base station identifiers and associated signal strengths for the geographically diverse base stations.
