Abstract
Disclosed is a method and apparatus for determining the location of a mobile station based on the locations of a group of nearby mobile stations. A mobile station implementing the method will engage in short-range wireless communication with nearby mobile stations to determine the location of the nearby mobile stations and the distances between it and each nearby mobile station. The mobile station will then apply triangulation or another algorithm to compute its own location based on the determined locations and distances of the nearby mobile stations. Further, a serving radio access network can assist by providing a trust-signal to the nearby mobile stations, with the nearby mobile stations then reporting their locations conditional upon their receipt of both the location query and the trust-signal.
