Disclosed herein is a method for determining the location of a mobile station with greater accuracy than serving base station location and yet preferably without the consumption of network resources typical of satellite-based location determination. The method is applicable in a scenario where a mobile station is ping-ponging (or has just been ping-ponging) between two non-coterminous wireless coverage areas. According the method, in that scenario, the location of the mobile station will be approximated conveniently as the location of overlap between the two wireless coverage areas, since it is most likely that the mobile station resides in that overlap area.
