摘要：Apparatus, and an associated method, for determining the geographical

positioning of a wireless communication station when the wireless communication stationis operated in a non-ideal propagation environment. Errors introduced by NLOSconditions in a determination of a position of the wireless communication stationcalculated by way of a trilateration technique are corrected. If too few signals arereceived at the wireless communication station to permit a determination of its positionusing a ray tracing pattern recognition technique, an estimate of the position of thewireless communication station is also determinable. When implemented in a cellularcommunication system, accurate position determinations are made even when the mobilestation is operated in a non-ideal propagation environment, such as an urban area.
