METHOD, AND ASSOCIATED APPARATUS, FOR DETERMINING GEOGRAPHIC POSITIONING OF A WIRELESS COMMUNICATION STATION OPERABLE IN A NON-IDEAL PROPAGATION ENVIRONMENT

摘要

Apparatus, and an associated method, for determining the geographical positioning of a wireless communication station when the wireless communication station is operated in a non-ideal propagation environment. Errors introduced by NLOS (non line of sight) conditions in a determination of a position of the wireless communication station calculated by way of a trilateration technique are corrected. If too few signals are received at the wireless communication station to permit a determination of its position using a ray tracing pattern recognition technique, an estimate of the position of the wireless communication station is also determinable. When implemented in a cellular communication system, accurate position determinations are made even when the mobile station is operated in a non-ideal propagation environment, such as an urban area.
