Patent

CA 2266582

The present invention relates to a method and system for mobile location estimation in which range measurements between the mobile station and a base station are discriminated as being either from a base station which is line of sight with the mobile station or a base station that is non-line of sight with the mobile station (22). Non-line of sight error present in range measurements from base stations that are non-line of sight with the mobile station is corrected (24). A reconstructed line of sight range measurement is established from the correction of the non-line of sight error. The reconstructed line of sight range measurements can be used with range measurements of base stations determined to be line of sight for accurately locating the mobile station (26).

La présente invention concerne un procédé et un système d'estimation de position de station mobile dans lesquels on mesure la distance séparant la station mobile d'une station de base pour distinguer une station de base en visibilité directe (LOS) ou non (NLOS) de la station mobile (22). Les erreurs, dans les mesures de distance, indiquant une situation dans laquelle il n'y a pas de visibilité directe entre les stations de base et la station mobile sont corrigées (24). Les mesures de distance indiquant une situation dans laquelle il y a une visibilité directe sont reconstituées à partir de la correction de l'erreur indiquant qu'il n'y a pas de visibilité directe. Les mesures de distance reconstituées à partir de la correction peuvent être utilisées pour déterminer la visibilité directe afin de localiser avec précision la station mobile (26).
