Title (EN) METHOD AND APPARATUS FOR DETERMINING THE POSITION OF A CELLULAR TELEPHONE
(FR) PROCEDE ET APPAREIL DE DETERMINATION DE LA POSITION D'UN TELEPHONE CELLULAIRE
Abstract: front page image
(EN)A method and apparatus to determine the position (116) of a remote station, such as a mobile cellular telephone using relative delay and absolute-range measurements. More particularly, the invention determines the position of a remote station (116) using a combination of forward link measurements made at the remote station (116) and reverse link measurements made at one or more base stations (106, 108). These measurements are used to perform calculations that yield the position of the remote station (116). An apparatus performing the calculations may use a-priori information on the exact location of all base stations participating in the mobile location determination, as well as inherent delay calibrations associated with the base stations.
(FR)L'invention concerne un procédé et un appareil de détermination de la position (116) d'une station à distance tel qu'un téléphone cellulaire mobile grâce à des mesures de retard relatif et de distance absolue. Plus particulièrement, l'invention permet de déterminer la position d'une station à distance (116) grâce à la combinaison des mesures de liaison aval effectuées dans la station à distance (116) et des mesures de liaison inverse effectuées dans une ou plusieurs stations de base (106, 108). Ces mesures s'utilisent pour calculer la position de la station à distance (116). Un appareil de calcul peut utiliser des informations a priori sur la position exacte de toutes les stations de base concernées par la détermination de la position du mobile, ainsi que des étalonnages de retard associés aux stations de base.
