At a receiver location in a wireless communication system service area (22), a set of characteristics that describe a received ray of a subscriber signal is measured (26). In a model of the wireless communication system service area, a propagation path of a model ray launched from a location in the model of the wireless communication system service area that corresponds to the receiver location in the wireless communication system service area is determined (34), wherein the ray has model signal characteristics based upon the set of characteristics that describe the received ray of the subscriber signal. Thereafter, a subscriber location in the wireless communication system service area is estimated in response to the propagation path of the model ray.

A l'emplacement d'un récepteur dans une zone de service (22) de système de communication sans fil, un ensemble de caractéristiques décrivant un rayon reçu de signal d'abonné est mesuré (26). Dans un modèle de la zone de service de système de communication sans fil, un trajet de propagation d'un rayon modèle envoyé depuis un emplacement dans le modèle de la zone de service du système de communication sans fil, correspondant à l'emplacement du récepteur dans la zone de service du système de communications sans fil est déterminé (34), le rayon ayant des caractéristiques de signal modèle basées sur les caractéristiques décrivant le rayon reçu du signal d'abonné. L'endroit où se trouve l'abonné dans la zone de service du système de communication sans fil est estimé en réponse au trajet de propagation du rayon modèle.
