Title
(EN) WIRELESS TELEPHONE LOCATION SYSTEM
(FR) SYSTEME DE LOCALISATION DE TELEPHONE SANS FIL
Abstract
(EN)
A tracking system for tracking a portable or mobile phone unit utilizes an array of fixed wireless signal transceivers forming part of a wireless telephone system. The phone unit includes a processor for generating an emergency signal on detection of an emergency condition and transmitting the emergency signal to a remote monitoring station via the wireless telephone network. The emergency signal includes identifying information for identifying the phone unit, as well as identifying control channel signals received by the phone unit from adjacent wireless signal transceivers which are retransmitted as part of the emergency signal to be used at the remote monitoring station to compute an approximate location of the phone unit.

Système de recherche d'un poste radio téléphonique portatif ou mobile, dans lequel on utilise un réseau d'émetteurs/récepteurs fixes de signaux sans fil, faisant partie d'un système de téléphone sans fil. Le poste téléphonique comprend un processeur destiné à produire un signal d'alerte lors de la détection d'un cas d'urgence et à transmettre ce signal à une station de surveillance située à distance au moyen du réseau de téléphone sans fil. Le signal d'alerte comporte des informations destinées à identifier le poste téléphonique ainsi que les signaux de la voie de commande reçus par le poste téléphonique à partir d'émetteurs récepteurs adjacents de signaux sans fil, lesdits signaux étant retransmis en tant que partie intégrante du signal d'alerte à traiter au niveau de la station de surveillance située à distance, afin de calculer l'emplacement approximatif du poste téléphonique.
