Patent

CA 2409231

A communications system and method is provided to reliably protect communication systems, such as mobile phone systems, from unauthorized use, as well as to make the interception of wireless communication more difficult. Specifically, the static wireless phone number or other similar identifiers are not used for identification and authorization during communication between the mobile unit and a base station. Instead, a set of private identifiers is determined and is known only to the phone company and the base stations controlling the mobile phone calls. These private identifiers allow dynamic and continual updating of the mobile phone and base station directories with current valid identifiers that are used for communication between the devices.

Système et procédé servant à protéger des systèmes de communication, tels que des systèmes de téléphone mobile, contre une utilisation illicite, ainsi qu'à rendre l'interception de communication radio plus difficile. Plus particulièrement, le numéro de téléphone sans fil statique ou d'autres identificateurs semblables ne sont pas utilisés pour effectuer une identification et une autorisation pendant la communication entre l'unité mobile et une station de base. On détermine à la place un ensemble d'identificateurs privés qui ne sont connus que de la compagnie de téléphone et des stations de base contrôlant les appels téléphoniques mobiles. Ces identificateurs privés permettent d'effectuer une mise à jour dynamique et continue des répertoires des téléphones mobiles et des stations de base au moyen d'identificateurs valides courants utilisés pour communiquer entre les dispositifs.
