Patent

CA 2153873

A method and system for authenticating the identification of mobile stations during system access is disclosed. A modified electronic serial number, including an encoded COUNT value, sent by the mobile station is compared with a modified electronic serial number corresponding to that mobile station stored in system memory. In this way, fraudulent use can be deterred and detected without changing the specification of information to be transmitted over the air interface in existing radiocommunication systems.

Procédé et système d'authentification de l'identification de stations mobiles pendant l'accès au système. Un numéro de série électronique modifié comprenant une valeur COUNT codée, émis par une station mobile, est comparé au numéro de série électronique modifié correspondant à cette même station mobile, stocké dans la mémoire du système. De cette façon il est possible de combattre et de détecter les utilisations frauduleuses sans modifier les spécifications de l'information à émettre via l'interface aérienne des systèmes de radiocommunications existants.
