Title
(EN) SYSTEM AND METHOD FOR THE EARLY DETECTION OF CELLULAR TELEPHONE PIRACY
(FR) SYSTEME ET PROCEDE DE DETECTION PRECOCE DE PIRATAGE DE TELEPHONES CELLULAIRES
Abstract
(EN) A method and system for early piracy detection in a cellular telecommunications network is disclosed. When in idle mode, a network subscriber Mobile Station (MS) transmits a Current Location Identifier message (CLID) on a pseudo-random basis. The CLID, which contains MS identifying information, is picked up by the network and relayed to the Mobile Switching Center (MSC) covering the area in which the MS is currently located. When it receives the CLID, the MSC generates an MS-CLID message containing the CLID and the identifier of the nodes through which it has passed, including that of the MSC itself. The MS-CLID message is then sent to the system Home Location Register (HLR), which compares the MS identification and location information to that stored in its database. The system generates a piracy alarm when the comparison determines that another caller using the same identity is currently active or that a call being initiated is originating from a location distant to the last reported location of the legitimate MS, allowing the system operator to take action prior to the loss of inordinate amounts of air time.
(FR) L'invention porte sur un procédé et un système de détection précoce de piratage dans un réseau de télécommunications cellulaires. En mode inactif, une station mobile d'abonné de réseau transmet un message d'identification de position courante sur une base pseudo-aléatoire. Ce message d'identification de position courante, contenant des informations identifiant la station mobile, est capté par le réseau et retransmis au centre de commutation mobile couvrant la zone dans laquelle se trouve généralement la station mobile. Lorsqu'il reçoit le message d'identification de position courante, le centre de commutation mobile génère un message contenant le message d'identification de position courante et l'identificateur des noeuds par lesquels il est passé, y compris celui du centre de commutation mobile lui-même. Le message est ensuite envoyé au registre de position de rattachement du système qui compare les informations d'identification et de positon de la station mobile à celles stockées dans la base de données. Le système génère une alarme de piratage lorsque la comparaison détermine qu'un autre appelant utilisant la même identité est généralement actif ou qu'un appel déclenché provient d'une position éloignée de la dernière position signalée de la véritable station mobile, ce qui permet à l'opérateur du système d'agir avant qu'il y ait une grande perte de temps d'appel.
