CA 2257992

A network-based telecommunications system and method that restricts the dial- in access to a resource of a subscriber to only a communication from an authorized user of the source. A switch receives a communication directed to a subscriber from a calling party. Prior to connecting the communication to the terminating equipment associated with the subscriber, the switch requests processing information. An authentication unit determines whether the calling party is an authorized user by checking whether a passcode provided by the calling party corresponds to a passcode being held by the authentication unit. If the passcode corresponds, then the authentication unit identifies the calling party as an authorized user, and the communication then may be connected to the terminating equipment of the subscriber. If the passcode fails to correspond, then the authentication unit fails to identify the calling party as an authorized user. The communication is not connected to the terminating equipment of the subscriber.

L'invention concerne un système et un procédé de télécommunications en réseau restreignant l'accès par réseau commuté à une ressource d'un abonné seulement aux communications par un utilisateur autorisé de la ressource. Un commutateur reçoit une communication envoyée à un abonné par un appelant. Avant la connexion de la communication à l'équipement terminal associé à l'abonné, le commutateur demande le traitement de l'information. Une unité d'authentification détermine si l'appelant est un utilisateur autorisé en vérifiant si un code d'accès produit par un appelant correspond à un code d'accès conservé par l'unité d'authentification. Si le code d'accès correspond, l'unité d'authentification identifie l'appelant comme un utilisateur autorisé, et la communication peut ensuite être connectée à l'équipement terminal de l'abonné. Si le code d'accès ne correspond pas, l'unité d'authentification n'identifie par l'appelant comme un utilisateur autorisé. La communication n'est pas connectée à l'équipement terminal de l'abonné.
