The invention relates to a method for establishing a connection from an initiating subscriber to a designated subscriber in a telecommunications network without providing the respective initiating subscriber with the permanent identifier of the designated subscriber. The invention provides that an anonymous identifier is assigned by a confidence instance (S, C) to the permanent identifier of the designated subscriber (B). In order to establish the connection via the initiating subscriber while using the anonymous identifier of the active home exchange (V), the utilized identifier is indicated as an anonymous identifier and is routed to the confidence instance (S, C). The confidence instance (S, C) determines the assigned permanent identifier from the routed anonymous identifier and transmits it to the home exchange (V). The home exchange (V) proceeds to establish the connection to the designated subscriber (B) while using the transmitted permanent identifier. An embodiment of the method also serves to transmit an anonymous identifier for a future return call to a called subscriber.
L'invention concerne un procédé d'établissement d'une connexion dans un réseau de télécommunications à partir d'un abonné de départ vers un abonné cible, sans que l'identification permanente de l'abonné cible ne soit connue de l'abonné de départ. Selon l'invention, une identification anonyme est assignée par une instance de confiance (S, C) à l'identification permanente de l'abonné cible (B). Pour permettre d'établir la connexion via l'abonné de départ en utilisant l'identification anonyme du central actif (V), l'identification utilisée est désignée comme identification anonyme et est transmise à l'instance de confiance (S, C). L'instance de confiance (S, C) détermine l'identification permanente assignée à partir de l'identification anonyme transmise et transmet ladite identification permanente au central (V). Le central (V) réalise l'établissement de la connexion à l'abonné cible (B) en se servant de l'identification permanente transmise. Un mode de réalisation du procédé sert également à transmettre à un abonné appelé une identification anonyme pour un rappel ultérieur.
