Selon le procédé, pour une signalisation de la liaison tc par l'intermédiaire du réseau de radiocommunication mobile, le numéro d'appel d'abonné de l'appareil terminal (10), qui pour une demande de liaison tc entrante, représente l'adresse cible originale et pour une demande de liaison tc sortante l'adresse originale de l'émetteur, est remplacé par le numéro d'appel d'une carte SIM (60) de la passerelle de radiocommunication mobile (30) de sorte qu'une signalisation entre le réseau de radiocommunication mobile (50) et la passerelle de radiocommunication mobile (30) soit effectuée en employant le numéro d'appel de la carte SIM (60) en tant qu'adresse cible de radiocommunication mobile ou en tant qu'adresse d'émetteur de radiocommunication mobile. Toutefois, l'adresse cible originale ou l'adresse d'émetteur pour la signalisation de la liaison tc est employée jusqu'à l'appareil terminal appelé (10, 80), le système de gestion (40) fournissant et/ou communiquant des informations d'attribution en vue de l'attribution de l'adresse cible originale à l'adresse cible de radiocommunication mobile ou en vue de l'attribution de l'adresse originale d'émetteur à l'adresse d'émetteur de radiocommunication mobile. La présente invention concerne en outre un dispositif de télécommunication et un système de gestion servant à exécuter le procédé.
