Abstract

La présente invention concerne un procédé destiné à la restriction d'un service de tonalité de rappel personnalisée (CRBT), utilisé pour restreindre la tonalité de rappel personnalisée lorsqu'un abonné demandeur appelle un abonné demandé dans un réseau de communication fixe. Ce réseau de communication fixe comprend au moins un central de départ, au moins un central d'arrivée et au moins une plate-forme de tonalité de rappel personnalisée. Le central de départ est conçu pour envoyer un paramètre au central d'arrivée, ce paramètre étant défini par la spécification de l'opération et indiquant que l'abonné demandeur connecté audit central de départ est demandeur du service de restriction de tonalité de rappel personnalisée. La présente invention permet de restreindre un service de tonalité de rappel personnalisée. Ainsi, lorsqu'une personne n'apprécie pas la tonalité de rappel personnalisée, elle entendra la sonnerie normale lorsqu'elle appellera l'abonné appelé. Ce procédé a peu d'effet sur les antériorités portant sur le service de tonalité de rappel personnalisée et aucun effet sur la structure du réseau de communication fixe et est, par conséquent, compatible avec le réseau existant.
