Abstract

L'invention porte sur un système et un procédé de communication et sur un point de commutation de service, sur un point de commande de service et sur un dispositif correspondant. Le système de communication de l'invention comprend un point de traitement de tonalité de retour d'appel et au moins deux plate-formes de tonalité de retour d'appel correspondant à différents numéros d'utilisateurs. Le point de traitement de tonalité de retour d'appel comprend une unité d'acheminement et une unité de notification. Lorsque le numéro utilisateur reçu du service appelant achemine un numéro d'accès de tonalité de retour d'appel, l'unité d'acheminement détermine la plate-forme de tonalité de retour d'appel correspondant au numéro utilisateur reçu du service appelant, conformément à ce dernier. L'unité de notification indique la plate-forme de tonalité de retour d'appel déterminée pour passer la tonalité de retour d'appel correspondant au numéro utilisateur. La présente invention permet à un réseau d'exploitation d'accéder à la fonction de plate-forme de retour d'appel fournie simultanément par différents fournisseurs, et ainsi des utilisateurs dans différents segments de numéros peuvent effectuer des services distincts.
