Abstract

L'invention concerne un procédé de réalisation de service de rappel d'occupation, dans lequel une plate-forme de rappel reçoit un appel, qui est retransmis à la plate-forme lorsque le terminal appelé enregistrant le service de rappel d'occupation est occupé, cette plate-forme reconnaît les informations de terminal appelant et les informations de terminal appelé, passe un appel vers le terminal appelé, puis passe un appel au terminal appelant lorsque le terminal appelé est connecté. Un système de service de rappel d'occupation comprend un ensemble de modules dans un réseau commuté destiné à retransmettre un appel vers une plate-forme lorsque le terminal appelé enregistrant le service de rappel d'occupation est occupé, et une plate-forme destinée à recevoir le message appelant du terminal appelé du réseau commuté et à reconnaître les informations de terminal appelant et les informations de terminal appelé, la plate-forme passant un appel au terminal appelé, puis passant un appel au terminal appelant lorsque le terminal appelé est connecté. En rappelant au terminal appelé à travers le réseau qu'il y a un appel entrant par rappel automatique du terminal appelant, le service de rappel d'occupation enregistré par le terminal appelé peut être réalisé et le service peut se faire à travers diverses commutations.
