Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.

La présente invention concerne un système et un procédé permettant de fournir une tonalité de retour de sonnerie dans un réseau de communication. On sollicite les fonctions de réseau intelligent, d'interruption momentanée de la production de signaux, de réacheminement d'appel ou de commutation, notamment, pour savoir si un utilisateur est inscrit au service de tonalité de retour de sonnerie. Si c'est le cas, on établit la liaison entre le commutateur appelant et le commutateur appelé, ainsi qu'une liaison entre le commutateur et le dispositif de tonalité de retour de sonnerie. Lorsque le terminal appelé est à l'état repos, le dispositif de tonalité de retour de sonnerie fournit à l'utilisateur appelant une tonalité de retour de sonnerie personnalisée par un utilisateur, laquelle tonalité de retour de sonnerie vient remplacer la tonalité conventionnelle de retour de sonnerie.
