Abstract

L'invention concerne un commutateur et un procédé de commande de tonalités de retour d'appel personnalisées permettant une application plus flexible de ces tonalités. Ce procédé consiste : à recevoir une demande d'appel du terminal appelant, cette demande contenant un numéro appelé ; à évaluer le mode de lecture de tonalité de retour d'appel personnalisée en fonction du numéro appelé ; et à établir respectivement les canaux entre le serveur de tonalités de retour d'appel personnalisées et les deux terminaux, appelant et appelé, en fonction du mode de lecture de tonalité de retour d'appel personnalisée, pour que le serveur de tonalités de retour d'appel personnalisées puisse envoyer la tonalité de retour d'appel personnalisée au terminal appelant et au terminal appelé. Le serveur de tonalités de retour d'appel personnalisées envoie la tonalité de retour d'appel personnalisée aux deux terminaux par lesdits canaux, de sorte que les deux terminaux n'aient pas besoin de télécharger la tonalité de retour d'appel personnalisée, ce qui permet d'économiser le temps de téléchargement et l'utilisation d'un canal de téléchargement. L'adoption du canal de lecture de tonalité de retour d'appel personnalisée n'est pas limitée par le type et la marque du téléphone mobile, ce qui élargit le champ d'application des tonalités de retour d'appel personnalisées et améliore la flexibilité de l'utilisation et de la personnalisation de ces sonneries.
