Abstract

La présente invention se rapporte à un procédé et à un appareil permettant de gérer des ressources multimédias dans un sous-système multimédia sur IP et qui résolvent le problème existant dans l'état de la technique selon lequel une mise à jour de ressources multimédias à sessions multiples dans des sessions ne peut pas être terminée à temps. Le procédé comprend les étapes suivantes : pendant le processus d'établissement de sessions avec une tonalité personnalisée, si une demande d'appel pour passer du domaine à commutation de paquets (PS) au domaine à commutation de circuits (CS) est détectée, les ressources multimédias de la session de négociation multimédia de tonalité personnalisée et de la session de négociation multimédia normale dans les sessions sont mises à jour en même temps. Avec la solution technique proposée par la présente invention, l'expérience de service de l'ancien support pour un abonné appelant n'est pas changée et la demande d'appel normale n'est pas affectée. Il n'est pas nécessaire de modifier l'architecture IMS existante et pour l'abonné appelant de faire une demande de commutation pour un déclenchement, ce qui permet de simplifier le flux de mise à jour des ressources multimédias. La solution technique résout le problème existant dans l'état de la technique selon lequel le flux de mise à jour de ressources multimédias est redondant, ce qui permet d'améliorer l'efficacité de mise à jour des ressources multimédias.
