Abstract

La présente invention concerne un procédé, un appareil et un système de traitement de porteuses, utilisés dans un scénario dans lequel un équipement utilisateur établit une pluralité de porteuses. Un dispositif de gestion de mobilité, prévu par les modes de réalisation de l'invention, reçoit un message de réponse de l'établissement d'une partie des porteuses envoyées par l'équipement utilisateur ; et le dispositif de gestion de mobilité envoie à un dispositif passerelle un message de réponse de réussite de l'établissement des parties des porteuses et un message de réponse d'échec de l'établissement d'autres parties des porteuses, avant un délai d'expiration prédéfini. L'invention peut atteindre les performances d'un service voulu par le biais d'une partie de porteuses déjà établie, ce qui permet d'assurer l'efficacité du service.
