Abstract

La présente invention concerne un procédé permettant à une passerelle média de signaler un état des ressources d'interface Iu. Le procédé comprend les étapes suivantes : la première étape consiste à ce que le serveur de centre de commutation de média envoie le message de commande transportant le paquet de signalement de congestion prolongée à la passerelle média (S202); le paquet de signalement de congestion prolongée transportant des informations de signalement d'état des ressources d'interface Iu; la seconde étape consiste à ce que la passerelle média signale l'état des ressources d'interface Iu au serveur de centre de commutation mobile sur la base des informations de signalement de l'état des ressources d'interface Iu (S204). Par l'invention, le paquet de signalement de congestion peut être étendu et le MSCS peut répartir logiquement la charge entre les MGW après la variation de la ressource du MGW au RNC.
