Abstract

L'invention concerne un procédé et un dispositif de notification pour le changement d'une ressource abonnée. Le procédé consiste à : détecter si une ressource abonnée et/ou une sous-ressource de la ressource abonnée sont/est changée(s) ; et lorsque la ressource abonnée et/ou la sous-ressource sont/est changée(s), selon une plage d'abonnement effective d'un abonné de la ressource abonnée, envoyer un message de notification à l'abonné, la plage d'abonnement effective comprenant la ressource abonnée et/ou la sous-ressource. Au moyen de la présente invention, le problème dans l'état de la technique associé selon lequel, si une pluralité de sous-ressources sont imbriquées au-dessous d'une ressource et si l'abonné a besoin d'acquérir des messages de notification des changements de toutes les ressources et de leurs sous-ressources, un CSE dans lequel les ressources abonnées sont situées consomme un grand nombre de ressources de stockage en raison du fait que des ressource abonnées ont besoin d'être créées pour des sous-ressources de chaque ressource, est résolu, permettant ainsi d'économiser des ressources de stockage.
