Abstract

Selon certains modes de réalisation, la présente demande concerne un procédé de notification d'une mise à jour d'élément dans une ressource collection. Le procédé consiste : à détecter s'il existe une mise à jour d'élément dans une ressource collection (301) ; si tel est le cas, à enregistrer un élément mis à jour dans une ressource de mise à jour d'élément (302) ; et à envoyer un message de notification de mise à jour d'élément à un dispositif d'abonnement abonné à une notification de mise à jour d'élément (303). Au moyen du procédé, un dispositif d'abonnement peut déterminer, par lancement d'un type d'abonnement à une ressource collection cible au moyen d'une seule interface, le contenu modifié et le contenu après le changement de la ressource collection, de façon à économiser des ressources système. De plus, le dispositif cible d'abonnement n'a également pas besoin de conserver davantage de relations d'abonnement, ce qui simplifie le flux de traitement.
