Abstract

Des modes de réalisation de la présente invention concernent un procédé et un appareil de notification d'anomalie de dispositif. Le procédé de notification comprend les étapes suivantes : un premier dispositif multimode détermine, lorsqu'une première interface CPL sur le premier dispositif multimode est déconnectée, un dispositif BM de veille d'un réseau CPL dans lequel la première interface CPL est située, la première interface CPL étant mise en œuvre en tant que BM dans le réseau CPL, le premier dispositif multimode étant un dispositif qui est capable de prendre en charge au moins deux interfaces de technologie de réseau domestique comprenant la première interface CPL, et chaque interface de technologie de réseau domestique correspondant à une interface sur le premier dispositif multimode ; et le premier dispositif multimode envoie un message de notification de dispositif déconnecté au dispositif BM de veille par l'intermédiaire d'un réseau dans lequel une autre interface sur le premier dispositif multimode à l'exception de la première interface CPL est située, de sorte que le dispositif BM sait que le BM est déconnecté ou qu'une anomalie est survenue dans le réseau CPL. Les solutions techniques de la présente invention permettent de réduire un retard dans la recherche d'une anomalie d'un BM dans un réseau hybride de type IEEE 1905.1.
