Abstract

La présente demande concerne un procédé et un appareil de gestion de défauts de réseau, utilisés pour améliorer le degré d'automatisation de la gestion de défauts de réseau. Dans la présente demande, une première unité de gestion de domaine reconnaît et classifie un premier défaut de réseau, comme la reconnaissance de la cause du premier défaut de réseau et/ou la détermination du sujet de réparation du premier défaut de réseau, et par conséquent, le premier défaut de réseau est traité en fonction d'informations de positionnement, de façon à améliorer l'automatisation dans la gestion de défauts de réseau, à réduire le degré d'intervention manuelle dans la gestion de défauts, à améliorer l'efficacité de gestion de défauts, et à empêcher également de multiples sujets de réparation de gérer de manière répétée un même défaut de réseau.
