Abstract

La présente invention concerne un procédé et un dispositif de gestion des performances d'une instance de tranche de réseau. Le procédé comprend les étapes suivantes : un système de gestion de réseau envoie à un système de gestion d'élément une demande de création d'une tâche de gestion de performance, la demande comprenant des informations de fonctions de réseau qui comprennent un type de fonction de réseau et/ou une liste de fonctions de réseau. La demande comprend également au moins l'un des paramètres suivants : une liste d'instances de tranche de réseau, des informations de service, des paramètres d'instance de tranche de réseau et une liste d'instances de tranche de sous-réseau. Le système de gestion de réseau reçoit et traite des données de gestion de performance rapportées par le système de gestion d'élément, gérant ainsi les performances d'une instance de tranche de réseau et/ou d'une instance de tranche de sous-réseau.
