Abstract

Procédé et appareil d'analyse d'anomalie de performance de réseau, et support d'enregistrement lisible, qui sont utilisés pour analyser l'anomalie de paramètres de performance de réseau. Dans la présente demande, un premier appareil reçoit des informations d'exigence d'analyse d'anomalie de performance de réseau, analyse un paramètre de performance de réseau selon les informations d'exigence d'analyse d'anomalie de performance de réseau et envoie un résultat d'analyse d'anomalie de performance de réseau obtenu. Les informations d'exigence d'analyse d'anomalie de performance de réseau comprennent au moins l'une parmi des informations du paramètre de performance de réseau ou un type d'analyse d'anomalie de performance de réseau. Les informations du paramètre de performance de réseau comprennent au moins un identifiant parmi un identifiant du paramètre de performance de réseau ou des informations de catégorie du paramètre de performance de réseau. Le type d'analyse d'anomalie de performance de réseau comprend : une analyse de détection d'anomalie de performance de réseau, une analyse de cause d'anomalie de performance de réseau ou une analyse de suggestion de réparation d'anomalie de performance de réseau. De fait, le personnel d'exploitation et de maintenance n'a pas besoin de surveiller en temps réel une grande quantité d'informations, ce qui peut économiser de la main-d'œuvre, et une analyse d'anomalie de réseau peut être réalisée selon les besoins réels du personnel d'exploitation et de maintenance.
