Abstract

L'invention concerne un procédé de commande de tranchage de réseau et un dispositif associé. Le procédé comprend les étapes suivantes : un dispositif terminal accède à une tranche de réseau source; la tranche de réseau source transmet des informations d'état de réseau à un dispositif de gestion de réseau central; le dispositif de gestion de réseau central reçoit les informations d'état de réseau transmises par la tranche de réseau source; si l'état de réseau satisfait une première condition prédéfinie, le dispositif de gestion de réseau central commande au dispositif terminal de commuter de la tranche de réseau source à une tranche de réseau cible. Au moyen de la présente invention, la pression de charge d'une tranche de réseau source peut être réduite, et des ressources de réseau de la tranche de réseau source peuvent être optimisées.
