Abstract

L'invention concerne un procédé et un appareil de traitement de tranche de réseau. Le procédé comprend les étapes suivantes : un dispositif terminal accède à une tranche de réseau source ; le dispositif terminal envoie une demande de traitement de tranche de réseau à un gestionnaire de réseau ; le gestionnaire de réseau reçoit une demande de traitement de tranche de réseau envoyée par le dispositif terminal ; conformément à la demande de traitement de tranche de réseau, le gestionnaire de réseau accorde au dispositif terminal l'accès à une tranche de réseau cible correspondant à un identificateur cible, et acquiert des premières informations de configuration de protocole correspondant à la tranche de réseau cible ; et le gestionnaire de réseau envoie les premières informations de configuration de protocole au dispositif terminal. Les premières informations de configuration de protocole sont utilisées pour ordonner au dispositif terminal d'effectuer une configuration de protocole conformément aux premières informations de configuration de protocole, de manière à accéder à la tranche de réseau cible. Un dispositif terminal peut ainsi accéder correctement à une tranche de réseau cible, et le taux de réussite lorsque le dispositif terminal est commuté vers la tranche de réseau cible ou accède également à la tranche de réseau cible est amélioré.
