Abstract

L'invention concerne un procédé de commande d'accès à un découpage de réseau et un appareil de commande d'accès, une cellule terminale et un contrôleur SDN. Le procédé de commande d'accès qui est applicable à une cellule de terminal consiste : à acquérir des informations concernant au moins un découpage de réseau auquel un utilisateur a besoin d'accéder, de façon à obtenir des informations concernant au moins un découpage de réseau ; à envoyer des informations concernant ledit découpage de réseau à un contrôleur SDN ; et sur la base de la commande du contrôleur SDN, à accéder audit découpage de réseau. La solution technique de la présente invention permet à une cellule terminale d'accéder à l'avance à un découpage de réseau correspondant, de manière à fournir un service de réseau correspondant à un équipement d'utilisateur qui accède à la cellule de terminal, réalisant ainsi le support de la cellule de terminal au découpage de réseau.
