Abstract

La présente invention concerne un procédé et un appareil d'envoi d'informations, un procédé et un appareil de sélection de réseau, une station de base, un équipement utilisateur (UE), et un support de stockage lisible par ordinateur. Le procédé d'envoi d'informations consiste à : recevoir des informations de tranche de réseau configurées pour une station de base par un réseau central et supportées par la station de base ; et envoyer les informations de tranche de réseau prises supportées par la station de base à un UE en utilisant des informations système. Dans le mode de réalisation décrit, par la réception des informations de tranche de réseau configurées pour la station de base par le réseau central et supportées par la station de base, et par l'envoi des informations de tranche de réseau supportées par la station de base à l'UE en utilisant des informations de système, l'UE peut apprendre la tranche de réseau supportée par chaque station de base, et selon les informations d'une tranche de réseau supportée par une station de base et les informations d'une tranche de réseau supportée par l'UE, l'UE peut sélectionner un réseau à accéder, ce qui permet d'éviter le gaspillage de ressources système et de signalisation.
