Abstract

La présente invention concerne un procédé et un dispositif d'obtention d'informations de capacité radio, un support de stockage et un dispositif électronique. Le procédé consiste à : recevoir des premières informations de capacité radio envoyées par un équipement utilisateur (UE), les premières informations de capacité radio étant utilisées pour indiquer la capacité de l'UE à accéder à un réseau radio ; chercher s'il existe des premières informations d'index dans une table d'informations de capacité radio stockée selon des informations d'index en tant que mot-clé primaire, les premières informations d'index étant générées selon les premières informations de capacité radio ; et si les premières informations d'index existent dans la table d'informations de capacité radio, obtenir des informations de capacité radio correspondant aux premières informations d'index à partir de la table d'informations de capacité radio.
