Abstract

La présente invention concerne un procédé et un dispositif permettant de configurer un dispositif terminal. Le procédé comprend les étapes suivantes : avant une commutation de cellule, un dispositif terminal détermine des premières informations de configuration d'un premier dispositif réseau, le premier dispositif réseau étant un dispositif réseau source à partir duquel le dispositif terminal effectue une commutation de cellule ; pendant la commutation de cellule, le dispositif de terminal reçoit des deuxièmes informations de configuration en provenance d'un second dispositif réseau, le second dispositif réseau étant un dispositif réseau cible vers lequel le dispositif terminal effectue une commutation de cellule ; le dispositif terminal détermine que les premières informations de configuration comprennent un premier champ, et que les deuxièmes informations de configuration ne comprennent pas un premier champ, le premier champ étant un champ qui doit être hérité ; et le dispositif terminal libère une configuration, correspondant au premier champ, comprise dans les premières informations de configuration. Dans les modes de réalisation de la présente demande, un dispositif terminal libère une configuration correspondant à un premier champ, de sorte que la cohérence des champs appliqués par le dispositif terminal et un second dispositif réseau est maintenue, et le dispositif terminal peut ainsi effectuer une communication normale dans le cadre du second dispositif réseau.
