Abstract

L'invention concerne un procédé mis en oeuvre au niveau d'un équipement utilisateur. Le procédé consiste à stocker une pluralité de profils générés pendant au moins une connexion de l'équipement utilisateur avec un réseau d'accès radio, chaque profil comprenant un ensemble de paramètres d'au moins une configuration de commande de ressource radio de l'équipement utilisateur. Le procédé consiste à maintenir la pluralité de profils stockés dans un état de repos de l'équipement utilisateur. Le procédé consiste également à restaurer un profil de la pluralité de profils stockés à au moins une configuration de commande de ressource radio pour une connexion actuelle ou ultérieure de l'équipement utilisateur avec le réseau d'accès radio. À cet égard, le profil est restauré sur la base de l'échange d'un identifiant de profil du profil avec le réseau d'accès radio. L'invention concerne également un procédé mis en oeuvre au niveau d'un nœud d'accès radio d'un réseau d'accès radio.
