Abstract

La présente invention concerne un procédé et un dispositif fonctionnant dans un nœud de communication sans fil. Un premier nœud reçoit des premières informations puis une première signalisation. Les premières informations contiennent K éléments d'informations de configuration destinés à une première cellule de service. Un premier ensemble d'informations de configuration contient K1 éléments d'informations de configuration parmi les K éléments d'informations de configuration. La première signalisation est utilisée pour activer K2 éléments d'informations de configuration dans le premier ensemble d'informations de configuration et pour indiquer que seuls les K2 éléments d'informations de configuration dans le premier ensemble d'informations de configuration sont dans un état actif. K est un entier positif supérieur à un. K1 est un entier positif supérieur à un et inférieur à K. K2 est un entier positif inférieur à K1. Lorsqu'un UE est configuré par une pluralité de configurations d'autorisations configurées, le procédé d'après la présente invention réduit le surdébit de signalisation requis pour activer/libérer lesdites configurations.
