Abstract

L'invention divulgue des systèmes et des procédés pour mettre à jour des paramètres de commande d'alimentation d'équipement utilisateur (UE) pour une transmission de petits volumes de données à autorisation configurée (CG-SDT). Dans un mode de réalisation, un procédé effectué par un UE consiste à recevoir une configuration CG-SDT en provenance d'un nœud de réseau. Le procédé consiste en outre, pendant que l'UE est dans un état inactif, à recevoir, en provenance du nœud de réseau, des informations qui indiquent un ou plusieurs paramètres de configuration CG-SDT mis à jour. De cette manière, des mises à jour de commande d'alimentation peuvent être effectuées de manière efficace pour CG-SDT. L'invention divulgue également des modes de réalisation correspondants d'un UE. Des modes de réalisation d'un nœud de réseau et leurs procédés de fonctionnement sont également divulgués.
