Abstract

La présente demande concerne un procédé de traitement, un dispositif de communication et un support d'enregistrement. Le procédé de traitement comprend les étapes suivantes consistant à : déterminer au moins une ressource disponible ; et lancer une activation SCG à l'aide de la ressource disponible. Dans la solution technique de la présente demande, une ressource disponible est préconfigurée pour un UE, puis, sans qu'il soit nécessaire d'attendre une instruction d'un MN, l'UE lance une activation SCG sur un SCG désactivé à l'aide de la ressource disponible préconfigurée, ce qui permet d'économiser le temps d'activation du SCG et de réduire davantage un délai de transmission de données du SCG.
