Abstract

La présente demande concerne le domaine technique des communications. Sont divulgués un procédé et un appareil de communication, un dispositif terminal, un nœud primaire et un nœud secondaire. Le procédé consiste en : l'envoi par un dispositif terminal de premières informations, les premières informations étant utilisées pour mettre à jour des informations historiques du dispositif terminal qui sont stockées dans une première cellule secondaire primaire (PSCell) dans des changements de PSCell conditionnels continus, la première PSCell étant une PSCell à laquelle le dispositif terminal accède ou a accédé; et de manière correspondante, un nœud secondaire reçoit les premières informations. Dans les modes de réalisation de la présente demande, des premières informations sont introduites et des informations historiques d'un dispositif terminal qui sont stockées dans une première PSCell sont mises à jour dans des changements de PSCell conditionnels continus au moyen des premières informations. De cette manière, à chaque fois qu'un dispositif terminal accède ou a accédé à une nouvelle PSCell, des informations historiques stockées dans la nouvelle PSCell sont mises à jour au moyen de premières informations, ce qui permet d'assurer la stabilité, la fiabilité et la précision de communication à double connectivité dans des conditionnels continus de PSCell.
