Abstract

L'invention concerne un procédé et un dispositif de conversion de support radio de données (DRB), le procédé consistant : en ce qu'un équipement d'utilisateur (UE) reçoit une requête de modification de support de données envoyé par un premier eNode B, la requête de modification de support de données portant des informations de configuration du premier DRB sur un second eNode B obtenues du second eNode B, le premier DRB ayant été établi sur le premier eNode B ; en ce que l'UE retire temporairement le premier DRB sur le premier eNode B, et retient une relation de mappage entre le premier DRB sur le premier eNode B et un support de système de paquets évolué (EPS) ; en ce que l'UE établit le premier DRB sur le second eNode B en fonction des informations de configuration. La présente invention résout le problème de l'état de la technique de la manière de convertir différents types de DRB, améliorant ainsi la flexibilité de l'usage de DRB.
