Abstract

L'invention concerne un procédé, un dispositif et un système de changement de liaison montante. Le procédé comprend les étapes suivantes : si aucune liaison montante de porteuse primaire ou aucune liaison montante de porteuse secondaire n'existe entre un équipement d'utilisateur (UE) et une station de base de non desserte, la détermination que la liaison montante de porteuse primaire ou la liaison montante de porteuse secondaire entre l'UE et la station de base de non desserte nécessite un changement ; et la transmission à la station de base de non desserte d'un message de gestion de liaison radio correspondant au changement, le message de gestion de liaison radio portant les informations indiquant l'état d'activation de la liaison. Le mode de réalisation de l'invention détermine d'abord qu'une liaison montante d'UE nécessite un changement de liaison, et transmet ensuite le message de gestion de liaison radio correspondant au changement de liaison et portant les informations indiquant l'état d'activation de la liaison, ce qui améliore l'efficacité pour un RNC de notifier l'état d'activation de la liaison à un nœud B.
