Abstract

La présente invention concerne un procédé et un appareil de transmission, de réception et de transfert de données. Le procédé consiste à : transmettre des données de liaison montante à une station de base de desserte actuelle au moyen d'un support radio dans un état inactif, lors de la transmission de données de liaison montante ; recevoir, sur une station de base, les données transmises par un équipement d'utilisateur (UE) dans un état inactif, au moyen du support radio, la station de base étant une station de base de desserte actuelle de l'UE ; et transmettre les données à un nœud de réseau central ; lors de la transmission de données de liaison descendante, transmettre les données à la station de base de desserte actuelle de l'UE, sur une station de base d'ancrage ; transmettre les données à l'UE dans un état inactif au moyen du support radio sur la station de base de desserte ; recevoir les données transmises par la station de base de desserte actuelle au moyen du support radio au niveau de l'UE dans un état inactif. La solution selon l'invention réduit la complexité d'un processus de signalisation dans un scénario de transmission de petites données non communes et améliore le taux d'utilisation des ressources des opérateurs. Outre la réduction de la complexité du processus de signalisation, le transfert de données peut être effectué plus rapidement du fait que la transmission de données n'exige pas un processus de signalisation initial pour effectuer la transition d'état préalablement à la transmission.
