Abstract

La présente invention concerne un procédé et un dispositif d'émission et de transmission de données ou de signalisation, faisant intervenir les étapes consistant à: déterminer, du côté d'un terminal, que des données ou une signalisation doivent être émises par un UE dans un état inactif; envoyer les données ou la signalisation à une station de base dans l'état inactif. Du côté de la station de base, la station de base reçoit des données ou une signalisation émises par un UE dans un état inactif; et envoie des données ou une signalisation à un réseau central selon les informations de contexte de l'UE. L'utilisation de la présente invention peut réduire la surcharge de signalisation dans le scénario de petites données éparses et accroître le taux d'utilisation des ressources pour l'opérateur. En plus de réduire la surcharge de signalisation, la transmission de données ou de signalisation peut être plus rapide, car des données ou une signalisation peuvent être émises sans passer par le processus d'émission après la transition d'état du processus de signalisation.
