Abstract

La présente demande se rapporte au domaine des communications mobiles. La présente demande concerne un procédé et un appareil de transmission de données, ainsi qu'un dispositif et un support de stockage. Le procédé comprend les étapes suivantes : lorsqu'un terminal est dans un état inactif de commande de ressources radio (RRC), le terminal reçoit des premières informations de ressource configurées par un dispositif réseau, les premières informations de ressource étant utilisées par le terminal pour transmettre des données de liaison montante dans l'état inactif RRC ; et transmet les données de liaison montante d'après les premières informations de ressources. Il n'est pas nécessaire de passer d'un état inactif RRC à un état connecté RRC pour transmettre des données de liaison montante, ce qui simplifie le processus de transmission des données de liaison montante par un terminal lorsque le terminal est dans l'état inactif RRC, et réduit ainsi le surdébit de signalisation.
