Abstract

La présente invention concerne un procédé et un dispositif pour la transmission de données, un dispositif sur le côté réseau, et un terminal. Le procédé comprend : l'allocation, par un dispositif sur le côté réseau, d'un premier identifiant pour un terminal et l'envoi du premier identifiant au terminal; l'identification unique du terminal par le premier identifiant; la réception, par le dispositif sur le côté réseau, d'un premier message de commande envoyé par le terminal, le premier message de commande étant envoyé quand des données sur la liaison montante doivent être transmises sur le terminal et le terminal étant dans un état de désactivation et ayant libéré un C-RNTI du terminal; la programmation d'une ressource pour le terminal par le dispositif sur le côté réseau quand il est déterminé que le premier message de commande contient le premier identifiant; et l'envoi du premier message de commande reçu au terminal, par le dispositif sur le côté réseau, sur la ressource d'accès programmée. Le terminal peut ainsi résoudre le problème de résolution de conflit d'accès sur la base du premier message de commande, et exécuter la transmission des données sur la liaison montante. La présente invention est apte à atténuer le problème de contrainte sur des ressources RNTI.
