Abstract

La présente invention porte, selon certains modes de réalisation, sur un procédé de transmission de message et sur un dispositif associé. Le procédé consiste : à configurer, au moyen d'un dispositif de réseau, une première ressource pour un dispositif terminal, la première ressource étant une ressource préconfigurée ; à déterminer, au moyen du dispositif de réseau, un premier signal d'activation lorsque le dispositif terminal est dans un état inactif, le premier signal d'activation étant utilisé pour indiquer que le dispositif terminal peut ou ne peut pas utiliser la première ressource destinée à envoyer des informations de liaison montante ; et à envoyer, au moyen du dispositif de réseau, le premier signal d'activation au dispositif terminal dans un état inactif. Un nouveau procédé de notification est fourni afin de notifier au dispositif terminal dans un état inactif d'utiliser ou de ne pas utiliser la ressource préconfigurée.
