Abstract

La présente invention concerne un procédé, un dispositif et un système de commande de transmission, le procédé consistant à : faire en sorte qu'un dispositif terminal transmette une requête à un côté réseau pour interrompre la transmission montante et/ou la transmission descendante du dispositif terminal, la demande étant utilisée par le côté réseau pour déterminer s'il est nécessaire de transmettre une instruction pour ordonner au dispositif terminal d'arrêter la transmission montante et/ou la transmission descendante. Au moyen de ce procédé, un UE (Equipement Utilisateur) transmet une demande d'interruption de la transmission montante/descendante à un côté réseau, cela permettant au côté réseau de déterminer plus précisément s'il est nécessaire de commander l'UE afin d'interrompre la transmission montante et/ou descendante, pour que l'UE puisse effectuer des économies d'énergie.
