  • the delay-insensitive terminal when the base station load is not heavy, the delay-insensitive terminal is switched to the active state again, thereby improving the utilization of network resources. Therefore, the scheduling system provided by the embodiment of the present invention is also within the protection scope of the embodiment of the present invention.

Abstract

La présente invention concerne un procédé, un appareil et un système permettant une commutation d'état. Le procédé comprend les étapes consistant à : déterminer un terminal comme étant un terminal insensible au retard temporel; lorsque la charge d'une station de base dépasse une première valeur de seuil de charge définie par un dispositif côté réseau, passer l'état du terminal insensible au retard temporel d'un état activé à un état inactivé; et lorsque la charge de la station de base est réduite, si la charge de la station de base est inférieure à une seconde valeur de seuil de charge définie par le dispositif côté réseau, passer l'état du terminal insensible au retard temporel de l'état inactivé à l'état activé. Les modes de réalisation de la présente invention permettent d'économiser des ressources de calcul de programmation et des ressources de réseau pour la station de base par la réduction de la quantité d'UE (équipements utilisateurs) dans l'état activé.
