Abstract

L'invention concerne un procédé et un appareil de conversion de mode de fonctionnement pour dispositifs de réseau à double connectivité, lesdits procédé et appareil étant appliqués à un premier dispositif de réseau. Le procédé comprend les étapes consistant à : déterminer si une condition de déclenchement permettant une conversion d'un mode de fonctionnement est satisfaite ; en réponse à la satisfaction de la condition de déclenchement permettant la conversion du mode de fonctionnement, envoyer une demande de conversion du mode de fonctionnement à un second dispositif de réseau ; et envoyer à un terminal connecté au second dispositif de réseau des premières informations d'indication utilisées pour indiquer la conversion du mode de fonctionnement. Les modes de fonctionnement comptent un premier mode de fonctionnement et un second mode de fonctionnement. Le premier mode de fonctionnement est un mode de fonctionnement sans économie d'énergie. Le second mode de fonctionnement est un mode de fonctionnement à économie d'énergie. Dans le procédé décrit, lorsque le second dispositif de réseau entre dans un des modes de fonctionnement, les paramètres de configuration stockés du terminal n'ont pas à être supprimés. De plus, lorsque le second dispositif de réseau entre dans l'autre mode de fonctionnement, le délai temporel nécessaire au terminal pour accéder au second dispositif de réseau lorsque le second mode de fonctionnement est remplacé par le premier mode de fonctionnement est réduit, ce qui à son tour contribue à augmenter le débit de transmission de données entre le terminal et les dispositifs de réseau.
