Abstract

Les modes de réalisation de la présente demande concernent un procédé de surveillance d'un signal de réveil, un dispositif terminal et un dispositif de réseau. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des informations de configuration envoyées par un dispositif de réseau, les informations de configuration comprenant une pluralité de configurations de réception discontinue (DRX) correspondant à une entité de commande d'accès au support (MAC) du dispositif terminal ; et selon que les périodes d'activation de la pluralité de configurations DRX chevauchent une occasion de surveillance d'un signal de réveil (WUS), le dispositif terminal détermine s'il faut surveiller le WUS. Au moyen du procédé de surveillance d'un signal de réveil, du dispositif terminal et du dispositif de réseau dans les modes de réalisation de la présente invention, la consommation d'énergie d'un dispositif terminal peut être efficacement réduite lorsqu'une pluralité de configurations DRX sont configurées.
