Abstract

La présente invention concerne, dans le mode de réalisation, décrit, un procédé et un appareil de commande de réception discontinue (DRX). Un équipement d'utilisateur peut observer l'état d'utilisation d'un spectre non autorisé dans une zone où est situé l'équipement d'utilisateur; si l'état observé d'utilisation du spectre non autorisé est un état d'occupation, alors les informations d'occupation du spectre non autorisé sont obtenues, et un message d'indication véhiculant les informations d'occupation est envoyé à une station de base, suivi de l'entrée sous contrôle dans une période dormante de DRX, la station de base, d'après le message d'indication véhiculant les informations d'occupation, désactivant ainsi la programmation de l'équipement d'utilisateur dans le spectre non autorisé dont l'état d'utilisation est l'état d'occupation; et lorsque l'état d'utilisation du spectre non autorisé est l'état d'occupation, l'équipement d'utilisateur entre dans la période dormante de DRX, et pendant ce temps, il n'existe plus de programmation de l'équipement d'utilisateur dans le spectre non autorisé par la station de base, ce qui a pour effet de rendre cohérentes une période active de DRX et la durée de disponibilité du spectre non autorisé, d'améliorer le taux d'utilisation du spectre non autorisé et de diminuer la consommation énergétique de l'équipement d'utilisateur.
