Abstract

La présente invention concerne, dans certains modes de réalisation, un procédé et dispositif de commande de réception discontinue. Le procédé consiste à : acquérir une requête d'exécution pour exécuter un processus spécifique, le processus spécifique changeant une durée en un état actif de réception discontinue (DRX) d'un terminal; ajuster, selon des informations de commande correspondant au processus spécifique, la durée de l'état actif de la DRX du terminal; et notifier à une première station de base et/ou à une seconde station de base l'ajustement, la première station de base et la seconde station de base étant toutes deux connectées au terminal. Les modes de réalisation de la présente invention abordent le problème de l'état de la technique dans lequel une durée d'un état actif de DRX n'est pas ajustable lorsqu'une agrégation de porteuses est réalisée entre des cellules sous différentes stations de base, permettant ainsi l'ajustement de la durée de l'état actif de DRX lorsqu'une agrégation de porteuses est réalisée entre des cellules sous différentes stations de base.
