Abstract

La présente invention concerne un procédé et un appareil de mesure de gestion de ressources radio (RRM). Un dispositif de réseau détermine une condition de mesure relative à une mesure de RRM et notifie la condition de mesure à un terminal. Le terminal effectue une mesure de RRM. Puis, en fonction du résultat de la mesure, il détermine si la condition de mesure est satisfaite et s'il convient d'alléger la mesure de RRM. Autrement dit le terminal peut ajuster de manière flexible le mode de mesure relatif à la mesure de RRM en fonction de la condition de mesure configurée par le dispositif de réseau, c'est-à-dire activer le terminal de façon à effectuer une mesure de RRM en utilisant un mode de mesure de RRM approprié, ce qui facilite une diminution de la consommation d'énergie du terminal.
