Abstract

La présente invention concerne un procédé de mesure de gestion des ressources radio, un appareil et un support de stockage. Dans le procédé, s'il est déterminé qu'un terminal répond à une condition de déclenchement prédéfinie quand il est dans un état connecté, le terminal effectue une mesure de gestion des ressources radio (RRM). Le procédé réduit le retard dans un processus de rétablissement RRC effectué par le terminal après une défaillance de liaison radio, et utilise une condition de déclenchement prédéfinie pour limiter les mesures RRM effectuées dans l'état connecté, réduisant ainsi le nombre de mesures RRM effectuées dans l'état connecté, et réduisant en conséquence la consommation d'énergie du terminal.
