Abstract

L'invention concerne un procédé, un dispositif et un système servant à commander un UE pour lui faire exécuter des mesures, le procédé comprenant les étapes suivantes : un RNC envoie à un UE des informations de configuration de mesure d'ANR ; l'UE effectue des mesures d'ANR d'après les informations de configuration de mesure d'ANR et enregistre les résultats de mesure ; lorsqu'une antémémoire servant à enregistrer les résultats de mesure est pleine, l'UE envoie un message d'instruction au RNC ; lorsque le RNC reçoit le message d'instruction, le RNC envoie à l'UE un message de demande d'ANR ; lorsque l'UE reçoit le message de demande d'ANR, l'UE rapporte le résultat de mesure enregistré. La solution technique présentée dans la présente invention résout le problème de l'art antérieur du manque de procédé de signalisation spécifique pour le cas où l'antémémoire d'UE servant à enregistrer les résultats de mesure est pleine, ce qui garantit la signalisation en temps opportun des résultats de mesure.
