Abstract

L'invention concerne un procédé, un dispositif et un système d'instruction pour effectuer des mesures sur terminal MDT afin d'améliorer le mécanisme de mesure sur terminal MDT de l'art antérieur. Le procédé comprend les étapes suivantes : après qu'une entité MME a déterminé qu'un équipement utilisateur (UE) accédait à une cellule gérée par un nœud eNB, envoyer des paramètres de configuration de mesures MDT au nœud eNB, le nœud eNB déterminant si l'UE se trouve en deçà d'une distance de mesure MDT spécifiée; si oui, délivrer les paramètres de configuration de la mesure MDT et sinon, ne pas délivrer les paramètres de configuration de la mesure MDT. Ainsi, lorsqu'un UE respectant une condition de sélection OAM ne se trouve pas en deçà de la distance de mesure MDT spécifiée, le nœud eNB ne peut pas délivrer les paramètres de configuration de la mesure MDT, cela réduisant ainsi le surdébit de signalisation; lorsque l'UE se déplace et se trouve en deçà de la distance de mesure MDT spécifiée, le nœud eNB délivre les paramètres de configuration de mesure MDT à l'UE, afin de faire en sorte que l'UE puisse effectuer des mesures MDT et les signaler en temps utile, cela garantissant de bonnes performances du système et une bonne qualité de service. Par ailleurs, la présente invention concerne un dispositif et un système correspondants.
