Abstract

L'invention concerne un procédé, un appareil et un système de mise à jour d'un identificateur de mesure. Le procédé consiste : en la détermination, par un dispositif terminal, si un identificateur de cible de mesure correspondant à une fréquence à laquelle se trouvent des cellules principale et secondaire cibles figure ou non dans une liste de cibles de mesure d'une variable de configuration de mesure mémorisée par le dispositif terminal lorsqu'une fréquence à laquelle se trouvent ses cellules principale et secondaire est modifiée; et si l'identificateur de cible de mesure correspondant à la fréquence à laquelle se trouvent des cellules principale et secondaire cibles figure dans la liste de cibles de mesure, alors en la mise à jour, par le dispositif terminal, une configuration d'un identificateur de mesure relatif à une fréquence à laquelle se trouvent des cellules principale et secondaire sources et les cellules principale et secondaire cibles. Le procédé évite une fin non nécessaire de la mesure d'un terminal provoquée par le changement de cellules principale et secondaire et de leur fréquence, fournit plus de référence pour la gestion de ressources sans fil d'une station de base cible, et réduit la charge de signalisation ajoutée par continuation d'une configuration de mesure dans le scénario susmentionné.
