Abstract

La présente invention concerne un procédé et un système destinés à obtenir une capacité de mesure multiporteuse supportée par un équipement utilisateur (UE). Dans le procédé de la présente invention, l'UE déclare sa capacité de mesure multiporteuse supportée au côté réseau, puis le côté réseau obtient les informations de capacité de mesure multiporteuses, supportée par l'UE, il est ainsi garanti que le côté réseau détermine s'il faut initier un mode compressé et comment configurer le contrôle de mesure, comme le paramètre de mode compressé, selon la capacité de mesure multiporteuse obtenue supportée par l'UE. L'UE exécute une mesure correspondante selon le contrôle de mesure afin que l'UE ne puisse pas changer la cellule de desserte à temps, du fait qu'une fausse détection de porteuse secondaire par l'UE est évitée et que la continuité d'un appel est garantie.
