Abstract

La présente invention porte, selon des modes de réalisation, sur un procédé et sur un appareil permettant de coordonner une configuration de mesure, sur un dispositif de réseau et sur un terminal. Le procédé comprend les étapes suivantes : un nœud secondaire reçoit des informations de capacité d'un terminal en provenance d'un nœud primaire, les informations de capacité du terminal étant utilisées pour indiquer si le terminal prend en charge une mesure SFTD ; dans le cas où le terminal prend en charge une mesure SFTD, le nœud secondaire envoie un premier message de notification au nœud primaire en réponse à un changement de cellule secondaire primaire (PScell) qui se produit au nœud secondaire, le premier message de notification étant utilisé pour notifier au nœud primaire le changement qui se produit dans la cellule PScell et/ou pour notifier au nœud primaire des informations d'attribut de la nouvelle cellule PScell modifiée, et les informations d'attribut comportant des informations de point de fréquence et/ou des informations de PCI et/ou des informations d'index de cellule de desserte.
