Abstract

L'invention concerne un procédé de détermination d'une cellule, comprenant les étapes consistant : à envoyer une instruction de mesure de signal à un UE par l'intermédiaire d'un point de fréquence de mesure cible, l'instruction de mesure de signal étant utilisée pour ordonner à l'UE d'acquérir des informations de qualité de signal concernant au moins une cellule de mesure correspondant à un point de fréquence sans licence, et le point de fréquence sans licence ayant une corrélation avec le point de fréquence de mesure cible ; à recevoir les informations de qualité de signal, rapportées par l'UE, concernant lesdites cellules de mesure ; à sélectionner une cellule de mesure cible en fonction des informations de qualité de signal concernant lesdites cellules de mesure ; et à déterminer une cellule d'accès cible correspondant à la cellule de mesure cible selon une corrélation de cellule prédéfinie, les cellules de mesure et les cellules d'accès dans la corrélation de cellule prédéfinie étant en correspondance biunivoque. L'invention concerne en outre une station de base, un UE et un système. Dans la présente invention, il n'est pas nécessaire d'émettre de manière répétée une instruction de mesure de signal, ce qui simplifie la signalisation, et une station de base peut toujours déterminer une cellule d'accès appropriée selon une corrélation de cellule prédéfinie même lorsqu'un UE est dans un état de déplacement, améliorant ainsi le taux de réussite pour la station de base afin de sélectionner une cellule d'accès appropriée.
