Abstract

L'invention concerne un procédé et un appareil de configuration de mesure de relation de voisins automatique (ANR). Le processus d'instruction de mesure d'identité globale de cellule (CGI) selon l'invention consiste : à recevoir un rapport de mesure rapporté par un terminal, le rapport de mesure véhiculant une fréquence et une identité de cellule physique (PCI) mesurée par le terminal ; à déterminer, pour le terminal, une fréquence utilisée pour effectuer une mesure de CGI sur la PCI, et à configurer, pour le terminal selon la fréquence déterminée, un groupe de fréquences utilisé pour une mesure de CGI ; à donner l'instruction au terminal d'effectuer une mesure de CGI selon la PCI et le groupe de fréquences. Le processus de configuration de mesure de cellule la plus forte, selon l'invention, consiste : à acquérir des informations statistiques d'une mesure de cellule la plus forte pour un terminal ; à régler, selon les informations statistiques, un groupe de fréquences utilisé pour effectuer une mesure de cellule la plus forte sur le terminal ; à donner l'instruction au terminal d'effectuer une mesure de cellule la plus forte selon le groupe de fréquences réglé.
