Abstract

La présente invention concerne un appareil et un procédé de détection de point de fréquence anormale, et un support d'informations informatique, le procédé comprenant les étapes suivantes : lors de la réception d'un message de radiomessagerie CS, un terminal balaye le point de fréquence d'une pluralité de cellules GSM ; sur la base des résultats de balayage, le terminal détermine le point de fréquence d'une cellule GSM cible, et utilise le point de fréquence de la cellule GSM cible comme un point de fréquence cible pour une communication ; sur la base du point de fréquence cible, le terminal envoie un message de demande de canal RR au réseau et active un premier temporisateur pour attendre un message IA renvoyé par le réseau ; lors de la non-réception d'un message IA renvoyé par le réseau avant que le premier temporisateur s'écoule, le terminal détermine si un paramètre dans un message de diffusion de système satisfait une condition prédéfinie ; et lorsque le paramètre dans le message de diffusion de système ne satisfait pas la condition prédéfinie, déterminer que le point de fréquence cible constitue une fréquence anormale.
