Abstract

L'invention concerne un procédé et un appareil de sélection de réseau sur la base d'un code de pays. Le procédé comporte les étapes consistant : après qu'un terminal sans fil a démarré et obtenu un code de pays pour mobiles, à déterminer si un code de pays pour mobiles d'un réseau est un code de pays pour mobiles d'un pays particulier; et lorsque le code de pays pour mobiles du réseau est le code de pays pour mobiles du pays particulier, un mode de recherche de réseau étant un mode automatique bimode, à spécifier le mode de recherche de réseau comme étant un mode 3G uniquement. Par comparaison à la technique antérieure, en utilisant le procédé et l'appareil de la présente invention, une restriction qui fait qu'un terminal sans fil ne peut réaliser une recherche mondiale que selon des gammes de fréquence est levée, et la détermination peut être effectuée en fonction de codes de pays pour mobiles de façon à réaliser un réglage dynamique, raccourcissant ainsi le temps de recherche d'un réseau; en même temps, le signalement d'informations inutiles peut être évité, et le fonctionnement normal du terminal sans fil dans un mode peut être garanti.
