Abstract

L'invention concerne un procédé et appareil de changement de réseaux pour un terminal à carte multimode. Le code de pays pour mobiles et/ou le code de réseau pour mobiles d'un réseau qu'un terminal recherche est obtenu et, lorsque le code de pays pour mobiles et/ou le code de réseau pour mobiles obtenu coïncide avec le code de pays pour mobiles et/ou le code de réseau pour mobiles figurant dans les informations d'IMSI pré-stockées d'un pays désabonné de la carte multimode, l'IMSI actuellement inscrite de la carte multimode n'étant pas l'IMSI du pays désabonné, l'IMSI actuelle de la carte multimode est changée pour adopter l'IMSI du pays désabonné ou, lorsque le code de pays pour mobiles et/ou le code de réseau pour mobiles obtenu coïncide avec le code de pays pour mobiles et/ou le code de réseau pour mobiles figurant dans les informations d'IMSI pré-stockées d'un pays abonné à la carte multimode, l'IMSI actuellement inscrite de la carte multimode n'étant pas l'IMSI du pays abonné, l'IMSI actuelle de la carte multimode est changée pour adopter l'IMSI du pays abonné, en sorte que le terminal fait passer le réseau de communication au réseau actuel recherché sur la base de l'IMSI changée; par conséquent, le champ d'application de la carte multimode est élargi dans la mesure où le rendement de changement de réseau de la carte multimode est garanti.
