Abstract

L'invention concerne un procédé permettant de mettre en oeuvre une fonction de protection de secret qui sert à établir des informations de zone limitée pour chaque zone donnée qui applique la fonction limitée d'un terminal mobile et diffuse des informations de zone limitée dans chaque zone donnée. Ledit procédé comprend les étapes: a) de stockage des informations de zone limitée d'une zone donnée dans le terminal mobile à fonction limitée, ledit terminal entrant couramment dans ladite zone donnée, et des informations de zone limitée stockées dans le terminal lui-même correspondant à au moins une information limitée diffusée dans la zone donnée; b) de réception par le terminal mobile des informations diffusées provenant du côté réseau lorsqu'on juge que ledit terminal entre dans la zone limitée en fonction des informations de zone limitée dans les informations diffusées et des informations de zone limitée qu'il stocke, et d'annulation de ses fonctions limitées; c) de restauration dans le terminal mobile de la fonction limitée lorsqu'on détermine qu'il quitte la zone limitée. L'utilisation de cette invention peut donc entraîner l'interdiction temporaire de la fonction limitée dans une zone donnée pour le terminal mobile doté d'une fonction limitée.
