Abstract

La présente invention concerne un procédé et un système pour limiter l'utilisation d'un terminal. La présente invention peut comprendre les étapes qui sont exécutées par un terminal d'un membre appartenant à un groupe particulier et qui consistent : à recevoir une commande de verrouillage provenant d'un serveur ; à s'enquérir s'il faut accepter ou non une commutation dans un état de verrouillage, avant la commutation du terminal membre dans l'état de verrouillage, sur la base d'informations de configuration de verrouillage comprises dans la commande de verrouillage ; à commuter le terminal membre dans l'état de verrouillage si une indication d'acceptation, en réponse à la demande de renseignement, est saisie dans le terminal membre ; à libérer l'état de verrouillage du terminal membre sur la base des informations de configuration de verrouillage. Selon la présente invention, l'utilisation de terminaux de communication d'information de membres appartenant à un groupe particulier, tel qu'une école ou une entreprise, peut être limitée efficacement pendant une durée prédéterminée.
