Abstract

L'invention concerne un système et un procédé (10) destinés à améliorer le fonctionnement d'un téléphone sans fil lors de situations d'urgence. Le système place le téléphone sans fil dans un état (12) de rappel d'urgence lorsqu'un appel d'urgence est émis par le téléphone sans fil. Le système gère alors le téléphone pour répondre automatiquement (18) à un appel entrant lorsque le téléphone sans fil se trouve dans l'état de rappel d'urgence. Dans un mode de réalisation spécifique, l'état de rappel d'urgence est caractérisé par des réglages de volume forts du téléphone sans fil. Dans l'état de rappel (12), une modification des réglages de desserte du réseau n'est pas autorisée et l'utilisation du téléphone sans fil est limitée uniquement à l'envoi d'appels d'urgence. On peut sortir du mode d'appel d'urgence en appuyant sur le bouton FIN. Le second mécanisme comprend un logiciel se déroulant sur un ordinateur contenu dans le téléphone sans fil. Le logiciel comprend des commandes de réponse automatique du téléphone sans fil après un nombre prédéterminé de sonneries.
