Abstract

Les modes de réalisation de la présente invention concernent un dispositif d'appel d'urgence montés sur véhicule et un procédé associé, servant à résoudre les problèmes rencontrés par un centre de sauvetage d'urgence lorsqu'il ne peut pas acquérir un MSD en raison de la défaillance de l'état de service actuel d'un réseau sans fil et du manque de probabilité pour que le centre de sauvetage d'urgence acquière un MSD correctement en raison de la mauvaise qualité d'un signal de réseau sans fil. La solution spécifique comprend les étapes consistant à : acquérir un MSD ; et lorsqu'il est déterminé que la fonction de communication sans fil d'un appareil eCall monté sur un véhicule présente une défaillance, envoyer le MSD à un dispositif auxiliaire au moyen d'un module de communication à courte distance, afin que le dispositif auxiliaire envoie le MSD à un serveur. Les modes de réalisation de la présente invention sont utilisés lorsqu'un appareil eCall monté sur véhicule émet un appel d'urgence.
