Abstract

L'invention concerne un terminal et un procédé de protection contre les chutes. Le procédé de protection contre les chutes comprend : la détection si un terminal vibre ou non ; si le terminal vibre, la transmission, par le terminal, d'un signal de test ; et la détection si un paramètre de réflexion du signal de test a changé ou non et, si c'est le cas, l'arrêt de la vibration du terminal. Le procédé peut arrêter la vibration du terminal à temps lorsque le terminal se déplace hors de la surface d'un objet où le terminal est placé du fait de la vibration, de sorte que le terminal soit protégé d'une chute au cours de la vibration, évitant ainsi un endommagement du terminal.
