Abstract

La présente demande concerne un procédé d'appel d'urgence et un appareil électronique. Le procédé est applicable à des appareils électroniques et consiste à : détecter, pendant qu'un appareil électronique est dans un état d'écran verrouillé, une première opération d'un utilisateur sur un écran d'affichage ; l'appareil électronique affiche, en réponse à la première opération, une interface d'appel d'urgence par l'intermédiaire de l'écran d'affichage, l'interface d'appel d'urgence comprenant un ou plusieurs numéros d'appel d'urgence et des informations de notification, les informations de notification étant utilisées pour notifier qu'un appel à un premier numéro d'appel d'urgence doit être effectué automatiquement après expiration d'une première durée prédéfinie et le ou les numéros d'urgence comprennent le premier numéro d'appel d'urgence ; après expiration de la première durée prédéfinie, réaliser automatiquement un appel vers une station d'alarme si l'appareil électronique ne détecte pas une opération d'utilisateur sur l'écran d'affichage ; et après qu'une connexion d'appel entre l'appareil électronique et la station d'alarme est déconnectée, l'appareil électronique affiche une interface d'écran verrouillé par l'intermédiaire de l'écran d'affichage. Des modes de réalisation de la présente demande facilitent des appels d'urgence rapides pour des utilisateurs dans des conditions d'urgence.
