Abstract

L'invention concerne un appareil de communication mobile qui comprend : une unité de détection de conditions anormales qui détecte les conditions anormales, le cas échéant, sur un chemin ; et une unité de communication qui comprend une unité de détermination et qui, si l'unité de détermination détermine que la transmission d'un message de détection indiquant une condition anormale détectée par l'unité de détection de conditions anormales est nécessaire, transmet le message de détection et qui reçoit un message informatif indiquant une condition anormale détectée par une unité de détection d'un appareil externe. Quand l'unité de détection de conditions anormales détecte la condition anormale, l'unité de détermination détermine si la condition anormale détectée est identique à la condition anormale indiquée par le message informatif. Si la condition anormale détectée est différente de la condition anormale indiquée par le message informatif, l'unité de détermination détermine que la transmission du message de détection est nécessaire.
