Abstract

La présente demande concerne un procédé, un appareil et un système de mise à jour de données. Le procédé est appliqué à un premier client par liaison radio (OTA) et comprend les étapes suivantes : la réception de données envoyées par un premier serveur OTA sur la base d'informations d'abonnement, les informations d'abonnement indiquant que le premier client OTA a la permission d'utiliser des données dans le serveur OTA ; et l'envoi d'une notification de résultat de mise à jour à un second client OTA, la notification de résultat de mise à jour étant utilisée pour indiquer que le premier client OTA accomplit la mise à jour des données envoyées par le premier serveur OTA, et le premier client OTA et le second client OTA sont configurés sur un même dispositif terminal. Le procédé peut éviter que des données d'un premier serveur OTA soient obtenues par un second serveur OTA.
