Abstract

L'invention concerne un procédé et un système relatifs au processus de mise à niveau de micrologiciel de terminal mobile. Le procédé est le suivant : le terminal mobile télécharge une version de micrologiciel améliorée et stocke la sauvegarde de la version de micrologiciel courante dans sa mémoire (S402). Le terminal mobile effectue une mise à jour du micrologiciel et met à jour la version courante du micrologiciel par rapport à la version améliorée (S404). Selon la présente invention, la version est sauvegardée, le retour à la version désuète pouvant être effectué lorsque surviennent des pannes et des accidents en relation avec la mise à niveau de sorte que les utilisateurs puissent revenir à la version de sauvegarde originale à tout moment afin d'éviter tout problème désastreux entraînant la non utilisation du terminal après la mise à niveau, ce qui permet de garantir une mise à niveau de micrologiciel sûre et fiable. En outre, lorsque l'opération de mise à niveau de micrologiciel a échoué en grande partie, l'utilisateur est assuré de pouvoir revenir rapidement à la version de sauvegarde de façon à éviter des coûts élevés générés par le département d'exploitation et de maintenance du fournisseur ou le département service client du fabricant et à réduire les coûts de fonctionnement et de maintenance du dispositif.
