Abstract

La présente invention concerne un procédé de gestion d'une session de données entre un serveur de gestion à distance et un agent d'administration de cartes de carte à puce dans un terminal prédéterminé. Le procédé de gestion de session de données comprend les étapes suivantes : la connexion de la session de données entre le serveur de gestion à distance et l'agent; l'ouverture d'une session de transaction de bus série universel entre la carte à puce et le terminal; la réalisation d'un processus de routage IP dans le terminal après une connexion réussie de la session; la distribution de l'information d'état de connexion entre un réseau et le terminal vers l'agent d'administration de cartes; la confirmation des données de la carte à puce s'il n'y a aucune transmission de données pour un certain temps; et enfin, la fin de la session de données.
