Abstract

Cette invention concerne un dispositif et un procédé permettant de recevoir directement un message électronique et son annexe (par exemple fichier Doc, fichier Hwp, fichier Gul ou fichier Ppt) à la demande via un terminal sans fil. Selon ce procédé, le gestionnaire d'interface de serveur de courrier électronique reçoit le message d'analyse et accède au serveur de courrier électronique par l'intermédiaire d'un agent d'accès audit serveur et d'un agent de base de données au moyen d'un protocole déterminé. Le gestionnaire d'interface de serveur de courrier électronique transmet ensuite le message électronique et ses annexes dans le serveur de courrier à un gestionnaire de format interne. Ce gestionnaire de format interne convertit les différents formats du message électronique et ses annexes en un format interne défini antérieurement. Un convertisseur de fichiers convertit ce format intérieur en un format susceptible d'être reconnu par le terminal sans fil et transmet le message électronique et ses annexes converties au terminal sans fil. Si l'utilisateur met un terme à l'opération de réception au moyen du terminal sans fil, le module de serveur mandataire HTTP clôt l'accès, efface le message électronique et ses annexes du terminal sans fil jusqu'au prochain message de demande. Ainsi tout utilisateur de terminal sans fil peut recevoir n'importe quel type de message électronique et d'annexe via son terminal mobile.
