Abstract

La présente invention concerne un procédé et un dispositif de partage de conférence pour un document. Le procédé comprend les étapes suivantes : une commande reçoit des informations d'un document à partager à partir d'un programme d'interface Android ; la commande convertit, en fonction des informations du document à partager, le document à partager en un format pouvant être partagé dans un système de conférence ; et le document à partager converti est envoyé à un serveur de conférence pour le partage de conférence. Au moyen de la présente invention, le problème dans l'art connexe de coûts d'extension d'utilisateurs élevés dus à une forte dépendance à l'égard de la capacité de calcul d'un côté serveur pendant un partage de conférence d'un document est résolu, le taux d'occupation des ressources du serveur de conférence est réduit à condition qu'un partage de document commun et une collaboration synchrone dans un environnement de réseau IMS puissent être normalement mis en œuvre, et l'allocation de ressources informatiques est plus raisonnable.
