Also disclosed are the internal structures of the above file relay policy server and IM server and a file transfer method. If the file receiver has not logged in the IM system, it is possible that the file sender sends a file to the file relay policy server, the file relay policy server forwards the file to an appropriate file relay server, and the file relay server transfers the file to a mobile terminal as the file receiver according to a file transfer protocol of the file relay server itself, thereby facilitating the file transfer for the mobile subscriber and enhancing the mobile subscriber's experience in using the mobile IM service."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"File transfer system, device and method","description":"A file transfer system including: a file sender, a file receiver, an Instant Messaging (IM) server, a file relay policy server and a file relay server.
