Abstract
The present application discloses a file transfer system, a policy server, a terminal, and a file transfer method. The file transfer system includes a file sending terminal, a file receiving terminal, the policy server, and a file server. The file sending terminal is configured to acquire and report a unique identifier of a file to be transferred to the file receiving terminal; the policy server is configured to query, according to the unique identifier, whether the file server stores a backup file same as the file to be transferred; and when the file server stores the backup file, the policy server is further configured to indicate transfer of the backup file from the file server to the file receiving terminal. The present application enables a file receiving terminal to acquire a file to be transferred at a transfer speed corresponding to a downlink bandwidth of the file receiving terminal, so as to accelerate a process of file transfer between terminals.
