PROBLEM TO BE SOLVED: To restart interrupted data transmission only when data, which a server device has, is not updated in case that the data transmission from the server device is interrupted. SOLUTION: When the data transmission, which transmits data WWW server 16 has to DTE 11 via LWP 15, is interrupted, the DTE 11 stores a part already received, the LWP 15 compares already-received part information obtained from the DTE 11 and update information received from the WWW server 16 in response to data transmission restart request from the DTE 11, and transmits only a part the DTE 11 does not still receive to the DTE 11 only when both are identical, and the DTE 11 obtains data by connecting the part already received and the part unreceived.
