PORTABLE TERMINAL APPARATUS, METHOD FOR CONTROLLING PORTABLE TERMINAL APPARATUS, COMMUNICATION SYSTEM, COMMUNICATION APPARATUS, AND METHOD FOR CONTROLLING COMMUNICATION APPARATUS

摘要

Data transmission between a server and a communication apparatus via a portable terminal apparatus is performed at a high speed. The portable terminal apparatus is provided with: a first communication means which is connected to the server in the network and performs data communication; a second communication means which is connected to the communication apparatus and performs data communication; a temporary storage means which temporary stores data at the time of relaying data communication between the server and the communication apparatus using the first communication means and the second communication means; and a control means which controls the data communications performed by the first communication means and the second communication means asynchronously and in parallel at the time of relaying the data communication between the server and the communication apparatus.
