SOLUTION: When a server side transport protocol 11 receives a confirmation response from a client side transport protocol 21, the server side transport protocol 11 writes charging information to data of a transmitted packet in a charging information accumulating means 13. Then, the server side transport protocol 11 transmits a key for decoding the data of the packet that has been enciphered and is transmitted to the client side transport protocol 21 mentioned earlier. The client side transport protocol 21 which receives the key decodes the data of the packet on the basis of the key and transfers the decoded data to a client side application program 20.
