A session opening request is made (S401). The middleware 22 that has received the session opening request sends the device target I
The device information management table 9 is searched based on D51, and the IP address 54 of the corresponding device is obtained (S402).
A session opening request is transmitted to the communication terminal device 30 based on the acquired IP address 54 (S403). Communication channel 1
The middleware 32 on the receiving side that has received the session opening request via the server application 041 generates a unique session ID on the middleware 32, and the application 3 on the receiving side.
