Abstract

A system including a first device connected to a network, a second device connected to the network, and at least one portable terminal is disclosed. Device information of the first device containing connection information for establishing a connection between the first device and the second device is transmitted from the first device to the portable terminal and later transmitted from the portable terminal to the second device. Therefore, the connection between the first device and the second device is established based on the device information.

Claims

1. A data transmission device to be used in a system including said data transmission device and a data receiving device which are connected to a data network, and at least one portable terminal, said data transmission device comprising:

a first transmission unit for transmitting to said portable terminal without recourse to said data network a signal for obtaining device information from said data receiving device, the data receiving device information containing connection information for establishing a connection between said data transmission device and said data receiving device;

a receiving unit for receiving the data receiving device information from said portable terminal without recourse to said data network; and

a second transmission unit for transmitting to said data receiving device a signal for starting communication based on the device information using said data network.

2. A data transmission device as claimed in claim 1, wherein the second transmission unit transmits data to said data receiving device via said data network after establishing a connection with said data receiving device.

3. A data transmission device as claimed in claim 1, in which said first transmission unit and said receiving unit transmit and receive data with said portable terminal via a mobile telecommunication network.

4. A data transmission device as claimed in claim 1, in which said connection information contains an identification code for identifying said data receiving device on said data network.

5. A data transmission device as claimed in claim 4, in which said identification code is an IP address.
