Method and device for data relaying

A data-relaying device used for a method of relaying data between a first terminal device connected to a first network and a second terminal device connected to a second network, said data-relaying device comprising:

• means for receiving location information of at least either one of said first terminal device or said second terminal device;
• means for storing said location information;
• means for receiving data upon data communication between said first terminal device and said second terminal device;
• means for searching in said storing means based on location information accompanying said data received from said first terminal device;
• means for converting said location information accompanying said data if said location information exists in said storing means as a result of said searching, so that said location information stored in said storing means becomes a new location information of said data;
• and
• means for sending said data accompanied with said location information having been converted to said second terminal device.

A method of relaying data between a first terminal device connected to a first network and a second terminal device connected to a second network, said method comprising:

• searching in a storing device based on location information accompanying data received from said first terminal device or said second terminal device, said storing device storing location information indicative of a location of at least said first terminal device;
• as a result of said searching, if said location information exists in said storing device, converting said location information accompanying said data so that said location information stored in said storing device becomes a new location information of said data;
• and
• sending said data accompanied with said location information having been converted to said second terminal device or said first terminal device.

A computer program for relaying data between a first terminal device connected to a first network and a second terminal device connected to a second network, comprising:

• machine-executable code for searching in a storing device based on location information accompanying data received from said first terminal device, said storing device storing location information indicative of a location of at least said first terminal device;
• machine-executable code for converting, if said location information exists in said storing device as a result of said searching, said location information accompanying said data so that said location information stored in said storing device becomes a new location information of said data;
• and
• machine-executable code for sending said data accompanied with said location information having been converted to said second terminal device.
