Patent ID: 7606243

Claim:
A terminal device, comprising: a first interface configured to carry out at least a packet transmission with respect to a first network which is a radio network according to IEEE 802.11; a second interface configured to carry out packet transmission and reception with respect to a second network which is a radio network slower than the first network; and a control unit configured to carry out communications with another terminal through the second interface so as to carry out a prescribed procedure required in using the another terminal as a receiving side in the first network, and transmit a prescribed information to the first network on behalf of the another terminal, the prescribed information being an information to be transmitted to the first network by the another terminal, the another terminal having no transmission function with respect to the first network, wherein the control unit also receives a packet transmission request with respect to the first network from the another terminal through the second interface through the second network, the prescribed procedure being initiated by the packet transmission request transmitted by the another terminal, and wherein the control unit also transmits through the first network another packet transmission request corresponding to the packet transmission request received from the another terminal and requesting packet transmission from a source terminal being directly connected to the first network to the terminal device, when the source terminal is indicated in the packet transmission request received from the another terminal, receives through the first network packets corresponding to the another packet transmission request and transmitted from the source terminal, and transfers the packets received from the source terminal to the another terminal through the first interface through the first network.
