Abstract

An information processing apparatus and method for a wireless network are provided. The information processing apparatus and method ensure a wide bandwidth by reducing traffic in the wireless network. The information processing apparatus includes a first information storage unit storing router information regarding a wireless network, and an information transmitter transmitting the router information to the mobile terminal contained in the list.

Claims

1. An information processing apparatus for a wireless network, comprising:

a list storage unit storing a list containing information of a mobile terminal sending a router information request message regarding the wireless network;

a first information storage unit storing router information regarding the wireless network; and

an information transmitter transmitting the router information to the mobile terminal contained in the list.

2. The information processing apparatus of claim 1, wherein the list comprises an address of the mobile terminal sending the router information request message, an ID of the router information request message, and a time when the router information request message is received.

3. The information processing apparatus of claim 2, wherein the router information request message is received from a mobile terminal within 1-hop distance from the information processing apparatus.

4. The information processing apparatus of claim 3, wherein the router information is received from a mobile terminal within 1-hop distance from the information processing apparatus.

5. The information processing apparatus of claim 4, wherein the information transmitter transmits the router information to the mobile terminal having sent the router information request message after the router information is stored in the first information storage unit.

6. The information processing apparatus of claim 5, wherein a router corresponding to the router information converts a protocol of a message to be transmitted to a network using a protocol different from the protocol of the current wireless network.

7. An information processing apparatus for a wireless network, comprising:

an information requester sending a router information request message to a mobile terminal of the wireless network;

an information receiver receiving router information corresponding to the router information request message; and

a second information storage unit storing the received router information.

8. The information processing apparatus of claim 7, wherein the mobile terminal is within 1-hop distance from the information processing apparatus.

9. The information processing apparatus of claim 7, wherein the information requester retransmits the router information request message when the router information is not received within a predetermined period of time.

10. The information processing apparatus of claim 9, wherein the router converts a protocol of a message to be transmitted to a network using a different protocol.

11. An information processing method for a wireless network, comprising:

storing a list containing information of a mobile terminal sending a router information request message regarding the wireless network;

storing router information regarding the wireless network; and

transmitting the stored router information to the motile terminal contained in the list.

12. The information processing method of claim 11, wherein the router information request message is received from a mobile terminal within 1-hop distance from the information processing apparatus.

13. The information processing method of claim 12, wherein the list comprises an address of the mobile terminal sending the router information request message, an ID of the router information request message, and a time when the router information request message is received.

14. The information processing method of claim 13, wherein the storing of the router information comprises:

sending the router information request message to a mobile terminal within 1-hop distance from the information processing apparatus;

retransmitting the router information request message when the router information is not received within a predetermined period of time.

15. The information processing method of claim 14, wherein the router converts a protocol of a message to be transmitted to a network using a different protocol.

16. An information processing method for a wireless network, comprising:

sending a router information request message to a mobile terminal of the wireless network;

receiving router information corresponding to the router information request message; and

storing the received router information.

17. The information processing method of claim 16, wherein the router information request message is transmitted to a mobile terminal within 1-hop distance from the information processing apparatus.

18. The information processing method of claim 17, further comprising retransmitting the router information request message when the router information is not received within a predetermined period of time.

19. The information processing method of claim 18, wherein the router converts a protocol of a message to be transmitted to a network using a different protocol.
