Abstract

Embodiments describe registration in a wireless communication system. A method includes wirelessly transmitting over a WWAN a first registration message from a mobile device, wirelessly transmitting through the WWAN a second registration message to a WLAN access point and receiving at the mobile device access through the WLAN access point. According to another embodiment is a method for constructing a self-configuring ad-hoc network. The method can include receiving a GPS coordinate from a WWAN channel node at a management system and creating an initial topography based at least in part on the GPS coordinate to achieve a network connectivity with diverse routes between a plurality of nodes.

Claims

1. A method for registration in a wireless communication system, comprising:

wirelessly transmitting over a WWAN a first registration message from a mobile device;

wirelessly transmitting through the WWAN a second registration message to a WLAN access point; and

receiving at the mobile device access through the WLAN access point.

2. The method of claim 1, transmitting through the WWAN a second registration message, further comprising:

transmitting the second registration message to the WLAN access point.

3. The method of claim 1, transmitting through the WWAN a second registration message, further comprising:

transmitting the second registration message through the WWAN to another mobile device; and

transmitting a third registration message based on the second registration message from the mobile device to the WLAN access point.

4. The method of claim 3, the third registration message is transmitted through an air interface.

5. The method of claim 1, the first registration message comprising an encryption key.

6. A method for constructing a self-configuring ad-hoc network, comprising:

receiving a GPS coordinate from a WWAN channel node at a management system; and

creating an initial topography based at least in part on the GPS coordinate to achieve a network connectivity with diverse routes between a plurality of nodes.

7. The method of claim 6, further comprising:

deciding which node channels to utilize; and

collecting signal strength measurements and routing conditions.

8. The method of claim 6, further comprising:

utilizing the initial topography and routing conditions to account for the actual field conditions; and

altering the topography to achieve a desired route and a desired field condition.

9. The method of claim 6, one of the plurality of nodes is a hot spot node configured to operate on multiple WLAN channels simultaneously.

10. A system for creating an ad-hoc network comprising:

means for accessing a terminal in a WLAN functionality mode;

means for transmitting information from the terminal to at least a second terminal having a dual mode functionality;

means for utilizing a first channel at a WLAN node to pick up network traffic; and

means for utilizing a second channel at the WLAN node to relay the network traffic to a mobile device or a second WLAN node.

11. The system of claim 10, further comprising:

means for routing the traffic through an OSPF type of protocol.

12. The system of claim 10, further comprising:

means for allocating network traffic to different nodes; and

means for deciding a route decision through a communication between WLAN nodes.

13. A computer-readable medium having stored thereon computer-executable instructions for:

sending a first registration message including an encryption key over a WWAN;

communicating a second registration message to a WLAN access point; and

receiving an authorization to communicate through the WLAN access point.

14. The computer-readable medium of claim 13, further comprising instructions for:

communicating the second registration message to the WLAN access point.

15. The computer-readable medium of claim 13, further comprising instructions for:

communicating the second registration message through the WWAN to a mobile device; and

transmitting a third registration message to the WLAN access point.

16. The computer-readable medium of claim 15, the third registration message is based on the second registration message.

17. The computer-readable medium 15, the third registration message is transmitted through an air interface.

18. A processor that executes instructions for creating an ad-hoc network, comprising:

accessing a terminal in a WLAN functionality mode;

transmitting information from the terminal to at least a second terminal having a dual mode functionality;

utilizing a first channel at a WLAN node to pick up network traffic; and

utilizing a second channel at the WLAN node to relay the network traffic to a mobile device or a second WLAN node.
