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 constructing a self-configuring ad-hoc network, comprising:

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

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;

determining the diverse routes based on types of packets transmitted over the self-configuring ad-hoc network;

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

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

2. The method of claim 1, further comprising:

deciding which node channels to utilize; and

collecting signal strength measurements and routing conditions.

3. The method of claim 1, one of the plurality of nodes is a hot spot node configured to operate on multiple WLAN channels simultaneously.

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

means for transmitting information from a 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;

means for utilizing a second channel at the WLAN node to relay the network traffic to a mobile device or a second WLAN node within the ad-hoc network based on types of packets in the network traffic; and

means for utilizing an initial network topography and routing conditions based on network traffic to account for actual field conditions; and

means for altering the network topography to achieve a desired route and a desired field condition for communication within the ad-hoc network.

5. The system of claim 4, further comprising:

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

6. The system of claim 4, further comprising:

means for allocating network traffic to different nodes; and

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

7. A processor that executes instructions for creating an ad-hoc network, the instructions stored in a memory and embodied by executable code for causing a communication device to implement instructions, the instructions comprising:

transmitting information from a 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;

utilizing a second channel at the WLAN node to relay the network traffic to a mobile device or a second WLAN node within the ad-hoc network based on types of packets in the network traffic; and

utilizing an initial network topography and routing conditions based on network traffic to account for actual field conditions; and

altering the network topography to achieve a desired route and a desired field condition for communication within the ad-hoc network.
