Abstract

In systems and methods for reducing network traffic generated by a plurality of wireless devices operating over a communication network, an indication is received at an access node when a plurality of wireless devices assigned to a subscriber operate simultaneously as active wireless devices over a communication network. A priority list of the active wireless devices arranged according to the highest priority based on operating parameters of the active wireless devices is compiled. One of the active wireless devices is selected as a wireless host device based on the active wireless devices based upon the compiled priority list. Channel state data received from the active wireless devices at the access node is correlated to determine whether the active wireless devices and the wireless host device are in close proximity with each other. A wireless connection is established between the wireless host device and the active wireless devices, that are found to be in close proximity of wireless host device.

First claim

What is claimed is:

1. A method for reducing network traffic generated by a plurality of wireless devices operating over a communication network, the method comprising:
receiving, at an access node, an indication that a plurality of wireless devices assigned to a subscriber are active wireless devices operating simultaneously over the communication network;
compiling a priority list of the active wireless devices arranged according to highest priority based on operating parameters of the active wireless devices;
selecting one of the active wireless devices as a wireless host device based on the active wireless device based upon the compiled priority list;
correlating channel state data received from the active wireless devices at the access node to determine that the active wireless devices and the wireless host device are in close proximity by:
creating and periodically updating a correlation matrix by using an algorithm to correlate the channel state data received from each active wireless device against each other to determine correlation factors; and
deleting from the correlation matrix correlation factors derived based on autocorrelation; and

establishing a wireless connection between the wireless host device and the active wireless devices.

2. The method of claim 1 , wherein receiving, at the access node, the indication further comprises receiving the indication from a control node.

3. The method of claim 1 , further comprising:
receiving at the access node for each active wireless device at least one of channel state data, location data, cell identification data, and Global Positioning System (GPS) data.

4. The method of claim 1 , wherein the active wireless devices in close proximity with the wireless host device have a high correlation factor during a particular period of time.

5. The method of claim 1 , wherein the active wireless devices in close proximity with the wireless host device have a correlation factor within a range of {−1, +1}.

6. The method of claim 1 , wherein establishing the wireless communication further comprises:
disconnecting the active wireless devices connected with the wireless host device from the communication network; and
routing communications from the active wireless devices connected with the wireless host device through the wireless host device to the communication network.

7. The method of claim 1 , wherein compiling a priority list of the active devices further comprises:
compiling the priority list of the active wireless devices arranged upon highest priority based on operating parameters of the active wireless devices based on at least one of hotspot capability, multiple input multiple output (MIMO) capability, and antenna gain.

8. The method of claim 1 , wherein the plurality of wireless devices includes a plurality of active wireless devices and idle wireless devices.

9. The method of claim 1 , wherein selecting the wireless host device further comprises:
selecting the wireless host device is based upon leveraging higher network throughputs and lower network utilization.

10. The method of claim 1 , wherein the plurality of wireless devices have short range communication capabilities including at least one of a wireless LAN, Wi-Fi, and Bluetooth.

11. The method of claim 1 , wherein the plurality of wireless devices comprises at least one of a motor vehicle, a vehicle having communications capability, a personal digital assistant (PDA), a cellular phone, a mobile phone, a smartphone, a computer, a laptop computer, a tablet computer, an electronic device, an electronic gaming device, and a digital camera.

establish a wireless connection between the wireless host device and the active wireless devices in close proximity;
disconnect the active wireless devices connected with the wireless host device from the communication network; and
route communications from the active wireless devices connected with the wireless host through the wireless hotspot device to the communication network.

13. The system of claim 12 , wherein the processing node is further configured to:
create and periodically update a correlation matrix by using an algorithm to correlate the channel state data received from each active wireless device against each other to determine correlation factors; and
delete from the correlation matrix correlation factors derived based on autocorrelation.

14. The system of claim 12 , wherein the processing node is further configured to:
receive at the access node for each active wireless device at least one of channel state data, location data, cell identification data, and Global Positioning System (GPS) data.
