Abstract

Exemplary embodiments are directed to devices and methods for supporting a wireless access point for one or more mobile clients. A mobile device may include a first module for supporting access to a network via a first wireless access protocol. The device may further include a second module for supporting a wireless access point for the one or more mobile clients to the network using a second wireless access protocol.

Claims

1. A mobile device, comprising:

a first transceiver for supporting access to a network via a first wireless link using a first wireless access protocol; and

a second transceiver for supporting a wireless access point for one or more mobile clients to the network via a second wireless link using a second wireless access protocol, the one or more mobile clients being unable to use the first wireless access protocol to access the network, the mobile device further configured to alter at least one of support for the first wireless link or the second wireless link upon detecting a change in the mobile device'"'"'s resource capability, the second transceiver being further configured to initiate a handoff of at least one of the one or more mobile clients to another mobile device configured to support a wireless access point responsive to the change in the mobile device'"'"'s resource capability, the change in the mobile device'"'"'s resource capability comprising an available bandwidth on the first wireless link falling below a predetermined threshold.

2. The mobile device of claim 1, the first wireless access protocol comprising a wireless access protocol for a Wireless Wide Area Network (WWAN) and the second wireless access protocol comprising a wireless access protocol for a Wireless Local Area Network (WLAN).

3. The mobile device of claim 1, the first wireless access protocol being different from the second wireless access protocol.

4. The mobile device of claim 1, further comprising a third transceiver for altering the support of the wireless access point in response to a resource related event.

5. The mobile device of claim 1, further comprising a first network interface for supporting access to the network via the first wireless access protocol and a second network interface for supporting the wireless access point for the one or more mobile clients.

6. The mobile device of claim 5, the second network interface including a transceiver function for providing an 802.11 access point for the one or more mobile clients.

7. A mobile device, comprising:

a first wireless transceiver to support a first wireless link to a network using a first wireless access protocol; and

a second wireless transceiver to support a second wireless link with one or more mobile clients using a second wireless access protocol, the mobile device configured to support a wireless access point for the one or more mobile clients to the network by bridging the second wireless link to the first wireless link, the one or more mobile clients being unable to use the first wireless access protocol associated with the first wireless link to access the network, the mobile device further configured to alter at least one of support for the first wireless link or the second wireless link upon detecting a change in the mobile device'"'"'s resource capability, the mobile device being further configured to initiate a handoff of at least one of the one or more mobile clients to another mobile device configured to support a wireless access point responsive to the change in the mobile device'"'"'s resource capability, the change in the mobile device'"'"'s resource capability comprising an available bandwidth on the first wireless link falling below a predetermined threshold.

8. The mobile device of claim 7, the first wireless access protocol configured to support one of Evolution-Data Optimized (EV-DO), Ultra Mobile Broadband (UMB), and Long Term Evolution (LTE).

9. The mobile device of claim 7, the second wireless access protocol comprising IEEE 802.11.

10. The mobile device of claim 7, wherein the mobile device is configured to alter support of the wireless access point in response to a resource related event.

11. The mobile device of claim 10, wherein the resource related event is one or more of the following:

an indication that an energy level is below an energy threshold;

or an indication that a loading on the processing system is above a loading threshold.

12. A method, comprising:

establishing a first wireless link between a network and a mobile node using a first wireless access protocol;

establishing a second wireless link between one or more mobile clients and the mobile node using a second wireless access protocol;

bridging the first wireless link to the second wireless link to provide a wireless access point for the one or more mobile clients to the network, the one or more mobile clients being unable to use the first wireless access protocol associated with the first wireless link to access the network;

altering at least one of support for the first wireless link or the second wireless link upon detecting a change in the mobile device'"'"'s resource capability; and

initiating a handoff of at least one of the one or more mobile clients to another mobile device configured to provide a wireless access point responsive to the change in the mobile device'"'"'s resource capability, the change in the mobile device'"'"'s resource capability comprising an available bandwidth on the first wireless link falling below a predetermined threshold.

13. The method of claim 12, wherein the first wireless access protocol comprises a WWAN protocol.

14. The method of claim 12, wherein the second wireless access protocol comprises a WLAN protocol.

15. The method of claim 12, further comprising modifying support of the wireless access point in response to a resource related event.

16. A non-transitory machine-readable medium comprising instructions executable by one or more processors in a processing system of a mobile node, the instructions comprising code for:

establishing a first wireless link between a network and a mobile node using a first wireless access protocol;

establishing a second wireless link between one or more mobile clients and the mobile node using a second wireless access protocol;

bridging the first wireless link to the second wireless link to provide a wireless access point for the one or more mobile clients to the network, the one or more mobile clients being unable to use the first wireless access protocol associated with the first wireless link to access the network;

altering at least one of support for the first wireless link or the second wireless link upon detecting a change in the mobile device'"'"'s resource capability; and

initiating a handoff of at least one of the one or more mobile clients to another mobile device configured to provide a wireless access point responsive to the change in the mobile device'"'"'s resource capability, the change in the mobile device'"'"'s resource capability comprising an available bandwidth on the first wireless link falling below a predetermined threshold.

17. A device, comprising:

means for establishing a first wireless link between a network and a mobile node using a first wireless access protocol;

means for establishing a second wireless link between one or more mobile clients and the mobile node using a second wireless access protocol;

means for bridging the first wireless link to the second wireless link to provide a wireless access point for the one or more mobile clients to the network, the one or more mobile clients being unable to use the first wireless access protocol associated with the first wireless link to access the network;

means for altering at least one of support for the first wireless link or the second wireless link upon detecting a change in the mobile device'"'"'s resource capability; and

means for initiating a handoff of at least one of the one or more mobile clients to another mobile device configured to provide a wireless access point responsive to the change in the mobile device'"'"'s resource capability, the change in the mobile device'"'"'s resource capability comprising an available bandwidth on the first wireless link falling below a predetermined threshold.
