Abstract

In one or more embodiments, a mobile device can determine its speed and can utilize a wireless network based on its determined speed. In one example, the mobile device can be within a communications range of a wireless access point that implements a wireless local area network and can utilize a mobile telephone network for data communications rather than the wireless local area network when the mobile device is traveling at or above a certain speed. In another example, the mobile device can receive a signal from the wireless access point and, based on the signal and the speed of the mobile device, the mobile device can utilize the wireless access point at or above the certain speed. For instance, the signal can include a beacon indicating that the wireless access point can be utilized for data communications when the mobile device is traveling at or above a certain speed.

First claim

What is claimed is:

1. A method, comprising:
receiving a beacon signal from a wireless access point at a mobile device;
determining, based on the beacon signal and a size of a buffer of the mobile device, a speed threshold associated with the wireless access point;
determining, at the mobile device, a speed of the mobile device relative to the wireless access point;
performing a comparison of the speed to the speed threshold;
based on the comparison indicating that the speed satisfies the speed threshold, transmitting data from the mobile device to the wireless access point; and
based on the comparison indicating that the speed does not satisfy the speed threshold, transmitting the data from the mobile device to a mobile communication network node of a mobile communication network.

2. The method of claim 1 , wherein the speed satisfies the speed threshold when the speed is less than the speed threshold.

3. The method of claim 1 , wherein the speed satisfies the speed threshold when the speed is greater than the speed threshold.

4. The method of claim 1 , wherein the beacon signal further includes speed information that indicates a speed of the wireless access point or a velocity of the wireless access point.

5. The method of claim 1 , wherein the beacon signal includes a beacon frame that includes speed information associated with the wireless access point.

6. The method of claim 1 , wherein the beacon signal includes an Institute of Electrical and Electronics Engineers 802.11 beacon.

7. The method of claim 1 , wherein the data is transmitted to the wireless access point after receipt of multiple beacon signals from the wireless access point.

8. A mobile device comprising:
a processor;
a first wireless network interface coupled to the processor and configured to communicate to a mobile communications network; and
a second wireless network interface coupled to the processor and configured to communicate with a wireless access point;
wherein the processor executes instructions to perform operations including:
receiving a beacon signal from the wireless access point via the second wireless network interface;
determining, based on the beacon signal and a size of a buffer of the mobile device, a speed threshold associated with the wireless access point;
determining a speed of the mobile device relative to the wireless access point;
performing a comparison of the speed to the speed threshold;
based on the comparison indicating that the speed satisfies the speed threshold, transmitting data to the wireless access point via the second wireless network interface; and
based on the comparison indicating that the speed does not satisfy the speed threshold, transmitting the data to a mobile communication network node of the mobile communication network via the first wireless network interface.

9. The mobile device of claim 8 , wherein the speed threshold corresponds to a speed at which the mobile device is capable of transmitting buffer data in the buffer before leaving a coverage area of the wireless access point.

10. The mobile device of claim 9 , wherein the buffer data corresponds to the size of the buffer.

11. The mobile device of claim 8 , further comprising receiving second data from the wireless access point via the second wireless network interface in response to transmitting the data to the wireless access point.

12. The mobile device of claim 8 , wherein the data is transmitted to the wireless access point after receipt of multiple beacon signals from the wireless access point.

13. The mobile device of claim 8 , further comprising a position device coupled to the processor to provide information associated with the mobile device to the processor to enable determination of the speed.

14. The mobile device of claim 8 , wherein the processor determines the speed by receipt of speed data from the mobile communications network.

15. A computer-readable storage device of a mobile device comprising instructions executable by a processor to perform operations including:
receiving a beacon signal from a wireless access point;
determining, based on the beacon signal and a size of a buffer of the mobile device, a speed threshold associated with the wireless access point;
determining a speed of the mobile device relative to the wireless access point;
performing a comparison of the speed to the speed threshold;
based on the comparison indicating that the speed satisfies the speed threshold, transmitting data to the wireless access point; and
based on the comparison indicating that the speed does not satisfy the speed threshold, transmitting the data from the mobile device to a mobile communication network node of a mobile communication network.

16. The computer-readable storage device of claim 15 , wherein the data is transmitted to the wireless access point after receipt of multiple beacon signals from the wireless access point.

17. The computer-readable storage device of claim 15 , wherein the beacon signal includes a velocity of the wireless access point.

18. The computer-readable storage device of claim 15 , wherein the beacon signal includes an Institute of Electrical and Electronics Engineers 802.11 beacon.

19. The computer-readable storage device of claim 15 , wherein the beacon signal further includes speed information that indicates a speed of the wireless access point or a velocity of the wireless access point.

20. The computer-readable storage device of claim 15 , wherein the speed satisfies the speed threshold when the speed is less than the speed threshold.
