Abstract

A wireless device is communicated with using a first throughput. A predicted location for the wireless device is determined. Based on the predicted location, a predicted maximum throughput at the predicted location is determined. Based on the predicted maximum throughput, a second throughput is determined. The wireless device is communicated with using the second throughput.

Claims

1. A method of operating a communication system, comprising:

communicating, using a first throughput, with a wireless device;

determining a predicted location for the wireless device;

based on the predicted location, determining a predicted throughput at the predicted location;

based on the predicted throughput, determining a second throughput; and

,

communicating, using the second throughput, with the wireless device.

2. The method of claim 1, wherein, if the predicted throughput is less than a minimum throughput, the second throughput is no greater than the minimum throughput.

3. The method of claim 1, wherein, if the predicted throughput is greater than a maximum throughput, the second throughput is greater than the maximum throughput.

4. The method of claim 1, wherein the predicted throughput is based on a predicted modulation and coding scheme associated with the predicted location.

5. The method of claim 1, wherein the predicted throughput is based on a predicted signal quality indicator associated with the predicted location.

6. The method of claim 1, wherein the predicted throughput is based on a predicted network resource availability associated with the predicted location.

7. The method of claim 5, wherein the predicted location is associated with a base station and the predicted network resource availability is based on an air-interface resource availability associated with the base station.

8. The method of claim 5, wherein the predicted location is associated with a network and the predicted network resource availability is based on network resource availability associated with the network.

9. A method of operating a communication system, comprising:

determining a predicted location of a wireless device;

determining, based on the predicted location, a predicted throughput from a content server to the wireless device;

determining that the predicted throughput satisfies a criteria; and

,

based on the predicted throughput satisfying the criteria, determining a throughput for the content server to send data to the wireless device.

10. The method of claim 9, wherein the criteria comprises the predicted throughput exceeding a minimum bitrate associated with content that content server is providing to the wireless device.

11. The method of claim 9, wherein the criteria comprises the predicted throughput exceeding a maximum bitrate associated with content that content server is providing to the wireless device.

12. The method of claim 9, wherein the predicted throughput is based on a predicted modulation and coding scheme associated with the predicted location.

13. The method of claim 9, wherein the predicted throughput is based on a predicted signal quality indicator associated with the predicted location.

14. The method of claim 13, wherein the predicted location is associated with a base station and the predicted throughput is based on an air-interface resource availability associated with the base station.

15. The method of claim 13, wherein the predicted location is associated with a network and the predicted throughput is based on network resource availability associated with the network.

16. A method of operating a communication system, comprising:

determining a first location at a first time for a wireless device;

determining a second location at a second time for the wireless device;

based on the first location, the second location, the first time, and the second time, determining a predicted location at a third time for the wireless device;

based on the predicted location and the third time, determine a predicted throughput; and

,

based on the predicted throughput, send an indicator of desired throughput to a content server.

17. The method of claim 16, wherein based on the predicted throughput being less than a minimum bitrate associated with content that the content server is providing, the desired throughput is less than a current throughput to the wireless device.

18. The method of claim 16, wherein based on the predicted throughput exceeding a maximum bitrate associated with content that the content server is providing, the desired throughput is more than a current throughput to the wireless device.

19. The method of claim 16, wherein the predicted location would result in a different network device providing network resources to the wireless device than the second location.

20. The method of claim 16, wherein the predicted location is associated with a base station and the predicted throughput is based on an air-interface resource availability associated with the base station.
