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

determining a predicted location for the wireless device;

determining a predicted throughput at the predicted location, wherein the predicted throughput is determined based on the predicted location, a predicted backhaul throughput, a predicted access services network gateway throughput, a predicted carrier to interference and noise ratio (CINR) that the wireless device will be using at the predicted location, and a predicted modulation and coding scheme (MCS) that the wireless device will be using at the predicted location;

based on the predicted throughput, increasing or decreasing the first throughput to a second throughput at which the content is communicated before the wireless device reaches the predicted location; and

communicating the content, using the second throughput, with the wireless device, wherein when the predicted throughput is greater than a maximum throughput required at the predicted location, the second throughput is greater than the maximum throughput.

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

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

4. The method of claim 3, 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.

5. The method of claim 3, 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.

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

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

determining a predicted location of a wireless device;

determining a predicted throughput from a content server to the wireless device, wherein the predicted throughput is determined based on the predicted location, a predicted backhaul throughput, a predicted access services network gateway throughput, a predicted carrier to interference and noise ratio (CINR) that the wireless device will be using at the predicted location, and a predicted modulation and coding scheme (MCS) that the wireless device will be using at the predicted location;

determining that the predicted throughput is one of above a maximum threshold or below a minimum threshold;

based on the predicted throughput being one of above the maximum threshold or below the minimum threshold, determining a desired throughput for the content server to send data to the wireless device before the wireless device reaches the predicted location; and

sending data to the wireless device from the content server at the desired throughput, wherein when the predicted throughput is greater than a maximum throughput required at the predicted location, the desired throughput is greater than the maximum throughput.

8. The method of claim 7, wherein the minimum threshold is a minimum bitrate associated with content that content server is providing to the wireless device.

9. The method of claim 7, wherein the maximum threshold is a maximum bitrate associated with content that content server is providing to the wireless device.

10. The method of claim 7, wherein the predicted throughput is based on a predicted signal quality indicator associated with the predicted location.

11. The method of claim 10, 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.

12. The method of claim 10, wherein the predicted location is associated with a network and the predicted throughput is based on network resource availability associated with the network.

13. 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;

determining a predicted throughput at a computer system of the communication system, wherein the computer system comprises a processing system and wherein the computer system determines the predicted throughput based on the predicted location at the third time, a predicted backhaul throughput, a predicted access services network gateway throughput, a predicted carrier to interference and noise ratio (CINR) that the wireless device will be using at the predicted location, and a predicted modulation and coding scheme (MCS) that the wireless device will be using at the predicted location; and

,

based on the predicted throughput, sending an indicator of desired throughput before the wireless device reaches the predicted location from the computer system to a content server, wherein when the predicted throughput is greater than a maximum throughput required at the predicted location, the desired throughput is greater than the maximum throughput.

14. The method of claim 13, 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.

15. The method of claim 13, 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.

16. The method of claim 13, wherein the predicted location would result in a different network device providing network resources to the wireless device than the second location.

17. 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.
