Abstract

A sender in a wireless network may adjust the encoding bit rate of the transmitted content and/or the transmission bit rate of the content based on the predicted future channel throughput at a predicted future geographical position of a client mobile device, such as a cellular telephone. By appropriately adjusting the bit rate prior to the client mobile device experiencing the predicted low throughput, the likelihood of continuous content consumption by the client mobile device, even while experiencing the predicted low throughput conditions, may be increased. The prediction may be performed at the network side and/or at the client mobile device side.

receiving an indication of at least one of a location and a direction of the client mobile device,

wherein the determining comprises determining that the client mobile device will enter a network outage region based on the received indication of the at least one of the location and the direction.

9. The method of claim 8, wherein the determining further comprises determining that the client mobile device will enter a network outage region based on a comparison of the received indication of the at least one of the location and the direction, and stored data indicating a plurality of locations of network outage regions.

10. The method of claim 9, further comprising:

receiving from the client mobile device an indication of a quality of a wireless signal experienced by the client mobile device; and

associating the indication of the quality of the wireless signal with the indication of the at least one of the location and the direction of the client mobile device.

11. The method of claim 1, further comprising:

receiving coverage data associated with the client mobile device,

wherein the determining comprises determining that the client mobile device will enter a network outage region based on the received coverage data.

12. A computer-readable medium storing computer-executable instructions for performing a method, the method comprising:
