Abstract
In a method for controlling congestion within a cell of a wireless network providing mobile HTTP adaptive streaming (HAS), a mobile HAS client in the cell delays a request for a next HAS segment of a HAS media stream for a delay time interval in response to a notification of congestion within the cell. The mobile HAS client calculates a reduced bitrate for the next HAS segment, and requests the next HAS segment at the reduced bitrate after expiration of the delay time interval. The reduced bitrate is reduced relative to a bitrate for a previous HAS segment of the HAS media stream.
