Abstract
The present invention is related to a method, base station (RBS) and computer program for quickly recovering from a detected congestion over the air interface. First the current bitrate at the which the air interface congestion has been detected is stored as a new reference bitrate. Thereafter, the base station (RBS) requests a reduction of the bitrate associated with the air interface. When the congestion condition has subsided the base station (RBS) requests a boost of the bitrate associated with the air interface up to the stored new reference bitrate. When finally the new reference bitrate has been reached, the base station (RBS) requests a linear increase of the bitrate associated with the air interface.
