A method and a network node for increased utilization of a transport network link over a transport network of a HSPA system. The method comprises detecting (302) a data packet loss in receiving a data packet flow, and detecting (304) data delay information of data packets as received. The method also comprises determining (306, 308, 310) if the detected data packet loss comprise non-congestive data packet loss, based on the detected data packet loss and the detected data delay information. In addition, the method comprises, when the detected data packet loss comprises non-congestive data packet loss, for a pre-determined time period, omitting to perform (312) a congestion action affecting the data packet flow. By determining whether a data packet loss is non-congestive or not, an unnecessary reduction of the bitrate over the transport network can be omitted. |
