A method is provided for congestion control in a network node (114; 510; 700; 900) of a communication network (701). The network node handles a plurality of data connections (DC1−N; RAB1−N) for conveying data between a first side and a second side of the communication network. The congestion control involves associating the data connections with respective target weights (wk; k=1−N) for Quality-of-Service (QoS) bit-rate differentiation. The method comprises the following steps, performed in the network node. Experienced bit-rates (rk=1−N) are obtained (620) for the data connections (DC1−N; RAB 1−N). For each data connection (DCi; RAB i), a time integrated difference is determined (632) between the data connection's targeted bit-rate according to its target weight (wi), and its experienced bit-rate (ri). Then, for each data connection, an adjusted weight (w′i) for QoS bit-rate differentiation is calculated (634) based on the determined time integrated difference and the target weight (wi). The adjusted weights (w′k; k=1−N) are used for the congestion control of the data connections. |
