A method for congestion control in a transport network of a radio access network is provided, wherein the radio access network comprises a control node and two or more radio access nodes, wherein the two or more radio access nodes are coupled to the control node through the transport network. The method comprises receiving, by the control node, a first uplink flow through a first communication link in the transport network from a first of the two or more radio access nodes and receiving, by the control node, a second uplink flow through a second communication link in the transport network from a second of the two or more radio access nodes. If congestion is detected in the transport network for the first uplink flow, triggering, by the control node, either Active Queue Management, AQM, based congestion control at the control node, or local congestion control at the first radio access node for the first uplink flow. If congestion is detected in the transport network for the second uplink flow, triggering, by the control node, either AQM based congestion control at the control node, or local congestion control at the second radio access node for the second uplink flow. The triggering is carried out such that AQM based congestion control is carried out for only one of the first uplink flow or the second uplink flow if congestion is detected for both the first uplink flow and the second uplink flow. |
