The invention refers to a method for congestion control of IuR resources in an eHSPA or flat architecture mobile communications network in a situation of soft handover, the network having a transport network, in which:
- a User Equipment (10) sends uplink data packets to a serving eNode B (20) and to a number of non-serving eNode Bs (20'),
- from each non-serving eNode B's said uplink data packets are decoded and transmitted in uplink through the transport network (30) over an IuR interface, and then transmitted together with the downlink data to the serving eNode (20);
wherein the method comprises:
- detecting, by the serving eNode B, whether there is congestion in any of the IuR interfaces and where the congestion is located;
- sending a congestion notification to one or more of the non-serving eNode B's (20'), depending on which IuR interface/s the congestion as been detected;
- stop decoding the uplink user plane data packets in one or more of the non-serving eNode B's, maintaining active the decoding of the E-DPCCH. The invention is also related to a network entity comprising means for carrying out the above method. |
