摘要：A Radio Network Controller, an RNC (105), for an HSPA enabled cellular access system. The RNC is arranged to be connected to a Radio Base Station (110) by a Transport Network (120) through which the RNC (105) sends and receives traffic to and from UEs (115). The RNC (105) comprises a function (210) for Radio Link Control, RLC, for the UEs, and is arranged to detect congestion in the Transport Network (120) to or from each UE. The RNC (105) is arranged to, when detecting congestion in the Transport Network (120) to or from a UE (115), use its RLC function (210) to discard an RLC Service Data Unit, SDU, in a receive buffer, the receive buffer being in the UE (115) if the congestion is in the direction to the UE (115) and in the RNC (105) if the congestion is in the direction from the UE (115).
