Method of controlling traffic flows in a radio communications network, remote node and radio communications network

摘要

A method (100) of controlling traffic flows in a radio communications network, the method comprising steps of: receiving (102) at a remote node a plurality of traffic flows transmitted from a plurality of radio units; buffering (104) the traffic flows in a common buffer of the remote node; and causing (106) a control signal to be sent to a baseband unit when a fill level of the common buffer is predicted to go above a maximum fill level within a pre-set time interval, wherein the control signal is configured to cause an adjustment of a radio resource allocation of one of the plurality of radio units to cause a reduction in a data rate of the traffic flow transmitted from said radio unit.
