Zusammenfassung:The paper specifies congestion resolution (action) and recovery (reaction) procedures within a load control (LC) functionality in the WCDMA downlink air interface. By means of dynamic system level simulations, it is verified that, in soft overload situations, it is advantageous to give lower priority to those radio links that have worse channel quality, so that the system can return to its stable state in a gradual and controlled manner.
