Abstract :
This paper proposes and evaluates power-based congestion control mechanisms in the WCDMA downlink air interface based on the functionalities of the call admission control (CAC), conversational service class rate adaptation (RA) via AMR codec and load control (LC) algorithms. It is verified by means of dynamic system level simulations that the congestion control technique is capable of guaranteeing the users´ QoS requirements even for high offered loads.
