Abstract :
TD-SCDMA is a self-interference system, in which congestion control plays a critical role in controlling the load of cells and stabilizing the system itself. On the basis of the common congestion control methods for TD-SCDMA system, this paper proposes an improved congestion control method. That is, to reduce the transmission rate progressively while estimating the load volume to be reduced. By measures like reducing the transmission rate progressively, re-allocating the code channels and forcing a handover, the improved method can increase the utilization rate of the resources while controlling the load of the system effectively.
