Downlink Congestion Control for TD-SCDMA Trunking System

In TD-SCDMA truiiking system, imperfect power control and user mobility are disadvantages for the capacity and performance of the system. In order to meet the requested Quality of Service (QoS) of group users, in this paper, we introduce a congestion control mechanism in downlink for TD-SCDMA trunking system. The mechanism is based on Adaptive Multi-Rate (AMR) mode selection and interrupt connections of users, analyzed in detail and verified by using MATLAB to structure a dynamic system level simulation platform. The simulation results reveal that system performance can be significantly improved.
