摘　　要：主述在3G网络中,Iub接口在基于ATM/E1的传输方式下,因为部分E1传输发生中断后,带宽分配无法动态调度,使实际网络资源能力小于规划配置资源需求从而引起瓶颈,导致数据传输过程中出现网络拥塞,使HSDPA产生吞吐率大幅度下降的情况。通过剖析其内在拥塞原因,研究其拥塞控制优化手段,从而提高用户的感受度。Mainly describes the 3G network, Iub interface based ATM/EI transmission, because part of the E1 transmission interruption, bandwidth allocation can not be dynamic scheduling, planning capacity less than the actual network resources causing the bottleneck resource allocation needs, resulting inthe digital tlansmission network congestion, the HSDPA throughput dropped significantly; By analyzing its inherent congestion reasbns to study its congestion control optimization tools to improve the user＇s feelings.
