摘　　要：详细介绍了移动通信网络中的业务带宽调整问题,着重介绍了其中的公平性和开销问题;并介绍和分析了现有的3种带宽调整方案,比较了他们各自的优缺点,提出了一种新的带宽调整方案。该方案采用固定的带宽升降级比率和循环升降级的方法,既保证了带宽升降级时的公平性,又有效地控制了网络开销。计算机仿真结果表明了新的方案具有良好的性能。The rate adaptation issue of rate adaptive services in mobile communication network is introduced, and especially its fairness and overhead problems are discussed in detail in this paper. Three current rate adaptation schemes are also introduced and analyzed and a new scheme is proposed. The new scheme employs fixed rate upgrade/degrade ratios and adjusts the rates of each connection in turn. So during the rate adaptation, it not only ensures the fairness but also limits the network overhead. The computer simulation results show that the new scheme has better performance.
