资源的高效利用与服务质量保证是多频时分多址（ MF?TDMA）卫星通信系统正常运行的关键技术。通过对典型的周期轮询信道分配算法进行分析，针对该算法实时业务掉线率较高的缺点，提出了差值分配算法。新算法是在周期轮询信道分配算法的基础上，结合业务带宽需求动态变化的特点，将业务带宽申请分为固定部分与差值部分并分别采取不同的分配策略。仿真结果表明，新算法可以有效地降低实时业务的掉线率。

The efficient utilization of resources and QoS guarantee are key technologies in the normal operation of multiple frequency time division multiple access( MF?TDMA) satellite communication system. By analyzing the typical periodic polling channel allocation algorithm,it finds that this algorithm has a high dropping rate to real?time business. Due to high dropping rate of real?time business in using this algorithm,a differential distribution algorithm is proposed.Based on periodic polling channel allocation algorithm, according to the dynamic change of business bandwidth requirements, the new algorithm divides the business bandwidth request into fixed part and difference part by adopting different distribution strategies.Finally,the simulation results show that the new algorithm can effectively bring down the dropping rate of real?time business.
