摘　　要：通过重构概率空间,建立了一种在有限缓冲区条件下的综合业务服务轮询多址通信接入系统的离散型排队G/G/1(G)/L/FCFS模型,并利用嵌入马尔可夫链理论和概率母函数,对系统的丢失率进行了详细的数学分析.计算机仿真的结果表明了模拟与理论的一致性.A new polling queuing model G/G/1 （G） /L/FCFS is set up by rebuilt probability space, for the support of integrated service in discrete time in Polling Multi - Access Communications System with limited buffers. According to the imbedded Markov chain theory and the generating function, a mathematical analysis on the packet loss rate of the system is explicitly made, and the results of computer simulation show their concordance with the theoretical analysis.
