在许多文献中,无线网络的呼叫到达间隔和信道占用时间都是假定为指数分布的.本文中,我们假定这两类呼叫到达过程为 Markov 过程,信道占用时间服从位相型分布.利用矩阵分析法,我们得到了系统的排队指标.最后我们给出数值例子说明了不同呼叫到达流对性能指标的影响.

@@@@In many bibliographies, the exponential inter-arrival time and channel holding time are always considered for the handoff and new calls in wireless networks. In this paper, we extend this assumption to the Markov arrival process (MAP) and phase-type (PH) distribution of channel holding times. By applying the matrix analytic techniques, we obtain some performance measures of the system. Finally, we give numerical results to indicate the input of different calls arrival rate on performance measures.
