(1) Characterization and Modeling of Multimedia TrafficWe have observed the 1/f property in the sequence of MPEG 2 variable bite rate compressed frames of a real video by the spectral analysis. We have also developed a method to generate an artificial long memory process from the sequence of the numbers of customers in an M/G/* queueing system.(2) Evaluation of Call Loss Probabilities in Cellular Mobile NetworksWe have evaluated the loss probability of new calls and the forced termination probability of hand-off calls for cellular mobile networks with non-uniform traffic conditions by numerical calculation of Markov models and simulation. Those probabilities have been compared between the current frequency division multiple access (FDMA) and the future code division multiple access (CDMA) schemes.(3) Analysis of Probability Models for Complex Communication Networks(a) We have analyzed a queueing system in which the input consists of a special semi-Markov process representing MPEG frame sequences and a Poisson process representing the interfering traffic, and evaluated the frame transmission delays based on the parameter values of real video data.(b) We have studied the throughput and delay performance of the IEEE 1394 serial interface, and compared with CSMA/CD of Ethernet by using a simulation software package QPNET.

(1)多媒体传输的特征与建模通过频谱分析，观察到实际视频的MPEG2变比特率压缩帧序列具有1/f特性。(2)蜂窝移动网络中呼叫丢失率的评估我们通过马尔可夫模型的数值计算和仿真，对非均匀业务条件下蜂窝移动网络的新呼叫丢失率和切换强制终止概率进行了评估。(3)复杂通信网络概率模型分析(A)我们分析了一个输入由一个特殊的半马尔可夫过程代表的MPEG帧序列和一个代表干扰业务的泊松过程组成的排队系统，并根据实际视频数据的参数值评估了帧传输时延。(B)我们研究了IEEE 1394串口的吞吐量和时延性能，并与以太网的CSMA/CD进行了比较。
