| 摘 要： | 随着我国第三代移动通信建设的日益临近,多媒体业务需求增长,以传统的以马尔可夫假设为基础的信源模型的单一语音业务正面临挑战.以语音、视频和数据为一体的第三代移动业务被发现不具有马氏假设的特性,而更多表现为自相似特性.因此这里介绍了自相似过程的数学模型,并研究了利用大量具有符合Pareto重尾分布的on/off源叠加产生自相似业务的方法,并且在OPNET网络仿真软件下实现的自相似业务模型.

| Abstract: | With the wide deployment of the third generation mobile communication in our country, the situation of single voice traffic has been changed, and the source model based on Markov theory is facing challenge. The 3G mobile integration service systems of voice, video and data traffic have more characteristic of self - similar than Markov theory. This paper introduces the mathematical model of self - similar. The method for producing self- similar traffic by assembling multi - Pareto distribution on/off sources is researched. Then the self- similar traffic model implemented by OPNET network simulation software is discussed. |
