HTTP业务是构成3G数据业务的重要部分，因此有必要研究3G网络承载HTTP业务时的性能。介绍了HTTP业务 的基本概念后，提出一种基于网页对象的建模方法，并在OPNET平台上得到实现。最后，根据仿真得到的流量数据，用方差一 时间曲线图和R／S图法分析了模型的自相似特性，验证了模型的正确性。-HTTP operations constitute an important part of 3G data services, 3G networks it is necessary to st

There is a growing interest of wireless operators to migrate their existing 3G networks to different 4G technologies such as Wi MAX and L TE. In this heterogeneous environment of wireless networks and architectures, one of the major concerns is h
