                    业务源模型的建立可更好地研究无线移动通信网络的性能,并进行网络规划及系统性能评估。本文以UMTS网络的单用户业务为参考模型,分析其业务特征;以HTTP分组为研究对象,根据其主要行为特性建立业务源模型;针对无线移动应用环境中数据业务,提出了一种适用于3G网络规划的容量估计方法,并通过实例验证业务源模型易实现性及容量估计方法的易解析特性。采用有限状态机来描述业务模型的实现,对无线资源管理和流量控制具有一定的参考价值。
                
                Packet service models are important to the research on the performance of mobile communication systems, network layout and system evaluation. This paper analyzes the characteristics of the UMTS system with its singleuser service as a reference model .A wireless packet service model is built based on the behavior features of HTTP packet flows. We put forward a capacity dimensioning method for the network planning of 3G systems serving the data services in mobile wireless environments.It is indicated by an instance that the method can easily be implemented and numerically analyzed. The service model is described with finite state machines. It is conducive to wireless resource management and flow control.
