摘要:: 为了设计高性能GSN系统、做好系统容量规划、提升系统服务性能,以分析3G系统中GSN子系统关键性能测量、数据处理能力、未来容量预期及挖掘性能管理数据为系统业务规划提供依据是文中的主要目的。运用了信令面模型和数据面模型统计方法分析系统的容量和性能,接入模式不同的归一化处理容限边界条件方法来分析数据处理能力以及多元线性回归法预测网络流量。仿真分析和实践应用结果表明GSN系统在多种混合复杂接入模式下,能有效分析网络业务负荷状况、预测流量趋势、帮助问题定位以及优化网络性能

Abstract:: In order to solve the problem of planning network capacity and improving the quality of service for high performance GSN,the main purpose of the paper is analyzing the key performance indicators,data processing capability,prediction of network capacity and performance data mining for providing.The methods used in the paper are the computing method of analysis model for GSN and the method of planning network capacity.By means of analyzing signaling service model and data service model,can plan the capacity of system network and measure the performance management analysis of 3G GSN.In addition,the method of normalization for processing on tolerance-boundary conditions is established to analyze data processing capability and network traffic is predicted with multiple linear regressions.The above methods have been implemented effectively to forecast the trend of network traffic and optimize the performance of network.The practical results show that the above policy models meet the requirement of the performance management for 3G GSN and have been testified in experiment effectively
