摘要
传统的基于KPI评估体系的路测软件不能满足无线网络优化中用户感知(QoE)的要求,本文以QoE为导向,采用内存-磁盘映射存储机制设计出了一种适合路测软件的数据存储结构,提出了一种后台数据分析模块的设计方案,使用分析管理器为用户提供定制自定义分析项目的接口,使用表达式编辑器为用户提供定制自定义参数、事件和指标的接口。实际测试结果表明,数据库系统的设计很好的满足路测软件对数据存取的要求,后台分析模块的设计使得后台数据分析更加灵活高效,符合QoE评估体系的要求。
Traditional Drive Test Software based on KPI Rating System has been not able to meet the requirement of QoE（Quality of Experience） in wireless network optimization. In this paper, a new type of data storage structure using Memory-Disc Mapping Mecha- nism, which would be appropriate for Drive Test software, is proposed. The design and implementation of the Data Analysis Module is also proposed. The design of Analysis Manager supplied the interface for users to define analysis items and the design of Expression Editor supplied the interface for users to edit concerned parameters, events and indicators. Practical testing results indicate that the design of the Data Storage Module is well-adapted to the Drive Test Software and the design of the Data Analysis Module makes the Data Analysis more flexible and reliable, meeting the demands of QoE Evaluation System.
