基于用户感知的网络覆盖评价新方法研究

Research on New Network Coverage Evaluation Method Based on User Perception

传统的DT/CQT测试覆盖率无法准确地反映与用户分布相关的网络真实情况。文章研究了一种利用用户无线话单(CDT/CDR)海量数据统计覆盖率指标方法。此方法基于用户每次实际呼叫,相对于传统DT/CQT测试更贴近用户感知。在此基础上深入分析此覆盖率指标与话务量关系,通过海量数据分析统计,挖掘深度指标,提出了一系列衡量覆盖率、导频污染的分析方法。在网络现状下,创新性地给出了话务量对覆盖率影响的定量指标,并进一步预测了网络覆盖率指标发展趋势,对覆盖率考核指标的优选进行了研究。在深入研究指标的基础上,江苏公司建立了基于用户感知的网络覆盖评价体系,对深度覆盖、系统优化、网络质量预测起到了关键性的指导作用。

The traditional DT/CQT test coverage rate can not accurately reflect reality associated with the user distribution network. The article studied a kind of using wireless users （CDT/CDR） billed in huge amounts of data statistics coverage index method. This method is based on the user each time the actual call, compared with traditional DT/CQT testing closer to the user perception. On the basis of in-depth analysis of the relationship between coverage index and traffic, statistics, through the analysis of the huge amounts of data excavation depth index, put fbrward a series of measure coverage, pilot pollution analysis method. Under the present situation of network, innovative traffic impact on the coverage of quantitative indicators are given, and forecasts the developing trend of network coverage indicators of coverage optimization of evaluation indices is studied. In index on the basis of in-depth study, Jiangsu company based on user perception of network coverage evaluation system is established, the depth of coverage, system optimization, network quality prediction has played a key role in guiding.
