基于信令分析的TD-SCDMA速率优化方案及实践

Solution and practice for speed optimization of TD-SCDMA networks based on signaling analysis

数据业务的网络优化相较于话音业务更加复杂,仅从网管统计和日常路测无法全面分析业务的服务质量与影响业务服务质量的因素,需要进一步考虑引入信令分析系统等手段提升分析和优化能力。通过Gb信令数据和无线侧数据的关联分析,可以从小区中用户上网行为去还原网络中的数据业务速率低的问题,从而制定相应的解决方案,提升数据业务上网速率和用户满意度。

Compared to voice services, the network optimization of data services is more complex. For data service,it is not enough to get a comprehensive analysis of the status and the factors for service quality usingnetwork statistics and daily driver tests. Therefore, other tools like signaling analysis systems shouldbe used to improve the ability for analyzing and optimizing mobile networks. An analysis method isintroduced, which can help restoring low-speed problems on data services from users’ online behavior.It is achieved through the association analysis of Gb signaling data and radio network data. Based onthis method, the solution for low-speed problem may be developed. Then the service speed and usersatisfaction can be improved.
