【摘要】：据统计2013年度中国移动TD-SCDMA用户数增加到了2.15亿户,其数据业务收入更是高达987亿元人民币。随着人们对高速数据业务需求的进一步增大,TD-SCDMA数据业务网络优化工作就显的尤为重要。TD-SCDMA数据业务网络优化工作也是武汉虹信公司发展的战略重点。本课题主要采用路测和网管中心数据分析相结合的方法对TD-SCDMA数据业务网络优化进行研究。首先在路测过程中,通过实测网络覆盖数据,及时分析现象、定位问题,进而找出网络问题产生的原因并给出优化方案。再通过网管中心的后台数据跟踪,对比分析前期测试数据和优化后的测试数据,将网络数据业务优化问题按无线覆盖问题、干扰问题、无线参数配置问题、传输带宽设置问题、用户端问题归纳聚类,为优化提供决策支持。目前路测与后台网管中心数据分析相结合的方法已经在我公司TD-SCDMA数据业务网络优化工作中推广使用。这种主动式的优化方法在提高用户感知度、降低投诉率等方面的工作效率比传统语音业务优化时有了很大提高,在提升了武汉虹信公司行业内竞争力的同时也为后续4G网络优化工作积累了宝贵的经验。
[Abstract]:According to statistics, the number of TD-SCDMA users in China Mobile increased to 215 million in 2013. Its data business revenue is as high as 98.7 billion yuan. With the further increase of people's demand for high-speed data services. TD-SCDMA data service network optimization work is particularly important. TD-SCDMA data service network optimization work is also the strategic focus of the development of Wuhan Hongxin Company. The network management center data analysis method is combined to study the TD-SCDMA data service network optimization. First, in the road test process. Through the measurement of network coverage data, timely analysis of phenomena, positioning problems, and then find out the causes of network problems and give the optimization scheme, and then through the network management center of the background data tracking. Comparing and analyzing the pre-test data and the optimized test data, the network data service optimization problem is divided into wireless coverage problem, interference problem, wireless parameter configuration problem, transmission bandwidth setting problem. User side problem clustering. To provide decision support for optimization. At present, the method of combination of road test and data analysis of backstage network management center has been popularized and used in the TD-SCDMA data service network optimization work of our company. This kind of active optimization method. The method is improving the perception of the user. Compared with the traditional voice service optimization, the efficiency of reducing the complaint rate has been greatly improved, which not only improves the competitiveness of Wuhan Hongxin Company, but also accumulates valuable experience for the subsequent 4G network optimization.
