WCDMA Network Data Service Optimizationg Research In Zhaoqing And Applicationg System Design

With five years of development of China Unicom WCDMA network in Zhaoqing City,the number of user increases gradually, the network continues to expand, the network structure becomes more complex too. At the same time the network load increases stealily, bottlenecks appears in network resource visiting correspondingly.As a result, network performance fluctuates even worsen, such as the wireless connection rate decreases, performance of data services is degraded.How to find a solutions for these issues, so as to improve the transmission rate of the network in practical uses, and to improve the user experience on the Internet, to enhance indicators of the data services performance in WCDMA network accurately and quickly,is the research purpose of this dissertation.The principle and data technical characteristics of WCDMA networks are described and analyzed in this dissertation,and working process of WCDMA network data traffic analysis is further studied, also the main factors affecting the WCDMA network data traffic rate is pointed out.According to the actual situation of performance degradation in Zhaoqing WCDMA network data services, and by OMC statistical data analysis with the access performance, neighbor optimization and network capacity, the author found the major factors which caused network data services rate is low, including the success rate of RRC and RAB establishment is low,other four categories of resources,such as the air interface and BTS and transmission capacity and RNC does not match each other. By using signal analysis, NASTAR analysis and statistical analysis tools and other methods,we adjust the parameters for the WCDMA network and add the adjacent cells and expand network, in order to solve the problem of declining rates of network traffic. In this special optimization process, aimed at factors that impact WCDMA network data service rate in Zhaoqing city, this dissertation gives an effective solution scheme to the problem, and according to this scheme a data optimization applications system is designed.Finally we get a good effect in practical uses.By using this scheme and comparing system optimization of the network before and after,the scheme and the system prove effective in improving the network data service rate. The system is used by system engineers in their daily network optimization,and quantity of work is greatly reduced in data extraction, filtering, analysis, their work efficiency is improved greatly. The scheme is applied to optimized in actual WCDMA network and achieves better results in Zhaoqing region.
