【摘要】：我国幅员辽阔,为了满足覆盖的要求就需要建设大规模的移动通信网络,因此需要运营商进行巨大的投入才能实现。随着我国移动通信网络建设与技术的不断发展,我国的移动通信网络进入了2G、3G、4G网络共存的状态。目前我国三大通信运营商的移动2G与3G网络建设都已有较大规模,中国移动已在20多个城市开始TD-LTE网络商用,中国电信和中国联通也已开始TD-LTE网络建设。随着无线网络规模的不断扩大,无线网络优化成为了保证和提升网络质量的关键工作。本文从GSM和WCDMA网络的日常优化工作及TD-LTE网络的工程优化工作出发,结合GSM、WCDMA和TD-LTE系统的理论知识和网络优化方法对实际工作中遇到的问题进行研究与分析。首先对日常优化工作中通过话务统计、测试和申告发现的问题进行分析,进而采用具体的方法对进行网络优化；然后对工程优化中测试发现的问题进行分析,找出其产生的原因并做出调整。通过各种的优化手段提升网络质量与性能,为通信业务的发展奠定坚实的基础。
[Abstract]:Our country has a vast territory, in order to meet the requirements of coverage, we need to build a large-scale mobile communication network, so it needs the operators to carry out a huge investment in order to achieve. With the continuous development of mobile communication network construction and technology in China, the mobile communication network in China has entered the coexistence of 2G / 3G / L 4G network. At present, the mobile 2G and 3G network construction of the three major communication operators in China have been on a large scale. China Mobile has started TD-LTE network commercial in more than 20 cities, and China Telecom and China Unicom have also begun to build TD-LTE network. With the continuous expansion of wireless network scale, wireless network optimization has become the key to ensure and improve network quality. Based on the daily optimization work of GSM and WCDMA networks and the engineering optimization work of TD-LTE network, this paper studies and analyzes the problems encountered in practical work by combining the theoretical knowledge of GSMN WCDMA and TD-LTE systems and network optimization methods. First of all, through the daily optimization work through traffic statistics, testing and declaration found problems are analyzed, and then the specific method is used to optimize the network, and then the problems found in the engineering optimization test are analyzed. Identify the causes and make adjustments. To improve the network quality and performance through various optimization methods, lay a solid foundation for the development of communication services.
