基于城市热点地区的TD系统网络优化研究

中国移动的3G系统,采用的是中国大唐公司的TD-SCDMA系统,它涉及到与另外两个成熟的3G系统不同的核心技术,比如TDD、智能天线、联合检测、软件无线电、动态信道分配等,因此它的网络优化是没有什么经验可以借鉴的。通过对TD-SCDMA系统网络结构、网络常见问题的分析,给出了城市热点地区的TD系统网络优化方法,最后结合南宁市热点地区的实际案例来解决网络优化方面的实际问题,并提出准确利用TD路测软件,再结合专业分析与现场参数合理配置,达到网络的性能指标最佳状态的行之有效的整改方案。

Research on TD Network System Optimization Based on Urban Hotspots

The TD-SCDMA system of China Datang Corporation is adopted in China mobile 3G system, which involves the core technology different frnm the other two mature 3G systems, such as TDD, the smart antenna, joint detection, software radio, dynamic channel allocation, etc. Hence, there is no reference fi）r network optimization. By analyzing system network configuration and basic network problems, providing optimization methods for TD system network in urban hotspots and combining the practical cases in Nanning urban hotspots to solve the practical problems in urban hotspots, the article proposes the effective rectification program to make correct use of TD route test software in combination of professional analysts and reasonable allocation of on-the- spot parameters, and get the network performance indicators into the best shape.
