【摘要】：随着移动互联网的快速发展，LTE（Long Term Evolution，3G系统的长期演进技术）作为3GPP长期演进技术目前已取得突破性进展。TD-LTE网络于2013年底正式商用，以其低时延、高速率的特性，将为国内用户提供高速、便捷的移动数据网络服务。TD-LTE网络目前仍处于前期建设和优化部署阶段，根据其网络特性和建设方式，如何做好网络前期规划、保证施工质量、快速优化网络性能是建设精品TD-LTE网络的关键。本文描述了TD-LTE网络的主要特征，包括物理层结构、物理层过程等基础知识，同时也详细介绍TD-LTE的关键技术。本文在结合大学城的场景下，对大学城的TD-LTE网络进行规划，并在此基础上进行网络优化。首先，，介绍了F频段及D频段网络规划原则，并在此原则之上确定了大学城的TD-LTE网络规划方案，利用仿真来完善方案，最终确定了工程施工方案。然后，利用规划方案，对网络进行KPI指标优化，给出了优化前后KPI指标对比情况，并具体阐述了影响覆盖、切换、重建及下载速率等常见问题及优化方案，对实际网络建设和优化都具有较强的参考意义。
[Abstract]:With the rapid development of mobile Internet, LTEL long term Evolution (3G) as a long term evolution technology of 3GPP has made a breakthrough. TD-LTE network was officially commercially available at the end of 2013, with its characteristics of low delay and high speed. TD-LTE network will provide domestic users with high speed and convenient mobile data network service. TD-LTE network is still in the early stage of construction and optimization deployment. According to its network characteristics and construction mode, how to do a good job of network pre-planning to ensure construction quality, Fast optimization of network performance is the key to build TD-LTE network. This paper describes the main features of TD-LTE network, including the physical layer structure, physical layer process and other basic knowledge. At the same time, the key technologies of TD-LTE are also introduced in detail. In this paper, the TD-LTE network of the university town is planned and optimized based on the scenario of the university town. Firstly, the network planning principles of F band and D band are introduced, and the TD-LTE network planning scheme of university town is determined on the basis of this principle. The scheme is perfected by simulation, and the project construction scheme is finally determined. Then, using the planning scheme, the paper optimizes the KPI index of the network, gives the comparison of the KPI index before and after the optimization, and expounds the common problems and optimization scheme, such as influence coverage, handover, reconstruction and download rate, etc. It has a strong reference significance for the actual network construction and optimization.
