TD-LTE与FDDLTE混合组网策略及参数优化方法

TD-LTE and FDD LTE hybrid network strategy and parameter optimization method

在TD-LTE商业运营半年后,工业和信息化部向部分运营商颁发FDD LTE牌照,FDD LTE商用网络建立一旦开始,必然要和现有的TD-LTE网络进行混合组网,混合组网就必然会涉及两张网络之间的互操作,如何合理利用两张网络各自的优势来提供更好的用户感知,这对两张网络之间的互操作的参数配置有了较高的要求。互操作涉及的参数众多,参数的设置是否合理对网络质量影响很大。通过对TD-LTE现网和FDD LTE实验网的策略及互操作过程进行探究,分析了一些关键的混合组网参数和配置对网络质量的影响,并提出了相关的优化建议。

After the TD-LTE commercial operation has been on for half a year, the Ministry of Industry and Information Technology issued FDD LTE plate to some operators. Actually, once the FDD LTE commercial network is launched, it must be combined with existing TD-LTE network for hybrid networking, which will surely be involved in interoperation between two different networks. The reasonable use of advantages of two networks can provide a better user perception, but it also puts higher requirements on the parameter configuration of interoperation between these two networks. Considering the large amount of parameters involved in interoperation, a reasonable parameter configuration will have a huge impact on network quality. By probing into the strategies and interoperation process of TD-LTE present network and FDD LTE experimental network, an analysis was made on the impact of some key hybrid networking parameters and configurations on network quality, and relevant suggestions were offered for optimization.
