摘要：

相比传统网络，网络结构对TD-LTE网络质量的影响更大，如果仅在原有TD-SCDMA站点基础上进行简单升级，必将继承其原有的结构和质量问题。针对直接升级时遇到的共天馈协同优化问题，提出了一种协同网络优化方法，利用工参信息、MR（测量报告）、扫频和路测等数据，从网络结构、覆盖和干扰等维度解决了TD-SCDMA和TD-LTE的网络问题；然后，针对这些问题，运用规划与优化工具输出了协同优化方案，并在现网进行了验证；最后，通过对实施效果进行评估，总结了TD-SCDMA与TD-LTE协同优化调整策略。

Abstract:

Compared to traditional network，the network structure has a greater impact on the quality of TD-LTE network.If only upgrade directly in the original site based on TD-SCDMA，the original structure and quality issues would be inherited.On the basis of the problems encountered in the shared antenna collaborative optimization，a collaborative network optimization method was presented.Network problems of TD-SCDMA and TD-LTE were solved from the dimensions of network structure，coverage and interference by using project parameters，measurement report，frequency sweep test，driving test and other data.After that，by using network planning and optimization tools，collaborative optimization scheme was outputted and verified in the existing network to solve these problems.Finally，TD-SCDMA and TD-LTE collaborative optimization adjustment strategy was summed up by evaluating implementation effects.

Key words: TD-LTE, TD-SCDMA, shared antenna, network optimization, collaborative optimization
