With the large scale deployment of 4G networks is getting closer

networking and optimization method of TD-LTE is now of priorities in current TD-LTE network maintenance and optimization. Especially

the different schemes of TD-LTE construction have a significant impact on TD-SCDMA network

therefore

according to the advantages and disadvantages of the different construction schemes

particularly the schemes of upgrading from existing TD-SCDMA sites to TD-LTE sites

this article proposed a collaborative optimization method which is in favor of the dual-network quality improvement of TDSCDMA and TD-LTE

and which will also provide an important reference of the subsequent large-scale TD-LTE deployment and optimization. The study and practice of the network of Wuxi

Jiangsu have achieved the purpose of collaborative optimization.
