摘　　要：中国移动根据实验网的测试情况和传送网技术发展体制,最终选择了PTN L3 VPN作为TD-LTE基站回传的传输方案。本文在分析了TD-LTE对传送网新挑战的基础上,重点针对如何提高传送网灵活性和高带宽,提出了现阶段面向TD-LTE的城域传送网的承载解决方案,分析了可能遇到的困难,并给出一些建议。CMCC finally choose the PTN L3 VPN as TD-LTE backhaul solution which based on test results of test network and transport network technology development system. The paper analyses the new challenges of the transport network faced to TD-LTE, proposes MAN transport network carrying strategy which focused on how to improve the flexibility and high bandwidth, analysises possible difficulties, and proposes rationalization proposals also.
