摘　　要：随着数据业务的高速增长,运营商逐渐把业务发展的重心从话音业务转移到数据业务上来。为保证用户的良好感知度,无线通信技术必须快速地向4G时代演进。介绍了TD-LTE无线网络架构,说明了TD-LTE基站的平滑升级主要是在原有TD-SCDMA基站的基础上,从BBU、RRU、天线等设备上到TDS/TDL双模基站的演进,最后通过具体的案例说明了升级方案的可行性。With the rapid growth of data services, operators gradually transfer the focus of the business development from voice service to data seice. In order to ensure the quality of users perception, wireless communication technology must quickly evolve to 4G era. Firstly, TD-LTE wireless network structure is introduced, secondly the smooth upgrade of TD-LTE base station is explained, which is mainly an evolution from BBU, RRU, antenna and other equipments to the TDS/TDL dual-mode base station based on the original TD-SCDMA base stations, finally the feasibility of upgrade solution is illustrated by specific cases.
