摘　　要：针对LTE时期原有乡镇农村本地传输接入层不能满足业务快速发展的现状,研究了不同区域业务发展特点,提出了一种乡镇农村本地传输接入层改造策略。该策略把现有本地接入层再细分为主干接入层和末端接入层,同时新建主干光缆,搭建全新的乡镇农村本地传输接入层。通过部分地区的实际运行情况,该策略能够很好满足本地接入层的传输容量、安全性及可扩展性。In view of LTE era, the traditional local transport access layer of towns and vil ages can’t meet the needs of rapid development of service requirement, a research on service development feature of different areas is carried out. An alteration strategy for lo-cal transport access layer of towns and vil ages is presented. In this strategy, local access layer is subdivided into trunk access layer and extremity access layer, meanwhile, new trunk cable is constructed, then, a new local transport access layer of towns and vil ages is build. During the actual operation in some areas, this strategy can wel meet the needs of local access layer ca-pacity, and also can be provided with high security and scalability.
