TD-LTE建设初期由于覆盖不足,需要通过4G与3G、2G互操作来保证用户业务感知.系统间互操作可最大化地利用现有3G、2G网络的覆盖优势,对4G网络进行有益的补充.首先对丽水莲都区3-4G邻区进行核查,再对未配邻区的边缘小区进行邻区补全核查.提出了加虚拟邻区的方案,着重解决3G到4G重选的问题.最后通过对比测试,证明了虚拟邻区技术和真实邻区可以达到相同的效果.

Due to the lack of coverage in the early of TD-LTE construction, 4G and 3G, 2G interoperability is needed to ensure the user's service-aware. The inter operation of the systems can maximize the existing 3G and 2G network coverage advantage and give a beneficial supplement to the 4G network. This paper firstly checks the 3-4G adjacent regions of the Liandu District of Lishui, and then completes the checking to the edge regions of the adjacent regions without deployment. The virtual adjacent region scheme is put forward to solve the problem of 3G to 4G re-election. The contrast test proved that virtual adjacent regions can achieve the same effect as real adjacent regions.
