C-L互操作及其部署方案研究

Interoperability and deployment of C-L network

在LTE建设初期,4G用户回落到3G网络的情况不可避免。C-L互操作部署的优劣将深刻影响4G用户的感知,而HRPD网络升级成e HRPD网络是C-L互操作的前提。对C-L互操作进行了研究,重点研究了C-L数据互操作方案及其现网部署方案,对数据互操作中非优化切换和优化切换2种方式进行了比较分析,提出了e HRPD现网部署中可能存在的问题,并给出了相应的解决方案,可供运营商在网络建设中参考。

In the initial stage of LTE network,it is inevitable that 4G users fall back to 3G network. The quality of C-L interoperation will have a profound impact on 4G users＇ s experience when the HRPD network＇s upgrade to the e HRPD,and the network is a precondition for C-L interoperation. The paper focuses on C-L interoperation,especially the deployment of CL data interoperation,makes analyses on non optimized switching and optimized switching,raises potential problems in current e HRPD network and provides solutions for operators.
