摘要
随着4G网络建设的重心从室外广度覆盖向室内深度覆盖转变,小基站的部署正在全面展开。首先从宏站的PTN回传方案出发,提出了引入安全网关的小基站回传方案;分析了PON承载小基站业务的优越性,提出了在PTN回传网络基础上引入PON的回传方案。指出了不同回传方案所适用的应用场景。
With the core of 4G network construction is transforming from the outdoor wide coverage to the indoor deep coverage,small cells are being deployed roundly. It started from the macro cells＇ PTN backhaul solution to propose an small cells backhaul solution introducing safe gateway,analyzes the superiority of PON bearing small cell,and proposes a PON solution based on PTN＇s backhaul network. It also pointed out appropriate application scenarios for different solutions.
