为更好地满足现阶段各类业务的承载需求,河南联通网络管理中心从河南省无线网的实际和基站维护现状出发,对多种传输网络环境下利用IP RAN与MSTP/SDH混合组网满足基站建维需求进行了研究,验证其可行性,在不改动基站任何硬件连接、不影响网络稳定性并且不需要额外建设投资的前提下,为无线网络建设维护的提质增效提供一种行之有效的解决方案。
1 研究背景
河南省联通移动通信网络规模逐年扩大,截至2020年10月末,河南省联通在网运行的逻辑基站数量已经超过130 000个,物理站址数量超过30 000个。随着4G网络的不断发展,用户对高带宽的手机接入需求越来越多。但实际上,针对联通全球移动通信系统(Global System for Mobile Communications,GSM)的退网以及U900的补充覆盖,相当多用户的业务需求依旧需要3G网络承担,对于回程网的承载需求呈现出爆炸式的增长。目前,部分3G基站的承载仍采用MSTP(Multi-Service Transfer Platform,多业务传送节点)技术/SDH(Synchronous Digital Hierarchy,同步数字体系)技术。……
