中国电信“固移融合”背景下打造新型STN承载网的探索

Exploration of Building a New STN Bearer Network under the Background of"Fixed Mobile Convergence"of China Telecom

根据5G承载特点及STN存在的网络问题,结合Spine-Leaf新型城域网架构,通过对现网STN网络进行优化改造,打造面向综合承载的新型网络,节约设备投资及中继光缆纤芯占用,实现网络能力、效能双提升。新型承载网络可满足IP城域网、基站业务回传、政企业务综合承载,有助于简化网络结构、实现运维集约化。

According to the characteristics of 5G bearing capacity and network problems existing in STN network,combined with the"Spine-Leaf"new man architecture,the existing STN network is optimized and transformed to create a new network oriented to comprehensive bearing capacity,saving equipment investment and relay cable core occupancy,and realizing the double improvement of network capacity and efficiency.The new bearer network can meet the requirements of IP man,base station service transmission,and comprehensive carrying of government and enterprise services,which helps simplify the network structure and realize intensive operation and maintenance。
