摘　　要：面向5G建设需求,通过对中国联通南方和北方城市本地基础网络架构资源进行调研分析,并对比CRAN和DRAN建设模式的TCO成本,初步总结出以"综合接入节点+DU集中点"为目标节点的基础资源储备思路,提出本地基础网络架构资源储备下阶段工作应以综合接入区为单位,通过"定点、连线、成面"步骤,全面梳理机房资源和主干光缆资源,提前进行5G基础资源储备。It aims at 5G construction requirement,through the research and analysis of the local network infrastructure resources of ChinaUnicom＇s southern and northern cities,it compares the TCO cost of CRAN and DRAN construction model,summarizes thebasic resource reserve idea of ＂integrated access node ＋DU centralized point＂ as the target node. It puts forward that the localnetwork Infrastructure resource reserve should take the integrated access area as the unit,through the ＂fixed point,connection,surface＂ step,comprehensively combing the computer room resources and backbone optical cable resources,to reserve5G basic resource in advance.

关 键 词：本地基础网络架构 资源储备 综合接入点 TCO成本
