摘要
5G前期建设主要采用NSA组网,后期会演进到SA组网。由于5G使用高频,覆盖性能较弱,SA组网建设投入巨大,单站运营成本非常高。中国电信和中国联通在4G时代已经就共享展开合作,5G时代双方期望进一步开展通力合作,在节省投资的同时,建立一张有竞争力的网络,发挥“1+1≥2”的效果。阐述了共建共享的需求以及满足需求的技术手段和业务实现。
In the early stage of 5g construction,NSA scheme is mainly adopted,and it will be evolved to SA in the later.Because 5G uses high frequency band and has weak coverage performance,SA network construction investment is huge and single station operation cost is very high.China Telecom and China Unicom have been cooperating on sharing in the 4G era.In the 5g era,both sides hope to further cooperate to save investment and build a competitive network to acheive the effect of"1+1≥2".It expounds the needs of co-construction and sharing,the technical means to meet the needs and service realization.
