4G基站低频系统共享可行性方案探讨

Discussion on Feasible Scheme of 4G Base Station Low Frequency System Sharing

以5G网络共建共享为契机,运营商间同步开展4G网络的共享实验。鉴于两运营商均以低频系统800M/900M作为基础覆盖层,在该频段的基站共享,不仅可迅速提升两方覆盖质量,并且将节省大幅建设投资和运营成本。针对800M/900M低频基站互开共享载波,从接入、数据/语音业务测试、切换、KPI指标变化等方面对低频系统共享的可行性进行组网验证,为在4G网络的进一步共享提供参考。

Taking 5 G network co-construction and sharing as an opportunity, network operators simultaneously start 4 G network sharing experiments. Since both two operators take 800 M/900 M low-frequency base system as the basic coverage layer, sharing base stations in this frequency band can not only rapidly improve the coverage quality of the two parties, but also significantly save construction investment and operating costs. For 800 M/900 M low-frequency base stations carriers mutual open sharing,the feasibility of low-frequency system sharing is verified in terms of access, data/voice service testing, handover, and KPI index changes, to provide a reference for further sharing in 4 G networks.
