5G NSA共建共享模式下不同边界场景移动性策略研究

Study on Mobility Strategies of Different Boundary Scenes in 5G NSA Co-construction and Sharing Mode

随着中国电信和中国联通共建共享网络建设持续推进,5G NSA网络覆盖范围不断延伸。中国电信和中国联通各自承建的NSA网络内部,以及中国电信和中国联通承建网络之间,因网络制式、频段、覆盖程度不同,会产生多种不同的边界。详细分析NSA共建共享中由中国联通承建时可能出现的各种边界场景,针对不同场景提出相应移动性策略。将相关策略应用于现网,通过现网实际验证,找出不同边界场景移动性策略和方案的最优参数配置,确保中国电信和中国联通5G NSA和4G终端能流畅穿越不同边界,且感知不受影响。

With the continuous promotion of 5G mutual building and sharing of China Telecom and China Unicom,CT and CU 5G NSA network coverage continues to expand.There will be many kinds of boundaries in CT and CU 5G network,that caused by different network systems,frequency bands and coverage.It analyzes all kinds of possible boundary scenarios in the co-construction and sharing 5G NSA network,and proposes corresponding mobility strategies for different scenarios.The relevant strategies are applied to the existing network,and the optimal parameter configuration of mobility strategies and schemes in different boundary scenarios is found through the actual verification of the existing network,which ensures that 5G NSA and 4G terminals of China Telecom and China Unicom can smoothly cross different boundaries without affecting user perception.
