5G无线接入网（RAN）架构提供了一个分离选项，即gNB中央单元（gNB- cu）连接到一个或多个gNB分布式单元（gNB- du）。CU与5G核心网（CN）相连，通过软件容器实现功能虚拟化。此演示展示了在不丢失服务的情况下，在云原生5G网络中实时迁移容器化中央单元（CU）组件。在弹性方面，虚拟功能热迁移可以避免承载gnb -虚拟化CU （gNB-vCU）的服务器发生故障，否则可能导致UP （User -plane）流量中断和UE （User Equipment）断连。与传统的备份/恢复选项相比，建议的gNB-vCU容器实时迁移技术将最终用户服务临时停机时间减少了50%。
The 5G Radio Access Network (RAN) architecture provides a split option, whereby a gNodeB Central Unit (gNB-CU) is connected to one or more gNB-Distributed Units (gNB- DUs). The CU is in turn connected to the 5G Core Network (CN) and its functions can be virtualized through software containers. This demonstration showcases live migration of a containerized Central Unit (CU) component in a Cloud-native 5G network without loss of service. In terms of resiliency, virtual function live migration can circumvent the failure of the server hosting the gNB-virtualized CU (gNB-vCU) that would otherwise cause an interruption of user-plane (UP) traffic and disconnection of User Equipment (UE). The proposed gNB-vCU container live migration technique reduces the end-user service temporary downtime by 50% when compared to the traditional backup/restore option.
