摘　　要：随着全球运营商5G SA网络的规模部署,实现全球范围内5G SA网络的漫游与互通已成为运营商急需解决的问题。相比于5G初期的NSA组网,5G SA作为5G的目标网络架构,其漫游服务具有更高的实用价值。分析了当前5G SA国际漫游业务概况、网络架构、接口协议、互通方案,并对未来5G国际漫游网络部署方案提出建议。With the large-scale deployment of 5G SA networks by global operators,realizing roaming and interoperability of 5G SA networks worldwide has become an issue that operators need to address.Compared with NSA networking in the early stage of5G,5G SA,as the target network architecture for 5G,has a higher practical value for its roaming services.It analyzes the overview of 5G international roaming services,network architecture,interface protocols,and interworking solutions,and provides suggestions on the deployment scheme of 5G international roaming networks.
