面向5G业务的乡镇SPN规划及组网架构

切片分组网凭借其技术优势已成为5G业务主流传送承载网的技术之一。伴随乡镇、农村5G业务高速发展及各类5G垂直行业对5G业务的更高更广需求，前期在市区县城区域部署的SPN已无法完全满足业务需求。为满足乡镇、农村的5G业务发展需求，需考虑将SPN下沉至乡镇层级。基于乡镇5G业务发展趋势，综合考虑乡镇SPN建设条件，结合SPN架构、组网拓扑等条件，搭建乡镇SPN架构模型并深入分析获得某地市实际应用场景建设方案，为后期乡镇SPN建设提供参考和思路。

SPN planning and networking architecture in townships for 5G services

slicing packet network (SPN) has become one of the technologies of the mainstream transmission bearer network for 5G services with its technical advantages.Along with the rapid development of 5G services in towns and rural areas and the higher and broader demand for 5G services from various 5G vertical industries, the SPN deployed in urban and county areas in the early stage could no longer fully meet the service demand.To meet the demand for 5G service development in townships and rural areas, SPN need to be considered down to the township level.Based on the development trend of 5G services in townships, the SPN construction conditions were comprehensively considered in townships, combined with SPN architecture, network topology and other conditions, a township SPN architecture model was built and an in-depth analysis of the actual application scenario construction plan was obtained in a local city, providing reference and ideas for the later township SPN construction.
