卫星通信系统当前主要采用集中方式部署核心网,存在单点故障风险,系统可靠性和扩展性不足、整体性能受限。大型低轨通信星座系统,服务的用户数量和业务量大幅增加,对系统可靠性和整体性能提出了更高要求。对此,基于低轨星座“天基基站+地面核心网”的典型布局,提出一种多节点分布的地面核心网架构。重点针对低轨星座多节点核心网落地选择问题和用户管理问题提出解决思路,并设计用户漫游和主备切换的基本流程。该分布式核心网具备业务分担和备份接替的能力,缓解了单节点核心网的承载压力,提高了系统可靠性和整体性能。
Currently
satellite communication systems mainly deploy core networks in a centralized manner
which poses risks of single point failure and limits system reliability
scalability
and overall performance. The large-scale low-orbit constellation communication system has seen a significant increase in the number of users and business volume
which puts higher demands on system reliability and overall performance. In response
a multi-node distributed ground core network architecture based on the typical layout of low-orbit constellation "space-based base station + ground core network" was proposed. The solutions to the problems of landing selection and user management in multi-node core networks for low-orbit constellations were proposed
and basic processes for user roaming and active/standby switching were designed. The distributed core network had the ability to share services and backup
which alleviated the load pressure of single-node core networks and improved system reliability and overall performance.
