摘要
Abstract
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 ac-tive/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.关键词
