Design of Ground Distributed Core Network Architecture for Large Low Earth Orbit Communication Constellation

Blog Article

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 makeup palette 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 Cat Beds single-node core networks and improved system reliability and overall performance.
