AI Technical Summary

Technical Problem

In satellite routing and control systems, when the coverage edges of multiple satellite networks overlap too little, frequent signal fluctuations cause ping-pong handover, leading to degraded communication quality, wasted network resources, and increased terminal power consumption.

Method used

By monitoring satellite signal quality and orbit prediction, and combining fuzzy logic controllers and machine learning models, the optimal handover target is dynamically selected, unnecessary handovers are restricted, multi-node redundancy and communication degradation mechanisms are adopted, and the handover time is adjusted according to the signal recovery probability.

Benefits of technology

It reduces communication quality degradation, network resource waste, and increased terminal energy consumption, thereby improving network stability and resource utilization efficiency.

Abstract

This invention discloses a satellite routing control and switching method and system, belonging to the field of satellite communication. The satellite routing control and switching method includes the following steps: monitoring satellite signal quality and collecting satellite data to determine whether a node switch is needed. Triggering conditions include: signal quality degradation below a threshold and communication equipment about to leave the current satellite network coverage area. When a node switch is needed, the optimal switching target is selected from candidate nodes, and the signal quality of the optimal switching target is judged. If the signal quality meets the usage requirements, the beneficial effects of this invention compared with the prior art are: when the overlapping area of ​​the coverage edges of multiple satellite networks is too small and the signal quality is judged to be poor, the invention restricts the switching node, prohibiting arbitrary node switching within a set time. Moreover, the set time is adjusted according to the actual situation to match different situations, reducing problems such as communication quality degradation, network resource waste, and increased terminal power consumption.
