AI Technical Summary

Technical Problem

Existing digital twin models are ill-suited to adapting to the highly dynamic topology changes, spatiotemporal asynchrony of data from heterogeneous devices, and sudden interference in satellite internet, resulting in discrepancies between virtual simulations and physical network conditions, and a single evaluation dimension with insufficient dynamic adaptability.

Method used

By employing a virtual-real fusion registration method, a multi-dimensional index evaluation model is constructed through real-time sensing of global satellite internet network data. Combined with a multi-factor dynamic evolution model, time synchronization interpolation and simulation correction are performed to establish a basic routing topology map of the satellite network, construct a dynamic routing model, and conduct multi-factor fusion and virtual-real fusion simulation.

Benefits of technology

It enables accurate simulation and assessment of satellite internet, improves the accuracy of global situational awareness, can detect network faults in advance, optimize resource allocation, and ensure network stability and service quality.
