Abstract
This paper addresses the integration of non-terrestrial networks (NTN) into 6G architecture, focusing on LEO satellite constellations and high-altitude platform stations (HAPS). We propose a multi-layer NTN architecture with AI-driven handover and resource management. Simulation results show that the proposed integration achieves 99.99% coverage availability and reduces handover latency by 40% compared to existing 3GPP NTN solutions.
AI Summary
- Multi-layer NTN architecture integrating LEO satellites and HAPS for 6G.
- AI-driven handover reduces latency by 40% over current 3GPP NTN methods.
- Achieves 99.99% global coverage availability.
- Proposes novel inter-layer coordination protocols for seamless connectivity.
Key Findings
- 1Multi-layer architecture provides resilience through dynamic layer selection.
- 2AI-based predictive handover eliminates service disruption during satellite transitions.
- 3HAPS serve as effective relay nodes between LEO and terrestrial networks.
Industry Implications
Enables the 6G vision of truly global ubiquitous connectivity.
Addresses the digital divide for remote and underserved areas.
Provides a framework for integrating commercial satellite constellations into 6G.
