Spatially-Aware NFV Orchestration for Dynamic LEO Satellite Management in 6G Networks

The integration of Low Earth Orbit (LEO) satellite constellations into 6 G networks offers unprecedented opportunities for global connectivity, particularly in underserved regions. However, these non-terrestrial networks (NTNs) face significant challenges, including satellite mobility, frequent handovers, and dynamic resource allocation. This paper introduces a novel GISenhanced Network Function Virtualization (NFV) Management and Orchestration (MANO) framework tailored for multi-LEO satellite constellation coordination. By embedding Geographical Information Systems (GIS) into the ETSI MANO architecture, the proposed framework enables resource allocation, dynamic scaling of containerized network functions, and seamless handovers across satellites. The system leverages Kubernetes-based orchestration and a Satellite Mobility Manager to optimize service deployment based on real-time geospatial data. Experimental validation using a simulated multi-satellite testbed, with three LEO satellites, demonstrates the framework's ability to maintain service continuity, enhance resource utilization, and ensure seamless communication during satellite transitions. These results highlight the potential of GIS-driven NFV orchestration as a foundational solution for efficient NTN management in 6 G networks.
