Automation Workflow for Non-Terrestrial Network (NTN) Integration Planning

Manual NTN-terrestrial integration requires extensive simulation of orbital mechanics, propagation models, and interference scenarios across vast geographies. A custom workflow automates this by orchestrating agents that ingest ephemeris data, 3D terrain, and terrestrial network maps to run thousands of coverage and handover simulations in parallel. This compresses the initial design and feasibility phase from quarters to weeks, enabling faster response to coverage mandates or competitive threats.

Over-provisioning terrestrial sites to cover remote areas or under-utilizing expensive satellite capacity are major cost sinks. An AI-driven workflow performs precise gap analysis, simulating where NTN coverage is most cost-effective versus terrestrial expansion. By optimizing the mix, it identifies redundant cell sites and right-sizes satellite service commitments, directly improving CAPEX efficiency and long-term spectrum leasing costs.

Unplanned interference or failed handovers during NTN rollout can degrade service for millions of subscribers. The workflow embeds predictive interference mapping and continuous validation loops. Agents model signal spillover and prioritize configurations that maintain terrestrial network KPIs, routing high-risk scenarios for engineering review. This proactive mitigation reduces rollout-related trouble tickets and protects brand reputation during a high-stakes transition.

NTN integration is not a one-time project but an ongoing operational layer. A custom-built workflow establishes a reusable orchestration platform (using frameworks like LangGraph) that can ingest data from new satellite constellations, ground stations, and updated terrestrial RAN. This turns a complex planning exercise into a durable operational capability, future-proofing the network for LEO, MEO, and GEO additions without restarting from scratch.

The ability to rapidly model the impact of new spectrum bands or satellite partner capabilities becomes a competitive advantage. This workflow provides a simulation sandbox to evaluate auction scenarios or potential vendor technologies. Decision-makers can quantify the coverage and capacity upside of different spectrum holdings or satellite payloads, leading to more confident, data-driven bids and partnership negotiations.

Post-deployment, the workflow evolves from a planning tool into the brain of a live NTN-terrestrial digital twin. Agents continuously compare predicted performance (from the planning models) against real telemetry from both networks. Discrepancies trigger automated diagnostics or re-simulation, enabling closed-loop optimization of handover parameters and dynamic spectrum sharing settings. This shifts operations from reactive firefighting to predictive tuning.

This core agent ingests satellite ephemeris data, 3D terrain models, and terrestrial cell maps to dynamically model coverage footprints and handover zones. It runs thousands of propagation simulations (using models like ITU-R P.681) to predict signal availability and identify potential service gaps or excessive handover ping-pong between satellite and ground networks. The agent outputs geospatial heatmaps and recommended cell parameters to ensure seamless user experience.

An orchestrator agent manages the complex logic of shared spectrum use between NTN and terrestrial services. It continuously analyzes regulatory masks, incumbent protections, and real-time usage telemetry to model interference scenarios. The agent recommends or enforces power limits, frequency offsets, and time-sharing schedules to prevent harmful interference, a critical requirement for operators using bands like n256 (satellite 5G). It integrates with policy control functions (PCF) and spectrum management systems.

This component builds and maintains a unified digital twin of the hybrid NTN-terrestrial network. It fuses live telemetry from ground base stations and satellite modems with the simulated models from other agents. The engine provides a single source of truth for what-if analysis, allowing planners to test integration scenarios (e.g., adding a new LEO satellite plane) and immediately see the impact on coverage, capacity, and interference. It typically integrates with platforms like AWS TwinMaker or Azure Digital Twins.

A control layer that routes high-stakes configuration changes—such as new satellite beam activations or terrestrial power adjustments—through defined approval chains. It presents simulation results, risk assessments, and compliance checks to network engineers and regulatory liaisons via a structured case queue. All decisions, rationales, and overrides are logged to an immutable audit trail, which is essential for demonstrating responsible spectrum sharing to regulators like the FCC or ITU.

This agent continuously monitors key performance indicators (KPIs) from the integrated network, such as NTN link latency, handover failure rates, and interference noise floors. Using statistical and ML-based anomaly detection, it identifies deviations from the planned model—like unexpected signal blockage or a misconfigured satellite payload—and triggers alerts. It routes incidents to the appropriate triage queue (performance engineering, spectrum management, or satellite operations) with suggested diagnostic actions.

A planning and execution agent that sequences the physical and logical deployment of the integration plan. It breaks down the high-level design into executable tasks: generating configuration scripts for terrestrial RAN (Ericsson, Nokia) and satellite modems (iDirect, ST Engineering), scheduling maintenance windows, and coordinating with field operations via integration with systems like ServiceNow or Jira. It manages dependencies and provides rollback procedures to de-risk the live network update process.
