Global Satcom Operator

A global satellite communications operator delivering resilient, multi-orbit connectivity solutions to enterprise and government clients worldwide. By integrating non-geostationary capacity with high-capacity space assets, the company offers high-bandwidth, low-latency data transport across remote land, maritime, and aviation sectors. Its network architecture provides secure, high-availability connectivity for telecommunications operators, offshore industries, and critical infrastructure beyond the reach of terrestrial networks. 

Why Traditional SLAs Struggle with LEO 5G?

The customer operates a massive Low Earth Orbit (LEO) satellite constellation, providing Non-Terrestrial Network (NTN) RAN as a Service to wholesale Distribution Partners. However, integrating this highly dynamic space infrastructure with traditional terrestrial 4G/5G Core networks presents massive operational challenges. Unlike traditional geostationary systems, LEO constellations consist of satellites distributed across synchronized orbital planes moving at thousands of kilometers per hour. To succeed in the competitive B2B wholesale market, the company must ensure its services deliver the predictability and performance of standard terrestrial telecom products.

Traditional telecom operators expect standard Service Level Agreements (SLAs) based on fixed geographic areas. Because LEO satellites function as "fast-moving cell towers," measuring Quality of Service (QoS) using traditional terrestrial tools is virtually impossible.

The main challenges included:

• Complex Multi-Vendor & Multi-Domain Ecosystem: The customer operated in a highly fragmented environment where the space segment, NTN RAN, and terrestrial Core/WAN were managed across separate third-party partners. This structure resulted in siloed operational domains and dispersed event monitoring. Crucially, the operator lacked a unified way to correlate data across highly mobile User Terminals, active and passive service quality probing, centralized ITSM inventory and ticketing workflows, and external Business Intelligence data warehouses for SLA tracking.
• Unclear Root Cause Identification: When a service drop occurred, it was difficult to identify if the root cause lay within the terrestrial core, the WAN, or the moving satellite.
• Intense Migration Timeline: Compounding these technical challenges was an incredibly intense timeline to migrate assets from the customer’s legacy infrastructure to a new company within a strict deadline.

To succeed, the company needed a unified service assurance solution that could bridge the gap between space complexity and terrestrial telecom standards under a strict deadline.

How to Enable Terrestrial-Grade SLAs for LEO Networks?

To address these multi-domain hurdles, Comarch Communications proposed a future-oriented strategy that adapted its well-established terrestrial network assurance platform to the unique physics of a non-terrestrial network (NTN). This approach was designed to replace legacy, fragmented assurance modules that forced operations teams into manual troubleshooting, aligning the system directly with LEO satellite dynamics.

The proposed strategy focused on:

• Unified End-to-End Architecture: Replacing fragmented monitoring dashboards with a single, consolidated platform that acts as a translation layer, converting complex aerospace telemetry into standard terrestrial telecom reporting.
• Real-Time Live Perspective: Delivering complete situational awareness by continuously correlating and visualizing user terminals, active satellites, and ground network nodes in a single, dynamic view.
• Agile, Cloud-Native Deployment: Overcoming the strict transition deadline by implementing a highly collaborative, agile model hosted on secure public cloud infrastructure.
• Open Multi-Vendor Integration: Bridging operational silos by closely coordinating with the customer’s internal teams and third-party technology partners to integrate diverse network components into a unified interface.

This holistic approach successfully abstracted the underlying complexity of orbital mechanics, allowing the operator to package raw space capacity into standard, SLA-backed wholesale products that look and behave like traditional terrestrial connectivity.

Which Comarch Communications OSS Solution Was Deployed?

The implementation of Comarch Communications OSS introduced a powerful set of capabilities to the operator’s operational environment. The solution comprises several core modules, including Fault Management and Performance Management.

Key elements of the implemented solution include:

Ephemeris & Dynamic Topology Correlation: The platform integrates satellite ephemeris data, such as exact orbital trajectory, altitude, and velocity, with real-time network topology. Specifically, the solution monitors dynamic data to track User Terminals as they change Service Regions and Points of Presence (PoPs). By correlating satellite ephemeris data with this dynamic topology, the system seamlessly maps moving satellite footprints to fixed "virtual cells" on Earth, allowing the company to monitor SLAs for specific ground regions

• Automated Multi-Domain Root Cause Analysis (RCA): The system automates RCA by ingesting real-time events across the RAN, WAN, 4G Core, and satellite domains, drastically reducing time-to-resolution.
• Multi-Satellite Contact Assurance: The system actively monitors and provides RCA for failures during multi-satellite contacts and handovers, ensuring that the "handover carousel" between passing satellites remains invisible to the end-user.
• Weather Impact & Forecasting Correlation: The system performs automated alarm correlation and analyzes real-time weather feeds and forecasts to evaluate the environmental impacts of weather on satellite feeder links (the transport network linking satellites to Earth Gateways). For example, this correlation engine can automatically determine if service degradation is caused by rain attenuation at a remote gateway rather than a technical failure in the terrestrial 4G Core.
• Granular Device Telemetry: The system processes deep end-device data, including User Terminal Specific Stats (UTSS) and signal quality metrics pulled directly from active data streams. This allows operators to isolate regional network outages and pinpoint user terminal dropouts on integrated geographic maps.

What Business Value Did the Solution Deliver?

The deployment of Comarch Communications OSS delivered rapid, transformative results, achieved in a transition period of just seven months.

The primary business and operational outcomes include:

Accelerated Telco-Readiness: By utilizing the Comarch Communications platform to abstract the physics of moving LEO satellites, the satellite operator can easily package its dynamic capacity into standard, easy-to-consume wholesale products for traditional telecom distribution partners.

• Confident SLA Enforcement: The advanced SLA tracking capabilities of the Comarch Communications solution empower the operator to confidently guarantee location-based network performance to enterprise clients, ensuring SLA trust and actively protecting revenue from contractual breaches.
• Frictionless Multi-Vendor Operations: Comarch Communications successfully bridged the operational gaps between separate third-party vendors. The platform's automated cross-domain root-cause analysis significantly reduces OpEx by preventing partner finger-pointing and accelerating incident resolution.
• Proactive Revenue & SLA Protection: Through the Comarch Communications engine's ability to correlate real-time performance threshold alarms with weather forecasting, operators can proactively predict and mitigate service degradations before they violate customer agreements.
• Foundation for the Future: The unified architecture delivered by Comarch Communications has successfully bridged terrestrial and satellite networks, setting the stage for the seamless integration of satellite technologies into the future 5G environment.
