1. Interoperability via Multi-Generation Signalling Platforms
- The Challenge: Satellite constellations must communicate with thousands of different terrestrial Mobile Network Operators (MNOs) using various network standards (from legacy SS7/4G to modern 5G).
- The Solution: Squire Technologies’ flagship platform, Sigla acts as a multi-generation translation layer. It bridges different signalling protocols (such as SS7, Diameter, and HTTP/2). This allows a single LEO or GEO network gateway to interconnect seamlessly with legacy or next-generation terrestrial networks anywhere in the world.
2. Seamless 5G Core Integration at Ground Stations
- The Challenge: Next-generation LEO and GEO networks are designed around 5G architecture to support high-throughput, low-latency data and IoT services. However, ground gateways often utilize legacy backhauls.
- The Solution: Squire provides 5G Interworking Functions (IWF), HTTP-2 Signalling Controllers, and Service Communication Proxies (SCP). When deployed at satellite ground stations, as seen in past upgrades for operators like Globalstar. These core products transform satellite infrastructure into modern IP/5G networks, maximizing throughput and reducing structural latency.
3. Convergent Monetization and Global Roaming
- The Challenge: For LEO/GEO growth to be commercially viable, satellite networks need to support global consumer roaming, enterprise connectivity, and dynamic billing across borders.
- The Solution: By using products like the Diameter Signalling Controller (DSC) and Diameter Routing Agent (DRA), Squire Technologies provides the backend infrastructure necessary for convergent charging. This allows satellite operators to route authentication, authorization, and billing data in real time, making global satellite-to-cellular roaming possible.
4. Direct-to-Cell Integration (VoLTE & Messaging)
- The Challenge: Massive growth in LEO is driven by the race for “direct-to-cell” technology, allowing standard smartphones to connect straight to satellites for voice, text, and emergency messaging.
- The Solution: Squire’s specialized messaging and voice platforms, Mirus and Vozi, alongside their Short Message Service Functions (SMSF), optimize media routing and network security. This gives satellite operators the capacity to handle bursty IoT data, emergency alerts, and consumer text traffic natively on standard cellular bands.
Summary
The emerging orbital telecommunications economy presents a host of opportunities for core network providers. With its armoury of signalling solutions and nearly a quarter of a century of experience, Squire Technologies has the pedigree to undertake complex signalling challenges.
A State of the art Unified Signalling Platform
Sigla brings a homogenous layer to the management and operation of multi-generation networks, freeing operators from the burden of managing multiple core networks, and reducing network complexity and operating costs.
