Global connectivity depends on networks working together. From international roaming to cross-border mobile services, operators rely on infrastructure that allows different networks to communicate reliably.

As mobile networks evolve, interoperability, signaling, and flexible infrastructure remain essential to keeping these connections working.

From 19th – 22nd October 2026, the telecom community will gather in Dublin, Ireland, for GSMA WAS #24 at Aviva Stadium. PAiCore Technology will be there, represented by Celeo Arias and Ellen Velickovska, connecting with industry stakeholders to discuss the technologies and partnerships supporting international connectivity.

Supporting Interoperability Across Networks

Behind international roaming and cross-network services are signaling systems and routing technologies that enable operators to exchange information.

As networks evolve across legacy infrastructure, 5G, cloud environments, and API-driven services, operators must maintain compatibility while adapting to new technical requirements.

PAiCore develops open-source solutions across several areas of telecom infrastructure:

• Signaling Transfer Point (STP): Routes SS7 signaling traffic.
• Diameter Routing Agent (DRA): Routes Diameter messages between network elements.
• SMSC and USSD Gateway: Support mobile messaging and USSD services.
• Network API Gateway: Connects modern applications with telecom signaling capabilities.

These solutions address different network requirements while giving engineering teams access to technology they can explore and build upon.

An Open Approach to Telecom Infrastructure

PAiCore’s open-source approach gives developers and engineering teams the freedom to inspect, use, and build upon its telecom technology. For organisations requiring additional assistance, technical support and enterprise capabilities are also available.

At GSMA WAS #24, PAiCore will exchange perspectives with operators, roaming partners, and technology providers on the evolving needs of international connectivity.
