Roaming
Cellusys Roaming enables mobile operators to optimise and control inbound and outbound roaming through intelligent Steering of Roaming, traffic validation, routing control, and near real-time performance visibility.
Operator challenges
- Limited control over outbound roaming traffic distribution
- Suboptimal Steering of Roaming leading to revenue leakage or missed commercial targets
- Inconsistent partner performance across visited and home networks
- Lack of real-time visibility into roaming traffic behaviour and quality
- Discrepancies between commercial agreements and actual traffic routing
- Operational complexity across consumer, enterprise, and IoT roaming segments, and hybrid legacy/IP environments
How the platform works
The platform integrates within core roaming signalling and IP interconnect layers, interfacing with SS7, Diameter, and GTP environments. Configurable policy rules apply Steering of Roaming decisions in real time based on commercial agreements, performance thresholds, and quality metrics.
It continuously monitors signalling and data traffic, validating events, identifying routing inconsistencies, and providing near real-time visibility into partner performance and traffic distribution. Data traffic control is handled through GTP-Proxy in IP-based roaming environments.

Deployment
Deployable within core signalling and IP interconnect environments, supporting both legacy SS7 and IP-based roaming architectures. Integrates with STP, DRA, billing, clearing, and commercial reporting systems, with REST API support for external connectivity.
Available on-premises or as a managed service. Deployment typically follows phased implementation aligned with operator architecture, including configuration, integration, testing, and operational handover. Policy rules and controls are designed to be configurable by operators without requiring vendor involvement for day-to-day adjustments.
