We steer outbound roamers to preferred partner networks in real time across 2G, 3G, 4G LTE, and 5G SA, maximising revenue, enforcing agreements, and eliminating leakage.
Challenges
Outbound roamers often land on non-preferred networks, reducing the value of bilateral agreements and increasing settlement costs. Without real-time control, traffic distribution becomes commercially inefficient.
Visited networks actively disrupt steering using techniques like RNA Swap and Fake Location Updates. Without detection, these reduce steering effectiveness while remaining invisible operationally.
Legacy SS7 and Diameter-based steering cannot support 5G Standalone. Operators need UDM integration, SEPP-based enforcement, and slice-aware steering to maintain control.
Managing hundreds of agreements across markets through manual configurations slows execution, increases risk, and leads to missed commitments.
Steering VoLTE or VoNR subscribers to incompatible networks leads to call failures and degraded experience, directly impacting customer satisfaction.
Product Overview
We intercept registration signalling in real time across MAP (2G/3G), Diameter S6a (4G LTE), and HTTP/2 SBI (5G SA), and apply policy-driven steering decisions within milliseconds. These decisions are based on partner priority, subscriber segment, usage commitments, QoE, and service capability.
We also extend steering into 5G SA with UDM integration, SEPP-based enforcement, and slice-aware control, while detecting and mitigating anti-steering behaviour in real time.
The outcome is simple:
Capabilities
Our integrated Border Roaming Gateway (BRG) intercepts MAP, Diameter S6a, and HTTP/2 SBI registration messages in real time, providing a secure, standards-compliant control point for steering decisions across 2G, 3G, 4G LTE, and 5G SA without impacting subscriber experience.
We define steering rules across partner priority, load distribution, QoE, usage commitments, subscriber segments, and service capabilities—giving full control over traffic distribution.
We enable 5G-native steering using UDM-based preferred network delivery and SEPP-based enforcement to control outbound roaming from day one.
We detect and neutralise RNA Swap, E.164 manipulation, and Fake Location Update attacks, preserving steering effectiveness and providing actionable visibility.
We match subscriber and network capabilities to ensure voice services work as expected, reducing failures and improving roaming experience.
We steer based on slice availability using S-NSSAI mapping and substitution, enabling control and monetisation of 5G enterprise services.
We push preferred and forbidden network lists directly to SIMs, reinforcing steering decisions and reducing repeated signalling overhead.
We provide real-time dashboards, standard reports, and integration with existing NOC tools for continuous monitoring of steering performance and compliance.
Process
We capture registration signaling through our Border Roaming Gateway (BRG) across 2G, 3G, 4G, and 5G as subscribers attempt to connect in a visited network.
We apply multi-dimensional policies based on commercial agreements, subscriber profile, QoE, and service capability.
We steer the subscriber to the preferred network using signalling responses, SIM updates, or hybrid enforcement in 5G SA.
We track outcomes in real time through dashboards, reports, and alerts, ensuring continuous optimisation and compliance.
Results
We ensure traffic consistently flows to preferred partners, improving the commercial return from roaming agreements.
We convert traffic-share commitments into measurable, enforced outcomes with real-time visibility.
We shift traffic away from high-cost networks and meet usage commitments automatically.
We maintain steering effectiveness even in the presence of anti-steering behaviour.
We extend full steering control into 5G SA with UDM, SEPP, and slice-based capabilities.
We automate steering execution, monitoring, and reporting, removing dependency on manual processes.
