The customer had a very high rate of call failures in 5G Non-Standalone (NSA) roaming and approached TOMIA to gain additional insights on their outbound and inbound roaming subscribers.



With a number of 5G Non-Standalone (NSA) agreements in place already, TOMIA’s business intelligence suite harnesses local Sparx campaign management and network signaling probes, to collect inbound and outbound roamers’ movements in 5G networks. The information is collected per network (VPMN and HPMN), on an hourly-based resolution.



Customized to meet the customer’s specific needs, we provide hourly as well as daily reports – in both graphical and tabular formats – which help improve visibility and support future expansion.

In addition, the customer started formulating the interoperability requirements for 5G Standalone (SA) roaming and gained competitive advantages in the process. 5G SA enables differentiation through connectivity and adds value to the B2B and B2C offerings, unlocking new revenue streams. TOMIA conducted a Proof of Concept (PoC) on 5G SA steering in a testing environment to validate the 5G flows and message protocols. The main objective was to design, develop and test an approach for 5G SA active steering, where the Steering of Roaming (SoR) acts over the signaling message flow to control and decides about roamers’ registrations on foreign networks.
