The Challenge

Around the world, the presence of international users, or roamers, on national networks is increasing. To avoid complex interoperability problems with 4G and 5G networks, operators are relying on the roamers’ home networks to manage their calls to home and abroad.

This, however, creates a blind spot in the network. The lack of visibility of home-routed traffic prevents operators from analyzing usage, accurately attributing charges, and identifying fraudulent activities.

More importantly, the roaming loophole bypasses traditional lawful intercept capabilities that can be exploited by both national and foreign criminals, creating a significant gap for both intelligence gathering and network compliance.

VigilanceTM Roamer Collect from Illuminate uses key interfaces within the operator’s network to close the roaming gap without the need to approach the roamer’s home network. This ensures the ability to track international usage, detect anomalous behavior, and supports full compliance with legal regulations.
