LIMA Idea
An introduction toThe privacy protections in 5G Standalone (SA) networks are a major step forward — but they also create a challenge: how do you associate a temporary identifier like 5G-GUTI with a permanent one like SUPI, especially during lawful interception?
LIMA Idea enables identity correlation in modern 5G networks using 3GPP-compliant methods — bridging the gap between interception tools and network-level identifiers, securely and in real time.
Enable identity lookup & direction finding in 5G
Correlate temporary identifiers with SUPIs to support lawful interception tools like 5G Catchers and Direction Finders — even in ECIES-protected 5G SA networks.
Powered by 3GPP-compliant architecture
Built on the IQF, ICF and IEF functions, using the LI_XER, LI_XQR, and LI-HIQR interfaces for seamless integration with national CSPs and LEA systems.
Centralized Proxy Router for national scale
LIMA’s HIQR Proxy Router removes the need for direct CSP connections — one interface for all SUPI Catchers, reducing technical overhead and complexity.
Built for performance and reliability
Designed for high-throughput environments with real-time response capability — LIMA Idea keeps up with the demands of modern 5G infrastructure.

Use Cases
LIMA Idea
LIMA Idea supports multiple 5G interception scenarios — from identity correlation to real-time direction finding.
01
Identity Lookup
Correlate 5G-GUTI (temporary) identifiers with permanent SUPIs, supporting real-time or offline analysis by LEAs.
02
Direction Finding
Use SUPI-based queries to retrieve the current 5G temporary identifier, enabling live tracking and location correlation.
