5GC Unified Data Management (UDM) Certified

In Tejas Networks 5G Core (5GC), UDM (Unified Data Management), acts as the "subscriber brain" — centralizing management of subscriber identity, profiles, and secure authentication to enable flexible, efficient, and advanced 5G services.

UDM interacts with NFs such as AMF, SMF, and AUSF via the Service-Based Interface (SBI) to deliver secure authentication (credential generation, SUCI/SUPI handling), access authorization, support for network slicing (S-NSSAI) and personalized services (QoS/entitlements).

It supports interworking with legacy 4G HSS as defined in 3GPP TS 23.632

UDM serves as the frontend logic layer, with persistent subscriber data stored in the backend UDR. Tejas Networks 5G Core -UDM is Cloud Native Network Function compliant to 3GPP Standards.
