B.7 Step 5 – Converging user data in the UDR

23.3353GPPRelease 17Stage 2Technical realization and information flowsTSUser Data Convergence (UDC)

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

It is believed to be beneficial when the user data outsourced by several nodes are not stored separated within the UDR but are somehow converged:

This step is purely UDR internal and therefore out of scope of CT4 standards, and not further looked at in this annex.
