Study on restoration of profiles related to UDR
The present document identifies impacts to services offered to subscribers served by 5GC in case profiles at UDR are corrupted, lost, or became inconsistent, and addresses how the impact can be minimized. The document will focus on the following aspects:
- Clarify the necessity on defining procedures for 5GC to allow NFs, e.g. AMF, SMF, SMSF, NEF, PCF, AUSF to trigger correction and synchronization of temporary data within the UDR in case any corruption, loss, or inconsistency of data in UDR takes place, along with how NFs detect such case;
- Whether similar issue needs to be addressed between other NFs;
- Provide candidate solution(s) to solve the issue; and
- Evaluate the candidate solution(s) and recommend any changes to specifications if identified.
