Policy Charging and Rules Function (PCRF) - Subscriber Profile Repository (SPR) "DIAMETER_ERROR_USER_UNKNOWN" -
Last updated on SEPTEMBER 06, 2016
Applies to:Oracle Communications Subscriber Data Management (SDM) - Version SDM 9.0.5 and later
Information in this document applies to any platform.
Performing the test for the new architecture: it is with the DSR between the GGSN and PCRF (GGSN-DSR DSR-PCRF-SPR) and we get the result "DIAMETER_ERROR_USER_UNKNOWN" in the SNA that sends the SPR.
The configuration on the PCRF/SPR is (The SNA enable in the SPR; Combine Lookup, State & Quota enable in the MPE).
The issue could be identified, as follows:
• Scenario #1
The SPRB working as SystemController & DataAccess
The SPRA processing traffic in Sh interface.
The SPRA responds in the SNA "DIAMETER_ERROR_USER_UNKNOWN " without user profile and creates the user profile in the database.
This causes a different behavior in the policies, consequently affects users.
• Scenario #2
The SPRA working as
The SPAR processing traffic in Sh interface.
The SPRA responds in the SNA "DIAMETER_SUCCESS" with empty user profile and make the profile in the database.
In this case, the Policies are executed correctly
