Figure-7.6: Procedure for update of the subscription information in the PCRF

1. The SPR detects that the related subscription profile of an IP‑CAN session has been changed.

2. If requested by the PCRF, the SPR notifies the PCRF on the changed profile.

3. The PCRF responds to the SPR.

4. The PCRF stores the updated profile.

5 If the updated subscriber profile requires the status of new policy counters available at the OCS then an Initial/Intermediate Spending Limit Report Request is sent from PCRF as defined in clauses 7.9.1, and 7.9.2. If the updated subscriber profile implies that no policy counter status is needed an Intermediate Spending Limit Report Request is sent from PCRF, if this is the last policy counter status Final Spending Limit Report Request is sent from PCRF as specified in clause 7.9.3.

6. PCRF makes an authorization and policy decision.

7. The PCRF provides all new PCC decisions to the PCEF and BBERF (if applicable), using the PCRF initiated IP‑CAN session modification procedure in clause 7.4.2. The PCRF also provides all new ADC decisions to the TDF, if applicable.
