B.10 Example analysis for PCRF and SPR

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

1. A PCRF (in non-UDC Networks) does not store user data (while no session is ongoing); on the other hand an SPR does not perform application logic. It seems that the concept of separating application logic from user data (see step 1) is already in place.

2. Also step 2 (direct provisioning of user data in the SPR rather than via PCRF) seems to be already in place.

3. Also step 3 (combining several SPRs to a logically unique database) is applicable.

4. Parallel sessions in two different PCRFs needs further study.

Step 4 may not applicable.

In summary steps 1, 2, and 3 are applicable and provide some benefits. Applicability of step 4 may provide further benefits but it is for further study.
