There is one use case here. PCEF has sent CCR (due to IP-CAN session modify) to PCRF and it again sends CCR to (due to another update) without receiving previous CCA. What should be the behavior ?

Looking at interoperability issues.
The CCRequest message sent from PGW to PCRF during attach. Does the CCA sent back from PCRF to PGW needs to have TFT info?

Hi,

I am going through the spec 3gpp 29.219(Sy interface) and trying to understand the call flow and AVPS between the OCS and PCRF.

The PCRF sends the the list of Policy counters to OCS initially and OCS will store it against the Sy session. How does the Counter identifiers be identified uniquely b.w OCS and PCRF ?

Because the spec says, If the OCS determines that any policy counter identifiers are invalid, the OCS shall return a response with the Result-Code AVP set to DIAMETER_INVALID_AVP_VALUE.

But my doubt is, how the Policy counter Ids are known across the OCS and PCRF.

Any help in this area is very helpful

Thanks
