How to find out roaming or non roaming subscribers from diameter CCR initial request?

Question

Hello,

For the CCR (Initial Request), the CCA is of the above format in my internal testsetup. This seems like Dynamic Rule configuration. I am not sure whether we need to send info like "Flow information" or TFT in CCA. This was answered earlier by Peeyush ( that it is not needed). But wanted to crosscheck the same ?

{ Imp Please Note: This is my initial basic implementation, so only basic necessary AVPs are handled. }

Thanks a lot for the comments and replies

While building Create Session Request message towards SGW node , serving network IE is added into message.
Once the PGW receives CS Request message from the SGW, it fetches "Serving Network" IE from the message and use the information presents within the serving network IE while creating the CCR message as part of IP-CAN Session Establishment Procedure towards the PCRF.

[3GPP-SGSN-MCC-MNC ] AVP of CCR message carries serving network information for an UE. Based on this serving network information, PCRF provides PCC rules to PCEF.
