We have complexity linked to Gy and Gx interfaces.
Let's say that we have two rules configured as static on PGW with :
Rule1= Reports RatingGroup1
Rule2= Reports RatingGroup2
When PCRF install Rule 1 on Gx, the ratingGroup reported by PGW to OCS is RatingGroup1
When PCRF uninstal Rule1 then install Rule2, the ratingGroup reported by PGW remain RatingGroup1 till a Gy trigger is reached (revalidation time, GSU consumption...).
Then the problem on our system is that when PCRF change the rules on Gx interface the PGW keep reporting the old rating group on Gy interface ie: Gx change do not lead to a Gy change similtanously. I m wondering if there is a standard behaviour for such a use case?
Thanks a lot
