Scenario of OCS/Gy Triggered Bearer Deletion

+3 votes
256 views

Hi Experts,

Can OCS/Gy trigger a bearer deletion by interacting with Gx/PCRF when OCS has Final-Unit-Action AVP value as TERMINATE?
I have tested a scenario where xGW can notify to PCRF with 'OUT_OF_CREDIT' event-trigger and charging-rule will be 'TEMPORARILY_INACTIVE' but not sure about the above scenario.

Hi all,

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

Either the device should drop that AVP with port 0 or It should be handled at OCS level.

Lets say we have counter 1, for a subscriber1, configured in SPR. Lets say this counter1 indicates that the QOS is throttled from 520kbps to 220kbps, when the usage exceeds the lets say 50MB in one month. This is what i understood..Now my query, is does this apply to only GBR bearers in the Subscriber ? And does it apply to all the dedicated GBR bearers ?
How is it applicable for the non GBR bearers ?

Also the PCEF, needs to send the CCR to OCS, i am not able to see how the PCEF is configured to trigger these reports back to OCS. (Is it by the CCA sent by the PCRF, that triggers this reporting from PCEF to PCRF ?)

I am going through the 32.299 and trying to figure out the contents of the CCR message.

Section 6.4.2 lists the AVPS in that message, I am looking for how the PCEF sends the "used bytes" to OCS. The "Multiple services credit control" looks like the one. But need some inputs and help on this AVP. Or please correct me if I am wrong.

Lets say we have a session-0 established for the UE (IPaddress1) for the default bearer. This is when the PGW send the CCRequest(cctype=initial and ccnum=0). Lets say "Policy1" is sent by PCRF in CCA. Does this initial CCRequest has the "Flowdescription" AVP in this ?

Now a dedicated bearer1 is established so CCRequest is sent with (ccrtype =modify and ccnum=1). Lets say PCRF assigns "Policy 2".

Now dedicated bearer 1 is deleted, then what does the PGW send to PCRF ?

Another question: As of now I am storing the list of PolicyRules in PCRF, based on IMSI (IPAddress)..i.e c++ map of IPAddress and PolicyRules. But when the dedicated bearer is removed how do i access the map ? (to find which Policy is deleted)
