Hope you get the information what you are looking for

Hi Chinmoy, I registered to the website and clicked on the link you shared but I did not get Gx interface logs. If you are able to download then can you please send me logs to my email id - vimal_bhumca06@yahoo.co.in

Thanks for your quick reply.

Is it possible to use Credit-Control-Failure-Handling in Gx interface?

Is it possible to use Credit-Control-Failure-Handling AVP in Gx interface. If so, how?

My query is when PCEF sends a CCRequest to PCRF and PCRF does not reply anything, so in that case will that be possible to use Credit-Control-Failure-Handling(CCFH) avp.

Does this behavior allowed as per 3GPP Standards or its upto the customization of the product. Any reference are highly appreciable.

CCR-U loop in Gx interface

1) Assume that susbcriber is having lower specifications handset which can support of 300kbps in 2G radio, when susbcriber creates a session/starts browsing then GGSN will send QOS in CCR-I as 300kbps & PCRF will reply CCA-I as 400kbps (Assume that at PCRF end 400kbps plan is configured), subscriber can browse successfully & no extra messages in network

2) Assume that susbcriber is having lower specifications handset which can support of 300kbps in 2G radio, when susbcriber creates a session/starts browsing then GGSN will send QOS in CCR-I as 300kbps, PCRF will reply CCA-I as 400kbps (Assume that at PCRF end 400kbps plan is configured), subscriber can browse successfully, after sometime GGSN send CCR-U1 messages with event trigger revalidation timer expired & qos as 300kbps, PCRF will again execute policy function & allocate 400kbps in CCA-U1. Now GGSN again sends an CCR-U2 with 300kbps QOS-CHANGE as event trigger & again PCRF send 400kbps in CCA-U2, like this it go on loop.

/IPCANTYPE=3GPP-EPS mode/
Concern is why same qos send in case-1 is no loop messages, where as loop in case-2

How QCI_X(where X = 1,2,3,4,5,6,7,8,9,65,66,67,68,69,70) is selected by PCEF for CC-Request in Gx interface

How PCEF decide which QCI_X(where X = 1,2,3,4,5,6,7,8,9,65,66,67,68,69,70) value need to be send to PCRF.
What is the significance of so many QOS-Class-Identifiers?
Even 3GPP 29.212 doesn't define any reason for classification between different QOS-Class-Identifiers.

Handle error scenarios in the PCRF (over Gx interface)

I am trying to handle all the error scenarios seen while testing the Gx with the third party. As of now I had coded for just the successful scenarios.

I am looking for some of inputs on these error scenarios and how to proceed and exit gracefully (rather than crashing the code)

  • Dynamic rule config with wrong parameters., PGW sends CCR with the CCR type=TERMINATION_REQUEST. How can PCRF respond (just log error and comeout ?)

  • Static rule config with the "wrong rule name". When the PCRF sends CCA-I with the wrong rule name, PGW sends CCR-U with the Charging Rule Report with the "Rule-Failure-Code" as "Unknown Rule Name". In this case remove those rules and continue OR just comeout with just logging error)
