Invalid origin Host error AVP due to DRA originating RAR

Here is the scenario in our Customer environment :

For VoLTE Gx environment, our Customer use Cisco PGW, Oracle DRA and Openet PCRF.

Their DRA has sessions/subscribers database.

In order to avoid ghost sessions on DRA, they have implemented a feature to send RAR message to PGW from DRA to have a confirmation that the user is still using the services and the session is still alive.

As per PCEF (ims-auth service) current design is :

in a DRA setup, RAR from any origin-host is accepted
in non-DRA setup RAR is accepted only from configured peer

The PCEF (ims-auth service) consider the setup as DRA or non-DRA based on the origin-host received in CCA-I or RAR.

DRA setup = If the Origin-Host received in CCA-I/RAR is not the same as the directly connected/configured peer (in diameter-endpoint). The DRA mode is selected by PCEF and we accept RAR from any origin-host.

Non DRA setup = If the Origin-Host received in CCA-I/RAR is the same as the directly connected/configured peer. The non DRA mode is selected by PCEF and we accept RAR only from primary or the secondary server of the selected row in the diameter host-select table.

The Problem is :

• When the origin-host is changed using RAR, and it is now the

same as the directly connected/configured peer ,the directly connected peer is not considered as a DRA from PCEF perspective.Then when the RAR received from a different peer than the one configured, is rejected.

• It also the same case for CCR-T which is sent to the new origin-host received in the RAR .

Please could you advise some best practice so that PGW (PCEF) accept RAR sent from any origin host ?
