On Oracle Communications Network Charging and Control (OCNCC) Version 4.4.1, it is observed that during a Specialized Resource Point(SRP) interaction call, the P-Charging-Vector(PCV) header is not included in the INVITE messages sent by the Session Control Agent(SCA) to the final destination.
While interacting with IMS environments, the Softswitch network elements will include a P-Charging-Vector header in the INVITEs they send to the OCNCC Service Logic Controller(SLC).
OCNCC forwards these PCV headers it receives in the INVITEs it sends to the soft switch network elements in most cases, which includes complex cases where multiple INVITES are involved when the Attempt Termination feature nodes are used and calls are re-directed to new destinations, in case of a Busy or Route Select Failure or No Answer responses etc.
However an exception has observed for this behavior when an SRP is involved in a call using an Selection Dependent Routing(SDR) Feature Node.
When an SRP is involved in the call, the INVITE from the Softswitch to the SLC contains a P-Charging-Vector header as below,
The SCA includes this header in the INVITE it sends to the SRP as well. The SCA then send another INVITE after the SRP interaction is completed. However this INVITE sent by the SCA to the final destination, doesn't include this PCV header.
Due to this the Softswitch Network Elements can't identify the corresponding call associated with this INVITE and not able to combine the call records together.
