AUTH1 | REV5 | REV6 | REV3 | REV1 | REV2 | The SBC Core supports Inter-IMS Network to Network Interface (II-NNI) standard, which uses a proprietary SIP header parameter ttc-charging-params in the P-Charging-Vector (PCV) header for billing. In some II-NNI scenarios, the SBC receives the PCV header without the ttc-charging-params parameter. For example, a SIP INVITE call received from a fixed network to mobile network does not contain ttc-charging-params parameter in the PCV header. However, without this parameter, the SBC cannot generate CDR records. In such scenarios, the SBC acting as IBCF manipulates the ttc-charging-params parameter in the PCV header.
The following call flow is supported when the call is originated from a fixed network to mobile network:
I-SBC → (II-NNI SIP) → I-SBC → IMS Network (Mobile Network)
The table Call Scenarios from Fixed Network to Mobile Network explains the PCV headers without ttc-charging-params parameter in the INVITE as well as 18x responses. The SBC supports adding the default values of the ttc-charging-params parameter to the originating/destination carrier types. The SMM rules are used to manipulate the PCV header for the following conditions.

The table Examples from Fixed Network to Mobile Network provides the examples of the scenarios explained in the table Call Scenarios from Fixed Network to Mobile Network.
