Overview

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.

Table : Call Scenarios from Fixed Network to Mobile Network

ScenariosConditionsResults
1The SBC receives a PCV header with ttc-charging-params parameter with orig-ioi valueThe SBC ignores the received ttc-charging-params parameter value and transparently passes the PCV header with orig-ioi value.
2The SBC receives a PCV header in the 18x response with only term-ioi valueThe SBC inserts ttc-charging-params parameter with fixed value in the outgoing 18x response towards the ingress side.
3The SBC receives a PCV header without ttc-charging-params parameter in the INVITE requestThe SBC inserts the fixed value of ttc-charging-params parameter value in the outgoing INVITE request.
4The SBC receives a PCV header with ttc-charging-params parameter in the 18x responseThe SBC ignores the received ttc-charging-parameter value and sends the PCV header with only term-ioi value towards the ingress side.
5The SBC receives a PCV header with ttc-charging-params parameter in the INVITE requestThe SBC ignores the received PCV header and sends the INVITE request without the PCV header.
6The SBC receives the 18x response without the PCV headerThe SBC inserts the PCV header with the fixed value of ttc-charging-params parameter and sends it towards the ingress side.

Examples

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.
