Configurations to Specify VoLTE and SMS Data

You can configure the SBC to use specific data in call data records provided over RADIUS, Diameter and within local CSVs. This ensures that the specified fields

There are two configurations available for specifying VoLTE and SMS data:

  • Subscribe to IP-CAN-CHANGE events
  • Specify Inter-Operator Identifier (IOI)

Subscribe to IP-CAN-CHANGE Events

You can configure a subscription to the IP-CAN-CHANGE event using the Rx interface during the AAA/RAR exchange. To do this, you configure the ip-can-change value to the specific-action-subscription of the applicable ext-policy-config. This causes the SBC to apply the value in the AN-GW-Address AVP from the PCRF as the S-GW IP address.

Note:

If the SBC receives more than one AN-GW-Address AVP from the PCRF, it applies the value in the AN-GW-Address AVP from the PCRF. It also uses the S-GW IP address the first AVP as the S-GW IP address.

Option to Specify IOI

You configure the realm-as-ioi option in the applicable account-config to send the realm name as the IOI in diameter ACRs. If this option is not set, the SBC uses the IOI from the charging vector.

Configure this option using the syntax below. 

ORACLE(account-config)# options +realm-as-ioi

If you type options and then the option value without the plus sign, you overwrite any previously configured options. To add a new option to an options list, pre-pend the new option with a plus sign as shown in the previous example.
