The SBC Core includes a signaling profile, NNI Profile, in support of the Inter-IMS Network to Network Interface (II-NNI) and interworking of charging parameters for SIP to/from SIP-I/T/GWGW/ISUP calls. The NNI Profile is attached to a ingress SIP trunk group. To learn more about how the SBC performs SIP to SIP-I and SIP-I to SIP interworking based on the NNI Profile, refer to PCV Interworking Enhancement.

Info

The SBC supports up to 32 NNI profiles. 

To View NNIProfile

On the SBC main screen, navigate to All > Profiles > Signaling > NNIProfile.

The NNIProfile window displays.

NNI Profile Parameter Descriptions

Parameter DescriptionLength/RangeParameter Description
Name1-23 characters

The name of the NNIProfile used to control SBC interworking of charging parameters for SIP to/from SIP-I/T, GW-GW and ISUP calls. The NNI Profile is attached to a SIP trunk group.

Charge Area Information(ASCII 0-9)A 5-digit value representing the charge area Information that applies to calls establishing the INVITE.
 Additional Party Category First

N/A

Use this parameter to select one of the following values to specify the first Additional Party Category type. The configured value will be included inside the policy request message sent to the PSX and sent in the ISUP IAM message body of SIP-I/T or over GW-GW message.

  • Fixed_1-1
  • Fixed_1-2
  • Mobile_1-1
  • Mobile_1-2

 Additional Party Category Second

N/A

Use this parameter to select one of the above values to specify the second Additional Party Category type. The configured value will be included inside the policy request message sent to the PSX and sent in the ISUP IAM message body of SIP-I/T or over GW-GW message.
Calling Party Category InterworkingN/A

The flag Calling Party Category Interworking has two possible values:

  • Disabled (default)
  • Enabled

 To start Calling Party Category Interworking, set this flag to enabled. When set to enabled, the SBC populates the parameter Calling Party Category (CPC) with the value 11, on receiving the Resource Priority Header (RPH) in the initial INVITE. Here, the value 11 denotes "Calling Subscriber with priority". When RPH is absent in the initial INVITE, SBC populates the parameter CPC from the PAI Header.

History Info InterworkingN/A

The flag History Info Interworking has two possible values:

  • Disabled (default)
  • Enabled

 To start History Info Interworking, set this flag to enabled. When set to enabled, for the SIP-SIP-I call leg, the SBC maps History Info Header to ISUP Parameters (Original Called Number, Redirection Number, and Redirection Information). For the SIP-I-SIP call leg, the SBC maps the ISUP parameters in the MIME body to the corresponding History Info Header.

To summarize, when History Info Interworking is enabled, the SBC supports the following mappings:

  • History-Info to ISUP parameters (Redirecting Number, Original Called Number, and Redirection Information) for redirection, and the other way for the SIP-I-SIP call leg.
  • History-Info to ISUP parameters (Called IN Number and Original Called IN Number) for number translation, and the other way for the SIP-I-SIP call leg.
Enable PVCTTCParamsN/A

When disabled, the SBC deactivates the NNI PCV to trigger. The options are:

  • Disabled (default)
  • Enabled

Set Hi Presentation Restricted

N/A

The flag Set Hi Presentation Restricted has two possible values:

  • Disabled (default) – When disabled, the SBC sends send the Presentation as per privacy information it received.
  • Enabled – When enabled, the SBC sends the APRH (Address Presentation Restricted Indicator) as "Presentation Restricted" irrespective of privacy information in the History-Info (HI) header.

If privacy=history, Presentation should be Restricted 

 

If privacy=none or not present, Presentation should be allowed

Add User Equal Phonefor Div Hi Interworking

N/A

To start Add User Equal Phonefor Div Hi Interworking, set this flag to Enabled.

  • Disabled (default) – When disabled, the SBC will not add user=phone and mp parameter to history-info in Diversion-History-Info interworking.
  • Enabled – When enabled, the SBC sends user=phone and the mp parameter to history-info header, but only for Diversion-History-Info interworking.
Contractor Num InterworkingN/A

Enable this parameter to interwork the parameter Contractor Number to/from the ttc-charging-params information in the SIP header P-Charging-Vector.

  • Disabled (default)
  • Enabled

To Copy NNIProfile

To copy any of the created NNIProfile and to make any minor changes, click the radio button next to the specific NNI Profile in the NNI Profile List pane.

Click Copy NNIProfile tab on the NNIProfile List pane.

The Copy Selected NNIProfile window displays.
