What it does

When Diameter Rf charging is in use, the Rhino VoLTE TAS communicates with a CDF to deliver interim CDRs using Accounting Request (ACR) messages. If the communication with the CDF fails, ACR messages are held locally until it is restored.

Interim CDRs must be enabled to use Diameter Rf offline charging.

Configuration

The example for sentinel-volte-gsm-config.yaml and example for sentinel-volte-cdma-config.yaml show example configuration relevant to Diameter Rf offline charging in the sentinel-volte/charging/rf-charging section.

What you need

  • ❏ The release version of Diameter Rf to use with the offline charging system.

  • ❏ The origin realm to use when sending Diameter Rf messages. This is the TAS’s realm.

  • ❏ The destination realm to use when sending Diameter Rf messages. This is the offline charging system’s realm.

  • ❏ The CDF peers' hostnames, ports, and transport protocols.

Setting up Diameter Rf based offline charging

Use Diameter Rf offline charging

In the charging section, add an rf-charging section with:

        rf-charging:
            diameter-rf:
                diameter-rf-release: Vcb0
                origin-realm: metaswitch.com
                destination-realm: metaswitch.com
                destination-peers:
                    -   destination-hostname: peer.metaswitch.com
                        port: 3868
                        protocol-transport: sctp
                        metric: 1

You must ensure that all per-node-diameter-rf sections in the MMT cluster configuration are present and not commented out. The sections are located:

          # Remove this if diameter-rf is disabled
          per-node-diameter-rf:
              diameter-rf-origin-host: mmt1.mmt.site1.mnc123.mcc530.3gppnetwork.org
Disable Diameter Rf offline charging

In the charging section, remove or comment out the entire rf-charging section:

#        rf-charging:
#            diameter-rf:
#                diameter-rf-release: Vcb0
#                origin-realm: metaswitch.com
#                destination-realm: metaswitch.com
#                destination-peers:
#                    -   destination-hostname: peer.metaswitch.com
#                        port: 3868
#                        protocol-transport: sctp
#                        metric: 1

You must comment out any per-node-diameter-rf sections in the MMT cluster configuration, which are located:

          # Remove this if diameter-rf is disabled
#          per-node-diameter-rf:
#              diameter-rf-origin-host: mmt1.mmt.site1.mnc123.mcc530.3gppnetwork.org
