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.
UNRESOLVABLE BXREF: call-data-records#interim-cdrs[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
I want to…
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-
The
diameter-rf-releaseto use. -
The Diameter
origin-realmfor the Rhino VoLTE TAS. -
The Diameter
destination-realmfor the offline charging system. -
A Diameter
destination-peerslist that correspond to CDF servers. There must be at least one entry, and for each entry the following values must be set:-
the
destination-hostnamefor the CDF -
the
portfor the CDF -
the
protocol-transportto use with the CDF. -
the
metricto use for this CDF peer.
-
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:
-
for GSM deployments, in
mmt-gsm-vmpool-config.yaml -
for CDMA deployments, in
mmt-cdma-vmpool-config.yaml
# Remove this if diameter-rf is disabled
per-node-diameter-rf:

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

-
for GSM deployments, in
mmt-gsm-vmpool-config.yaml -
for CDMA deployments, in
mmt-cdma-vmpool-config.yaml
