APN Configuration Mode Commands
▀ credit-control-group
▄ Command Line Interface Reference, StarOS Release 18
1328
Important:
The CLI command “
cc-sgsn
” within APN configuration mode, should be used cautiously as this
will cause the charging-chars to be altered/modified.
Usage
Use this command to configure the credit control group for this APN.
Creating different credit control groups enables applying different credit control configurations (DCCA
dictionary, failure-handling, session-failover, Diameter endpoint selection, etc.) to different subscribers on the
same system.
Without credit control groups, only one credit control configuration is possible on a system. All the
subscribers in the system will have to use the same configuration.
In releases prior to 16, only one credit-control-group can be specified inside an APN. In 16 and later releases,
the APN configuration is extended to include the Charging-Characteristic (CC) preference for the credit-
control-group. This APN configuration is also extended to allow configuring additional credit-control-groups
for each of the CC values. With this enhancement, the OCS selection can be done based on the CC value
received via GTP request.
When the local authentication (session-setup-request) is done, the credit-control-group with the matching
charging-characteristic will be selected, and used. If there is no matching charging-characteristic
configuration found for the credit-control-group selection, then the default credit-control-group for the APN
will be selected.
The CC based OCS selection feature is applicable only for the Charging-Chars value received via GTP-Auth-
Request, and during the session-establishment. The Charging-Chars value updated via AAA/PCRF after the
session setup will not cause any change in already selected "credit-control-group". Once the credit-control-
group is selected (after session setup), this feature is not applicable.
APN configuration information is stored in AAA manager. Credit control group information from the APN
configuration is filled during the session-authentication time, by AAA manager. So, AAA manager should be
informed of the Charging-Characteristic value received at the time of Session-Authentication, so that the
desired credit-control-group can be selected.
Thus, the operator has the added flexibility to choose different OCS charging servers based on their business
logic. This could help multi-national operators to choose correct OCS servers based on countries for roaming
subscribers.

Example
The following command configures a credit control group named
testgroup12
for the current APN:
credit-control-group testgroup12
