Enhanced Charging Service Overview
Basic Features and Functionality ▀
Rulebase lists are created and configured in the ACS Configuration Mode. The maximum length of an individual
rulebase-list name is 64 bytes. The buffer that stores space-separated rulebase names within a rulebase-list is of 256
bytes.
In 12.3 and earlier releases, a maximum of 20 rulebase lists can be configured per active charging service.
In 14.0 and later releases, a maximum of 128 rulebase lists can be configured per active charging service.
When a subscriber call is connected, the Session Manager provides the list of rulebase names to the OCS, which
chooses the rulebase to be used for the subscriber session from the list.
In case the OCS is not reachable, the rulebase configured as the default will be used.
