ECS enables the collection of counters for different types of data traffic, and including that data in CDRs that is sent to a
Charging Gateway Function (CGF).
For more information on GTPP accounting, if you are using StarOS 12.3 or an earlier release, refer to the AAA and
GTPP Interface Administration and Reference. If you are using StarOS 14.0 or a later release, refer to the GTPP

RADIUS Accounting and Credit Control

The Remote Authentication Dial-In User Service (RADIUS) interface in ECS is used for the following purposes:
 Subscriber Category Request—ECS obtains the subscriber category from the AAA server (either prepaid or
postpaid) when a new data session is detected. The AAA server used for the subscriber category request can be
different from the AAA server used for service authorization and accounting.
 Service Access Authorization—ECS requests access authorization for a specific subscriber and a newly
detected data session. The AAA server is the access Policy Decision Point and the ECS the Policy Enforcement
Point.
