Accounting Interfaces
ECS supports different accounting and charging interfaces for prepaid and postpaid charging and record generation.
Important:
Some feature supports described in this section are license enabled. If you have not previously
purchased licenses for these services, contact your sales representative for more information.
GTPP Accounting
Important:
GTPP Accounting is only available for GGSN networks.
GTTP accounting in ECS allows the collection of counters for different types of data traffic, and including that data in a
G-CDR that is sent to a Charging Gateway Function (CGF).
Standard G-CDRs do not have an attribute which defines traffic counters depending upon the traffic type but they do
have a field named ―Record Extensions‖ where all vendor-specific information can be included. ECS includes the
counters for different types of data traffic in this field when sending a G-CDR.
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.
On-line Service Accounting (Prepaid) : ECS reports service usage to the AAA server. The AAA server acts as
a prepaid control point and the ECS as the client. Accounting can be applied to a full prepaid implementation
or just to keep ECS updated of the balance level and trigger a redirection if the subscriber balance reaches a
low level.
