▀ Features and Functionality - Base Software
Event Detail Records (EDRs)
Usage Detail Records (UDRs)
ECS provides for the generation of charging data files, which can be periodically retrieved from the system and used as
input to a billing mediation system for post-processing. These files are provided in a standard format, so that the impact
on the existing billing/mediation system is minimal and at the same time, these records contain all the information
required for billing based on the content.
GTPP accounting in ECS allows the collection of counters for different types of data traffic into detail records. The
following types of detail records are supported:
Event Detail Records (EDRs): An alternative to standard G-CDRs when the information provided by the G-
CDRs is not sufficient to do the content billing. EDRs are generated according to explicit action statements in
rule commands that are user-configurable. The EDRs are generated in comma separated values (CSV) format,
generated as defined in traffic analysis rules.
User Detail Records (UDRs): Contain accounting information related to a specific mobile subscriber. The fields
to be reported in them are user-configurable and are generated on any trigger of time threshold, volume
threshold, handoffs, and call termination. The UDRs are generated in comma separated values (CSV) format,
generated as defined in traffic analysis rules.
Important:
use license. For more information on ECS, refer to the Enhanced Charging Service Administration Guide.
Diameter Credit Control Application
Provides a pre-paid billing mechanism for real-time cost and credit control based on the following standards:
RFC 3588, Diameter Base Protocol, September 2003
RFC 4006, Diameter Credit-Control Application, August 2005
The Diameter Credit Control Application (DCCA) is used to implement real-time credit-control for a variety of end user
services such as network access, Session Initiation Protocol (SIP) services, messaging services, download services etc.
Used in conjunction with ECS, the DCCA interface uses a mechanism to allow the user to be informed of the charges to
be levied for a requested service. In addition, there are services such as gaming and advertising that may credit as well
as debit from a user account.
DCCA also supports the following:
Real-time Rate Service Information: The ability to verify when end subscribers' accounts are exhausted or
expired; or deny additional chargeable events.
Support for Multiple Services: The usage of multiple services within one subscriber session is supported.
Multiple Service support includes:
