IP Services Gateway Overview

In-line Services

As described previously, the IPSG provides a method of inspecting RADIUS packets to discover user identity for the
purpose of applying enhanced services to the subsequent data flow. Internal applications such as the Enhanced Charging
Service, Content Filtering, and Application Detection and Control are primary features that take advantage of the IPSG
service.

Application Detection and Control

Application Detection and Control (ADC) is an in-line service feature that detects peer-to-peer protocols in real time
and applies actions such as permitting, blocking, charging, bandwidth control, and TOS marking.
For more information, refer to the Application Detection and Control Administration Guide.

Content Filtering

Content Filtering is an in-line service feature that filters HTTP and WAP requests from mobile subscribers based on the
URLs in the requests. This enables operators to filter and control the content that an individual subscriber can access, so
that subscribers are inadvertently not exposed to universally unacceptable content and/or content inappropriate as per
the subscribers' preferences.
For more information, refer to the Content Filtering Services Administration Guide.

Enhanced Charging Service

Enhanced Charging Service (ECS)/Active Charging Service (ACS) is the primary vehicle performing packet inspection
and applying rules to the session which includes the delivery of enhanced services.
For more information, refer to the Enhanced Charging Service Administration Guide.
