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 Peer-to-Peer Detection are primary features that take advantage of the IPSG service.
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 .
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 .
Peer-to-Peer
Peer-to-Peer 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 Peer-to-Peer Detection Administration Guide .
