Supported Inline Services 
All inline services described in this section require the appropriate feature license keys. 
 
Enhanced Charging Service 
The Enhanced Charging Service (ECS) is an in-line service feature integrated with the system. ECS provides flexible, 
differentiated, and detailed billing to subscribers by using Layer 3 through Layer 7 packet inspection. ECS can integrate 
with a back-end billing system. ECS functionality is supported at the point where sessions are anchored—for example, 
on the ASN Gateway for Simple IP sessions and on the home agent for Mobile IP sessions. 
For more information about ECS, refer to the Enhanced Charging Services Administration Guide. 
 
Multi-host Support 
ASN Gateway‘s multi-host feature provides multiple host connectivity. 
 
A WiMAX CPE modem supports multiple IP hosts in fixed/nomadic applications. The modem shares a single WiMAX 
airlink to connect to the WiMAX IP network. This feature is an effective solution for small or home office users to 
provide multiple station connectivity through one airlink.

The WiMAX ASN Gateway allows each WiMAX MS (identified by its 6-byte MSID) to be assigned a single IP 
address. IP accounting is maintained for the IP address.
