ASN Gateway Service Operation and Configuration
Access Service Network Gateway (ASN Gateway) provides wireless carriers with a flexible solution that supports both
Simple IP and Mobile IP applications, independently or simultaneously, within a single scalable platform. Simple IP and
Mobile IP applications are described in detail in the System Overview Guide.
Simple IP and Mobile IP applications, independently or simultaneously, within a single scalable platform. Simple IP and
Mobile IP applications are described in detail in the System Overview Guide.
To support Simple IP data applications, the system is configured to perform the role of an ASN Gateway within the
carrier’s WiMAX data network. The ASN Gateway provides IP access to mobile subscribers and routes data to and
from the Connectivity Service Network (CSN). The CSN may consist of Wireless Application Protocol (WAP) servers
or the Internet.

To support Mobile IP and/or Proxy Mobile IP data applications, the system is configured to perform the role of the ASN
Gateway/Foreign Agent (FA) and/or the Home Agent (HA) within the CSN of the carrier’s WiMAX data network.
When functioning as an HA, the ASN Gateway can be located within the carrier’s WiMAX network or in the CSN of an
external enterprise or ISP network. In either case, the ASN Gateway/FA terminates the mobile subscriber’s call session,
and then routes subscriber data to and from the appropriate HA.

Before you connect to the command line interface (CLI) and begin the system’s configuration, there are important
things to understand about how the system supports these applications. This chapter provides terminology and
background information to consider before you configure the system.
