Introduction
The IP Services Gateway (IPSG) is a stand-alone device capable of providing managed services to IP flows. The IPSG
is situated on the network side of legacy, non-service capable GGSNs, PDSNs, HAs, and other subscriber management
devices. The IPSG can provide per-subscriber services such as enhanced charging, stateful firewall, traffic performance
optimization, and others.
The IPSG allows the carrier to roll out advanced services without requiring a replacement of the HA, PDSN, GGSN, or
other access gateways and eliminates the need to add multiple servers to support additional services.
Important: The IPSG is a license-dependent feature.
