Network Deployment Configurations

This section provides examples of how the system can be deployed within a wireless carrier's network. As noted

previously in this chapter, the system can be deployed in standalone configurations, serving as a Home Agent (HA) and

a Packet Data Serving Node/Foreign Agent (PDSN/FA), or in a combined PDSN/FA/HA configuration providing all

services from a single chassis.

Standalone PDSN/FA and HA Deployments

The following figure depicts a sample network configuration wherein the HA and the PDSN/FA are separate systems.

The HA allows mobile nodes to be reached, or served, by their home network through its home address even when the

mobile node is not attached to its home network. The HA performs this function through interaction with an FA that the

mobile node is communicating with using the Mobile IP protocol. Such transactions are performed through the use of

virtual private networks that create Mobile IP tunnels between the HA and FA.

Interface Descriptions

This section describes the primary interfaces used in a CDMA2000 wireless data network deployment.

Pi Interfaces

The Pi interface provides connectivity between the HA and its corresponding FA. The Pi interface is used to establish a

Mobile IP tunnels between the PDSN/FA and HA.
