This standard provides the specification for the interface that coincides with the Reference Point "Aquater" defined in the 3GPP2 Wireless Network Reference Model shown in [I-1]. The scope of this standard includes the following topics:

• Descriptions of the specified functional capabilities that provide packet data services across the PCF-PDSN interface;

• Descriptions of the division of responsibility of the functions provided between the PCF and the PDSN without prescribing specific implementations.

Purpose

The purpose of this document is to provide the standard for interfacing one or more PDSNs with one or more PCFs. This document defines the functional capabilities, including services and features, of the specified interfaces. These services and features are the defining characteristics that are the basis for the overall system standard.
