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

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

Purpose

The purpose of this document is to provide the standard for interfacing a PCF with one or more BSs.
