TIA TIA-873.014

This document addresses the Stage-3 protocol between an Access Gateway (AGW) and a Policy and Charging Rules Function (PCRF) in support of Service Based Bearer Control as described in [X.S0013-012]. The reference point between the AGW and the PCRF is designated as the Ty reference point and supports all cdma2000®1 radio technologies..

The protocol between the PCRF and the AGW enables the PCRF to dynamically control policy and charging behavior at the AGW. The protocol allows:

Interactions for the purpose of local authorization of bearer level QoS resources based on the resources negotiated at the application layer and/or based on local policy. In addition it supports the passing of information that may be used to establish flow based charging policy. Features of the protocol include the following: 1. Provision and removal of rules from the PCRF to the AGW;

2. Request for Policy and Charging Control (PCC) rules from the AGW to the PCRF;

3. Notification of bearer level events from the AGW to the PCRF;

4. Control of the flow of packets at the bearer level including the restriction of flow end-points (flow filtering); and

5. Support of general policy considerations for the allocation of resources on the bearer level in the local domain.
