1 Title: TDF support in cdma2000 1x and HRPD Networks Sources: China Telecom, ZTE, Huawei Contact: CT: Heng Nie ( ), Congjie Mao( ) ZTE: Rajesh Bhalla Huawei: Jixing Liu Abstract: This proposal introduces the Traffic Detection Function (TDF) as supported by the 3GPP Rel-11 PCC, and highlights the requirements for supporting similar capabilities in the CDMA2000 1x and HRPD networks Recommendation: Discuss and adopt the associated Work Item Contributing companies grant a free, irrevocable license to 3GPP2 and its Organizational Partners to incorporate text or other copyrightable material contained in the contribution and any modifications thereof in the creation of 3GPP2 publications; to copyright and sell in Organizational Partner's name any Organizational Partner's standards publication even though it may include all or portions of this contribution; and at the Organizational Partner's sole discretion to permit others to reproduce in whole or in part such contribution or the resulting Organizational Partner's standards publication.

Background 2  PCC in cdma2000 specification (X.S0062 v1.0) allows the network to initiate QoS setup and allows the AF connected to the PCRF control over the QoS via the Gx interface, e.g., for IMS services  AF is not feasible for some applications, e.g.,VoD  3GPP has added TDF(Traffic Detection Function) in the PCC architecture Release 11  TDF allows the detection of application specific traffic and bandwidth guarantees, traffic gating and bandwidth limitations for the detected traffic  TDF can be a standalone function or built-in within the PCEF

Traffic Detection Function in CDMA2000 [1]  TDF detects application specific traffic for non-IMS services  On instructions from the PCRF  Via pre-configured rules at the TDF  On indications from the AAA through authentication and authorization procedures  Reports detected application specific traffic to the PCRF  The PCRF could then initiate policy control for such application specific traffic  Performs bandwidth guarantee, traffic gating or bandwidth limitations for the detected application specific traffic  By means of dynamic control from the PCRF  By means of operator pre-configured policy 3

 Allows changes to BE flow QoS parameters (priority, bandwidth)  On instructions from the AAA  On instructions from the PCRF  Performs usage monitoring for the accumulated usage of network resources related to the TDF applications or for all BE flows  On instructions from the PCRF  Via pre-configured rules at the TDF  Via indications from the AAA through authentication procedure  Reports usage monitoring results to the PCRF or to the AAA  Reporting to the AAA could be done via interim charging records 4 Traffic Detection Function in CDMA2000 [2]
