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

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
