Content for TS 29.251 Word version: 18.0.0
1 Scope p. 6
The present document provides the stage 3 specification of the Gw and Gwn reference points. The functional requirements and the stage 2 specifications of the Gw and Gwn reference points are specified in TS 23.203. The Gw reference point lies between the Packet Flow Description Function (PFDF) and the Policy and Charging Enforcement Function (PCEF). The Gwn reference point lies between the Packet Flow Description Function (PFDF) and the Traffic Detection Function (TDF).

3 Definitions and abbreviations p. 7
3.1 Definitions p. 7
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Packet Flow Description (PFD):
A set of information enabling the detection of application traffic provided by a 3rd party service provider (from TS 23.203).
Pull mode:
A mode used between the PCEF/TDF and the PFDF where the PFDs are sent by the PFDF at reception of an HTTP request from the PCEF/TDF.
Push mode:
A mode used between the PCEF/TDF and the PFDF where the PFDs and/or notification of PFD deletion are sent by the PFDF in an HTTP request to the PCEF/TDF.
Combination mode:
A mode used between the PCEF/TDF and the PFDF where both pull and push exist. This mode allows the PFDF to send the PFDs at reception of an HTTP request from the PCEF/TDF and provision PFD changes (creation/update/deletion) and/or notification of PFD creation/update/deletion in the HTTP request to the PCEF/TDF.
3.2 Abbreviations p. 7
