Gw and Gwn reference point for sponsored data connectivity
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 3GPP TS 23.203 [2]. 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).
