name: PDG
full_form: Packet Data Gateway
context: settlements. NOTE 1: Per tunnel accounting generation in the WAG is not required when the WAG and PDG are in the same network. Packet Data Gateway: the Packet Data Gateway (PDG) applies to a WLAN 3GPP IP Access enabled system. 3GPP PS based services are accessed via a PDG in the user's Home Network or a PDG in the selected VPLMN. 3GPP PS based services may be accessed via a PDG in the user's HPLMN or a PDG in the selected VPLMN. From charging point of view the Packet Data Gateway: generates charging information related to user data traffic for offline and online charging purposes; may apply IP flow based bearer level charging, e.g. in order to differentiate or suppress WLAN bearer charging for 3GPP PS based services. Editor's Note: PDG functionality may be provided by re-using the existing GGSN functionality. The current working assumption is that the TPF is a logical function allocated to the PDG providing IP flow based bearer level charging capabilities. Following is a functional
description: The Packet Data Gateway (PDG) manages packet data traffic in a WLAN 3GPP IP Access enabled system. It generates charging information for both offline and online charging purposes, and applies IP flow based bearer level charging.
explanation: The text describes the PDG as a component responsible for managing data traffic, generating charging information, and applying charging policies. These functions are characteristic of a Network Function within a telecommunications system.
