name: PDN-GW
full_form: PDN Gateway
context: Interception in the PDN-GW is a national option. However, in certain scenarios the PDN-GW is the only ICE in the 3GPP network where interception in the PLMN accessed by the target can be performed (i.e., for trusted non-3GPP access, the HPLMN in case of non roaming and the VPLMN in case of roaming with local breakout). As a national option, in the case where the PDN-GW is reporting IRI for a target, the target is handed off to another S-GW and the same PDN-GW continues to handle the content of communications subject to roaming agreements, the PDN-GW shall continue to report the IRIs. NOTE: In some situation (e.g. during activation of second, third, etc, intercepts on the target), the MF/DF may have to detect on its own that an interception is activated on a target with active bearer or with active PMIP/MIP/DSMIP tunnel.
description: The PDN Gateway (PDN-GW) manages the connection between the Evolved Packet Core (EPC) and external packet data networks. It handles IP address allocation, policy enforcement, and charging.
explanation: The text describes the PDN-GW as a component responsible for managing network connections and performing functions like IP address allocation and policy enforcement. This aligns with the definition of a Network Function, which is a software or hardware element that provides specific telecommunications capabilities within a network.
