context: in the AMF generates the xIRI AMF RAN Handover Command record. The CC-POI in UPF + PGW-U does not generate the xCC for the UP packets from DL data forwarding tunnels (i.e. incoming at TEID (4c) and outgoing to TEID (4b). Likewise, the SGW does not generate the xCC for the UP packets from DL data forwarding tunnels (i.e. incoming at TEID (4b) and outgoing to TEID (4a). When the SMF + PGW-C sends the Nsmf_PDUSessionUpdateSMContext Response to the AMF with the updated SM context information, the IRI-POI present in the SMF generates the xIRI PDU Session Modification record. In this illustration, PFCP Session ID is used as the target identifier for the xCC generation in the CC-POI present in the UPF + PGW-U and therefore, the CC-POI in the UPF + PGW-U would generate the xCC from the packets received at TEID (1-1) without any additional trigger from the CC-TF present in SMF + PGW-C.

description: The PDN Gateway User Plane (PGW-U) is a network function responsible for handling user plane traffic in the Evolved Packet Core (EPC) and 5G networks. It plays a crucial role in routing and forwarding packets between the UE (User Equipment) and the external networks.
explanation: PGW-U is classified as a Network Function because it performs essential network operations like packet handling, routing, and forwarding within the EPC and 5G architectures.
