Abstract

5G is getting widely deployed in industrial settings both in commercial and pricate networks due to its abilities of higher throughput, lower latency and massive connectivity support. But the integration of 5G with fixed industrial LAN is a challenge that needs to be dealt with. To deal with this integration issue, 3GPP developed an Ethernet PDU support feature that allows the passthrough of industrial ethernet traffic transparently over the mobile network. This thesis deploys and validates the end-to-end 5G system having Ethernet PDU support. The system integrates 5G User Equipment and a 5G Core network having Ethernet PDU Session support as defined in 3GPP Release 17 (TS 23.501) hence enabling efficient/seamless Ethernet transport over 5G networks. A key component is the User Plane Function (UPF), which acts as the PDU Session Anchor (PSA). The UPF supports Ethernet frame transport through specific configurations on the N6 interface, which connects the 5G Core to external networks. This thesis focuses on scenarios where each PDU Session corresponds to a single N6 interface, potentially forming a dedicated tunnel and allowing a point-to-point connection i.e. Eline support between UE and fixed end. This research demonstrates a tested and validated deployment of Ethernet PDU supported 5G network. The research will act as Proof of Concept for future work in this field as to provide a practical example of working Ethernet PDU testsetup for seamless l2 traffic over mobile networks. These insights are valuable for enterprise networking, industrial automation, and other applications that rely on L2 communication over mobile networks especially 5G.
