This paper presents the architectural considerations of in- tegrating the non-IP-based service routing solution, Name- based Routing, to the 5G user plane. While entirely pre- serving the control plane procedures on the terminal, the carefully crafted out considerations argue for a new Session Management Function functionality and the transitioning of N4 to Nupf. Furthermore, this paper presents User Plane Function provisioning procedures based on Software-defined Networking principles mitigating the need for any manual management procedures and enabling a cloud native or- chestration of all 5G Core Network Functions. A planned multi-vendor 5G Core trial is described demonstrating the benefits of a service routing-enabled 5G user plane.
