• MNO hosts UPF/SPGW-U in their network.
• MNO provisions all UPF functions.
• MNO may request Deployment of IoT Edge on Bare Metal or NFVi via APIs (on P2)
• PCEI Enabler IoT Edge Deployer may request HW or Virtual resources (e.g. VM/Container) (on P3)
• PCEI Enabler IoT Edge Deployer may provision IoT Edge (install runtime, deploy standard modules, register with IoT Hub) via APIs/Deployer Code (on P8/P5)
• PCEI Enabler may request Interconnect for IoT Edge between MNO and Azure (L2/L3) via APIs (on P4)
• PCEI Enabler may request UPF LBO for MNO to direct customer traffic to IoT Edge (on P2/P2’)
• PCEI Enabler may facilitate deployment of custom IoT Edge modules
