- MNO hosts UPF/SPGW-U in their network.
- MNO provisions all UPF functions.
- MNO may request UPF Interconnection for SGi/N6 interface in a required Metro to 3PE/PCE via APIs (on P2)
- Bare Metal Orchestration Provider and Interconnect Provider expose Data Center Location / Metro to PCEI Enabler via APIs (on P3 and P4)
- 3PE and PCE providers expose Data Center Location / Metro to PCEI Enabler via APIs (on P5 and P8/P7)
- PCEI Enabler may request Bare Metal Orchestration for Distributed UPF via APIs (on P3)
- PCEI Enabler may request Interconnect for MNO UPF (L2/L3) via APIs (on P4)
- PCEI Enabler may request PCC/PCE and/or 3PE Controller to instantiate workload instances for LBO processing via APIs (on P8/P5)
UPF Placement Scenario
Assumptions:
- MNO supports CUPS (5G NSA) and/or UPF (5G SA).
- MNO may request UPF Placement / Metro, and 3PE/PCE Access / Metro, via APIs (on P2)
- Bare Metal Orchestration Provider and Interconnect Provider expose Data Center Location / Metro to PCEI Enabler via APIs (on P3 and P4)
- 3PE and PCE providers expose Data Center Location / Metro to PCEI Enabler via APIs (on P5 and P8/P7)
- PCEI Enabler may request Bare Metal Orchestration for Distributed UPF via APIs (on P3)
- PCEI Enabler may request Bare Metal Orchestration for 3PE via APIs (on P3)
- PCEI Enabler may request Interconnect for Distributed UPF N3/S1 and N6/SGi traffic (L2/L3) via APIs (on P4)
- PCEI Enabler may expose UPF management access to MNO
- MNO may provision the Distributed UPF over management access
- PCEI Enabler may provision UPF connectivity and LBO configuration (based on the UPF provisioning model) over P2’ using appropriate protocols
- PCEI Enabler may request PCC/PCE and/or 3PE Controller to instantiate workload instances for LBO processing via APIs (on P8/P5)
