User Plane Function Distribution and Local Break-Out

UPF Distribution/Shunting capability -- distributing User Plane Functions in appropriate Data Center Facilities on qualified compute hardware for routing the traffic to desired applications and network/processing functions/applications.
Local Break-Out (LBO) – Examples: video traffic offload, low latency services, roaming optimization.

Assumptions:

MNO supports CUPS (5G NSA) and/or UPF (5G SA).
MNO can request UPF Location / Metro and 3PE/PCE Location / 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 can request Bare Metal Orchestration for Distributed UPF via APIs (on P3)
PCEI Enabler can request Interconnect for Distributed UPF (L2/L3) via APIs (on P4)
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)

Location Services -- location of a specific UE, or identification of UEs within a geographical area, facilitation of server-side application workload distribution based on UE and infrastructure resource location.

Assumptions:

MNO provides a Location Service (LS) compliant with OMA Zonal Presence API (OMA-TS-REST_NetAPI_ZonalPresence)
MNO may expose the Location Service via the Network Exposure Function (NEF)
A Public Cloud Edge (PCE) instance is associated with a Zone (collection of Access Points such as small cells) provided by an MNO
A 3rd-Party Edge (3PE) instance is associated with a Zone (collection of Access Points such as small cells) provided by an MNO
An application/workload in the PCE requires Location Information (e.g. coordinates of the Access Point) for the UE/subscriber
An application/workload in the 3PE requires Location Information (e.g. coordinates of the Access Point) for the UE/subscriber
PCEI Enabler facilitates Zonal Presence API Request/Response routing between PCE and the MNO LS and between the 3PE and the MNO LS
