Figure P.1-1 shows the logical PIN reference architecture.
A Personal IoT Network (PIN) in 5GC consists of one or more devices providing gateway/routing functionality known as the PIN Element with Gateway Capability (PEGC), and one or more devices providing PIN management functionality known as the PIN Element with Management Capability (PEMC) to manage the Personal IoT Network; and device(s) called the PIN Elements (PINE). A PINE can be a non-3GPP device.
The PIN can also have a PIN Application Server that includes an AF functionality. The AF can be deployed by mobile operator or by an authorized third party. When the AF is deployed by third party, the interworking with 5GS is performed via the NEF.
The PEMC and PEGC communicates with the PIN Application Server at the application layer over the user plane. The PEGC and PEMC can communicate with each other via direct communication using 3GPP access (e.g. PC5) or non-3GPP access (e.g. WiFi, BT) or via a PDU Session in the 5GS.
