full_form: PIN Service Provider
context: Figure 6.4.2-1 shows the procedure for authentication of a PINE. Figure 6.4.2-1: Authentication procedure for PINE using DN specific secondary authentication PINE acts as an EAP client, SMF acts as an EAP Authenticator and PSP DN-AAA server acts as an EAP server. The individual steps are described below. PINE requesting connectivity via PEGC/UE: Step 1a. When a PINE wants to connect to the PSP (PIN application Service Provider) Data Network, PINE request for connection towards PEGC/UE. Step 1b. If the PEGC/UE is not yet registered with the 5GS, it performs primary authentication using PEGC/UE USIM credentials. Step 1c. The PEGC/UE request for PDU session establishment towards the PSP DN via 5GS. Step 1d. The SMF obtains the subscription information from the UDM and verifies if the PEGC/UE request for PSP DN is allowed or not. Step 1e. If the PEGC/UE is allowed to connect to the requested PSP DN, then SMF initiates the EAP authentication. Secondary Authentication between PINE and PSP
description: The PIN Service Provider (PSP) is a network function that provides PIN application services to user equipment (UE). It acts as an EAP server in the secondary authentication procedure for PINE, interacting with the SMF and PEGC/UE to authenticate and authorize access to its data network.
explanation: The context describes PSP as an entity involved in the authentication and authorization process of a PINE, specifically acting as an EAP server. This role is characteristic of a Network Function within the 3GPP specification.
