Section: 5.39 Remote provisioning of credentials for NSSAA or secondary authentication/authorization 5.39.1 General
Content: The UE's subscribed network (i.e. HPLMN, or subscribed SNPN) may provide functionalities to provision or update the credentials used for NSSAA or credentials used for secondary authentication/authorization to the UE. The provisioning procedure is supported via User Plane. For User Plane Remote Provisioning, the UE establishes a PDU Session that is used for remote provisioning, e.g. by using DNN(s)/S-NSSAI(s) which can access the PVS. The AMF selects an SMF used for remote provisioning using the SMF discovery and selection functionality as described in clause 6.3.2. If the SMF is configured with the PVS address(es) and/or PVS FQDN(s), the SMF shall send the PVS address(es) and/or PVS FQDN(s) per DNN/S-NSSAI to the UE via PCO during PDU Session Establishment procedure, based on the UE's subscribed DNN(s)/S-NSSAI(s) and the UE's request of PVS information from the network. Alternatively, the UE may be configured with an address of a PVS or the PVS may subscribe for UE Reachability Notification and may use the Application Triggering procedure as specified in TS 23.502[ Procedures for the 5G System (5GS) ]  [3] to trigger the UE to initiate the setup of a connection for remote provisioning.
