Section: 5.30.2.10.3 Onboarding Network is a PLMN
Content: 5.30.2.10.3.1 General A UE configured with PLMN credentials in USIM for primary authentication may register with a PLMN for the provisioning of SO-SNPN credentials. 5.30.2.10.3.2 Network selection and Registration This clause applies only when the UE is not in SNPN access mode. When the UE is using PLMN credentials for accessing a PLMN as the Onboarding Network (ONN), then regular network selection, as per TS 23.122[ Non-Access-Stratum (NAS) functions related to Mobile Station (MS) in idle mode ]  [17] and regular initial registration procedures apply, as per TS 23.502[ Procedures for the 5G System (5GS) ]  [3]. After successfully registering to the ON-PLMN, the UE is provisioned with the SO-SNPN credentials via User Plane as in clause 5.30.2.10.4.4. NOTE: When Onboarding network is a PLMN and the UE's subscription only allows for Remote Provisioning, then based on PLMN policies, the AMF can start an implementation specific timer once the UE has registered to the PLMN. Expiry of this timer triggers the AMF to deregister the UE from the PLMN. This specific timer is used to prevent registered UEs that are only allowed for Remote Provisioning from staying at the PLMN indefinitely.
