16.6.6 Support of UE onboarding and remote provisioning

An SNPN may offer support for restricted 3GPP connectivity for remote provisioning of credentials. The feature is enabled/disabled per cell.

The following information is broadcast to support UE onboarding and remote provisioning:

• an indication per onboarding SNPN in SIB1 that UE onboarding is enabled;
• optionally a list of supported GINs in SIB18 (each GIN may be assigned to one or more onboarding SNPNs).

The above listed items are forwarded to the UE NAS layer that uses them for onboarding SNPN selection. When a UE intends to perform onboarding, it sends the onboarding request indication to the gNB during RRC connection establishment.

The NG-RAN nodes receive information about onboarding support capabilities of the AMF(s). This information is used by the NG-RAN node to select a suitable AMF when receiving the onboarding request indication from the UE.
