SIB18 (SIB18-r17)
SIB18-r17 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
SIB18 contains Group IDs for Network selection (GINs) to support access using credentials from a Credentials Holder or to support UE onboarding.

| Field | Description |
|---|---|
| gin-ElementList-r17 SEQUENCE (SIZE (1..maxGIN-r17)) OF GIN-Element-r17 · OPTIONAL Need R | The gin-ElementList contains one or more GIN elements. Each GIN element contains either one GIN, which is identified by a PLMN ID and a NID, or multiple GINs that share the same PLMN ID. The total number of GINs indicated does not exceed maxGIN-r17. The GIN index m is defined as d1+d2+…+d(n-1)+i for the GIN included in the n -th entry of the gin-ElementList and the i -th entry of its corresponding GIN-Element , where d(k) is the number of GIN index values used in the k -th gin-ElementList entry. |
| gins-PerSNPN-List-r17 SEQUENCE (SIZE (1..maxNPN-r16)) OF GINs-PerSNPN-r17 · OPTIONAL Need S since v17.1.0 | Indicates the supported GINs for each SNPN. The network includes the same number of entries as the number of SNPNs in snpn-AccessInfoList in provided in SIB1, and the n-th entry in this list corresponds to the n-th SNPN listed in snpn-AccessInfoList provided in SIB1. The network configures this field only if the cell broadcasts more than one SNPN in SIB1 . If this field is absent, as in case of a single SNPN broadcasted in SIB1 , the UE shall associate all GINs in gin-ElementList to that SNPN. |
