For the purposes of the present document, the following terms and definitions apply:
Allowed CAG list:
A cell that satisfies certain conditions as specified in clause 4.5
A per-PLMN list of CAG Identifiers the UE is allowed to access (see TS 23.501
One or more PLMN(s) for which the UE has found at least one cell and read its PLMN identity(ies).
A cell a UE is not allowed to camp on.
A cell broadcasting at least one Closed Access Group Identifier.
Camped on a cell:
UE has completed the cell selection/reselection process and has chosen a cell. The UE monitors system information and (in most cases) paging information.
Camped on any cell:
UE is in idle mode and has completed the cell selection/reselection process and has chosen a cell irrespective of PLMN identity.
Closed Access Group Identifier:
Identifier of a CAG within a PLMN.
Commercial Mobile Alert System:
Public Warning System that delivers Warning Notifications provided by Warning Notification Providers to CMAS capable UEs.
eCall Only Mode:
A UE configuration option that allows the UE to register at 5GC and register in IMS to perform only eCall Over IMS, and a non-emergency IMS call for test and/or terminal reconfiguration services.
Equivalent PLMN list:
Any of the PLMN entries contained in the Equivalent HPLMN list TS 23.122
List of PLMNs considered as equivalent by the UE for cell selection, cell reselection, and handover according to the information provided by the NAS.
A PLMN where the Mobile Country Code (MCC) and Mobile Network Code (MNC) of the PLMN identity are the same as the MCC and MNC of the IMSI.
Identifier of an SNPN in combination with a PLMN ID (TS 23.501
NR sidelink communication:
A network deployed for non-public use, as defined in TS 22.261
AS functionality enabling at least V2X Communication as defined in TS 23.287
, between two or more nearby UEs, using NR technology but not traversing any network node.
A local action in the UE invoked by an RRC procedure or an RRC_IDLE or RRC_INACTIVE state procedure.
Radio Access Technology:
Type of technology used for radio access, for instance NR or E-UTRA.
(NAS) registration area is an area in which the UE may roam without a need to perform location registration, which is a NAS procedure.
This is the PLMN on which certain Location Registration outcomes have occurred, as specified in TS 23.122
This is the SNPN on which certain Location Registration outcomes have occurred, as specified in TS 23.122
A cell on which camping is not allowed, except for particular UEs, if so indicated in the system information.
This is the PLMN that has been selected by the NAS, either manually or automatically.
This is the SNPN that has been selected by the NAS, either manually or automatically.
The cell on which the UE is camped.
SNPN Access Mode:
UE to UE interface for V2X sidelink communication defined in TS 23.287
Mode of operation wherein UE only selects SNPNs (as defined in TS 23.501
An identifier of an SNPN comprising of a PLMN ID and an NID combination.
The cell on a particular frequency that is considered strongest according to the layer 1 cell search procedure (TS 38.213
, TS 38.215
V2X sidelink communication:
This is a cell on which a UE may camp. For NR cell, the criteria are defined in clause 4.5
, for E-UTRA cell in TS 36.304
AS functionality enabling V2X Communication as defined in TS 23.285
, between nearby UEs, using E-UTRA technology but not traversing any network node.
