14、in version number as follows:Version x.y.zwhere:x the first digit:1 presented to TSG for information;2 presented to TSG for approval;3 or greater indicates TSG approved document under change control.y the second digit is incremented for all changes of substance, i.e. technical enhancements, correcti

15、ons, updates, etc.z the third digit is incremented when editorial only changes have been incorporated in the document.1 ScopeThe present document specifies the Access Stratum (AS) part of the UE procedures in RRC_IDLE state (also called Idle mode) and RRC_INACTIVE state. The non-access stratum (NAS)

16、 part of Idle mode procedures and processes is specified in 9.The present document specifies the model for the functional division between the NAS and AS in a UE.The present document applies to all UEs that support at least NR Radio Access, including multi-RAT UEs as described in 3GPP specifications

17、, in the following cases:- When the UE is camped on a NR cell;- When the UE is searching for a cell to camp on;NOTE: When the UE is camped on or searching for a cell to camp on belonging to other RATs, the UE behaviour is described in the specifications of the other RATs.2 ReferencesThe following do

23、or the purposes of the present document, the following terms and definitions apply:Acceptable Cell: A cell that satisfies certain conditions as specified in 4.3. Available PLMN(s): One or more PLMN(s) for which the UE has found at least one cell and read its PLMN identity(ies).Camped on a cell: UE h

24、as 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.Com

25、mercial Mobile Alert System: Public Warning System that delivers Warning Notifications provided by Warning Notification Providers to CMAS capable UEs.Home PLMN: 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.P

26、rocess: 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.Registration Area: (NAS) registration area is an area in which the UE may roam without a need to pe

27、rform location registration, which is a NAS procedure.Selected PLMN: This is the PLMN that has been selected by the NAS, either manually or automatically.Serving cell: The cell on which the UE is camped.Strongest cell: The cell on a particular carrier that is considered strongest according to the la

28、yer 1 cell search procedure 4, 5.Suitable Cell: This is a cell on which a UE may camp. For NR cell, the criteria are defined in subclause 4.3, for E-UTRA cell in 7.3.2 AbbreviationsFor the purposes of the present document, the abbreviations given in 3GPP TR21.905 1 and the following apply.

RNA update is only applicable for RRC_INACTIVE state.When a UE is switched on
