1  ScopeWord‑p. 6

The present document specifies the Access Stratum (AS) part of the Idle Mode procedures applicable to a UE. The non-access stratum (NAS) part of Idle mode procedures and processes is specified in TS 23.122.
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 E-UTRA, including multi-RAT UEs as described in 3GPP specifications, in the following cases:
  • When the UE is camped on an E-UTRA cell;
  • When the UE is searching for a cell to camp on;
The Idle Mode procedures defined in this specification are also applicable for a UE in RRC_INACTIVE state unless specified otherwise.

3.1  Definitions

For 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. A UE can always attempt emergency calls on an acceptable cell, but restriction as in 5.3.3 apply.
Alternative cell reselection priority:

A list provided by NAS containing all the CSG identities and their associated PLMN IDs of the CSGs to which the subscriber belongs.
Available PLMN(s):
One or more PLMN(s) for which the UE has found at least one cell and read its PLMN identity(ies).
Barred Cell:
A cell a UE is not allowed to camp on.
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 Subscriber Group (CSG):
A Closed Subscriber Group identifies subscribers of an operator who are permitted to access one or more cells of the PLMN but which have restricted access (CSG cells).

Individual time interval between monitoring Paging Occasion for a specific UE.
eDRX cycle:
Time interval between the first Paging Occasions occurring after successive extended DRX periods.
