Chapter 2 UE Idle Mode Behavior
2.1 Introduction
UE in idle mode behavior consists of following parts: PLMN selection: PLMN selection is to insure that the selected PLMN can provide
normal service. When an MS is switched on, it attempts to make contact with a public land mobile network (PLMN). The particular PLMN to be contacted may be selected either automatically or manually.
Cell selection and reselection: Cell selection and reselection is to find a suitable cell to camp on. If a suitable cell is found, the UE shall select this cell to camp on, and report this event to NAS so that the necessary NAS registration procedures can be performed. When the registration is successful, the UE enters in state Camped normally in order to obtain normal service. If the UE is unable to find any suitable cell of selected PLMN the UE shall enter the Any cell selection state.
Location registration (LR): Location registration (LR) includes location update and routing area update, which is used for non-GPRS and GPRS respectively.
Location update: The location updating procedure is a general procedure which is used for the purposes of normal location updating, periodic location updating and IMSI attach.
Routing area updating: The routing area updating procedure is a general procedure, which is used for purpose of normal routing area updating, combined routing area updating and periodic routing area updating.
Paging: Paging is used to transmit paging information to selected UEs in idle mode, CELL_PCH or URA_PCH state to establish a signaling connection or used to trigger a cell update procedure for UEs in CELL_PCH or URA_PCH state or to trigger UE reading updated system information. UTRAN may also initiate paging for UEs in CELL_PCH and URA_PCH state to release the RRC connection.
Receiving system information: System information is used to notify and control the behavior of UEs in a cell, which are broadcasted from the UTRAN by BCCH channel. System information is defined to different blocks with different characteristics named as MIB, SIB and SB and organized as a tree.

If the user does not select a PLMN, the selected PLMN shall be the one that was selected before the PLMN selection procedure started. If no such PLMN was selected or that PLMN is no longer available, then the MS shall attempt to camp on any acceptable cell and enter the limited service state.

III. Cell Reselection Criteria
rarchical cell re-selection rules
The following cell re-selection criteria are used for intra-frequency cells, inter-frequency cells and inter-RAT cells:
The quality level threshold criterion H for hierarchical cell structures is used to determine whether prioritized ranking according to hieshall apply, and is defined by:
Hs = Qmeas,s - Qhcss
Hn = Qmeas,n - Qhcsn – TOn * Ln
If it is indicated in system information that HCS is not used, the quality level threshold lied.
The cell-ranking criterion R is defined by:
criterion H is not app
The cell-ranking criterion R is defined by:
Rs = Qmeas,s + Qhysts
Rn = Qmeas,n - Qoffsets,n - TOn * (1 – Ln)
where:
TOn = TEMP_OFFSETn * W(PENALTY_TIMEn – Tn)
Ln = 0 if HCS_PRIOn = HCS_PRIOs
L = 1 if HCS_PRIO <> HCS_PRIO

TEMP_OFFSET applies an offset to the R criteria foPENALTY_TIMEn after a timer Tn has started for that neighbouring cell.
TEMP_OFFSETn and PENALTY_TIMEn are only applicable if the usage ofated in system information.
The UE shall perfo ranking of all cells that fulfil the S criterion among
all cells that have the highest HCS_PRIO among those cells that fulfil the criteriH >= 0. Note that this rule is not valid when UE high-mobility is detected.
all cells, not considering HCS priority levels, if no cell fulfil the criterion H >= This case is also valid when it is indicated in system information thused, that is when serving cell does not belong to a hierarchical cell structure.

The UE may use the scheduling information included within the master infoblock and the scheduling blocks to locate each system information block to be acq ired. If the UE receives a system information block in a position according to the scheduling information and consider the content valid, it will read and store it for future use. Below we will introduce the important IEs in each SIB in more detail.
System information block 1
UE should store all relevant IEs iirre pective of UE’s mode. The system information block type 1 contains NAS system

If in idle mode, the UE should store all relevant IEs included in this system information block if the "PLMN Type" in the variable SELECTED_PLMN has the value "GSM-MAP" and the IE "PLMN type" in the Master Information Block has the value "GSM-MAP" or "GSM-MAP and ANSI-41". The UE shall also:
