2OverviewThe UE enters the idle mode immediately after being switched on. The feature UE Behaviors

in Idle Mode feature ensures that the UE is ready to start a service (for example, to make a call

or pick a call).

The behaviors are as follows:

l PLMN selection

This procedure ensures that the PLMN selected by the UE provides services properly.

l Cell selection and reselection

This procedure ensures that the UE finds a suitable cell to camp on.

l Location registration

This procedure is used by the UE to report its status to the network. This procedure is oftwo types: periodical location registration and the location registration necessitated by

changes in the location area.

In addition, the UE in idle mode takes the following actions:

l Paging reception

The network sends paging messages to the UE in CELL_PCH or URA_PCH state.

The UE detects the paging indicator on the PICH within the predefined time and receives

corresponding paging messages on the S_CCPCH. If the cell and the UE in CELL_FACH

support the HS-DSCH function, UE in CELL_PCH or URA_PCH state receives paging

messages on the HS-PDSCH.l Broadcast information reception

The network broadcasts the network information to the UE that camps on the cell. Upon

receipt of broadcast information, the UE obtains the network information and takes actions

accordingly.

This feature enables the UE to:

l Receive system information from the PLMN

l Prepare to establish the RRC connection

l Prepare to respond to paging messages

l Receive cell broadcast services

3PLMN Selection

3.1 Overview

When the UE is switched on, or the coverage is restored, or the UE selects a cell that belongs to

another PLMN, the UE selects the registered PLMN or its equivalent PLMN. If no registered

PLMN or equivalent PLMN is available, or if registration fails, the UE performs one of the

following two procedures, depending on its operating mode:

l Automatic selection

The UE automatically selects a PLMN according to the priority order.

l Manual selection

The UE shows all available PLMNs to the subscriber. The subscriber then selects a PLMN.

For more details of the PLMN selection, refer to section 5.1 "PLMN selection" in 3GPP TS

25.304 V10.0.0 and section 4.4 "PLMN selection process" in 3GPP TS 23.122 V10.0.0.

3.2 PLMN Selection Procedure

The PLMN selection procedure in automatic selection mode and manual selection mode is the

same. Following is the procedure:

lThe UE selects the target PLMN based on the following rule:The UE selects the EHPLMN with the highest priority if it is available; otherwise, the UE

selects the HPLMN.

l The UE selects the combination of PLMN with radio access technology (RAT) in the

following order:

1. Each combination of PLMN with RAT in the "User Controlled PLMN Selector with

Access Technology" data file in the USIM, in order of priority.

Combinations of PLMNs with RATs are saved in the data file in order of priority.

2. Each combination of PLMN with RAT in the "Operator Controlled PLMN Selector

with Access Technology" data file in the USIM, in order of priority.

Combinations of PLMNs with RATs are saved in the data file in order of priority.

14/230

3. Other combinations of PLMNs with RATs providing high quality signals, in a random

order.

4. Other combinations of PLMNs with RATs in order of decreasing cell signal quality.

The HPLMN are the PLMNs of which the MCC and MNC are the same as that in the IMSI of

the UE. The HPLMNs are the network that the UE subscribed.

The VPLMNs are the PLMNs that the UE camps on except the HPLMNs.

3.3 Roaming in the VPLMN

If a UE stays in a VPLMN, it periodically searches for the HPLMN and higher-priority PLMNs

for better services.

For this purpose, a value of T minutes may be stored in the SIM. Either T is in the range 6 minutes

to 8 hours with a step of 6 minutes or T indicates that no periodic attempts shall be made. If no

value is stored in the SIM, a default value of 60 minutes is used.

When the UE attempts to access the HPLMN or the PLMN with higher priority, the UE must

adhere to the following rules:

l After the UE is switched on, a period of at least two minutes and at most T minutes shall

elapse before the first attempt is made.

l Periodic attempts shall be performed only by the UE in idle mode.

l Only the priority levels of equivalent PLMNs of the same country (which serve as the

current serving VPLMN) can be compared with the priority level of a selected PLMN.

4Cell Selection and ReselectionAfter the PLMN is selected, the UE starts to select a suitable cell that belongs to the selected

PLMN to camp on and to resume normal services. For details, see section 5.2 "Cell selection

and reselection in idle mode" in 3GPP TS 25.304 V10.0.0.

Table 4-1describes the UE state involved in the cell selection.

Table 4-1UE state involved in the cell selection

SN State Description

1 Camped

normally

The UE camped on a suitable cell.

A "suitable cell" is a cell on which the UE may camp on to obtain

normal service.

2 Connected mode After RRC connection setup, the UE changes from the idle mode

to the connected mode (CELL_DCH, CELL_FACH,

CELL_PCH, or URA_PCH state)

3 Any cell

selection

The UE attempts to find an acceptable cell of any PLMN to camp

on.

An "acceptable cell" is a cell on which the UE may camp to obtainlimited service (originate emergency calls).

4 Camped on any

cell

The UE obtains limited services and selects a cell through cell

selection or reselection. In this case, the PLMN identity is not

considered.

Figure 4-1also shows the following items:

l Initial cell selection

If no cell information is stored for the PLMN, the UE starts the initial cell selection. For

this procedure, the UE need not know in advance which Radio Frequency (RF) channels

are UTRA carriers. The UE scans all RF channels in the UTRA band according to its

capabilities to find a suitable cell of the selected PLMN.

On eachcarrier, The UE searches for the cell with the best signal quality. Once a suitable

cell is found, this cell shall be selected.

l Stored information of cell selection

For this procedure, The UE has to know the central frequency information and other

optional cell parameters that are obtained from the measurement control information

received before, such as scrambling codes.

After this procedure is started, the UE selects a suitable cell if any. Otherwise, the initial

cell selection procedure is triggered.

l Cell selection of the UE leaving the connected mode

When returning to the idle mode from the connected mode, the UE shall select a suitable

cell to camp on. Candidate cells for this selection are the cells used immediately before the

UE leaves the connected mode.

When returning to the idle mode after an emergency call on any PLMN, the UE shall select

an acceptable cell to camp on. Candidate cells for this selection are the cells used

immediately before the UE leaves the connected mode.

If no acceptable cell is found, the UE shall continue to search for an acceptable cell on any

PLMN in the state "Any cell selection".

UL TX power.

l MaxUEPower: maximum RF output power of the UE (dBm)

MaxAllowedUlTxPower(BSC6900,BSC6910)is set by the network

according to the designed cell coverage. When the maximum UE power

is lower than the value, the effective cell coverage for this UE is actuallyreduced by Pcompensation.

The parameters Qqualmin(BSC6900,BSC6910)and Qrxlevmin(BSC6900,BSC6910)can be

set by the MML command ADD UCELLSELRESELor ADD UINTERFREQNCELL.

l If the parameter InterNCellQualReqFlag(BSC6900,BSC6910)is set to True, the values

of Qqualmin(BSC6900,BSC6910)and Qrxlevmin(BSC6900,BSC6910)which are set by

ADD UINTERFREQNCELLwill be used and broadcast through SIB11.

20/230

l Otherwise, the values of Qqualmin(BSC6900,BSC6910)and Qrxlevmin

(BSC6900,BSC6910)which are set by ADD UCELLSELRESELwill be used and

broadcast through SIB3 and SIB4.

There are a maximum of 63 intra-frequency neighboring cells. When the UE in idle state

performs cell selection and reselection, only high-priority 32 neighboring cells of them are

delivered through system messages and selected as candidate target cells. The remaining low-

priority 31 neighboring cells are not delivered, and they are selected as candidate target cells

only when the UE is connected state triggers a handover.

4.2 Cell Reselection

4.2.1 Overview

The signal strength of both serving cell and neighboring cells varies with the movement of a UE

and so the UE needs to reselect the most suitable cell to camp on. This process is called cell

reselection.

When a UE is in idle mode, then

l SIB11 contains information about the UE's neighboring cells for reselection if the parameter

Sib11indis set to TRUE. The neighboring cells include intra-frequency, inter-frequency,

and neighboring GSM cells.

The parameterSib11ind(BSC6900,BSC6910)of intra-frequency cells, inter-frequency

cells, and neighboring GSM cells can be set by running the ADD/MOD

UINTRAFREQNCELL, ADD/MOD UINTERFREQNCELL, and ADD/MODU2GNCELLcommands.

l The UE fails to perform a cell reselection when moving to the cell edge if the parameter

Sib11indis set to FALSE. In this case, the UE selects a new cell to camp on.

NOTE

The parameter Sib11indis set to TRUEby default.

4.2.2 Number of a UE's Neighboring Cells Contained in SIB11

Sections 10.3.8.19 "SIB data fixed" and 11.3 "Information element definitions" in 3GPP TS

25.331 V10.0.0 specify the maximum number of fields that can be contained in SIB11, andtherefore the number of a UE's neighboring cells contained in SIB11 is limited. If more

information about a neighboring cell is contained in SIB11, fewer neighboring cells can be

contained in SIB11.

When SIB11 only contains intra-frequency neighboring cells, inter-frequency neighboring cells,

or neighboring GSM cells, a maximum of 32 neighboring cells can be contained in SIB11. If

more than 32 neighboring cells are configured, select neighboring cells according to the

principles in Table 4-2.

The numbers of intra-frequency neighboring cells, inter-frequency neighboring cells, or

neighboring GSM cells can be queried by running the LST UINTRAFREQNCELL, LST

UINTERFREQNCELL, and LST U2GNCELLcommands.

10 neighboring GSM cells, delete cells based on the ratio 3:2:1.

l If the numbers of intra-frequency neighboring cells, inter-frequency neighboring cells, and

neighboring GSM cells are the same, delete cells in the following order: neighboring GSMcell, intra-frequency neighboring cell, and inter-frequency neighboring cell.

NOTE

Delete onecell from a type of neighboring cells at a time until the total number of neighboring cells is the

same as the maximum number of neighboring cells that can be contained in SIB11.

When SIB11bisunder the parameterSibCfgBitMap(BSC6900,BSC6910)in the ADD/MOD

UCELLSIBSWITCHcommand is selected, SIB11 can contain a maximum number of 96

neighboring cells as follows:

l 32 intra-frequency neighboring cells

l 32 inter-frequency neighboring cells

l 32 neighboring GSM cells

4.2.3 Cell Reselection Process

The cell reselection process is as follows:

1. The UE calculates the serving cell SXaccording to the following formulas:

l Squal= Qqualmeas- Qqualmin

l Srxlev= Qrxlevmeas- Qrxlevmin- Pcompensation

NOTE

l For detailed description of the formulas, see 4 Cell Selection.

l Figure 4-1shows the cell reselection of the UEs in idle mode.

2. The UE decides whether to start the intra-frequency or inter-frequency measurement

according to the Sx and the UE movement state.

l To start the intra-frequency, inter-frequency, or inter-RAT measurement, go to 3. For

details, see 4.2.4 Measurement Start Criteria.

l Otherwise, end the cell reselection.

3. The cells are queued according to the measurement results. The UE selects a suitable cell

to camp on according to the cell reselection criteria. For details, see 4.2.5 Cell ReselectionCriteria.

4.2.4 Measurement Start Criteria

The Hierarchical Cell Structure (HCS) may affect the measurement start criteria for cell

reselection.

Measurement Start Criteria with HCS Not Used

UE Speed Estimation

When determining whether HCS can be used, the RNC needs to consider the UE speed. The UEspeed estimation is performed by RNC.

When HCS is used, the RNC determines the UE movement state according the following

condition:

l When the UE is in the slow movement state

If the number of cell reselection within a period TCRmax(BSC6900,BSC6910)is more

than CRMaxNum(BSC6900,BSC6910), or the RNC notify the UE that the UE is in fast

movement, the UE is in the fast movement state.

l When the UE is in the fast movement

If the number of cell reselection within a period TCRmax(BSC6900,BSC6910)is less thanCRMaxNum(BSC6900,BSC6910),

The UE keeps in the fast movement state for a hysteresis period (TCrmaxHyst

(BSC6900,BSC6910)).

The UE enters the slow movement state when the hysteresis period expires.

Measurement Occasion

When a UE is in the CELL_FACH or CELL_EFACH state, the UE can perform intra-freq at

any occasion and can perform inter-freq or inter-RAT measurement during FACH measurement

occasion.

The UE in CELL_FACH reads the inter-frequency or inter-RAT FACH measurement indicator

contained in SIB11 and SIB12 (if possible) of the cell where the UE camps on.

l If the inter-frequency FACH measurement indicator is TRUE, the UE in CELL_FACH

triggers the measurements on inter-frequency cells corresponding to SIB11 and SIB12 (if

possible).

l If the inter-RAT FACH measurement indicator is TRUE, the UE in CELL_FACH triggers

the measurements on inter-RAT cells corresponding to SIB11 and SIB12 (if possible).

The inter-frequency and inter-RAT FACH measurement indicators carried in SIB11 and SIB12

are respectively controlled by InterFreqInterRatMeasInd(BSC6900,BSC6910)and

FACHMeasInd(BSC6900,BSC6910)in the ADD UCELLMEAScommand.

4.2.5 Cell Reselection Criteria

Definition of Criterion H and Criterion R

Criterion H and criterion R are used for cell reselection.

The quality level threshold criterion H for the HCS is used to determine whether the prioritized

ranking based on the hierarchical cell reselection rules shall apply. If the system informationindicates that the HCS is not used, the quality level threshold criterion H does not apply.

WCDMA RAN




24


29/230

Table 4-8Definitions for criterion H and criterion R

Criterion Definition

Criterion H Hs= Qmeas, s - Qhcss

Hn= Qmeas, n - Qhcsn - TOn x Ln

l Hs is for the serving cell.

l Hn is for the neighboring cell.

l Qmeas, s is the measurement result of the serving cell.

l Qhcssis set by the parameterQhcs(BSC6900,BSC6910)for the serving

cell

l Qmeas, n is the measurement result of the neighboring cell.

l Qhcsnis set by the parameter Qhcs(BSC6900,BSC6910)for the

neighboring cell.

l Qhcsnis set in the following way:

If the parameter AdjsQhcsSwitch is set to ON, Qhcsn is set by the

parameter InterFreqAdjsQhcs or InterRatAdjsQhcs for the neighboring

cell.If the parameter AdjsQhcsSwitch is set to OFF, Qhcsn is set by the

parameter Qhcs for the neighboring cell.

l If the serving cell and the neighboring cell have the same HCS priority

(HCSPrio(BSC6900,BSC6910)), Ln is 0. Otherwise, Ln is 1.

Criterion R Rs=Qmeas, s + Qhysts

Rn=Qmeas, n -Qoffsets, n- TOn x (1-Ln)

l Rs is for the serving cell.

l Rn is for the neighboring cell.

l Qmeas, s is the measurement result of the serving cell. Whether RSCP

or Ec/N0 is measured is controlled by QualMeas(BSC6900,BSC6910)

in the ADD UCELLSELRESELor MOD UCELLSELRESEL

command.

l Qhystsis set by the parameterIdleQhyst1s(BSC6900,BSC6910)(RSCP)

or IdleQhyst2s(BSC6900,BSC6910)(Ec/No) for the serving cell.

l Qmeas, n is the measurement result of the neighboring cell.

l Qoffsets, n

is set by the parameter IdleQoffset1sn(BSC6900,BSC6910)

(RSCP) or IdleQoffset2sn(BSC6900,BSC6910)(Ec/No).

TOn is valid only when HCS is used. The value of TOn is either 0 or the offset for the neighboring

cell (TEMP_OFFSETn). The formula for calculating TOn is as follows:

TOn = TEMP_OFFSETn x W (PENALTY_TIMEn-Tn)

Note that,

l When the value of (PENALTY_TIMEn - Tn) is smaller than 0, the value of W

(PENALTY_TIMEn - Tn) is 0.

WCDMA RAN




25


30/230

l When the value of (PENALTY_TIMEn - Tn) is greater than or equal to 0, the value of W

(PENALTY_TIMEn - Tn) is 1.

TEMP_OFFSETn (TempOffset1(BSC6900,BSC6910)for RSCP and TempOffset2

(BSC6900,BSC6910)for Ec/No) is used as an offset to the H and R criteria for the duration of

PENALTY_TIMEn (TpenaltyHcsReselect(BSC6900,BSC6910)) after a timer Tn (count fromzero) is started for that neighboring cell.

TEMP_OFFSETn and PENALTY_TIMEn are only applicable when the system information

indicates that HCS is in use. Therefore, TOn is applicable only when the system information

indicates that HCS is in use.

Cell Reselection Procedure

Figure 4-3shows the cell reselection procedure. The procedure describes the measurement start

and criteria relationship. The actual procedure varies with UE implementation.

Figure 4-3Cell reselection procedure

First, the UE shall select a cell set in the following procedure:

l If HCS is not used (UseOfHcs(BSC6900,BSC6910)is set to NOT_USED), the UE selects

the cells that fulfill the Criteria S.

l If HCS is usedUseOfHcs(BSC6900,BSC6910)is set to USED) andHCSReselctionSwitch

(BSC6900,BSC6910)is set to ONand the UE moves slowly,

WCDMA RAN




26


31/230

If there are cells that fulfill the Criteria H (H>=0), the UE selects the cells with the

highestHCSPrio(BSC6900,BSC6910)in those cells that fulfill the criterion H0 and

Criteria S.

Else if there is no cell that fulfills the Criteria H (H>=0), the UE selects the cells that

fulfills the Criteria S.

l If HCS is used (UseOfHcs(BSC6900,BSC6910)is set to USED) and

HCSReselctionSwitch(BSC6900,BSC6910)is set to ONand the UE moves fast,

If there is no cell that fulfill the Criteria H (H>=0), the UE selects the cells that fulfills

the Criteria S.

If there are cells that fulfill the Criteria H (H>=0),

If there are cells with HCS priorities (HCSPrio(BSC6900,BSC6910)) lower than the

HCS priority of the serving cell, the UE selects the cells that have the highestHCSPrio

(BSC6900,BSC6910)(lower than that of the serving cell),fulfill the criterion H0

and Criteria S.

If there is no cell with HCS priorities (HCSPrio(BSC6900,BSC6910)) lower than theHCS priority of the serving cell, the UE selects the cells that have the lowestHCSPrio

(BSC6900,BSC6910)(higher than that of the serving cell),fulfill the criterion H0

and Criteria S.

Second, the UE shall rank the cells according to the Criteria R as described in the following

cases:

l If both neighboring GSM and UMTS cells fulfill the Criteria S, the R value is calculated

using the RSCP in the UMTS cell and the received signal level in the GSM cell. The UE

selects a cell with the highest R value.

l If a neighboring GSM cell is ranked as the best cell, the UE reselects to the neighboring

GSM cell. Otherwise, the cell reselection procedure proceeds.

If the measurement quantity is CPICH RSCP (QualMeas(BSC6900,BSC6910)is set to

CPICH_RSCP) for cell selection and reselection, the UE shall reselect to a UMTS cell

with the best signal quality.

If the measurement quantity is CPICH Ec/No (QualMeas(BSC6900,BSC6910)is set

to CPICH_ECNO) for cell selection and reselection, the UE shall perform a second

ranking of all neighboring UMTS cells according to the Criteria R in Table 4-8.

Following the second cell ranking, the UE shall reselect the best ranked UMTS cell.

In all the previous cases, the UE can reselect a new cell only when the following conditions are

met:

l The R value of the new cell is larger than the R value of the serving cell during a time

interval Treselections(BSC6900,BSC6910).

l More than one second has elapsed since the UE camped on the current serving cell.

For details of the cell reselection criteria, refer to section 5.2 "Cell selection and reselection in

idle mode" in 3GPP TS 25.304 V10.0.0.

5Location RegistrationLocation registration is used for the PLMN to trace the current status of the UE. Location

registration ensures that the UE is connected to the network when the UE does not perform any

operation for a long period.

WCDMA RAN

UE Behaviors in Idle Mode Feature Parameter Description 5 Location Registration



28


33/230

5.1 Classification of Location Registration

Location registration refers to the location update for non-GPRS and the route update for GPRS.Location registration is of the following three types:

l Normal location registration

l Periodic location registration

l IMSI attach/detach

5.2 Normal Location Registration

The UE performs normal location registration in the following conditions:

l After being switched on, the UE selects a suitable cell that belongs to a new LA or RA.

That is, the LA or RA is different from that recorded in the USIM before the switch-off of

the UE.

l The UE in idle mode enters the cell of a new LA or RA.

5.3 Periodic Location Registration

Periodic location registration may be used to periodically notify the network of the availability

of the UE. It is controlled by a Periodic Location Update timer (T3212, for non-GPRS operation)

or a Periodic Routing Area Update timer (T3312, for GPRS operation).

The value of T3212 is sent by the network to the UE in SIB 1. The value of T3312 is sent by the

network to the UE in the messages ATTACH ACCEPT and ROUTING AREA UPDATE

ACCEPT. The value of T3312 shall be unique within an RA.

T3212 is set by T3212(BSC6900,BSC6910)on the RNC side. T3312 is set on the CN side.

The description of the timer T3212 is as follows:

l When the UE is switched on or the system information indicates that periodic location

registration shall be applied, and the timer T3212 is not running. Then, the timer shall be

loaded with a random value between 0 and the value of T3212, and shall be started.

l When the timer T3212 reaches its expiry value, the UE shall initiate the periodic location

registration.

l The timer T3212 shall be prevented from triggering periodic location update in connected

mode. When the UE returns to the idle mode, T3212 shall be initialized with respect to the

broadcast timeout value and then be started.

l If the UE performs a successful combined routing area update, a location update over the

Gs interface is also successful for the UE. After that, a combined routing area update,

including a location update, only uses T3312 in the CN. Therefore, T3212 is not used for

a location update and relevant radio resources are saved. However, the location update of

UEs processing CS services still uses T3212 if the network mode changes in such a way

that UEs process only CS services or the MSC and the SGSN is disconnected.

WCDMA RAN




29


34/230

5.4 IMSI Attach/Detach

The IMSI attach/detach process facilitates the fast location registration of the UE in specific

conditions.

The system information broadcast by a cell contains an indicator, which indicates whether the

IMSI attach/detach operation is mandatory in the cell. The UE shall operate in accordance with

the received value of the indicator. This indicator, however, shall not be considered in GRPS

attach/detach.

With the IMSI attach/detach operation enabled, if the UE is switched off or its USIM card is

removed during a cell update or URA update, the UE shall send the CN an IMSI detach message,

preventing the CN from initiating a paging attempt towards the UE.

When the UE returns to the activation state,

l If the UE still stays in the same LA or RA, the UE shall perform a location registration

(LR) request indicating IMSI attach.

l If the UE enters the cell of a new LA or RA, the UE shall perform an LR request indicating

IMSI attach and perform a normal location update.

Whether IMSI attach/detach is allowed for UEs is controlled by ATT(BSC6900,BSC6910)in

the ADD UCNDOMAINor MOD UCNDOMAINcommand.

For details about IMSI attach/detach for UEs, see section 4.5.4 "IMSI attach/detach operation"

in 3GPP TS 23.122 V10.0.0.

6Paging ReceptionThe purpose of the paging procedure is as follows:

l The core network (CN) originates the paging procedure to inform selected UEs of service

requests and to trigger reading of updated UTRAN system information.

l The UTRAN originates the paging procedure to trigger state transitions from URA_PCH

to CELL_FACH or idle mode for selected UEs.

This section involves the following feature

l WRFD-010301 Paging UE in Idle, CELL_PCH, URA_PCH State (Type 1)

l WRFD-010302 Paging UE in CELL_FACH, CELL_DCH State (Type 2)

WCDMA RAN

UE Behaviors in Idle Mode Feature Parameter Description 6 Paging Reception



31


36/230

6.1 Paging Types

Paging UE in Idle, CELL_PCH, URA_PCH State (Type 1)

When an UE is in idle, CELL_PCH, or URA_PCH state, UTRAN sends a paging message to

the UE through the PCCH.

Paging type 1 procedure is used to transmit paging information to the selected UEs in idle mode,

CELL_PCH or URA_PCH state using the PCCH. With this feature, upper layers in the network

can:

l Trigger UE establishing an RRC signaling connection.

l Trigger CELL UPDATE procedure of UE in CELL_PCH or URA_PCH state.

l Trigger reading of updated system broadcast of UE in idle mode, CELL_PCH or

URA_PCH state.

l Trigger releasing signaling connection of UE in CELL_PCH or URA_PCH state.

When the CN sends data to UEs in CELL_PCH or URA_PCH state, the UTRAN shall repeat

the paging process five times in case of a paging failure towards a UE for some reasons (For

example, the UE has moved out of the UTRAN and transferred to an inter-RAT network.). If

the UTRAN still fails to page the UE, the UTRAN considers that the paging towards the UE

fails and releases the RRC connection with the UE.

The maximum number of UTRAN paging retransmissions for UEs in CELL_PCH state and

URA_PCH state is specified by CELLPCHMaxPagingTimes(BSC6900,BSC6910)and

URAPCHMaxPagingTimes(BSC6900,BSC6910), respectively. The two parameters are setwith the SET URRCTRLSWITCHcommand.

Paging UE in CELL_FACH, CELL_DCH State (Type 2)

The network can control the UE in CELL_FACH or CELL_DCH state which has DCCH with

paging type 2 procedures. In paging type 2, UTRAN sends a paging message to the UE in

CELL_FACH or CELL_DCH state through the DCCH or FACH.

6.2 Reception Process

When a UE stays in idle mode, the paging to the UE is performed within an LA or RA or the

whole RNC. The UE receives the paging information from the PICH, and reads the information

on the S-CCPCH.

6.3 Reception Technology

To reduce power consumption, the UE can read the information from the PICH only at a

particular time. This is known as the Discontinuous Reception (DRX) technology. The interval

between two consecutive receiving occasion is called DRX cycle.

For Frequency Division Duplex (FDD), the DRX cycle length shall be 2kframes, where k is an

integer and is determined by the following three parameters:

WCDMA RAN




32


37/230

l CN domain specific DRX cycle length for CS

l CN domain specific DRX cycle length for PS

l UTRAN DRX cycle length coefficient

The description of the parameters is as follows:

l CN domain specific DRX cycle lengths

The UE may be attached to different CN domains with different CN domain specific DRX

cycle lengths. The UE shall store these lengths for all CN domains where the UE is attached

and shall use the shortest one.

l UTRAN DRX cycle length

This parameter value is sent to the UE through the RRC CONNECTION SETUP message

without distinguishing specific CN domain types.

The UTRAN DRX cycle length is set by DRXCYCLELENCOEF(BSC6900,BSC6910)

on the RNC side.

For a UE in idle mode, the DRX cycle length equals the shortest value of the stored DRX

cycle length for the CN domains where the UE is attached, with no signaling connection

established.

For a UE in CELL_PCH state or URA_PCH state, the DRX cycle length equals the shortest

value of the following lengths:

UTRAN DRX cycle length

Any of the stored DRX cycle length for the CN domains where the UE is attached, with

no signaling connection established

NOTE

If you set a great DRX cycle length coefficient, the period for UE detect paging information will be long;therefore, the UE can reduce the power consumption, but the delay for responding to a paging will be long.

accordingly.

WCDMA RAN

UE Behaviors in Idle Mode Feature Parameter Description 7 Broadcast Information Reception

39/230

7.1 System Information

A cell periodically broadcasts system information to UEs in the cell on the Broadcast ControlChannel (BCCH). The system information contains parameters relevant to cell selection and

reselection, measurement management, location registration, route registration, handover, and

power control. With the system information, UEs can access the cell properly.

7.1.1 Structure of System Information

The structure of system information is like a tree, which includes the following items:

l MIB

Master Information Block (MIB) provides reference and scheduling information for a

number of SIBs in a cell or one or two Scheduling Blocks (SBs) in a cell. The MIB contains

only the PLMN types supported and the corresponding PLMN identities.

l SB

Scheduling Block (SB) provides reference and scheduling information for other SIBs. The

scheduling information of an SIB may be included in the MIB or SB.

l SIB

System Information Block (SIB) contains actual system information. It consists of system

information elements (IEs) with the same purpose.

When selecting a new cell, the UE reads the MIB. The UE may locate the MIB through the

predefined scheduling information.

The UE may use the scheduling information in the MIB and SB to locate each SIB to be acquired.

If the UE receives an SIB in a position according to the scheduling information and considers

the content as valid, the UE will read and store the SIB.

7.1.2 System Information Reception

A UE stores SIBs with the cell and PLMN or equivalent PLMN area scope (including their value

tags if applicable) for different cells and different PLMNs, to be used if the UE returns to these

cells.

The UE shall consider the stored SIBs with a certain area scope as invalid in the following

scenarios:

l The UE is switched off.

Except the SIBs about cell selection that are stored in the Universal Subscriber Identity

Module (USIM) card, the UE shall consider all stored SIBs as invalid.

l The UE selects a new cell in the serving PLMN.

The UE shall consider all current SIBs with the cell area scope as invalid.

The UE directly uses the stored SIBs if the following conditions are met:

The UE has stored valid SIBs for the newly selected cell.

The value tags in the stored SIBs are the same as those in the SIBs broadcast by the

newly selected cell.

WCDMA RAN




35


40/230

If any of the preceding conditions is not met, the UE must read the SIBs of the newly

selected cell.

l The UE selects a new cell in a new PLMN.

After selecting a new cell in a new PLMN, the UE shall consider all current SIBs with the

PLMN area scope as invalid.

The UE directly uses the stored SIBs if the following conditions are met:

The UE has previously stored valid SIBs for the selected cell of the new PLMN.

The value tags in the stored SIBs are the same as those in the SIBs broadcast by the

newly selected cell.

If any of the preceding conditions is not met, the UE must read the SIBs of the newly

selected cell.

l The non-access stratum (NAS) informs the AS about a new selected PLMN.

The UE shall consider all stored SIBs with the equivalent PLMN area scope as invalid. For

details, see section 10.1.3 "Reception of SYSTEM INFORMATION messages by the UE"in 3GPP TS 25.331 V10.0.0.

7.2 Cell Broadcast Service Reception

An UE supporting Cell Broadcast Service (CBS) can receive Broadcast/Multicast Control

(BMC) messages in idle mode. The UE receives BMC messages during time intervals that do

not conflict with the UE specific paging occasions.

7.3 MBMS Reception

If all of the following conditions are met:

l The UE has activated MBMS services.

l The MBMS is available in the cell, that is, the MBMS point-to-multipoint Control Channel

(MCCH) information is provided on the Broadcast Control Channel (BCCH).

l The UE is permitted to receive MBMS in the cell.

Then, the UE performs the following operations:

l Receives the MCCH.

l Receives each FACH. The FACH refers to the one on which the MBMS point-to-multipoint

Traffic Channel (MTCH) is mapped, and the MTCH refers to the one that carries an

activated MBMS service without the need of setting up an RRC connection.

l Participates in MBMS counting.

The UE may monitor the MBMS notification Indicator Channel (MICH) and receive the MBMS

point-to-multipoint Scheduling Channel (MSCH).

Step 4 Run the RNC MML command SET UPSINACTTIMER(CME single configuration: UMTSRadio Global Configuration Express > PS Permanent Online Detection Timer Configuration >

PS User Inactive Detecting Timer; CME batch modification center: Modifying RNC Parameters

in Batches) to set Interactive service T1and Background service T1to 1800.

Step 5 Run the RNC MML command ADD TRMFACTOR(CME single configuration: UMTS GlobalConfiguration Express > Transmission Resources Configuration > Factor Table; CME batch

modification center: not supported) and MOD ADJMAP(CME single configuration: NodeB

Configuration Express > IUB_RNC > ATM Transport > Adjacent Node Mapping; CME batch

modification center: not supported) to modify the Iu-PS activation factor. The recommended

value is 10%.NOTE

l After this feature is activated, number of UEs in CELL_PCH or URA_PCH state will increase sharply.

These UEs consume a large number of Iu-PS resources although there is no service data transmission.

l You can adjust the Iu-PS activation factor to avoid the PS admission failure due to increasing number

of UEs in CELL_PCH or URA_PCH state.
