LTE&UMTS Cell Reselection V3.0

1 Cooperation Strategy

Figure 1.1 General Strategy

Figure 1.2 MBS currently strategy

IDLE Mode

• As MBS UMTS strategy currently, IDLE UMTS UE always camp in F1 carrier

• IDEL LTE UE will cell reselection down to co-site F1 carrier and adjacent F1

carrier when LTE RSRP is less than -118dBm

• IDLE UMTS UE will cell reselection up to LTE network when LTE RSRP is

more than -112dBm.

3 Command

3.1 LTE script

3.1.1 Change IDLE Timer

MOD RRCCONNSTATETIMER:UEINACTIVETIMER=20;

3.1.2 Configure LTE Switch:

MOD ENODEBALGOSWITCH: HoAlgoSwitch=IntraFreqCoverHoSwitch-

1&InterFreqCoverHoSwitch-1;

3.1.3 Configure LTE Access Signal:

MOD CELLSEL: LocalCellId=xx, QRxLevMin=-64;

3.1.4 Configure LTE Priority

MOD CELLRESEL: LocalCellId=xx, SNonIntraSearchCfgInd=CFG,

SNonIntraSearch=6, ThrshServLow=5, CellReselPriority=5;

3.1.5 Add UMTS Frequency

ADD UTRANNFREQ: LOCALCELLID=xx, UTRANDLARFCN=xxxx,

UTRANVERSION=HSPA, UTRANFDDTDDTYPE=UTRAN_FDD,

UTRANULARFCNCFGIND=NOT_CFG, CELLRESELPRIORITYCFGIND=CFG,

THRESHXLOW=8,CELLRESELPRIORITY=4;

3.1.6 Add UMTS cell information

ADD CELLRESELUTRAN:LOCALCELLID=xx,SPEEDSTATESFCFGIND=NOT_CFG;

3.2 UMTS script

3.2.1 UMTS NodeB version

MOD UNODEB: NodeBProtclVer=R9;

 (If existing UMTS version is lower than R9, we should configure NodeB version as R9; else

no need this command)

3.2.2 Active UMTS SIB19

MOD UCELLSIBSWITCH: CellId=xxxxx, SibCfgBitMap=SIB19-1;

3.2.3 Configure UMTS Priority

MOD UCELLSELRESEL: Cellld=xxxx, SPriority=4;

(If the current UMTS priority is 4, No need this command)

3.2.4 Configure LTE Priority

ADD UCELLNFREQPRIOINFO: CellId=xxxx, EARFCN=xxxx, NPriority=5,

ThdToHigh=8, EMeasBW=xx, EQrxlevmin=-64;
