Problem Solving of :

Power Congestion

For UL Power Congestion : 1st Solution Step:1. Check MAXTXPOWER per Cell in LST UCELL2. Upgrade from 430 to 460 (RNC and NodeB must be set the same)

2nd Solution Step:1. Check LST UCELLCAC2. Check UL total equivalent user number (ULTOTALEQUSERNUM) max setting is 2003. If it’s still default, then upgrade it to 150 or 2004. Then Check LST UCELLALGOSWITCH5. Set NBMUlCacAlgoSelSwitch (Uplink CAC algorithm switch ) = ALGORITHM_SECOND6. Set NBMDlCacAlgoSelSwitch (Downlink CAC algorithm switch) = ALGORITHM_FIRST

3rd Solution Step:1. Check LST UCELLALGOSWITCH2. In NBMLdcAlgoSwitch, Set UL_UU_LDR (Uplink UU LDR Algorithm: )=1 (ON)3. Then check UCELLLDR,4. Set UlLdrFirstAction (UL LDR first action) = BERateRed(BE traff rate reduction),

UlLdrBERateReductionRabNum=1, GoldUserLoadControlSwitch=ON

Power Congestion

For DL Power Congestion :

1st Solution Step:1. Check LST UCELLCAC2. Check DL total equivalent user number (ULTOTALEQUSERNUM) max setting is 2003. If it’s still default, then upgrade it to 150 or 2004. Check DL total power threshold (default is 90%), Set to 95%5. Then Check LST UCELLALGOSWITCH6. Set NBMDlCacAlgoSelSwitch (Downlink CAC algorithm switch ) =

ALGORITHM_SECOND

2nd Solution Step:1. Check LST UCELLALGOSWITCH2. Set DL_UU_LDR (Downlink UU LDR Algorithm: )=1 (ON)3. Then check UCELLLDR,4. Set DlLdrFirstAction (DL LDR first action) = BERateRed(BE traff rate reduction),

DlLdrBERateReductionRabNum=1, GoldUserLoadControlSwitch=ON

Code Congestion

For any code congestion :1.Check the traffic distribution in Mapinfo, and do traffic sharing using adjacent parameter changing2.In crowded area (a lot of nodeB cell servings), reduce the active set numbers (3 2) . This will impact to the code used for reselection process3.Reduce HS-SCCH’s code number from 4 to 2. HS-SCCH (max 4 per UE) is only used to decode the next HSPDSCH frame4.Reduce User Number for Code Adjust for HSDPA = 3 (This is used in LDR, but in code reshuffling, it also need 2 codes in the process, this mean in the same time total code that will be used is 6 codes)5.Increase maximum number of HSDPA in a cells6.Set the Allocate Mode HSDPA to automatic, and set the proper number of HS-PDSCH code7.Activate code LDR Algorithm and set the LDR on 1st action with Code Adjust8.Add 2nd, 3rd, etc carriers9.owntilt the antenna10.Etc..

Code Congestion

For any Iub congestion :1.Add E1/IP migration2.Create FTI (Factor Table Index)3.In new created FTI, reduce the percentage number of packet transmitted in Iub (PSINTERDL, PSINTERUL, PSBKGDL, PSBKGUL, etc)

To create TFI :

1. Add TRMFACTOR (to set the reduced PS in Iub)2. Check ADJNODE (Check ANI of the nodeB)3. Set ADJMAP for FTI

Code Congestion

Other NCCR

1. MOD UCELLRLACTTIME : OAMGUARDVALFORHIGHRATE (H-Rate RL NodeB Message

Processing Time) no response/no reply2. MOD UFACH : Max Transmit Power of FACH (No response/no reply)3. MOD UCELLSETUP (MOD UCELL) : NINSYNCIND, NOUTSYNCIND, & TRLFAILURE4. MOD UINTRAFREQNCELL (adjacent parameter) : IdleQoffset1sn[dB],

IdleQoffset2sn[dB], ConnQoffset1sn[dB], & ConnQoffset2sn[dB]5. HSPA+ Activation : DSP LICENSE (activate DL 64QAM Function)

LST UCELLALGOSWITH : Cell Hspa Plus function switch = Cell 64QAM Function Switch : ON & Cell 64QAM+MIMO Function Switch::ON
