CASES-NCCRPower CongestionCode CongestionIuB CongestionCE Congestion Problem Solving of :

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

2nd Solution Step:Check LST UCELLCACCheck UL total equivalent user number (ULTOTALEQUSERNUM) max setting is 200If its still default, then upgrade it to 150 or 200Then Check LST UCELLALGOSWITCHSet NBMUlCacAlgoSelSwitch (Uplink CAC algorithm switch ) = ALGORITHM_SECONDSet NBMDlCacAlgoSelSwitch (Downlink CAC algorithm switch) = ALGORITHM_FIRST

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

Power CongestionFor DL Power Congestion :

1st Solution Step:Check LST UCELLCACCheck DL total equivalent user number (ULTOTALEQUSERNUM) max setting is 200If its still default, then upgrade it to 150 or 200Check DL total power threshold (default is 90%), Set to 95%Then Check LST UCELLALGOSWITCHSet NBMDlCacAlgoSelSwitch (Downlink CAC algorithm switch ) = ALGORITHM_SECOND

2nd Solution Step:Check LST UCELLALGOSWITCHSet DL_UU_LDR (Downlink UU LDR Algorithm: )=1 (ON)Then check UCELLLDR,Set DlLdrFirstAction (DL LDR first action) = BERateRed(BE traff rate reduction), DlLdrBERateReductionRabNum=1, GoldUserLoadControlSwitch=ONTo see the effect of LDRVS.LCC.LDR.InterFreqVS.LCC.LDR.BERateDLVS.LCC.LDR.BERateUL

Code Congestion

For any code congestion :Check the traffic distribution in Mapinfo, and do traffic sharing using adjacent parameter changingIn crowded area (a lot of nodeB cell servings), reduce the active set numbers (3 2) . This will impact to the code used for reselection processReduce HS-SCCHs code number from 4 to 2. HS-SCCH (max 4 per UE) is only used to decode the next HSPDSCH frameReduce 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)Increase maximum number of HSDPA in a cellsSet the Allocate Mode HSDPA to automatic, and set the proper number of HS-PDSCH codeActivate code LDR Algorithm and set the LDR on 1st action with Code AdjustAdd 2nd, 3rd, etc carriersowntilt the antennaEtc..

Code Congestion

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

To create TFI :Add TRMFACTOR (to set the reduced PS in Iub)Check ADJNODE (Check ANI of the nodeB)Set ADJMAP for FTI
