dear all expert,
i have a question about CE-wbbp allocation on huawei cell. in a nodeb , it's ce utilization still low (about 10-20 %). but some cell in this Nodeb has ULCE congestion. is there are anyone who can share about manual allocation of CE-WBBP ?
How you did evaluation? which counters/KPIs you are monitoring ?

HI..
1. Go to MMLCommand NodeB : DSP LICENSE ==> check CE License
2. Check DSP BRD, for Example :
SP BRD:;
3244082G_3G_TANJUNG_KERITING
+++ 3244082G_3G_TANJUNG_KERITING 2011-03-16 12:05:16
O&M #8312
%%/*37030*/DSP BRD:;%%
RETCODE = 0 Succeed.
Board Status
------------
Cabinet No. Subrack No. Slot No. Board Type Standby Status Availability Status Operate State Admin State
Master 0 3 WBBP NULL Normal Enabled Unblocked
Master 0 7 WMPT Active Normal Enabled NULL
Master 0 16 UBF NULL Normal Enabled NULL
Master 0 19 UPEA NULL Normal Enabled NULL
Master 11 0 NFAN NULL Normal Enabled NULL
Master 4 0 WRFU NULL Normal Enabled Unblocked
Master 4 2 WRFU NULL Normal Enabled Unblocked
Master 4 4 WRFU NULL Normal Enabled Unblocked
(Number of results = 8)
--- END
Check whether the CE is Normal or unconfigured..
3. Check the WBBP type itself by LST BRDINFO then put Cabinet No=0, Subrack No =3, you will find the type of WBBP..
HEre is WBBP type u should check. You should set the license as same as its capacity board.
HBBI ==> UL/DL = 128/256
EBBI ==> UL/DL = 384/384
WBBPa ==> UL/DL = 128/256
WBBPb1 ==> UL/DL = 64/64
WBBPb2 ==> UL/DL = 128/128
WBBPb3 ==> UL/DL = 256/256
WBBPb4 ==> UL/DL = 384/384
Thanks,
Paul

Hi dodotiro,
May i know how many DL/Ul group it has?
I also face to this problem...
Please refer to link below for my post....

Pay attention as sometimes ULCE congestion is due to external interference, if the configuration of the channel elemts is correct.
Hi, what counters or formula are you using to evaluate your utilization of CE (i.e. UL.Shared.group or DL.shared.group)? does it happen only in busy hour? Is this a RAN sharing sites?
