dear expert ?
i have a UMTS cell that only have PS AVG TROUGHPUT onli 25 kbps ? how can i improve that troughput ?
hey buddy ,
in order to help you have to share more info like :
DL is on HSDPA or R99 ?
what is the throughput KPI you are using ?
the throughput value is on the peak hour or on daily basis ?
this is R99 throughput. i am using this KPI = sum of ( VS.bkg.dl.32 + VS.int.dl.32 + ..+ 384 ). the result is DL throughput is not more 25 kbps, while UL Throughput reach ~120 kbps. i've check other KPI such as CSSR, CCSR ,RTWP, IUB utilization, IUB configuration are just fine.
is there anything else that i have to check /
How about these counters?
VS.PS.Bkg.Kbps.DL8, VS.PS.Bkg.Kbps.DL16,VS.PS.Bkg.Kbps.DL32.....VS.PS.Bkg.Kbps.DL384
VS.PS.Int.Kbps.DL8,VS.PS.Int.Kbps.DL16......................................VS.PS.Int.Kbps.DL384
VS.PS.Str.Kbps.DL8..................................................................VS.PS.Str.Kbps.DL384
i think you missed typing the names of the counters . the names should be as jayk said .
if yes , then as you said those are only R99 counters ==> maybe most of your traffic is carried by HSDPA (if it's activated , or HSPA+) .
in case of HSDPA (no HSUPA) ==>
- DL R99 traffic will be small
- UL R99 traffic will be bigger than DL R99 traffic .
- HSDPA will carry most of the traffic where by Huawei default settings : each RAB with MBR >= 64Kbps will be mapped to HSDPA .
for HSDPA check this kpi :
HSDPA RLC Throughput=VS.HSDPA.MeanChThroughput.TotalBytes*8/{SP*60}/1000 ....... (R12 KPI)

i see. so every traffic >64kbps will be switched to HSDPA, isn't it ? that is why PS UL Troughput can reach 128 kbps, but DL only 25 kbps .
another question (wild thinking). is there any idea to improve it , let say i want minimum PS DL Troughput 128 kbps, above it will be switched HSDPA.
what paramater i must set to fulfill that condition ?
It's recommended to push more ps traffic on HS because it will provide more capacity (# of users) , throughput & resource utilization .
