Poor DL throughput in Huawei during Drive Test while moving

[parsarka]

Hi Experts,
I am facing terrible problem in DL throughput in EDGE/GPRS while moving in car.My PDP gets activated & after that most of the time the DL throuhput remains 0kbps.Please suggest urgently which all parameters I should change to resolve this issue in Huawei system.

did you do drive test during stationary if you have still problem or not.

agree...and maybe you should try to conduct ping test and see if the test is successful.

Hi,
I have done the ping test & seen that the RTT is high,around 1200ms.The throuhput is better in static & poor while moving.Any parameter suggestions???

Of course you have less throughput in moving because every time when you make cell reselection you loss your TBF connection and again re-established , there is feature that makes TBF released delay. check and activated it will improve if you have huawei i can tell you. and long RTT is also the same reason but one thing you can ask what is the TCP configuration .

you can check if your test is at the edge of the cell, because bad radio condition (low signal level or interference) mainly affected GPRS/EDGE throughput (CMIIW).if it does than you can refer to RF Engineer suggestion regarding the TBF release delay...

are you downloading from FTP server or http address?
if it http, try another add,
you can also check your serving cell at that point if it is configure for data.

Dear,
Let me know in how many cells you have this problem?
For one cell? one site? or one BSC? or one region?
There are so many counters (Timers) to solve this one!!!
Let me know just in upload or download??
