Good day. I am facing a problem with one of my Ericsson cells. It’s an EDGE cell. Defined PDTCH 3, Though cell throughput is very low, around 10~20Kbps. TBF drop rate is also abnormal. 20~30%. CS KPI is very good. DT has been conducted but often speed drops. Analyzing the log file I cant find out nothing. (Nemo log). Can u please help me to overcome the issue. This issue has been raised from a corporate client. Which parameters or KPI can i check in this regard.
if you don’t see anyting abnormal during drivetest, i would suspect a customer problem… could you check
– dl tbf congestion ?
– dl tbf throughput ? (not per cell, but per tbf)
– anything related to DL gprs activity : llc volume ? tbf avg duration ? volume per DL TBF ?
it might be that you have only very very little gprs traffic in that cell therefore you have statistically a lot of chance of seeing gprs signalling for MS with poor radio quality.
