Hi Da Architect ! i always agree with your good practical sense 😉
Hashem, your problem lacks details. you must spend more time collecting clues…
when you say “signal strength goes up & down”, and then you say “we’re sure we don’t have a problem on the radio”.
well, you MUST have a problem on the radio, obviously.
perhaps, check for sector crossing, or TRX crossing…
problem 1 : are you connected on one cell or is the difference of rxlev due to the MS changing cells quickly ? Is it during idle mode or dedicated mode ?
problem 2 : call end = call drop ? check qos stats : what is the highest cause of drops on this cell ? perform a trace : what is the reason of the call release ?
give us more data, if you want help 🙂
