Did you check the CHR and cell trace , I had this issue before and it was caused from a a user in area who is using a mobile with waki waki software ,
Did you ask for Drive test using another equipment
did you check using the KPIs history ,since when the issues are happening

Thanks You for answer.

Good idea to check CHR and cell trace : just can you tell me how i can investigate with this method.
This Pb of CS drop is generalized on many cells and i don't think that is related to a particular mobile.
Using KPIs this Pb appear at first time in different date on many cells.

Try the UMTS FMA in this forum.you can load the CHR files downloaded from RNC to analyse.This will give you UE info as well.

I have experience it was related to the XPU Load. Maybe you can check the XPU load or the Board Load.
