Hi,
Usually abnormality happens due to UE abnormal behaviour. If you had 2 MS during drivetest, if yes then try which MS was having more HO failures.

Secondly for every drop/HO failure, investigate reasons from layer3 messages. I am sure you will be able to figure out exact problem.

Hi Imran;

Would you please clarify for me what you mean by UE abnormal behaviour, you are right we used two MS one for short call ans secod for long call and the block calls are result from the short call test.

Hi

u have to check two parts

1) Check the UE/MS performnace- it may have bad hardware/software
2) CORE timers set to low value , so that BSS may not peg actuall drop!!
