hi,
if you are on the 3G network:
most probably the problem is a LAC border problem so you are having a lot of ping pongs location update while having the call. you can solve this problem by adding Qoffset2s,n to prevent the ping pong location updates.

if you are on the 2G network:
and I think this is most probably your case (because you said that the problem is happening in a lot of places) then most probably the problem will be that your MS is attached to EDGE (getting email or something, specially if you are using smart phone), and as you know that multi services are not supported in the 2G network so the paging will get lost.
however there is a feature which is called "BSS paging Co-ordination" that can pause the EDGE data to receive the paging and then resume it again after the call is finished.

so please clarify which of the above cases are you facing.

thanks,
Mohamed Magdy El-Hakim

First of all, many thks for your advices, it's help me a lot
Last day, I tested by using 02 MS call each other, then do imsi tracing and get the message to analyze. But everything seem ok
Maybe something happened with the media gateway part ?

I've had the issue a few years back. Sometimes I got the missed call message, sometimes just noise was coming so the user hanged up. After extensive tracing we discovered that the interface between RNC/MGW was wrongly cabeled. Once we set the installation correctly everything worked fine again. You need a specialist RNC/BSC engineer to help.
