Reason of call drop in 2G?

[Matulpagla]

Hi,

I am using GNEX Assistant software & in 2G logfiles it was showing call drop event. When I was checking the L3 messages I got the following sequences-

1. "DL channel release" in downlink
2. "Disconnect" in uplink

After disconnect message MS start reading system information & stop sending measurement report. Radio condition was good/acceptable (Rxlev, RxQual, FER, BER, C/I etc)during period.

What could be the possible reason for this call drop?

Thanks
