Could not observe this in drive test but just on the mobile phone. QoS stats for the cell are normal. One thing i’ve noticed that call drop mostly occur occurs due to handover failurein concentric cell with seperate BCCD assigned to both EGSM900 and DCS1800.

I’ve also observed that this messege often comes long after RLT may have expired. for example in the cell, RLT value in seconds is 15 but the call after being silent goes on till 23 secs or more and then messege of error in connection comes on screen. sometimes it is even before the expiry of RLT. Can it be due to some core end problem?
