Why Iphone 7/7Plus users are facing lot of call drops in good radio condition?

During analysis observed drop call is happend due to Security Mode reject and Cause Code as Radio Interface Failure.

Call is established successful ly,But Routing Area Update got failed because the UE does not answer to SecurityModeCommand.

Requesting you to please provide the best solution.
