1. A method performed by a user equipment (UE) in a communications network for detecting that the UE has received a fraudulent incoming call, the method comprising:
receiving, at the UE, an incoming call, wherein the incoming call is determined to be a missed call because the incoming call is determined to have ended before a user of the UE answered the incoming call and wherein the missed call has a duration;
determining, by the UE, the duration of the missed call;
indicating the duration of the missed call to a user of the UE; and
transmitting to a network node a message comprising call duration information indicating the duration of the missed call, wherein the message indicates the missed call is potentially fraudulent.
