Abstract
A method and a User Equipment, UE () for detecting that the UE has received a fraudulent missed call, e.g. from a non-legitimate device (). When receiving a missed call which is ended before a user of the UE has answered the incoming call, the UE determines the duration of the missed call, and indicates, e.g. to a user of the UE, the 5 duration of the missed call. The missed call may be determined as potentially fraudulent if the duration of the missed call is below or equal to a predetermined threshold.
