Abstract
A method and a User Equipment, UE (120) for detecting that the UE has received a fraudulent missed call, e.g. from a non-legitimate device (150). 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.
Claims15
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.
A user equipment (UE) in a communications network for detecting that the UE has received a fraudulent incoming call which is determined to be a missed call because it is determined that the incoming call ended before a user of the UE has answered the incoming call, wherein the missed call has a duration, the UE comprising:
- memory;
- and
- processing circuitry coupled to the memory, wherein the UE is configured to:
- determine the duration of the missed call;
- indicate the duration of the missed call;
- and
- transmit, 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.
