A system and method for authenticating a caller may include receiving an incoming call from the caller, determining a gender of the caller, and selecting, based on the determined gender, to search for the caller in one of: a watchlist of untrustworthy female callers, and a watchlist of untrustworthy male callers.

A communications method includes receiving, by user equipment (UE), a first message from a network side, where the first message is used to indicate to the UE to perform circuit switched fallback (CSFB) as a called party, where the first message includes first information, and where the first information is used to indicate an incoming call number. If it is determined that a preset condition is met, the communications method further includes sending a second message to the network side, where the second message is used to indicate that the CSFB is rejected, and where the preset condition includes at least one of the incoming call number is restricted or the UE is in a mode of automatically rejecting a CSFB incoming call.

A method for managing an incoming call in a communication terminal is described, the incoming call having an associated call identifier. The method can comprise checking the routing of an outgoing call to the call identifier associated with the incoming call, and classifying the incoming call on the basis of the result of the checking of the routing, the incoming call being classified as a malicious incoming call if the checking of the routing reveals that the outgoing call is not able to be routed. The method can be used, for example, to detect malicious calls or spam.

A method for establishing a telephone communication between a first terminal and a second terminal. The first and second terminals each have a main caller identifier, and the second terminal additionally has a secondary caller identifier. This method is implemented when the user of the first terminal seeks to communicate with the user of the second terminal by using the secondary caller identifier of the second terminal. The method allows redirecting the telephone call of the first terminal to a voicemail system associated with the secondary caller identifier when the user of the second terminal does not answer this telephone call. The voicemail system is associated with a voicemail system caller identifier selected from a database connected to a communication management platform.

A communication device (202) comprises one or more sensors (208) configured to generate sensor data, a wireless interface (206, 306), and a processor (210, 310). The wireless interface is configured to establish a connection with a remote device (402) according to a short-range wireless communication protocol and to transmit one or more signals to the remote device, the one or more signals representing information configured according to a media format. The processor is configured to determine at least one activity mode based on the sensor data from the one or more sensors on at least one of the communication device or the remote device, and during the transmission of the one or more signals, control the wireless interface to increase a transmit power level to a maximum transmit power level based on the determined activity mode.

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.
