Abstract: A wireless communications device 2 comprising a wireless control function unit 11, a Bluetooth control function unit 12, and a user interface unit 13, wherein the device has, as the Bluetooth, at least one of a (i) Hands-Free Profile, (ii) Dial-up Networking Profile/Personal Area Network Profile, and (iii) Generic Object Exchange Profile.

Abstract: A communication terminal having a wireless communication facility including sending and receiving a message which is sent to a receiving terminal without a send request from a receiving terminal through a message center, including: a message sending/receiving unit sending and receiving the message; a time control unit controlling current time; a message analysis unit analyzing a message which is sent by a message center, received by the message sending/receiving unit, and includes time information assigned by a message center, and retrieving the time information; and a time setting unit setting in the time control unit a time indicated by the time information retrieved by the message analysis unit as a current time.

Abstract: A mobile terminal device has an electric-power-reduction operation mode for operation with reduced electric power consumption. The mobile terminal device includes an emergency determining unit that determines whether there is an emergency; and an operation mode control unit that controls to shift to the electric-power-reduction operation mode when the emergency determining unit determines that there is the emergency.
