Disclosed is cordless telephone equipment allowing various kinds of data stored in a mobile telephone to be stored in a cordless handset in a state usable therein, without provision of a new device thereto. A handset transfer-data conversion section that executes a predetermined conversion process according to a type of handset transfer-data stored in a storage section. Specifically, the handset transfer-data conversion section converts an audio format of ringtone data according to a use CODEC of a cordless handset. In addition, the handset transfer-data conversion section converts an image size of wallpaper data into a size reproducible in the cordless handset. Further, the handset transfer-data conversion section converts an image size of image data of the other party included in telephone directory data into a size reproducible in the cordless handset.

A mobile device (200) for receiving an audio signal from a source (390) via a base station (300) is disclosed. The mobile device comprises a first wireless communication interface (220) operable to communicate using a first mode of wireless communication; a second wireless communication interface (230)_operable to communicate using a second mode of wireless communication, the second mode having a shorter range than the first mode; and a controller (210) configured to switch from receiving the audio signal from the base station via the first wireless communication interface to receiving the audio signal via the second wireless communication interface when the mobile device is proximate to the base station.

There is provided an intercom system capable of reducing power consumption by stably performing wireless communication between a camera and a monitor. Monitor 200 checks whether or not a communication error occurs in image data received from camera 100, and checks whether or not there is a slot as a moving destination in an empty state in a case where the communication error occurs. In a case where there is no slot as the moving destination, monitor 200 controls the number of connected image calls by transmitting an image call disconnect request to camera 100. Accordingly, intercom system 10 varies image quality (a frame rate, a compression ratio, or an image size) depending on a radio wave status.

A digital enhanced cordless telecommunication (DECT) base station, the DECT base station may include a transmitter that is arranged to transmit, at different points of time, downlink transmitted DECT signals to another DECT device that differs from the DECT base station; a receiver that is arranged to receive from the other DECT device downlink reception information indicative of attributes of downlink received DECT signals that were received by the other DECT device as a result of the transmission of the downlink transmitted DECT signals; a processor that is arranged to process the downlink reception information to detect a motion that affects a reception of the downlink received DECT signals by the other device.

Slave device information transmitting unit of the present invention transmits slave device information to a mobile phone. Slave device transfer data receiving unit receives slave device transfer data from the mobile phone, and stores the slave device transfer data in storage unit. Destination slave device determining unit extracts destination slave device information from slave device transfer data stored in storage unit, and selects a cordless telephone slave device which is a destination of the slave device transfer data, based on destination slave device identification information which is set in the destination slave device information. Slave device transfer data transmitting unit transmits slave device transfer data to a cordless telephone slave device selected by destination slave device determining unit.
