Slave device information transmitter (127) of the present disclosure transmits slave device information to a mobile phone. Slave device transfer data receiver (122) receives slave device transfer data from the mobile phone, and stores the slave device transfer data in storage (103). Destination slave device determiner (123) extracts destination slave device information from slave device transfer data stored in storage (103), and selects a cordless phone 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 transmitter (125) transmits slave device transfer data to a cordless phone slave device selected by destination slave device determiner (123).

Cordless telephone equipment includes a portable unit and a base unit. The base unit includes: a portable unit control section controlling a communication protocol with the portable unit through a wireless interface wirelessly connecting with the non-IP terminal type portable unit; a wireless LAN interface section transmitting and receiving packet data to and from a wireless IP terminal and wireless LAN access point; a wireless LAN bridge control section forwarding the received packet data to the wireless IP terminal, or the wireless LAN access point, or within the base unit in accordance with a destination address of the packet data received through the wireless LAN interface section; and a base unit control section processing the packet data received from the wireless IP terminal and forwarded within the base unit, as data received from a portable unit under control of the base unit.

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.

A portable device can transmit information through one of a mobile phone network and an Internet, wherein the portable device includes a text-based communication module to allow a user may synchronously transmit or receive data through a local area network, wherein the data is text, audio, video or the combination thereof. The text-based communication module of the portable device includes a text-to-speech recognition module used to convert a text data for outputting the text data by vocal, and a read determination module for determining read target terminals and unread target terminals when a user of the portable phone device activates the read determination module.

Telephone directory data stored in storage unit (103) of a cordless telephone device of the present invention is data in which a telephone directory serial number, name information, telephone number information, and thumbnail image data are associated with each communication partner. With respect to telephone directory data, slave device transfer data transmitting unit (125) transmits only telephone directory serial number and thumbnail image data after conversion in association with each other, to the cordless phone slave device. In a case where there is an incoming call destined to a specific cordless phone slave device from a subscriber line, call control unit (121) transmits the telephone directory serial number, the name information, and the telephone number information of the telephone directory data of a caller, together with incoming information, to the cordless phone slave 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.
