The base unit is connected to the public telephone network as a fixed station. At time t0, a call signal is transmitted from the exchange of the public telephone line network to the master. The parent machine notifies the child machine of the receipt of the call and sends the ID code of the parent machine. The child device confirms that the ID code of the parent device is registered in advance, and then responds to the calling and sends the ID code of the child device to the parent device. The parent device confirms that the ID code of the child device is registered in advance, specifies the channel used for the call to the child device, and the child device returns an acceptance response. When the master unit commands the slave unit to ring the bell and the user of the slave unit hears the bell and responds from the slave unit,
The base unit responds to the exchange with the incoming call. Next, the master unit instructs the slave unit to turn on the voice circuit. When the cordless handset turns on the voice circuit, the user of the cordless handset starts a call with the other party of the call from time t1. When the user of the child device performs an operation for ending the call at time t2, the parent device notifies the exchange of the end of the call.

Frequency bands of radio waves used for wireless communication in cordless telephones are assigned in advance as a plurality of channels. Combinations in which each cordless telephone shares the allocated frequency band and is identified by the ID code even if other base units and handset units exist within the range of radio waves and the ID code is registered in advance. Communication is possible only between the parent device and the child device. In a cordless telephone or the like, the combination of a fixed station and a mobile terminal is not fixed, and a new mobile terminal can be registered as a slave.
