DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone device for home use, business use, public use and the like.

[0002]

2. Description of the Related Art FIG. 6 shows a configuration of a conventional cordless telephone. Reference numeral 11 denotes a base unit of the cordless telephone, which is connected to a telephone line or the like by wire so that outgoing / incoming, incoming / outgoing calls can be made with the external line. Connected wirelessly. A control command is transmitted from the transmitter 13 incorporated in the base unit 11 using a wireless channel as a control channel as a reception request, and the slave unit 12 also uses the wireless channel as a control channel,
After receiving and analyzing the data by the sixteen receivers 16, a reception permission signal is transmitted from the transmitter 16. Base unit 1
In step 1, the data is analyzed, the wireless channel is switched to the communication channel, and voice communication is started. During communication, the transmission / reception data is occupied by communication data such as voice because the wireless channel is a communication channel, and transmission / reception of control commands becomes impossible. At the end of the call, the wireless channel is switched to the control channel again and an end command is exchanged to end the call.

As described above, in the above-mentioned conventional cordless telephone device, the base unit and the base unit can perform outgoing / incoming, incoming / outgoing calls with the base unit and an outside line by wireless communication.

[0004]

However, in the above-mentioned conventional cordless telephone, since the wireless communication between the master unit and the slave unit is analog communication, when an arbitrary control command is to be exchanged during communication, each time, Since the wireless channel must be switched between the call channel and the control channel, the user can remotely control other devices during a call, execute an application built in the master unit or the slave unit, and connect to these devices. It was impossible to control the equipment.

An object of the present invention is to provide a cordless telephone device capable of transmitting and receiving control information during wireless communication.

[0006]

According to the present invention, in order to achieve the above object, communication between a master unit and a slave unit is realized by digital communication, and a part of a communication channel is used for communication of control information. A digital control function during communication (during a call) is provided to a slave unit, a master unit, or a device connected thereto.

[0007]

According to the present invention, since the control information can be communicated during the communication between the master unit and the slave unit by the above-described configuration, for example, it is possible to control electronic devices other than the master unit and the slave unit. Becomes
