Abstract

PURPOSE:To reduce the influence of the fault of a radio channel upon a telephone line by holding the telephone line when abnormality occurs in radio communication while a cordless telephone device is connected to the telephone line. CONSTITUTION:A fixed device (a) is provided with a communication abnormality detecting means 7 to detect the abnormality of the radio communication and a holding control means 8 capable of controlling the radio channel. Then, if the abnormality of the communication is detected by the communication abnormality detecting means 7 during the radio communication in a state that the fixed device (a) is connected to the telephone line, a CPU 6 releases the radio channel by the holding control means 8, and simultaneously sets the telephone line into a held state. Thus, by turning the telephone line connected before into the held state if the abnormality of the radio communication is detected, troubles given to the remote party and a user of the telephone because of the problem of an apparatus like the abnormality of the radio communication are made minimum.

In FIG. 2(a), 1 is a network control circuit, which is connected to a telephone line. The transmitting circuit 3 and the receiving circuit 4 are connected to the network control circuit 1 via the audio circuit 2. Reference numeral 5 denotes an antenna, which is connected to the transmitting circuit 3 and the receiving circuit 4. Reference numeral 6 denotes a CPU, which is connected to the audio circuit 2, the transmitter circuit 3, and the receiver circuit 4.

In FIG. 2(b), 9 is an audio circuit, which is connected to the listener 7 and the microphone 8. In FIG. Reference numeral 12 denotes an antenna, which is connected to the audio circuit 9 via the transmitting circuit 10 and the receiving circuit 11.

Reference numeral 13 denotes a CPU, which is connected to the audio circuit 9, the transmitter circuit 10, and the receiver circuit 11. 14 is the operation unit and CPU1
Connected to 3.

Next, the operation of the above conventional example will be explained.

In FIG. 2(b), by operating the operation unit 14, the CP
The U13 controls the transmitting circuit 10, the receiving circuit 11, and the antenna 12 to perform wireless data communication with the fixed station (a), and the CPU 6 controls the network control circuit to wirelessly communicate with the telephone line. It can be performed.

Problems to be Solved by the Invention However, in the above-mentioned conventional cordless telephone device, when a temporary communication abnormality occurs during wireless data communication, a difference in status occurs between the fixed device and the mobile phone, and the cordless telephone device There was a problem in that the operation of the system was hindered.

The present invention solves these conventional problems,
To provide a highly convenient cordless telephone device that compensates for the disadvantages of wireless communication systems. In order to achieve the above object, the present invention provides a communication abnormality detection means for detecting the occurrence of a wireless communication abnormality in a fixed device. The system is equipped with a hold control means that can control the wireless line.

Therefore, according to the present invention, if a communication abnormality is detected by the communication abnormality detection means during wireless communication in a state where the fixed device is connected to a telephone line, the CPU causes the suspension control means to terminate the wireless communication. Release the line and place the phone line on hold. When an abnormality in wireless communication is detected in this way, the already connected telephone line is put on hold to minimize the damage caused to the other party and the user due to the equipment problem of abnormal wireless communication. Can be done.

Example FIG. 1 shows the configuration of an embodiment of the present invention.

In FIG. 1, (a) is a block diagram of a fixed device, and (b) is a block diagram of a mobile telephone.

In FIG. 1(a), 1 is a network control circuit, which is connected to a telephone line. The transmitting circuit 3 and the receiving circuit 4 are connected via the audio circuit 2 to the network control circuit l. Reference numeral 5 denotes an antenna, which is connected to the transmitting circuit 3 and the receiving circuit 4. 6 is a CPU, a network control circuit 11, an audio circuit 2,
It is connected to a transmitting circuit 3 and a receiving circuit 4. Reference numeral 7 denotes a communication abnormality detection means, which is configured to obtain information on the state of wireless communication from the receiving circuit 4 and to inform the CPU 6 of a communication abnormality. Reference numeral 8 denotes a hold control means which is configured to control the network control circuit 1 and the audio circuit 2 to set the telephone line on hold, and is also configured to control the transmitting circuit 3 and receiving circuit 4.

In FIG. 1(b), 11 is an audio circuit, which is connected to a receiver 9 and a microphone 10. In FIG. Reference numeral 14 denotes an antenna, which is connected to the audio circuit 11 via the transmitting circuit 12 and the receiving circuit 13. Reference numeral 15 denotes a CPU, which is connected to the audio circuit 11, the transmitting side 12, and the receiving circuit 13. Reference numeral 16 denotes an operation section, which is connected to the CPU 15.

Next, the operation of the above embodiment will be explained.

In FIG. 1(a), when the CPU 6 detects a communication abnormality by the communication abnormality detection means 7 during wireless communication with this device connected to a telephone line, the hold control means 8 causes the transmitting circuit 3 and the receiving circuit to It controls the circuit 4 to release the wireless line, and also controls the network control circuit 1 and the audio circuit 2 to set the telephone line on hold.

Effects of the Invention As is clear from the above embodiments, the present invention has the following advantages: - By putting the telephone line on hold when an abnormality occurs in wireless communication while the one-dress telephone device is connected to the telephone line,
It is possible to minimize the influence of wireless line failures on telephone lines.
