Abstract

PURPOSE:To prevent ringing of a subscriber's equipment by connecting the subscriber's equipment and a radio equipment of a base station in parallel via a relay and disconnecting the subscriber's equipment from the line when a radio equipment of a mobile station makes a dial. CONSTITUTION:The subscriber's equipment 4 is connected to terminals 11, 11' of the radio equipment 5 of the base station and a subscriber line 2 is connected to terminals 12, 12' and the terminals 11, 11' and 12, 12' are connected in parallel via the relay 13. Further, a realy 9 is connected between the terminal 12 and a transmitter T and a receiver R. A control circuit 10 connected to the transmitter and receiver circuits T.R controls the relays 9, 13. The relays 9, 13 are in the contact state normally and when a dial signal comes from the radio equipment 6 of the mobile station, the reception section R is demodulated and the control circuit 10 intermits the relay circuit 9 in synchronization with the dial signal to turn off the relay 13. Thus, the dial signal from the mobile station 6 does not enter the subscriber's equipment to prevent the incoming ring tone from mixed with the dial signal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radio telephone device comprising a base station radio device and a mobile station radio device which are connected to a subscriber line in parallel with the present telephone.

In conventional wireless telephone devices, the dial signal sent from the device to the subscriber line also flows to the telephone because the base station radio device and the telephone are connected in parallel to the subscriber line. Therefore, the telephone's bell also rang in synchronization with this dial signal, which could cause the telephone to mistake it for the ringing tone of an incoming call.

Figure 1.2 is a diagram for explaining the configuration of a conventional wireless telephone device. Figure 1 shows the connection state of the wireless telephone device, and Figure 2 shows the details of this telephone and the base station wireless device. It is a diagram. The main channel 4 is connected to the subscriber terminal 3 of the subscriber line 2, which accommodates the exchange IK. A base station wireless device 5 that performs wireless communication with the mobile station wireless device 6 is also connected in parallel. This telephone 4 has Pell 8, Hook Switch 7,
It consists of a telephone circuit, a handset, etc. The base station wireless device 5 includes a relay circuit 9 for sending dial signals.
, a hybrid, a transmitting/receiving device, a control circuit 10, and the like. When a dial signal is transmitted from the mobile station radio device 6, the base station radio device 50 control circuit 10 causes the relay circuit 9 to operate intermittently and connects the exchange l via the subscriber line 2.
Sends out a dial signal.

However, as mentioned above, since the telephone 4 and the base station radio equipment 5 are connected in parallel to the subscriber line, there is a drawback that the bell of the telephone also resonates as the dial signal is sent out.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless telephone device that does not cause the bell of the telephone to ring in response to a dial signal.

In order to achieve the above object, the wireless direct communication device according to the present invention is a wireless direct communication device consisting of a base station radio device and a mobile station radio device which are connected to a subscriber line in parallel with the present telephone.
The base station wireless device has a subscriber line connecting end A and B, and a first
a relay circuit, a connection end of the main telephone connection connected to the subscriber line connection end via the first relay circuit, a second relay circuit, and a second relay circuit connected to the subscriber line connection end via the first relay circuit. a transmitting/receiving device that is connected to the subscriber line connection end and sends and receives signals to and from the mobile station wireless device; and a control circuit that controls the relay circuit and controls the second relay circuit so as to disconnect the telephone while the first relay circuit is in operation.

According to the above configuration, resonance of the bell of the telephone can be prevented, and the object of the present invention is completely achieved.

Hereinafter, the present invention will be explained in more detail with reference to the first page.

FIG. 3 is a diagram showing an embodiment of a base station radio device constituting a radio telephone device according to the present invention. The base station radio device 5 has a connection end 11,11' for the telephone 4 and a connection end for the subscriber line 2.

A first relay circuit 13 is inserted between the telephone connection terminal 11' and the subscriber line connection 412.12'. The second relay circuit 9 connects the subscriber line connection end 12 to the transmitting/receiving device #I.
It is inserted between T and R. The control circuit 10i; is connected to the transmitting/receiving devices jiT, R, and the transmitting/receiving devices T,
The first and second relay circuits 13 are connected by a signal from R.
．． Control 9. The control of the control circuit 10 is the same as the conventional one except for the operation of the part related to the present invention. Normally, the relay circuits 13 and 9 are in the form of a single chain, and the telephone connection end 11.11' and the subscriber connection end 12.12' are in a connected state, respectively. When a dial signal is transmitted from the mobile station radio device 6, the signal is demodulated by the demodulation section of the receiving device TL, and the presence or absence of the dial signal is detected by the control section 10. When it is determined that there is a dial signal, the relay circuit 9 is operated intermittently in synchronization with the dial signal, and the dial signal is sent to the subscriber line. During this time, the relay circuit 13 is also opened, and the telephone connection end 11.11' and the subscriber line connection end 12.12' are disconnected. Note that the relay circuit 9 is opened and closed for each digit of the dial signal to send out the dial signal.

Due to the operation of the relay circuit described above, no dial signal is sent to this telephone.

As described above in detail, the device i! according to the present invention! Since the telephone is configured to be disconnected from the base station radio equipment when the dial signal is sent out, resonance of the telephone can be prevented.
