[0002]

2. Description of the Related Art In general, a radio telephone such as a car telephone transmits and receives a radio signal through a general telephone line via a base station. Calls can be made, and calls can be made over a wide range of several kilometers to several tens of kilometers.

On the other hand, cordless telephones have been widely used in homes.

[0004] A cordless telephone is composed of a fixed machine connected to a telephone line and a mobile machine communicating wirelessly with the fixed machine.
When a ring is input from the telephone line, the fixed device detects this and transmits a call signal to the mobile device. When the user performs a call operation in response to the call signal, the signal is transmitted to the fixed device, and the fixed device closes the telephone line to establish a call state with the caller. The voice signal input from the telephone line and the user's voice signal input from the microphone of the mobile device are communicated between the mobile device and the fixed device by radio signals, respectively, so that a call can be made. The radio wave range of a cordless telephone is about 10m to 20m for a weak type and 10 for a low power type according to the Radio Law.
It is about 0 m.

[0005]

However, although the above-mentioned wireless telephone has a wide communication range, the charge is generally higher than that of a public telephone line. On the other hand, cordless telephones make calls with fixed equipment connected to the public wireless telephone line, so they can make calls at the price of the public telephone line, but they can talk only with the corresponding fixed equipment. In order to be able to do so, the range of the call was narrowed.

In addition, there is a device that automatically switches to the appropriate one, but since the device itself automatically connects to either the base station of the wireless telephone or the fixed device connected to the public telephone line, the operator Did not recognize the incoming call from either.

[0007] For this reason, the operator, in order to know that whether the incoming call to a call of Dochi Rakara after incoming inquires to the caller whether the call from either of the fixed unit or base station I had to do the same and it was troublesome.

Further, if a call is made without making this inquiry, a long-time call will be made despite the fact that the call is received from the base station of the wireless telephone device, and the call charge of the caller will be considerably high. If the incoming call comes from the base station of the wireless telephone device within the fixed device's call range, the user may be notified that the incoming call may be from the fixed device, Occasionally I could not get out of range.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention is directed to a radio telephone device which can be connected to both a base station of a radio telephone and a fixed machine connected to a public telephone line. It is an object of the present invention to provide a wireless telephone device that allows a user to identify whether the call is from a fixed machine connected to a public telephone line.

[0010]

The operation of the wireless telephone of the present invention configured as described above will be described below with reference to the operation flowchart of FIG.

First, an incoming call operation when the automatic selection mode is selected by the selection switch 25 will be described. In addition,
It is assumed that the changeover switch 26 has been switched to the standby mode. When the changeover switch 26 is in the standby mode in the automatic selection mode, the control unit 29 turns on the transistors 16 and 18 and supplies power to the receiving units 3 and 10.

Whether a calling signal is input from the base station to the receiving unit 3 of the radio telephone A (step 1, hereinafter, step is abbreviated as S), or the cordless telephone unit B
It is detected whether or not a calling signal is input from the fixed machine to the receiving unit 10 (S2). When a calling signal is input from the base station in S1, the signal received by the receiving circuit 6 via the antenna 1 and detected and amplified by the detection and amplification circuit 7 is output to the control means 29. When the control means 29 detects the calling signal of its own device, it controls the calling signal generating circuit 22 to cause the sounding body 23 to generate a calling sound. When the user sets the changeover switch 26 to the call mode in response to the ringing tone (S
3), the control means 29 turns on the transistor 15 (S4),
The power is supplied to the transmitting unit 2 so that the transmitting unit 2 transmits a response signal. Further, the display means 27 displays the use of the wireless telephone (S5). As a result, a call is established with the caller (S6). When the call is ended and the changeover switch 26 is switched to the standby mode (S7), the control means 29 causes the transmitting section 2 to transmit a call end signal (S8), and switches the display of the display means 27 to the standby state (S7). S9) The transistor 15 is turned off (S10).

Next, a case where a calling signal is input from a fixed machine of a cordless telephone will be described.

First, when a ring signal is input from the telephone line 41, the ring signal detecting means 42 of the fixed machine detects this and outputs it to the control means 49. The control means 49 includes a modulation circuit 46,
A call signal is transmitted from the antenna 44 through the high-frequency transmission circuit 45. When the calling signal is transmitted, the signal is received by the receiving circuit 13 via the antenna 8, and the signal detected and amplified by the detection and amplification circuit 14 is output to the control means 29. When the control means 29 detects the calling signal of its own device (S2), the calling signal generating circuit 22
And a ringing tone is generated from the sounding body 23. Note that the ring tone at this time is different in tone color or cycle from the ring tone of the wireless telephone, so that it can be determined from which ring the call has been made. When the user sets the changeover switch 26 to the call mode in response to the ringing tone (S11), the control means 29 turns on the transistor 17 (S12), and supplies power to the transmitting unit 9;
The transmitting unit 9 transmits a call start signal. Further, the display means 27 displays the use of the cordless telephone (S13), and the switching means 21 is switched to the cordless telephone side (S14). When the response signal is detected by the control means 49 via the receiving circuit 47 and the detection and amplification circuit 48 of the fixed machine, the interface circuit 43 is controlled, the telephone line 41 is closed, and the communication state with the caller is established.
(S15). When the call ends and the changeover switch 26 is switched to the standby state (S16), after the transmission section 9 transmits a call end signal (S17), the display of the display means 27 is switched from the cordless telephone to the display of the standby state (S18). ), The switching means 21 is switched to the wireless telephone side (S19). Next, the transistor 17 is turned off (S20), and the supply of power to the transmission unit 9 is stopped.

Next, the calling operation will be described with reference to FIG.

First, when the changeover switch 26 is switched to the talking mode (S21), the control means 29 turns on the transistor 17 (S22), supplies power to the transmitting section 9, and causes the transmitting section 9 to transmit a calling signal. At the same time (S23), the switching means 21 is switched to the cordless telephone (S24). Further, the timer 30 is turned on (S25). When the fixed machine detects this signal, it transmits a response signal through the modulation circuit 46 and the high-frequency transmission circuit 45, controls the interface circuit 43, and controls the telephone circuit 41.
Is closed. When the response signal from the fixed machine is received by the receiving unit 10 and detected by the control unit 29 (S26), the control unit 29 causes the display unit 27 to display the use of the cordless telephone (S27),
Thereafter, the communication with the telephone line 41 is enabled (S28). Subsequently, when a dial signal is inputted from the dial signal input means 24, the control means 29 causes the transmitting section 9 to transmit the dial signal, and the telephone circuit 41 is transmitted through the receiving circuit 47, the detection and amplification circuit 48, and the interface circuit 43 of the fixed machine. To send a dial signal. When the changeover switch 26 is switched to the standby state after the end of the call, the same operation as the above-described incoming call operation is performed.

Next, if the timer 30 expires (S29) without detecting a response signal in S26 because the telephone is out of the communication range of the cordless telephone (S29), the control means 29 sets the transistor 17
Is turned off, the transistor 15 is turned on, the supply of power to the transmission unit 9 is stopped, and power is supplied to the transmission unit 2 (S30). Further, the switching means 21 is switched to the wireless telephone side (S31). Next, the transmitting unit 2 transmits a call signal to the base station of the wireless telephone (S32), and causes the display means 27 to display the use of the wireless telephone (S33). This allows the wireless telephone to communicate (S34). Subsequently, when a dial signal is input from the dial signal input unit 24, the control unit 29 causes the transmission unit 2 to transmit the dial signal, and enters a talking state with the called party. . When the changeover switch 26 is switched to the standby state after the end of the call, the same operation as the above-described call operation is performed.

Next, when the radio telephone mode is selected by the selection switch 25, the control means 29 turns off the transistors 17 and 18 and does not supply power to the transmission section 9 and the reception section 10 of the cordless telephone. Here, when the changeover switch 26 is in the standby mode, the control unit 29 turns on the transistor 16 and supplies power to the receiving unit 3 of the wireless telephone. Subsequent incoming and outgoing operations are the same as in the above-described automatic selection mode, and the same as the telephone operation in the wireless telephone.

Next, the case where the cordless telephone mode is selected by the selection switch 25 will be described.

First, the control unit 29 turns off the transistors 15 and 16 and does not supply power to the transmission unit 2 and the reception unit 3 of the wireless telephone. Further, the switching means 21 is switched to the cordless telephone. Here, when the changeover switch 26 is in the standby mode, the control unit 29 turns on the transistor 18 and supplies power to the receiving unit 9 of the cordless telephone.
The subsequent incoming and outgoing call operation is the same as the above-described call operation on the cordless telephone in the automatic selection mode.

When the changeover switch 26 is in the off mode, all the transistors 15, 16, 17, and 18 are off regardless of the selection state of the selection switch 25.
