Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a dial tone generator for generating a dial tone sent to a telephone transmitter.

B1 Summary of the Invention The present invention is a dial tone generator for generating a dial tone sent to the transmitter of a telephone, which stores telephone number information sent from a base station in a memory or the like, and stores the telephone number information sent from a base station, except when transmission is on hold. After a predetermined period of time has elapsed after receiving the telephone number, the telephone number information is read out and converted into a dial tone, thereby making it possible to easily dial and send the telephone number without much effort.

C8 Prior Art Land mobile radio telephone systems such as so-called car telephones have been put into practical use. In the current system, the base station performs sophisticated control such as mobile station location registration and channel switching, which has the disadvantage of high charges. To improve this, a new land mobile radio telephone system called a convenience radio phone has been proposed. In this convenience radio phone, the base station side does not perform advanced control such as location registration for mobile stations, thereby simplifying the system and making it more economical. For this reason, the system is basically dedicated to calls (transmissions) from mobile stations such as cars.

D0 Problems to be solved by the invention However, since it is inconvenient that the mobile station does not have any incoming call function, for example, the pager (1986-
It has been proposed to use a display-type pager that displays telephone number information of the other party (contact information) sent from a base station, such as Japanese Patent No. 142,545. However, looking at the phone number displayed on the pager and pressing the number key on the phone (to dial) is troublesome, and doing so while driving poses a safety problem. Also, there is a risk of getting the number wrong.

Also, for example, an automatic dialing device (Utility Model No. 55-143
(Refer to Publication No. 59, etc.) When used in conjunction with tl-, and if you store the telephone number information of the person you are likely to contact with relatively frequently in memory, etc., the information sent from the base station, that is, displayed on the pager, can be displayed. If the telephone number entered is one that has been stored, normal speed dial transmission will be possible. However, there is a drawback that it is cumbersome to compare the telephone number information sent from the base station and the telephone number information stored in a memory or the like. Additionally, if the telephone number information sent from the base station is not what is stored, you would have to press the number key on the conventional telephone to send it, which would eliminate the problem described above. I can't escape it.

SUMMARY OF THE INVENTION The present invention was proposed in view of the above-mentioned conventional problems, and an object of the present invention is to provide a dial tone generating device that can easily perform dial transmission without requiring much effort. do.

Information matching detection means and this identification information
telephone number detection means for detecting the telephone number information from the output of the demodulation means in accordance with the detection output of the detection means;
a memory means for storing the telephone number information detected by the telephone number detection means; a read hold switch means for suspending the reading of the telephone number information stored in the memory means; readout initiation means for starting a readout operation of the memory means when the readout hold switch means is not operated within a period of time; and dialing signal formation for forming a dialing signal corresponding to the telephone number information read from the memory means. and electroacoustic converting means for converting the dial signal from the dial signal forming means into a dial tone.

F1 Effect According to the present invention, unless the read-out hold switch means is operated, the read-out start means reads out the telephone number information stored in the memory means a predetermined time after reception, and the telephone number information corresponding to the telephone number information is read out by the read-out start means after a predetermined time after reception. A dial signal is generated by the dial signal forming means, and this dial signal is converted into a dial tone by the electroacoustic converting means and output.

G. Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a circuit configuration of a dial tone generator according to an embodiment. A base station (not shown) connected to a general subscriber telephone network (PSTN) transmits at least identification information (ID information) and telephone number information in response to a connection request from a general subscriber telephone to a mobile station (mobile device) such as a car. A signal consisting of is transmitted. This signal is received by a demodulation circuit 2 via an antenna 1 and demodulated. The demodulated output from the demodulation circuit 2 is sent to the telephone number detection circuit 3 and also to the ID detection circuit 4. In the ID detection circuit 4, the ID information is detected from the output of the demodulation circuit 2, and this output is used as the ID-
The signal is sent to the output circuit 5. The ID-number configuration circuit 5 compares the detected ID information with the own ID information, and if a match is detected, the telephone number detection circuit 3
A coincidence detection signal is sent to the demodulation circuit 2 in response to the coincidence detection signal.
An operation is performed to detect the above-mentioned telephone number information from the output. The detected telephone number information is stored at a predetermined address in the memory 60, and further sent to the liquid crystal drive circuit 7 and displayed on the liquid crystal display 8.
The phone number corresponding to the above phone number information is displayed. Further, the coincidence detection signal from the ID-number construction circuit 5 is sent to the CPU ((::en-tral process
In response, a lighting control signal is sent from the CPU 9 to a lamp lighting circuit 10, so that an incoming call lamp 11 indicating an incoming call is turned on. The liquid crystal display 8 is capable of displaying, for example, about two lines, as shown in FIG. This second
In the figure, two telephone numbers are displayed, but this is an example of a case where calls are received consecutively, and they are displayed in the incoming call list. Also, the phone number information received later is stored in the memory 6.
is stored at another address. If more calls are received, the LCD display 8 will display "1....." and "2.
..." is displayed as "2....." or "3.."
...", and the newly received telephone number is displayed in this "3....." area.

The memory 12 is a conversion table for converting the telephone number information stored in the memory 6 into information on the name of the company, etc. that corresponds to the telephone number information, and the name and telephone number of the recipient(s) with whom you are likely to contact frequently. Number information is stored in advance. The name information stored in the memory 12 is sent to the liquid crystal drive circuit 7, and the display is changed according to the display switching control signal supplied from the CPU 9 to the liquid crystal driving circuit 7 by operating the display switching key 13 (see FIG. 2). The switching is done and the LCD display 8
The name corresponding to the above name information is displayed. Note that, of course, if information corresponding to the telephone number information stored in the memory 6 is not stored in the memory 12, the display will not be switched.

The hold key 14 (see FIG. 2) serves as a read-hold switch means for holding read-out of the telephone number information stored in the memory 6.

Further, when the hold key 14 is not operated within a predetermined time after receiving the information, the CPU 9 serving as a reading start means sends a read start control signal to the memory 6, and the telephone number information is read out. The telephone number information read from the memory 6 is transmitted to the dial signal forming circuit 1.
5, and a dialing signal corresponding to the telephone number information is formed. This dial signal is converted into a dial tone by a speaker 16 using an electroacoustic conversion means and output. In FIG. 2, the speaker 16 is provided at a position within the housing 30 corresponding to the sounding section 22 which has an annular member 21 made of rubber or the like on the periphery, and the speaker 16 is placed on the sounding section 22 at a position corresponding to a ring-shaped member 21 made of rubber or the like. A telephone set (not shown) is placed there. Therefore, the dial tone from the speaker 16 is sent to the above-mentioned transmitter for transmission.

That is, if the hold key 14 is not operated, the dial transmission will be automatically performed after a predetermined period of time has passed after reception. For example, if the driver is driving on a road with many curves and is unable to talk on the phone, if the hold key 14 is operated within a predetermined time, the transmission will be put on hold. It looks like it will be done. In this case, transmission is performed by operating the hold key 14 again.

Note that if two or more calls are received, transmission is normally performed in the order of arrival. Also, when the first call arrives, hold key 1.
4, transmission is put on hold, and if a second call arrives thereafter, unless the hold key 14 is operated, the transmission will be made to the second telephone number. In this case, if the hold key 14 is further operated, the message will be sent to the first telephone number.

Further, the terminal 17 is a terminal for manual operation of the number keys (numeric keypad) 23 in FIG. 2, and the transmission order can also be specified using the number keys 23.

Further, by operating the memory key 18, it is possible to store number information etc. manually input using the above-mentioned keys. For example, by storing information on an abbreviated number and the telephone number of the other party, it is possible to send an abbreviated dial. .

Next, an example of the operation will be schematically explained with reference to the flowchart in FIG. First, ■D match comparison detection circuit 5
Then, it is detected whether the ID information sent from the base station matches the ID information of the own station (step ■).
. If the ID information does not match, this step (2) is executed again, but if a match is detected, the telephone number detection circuit 3
Detection of the telephone number information and storage of the detected telephone number information into the memory 6 are performed (step 2).

Subsequently, the incoming call lamp 110 is turned on and the telephone number corresponding to the above-mentioned telephone number information is displayed on the liquid crystal display 8 (step (2)). Next, it is determined whether or not the hold key 14 has been pressed within a predetermined time after reception (step 2). If the hold key 14 is not pressed, the telephone number information is read from the memory 6 and the speaker 1
6, a dial tone corresponding to the above telephone number information is generated (step ■). As a result, transmission occurs automatically. Next, the read telephone number information is erased from the memory 6 (step 2). On the other hand, if the hold key 14 is pressed in step (2) above, it is determined whether or not the hold key 14 has been pressed again (step (2)). This step ■' is executed repeatedly until the hold key 14 is pressed, but when the hold key 14 is pressed, steps ■ and step ■ are executed.

In this way, when receiving a call, you can
Dial transmission can be performed reliably.

Also, if you are in a situation where you cannot make a call, press the hold key 1.
4 allows you to suspend transmission, which is very convenient.

Note that it is more convenient if the hold key 14 is provided, for example, on a part of the steering wheel (steering wheel). Further, in the above-described embodiment, the incoming call is notified by the incoming call lamp 11, but the incoming call may be notified by a buzzer sound, a voice generated by a voice synthesizer, or the like. Furthermore, the dial tone generating device of the present invention may be incorporated into a part of a telephone, and in this case, it can also be used as a number key.

H0 Effects of the Invention As is clear from the description of the embodiments described above, in the dial tone generating device of the present invention, the telephone number information stored in the memory means is stored in the readout start means unless the readout hold switch means is operated. After a predetermined time has elapsed after reception, the information is read out and a dial tone is generated. Therefore, dial transmission can be easily performed without much effort.

Further, for example, while driving on a road with many curves, transmission can be suspended by operating the read suspension switch means, which is very convenient. Furthermore, since there is no need to perform troublesome key operations while driving, safety problems can be eliminated, and there is no risk of incorrect numbers.
