Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a signal transmission system of a telephone.

[Technical background of the invention] With the development of the information service network, as shown in FIG. 5, a computer system 3 is connected to a public telephone line network 1 and a computer from a car telephone 9 to a computer via a home telephone 5 or a base station 7. A system for calling the system 3 and receiving various information registered in the computer system 3 has been put into practical use.

[Problems of background art] In this case, when the operator of the home telephone 5 or the car telephone 9 receives information from the computer system 3,
It becomes possible to receive information through the procedure of transmitting a dial signal corresponding to the dial number of the computer system 3 and, after connecting the line, transmitting a number signal corresponding to its own registration number or identification number. There is. For this reason, there is a problem that the call operation corresponding to the two numbers of the dial number of the computer system 3 and the self registration number (or identification number) has to be performed, and the operation is troublesome. Also, since the user performs the operation of transmitting his / her own registration number (or identification number, etc.) signal with confirmation of the line connection, the call time after the line connection is extended by the time required for this call operation, and the call charge increases. There was a problem. For this reason, the two number data are separated by the identification code and stored in the memory, and the number is set to 2 each time the send key provided separately is operated.
A signal transmission system has been proposed in which one dial number is read out one by one and a signal corresponding to this dial number is transmitted. The invention according to this proposal makes it possible to transmit a plurality of number signals in a short time by an extremely simple operation.

However, in the case of the above method, it is necessary to store a plurality of telephone number data in the memory and a plurality of identification codes for partitioning each of the plurality of telephone numbers. Here, for example, if 4 bits are required to store one identification code and the number of telephone number data to be stored is n, in this case, 4 × (for storing the identification code, Since a memory capacity of n-1) bits is required, there is a problem that the efficiency of use of the memory deteriorates. Further, in the case of this method, it is necessary to search for the above-mentioned identification code for the transmission processing of a plurality of telephone number data, which complicates the processing, lengthens the processing time, and deteriorates the use efficiency of the control unit. There was also a problem.

[Object of the invention] Therefore, an object of the present invention is to solve the above-mentioned problems by using a small amount of memory to simplify the operation of transmitting a signal corresponding to stored number data, and at least two or more signals in a short time. It is an object of the present invention to provide a signal transmission system of a telephone capable of transmitting a number signal.

[Summary of the Invention] In order to achieve the above object, the present invention connects a line to a destination by transmitting the first number information to a public telephone line network, and then, through the connected line. In the signal transmission method of the telephone for sequentially transmitting other number information to the other party, the first number information input by operating the keypad is displayed on the display means, and the condition that the store key is operated here is used as a condition. The first number information is stored in the first address of the storage means, the address of the storage means is switched according to the operation of the key for instructing the delimiter, and then the other number input by the operation of the keypad. The information is displayed on the display means, and on the condition that the store key is operated again, the other number information is stored in the address switched according to the operation of the key for instructing the delimiter. By repeating this operation, the first number information and the other number information are sequentially stored in different addresses of the storage means, and thereafter, by operating the send key, the first number information is stored from the storage means. To connect the line to the other party by transmitting this to the public telephone line network, and subsequently, every time the transmission key is operated, the other number information stored in the storage means according to the address is displayed. It is characterized by sequentially calling and automatically transmitting the called other number information sequentially to the connected line.

[Embodiment of the Invention] An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 and FIG. 2 are a block diagram and a hardware circuit diagram showing the outline of the signal transmission system of this embodiment. The dial keypad 11 is provided with dial keys having a code such as "*" in addition to the numeric dial keys. The function key section 13 is a store key 1 for instructing registration of dial numbers.
5, recall key 17 for reading the registered dial number and displaying it on the display unit, send key for instructing the transmission of the signal corresponding to the dial number displayed on the display unit
19, equipped with a clear key 21 for clearing the displayed dial number. The dial keypad 11 is a control unit
It is connected to the dial number memory 25 of 23. Also, the store key 15, recall key 17, send key 19, clear key 2
Reference numerals 1 and 2 indicate a registration instruction means 27 and a display instruction means 2 in the control unit 23, respectively.
9. Connected to the sending instruction means 31 and the deletion instruction means 33. The registration command means 27 issues a command to store the number data in the dial number memory 25 when the store key 15 is input. The display command means 29 displays the number data stored in the dial number memory 25 when the recall key 17 is input.
This is what is displayed on the 35. The sending command means 31 is a sending key
When 19 is input, the number data stored in the dial number memory 25 is sent to the dial signal generator 37. The erasure command means 33 clears the stored contents of the dial number memory 25 when the clear key 21 is input. The dial number memory 25 is connected to the dial signal generator 37. When the send key 19 of the function key unit 13 is pressed, the number data stored in the dial number memory 25 is passed through the dial signal generator 37 as a number signal from the line terminal 39 to a computer system or the like via a switching network (not shown). Sent. Reference numeral 41 is a communication circuit, and reference numeral 43 is a handset.

As shown in FIG. 2, the control unit is a central processing unit (CPU) 4
5, program memory 47, data memory 49, dial number memory 25, input / output circuits 51, 53, 55, 57. Dial keypad 11, function key section 13, display 35,
The dial signal generator 37 is connected to the bus line BUS of the CPU 45 via the input / output circuits 51, 53, 55 and 57, respectively.

Next, the operation of this embodiment will be described. The CPU 45 monitors the key operation of the dial key pad 11 and the function key unit 13 via the input / output circuits 51 and 53. When the key operation is performed on the dial key pad 11 for registering the number, the program memory 47 is stored. Of the stored programs, the program shown in the flowchart of FIG. 3 is started. It is assumed that the number data registered in the dial number memory 25 is 3 (3 sets). In step 301, the address index i = 1 in the dial number memory 25 is set. In step 303, the CPU 45 waits for the number data to be input. When the number data is input, the number data is temporarily stored in the data memory 49 in step 305.
To display on the display 35. When the store key 15 of the function key section 13 is entered in step 309 and the "*" key on the dial keypad 11 is entered, step
At 311 the number data temporarily stored in the data memory 49 is stored in the address Xi of the dial number memory 25. In step 313, the address index i is incremented by 1.
When the store key and the “*” key are not input in the determination of step 309, or when the processing of step 313 ends, it is determined whether or not the clear key 21 is input in step 315, and when the clear key 21 is not input. Return to step 303. When the second number data is input thereafter, the processing from step 303 to step 315 is similarly repeated and the second (second set) number data is stored in the address X ₂ of the dial number memory 25. Similarly, the third (third set) number data is stored in the address X ₃ of the dial number memory 25.

The registration operation of these dial numbers is performed before calling the called side. Clear key instead of store key 15
When 21 is input, the number data stored in the data memory and dial number storage memory are deleted in step 317, and the display on the display is cleared in step 319. In this case, the process returns to step 301 and the registration operation of the number data is performed again. The three sets of number data are registered as described above.

Next, the operation of sending the three sets of number data stored in the dial number memory 25 to the dial signal generator 37
A description will be given based on the flowchart in the figure. Step 401
Wait until the recall key 17 is input in the function key section 13 and the "*" key of the dial keypad 11 is input. When these two keys are input, the address index i = 1 is set in step 403. . In step 405, the input of the send key 19 is awaited. When this send key 19 is input, the number data stored in the address X ₁ is read in step 407, and this number data is supplied to the dial signal generator 37. Then, this first number data is converted into a number signal (DTMF signal) by the dial signal generator 37 and sent to the line terminal 39.

Next, at step 411, the address index i is incremented by 1. When it is determined in step 411 that the line with the called side has been connected by the transmission of the number signal, the input key of the transmission key 19 is waited for in step 413.

When the send key 19 is input, it is determined in step 415 whether or not the line is disconnected. If the line is not disconnected, the process returns to step 407 and the number signal based on the second number data is the line terminal. It is sent via 39 to a computer system (not shown). Similarly, a number signal based on the third number data is also sent to the computer system by the processing from step 407 to step 415. If the line is closed in step 415 after the first transmission of the number signal, the flow returns to step 401 to wait for the input of the recall key 17 again.

With the above configuration, the dialed number data of the called side, the registration number data of the calling side and the transmission information data are registered in advance in the dial number memory 25, and the transmission key 19 is operated three times to obtain three number data. A corresponding number signal can be sent. Therefore, the dial operation (signal transmission operation) becomes extremely simple, and the time required for transmitting the number signal transmitted after the line connection is significantly shortened, so that the communication cost can be saved. At this time, the number stored in the dial number memory 25 is only the number data, and the code for separating the dial numbers is not necessary. That is, every time one number data is input, the address of the memory for storing each number data is switched by operating the “*” key, so that only each number data is sequentially stored in the memory, which is the same as the conventional method. The use of inefficient memory such as number data, *, number data, * ... "is eliminated. Further, a program for performing a search process of code data for separating these number data is not required, and the CPU usage efficiency is improved.

In the present embodiment, signals corresponding to three sets of number data can be sent, but it goes without saying that the number of sets is not limited to this.

As described above in detail, according to the present invention, each time one piece of number information is input, the address of the memory for storing each piece of number information is switched by operating a key for instructing a break. Therefore, only the respective number information is sequentially stored in the memory. Therefore, it is possible to use a small amount of memory to simplify the operation of transmitting the number signal and to send at least two sets of number signals in a short time.
