Abstract

PURPOSE:To send a DTMF signal tone to a paging terminal the same as a key telephone set by outputting a message data inputted from a data input switch group from a ring tone generator as the DTMF signal tone. CONSTITUTION:The paging receiver is brought into the DTMF message input/ sending enable state by turning on a mode changeover switch 21 and a data is inputted from a data input switch group 22. When the data is inputted, a CPU15 stores the inputted datainto the internal RAM and displayed on a LCD display device 16. When the display is checked and if there is any error, after it is corrected and a reset button 20 is depressed, a series of input information is outputted from a speaker 18 as the DTMF signal tone by a DTMF signal oscillator 19.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a paging receiver having the ability to send message data from a dial pulse telephone.

(Prior Art) Paging systems have made remarkable progress in recent years, and services that display and call messages such as numeric information and even text information have been realized, from services that only make calls. In this case, the caller must use a push-button telephone that can send dial signals even after the line is connected, although input is normally made from a regular telephone. This is because dial pulse telephones cannot send dial signals until the line is connected.

(Problems to be Solved by the Invention) As described above, in the conventional paging system, only a push-button telephone can be used as a call input device for a paging service with a message.

Considering that even in Japan, which is a country with advanced telephone technology, the penetration rate of push-button telephones is still less than 50%, this is a very serious obstacle to the popularization of paging services with messages.

In addition, even if you are using a button telephone, when you try to input text information, a paging terminal has a function to convert a combination of predetermined numbers or a combination of special keys (# or %) and numbers into characters or symbols. Although it is possible to input messages from a push-button telephone by holding the button, there are problems in that the input operation is complicated and it is not possible to confirm whether or not the input is accurate. In consideration of the problems of conventional paging receivers with message display, a key-operated device similar to a button telephone and a double-tone multi-frequency signal tone (Double To
ne Multt Frequency:hereinafter referred to as DTMF
By providing a DTMF signal oscillator that converts into a DTMF signal and sends it out, messages can be entered even from a general dial pulse telephone, and the message content can be displayed on the display by converting numbers and special key combinations and lines before sending. This is an attempt to provide a paging receiver with a message sending function that can be confirmed.

(Means for Solving the Problems) The present invention has the following configuration to achieve the above object. That is, the message sending paging receiver of the present invention:
A data input for inputting message data in a paging receiver that receives subsequent message information when a paging signal matches its own paging number, operates a tone generator, and displays message information on a display. a group of switches; a memory circuit that stores data input by operating the switch group; a display drive circuit that displays the data stored in the memory circuit on a display according to a certain convention; and the memory circuit. and a DTMF signal generator that generates a DTMF signal corresponding to data stored in the sound generator and supplies the signal to the sound generator.

(Operation) The operation of the paging receiver with message sending function of the present invention having the above-mentioned configuration is as follows. First, its function as a paging receiver is similar to that of a conventional paging receiver capable of receiving messages. That is, when a paging signal is received, it decodes it, and if the result matches the paging number assigned to itself, it receives the subsequent message information, operates a tone generator, and calls the person carrying the receiver. At the same time, message information is displayed on the display.

Next, the message sending operation inputs message data by, for example, a combination of numbers or a combination of numbers and special symbols in the data input switch group according to a certain predetermined convention.

The input message data is temporarily stored in the memory circuit. The stored message data is converted by the display drive circuit into a form that can display the intended message and is sent to the display for display.

After confirming that the message content displayed on the display is as intended by the operator, the message data stored in the memory circuit is sent to the DTMF signal oscillator, and the message data is converted into a DTMF signal. converted.

This DTMF signal is then applied to a tone generator, which generates a DTMF signal tone. By transmitting this DTMF signal sound close to the transmitting section of the dial pulse telephone after dialing the area number and paging number of the paging terminal, the same effect as that of sending message data from the button telephone is obtained. become.

Thus, by using the paging receiver of the present invention, it is possible to send messages even from a dial-pulse telephone, and by utilizing the display function of the paging receiver,
It is possible to check whether a series of messages entered by a combination of numbers or special symbols contains any errors, and after confirming that there are no errors, to send them out all at once.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a paging receiver with a message sending function of the present invention.

First, the operation as a paging receiver will be explained.

The radio signal received by the antenna 11 is transmitted to the radio receiving section 1
, 2 and demodulated after amplification. The demodulated signal is sent to decoder 1
3, it is compared with its own paging number written in the ROM 14, and if it matches, the CP indicates that there is a call.
Report to IJ15.

The CPU 15 receives the message information following the paging number, and displays the LCD (Liqui-id
The message information is displayed on the Crystal Display (liquid crystal display) display 16, and the driver 1
A speaker 18, which is a tone generator, is sounded through the receiver 7 to notify the person carrying the receiver that there is a call. Furthermore, CP
U15 is operated by a clock generated by the crystal oscillator 23. The reset button 20 is used to reset sounds, display, etc.

Next, the function as a message sending device will be explained. By turning on the mode changeover switch 21, the paging receiver becomes capable of inputting/sending DTMF messages, and data can be inputted from the data input switch group 22.

When data is input, the CPU 15 stores the input data in an internal memory circuit (RAM) and displays it on the LCD display 6. Here, for example, as in the example in Table 1, a combination of multiple numbers or a special key (≠ or #
) and numbers to convert it into a certain character, it is displayed on the LCD display.

Table 1 Look at this display and if there is no error in the message, leave it as it is.
If there are any errors, correct them and press the reset button 2.
By pressing 0, a series of input information is output from the speaker 18 as a DTMF signal tone by one DTMF signal oscillator. For example, by having the function of clearing one character by pressing the "#" key once, and clearing all input data by pressing the "#" key twice, it is also possible to correct the input data in advance. 6 Next, we will discuss the operation of the CPU in more detail using Figure 2. A series of operation instructions for performing a series of processing operations is written in the program memory 1501, and the contents of the address corresponding to the program counter 1502 are stored in the control unit 150.
3, and based on this content, the control section 1503 sends control signals to each section. The program counter 1502 is normally incremented by +1 each time the contents of the program memory 1501 are sent to the control unit 1503, but when there is a jump command, etc., the program counter 1502 follows it.

The data bus 1506 is interfaced with external circuits by an input port 1507, an input port 1508, an output port 1509, an output port 1510, and an input port 1511.The data bus 1506 is connected to a program counter 1502. Data memory 1512, calculation unit (^rith
metie and LogicUnit> 1504
, and an accumulator 1505 to transfer and process data. Note that the crystal oscillator 23, the oscillation section 1515,
The timer 1514 is necessary for the processing of the CPU 15 and creates a lock.

The LCD control/driver 1513 as a display drive circuit is a control/driver circuit for displaying specific data on the LCD display 16 among the data stored in the data memory 1512. First, the reception operation will be explained.

When the decoder 13 detects a signal that matches the paging number written in the ROM 14, it generates a paging detection signal A, and at the same time sends a received signal B following the paging number and a synchronization signal C synchronized with the received signal to the CPU 1.
5, the CPU 15 receives the subsequent reception signal B as message information at the timing of the synchronization signal C through the input capacitor 1507, stores it in the data memory 1512, and sends the display signal E through the LCD control/driver 1513 to the LCD display. Output to 16. CPU16
At the same time, a sound signal is sent to the driver 17 through the output boat 1509, causing the speaker 18 to sound. Controls such as resetting the sound and LCD display are performed using the reset button 20 through the input board 1511.

Next, we will discuss its operation as a message sending device. By turning on the mode changeover switch 21, the CPU 15 knows through the input port 1511 that it is in a state in which it can manually send/send a DTMF message. In this state, by inputting data from the data input switch group 22, the CPU 15 temporarily stores the input data in the data memory 1512 through the input port 1508, and further sends out the display signal E through the LCD driver/controller 1513 and inputs it to the LCD display 16. Display the data. If there is an agreement in advance that a combination of multiple numbers or a combination of special keys and numbers will be converted into a certain character (or symbol), the converted character (or symbol) will be displayed on the LCD display. However, the data memory 1512
stores the input data before being converted.

When the data input is completed, by pressing the reset button 20, a series of input data is sent to the DT via the output boat 1510.
Activate the MF signal oscillator 19 and output DTM from the speaker 18.
F signal tone is sent out. At this time, if there is an arrangement for character conversion, the input data before conversion is sent out.

Of course, in this case, the same arrangement is required for the paging terminal. The specific way to use this paging receiver is to first enter the message you want to send to other paging receivers, then go off-hook from the dial pulse telephone and dial the area number of the paging terminal and the paging number of the person you want to call. .

Then, when the paging terminal is ready for message input (← when the message input ready signal is heard), the message data is sent by bringing the speaker of the paging receiver close to the transmitting section of the telephone and pressing the reset button.

FIG. 3 is a diagram explaining the above procedure.

FIG. 4 is an example of an external view of a paging receiver according to the present invention. Here, alphabets are also displayed on each display of the data input switch group to make the character conversion operation easier to understand.

Table 2 shows examples of character conversion.

It is the switch input that actually sends out the DTMF signal.

Table 2 Note that here, by turning on/off the mode selector switch 21, the reception status and DTMF message input/
Two functions that are ready to be sent are selected, but by simply inputting data using the data input switch group 22, storing it, and adding a function that allows you to read the input data at any time, you can memorize it. It can also be used as a book.

(Effects of the Invention) As explained above, the paging receiver of the present invention includes a data input switch group, an input data storage circuit, a display drive circuit, a display, a DTMF signal oscillator, and a sound generator. Since the message data input from the data input switch group can be output as a DTMF signal tone from the tone generator, it is possible to transmit the tone generator even from a dial pulse telephone, which normally cannot transmit message data. It has the advantage that by placing it close to the talk part, a DTMF signal tone can be sent to the paging terminal in the same way as a push-button telephone. Also, since it has a memory circuit and a display, it is possible to visually check whether the series of data entered from the data switch group by the combination of numeric keys and special keys is the message you intended. Messages can be sent out in batches continuously after confirming that there are no errors, and it is not possible to check for errors when inputting messages from a button button telephone, and the line can be used for the same amount of time as the button combinations are operated. By using the paging receiver of the present invention, there is an advantage that a reliable message can be sent in a short time using a line.
