DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for receiving and displaying a text message, and more particularly, to a DTMF signal (DTMF: Dual Tone Mult) corresponding to key figure character input.
(iple Frequency) when transmitting a text message, without using error notification or retransmission control, to receive and display a text message that enables the contents of the text message transferred from the sender to be recognized, and used directly for its implementation The present invention relates to a text message receiving / displaying device.

2. Description of the Related Art At present, telephones, which are the most widespread communication means, are used regardless of whether a communication network to be connected is an analog (telephone) line or a digital line (ISDN, etc.).
All the information transmission / reception (call) between the user, the exchange, and the communication partner is performed using signals in the voice band.

[0003] For this reason, a user who cannot recognize or transmit speech (such as a person who has a hearing or language impairment) can communicate with another recognizable medium (such as a picture or a character) using another communication device (such as a picture or character). FAX or modem). These communication devices are larger and more expensive than ordinary telephones.

[0004] For this reason, many healthy persons who can recognize and transmit voice are not in a state where they can always use these communication devices, and as a result, mutual communication between the two cannot be ensured. It is in.

[0005] In order to realize mutual communication between the two, it is necessary to transmit and receive information at a low cost and small size. One method for realizing this is to use a DTMF signal (a borrowing method corresponding to key figure character input). Character message transfer technology (recently, it is used when a simple telephone is used to easily send a character message to a pager center or the like from a normal telephone.
For example, it is conceivable to use JP-A-62-38039).

More specifically, a user who transmits a text message presses a numeric key button corresponding to a text message to be transmitted (according to a predetermined code system) after the call connection is completed, and presses it on the telephone. A DTMF signal corresponding to the inputted numeric key button is transmitted as a transmission voice. This is a function that most existing telephones already have.

[0007] On the other hand, the telephone on the receiving side (currently the center) of the text message receives the DTM extracted from the received voice.
It must have a function of recognizing the F signal and converting / displaying it into a corresponding text message, but these can be realized relatively inexpensively and compactly (for example, see Japanese Unexamined Patent Publication No.
No. 35656).

(First Method Example) Next, a first method example implemented by the text message receiving and displaying device 40 according to the first device example configured as described above will be described.

First, in this example of the method, the D which arrives at the telephone 30 from the opposite communication device 10 via the communication network 20
The voice communication signal including the TMF signal is transmitted to the receiving voice input means 4.
1 at the level of the analog received voice signal,
The DTMF signal recognizing means 42 recognizes and extracts the DTMF signal from the received voice signal, and sequentially outputs a series of key numeral characters corresponding to the DTMF signal.

The key numeric characters are stored in time series in the temporary storage means 43 to obtain a key numeric character string, and the required display format to be used for creating the character message display data in the display creating means 44 is displayed. A single character message display data, which is selectively designated by the format designation unit 45 from a plurality of types of display formats and obtained as described above, is displayed on the display unit 46.

The manner in which the display creating means 44 creates the character message display data from the key numeral character string is as described above.

Here, an example of the correspondence between the operation of the display format designating means 45 and the display of the display means 46 in the method example will be described with reference to the drawings.

FIG. 6 is a diagram showing a display example of the character message according to the first method example when the corresponding code that defines the correspondence between the key numeral character string and the character message is unknown, and FIG. It is a figure showing the example of a display of the character message concerned by the 1st example of a method, when a wrong press etc. occur.

First, as shown in FIG. 6, the sender (user of the opposing communication device 10) transmits, for example, a text message “Shiki FAX Hoshii” to an STD code (which is previously unknown to the receiving side). If the receiving side (user 50) performs reception according to a different coding system (for example, a DOCOMO code) when transmitting according to the system, the receiving side inevitably has garbled characters such as "Shikiyu EAT Hoshii". Is displayed on the display means 46 (FIG. 6).
Code table).

Here, the character message receiving and displaying device 40

Switching is performed in accordance with the designation of the display format, and the key numeral character strings stored in the temporary storage hand throw 43 are successively converted, and are sequentially displayed on the display means 46 and recognized by the user 50.

On the other hand, as shown in FIG. 7, when the sender transmits a text message “Shiki FAX Hoshii” in accordance with the DOCOMO code system in the same manner as in the above example, the sender presses a numeral (key). If an error is made or an error occurs during transfer, and the receiving side performs reception using the same DOCOMO code, the receiving side may have garbled characters such as "Shiyusashima U @ Nuka". The text message is displayed on the display means 46 (see the code table in FIG. 6).

In this case, even if the code is further switched using the display format designating means 45, the character message estimated to be correct is not displayed.
By switching the digit shift using 5, the user 50 can recognize the partially correct text message “K G SAX FAX Hoshi”, and consider this correct “U FAX Hoshi”. Is combined with a part of the character message "Shiki" in the case where the digit is not shifted, the character message "Shiki FAX Hoshii" considered to be correct can be recognized.

In other words, in accordance with the above operation of the user 50, the display creation means 45 switches the digit shift stage in the digit shift means 442 in accordance with the designation of the display format by the display format designation hand 44, and temporarily shifts. The key numeral character strings stored in the storage hand throw 43 are sequentially shifted by digits, and are sequentially displayed on the display means 46 to be recognized by the user 50.

The digit shifting means 4 of the display creating means 44
The maximum number of shifts (k) when sequentially performing the analysis shift at 42 is as follows: k = n- in the case of a code system in which one character message is represented by n key numeral character strings.
It may be set to 1.

Function.

With the division of the key numeral character string by the key numeral character string dividing means 47, the display format designating means 45 changes the display format of the character message display data for each of the two or more divided key numeral character string groups. The display creation means 44 creates character message display data parts of the display format designated by the display format designation means 45 for each of the two or more key numeral character string groups, and combines them to form a text message. The display data is created, and the display means 46 displays the character message display data created by the display creation means 44.

(Second Method Example) Next, a second method example performed by the text message receiving / displaying device 40 according to the second example of the apparatus configured as described above will be described.

First, in the present method example, the key numeral character string obtained by the temporary storage means 43 is divided into a plurality of parts by the key numeral character string dividing means 47, and two or more key numeral character strings are stored therein. The required display format to be obtained and used to create the character message display data is designated independently by the display format designation means 45 for each of two or more key numeral character string groups. The manner in which the display creating means 44 creates character message display data from two or more key numeral character string groups is as described above.

Here, an example of the correspondence between the operation of the display format designating means 45 and the display of the display means 46 in the method example will be described as follows. FIG. 13 is a diagram showing a display example of the character message according to the second method example when a key press error or the like occurs.

As shown in the figure, the sender, for example,
DO text message "Shikiyu FAX Hoshii"
When transmitting according to the COMO code system,
When the sender presses a wrong number or an error occurs during transfer, the receiving side first sets one key number character string dividing means 47 (key number character string group 1).
The operation is performed so as to divide (that is, only 3222831332716696953212) (that is, do not divide).

Here, the user 50 sets the display format of the key numeral character string group 1 to DOC by the display format designating means 45.
When the OMO code (with no digit shift) is selected, the display means 46 displays the text message display data of "Shiyusashima U @ Nuka" whose meaning is unknown, and the user 50 is garbled in the text message. Recognize that With this recognition, the user 50
When the digit shift is switched using the display format designating means 45, the display means 46 displays a character message "K G FAX FAX" which is considered to be partially correct.

Next, the user 50 sets two key numeric character strings (key numeric character string group 1 (322283) ) And key numeral character string group 2 (3132)
71669653212)), and further, for the key numeral character string group 1 and the key numeral character string group 2, the corresponding parts of the character message display data (“Shiki”)
And "U-FAX".

As described above, the display means 46
A character message "Shiki FAX Hoshii" considered to be correct is displayed (above, <Pattern 1>). Note that the user 50 can obtain the same display by another operation.

That is, at the boundary of the portion considered to be correct between the above two displays, the two key numeral character strings stored in the temporary storage means 43 (the key numeral character string group 1 (32228
33) and key numeral character string group 2 (1327166965)
3212)) (note that the division point is different from the above <Pattern 1>). Further, for the key numeral character string group 1 and the key numeral character string group 2 of this mode, both are DO.
Even if the display format of the COMO code (no digit shift) is specified, the same display can be obtained (above, <pattern 2>).

In other words, a digit (remainder digit) that seems to have an error is designated from the received key number character string, and the remaining digits are represented by a DOCOMO code (no digit shift). It is equivalent to displaying.

Therefore, when the transmitting side and the receiving side are used for an application in which an error occurs only by inserting or missing a digit, there is an error instead of switching the display code or the presence or absence of a digit shift. It is also possible to specify a digit (remainder digit) that is considered to be the one that has been deleted (automatically) and display it with a predetermined display code.

In the first example of the apparatus and the example of the method described above, the user 50 compares the two displays and stores them.
You needed to combine the right parts in your head, but in the example given here, you can see the text message that you think is actually correct on the screen (on display).

Also, here, an example has been described in which the display is once performed in each of the two modes and then the division is performed. It is needless to say that the present invention can be implemented by another operation mode, such as dividing the display into a normal part where no garbled characters are generated and displaying the divided part.

Further, for simplicity of explanation, an example has been shown in which, when an error occurs at one location, the character message display data is divided into two to obtain a correct display. Even if the number of text message display data needs to be divided into three or more due to an increase in the number, the same effect as described above can be obtained.

By the way, there are various examples of the user input interface for realizing the functions described above. FIGS. 14 to 17 which illustrate examples of four types of user input interfaces with reference to the drawings. FIGS. 14 to 17 show the first example applied to the second apparatus example and the method example of the present invention, respectively.
It is a figure which shows the example of the 4th user input interface.

First, as shown in FIG. 14, the user input interface 40a of the first example is for realizing the function of <Pattern 1> described above.
A code switching button 451 and a digit shift switching button 452 for designating a display format corresponding to the operation button 45a of the display format designation means 45 are arranged, and a division position designation corresponding to the operation button 47a of the key / numerical character string division means 47 is provided. Cursor button 471 and a confirmation button 472 are arranged.

Further, in the area of the LCD 46a of the display means 46, explanation position coordinates 46 indicating each digit of the key numeral character string are displayed.
1 and a cursor 462 for designating the digit of the key numeral character string are arranged.

Here, the user input interface 4
0a, first, the cursor button 47
By pressing 1, the cursor 462 is moved to the position where the division of the key numeral character string is desired (moving rightward as indicated by the arrow; "7" in the illustrated example).
By pressing, the division position is determined. As a result, the key number / character string dividing means 47
Are two key numeral character strings (in the illustrated example, the key numeral character string group 1 (“1” to
“6”) and key numeral character string group 2 (“7” to “2”).
2))).

Next, after using the cursor button 471 to move the cursor 462 to one of the cursor positions (for example, the position of “6”) included in the key numeral character string group 1, the code switching button 451 and the digit Shift switch button 4
52, a desired display format (DOC in the illustrated example) is used.
Select OMO code without digit shift).

Then, using the cursor button 471,
After moving the cursor 462 to any of the cursor positions (for example, the position of “7”) included in the key numeral character string group 2, a desired display format (using the code switch button 451 and the digit shift switch button 452) is used. In the illustrated example, DO
COMO code with digit shift)
As described above, the character message considered to be correct is displayed (the display of the key numeral character string group 1 at this time is not an object of the current selection, and thus remains in the state without digit shift of the DOCOMO code).

On the other hand, the user input interface 40b of the second example shown in FIG. 15 is for realizing the function of <Pattern 1> similarly to the above-described example, and the number of buttons on the panel surface is designed. This is an example in which the functions of the code switching button 451 and the digit shift button switching button 452 described above are integrated into one display format selection button 453 when it is necessary to reduce the number of buttons.

The user input interface 40c of the third example shown in FIG. 16 is for realizing the function of <Pattern 2>. Further, the user input interface 40c of the fourth example shown in FIG. The interface 40d is for realizing a function of deleting a digit (remainder digit) in which an error has occurred.

The operation and operation method of the user input interfaces 40b, 40c and 40d in the second and subsequent examples are described in the first example.
Since these are basically the same as those in FIG.

(Third Device Example) Next, a third device example will be described. FIG. 18 is a block diagram showing a circuit configuration of the text message receiving and displaying device according to the third embodiment of the present invention.

As shown in the figure, the text message receiving device 40 according to the third device example converts a voice call signal including a DTMF signal arriving at the telephone 30 from the opposite communication device 10 via the communication network 20, A receiving voice input means 41 for inputting at a level of an analog receiving voice signal, and a DTMF signal recognized and extracted from the receiving voice signal input to the receiving voice input means 41, and a series of key numeral characters corresponding to the DTMF signal Signal recognition means 42 for sequentially outputting
And a temporary storage unit 43 that stores the key numeral characters output from the DTMF signal recognizing unit 42 in time series to obtain a key numeral character string, and a key numeral character string obtained by the temporary storage unit 43. Display creation means 44 capable of creating text message display data for restoring and displaying text messages in a plurality of types of display formats; and a plurality of (first to fourth) text messages created by the display creation means 44 Display means 4 for simultaneously displaying all of the display data
6.

That is, the character message receiving / displaying device 40 of the third device example removes the display format designating device 45 from each component of the first device example described above, A function to constantly create first to fourth character message display data 1 to 4 having different display formats is provided, and these four character message display data 1 to 4 are provided in correspondence with the display means 46. The first to fourth LCDs 46b to 46e are simultaneously displayed.

(Third Method Example) Next, a third method example implemented by the text message receiving and displaying device 40 according to the third device example configured as described above will be described.

First, in this example of the method, the D which arrives at the telephone 30 from the opposite communication device 10 via the communication network 20
The voice communication signal including the TMF signal is transmitted to the receiving voice input means 4.
1 at the level of the analog received voice signal,
The DTMF signal recognizing means 42 recognizes and extracts the DTMF signal from the received voice signal, and sequentially outputs a series of key figure characters corresponding to the DTMF signal. The key number character string is obtained.

Further, the display creating means 44 converts the key numeral character string into a four-character
A plurality of types of character message display data 1 to 4 are displayed in a plurality of types of display formats (for example, there is no digit shift of the DOCOMO code, digit shift of the same DOCOMO code, no digit shift of the STD code, and digit shift of the STD code). 4 types of display formats), and these are simultaneously displayed on the first to fourth LEDs 46b to 46e of the display means 46.

Here, a display example of the display means 46 in this method example will be described with reference to the drawings. FIG. 19 is a diagram illustrating a display example of the character message according to the third example of the method when the correspondence code that defines the correspondence between the key numeral character string and the character message is unknown.

As shown in the figure, the sender, for example,
ST text message "Shikiyu FAX Hoshii"
When transmission is performed according to the D-code (the correct display format is unknown on the receiving side) and no error or the like occurs during the transfer, the display creating means 4 on the receiving side.
4, the “DOCOMO code (without digit shift)”, “DOCOMO code (with digit shift)”,
Character message display data 1 to 4 based on four types of display formats, “STD code (without digit shift)” and “STD code (with digit shift)” are created.

These are simultaneously displayed on the first to fourth LCDs 46a to 46e of the display means 46, respectively. As a result, the user 50 sees each displayed text message, and the transmitted text message forms an STD code system (no digit shift, that is, no error occurs during transmission). And the content of the message is "Shikiyu FAX Hoshii"
Can be recognized.

(Fourth Device Example) Next, a fourth device example will be described. FIG. 20 is a block diagram showing the circuit configuration of the text message receiving and displaying device according to the fourth embodiment of the present invention.

As shown in the figure, a text message receiving device 40 according to the fourth device example includes a telephone 30 used.
Is a digital telephone (30), and a connection interface between the digital telephone 30 and the communication network 20 in place of the various receiving voice input means 41 shown in the first to third device examples. Receiving voice signal converting means 48 for collecting digital receiving voice signals transmitted in parallel from the communication network 20 to the main body of the digital telephone 30 and then converting the digital receiving voice signals to required analog levels. And the DTM at the next stage
The F signal recognizing means 42 receives the received voice signal converting means 48
The DTMF signal is recognized and extracted from the received voice signal of the analog level converted in step (1).

Here, the receiving voice signal converting means 48 is, in detail, provided on a transmission line via a communication line interface section 48a (layer 1 communication line interface function) corresponding to the form of the communication network 20 (line). A digital reception voice signal is extracted from the electric signal, and further, a decoding unit 48b
(Decoding function including D / A conversion) creates a required analog reception voice signal.

The communication line interface 48a
Can be realized using, for example, a commercially available communication line (layer 1) interface component (LSI), and a commercially available CODEC component can be used for the decoding unit 48b.

(Fourth Method Example) Next, a fourth method example performed by the text message receiving / displaying device 40 according to the fourth example of the device configured as described above will be described.

In this example of the method, the premise is that the digital telephone 30 is used to input the received voice signal at the analog level, but the communication line interface unit 48a of the received voice signal converting means 48 first uses the digital line 30 to input the received voice signal. After collecting the digital reception voice signal transmitted on the wiring leading from the communication network 20 to the main body of the digital telephone 30, the decoding unit 48b converts the signal into a required analog level.

Here, with respect to the above-described embodiment, an example of the present apparatus will be described.
A specific description will be given of an example in which the digital telephone 30 is used in combination with a digital telephone 30 connected to an ISDN basic interface communication line (ISDN: integrated service digital network).

Generally, in the ISDN basic interface, transmission (TA line, TB line) and reception (RA line, RB line) are performed between the communication network 20 (including the line terminating device) and the digital telephone. An electric signal of 192 Kbps is transmitted using one pair (two) of cables.

To extract a required digital reception voice signal from the reception cable (wiring),
The receiving voice signal converting means 48 uses a component having a function of the layer 1 interface of the communication line (defined by the I.430 recommendation of the ITU-T (International Telecommunication Union / Telecommunication Standardization Sector)). A digital reception voice signal on the B channel (64 Kbps) during voice communication is obtained.

This digital received voice signal is based on ITU
G of -T. Rule defined in Recommendation 711 (μ-law)
, The corresponding COD
By performing decoding and D / A conversion processing of a digital received voice signal using a component having an EC function, an analog received voice signal can be extracted.

Although the description has been made here assuming that the communication network 20 includes the line terminating device, a necessary communication line (layer 1) is also provided above the line terminating device (between the exchange and the line terminating device). The interface function is based on ITU-T It is needless to say that the same processing can be performed only by the one specified in the Recommendation No. 961 and an analog reception voice signal can be created.

In addition to the above-described ISDN, the communication line interface unit 4 is also used for other digital communication lines that do not directly transmit analog reception voice signals, such as digital leased lines and business phone extensions.
It is needless to say that by using the one corresponding to the communication line as the 8a and the decoding unit 48b, the creation of the required analog received voice signal can be similarly realized.

As described above, the embodiments of the present invention have been described with reference to the first to fourth examples of the apparatus and the first to fourth examples of the methods corresponding thereto. However, the present invention is not necessarily limited to the above-described method. However, the present invention can be appropriately changed and implemented within a range that achieves the object of the present invention and has the effects described below.

For example, in the present embodiment, all functions of the text message receiving / displaying device 40 are described as being independent of the telephone 30, but the text message receiving / displaying device 40 is built in the telephone 30, It goes without saying that both functions can be shared.

More specifically, the receiving voice input means 41 can be made simpler, and the display format designating means 44 also serves as various operation buttons of the telephone 30, and the temporary storage means 43 and the display The creator 45 also serves as a microcomputer for controlling the man-machine interface of the telephone 30,
It is conceivable that the display means 46 is realized by also using an LCD for dial display or the like.

The DTMF signal recognizing means 42 also receives the DTM signal from the mouthpiece (portion for the mouth) of the handset 32.
If the telephone 30 is provided separately for F input recognition, it can be switched and used.

[0124]

As described above, according to the present invention, when a text message is transmitted by a DTMF signal, the corresponding code between the DTMF borrowed character and the character used by the transmitting side is unknown, or the key input by the sender is incorrect. Even if garbled characters occur, the receiving side switches multiple corresponding codes and converts them to a character message, or shifts the digit of the key figure character string and converts it to a character message and displays it Therefore, it is possible to recognize the contents of the text message transferred from the sender without performing time-consuming error notification and retransmission control.

Further, according to the present invention, it is possible to display the contents of a text message by a DTMF signal in an extremely simple form, and at the same time, the recipient can intuitively and easily recognize the contents of the text message. It is also possible to do.
