Description

Communication method and communication terminal device

The present invention relates to a communication terminal device and a communication method which can be connected to a computer communication network such as, for example, the Internet.

In general, communication with a facsimile apparatus is often performed through a public line network.

However, the cost required for such facsimile communication increases in proportion to the distance between the communication states.

In recent years, computer communication networks such as the Internet have become widespread. By using this computer communication network, it is possible to communicate with a communication terminal not only in Japan but also in foreign countries by only paying a communication cost to the nearest contract provider (connection provider of the computer communication network).

For this reason, by performing communication using a computer communication network, the cost especially required for long-distance communication can be reduced.

The facsimile communication is generally performed by the circuit switching method. That is, the facsimile apparatus on the transmission side establishes a communication line directly with the facsimile apparatus on the transmission side by the circuit switching method, and then performs image data and transmission. Therefore, the receiving facsimile apparatus can immediately print out the received image data when the image data is received, and the user on the receiving side can immediately know that the data is being received.

In contrast, when an electronic mail is transmitted using a computer communication network, generally, the reception side is not actively notified that the electronic mail has been sent.

That is, a user using a computer communication network can know that e-mail has been received by connecting the communication terminal to the computer communication network by dial-up. Therefore, even if the sender sends an e-mail to the computer communication network, the receiver cannot immediately know that the e-mail has been sent to him or her.

For this reason, the user of the computer communication network has to dial up at an appropriate time (for example, at the time of mail) and check whether or not the e-mail is arriving, and the operation is complicated. In addition, on the sending side, when it is desired to immediately notify the receiving side of the contents of the electronic mail, it is sometimes necessary to inform the receiving side of the meaning of the transmission of the electronic mail by telephone, fax or the like.

In a computer communication network, there may be cases in which a plurality of computers may be used until an e-mail arrives from the sender to the recipient, and some delay delivery may occur depending on the amount of data and the congestion of the line.

The facsimile communication procedure and communication method of G3, G4 and the like are different from those of the computer communication network, and therefore, the facsimile apparatus cannot be directly connected to the computer communication network.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to promptly inform the receiving side of the fact that an e-mail has been sent to the computer communication network, and furthermore, on the receiving side in accordance with an instruction from the transmitting side, the computer communication network. The present invention provides a communication method and a communication terminal apparatus capable of receiving e-mail from a network.

It is also an object of the present invention to provide a communication terminal apparatus capable of receiving electronic mail by knowing that the electronic mail has been delivered on the receiving side promptly even when delayed delivery of electronic mail occurs in a computer communication network. will be.

It is also an object of the present invention to provide a communication terminal apparatus capable of transmitting image data obtained by reading and scanning a document as an electronic mail and outputting the image data of the received electronic mail.

(1) CPU comprising a mail sending means, a mail receiving means, a request signal sending means, and a request signal receiving means.

(6) ROM comprising the mail sending means, mail receiving means, request signal sending means, request signal receiving means;

(7) RAM comprising a mail sending means, a mail receiving means, a request signal sending means, and a request signal receiving means.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment which actualized this invention is described using drawing.

In this embodiment, the image data is transmitted as an e-mail, and the Internet is used as the computer communication network.

As shown in Fig. 1, the communication terminal device T has a function for communicating with the Internet in addition to the G3 and G4 facsimile communication functions.

The CPU 1 controls each part of the communication terminal device T via the bath 13, and also encodes, decodes, image-converts, text-converting, mail editing, and number of operators to be described later. Run the software for processing.

The reading unit 2 reads an original image by a CCD (Charge Coupled Device) or the like. Outputs two values of black and white image data. The recording unit 3 includes a printer such as an electrophotographic method, and records image data received from another G3 or G4 facsimile apparatus or the Internet on a recording sheet.

The display unit 4 made of an LCD (Liquid Crystal Display) or the like displays the operation state of the communication terminal device T and the image data. The operation unit 5 is provided with a den key, a single speed dial key, a one touch dial key, various types of yellow keys and the like required for operating the communication terminal device T. FIG. The ROM (Read Only Memory) 6 stores software required for the operation of the communication terminal device T. RAM (Random Access Memory) 7 is composed of SRAM (Static Random Access Memory) or fret memory (FRESHEEEEP: Flash Electrically Erasable Programmable Read Only Memory), etc., to store temporary data generated when the software is executed. In addition to the storage, various tables T1 (T2) and T3 (see Fig. 3) described later are stored.

The image memory 8 is composed of a DRAM (Dynamic Random Access Memory) or the like, and temporarily stores image data to be transmitted or received image data.

The TA / DSU (Terminal Adapter / Digital Service Unit) 9 is connected to the digital line Ll. Data transmitted on the digital line Ll is transmitted according to the baseband transmission method.

For this reason, the TA / DSU 9 converts the transmission data as a digital signal into a change in voltage, is sent out on the digital line Ll, and also converts a voltage change on the digital line Ll into a digital signal as reception data.

The modem 10 modulates and demodulates transmission / reception data, and has a data modem function in addition to the conventional FAX modem function.

The network control unit (NCU) 11 closes and opens the analog line L2, and has a function of detecting transmission and reception of dial pulses corresponding to the other party's fax number.

The timer 12 is provided to measure time.

The operation of the timer 12 will be described later, but the time set by the key operation of the operation unit 5 is measured.

Fig. 2 schematically shows the flow of data in the communication terminal device T in this embodiment.

And. In the figure, the encoding decoding unit 21, the image conversion unit 22, the binary, the text conversion unit 23, the mail editing unit 24, and the autodial 25 have the CPU 1 in the ROM 6; It displays the function to execute according to the stored software.

The encoding and decoding unit 21 encodes or decodes the image data by an encoding method such as an MH (Modified Huffman) method, an MR (Modified READ) method, or an MMR (Modefied MR) method. Hereinafter, the image data encoded by these coding methods is called "G3 format image data."

The image memory 8 stores this G3 format image data.

The image converting unit 22 converts the G3 format image data to TIFF (Tag Image File Format), which is a general image format used in a computer when transmitting, and converts TIFF to G3 format image data upon reception. do. Here, TIFF is a standard format of an image file proposed by Aldus, Inc. (currently, merged with Adobe Systems), and does not specify a standard data format. The attribute of image data is used as TAG (tag) information. It is characteristic that it prescribes. For this reason, in the TIFF format, the format of the data can be recognized by reading standardized tag information described in hundreds of bytes of all the image files.

In addition, TIFF has become a family of various classes dealing with not only two hulls but also white hulls, glues and the like. One of them, ClassF, defines image data in G3 format. therefore. TIFF can be converted by adding TIFF header information of ClassF to the head of G3 format image data. Hereinafter, G3 format image data to which ClassF TIFF header information is added is called "TIFF image data."

The binary and text conversion unit 23 converts the binary data into list data at the time of transmission, and converts the text data into binary data at the time of reception. Since there are computers that cannot handle binary data e-mail on the Internet, when binary data such as TIFF image data is transmitted to reach the other party reliably, it is necessary to convert it into text data. . Text data handled on the Internet is defined as a 7-bit code in RFC (Request For Comments) 822, a document issued by the IETF (Internet Engineening Task Force).

Thus, the binary and text conversion unit 23 converts data using a base 64 of MIME (Multipurpose Internet Mail Extensions) or the like. According to this base 64, 6-bit binary data can be converted into text data by replacing one of (64) characters (uppercase and lowercase alphanumeric characters, numbers, +, /) and (2) for barding. . MIME is defined in RFC1521 (defined in MIM7E header), RFC1522 and RFC1590.

The mail editing unit 24 adds the mail header information to the TIFF image data converted into text data to be edited in an e-mail format, and removes the mail header information from the e-mail format data when receiving the text data. Extracts only the TIFF image data converted into. Since predetermined header information is added to the e-mail on the Internet, at the time of transmission, the head of the TIFF image data is displayed in accordance with the data in the counterpart table T1, the user table T2, and the like, as shown in FIG. Add items such as "From", "To", "Subject", "Cc", "Date", and so on.

The autodial 25 calls the other party's phone to the TA / DSU9, the modem 10, or the NCU 11 to call the telephone number read from the counterpart table T1 and the provider table T3 in the RAM 7. Send number data.

Next, each of the tables T1, T2, and T3 stored in the RAM 7 is clear using FIG.

As shown in Fig. 3A, the counterpart table T1 registers data of the counterpart name, Internet e-mail address, facsimile number and facsimile type (G3 or G4) for each address number or one-touch dial key. have.

As shown in Fig. 3B, the user (sender) table T2 includes a user name of the communication terminal device T, a user ID for logging in to the Internet, a password, an Internet e-mail address, a provider. Type data is registered.

When a plurality of users share one communication terminal device in a business office or the like, each of the above data may be registered for each user, and data may be selected according to the user at the time of transmission.

As shown in Fig. 3 (c), the provider table T3 contains data of the telephone number, line type (analog or digital line), provider name, and provider type of the provider used when connecting to the Internet. It is registered.

The provider type corresponds to the provider type of the user table T2, and is for identifying different login procedures for each provider. It is also possible to register each of the above data for each telephone number, such as when one provider has a plurality of telephone lines or when a user uses a plurality of providers, and select the data necessary for transmission. .

Next, the procedure for sending an e-mail to the Internet will be described.

The communication protocol uses the one in Table 1 for each filling of the Open System Interconnection (OSI) reference model.

Here, SMTP (Simple Mail Transfer Protocol) will be described. SMTP is one of the protocols and protocols of TCP / IP, and is a protocol for sending to any user of a text format e-mail. According to this SMTP, mail can be transmitted reliably and efficiently. This SMTP is specified in RFC822.

Next, the login procedure will be described. As shown in Fig. 4, when the communication terminal device T is set with a line of a provider computer (hereinafter referred to as Sabah), for example, the user terminal and the password are supplied in accordance with PAP (Password Authentication Protocol). Transmission is continued until an "ACK" (Acknowledge. Acknowledgment) or "NAKJ (Negative Acknowlege)" is received.

"When NAKJ is received, the number of retries set by the protocol is set. If all of them are" NAKJ, the line is opened once and then redialed. "

When the ACK is received, the login of Sabah is completed.

After the login of Sabah is complete, as shown in FIG. Send e-mail by SMTP.

That is, first, the communication terminal device T requests the connection of SMTP to Sabah. If Sabah can connect, the response code "220" (Sabah ready) is returned to the communication terminal device T. In addition, if the communication terminal device T transmits its own domain name from the "HELO" codando and Saba can recognize the domain name of the communication terminal device T, the response code "250" (requested Return the commando to normal) and Sabah's Demain name. Thereafter, the communication terminal device T transmits the mail, and when the transmission is completed, transmits the "QUIT" commando. As a result, when Saba returns the response code "221" (connected crot (response to QUIT)), SMTP ends. After completion of the transmission of the e-mail, the communication terminal device T logs off from Sabah and opens the line.

Next, the operation in the case where the communication terminal device T of the present embodiment becomes the transmitting side will be described according to the flowcharts of FIGS. 6 and 7. The operations performed by the user are displayed from S1 to S4, and thereafter, the processing executed by the CPU 1 in accordance with the software stored in the ROM 6 is displayed.

As shown in Fig. 6, first, the user sets an original to be transmitted on a transmission table (not shown), and then (S1), inputs a pass code by operating the operation unit 5 (S2). By inputting this passcode, the communication terminal device T selects a user name indicating a user corresponding to the passcode from the user table T2. The user name is specified by the pass code to prevent unauthorized use by others. This passcode can also be used as a password for connecting to the Internet.

Next, the user selects the provider or line to be used by key operation of the operation unit 5 from the provider table T3 (S3).

Next, the user presses a start key (not shown in the figure), followed by a shortcut number or one-touch key corresponding to the transmitting party (S4). As a result, in the communication terminal device T, the transmission partner is selected from the counterpart table T1.

Next, the originals of the document glass are read out one by one from the reading unit 2, and once the read data for all the pages is encoded by the encoding decoding unit 21, for example, by the MMR method, as image data in G3 format. Accumulated in the image memory (S5).

However, since the image data cannot be sent directly from the Internet, it is converted into an e-mail format as follows. First, the header information of TIFF ClassF is added to the head of the G3 format image data by the image conversion unit, and TIFF image data is created (S6).

Since the TIFF image data is binary data, the TIFF image data is converted into a text generator by the binary decode conversion unit (S7).

Subsequently, in the mail editing unit 24, a header of the e-mail is added to the TIFF image data converted into the dex data. As shown in Fig. 10, the header includes at least items of "From", "To:", and "Subject:".

In "From:", the Internet e-mail address of the user selected in the user table in S2 is shown. In "To:", the Internet e-mail address of the other party selected in the other party table T1 in S4, and in "Subject:" "TIFF (G3)", which indicates that it is an e-mail containing image data in TIFF format, is set (S8).

When the e-mail format data is completed, Internet dial-up connection is made (S9 to S13). That is, according to the provider table T3, the type (analog / digital line) of the line of the provider selected in S3 is determined (S9), and if it is an analog line, the modem 10 is set (S10). . If it is a digital line, TA / DSUg is set (S11). Then, according to the provider table T3, it is sent to the telephone number of the selected provider (S12), and a response is awaited (S13).

When the telephone line of the provider is set, the user is logged in according to the above-described PAP, and an e-mail is transmitted by SMTP (S14).

After the transmission is completed, the user is logged off and the telephone line is opened (S15).

Next, it is determined whether or not there is a time setting of the timer 12 (S16). If there is no setting, S18 of FIG. 7 is performed as it is. If there is a setting, it waits for a predetermined time (for example, 10 minutes) set in advance from the opening of the line mentioned above (S17). After a predetermined time elapses, S18 of FIG. 7 is performed.

In S18 of Fig. 7, the facsimile type (G3 / G4) of the counterpart selected in S4 is determined (S18). If G3, modem 10 is set (S19). If G4, TA / DSU9 is set (S20). Then, according to the counterpart table T1, a call is made to the facsimile number of the selected counterpart (S21).

When the line is set in response to the partner facsimile apparatus (S22), various facsimile control signals are exchanged with the counterpart facsimile apparatus (S23). The non-standard facilities set-up (NSS) signal is included in the facsimile control signal transmitted to the other party. This NSS signal includes information (request request information) indicating the request to receive the e-mail sent first, the Internet address of the sender of the e-mail, and the Internet e of the user selected in S2. Mail address and facsimile number data are stored.

Next, a transmission notice as shown in Fig. 11 is transmitted in the G3 or G4 sequence (S24), and after completion of transmission, the line is opened (S25). This transmission notice describes the transmission of an e-mail.

Next, the operation in the case where the communication terminal device T of the present embodiment becomes the receiving side will be described according to the flowcharts of Figs. 8 and 9. This operation is executed by the CPU 1 in accordance with the software stored in the ROM 6.

As shown in Fig. 8, if there is a facsimile reception from the transmitting side (S31). In the received NSS signal, it is judged whether or not there is information (request request information) indicating the request to receive the e-mail (S32). If the request information of the reception is stored in the NSS signal, the e-mail is sent. It is determined that it is necessary to receive, and the process proceeds to S33. If the reception request information is not stored, it is determined that the normal facsimile communication is completed, and the processing ends. When the reception request signal is stored in the NSS signal, the transmission notice shown in Fig. 11 is received and recorded on the recording paper by the cyclical reception in S31. In S33, it is determined whether or not there is a time setting of the timer 12. If no timer is selected, the routine proceeds to S35. If there is a timer setting, elapse of a predetermined time (for example, 10 minutes) preset from the end of the above-described facsimile reception is waited. After a predetermined time elapses, the process proceeds to S35.

In S35, the user table T2 and the provider table T3 are referred to according to the Internet e-mail address of the transmitting party (i.e., the user of the communication terminal device T on the receiving side) displayed among the received NSS signals. By doing so, the provider and type (analog / digital line) are determined (S35).

Here, if the provider is an analog line, the modem 10 is set (S36), and if it is a digital line, TA / DSU9 is set (S37). Then, the telephone number of the selected provider is called (S38), and a response is awaited.

When the telephone line of the provider is set, after the logo is made in accordance with the above-described PAP (S40), it is determined whether or not the incoming mail reaches the provider (S41).

If there is no e-mail in the provider, once the line is opened (S42), after a predetermined time lapse, the process returns to the above-described S34 so as to receive the e-mail again. If the provider has e-mail, the process proceeds to S43 in FIG. In S43, an e-mail in the provider is received and recorded on the recording sheet by the recording unit 3 (S44). In this recording, the received e-mail is converted into T3 format image data and recorded. If the received e-mail is not converted to G3 format image data, only the header information is recorded.

The provider may also receive e-mail from a partner other than the one displayed in the NSS signal received during the first facsimile communication. Therefore, if there is an e-mail in the provider, when the e-mail is received, the other side of the Internet e-mail address displayed in "From" in the header information of the e-mail and the NSS signal received first is displayed. If the e-mail addresses are compared and the compared addresses do not match, it is determined by the facsimile communication that it has not yet reached the provider of the e-mail requested to be received, and the flow returns to S34.

In this way, the electronic mail requested to be received by the facsimile communication can be reliably received.

Thereafter, it is determined whether or not there is a setting for sending a receipt notice by e-mail (S45). If there is a setting, the receipt notice is sent by e-mail (S46), and after completion of the transmission, the line is opened (S47). Exit.

If there is no setting for sending a receipt notice by e-mail, after the line is opened (S48), the other party's facsimile type G3 / G4 is determined according to the other party table T1 (S49). If G3, modem 10 is set (S50), if G4, TA / DSU9 is set (S51), and the call is made to the other party's facsimile number (S52).

When the other party's facsimile apparatus responds, the line is established (S53), and a receiving notice as shown in Fig. 12 is transmitted in G3 or G4 order (S54), and the line is opened after the transmission is completed (S55).

And. This receipt informs you of the receipt of your e-mail.

As described above, in the present embodiment, the following actions and effects can be obtained.

(1) After the e-mail is sent to the Internet, it is notified to the receiving party by fax of the transmission notice by facsimile communication. Further, in facsimile communication, information requesting a request to receive an e-mail is transmitted to the receiving side. In other words, the NSS signal is transmitted as a reception request form indicating a request to request reception of an electronic mail. In addition, facsimile communication is performed by circuit switching.

For this reason, it is possible to immediately notify the receiving side that the e-mail has been transmitted, and the receiving side can automatically and immediately receive the e-mail before the user from the provider in accordance with the reception of the NSS signal.

(2) Only information indicating the meaning of sending an e-mail is known by facsimile communication, and the actual contents of the e-mail are transmitted via the Internet. Can be suppressed.

(3) When the sent e-mail is received at the receiving end, a receiving notification company indicating the received meaning is automatically sent to the sending side of the e-mail by e-mail or facsimile communication. You can be sure that you are reaching or not.

(4) Since image data used for facsimile communication is exchanged with text data, even image data read on a document can be transmitted reliably via the Internet as an e-mail.

(5) On the Internet, after an e-mail is sent through a plurality of computers, depending on the amount of data, line congestion, etc., the e-mail is contracted at the receiving end. This can cause a delay until the provider is reached.

However, in this embodiment, the transmission side can set a time difference between sending an e-mail and setting a facsimile transmission by setting the timer 12.

Therefore, in consideration of the time when the e-mail arrives at the provider contracted by the receiving side, the receiving side can be requested to receive the e-mail. Therefore, on the receiving side, even if the provider dials up to the provider in response to a request by the facsimile communication from the transmitting side, the e-mail can be reliably taken out from the provider.

On the receiving side, by setting the timer 12, the time difference can be set from the facsimile reception until the dial up to the provider. For this reason, it becomes possible to start taking out the e-mail in consideration of the time when the e-mail from the sending side reaches the provider. Therefore, when dialing up to a provider in response to a request by facsimile communication from the transmitting side, an e-mail can be reliably taken out from the provider.

The timer 17 may be set on at least one of the transmitting side and the receiving side.

The timer 12 is set based on the distance of the other party. For example, the setting time can be changed by country code or city code.

(6) When the e-mail from the sender still does not reach the provider when dialing up to the provider, the e-mail requested to be received from the sender is automatically dialed up after a predetermined time elapses. You can receive mail more reliably.

(7) It is convenient to set the transmission mode at the time of receiving notification by e-mail or facsimile communication at the user's request.

In addition, the said embodiment may be changed as follows, and in that case, the same action and effect as the above-mentioned embodiment can be acquired at least.

(a) Instead of TIFF format, you may convert to BMP (Bitmap) format, JPEG (Joint Photograhic Experts Group) format, GIF format, EPS format IFF format, or PICT format. Also, facsimile image data such as MH and MR are transmitted as is without changing to the TIFF format.

(b) In S43 of Fig. 9, the received e-mail is displayed on the display section 4 instead of recording on the recording sheet.

(c) sending the e-mail to the Internet after notifying the information of requesting the receipt of the e-mail by facsimile communication, in this case, after receiving the request of receiving the e-mail on the receiving side. In consideration of the time until the e-mail arrives at the provider, it is necessary to set the time by the timer 12.

(d) Sending an e-mail to the Internet and requesting an e-mail reception by facsimile communication. In this case, it is necessary to use two lines at the same time. Therefore, a digital line Ll and an analog line L2 are used. Used for the Internet and fax. By simultaneously performing transmission of electronic mail on the Internet and facsimile communication, the processing time of the entire communication terminal device T can be shortened.

(e) Sending data other than the image data of two black values to the Internet by e-mail, for example, sending image data such as black two values and color as TIFF image data, in this case, transmitting data to TIFF. Instead of the format, you may convert to BMP (Bitmap) format, JPEG (Joint Photograhic Exfperts Group) format, GIF format, EPS format, IFF format or PICT format. In addition to data other than image data, such as audio and video. Request to receive an e-mail can be made by facsimile communication.

(8) Using computer networks other than the Internet.

(9) Instead of the NSS signal, the specific DTMF (Dual Tone Multi Fregnency) is used as an e-mail reception request signal.

Since this invention is comprised as mentioned above, the following effects are exhibited.

The sending side not only sends the electronic mail to the computer communication network, but also notifies the receiving side that the electronic mail has been sent to the computer communication network, so that the receiving axis can quickly know that the electronic mail has been sent.

In addition, the transmitting side transmits an e-mail to the computer communication network and transmits a signal indicating a request to receive the e-mail, and the receiving side receives a signal indicating to request the reception of the e-mail. Since the e-mail is received from the e-mail, the e-mail can be received quickly.

Even if the wiring of the electronic mail of the computer communication network may be delayed, since a reasonable time margin can be secured between the transmission of the electronic mail on the sending side and the reception of the electronic mail on the receiving side, the receiving side Even if you want to receive an e-mail at, you can avoid the situation that it is not wired yet.

In addition, since the original can be read and sent as an e-mail, and image data can be visually output from the received e-mail, the original can be transmitted and received like a facsimile.

Even if a large number of manuscripts may be sent to remote locations such as overseas, they can be sent to the computer communication network as e-mail, thereby paying for the communication cost, and also promptly transmitting the e-mail to the receiving side. Can be received.
