Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication network system having a service function for distributing electronic mail such as Internet mail and a message unique to a communication carrier, and a terminal device used in this system.

[0002]

2. Description of the Related Art Generally, computer network systems and some mobile communication network systems are provided with a service function for distributing electronic mail such as Internet mail and messages unique to a communication carrier.
It is also planned to provide an e-mail distribution service function in a next-generation mobile communication network system that will start operating in the near future.

[0003] An electronic mail distribution service in a mobile communication network system is performed, for example, as follows. That is, the e-mail created in the transmitting portable terminal is transferred from the portable terminal to the mail server via the mobile communication network and stored. Note that an attached file can be attached to the e-mail.
Upon receiving the e-mail, the mail server sends an incoming call notification to the destination portable terminal. This incoming call notification is displayed on the mobile terminal. When the user of the portable terminal on the receiving side performs an e-mail acquisition operation in response to the incoming call notification, an e-mail download request is sent from the portable terminal to the mail server. The e-mail is downloaded and displayed on the mobile terminal.

[0004] When this electronic distribution service function is used,
For mobile terminal users, information can be transmitted by e-mail from anywhere at any time regardless of the situation of the communication partner, which is very convenient.

[0005]

However, in general, in a terminal having an e-mail receiving function, when an e-mail is received, first, header information is displayed, and then the main body of the e-mail is displayed. If there is an attached file, the receiving user performs the attached file display operation, and the file is executed for the first time and the information is displayed. For this reason,
In any case, in order to execute the attached file, the recipient user had to manually operate each time, which was extremely troublesome.

Further, as described above, the execution form of each component such as header information, text, and attached file constituting the electronic mail, that is, the display order and its display format are always constant regardless of the type and content of the electronic mail. It is. For this reason, for example, even if the transmitting user has a desire to notify the information of the attached file to the receiving user before the text,
This is not realized unless the receiving user performs the operation intentionally, and as a result, the use of the attached file has to be limited.

The present invention has been made in view of the above circumstances, and its main purpose is to execute a component of an e-mail on a receiving terminal in an arbitrary form according to a request of a transmitting terminal user. It is an object of the present invention to provide a communication network system and a terminal device thereof, which make it possible to expand the use of the attached file.

[0008]

In order to achieve the above object, a communication network system according to the present invention is provided with a mail transmission control means in a terminal device on a transmission side, and an electronic mail comprising a plurality of components including an attached file. When composing and transmitting an e-mail, control information for designating a reception execution mode of each component of the e-mail is inserted into a specific component other than the attached file of the e-mail and transmitted. On the other hand, the terminal device on the receiving side is provided with mail reception execution control means, and when receiving and executing an e-mail addressed to itself, extracts control information from a specific component of the e-mail and extracts the extracted information. The receiving execution form of each component of the electronic mail is variably controlled based on the control information.

Therefore, according to the present invention, the transmitting user inserts the control information designating the mail receiving execution mode according to his / her desire into a specific component of the transmitted e-mail and transmits the same. The terminal device receives and executes an e-mail in a form desired by the transmitting user according to the control information.

The present invention also provides an electronic mail distribution service function that divides an electronic mail transmitted from a transmitting terminal device into a plurality of components and selectively downloads them to a receiving terminal device. In the case where the present invention is realized by a mail server provided with, when the mail reception execution control means receives and executes an e-mail addressed to itself from the mail server, it first receives a specific component of the e-mail, The control information is extracted from the specific component received. When the control information is extracted by the extraction means, the control unit receives unacquired components including the attached file of the e-mail from the mail server, and executes the execution form of each received component by the extracted control. It is also characterized by variable control based on information.

In this manner, according to the control information, not only the control of the execution form of the received mail but also the selection and order of the elements when downloading the respective elements of the e-mail from the mail server, that is, each element It is also possible to control the receiving form of the element.

Further, according to the present invention, the mail transmission control means inserts control information designating the reception execution order of each component of the electronic mail into a specific component of the electronic mail and transmits the same. In the means,
It is also characterized in that, based on control information extracted from specific components of the received e-mail, the reception execution order of each component of the received e-mail is controlled.

Specifically, when the e-mail transmission control means creates and transmits an e-mail with an attached file containing image data for notifying of reception, a specific component of the e-mail is added to the e-mail. The control information for designating the execution order of the attached file to be the first among the elements constituting the mail is inserted and transmitted, while the mail reception execution control means extracts from the specific component of the received e-mail. Based on the obtained control information, the received attached file is executed before other constituent elements.

When the e-mail transmission control means creates and transmits an e-mail with an attached file containing audio data for notifying reception, the e-mail is configured as a specific component of the e-mail. In each element, the control information designating the execution order of the attached file as the first place is inserted and transmitted, and the mail reception execution control means adds the control information extracted from the specific component of the received e-mail to the control information. On the basis of this, the received attachment is executed before other components.

By doing so, it becomes possible for the transmitting user to arbitrarily specify the order of receiving and executing a plurality of elements constituting the electronic mail. For example, it is possible to display the attached file in which the face image data of the transmitting user or the audio data of the incoming melody is inserted before the header information and the text, thereby expanding the use of the attached file.

Further, according to the present invention, when an e-mail attached with a plurality of attached files is created and transmitted by the mail transmission control means, the reception execution form of the plurality of attached files is added to a specific component of the e-mail. The specified control information is inserted and transmitted. On the other hand, the mail reception execution control means selectively receives the plurality of received attached files based on the control information extracted from a specific component of the received e-mail. It is also characterized by being executed sequentially or simultaneously.

In this way, for example, when image data and audio data are sent as separate attached files, the image data and the attached file can be simultaneously displayed and reproduced on the receiving terminal device. It becomes possible. In addition, it is also possible to sequentially reproduce the audio data or the image data first, and then display the document data representing the explanation.

As the control information notifying means, an additional item which can be optionally used by the user is provided in the header information, control information is inserted into this additional item, and a notification is made. It is conceivable that the control information is notified by inserting the control information into the. In the former case, the control information can be reliably notified without being mixed with other existing information,
In the latter case, there is an advantage that control information can be notified using an existing item without adding a new item.

Further, according to the present invention, in the mail reception execution control means, prior to obtaining the attached file, whether at least one of the source, date and time, name, format and attribute of the attached file satisfies a predetermined condition. It is also characterized in that it has a function of determining whether or not the file is attached and acquiring the attached file when satisfied.

By doing so, it is possible to acquire only the attached file suitable for reception and execution, thereby securing the security of the terminal device on the receiving side and not wastefully using the storage memory of the terminal device. In this manner, the effective use of the memory capacity can be achieved. This effect is particularly important for a portable terminal having a relatively small memory capacity.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIG. 1 is a schematic configuration diagram of a mobile communication network system which is a first embodiment of a communication network system according to the present invention.

In the service area covered by the system, a plurality of base stations BS1 to BSn are distributed and arranged, and these base stations BS1 to BSn each form a radio zone called a cell. Also, the base stations BS1 to BS
n is connected to the mobile communication network NW via a wired line. This mobile communication network NW is connected to a computer network such as a wired communication network or the Internet (not shown).

The portable terminals MS1, MS2,...
The base stations BS1 to BSn are further connected to the mobile communication network NW. By being exchanged and controlled by the mobile communication network NW, the mobile communication network NW is connected to another portable terminal in the system or another wired terminal connected to the wired communication network, and for example, a call can be made between these terminals. Becomes

The mobile communication network NW has an Internet mail distribution service function for providing an electronic mail distribution service in addition to the above exchange control function. This Internet mail distribution service function is provided by the mobile terminal MS.
.. Transfer and distribute electronic mails (e-mails) as transmission sources or destinations via the Internet according to the TCP / IP protocol, and include a mail server SV for distribution of the electronic mails. .

The mail server SV receives the e-mail sent from the transmitting terminal, temporarily stores the e-mail, and stores the e-mail in IMAP4 (Internet Message Access Protocol-V).
ersion4) Delivery to the destination mobile terminal according to the protocol specified in 4). The IMAP 4 divides the header information, the body, and the attached file, which are the components of the e-mail, according to the download format requested by the destination mobile terminal,
These components are downloaded in any combination.

As the combination pattern of the download, for example, the header information, the main body, and the attached file are downloaded in response to separate download requests after the mail arrival notification, and the header information is first downloaded in response to the download request after the mail arrival notification. Then, the body and attached file are downloaded together in response to another download request, and the header information and body text are downloaded in response to the download request after the mail arrival notification, and then attached in response to another download request Some download files. In addition,
It is also possible to divide a plurality of elements constituting the header information and selectively download them in response to a download request.

By the way, the portable terminals MS1, MS2,
... is constituted as follows. FIG. 2 is a block diagram showing the functional configuration. Radio frequency signals transmitted from the base stations BS1 to BSn are received by the antenna 1 and then input to the receiving circuit (RX) 3 via the antenna duplexer 2 (DUP). In the receiving circuit 3, the radio frequency signal is mixed with the receiving local oscillation signal output from the frequency synthesizer (SYN) 4 and frequency-converted into an intermediate frequency signal. Note that the frequency of the reception local oscillation signal generated from the frequency synthesizer 4 is specified by a control signal SYC from the control unit 12.

The received intermediate frequency signal is subjected to despreading processing by a spreading code (PN code) assigned to a receiving channel in a CDMA signal processing unit 6, and then subjected to quadrature demodulation corresponding to, for example, a QPSK modulation method. Thus, the data is converted into demodulated data in a predetermined format according to the data rate. The converted demodulated data is input to the compression / decompression processing unit 7.

The compression / expansion processing unit 7 performs an expansion process on the demodulated data output from the CDMA signal processing unit 6 according to the reception data rate notified from the control unit 12, and then uses Viterbi decoding or the like. The decoding processing and the error correction decoding processing are performed to reproduce the baseband received voice data or received packet data. The received voice data is output to the PCM code processing unit 8 and the received packet data is output to the control unit 12.

The PCM code processing section 8 includes a compression / decompression processing section 7
PCM decodes the received voice digital data output from, and outputs an analog reception signal. This analog reception signal is amplified by the reception amplifier 9 and then output from the speaker 10 as loudspeaker.

The control unit 12 depackets the received packet data output from the compression / decompression processing unit 7 and stores it in the storage unit 13. 15 is displayed. When a personal computer such as a personal digital assistant (PDA) or a notebook personal computer is connected to the mobile terminals MS1, MS2,... The data may be output to the personal computer via the personal computer.

On the other hand, the input voice signal of the speaker input to the microphone 11 during voice communication is transmitted to the transmission amplifier 1.
After being amplified to an appropriate level by the PCM 8, the PCM code processing section 8 performs PCM coding processing, and inputs it to the compression / decompression processing section 7 as transmission audio data. Control unit 1
The packet data such as the e-mail created in step 2 is input from the control unit 12 to the compression / decompression processing unit 7.

At the time of voice communication, the compression / decompression processing unit 7
The energy amount of the input voice is detected from the transmission voice data output from the CM code processing unit 8, and the data rate is determined based on the detection result. Then, the transmission audio data is compressed into a signal having a format corresponding to the data rate, further subjected to an error correction coding process, and then subjected to CDMA.
Output to the signal processing unit 6. On the other hand, at the time of packet data transmission, the transmission packet data output from the control unit 12 is subjected to error correction coding processing and output to the CDMA signal processing unit 6.

The CDMA signal processing unit 6 subjects the carrier signal to, for example, QPSK modulation using the transmission data compressed by the compression / decompression processing unit 7, and applies a PN code assigned to each transmission channel to the modulated carrier signal. To perform a spread spectrum process. Then, the spread-coded transmission signal is output to the transmission circuit (TX) 5.

The transmission circuit 5 synthesizes the spread-coded transmission signal with a transmission local oscillation signal generated from the frequency synthesizer 4 and converts the frequency into a radio frequency signal. Then, based on the transmission data rate notified by the control unit 12, the transmission circuit 5 amplifies only the effective portion of the radio frequency signal at a high frequency and outputs it as a transmission radio frequency signal. The transmission radio frequency signal output from the transmission circuit 5 is supplied to the antenna 1 via the antenna duplexer 2,
The signal is transmitted from the antenna 1 to the connected base station.

The input unit 14 is provided with a key group such as a dial key, a transmission key, a power key, an end key, a volume adjustment key, and a mode designation key. Also, the display unit 15
An LCD display and an LED lamp are provided. LCD
The display displays the telephone number of the terminal of the communication partner, the operation state of the terminal itself, transmitted and received mails, and the like. Also LE
The D lamp is used to indicate the discharge state of the battery 16. Reference numeral 17 denotes a power supply circuit which generates a predetermined operation power supply voltage Vcc based on the output of the battery 16 and supplies it to each circuit section.

The control section 12 has a microprocessor as a main control section. The control functions include a communication link control function for establishing a communication link with a base station in response to an outgoing / incoming call, and a control function for recording / reproducing the voice of the other party using the storage unit 13 during voice communication. In addition to the normal control functions such as the mail transmission control function 12a and the mail type determination function 12a as new functions according to the present invention.
b and a mail reception execution control function 12c.

The mail transmission control function 12a sets an additional item in the header of the e-mail when the sending user performs a push mail designation operation when creating and transmitting the e-mail. A keyword indicating a push mail, that is, “PushMail: ON” is inserted and transmitted. Here, the push mail is a mail in which the attached file is executed before the text without any user operation on the terminal device on the receiving side.

The mail type determining function 12b downloads the header of the electronic mail from the mail server SV when the notification of the arrival of the electronic mail addressed to itself arrives from the mail server SV. Then, a keyword is extracted from the additional items of the header, and it is determined from the keyword whether the electronic mail is a normal mail or a push mail.

The mail reception execution control function 12c has a normal mail reception execution control function and a push mail reception execution control function. The normal mail reception control function, when the normal mail is determined by the mail type determining function 12b, converts each component of the electronic mail, that is, the header information, the body, and the attached file according to the manual operation of the receiving user. This is a function of sequentially downloading and displaying from the mail server SV in a normal procedure.

The push mail reception execution control function automatically transmits a request for downloading a text and an attached file to the mail server SV when the mail type determination function 12b determines that the mail is a push mail, and responds to this request. This is a function of displaying the text and the attached file downloaded from the mail server SV on the display unit 15 in the order of the attached file, the header, and the text.

Next, an electronic mail transfer operation in the system configured as described above will be described. FIG. 3 is a flowchart showing a mail transmission control procedure and its contents in the transmitting portable terminal, and FIG. 4 is a flowchart showing a mail receiving execution control procedure and its contents in the receiving portable terminal.

For example, assume that a push mail is transmitted from the portable terminal MS1 to the portable terminal MS2. When the sending user performs an operation of creating an e-mail in the mobile terminal MS1 on the transmitting side, the control unit 12 displays a template for creating an e-mail. Using this template, the transmitting user inputs a destination, a subject, and a text, respectively, and then performs an operation for attaching, for example, his / her own face image data as an attached file to the text. Mobile terminal M
The control unit 12 in S1 fetches the destination, the subject, and the body in step 3a to create a header and a body of the e-mail, and performs a process for attaching the attached file to the body in step 3b.

Next, the control section 12 of the portable terminal MS1 determines the type of the transmitted mail in step 3c. In this state, when the sending user performs a push mail selection / designation operation, the control unit 12 proceeds to step 3d and determines whether or not the attached file has been attached. In the above, an additional item is set in the header of the e-mail using "X -...", and a keyword "PushMail: ON" for display of push mail as control information is set in the additional item as shown in PM1 of FIG. insert. When the sending user performs a sending operation, the created email is sent as a push mail in step 3f.

If the sending user performs a normal mail selection designation operation or a mail transmission operation without performing the push mail selection operation, the control unit 12 proceeds from step 3c to step 3f. Here, the e-mail created above is transmitted as a normal e-mail.

The push mail or the normal mail transmitted from the portable terminal MS1 is sent to the mobile communication network NW via the base station BS1 as shown in FIG. 5, and then stored in the mail server SV. When the push mail or the normal mail is received, the mail server SV creates mail structure information based on the received mail. The mail structure information includes management information of the attached file, and the management information includes an attached file name, an extension, a file size, and the like.

On the other hand, the mobile terminal MS2 on the receiving side is controlled by the control unit 12 during the standby period as shown in FIG.
At a, the arrival of an incoming notification from the mail server SV is monitored. In this state, when an e-mail arrival notification is transmitted from the message server SV to the portable terminal MS2 as shown in FIG. 5, the control unit 12 of the portable terminal MS2 proceeds to step 4b.
First, the mail server SV is requested to download the header, and in response to the download request, the mail server SV
Receives the header that it sends.

The control unit 12 of the portable terminal MS2
In step 4c, it is determined whether or not the push mail display keyword "PushMail: ON" is inserted as an additional item in the received header. If the result of this determination is that the push mail display keyword "PushMail: ON" has not been inserted, it is determined that the target e-mail is a normal e-mail, and the process proceeds to step 4m. Display in addition to the received mail list.
The reception and execution of the normal mail are performed according to a manual operation of the receiving user.

Now, it is assumed that as a result of the above determination, the keyword "PushMail: ON" for displaying the push mail is inserted in the header. Then, the control unit 12 determines that the target e-mail is a push mail, shifts to step 4d, and transmits a request to download mail structure information to the mail server SV. When the mail structure information is downloaded from the mail server SV, the attached file management information is extracted from the mail structure information in step 4e. Then, it is determined whether or not the attached file is an executable file based on the Content Type included in the management information of the extracted attached file.

For example, it is determined in step 4f whether or not the attached file is an executable file based on the extension of the attached file.
It is determined whether or not the size of the attached file is a downloadable size.

As a result of the above determination, if the attached file is an executable file and has a downloadable size, the control unit 12 shifts to step 4h, where the control unit 12 sends the text and the attached file to the mail server SV. , And receives the text and attached file downloaded from the mail server SV in response to the download request. Then, in step 4i, the attached file is executed first, and then the header and the body are executed.

Therefore, if the face image data of the sending user is inserted in the attached file as described above, the face image data is displayed on the display unit 15 first. Therefore, the receiving user can immediately recognize the transmitting user based on the displayed face image data of the transmitting user.

During the display of the attached file, if the receiving user performs a confirmation operation or if a predetermined time elapses without performing the confirmation operation, the control unit 12 terminates the display operation of the attached file, and then To display header information and text.

In step 4h, a request is made to download only the attached file to acquire the attached file, and this is executed in step 4i. Thereafter, if necessary, a request for downloading the text is acquired and executed. Is also possible.

On the other hand, if it is determined in the above steps 4f and 4g that the attached file is in an unexecutable format, or if the file size is determined to be too large to download, the control is executed. The part 12 shifts to step 4j to display an error here. In this error display, for example, a message indicating that the attached file cannot be downloaded and the reason therefor are displayed. Then, during this error display, if the receiving user performs a confirmation operation, or if a predetermined time elapses without performing the confirmation operation, the control unit 12 ends the error display operation. Then, the process proceeds to step 4k, where the received header is displayed in addition to the received mail list. The reception and execution of the normal mail are performed according to a manual operation of the receiving user.

Note that step 4f and step 4
In the determination of g, if the attached file is determined to be a file in an infeasible format or if the file size is determined to be undownloadable, only the body is downloaded without downloading the attached file You may do so.

As described above, in the first embodiment, when the transmitting portable terminal MS1 transmits a push mail with its own face image data attached as attached data, the header for displaying the push mail is added to the header. "Push
Mail: ON "is inserted as an additional item and transmitted. On the other hand, in the portable terminal MS2 on the receiving side, when an incoming call notification arrives, first, only the header is obtained from the mail server SV, and the keyword “PushMail: ON” for displaying the push mail is inserted into the header. Is determined. If it is inserted, the body and the attached file are sequentially acquired from the mail server SV, and the attached file is displayed first.

Therefore, if the transmitting terminal user transmits the push mail, the transmitting terminal can display the attached file first on the receiving portable terminal MS2, and the receiving terminal user can use the face image data transmitted by the attached file. The sender can be immediately recognized. That is, the use of the attached file can be further expanded.

Further, the download of the body of the push mail and the attached file from the mail server SV and the execution processing thereof are automatically performed. Therefore, the receiving terminal user does not need to perform any operation for acquiring and executing the push mail.

Further, in the first embodiment, when acquiring an attached file from the mail server SV, it is determined whether or not the attached file is an executable file based on the extension of the attached file. At the same time, it is determined whether the size of the attached file is a downloadable size. And if it is determined that the attached file is a file of an unexecutable format, or if it is determined that the file size is large and cannot be downloaded,
Attachments are not downloaded.

Therefore, the portable terminal MS2 on the receiving side can download only the attached file suitable for reception and execution, thereby ensuring the security of the portable terminal MS2 on the receiving side and the storage unit of the portable terminal MS2. 13 can be used effectively so that the memory capacity can be effectively used. This effect is particularly important for a portable terminal having a relatively small memory capacity.

In the above description, it is determined whether or not the attached file is an executable file and whether or not the size of the attached file is a downloadable size. It is also possible to selectively use these conditions to determine whether or not to download a file, using the sender name of the file, its address, date and time, attached file name, and the like.

(Second Embodiment) In a second embodiment of the present invention, a keyword for displaying a push mail is inserted at the head position of the "Subject" item already provided in the header. And send it. FIG. 7 shows an example of the inserted state. In the position shown by PM2 in the figure, a push mail display keyword "PushMai" is displayed.
l ”is inserted.

FIG. 8 is a flowchart showing a mail transmission control procedure of the transmitting portable terminal according to the second embodiment and its contents, and FIG. 9 shows a mail receiving execution control procedure and its contents in the receiving portable terminal. It is a flowchart. Note that, in this figure, the same parts as those in FIGS. 3 and 4 are denoted by the same reference numerals, and detailed description is omitted.

The control unit 12 of the portable terminal MS1 on the transmitting side
When detecting the push mail selection designation operation by the sending user in step 3c, it is confirmed in step 3d that the attached file is already attached, and then step 3e is performed.
Then, a push mail display keyword "PushMail" is inserted at the head position of "Subject" provided in the header of the transmitted e-mail. Then, in accordance with the transmission operation of the transmission user, the electronic mail is transmitted as a push mail in step 3f.

On the other hand, the control unit 1 of the portable terminal MS2 on the receiving side
2 receives the header from the mail server SV in step 4b, in step 9a the
bject) ”, the keyword“ PushMail ”for push mail display is extracted from the top position. When the push mail display keyword "PushMail" is extracted, the process proceeds to step 4d, where a request to download mail structure information is transmitted to the mail server SV. And
When the mail structure information is downloaded from the mail server SV, the attached file management information is extracted from the mail structure information in step 4e. Then, based on the extension of the attached file and the size of the attached file included in the management information of the extracted attached file, step 4f is performed.
In step 4g, it is determined whether the attached file is an executable file and whether the file size is a downloadable size. If the file is a downloadable attachment file, the body and the attachment file are acquired from the mail server SV in step 4h. Then, in step 4i, the acquired attached file is executed first.

Therefore, according to the second embodiment as well, the attached file can be executed first on the portable terminal MS2 on the receiving side at the request of the transmitting user, thereby further expanding the use of the attached file. be able to.

Further, according to the second embodiment, a push mail display keyword is inserted into the head position of the “Subject” item already provided in the header and transmitted. Therefore, it is not necessary to provide a new item for transmitting a push mail display keyword, so that a general-purpose header can be used as it is, and an increase in the header size can be prevented.

(Third Embodiment) In a third embodiment of the present invention, a target electronic mail is determined to be a push mail by a keyword of a header obtained from a mail server in a terminal device on the receiving side. In this case, before obtaining the body of the push mail and the attached file, it is determined whether the attached file is an executable file based on the extension of the attached file,
It is determined whether the size of the attached file is a downloadable size. And if both conditions are met, the body and the attached file are acquired and displayed at the same time,
If at least one of the conditions is not satisfied, only the text is acquired.

FIG. 10 is a flowchart showing a mail reception execution control procedure of the portable terminal on the receiving side according to the third embodiment and its contents.

The portable terminal MS2 on the receiving side is controlled by the control unit 12 in the mail server SV in step 10a during the standby period.
Watch for incoming call notifications from. In this state, when an e-mail arrival notification is transmitted from the message server SV, the control unit 12 of the portable terminal MS2 proceeds to step 10b.
First, the mail server SV is requested to download the header, and in response to the download request, the mail server SV
Receives the header downloaded from.

Then, the control unit 12 of the portable terminal MS2
"Subject (Subjec
In step 10c, it is determined whether or not the push mail display keyword "PushMail" is inserted at the head position of the item "t)". If the result of this determination is that the push mail display keyword “PushMail” has not been inserted, it is determined that the target e-mail is a normal e-mail, and the process proceeds to step 10j. Display in addition to the list. The reception and execution of the normal mail are performed according to a manual operation of the receiving user.

Now, it is assumed that as a result of the above determination, a push mail display keyword "PushMail" has been inserted into the header. Then, the control unit 12 determines that the target e-mail is a push mail, and
To acquire the mail structure information from the mail server SV, and extract the attached file management information from the structure information. Then, it is determined whether or not the attached file is an executable file based on the extension of the attached file included in the attached file management information.
At 0e, it is determined whether or not the size of the attached file is a downloadable size.

As a result of the determination, if the attached file is an executable file and has a downloadable size, the control unit 12 proceeds to step 10f and downloads the body and the attached file to the mail server SV. Is received, and the body and the attached file downloaded from the mail server SV in response to the download request are received. Then, in step 10g, the attached file is executed first, and then the header and the body are executed.

Therefore, if the face image data of the sending user is inserted in the attached file, the face image data is displayed on the display unit 15 first. Also, if the music or melody unique to the transmitting user or the voice data of the transmitting user is inserted in the attached file, the music, the melody, or the voice data of the transmitting user is reproduced and output before the header and the text are displayed. You. Therefore, the receiving user can immediately and clearly recognize the transmitting user by the displayed face image data of the transmitting user, music or melody unique to the transmitting user, or voice data of the transmitting user.

During the display of the attached file, if the receiving user performs a confirmation operation or if a predetermined time elapses without performing the confirmation operation, the control unit 12 terminates the display operation of the attached file and continues. To display header information and text.
