Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a receiving apparatus and method, a transmitting apparatus and method, a communication system, and a program storage medium, and more particularly to a receiving apparatus and method for transmitting or receiving electronic mail, a transmitting apparatus and method, and communication. The present invention relates to a system and a program storage medium.

[0002]

2. Description of the Related Art A system for transmitting and receiving text-based data via a network or the like, that is, an electronic mail system is widely used.

A receiving device that has received an e-mail displays the received e-mail in text.

[0004] There are times when a sender of an electronic mail wants a reader of the electronic mail to perform some action.

[0005] In Japanese Patent Application Laid-Open Nos. 2000-47955 and 11-65964, data used for executing an application program is transmitted by an e-mail in order to allow a recipient of the e-mail to perform some processing or action. Discloses an invention for transmitting and receiving data.

[0006]

However, the desired action of the sender of the electronic mail is not always executed.

[0007] For example, a person who has received an e-mail reads the e-mail, understands the contents of the e-mail correctly,
If the other party does not perform the action, the sender's desired action is not performed.

Similarly, when data is attached to an electronic mail, the action is not executed unless an application program corresponding to the attached data is executed on the receiving side.

For example, when the confirmation of the attendance of the drinking party is transmitted by e-mail, the sender of the e-mail expects the reader of the e-mail to read the e-mail and reply to the attendance.

However, in the prior art, in order for the sender of the e-mail to receive the reply of the attendance, the reader must correctly understand the contents of the received e-mail, check the schedule, and send the reply to the e-mail. The attendance must be correctly filled out and returned to the sender.

There is no guarantee that the sender of the e-mail will receive the attendance reply.

In such a case, a possible solution is to attach an application program that returns a reply as described above and have the reader execute the program. In this case, the reader must start the application program.

When playing a game such as Othello via electronic mail, an Othello board is described by + or-symbols, and a frame is described by black or white circles.
The game can be advanced by sending them as text.

However, when a new hand is inserted,
Since the user shifts the arrangement of the symbols, it is necessary to correct the shift.

[0015] The content of the game screen is, for example, PowerPoi
It is also conceivable that the generated file is described in nt (trademark) (application program of Microsoft Corporation) or the like, and the generated file is attached to an electronic mail and transmitted. In this case, the e-mail reader must start the corresponding application program one by one,
If you do not have the corresponding application program, you cannot see the game screen.

In addition, in the case of a game such as Othello, the user must execute a process of determining whether or not a newly input hand has been hit in a correct place according to rules, and turning over a frame with the new hand. The problem is that mistakes often occur.

The present invention has been made in view of such circumstances, and has as its object to promptly and surely cause a reader of an e-mail to execute an action desired by an e-mail sender.

Called.

Next, transmission and reception of electronic mail via the Internet 4 will be described.

The mechanism for sending or receiving an e-mail via the Internet 4 is very similar to the mechanism for sending a mail such as a postcard. For mail,
1. Write a letter, 2. 2. Post to the post. 3. Transfer between post offices; One letter arrives at the recipient through the four steps of delivering to the mailbox.

In the case of e-mail via the Internet 4, Write an e-mail on a mail transmission / reception program; Press the send button of the mail sending and receiving program,
3. 3. Transfer between mail servers The e-mail reaches the partner through four steps of pressing the reception button of the mail transmission / reception program.

The mail sending / receiving program is a program for writing an electronic mail and sending it to the other party, or receiving the electronic mail sent by the other party. The mail sending and receiving program is
It is also called a mailer and has a function corresponding to a post and a mailbox.

Most mail sending / receiving programs have an editor function for displaying an e-mail on a screen or writing an e-mail. The user operates the mail sending / receiving program to send or receive an e-mail.

As a typical mail sending / receiving program,
Microsoft's OutlookExpress (TM), Qualcomm's Eudora Pro (TM), and free software Becky! InternetMail or Al-Mail32.

The mail server plays the role of a post office, so to speak. The mail server receives the e-mail transmitted by the e-mail transmission / reception program, and transmits the e-mail to the e-mail transmission / reception program. A typical mail server program is sendmail (trademark) of Sendmail Corporation of the United States.

The mail server has three main roles. First, an e-mail received from a mail transmission / reception program is appropriately transmitted to another mail server.
Second, e-mails received from other mail servers are organized and managed by destination (user). Third, the electronic mail being managed is transmitted to the mail transmission / reception program in response to a request from the mail transmission / reception program.

The procedure for the mail sending / receiving program to send an electronic mail to the mail server is different from the procedure for the mail server to send the email to the mail sending / receiving program, and the communication procedure is different.

The communication procedure is called a protocol. The process of sending e-mail to the mail server by the mail sending / receiving program and the process of sending e-mail to the mail server by the mail server include SMTP (Simple M
ail Transfer Protocol) is widely used.

The process of receiving an e-mail from the mail server by the mail transmission / reception program includes POP3 (Post Off
ice Protocol Version3) is widely used.

The port corresponding to SMTP and the port corresponding to POP3 in the mail server are different from each other. When sending and receiving e-mails,
It communicates with the mail server via the port corresponding to SMTP, and when receiving e-mail, the mail server and POP3
Communicate via the port corresponding to.

In the case of mail, a letter sent from a foreign country is stamped for each country passed. Similarly, email
Postmarked.

When an e-mail is transmitted, postmark information is added to the head of the e-mail body one after another every time the e-mail is passed through the mail server. Since attached to the head, this postmark information is called a header.

The header is roughly composed of three blocks. The block attached to the mail transmission / reception program is arranged in the lowermost part (the part close to the text), and the blocks attached to the mail server are arranged in the two upper parts.

The header stores new information at the top.

The header information attached to the mail transmission / reception program is composed of the same information as the address of the letter. From stores the mail address of the sender, To stores the mail address of the destination, and Subject stores the title.

[0075] Of the blocks attached by the mail server, Re
In ceived, a time stamp is stored. form stores the name of the mail server that passed.

The mail server sends the e-mail
Attached to this Received block. Therefore, by checking the description of Received blocks in order from bottom to top,
You can know the mail server through which the e-mail has passed.

Next, the setting of the mail transmission / reception program will be described. The information that must be correctly set for sending an e-mail is the e-mail address corresponding to the mail transmission / reception program and the host name of the mail server corresponding to SMTP.

The e-mail address corresponding to the mail transmission / reception program is a source address corresponding to the sender name. When the e-mail address corresponding to the e-mail transmission / reception program is not set, the recipient of the e-mail cannot know the sender, and when the destination is unknown, the e-mail cannot be returned.

The mail sending / receiving program inserts an electronic mail address corresponding to the mail sending / receiving program into the From line in the header. The e-mail address corresponding to the mail transmission / reception program is also used as a destination when the other party writes a reply. Depending on the mail transmission / reception program, the destination of the reply can be changed by setting the item of the reply address.

The host name of the mail server to which the mail sending / receiving program sends the electronic mail is set as the host name of the mail server corresponding to the SMTP. When sending an e-mail, the mail transmission / reception program sends the e-mail to the mail server based on the host name of the mail server corresponding to the SMTP. The host name is, for example, mailserver.so-
It is described as net.ne.jp.

The e-mail address and the host name are described based on the domain name. In the domain name, the country name, the type of organization, and the company name are represented by connecting “.”. In a domain name, a larger section is located later.

The e-mail address is the user's name,
It is indicated by attaching "@" as a delimiter and further connecting a domain name.

The host name is expressed by adding "." As a delimiter to the server name, and further connecting the domain name.

The electronic mail address or host name is a unique mail address or host name by being described as described above.

The e-mail address and host name include
Japanese cannot be used. Also, only lowercase letters are used in domain names. Even if you set an uppercase alphabet, it is automatically converted to lowercase.

Next, transmission of an electronic mail to the mail server by the mail sending / receiving program will be described. The e-mail sending and receiving program, when sending e-mail,
You must get the IP address corresponding to the host name. The IP address is described by a combination of a numeral and “.”, For example, 192.168.0.1.

The DNS is a system for converting a host name into an IP address. Internet 4 has several DNs
S server is installed. When a host name is sent to one of the DNS servers, the DNS server returns an IP address corresponding to the host name.

For example, the DNS server 14-1 in FIG. 2 records an IP address aaaa in association with the host name A.

The mail sending / receiving program sends the I / O of the mail server from the DNS server immediately before accessing the mail server.
Ask your P address.

Next, a procedure for transmitting an electronic mail from the mail transmitting / receiving program to the mail server will be described.
The mail sending / receiving program and the mail server send an e-mail from the mail sending / receiving program to the mail server according to the SMTP procedure.

The SMTP procedure is based on TCP (Transmission Control).
l Protocol) setup, calling the mail server, preparing for transmission, notification of destination, transmission of text, confirmation of termination,
And termination of TCP. The processing of calling the mail server, preparing for transmission, notifying the destination, transmitting the text, and confirming the end are all composed of a request from the mail transmission / reception program and a reply from the mail server.

In the SMTP processing, the mail sending / receiving program and the mail server communicate with each other by using a command statement and a reply code. For example, the command statement “RCPT from:
y@so-net.ne.jp ”, the RCPT is a command to notify the destination of the e-mail, and the destination of the e-mail is y @ so
-net.ne.jp.

In the reply code, for example, “Yes”
250. To explain some of the reply codes, 251
Indicates "no such user exists" and 450
Indicates "Mailbox is in use" and 451
Indicates "Error occurred and terminated abnormally."
Indicates “insufficient resources required for processing”, 501 indicates “command syntax is incorrect”, 502 indicates “command cannot be used”, 550
Indicates "Mailbox does not exist".

E-mail has a broadcast function. The lifetime broadcast function is a function to send an e-mail with the same text to any number of people.

For example, if a plurality of mail addresses are described in the To line of the header, the mail sending / receiving program
The process of transmitting the PT command is repeated for each address described in the mail address.

The Cc (carbon copy) line or B
Broadcasting can also be performed using a special header such as a cc (blind carbon copy) line.

When an e-mail is transmitted using the Cc line or the Bcc line, the recipient of the e-mail receives a copy of the e-mail because his or her address is not described in the To line of the header. You can know that.

When an e-mail is transmitted using the line Cc, the mail address of the other party is stored in the header. When an e-mail is transmitted using the Bcc line, the mail transmission / reception program deletes the Bcc line from the header after transmitting the RCPT command, and transmits the text. The transmission of an e-mail using the Bcc line is effective when it is not desired to inform the other party of the broadcast destination.

Next, a process in which the mail server searches for a mail server near the destination and transfers the mail server will be described. The process of transferring the e-mail from the mail server to the mail server is performed according to the SMTP procedure.

In the process of transferring an e-mail from the mail server to the mail server, the mail server transmitting the e-mail cuts out the domain name from the destination of the e-mail and sends the cut-out domain name to the DNS server.

Since the DNS server records the relationship between the domain name and the host name of the mail server as an MX record, the host name of the mail server corresponding to the domain name is
Send the domain name to the mail server that sent it.

For example, the DNS server 14-2 in FIG. 2 records the host name B in association with the domain name BBB.

The mail server having received the host name sends the host name to the DNS server.

Since the DNS server records the relationship between the host name and the IP address as an A record, the DNS server transmits the IP address corresponding to the host name to the mail server that transmitted the host name.

For example, the DNS server 14-2 in FIG. 2 records the IP address bbbb in association with the host name B.

The mail server that has transmitted the IP address transmits the electronic mail to the mail server corresponding to the domain name of the destination of the electronic mail based on the above-described SMTP procedure.

The mail server can broadcast an e-mail using a mailing list. When broadcasting an e-mail using a mailing list, an alias function is used.

The mail server using the alias function records a plurality of addresses in advance in groups corresponding to predetermined mail addresses (representative addresses). When receiving the e-mail addressed to the representative address, the mail server retransmits a copy of the e-mail to all of the plurality of addresses recorded corresponding to the representative address. The mail server sends e-mails one after another to the registered mail addresses without rewriting the header.

The mail server corresponding to the domain name stores the received electronic mail in a mailbox called spool. The mail server manages the e-mail for each user, and distributes the e-mail when the reception button of the mail transmission / reception program of the user corresponding to the destination is pressed.

The reason that the mail server does not transmit the e-mail to the mail transmission / reception program based on the SMTP may be that the device executing the mail transmission / reception program is not operating or is not connected to the Internet 4. That's why.

The mail server transmits an e-mail to the mail transmission / reception program based on POP3. POP3 procedures include TCP setup, mail server call, user authentication, mailbox content confirmation, number of incoming calls, text reception, deletion request, termination confirmation, and TCP
Of the end of the process.

The number of incoming e-mails 204 addressed to the user is transmitted to the mail server 13-2, and the number of incoming e-mails 204 is received.

In step S57, the mail sending / receiving program 304 sends the electronic mail 20 addressed to the user of the PDA 1 to the mail server 13-2 via the USB interface 85.
4 is transmitted, and the transmitted electronic mail 204 is received. In step S58, the mail transmission / reception program 304 causes the USB interface 85 to request the mail server 13-2 to delete the electronic mail 204 addressed to the user of the PDA 1. The mail server 13-2 deletes the electronic mail 204 addressed to the user of the PDA 1.

In step S59, the mail transmission / reception program 304 causes the USB interface 85 to confirm the end of processing with the mail server 13-2.

In step S60, the mail transmission / reception program 304 causes the USB interface 85 to disconnect from the mail server 13-2.

In step S61, the mail transmission / reception program 304 causes the script cache system 206 to execute processing for storing the received e-mail 204, and the processing ends.

[0211] As described above, the PDA 1 is
-2, the electronic mail 204 addressed to the user of the PDA 1 can be received and stored.

Next, a description will be given, with reference to a flowchart of FIG. 30, of a process of storing the electronic mail 204, which is executed by the script cache system 206 and corresponds to the process of step S61 in FIG.

[0213] In step S71, the script cache system 206 extracts the hash value 205 inserted in the script program 202 of the received e-mail 204. In step S72, the script cache system 206 searches the script management table 212 with the extracted hash value 205.
The script cache system 206 has a hash value of 2
Since the script management table 212 is used, the script management table 212 can be searched at high speed.

[0214] In step S73, the script cache system 206 determines whether or not the extracted hash value 205 is already stored in the script management table 212, and the extracted hash value 205 is not stored in the script management table 212. If it is determined, the process proceeds to step S74, where the script program 202 attached to the electronic mail 204 is extracted, and the extracted script program 202 is stored in the file 211.

At step S75, the script cache system 206 sets the script management table 21
2 is generated, and the extracted hash value 205 and the file name of the file 211 are stored in the generated record. The script cache system 206 sets the reference count of the generated record to 0, and proceeds to step S
Proceed to 76.

If it is determined in step S73 that the extracted hash value 205 has already been stored in the script management table 212, the process of generating a record in the script management table 212 is not necessary, so steps S74 and S75 Skipped, the procedure goes to step S76.

At step S76, the script cache system 206 stores the script program 202 attached to the electronic mail 204 in the file name 208.
To generate the e-mail 207. In step S77, the script cache system 206
Saves the generated e-mail 207 in the storage 65.

At step S78, the script cache system 206 sets the script management table 21
The reference count of the corresponding record of No. 2 is increased by one (increment), and the process ends.

As described above, the script cache system 206 generates the electronic mail 207 by replacing the script program 202 of the received electronic mail 204 with the file name 208, and saves the generated electronic mail 207 together with the script program 202. Can be. When the same script program 202 as the script program 202 of the electronic mail 204 is already stored, the script cache system 206 does not store the new script program 202. Therefore, even if a plurality of e-mails 204 including the same script program 202 are received, the PDA 1 can store the e-mail 207 corresponding to the received e-mail 204 with a smaller storage area.

Next, with reference to the flowchart of FIG. 31, the execution of the script program 202 of the PDA 1 for executing the mail transmission / reception program 304 and the interpreter 306, which is executed when the mail transmission / reception program 304 displays the received e-mail, will be described. I will explain. In step S91, the mail transmission / reception program 304
Reads the e-mail 207.

In step S92, the mail transmission / reception program 304 determines whether or not the read electronic mail 207 includes the file name 208. If it is determined that the file name 208 is included, the process proceeds to step S92.
In step 93, the file name 208 inserted in the electronic mail 207 is extracted.

In step S94, the mail transmission / reception program 304 checks the file name corresponding to the read file name.
The file 211 storing the script program 202 is read.

In step S95, mail transmission / reception program 304 activates interpreter 306. The mail transmission / reception program 304 supplies the read script program 202 to the interpreter 306.

The interpreter 306 may be activated in advance together with the mail transmission / reception program 304.

In step S96, the interpreter 3
The execution module 322 of 06 executes the supplied script program 202.

In step S97, the interpreter 3
The output module 323 executes display or audio output processing according to the result of the execution of the script program 202. In step S98, the mail transmission / reception program 304 ends the interpreter 306, and the process ends.

In step S92, the file name 20
In a case where it is determined that No. 8 is not included, the processing corresponding to the script program 202 is not necessary, and thus the processing of steps S93 to S98 is skipped, and the processing ends.

As described above, the PDA 1 sends the e-mail 207
When the file name 208 is included in the file name, the interpreter 306 is activated, and the script program 202 corresponding to the file name 208 is executed.

The processing in step S92 is performed by the parsing module 32 of the interpreter 306 which has been started in advance.
1 may be executed.

Next, the Othello process, which is a more specific example of script execution, will be described with reference to the flowchart in FIG. In step S111, the mail sending / receiving program 304 sends the stored e-mail 207
Read.

[0231] In step S112, the mail transmission / reception program 304 starts the interpreter 306.
The interpreter 306 executes the script program 202 corresponding to the read electronic mail 207. In step S113, the output module 323 of the interpreter 306 causes the display unit 51 to display the Othello board and the frame.

In step S114, the execution module 322 determines whether or not a new hand has been input. If it is determined that a new hand has not been input, the execution module 322 proceeds to step S114 until a new hand has been input. And the process of the determination is repeated.

If it is determined in step S114 that a new hand has been input, the process proceeds to step S115,
The execution module 322 reads the new hand coordinates (indicating the position on the Othello board). In step S116, the execution module 322 determines whether the new hand satisfies the requirements specified in the Othello rule, and determines that the new hand satisfies the requirements specified in the Othello rule. If so, the flow advances to step S117 to place a frame at the position of the Othello board corresponding to the new hand.

In step S118, the execution module 322 updates the face of the frame, such as turning over a predetermined frame. In step S119, the output module 32
3 displays the Othello board and the frame on the display unit 51.

[0235] In step S120, the output module 323 causes the USB interface 85 to send an electronic mail 204 indicating a new hand to the other party. Step S
In 121, the mail transmission / reception program 304 terminates the interpreter 306, and the process ends.

If it is determined in step S116 that the new hand does not satisfy the requirements specified in the Othello rule, the process proceeds to step S122, where the output module 323 causes the display unit 51 to display an error, An error is notified to the user, and the procedure returns to step S114, and the process is repeated from the input of a new hand.

As described above, the PDA 1 transmits the e-mail 207
Is executed based on the script program 202 corresponding to.

Next, referring to the flowchart of FIG. 33, the script cache system 206 executes
A process of updating the script management table 212 corresponding to the deletion of the electronic mail 207 will be described.

[0239] In step S151, the script cache system 206 sends the e-mail 20 to be deleted.
7 is extracted.

In step S152, the script cache system 206 sets the extracted file name 208
Is used to search the script management table 212. In step S153, the script cache system 20
No. 6 decrements the reference count of the corresponding record in the script management table 212 by one.

[0241] In step S154, the script cache system 206
It is determined whether or not the reference count of the corresponding record of No. 12 is 0. If it is determined that the reference count is 0, the process proceeds to step S155, and the file 211 corresponding to the file name 208 is deleted.

At step S156, the script cache system 206 sets the script management table 2
12, the record corresponding to the file name 208 is deleted, and the process ends.

If it is determined in step S154 that the reference count is not 0, the file 211 and the script management table 2 corresponding to the file name 208 are set.
Since there is no need to delete 12 records, step S
155 and step S156 are skipped,
The process ends.

As described above, when the electronic mail 207 is deleted, the script cache system 206 updates the record of the script management table 212 and deletes the file 211 storing the unnecessary script program 202. Can be.

By doing so, the PDA 1 can use the memory space of the storage 65 more effectively.

As described above, when the user attempts to read the e-mail 207, the PDA 1 executes the action desired by the sender of the e-mail 204. When the user does not read the e-mail 207, the PDA 1
Since the script program 202 corresponding to No. 7 is not executed, the processing load of the script program 202 can be minimized.

The PDA 1 can execute various processes corresponding to the description of the script program 202 only by executing the interpreter 306. There is no need to store a large number of application programs corresponding to the type of data obtained.

Also, since the interpreter 306 executes the script program 202, the interpreter 306
Can be executed more securely than when the execution program attached to the e-mail is directly executed.
