When content is downloaded from the various content providing servers on the Internet 30 to the user terminal devices 10S and 10R, a predetermined communication protocol is used in each layer of the network. For example, as a communication protocol of the application layer when downloading a WEB page from the WEB server 40, HTTP (HyperText Transfer Protocol), W-HTTP (Wireless HyperText Transfer Protocol), WTP (Wireless Transaction Protocol), WSP (Wireless Session Protocol). ) Etc. are used.

  The mail processing system 231 processes the MMS message as follows. For example, when the MMS relay device 232 of the mail processing system 231 receives the MMS message transmitted by SMTP from the user terminal device 10S on the transmission side, the MMS relay device 232 transfers the received MMS message to the MMS server device 233. The MMS server device 233 stores the MMS message received from the MMS relay device 232 in the mail box 233a. Further, when the MMS message is stored in the mailbox 233a of the MMS server device 233, the MMS relay device 232 sends the WMS Push to the receiving user terminal device 10R via the PPG server 237 and the SMSC 250 at a predetermined timing. An incoming notification of the MMS message is transmitted, or a delivery confirmation notification of the MMS message is transmitted to the user terminal device 10S on the transmission side by WAP Push. Further, upon receiving a message acquisition request from the receiving user terminal device 10R, the MMS relay device 232 acquires the entire MMS message corresponding to the message acquisition request from the MMS server device 233, and a predetermined format as necessary. The conversion is performed and transmitted to the user terminal device 10R on the receiving side by IMAP. Also, when the MMS relay apparatus 232 receives an MMS message addressed to the user terminal apparatus 10R from the Internet 30, it performs a predetermined format conversion as necessary after performing an incoming call notification, and receives the user terminal apparatus 10R on the receiving side. MMS message is transmitted to IMAP.

SMTP can be used as a communication protocol when transmitting or transferring an MMS message from each user terminal device 10S, 10R. Then, the transmission of the MMS message to be transmitted is added to the “MAIL FROM” command which can be used in SMTP so that the user terminal devices 10S and 10R can transmit the MMS message by using the mail addresses of the plurality of lines. Line identification information that can identify the original line is written. For example, when the transmission source telephone number (MSISDN) of the MMS message to be transmitted is “0A0CDEFGHJK / TYPE = PLMN”, a “MAIL FROM” command having the following format including the telephone number information as line identification information: Is transmitted from the user terminal device to the mail processing system 231.
[Example format of MAIL FROM command]
MAIL <SP> FROM: <SP><0A0CDEFGHJK / TYPE = PLMN><CR><LF>

In addition, in the “RCPT TO” command that can be used in SMTP when an MMS message is transmitted or transferred, circuit identification information that can identify the transmission destination line of the MMS message to be transmitted is written. For example, when the transmission destination telephone number (MSISDN) of the MMS message to be transmitted is “0B0LMNOPQRS / TYPE = PLMN”, the “RCPT TO” command having the following format including the telephone number information as line identification information: Is transmitted from the user terminal device to the mail processing system 231.
[RCPT TO command format example]
RCPT <SP> TO: <SP><0B0LMNOPQRS / TYPE = PLMN><CR><LF>

Further, WAP Push can be used as a communication protocol when transmitting the incoming notification of the MMS message, the message body, and the delivery confirmation notification to the user terminal devices 10S and 10R as the push-type message described above. Then, in each of the user terminal devices 10S and 10R, in order to receive and process an incoming notification or the like by properly using the above-mentioned multiple line mail addresses, in a plurality of types of header fields of push-type messages transmitted and received by WAP Push, Line identification information that can identify the transmission destination or transmission source line of the MMS message is written. When transmitting the incoming notification of the MMS message and the message body, line identification information capable of identifying the transmission destination line of the MMS message to be received is written. On the other hand, when transmitting a delivery confirmation notification of an MMS message, line identification information capable of identifying the transmission source line of the MMS message to be transmitted is written. For example, when the destination of the incoming notification target MMS message and the destination of the delivery notification target MMS message are the mail addresses of the main line (A line), a predetermined value is set in the following header field: Written.
[Example of header for main line (A line) mail address]
Content-Type: application / vnd.wap.mms-message
X-Wap-Application-Id: x-wap-application: mms.ua

On the other hand, when the destination of the incoming notification target MMS message and the source of the delivery notification target MMS message are the mail addresses of the sub-line (B line), a predetermined value is set in the following header field: Written.
[Example of header in case of mail address of secondary line (B line)]
Content-Type: application / vnd.zzz.mid2
X-Wap-Application-Id: x-yyy-zzz: mid2.ua

Further, after each user terminal device 10S, 10R receives an incoming call notification, the entire MMS message is acquired, and mail-related processing (server processing) such as message list acquisition and message deletion for the mailbox 233a of the mail processing system 231 is performed. As a communication protocol when making a request, IMAP can be used. Then, in order to be able to request mail-related processing by properly using the mail addresses of the above-mentioned multiple lines in each of the user terminal devices 10S and 10R, the “NOOP” command usable in IMAP corresponds to the mail address to be processed. The line identification information capable of identifying the line to be written is written. For example, when the telephone number (MSISDN) of the line corresponding to the mail address to be processed is “0A0CDEFGHJK”, the “NOOP” command in which the telephone number information is written in the mid tag as the line identification information is as follows: The user terminal device transmits the mail processing system 231.
[NOOP command format example]
tag <SP> NOOP <SP><cmd> C-ID </ cmd><ua-prof> URI </ ua-prof><user-agent> UA </ user-agent><mid> 0A0CDEFGHJK </ mid><CR><LF>

  In the format example of the NOOP command, “C-ID” is a command ID for identifying an operation, and “URI” (Uniform Resource Identifier) is an HTTP server to which User Agent Profile (performance information of the user terminal device) is disclosed. “UA” (User Agent) is the name of the user terminal device.

  In addition to IMAP, LMTP (Local Mail Transfer Protocol) is used as necessary as a communication protocol for transmitting and receiving MMS messages and the like between a plurality of mail processing systems at different sites. For example, when an MMS message is transmitted from an MMS server device in a mail processing system to an MMS relay device at another site, IMAP is used, and an MMS message is transmitted from the MMS relay device in the mail processing system to an MMS server device at another site. Sometimes LMTP can be used.

  Next, a mail transmission process for transmitting a mail (MMS message) in the user terminal device 10 having the above configuration will be described. When the operation mode set in the user terminal device 10 is the single mode of the A mode or the B mode, mail transmission is executed on the usage line according to the set operation mode. On the other hand, when the operation mode set in the user terminal device 10 is the dual mode, mail transmission is executed according to the use line displayed when the mail is created. During mail transmission, the information on the used line may be displayed on the screen during transmission as shown in FIG.

  When the setting for using multiple lines in which neither the single mode nor the dual mode is selected is OFF, mail transmission is executed on the main line. However, if mail (MMS message) stored on the sub line (B line) is sent directly to the draft folder, sent mailbox, and unsent mailbox without being re-edited, it will be sent on the main line (A line). And the user may select whether to transmit.

FIG. 10 shows a plurality of transmissions of only the main line (A line) or only the sub line (B line) from the transmission-side user terminal device (UE) 10S operating in the single mode of the A mode or the B mode. It is a sequence diagram which shows an example of the mail transmission process procedure which transmits mail. The numbers in circles or the numbers in parentheses indicate the order of steps in the processing procedure (the same applies to the following sequence diagrams).
(7) 250 OK + Message-ID for the first mail transmission, as in the existing multiple mail transmission sequence, when the main line specified for the mail to be sent is only the main line or only the sub line. After receiving from the mail server, the second mail transmission process is started without disconnecting the TCP session. The second and subsequent mail transmission processing starts from (3) MAIL FROM transmission.

FIG. 11 shows that each mail is transmitted in a state in which a plurality of mails originating from two lines (main line and sub line) are mixed from the transmitting-side user terminal device (UE) 10S operating in the dual mode. It is a sequence diagram which shows an example of the mail transmission processing procedure to do.
When multiple emails are sent, if the main line (A line) and the secondary line (B line) are mixed as the use line specified for the email to be sent, it is different from the multiple email sending process on a single line. The mail is transmitted by dividing the TCP session. First, the user terminal device 10S transmits only a plurality of main line (A line) mails in the same sequence as in the single mode (FIG. 10), and once closes the TCP connection. Thereafter, the TCP connection is opened again, and mail transmission processing is performed for mails on a plurality of sub lines (B lines). When mail is transmitted in a state where mail on the main line (A line) and mail on the sub line (B line) are mixed, a sending screen is displayed for each line of the mail being sent as shown in FIG. You may make it display.

  A specific operation will be described in detail. The user terminal device 10S is provided with an address book of mail transmission destinations, and individual transmission destination addresses are registered. In these addresses, an attribute for designating whether to transmit on the main line or the sub line in the user terminal device 10S is set. For convenience of explanation, an address book record of the user terminal device 10S is exemplarily shown in Table 3.

  In Table 3 above, “destination name” indicates the name, name, and the like of a transmission destination (incoming side) user. “Attribute” defines whether the user terminal device is for communication on the main line or for communication on the sub line. In other words, the one designated by “A” is the other party to be sent by the main line mail address, and the one designated by “B” is the other party to be sent by the sub line mail address. What is designated by “D” indicates that the other party can be designated by any mail address.

In this case, in specifying the mail address in the dual mode in this embodiment, any address can be specified regardless of the attributes “A” and “B”. This example is as follows.
Address (TO :) [Sho Aikawa; Jiro Akagawa; Ken Watanabe] (Multiple choices)

  On the other hand, “A” mode address is sent to “Aikawa Sho”, “B” mode address is sent to “Jiro Akagawa”, and “Watanabe Ken” is sent to any user's desired address. Must be specified as original (FROM).

Therefore, in the present embodiment, based on the attribute information defined in the address book, the transmission source information to be specified is quoted, and the mail is transmitted separately by the protocol. That is, in this example, the transmission source is designated as follows.
TO: [Sho Aikawa] FROM: [business@aaa.jp]
TO: [Jiro Akagawa] FROM: [praivate@bbb.jp]
TO: [Ken Watanabe] FROM: ["Individual selection with prior user settings or TO: designation"]

  As described above, when the address designation is designated and executed by the mail application of the user terminal device 10S and the “send” operation is performed based on the instruction such as the user operation, the A / B mode is controlled by the protocol control shown in FIG. Communication takes place.

  For example, the transmission result display for notifying the result of the mail transmission is performed as follows. Sending results when sending multiple emails When sending multiple emails for only the main line (A line) or multiple emails for only the secondary line (B line), the transmission results are displayed in the same way as for normal multiple email transmission. To do. However, in the dual mode, the transmission line is displayed. For example, as shown in FIG. 13, the mail transmission including the main line (A line) mail and the sub line (B line) mail is successful at the timing when the transmission process of the main line (A line) is completed. The transmission result is not displayed regardless of the failure, and the display is performed by dividing the tag on each line at the end of the transmission process of the sub line (B line).

Further, in the transmission of the plurality of mails, the mail transmission process may be terminated when the user cancels the mail during the mail transmission or when the PDP communication is disconnected. Also, when the same cancellation or disconnection occurs during the transmission of the main line (A line) mail in the mail transmission process in which the main line (A line) mail and the sub line (B line) mail are mixed. The mail transmission process on the sub line (B line) may not be performed. When an error response is returned to the SMTP command from the mail server (MMS-R) during mail transmission, or when a timeout occurs in the user terminal device 10S, one of the following processes is executed. It may be.
・ Perform TCP Connection Close and Re-Open to send the remaining mail.
-Do not send the rest of the mail, perform TCP Connection Close, and end the sending process.

  Next, a mail reception process for receiving a mail (MMS message) in the user terminal device 10 having the above configuration will be described. When the operation mode set in the user terminal device 10 is the single mode of the A mode or the B mode, the incoming mail operation on the line different from the line being set (hereinafter referred to as “back line”) Perform according to ON / OFF of line mail notification setting. For example, if the backline mail reception notification setting is “OFF”, the mail addressed to the backline, the incoming notification message (M-Notification.ind), and the delivery notification message (M-Delivery.ind) are received in the background. No incoming notification operation is performed. However, when an e-mail addressed to the line being set is received, an incoming call notification operation similar to that when a normal e-mail is received may be performed. Also, when the back line mail reception notification setting is “ON”, when a mail addressed to the back line is received, the new mail pictogram is turned on, but other mail arrival notification operations may not be performed. In addition, the mail addressed to the back line can be viewed for the first time when switching to single mode or dual mode with the corresponding back line used as a use line, regardless of whether it is displayed in text or list. You may do it. When this switching is performed, an incoming call notification screen (a so-called information screen displayed on a standby screen or the like) is displayed, but other incoming operations may not be performed.

  When the operation mode set in the user terminal device 10 is the dual mode, information on the used line may be displayed on a receiving screen such as a continuous reception or an incoming mail screen.

  In addition, when the setting for using multiple lines where neither single mode nor dual mode is selected is OFF, incoming notification messages and delivery notification messages addressed to the secondary line (B line) can be received, but have already been received. May be continued from the incoming notification message, or the mail operation to the mail server (MMS-R) may be suppressed. At that time, on the UI (user interface) such as a display, the user may be notified that the above message cannot be received because the setting for using multiple lines is OFF. If the user selects reply or transfer, the mail creation screen may be activated after notifying the user that the main line (A line) is fixed because the setting for using multiple lines is OFF. .

FIG. 14 shows a plurality of destinations of only the main line (A line) or only the sub line (B line) in the user terminal device (UE) 10R on the receiving side operating in the single mode of the A mode or the B mode. It is a sequence diagram which shows an example of the mail reception process procedure which receives mail.
When receiving multiple emails simultaneously for incoming notification messages (M-Notification.ind) in the user terminal device 10R, only the email addressed to the main line (A line) or the sub line (B line) In the case of only the mail addressed, the second mail reception process is started without disconnecting the TCP session after receiving the STORE command response to the first mail reception as in the existing multiple selection reception sequence. The second and subsequent mail reception processing starts from FETCH RFC822.SIZE.

FIG. 15 shows that the receiving side user terminal device (UE) 10R operating in the dual mode receives each mail in a mixed state of a plurality of mails that are transmitted from two lines (main line and sub line). It is a sequence diagram which shows an example of the mail reception process procedure to do.
When receiving a plurality of incoming notification messages (M-Notification.ind) in the user terminal device 10R at the same time, mail addressed to the main line (A line) and sub-line (B line) When mails are mixed, unlike TCP multiple mail reception processing on a single line, the TCP session is divided and received continuously. First, the user terminal device 10R receives only the mail addressed to the main line (A line) in the same sequence as in the single mode (FIG. 14), and once closes the TCP connection. Thereafter, the TCP connection is opened again, and the reception process is continued for the mail addressed to the sub line (B line).
Note that when receiving mail in a state where mail addressed to the main line (A line) and mail addressed to the sub line (B line) are mixed, as shown in FIG. The reception screen may be displayed by dividing the display by tags.

  The reception result display for notifying the result of the mail reception is performed as follows, for example. When receiving multiple e-mails only for the main line (A line) or multiple e-mails only for the secondary line (B line) for the receiving screen when receiving multiple e-mails Is displayed. However, in the dual mode, the line being received is displayed. In addition, when mail addressed to the main line (A line) and mail addressed to the sub line (B line) are mixed, for example, as shown in FIG. 17, mail addressed to the main line (A line) The reception result is not displayed regardless of success or failure at the timing when the reception process is completed, and is displayed at the end of the reception process of the mail addressed to the sub line (B line).

In the reception of the plurality of mails, the reception process may be ended when the user cancels the mail while receiving the mail or when the PDP communication is disconnected. In addition, in the mail reception process in which mail addressed to the main line (A line) and mail addressed to the secondary line (B line) were mixed, the same cancellation or communication disconnection was performed while mail addressed to the main line (A line) was being received. At this time, the reception processing of the mail addressed to the sub line (B line) may not be performed. When an error response is returned to the IMAP command from the mail server (MMS-R) during mail reception, or when a timeout occurs in the user terminal device 10R, one of the following processes is executed. It may be.
-Perform TCP Connection Close and Re-Open to receive the remaining mail.
・ Receive the remaining mail, do TCP Connection Close, and end the receiving process.

  As described above, when the destination designation at the time of transmission is mixed in each mode attribute, and by adopting the method of receiving mail for each line type at the time of reception, the user is forced to perform a special operation. In addition, the mail application operation can be easily controlled, a stable system operation can be obtained, and communication traffic can be suppressed.

Further, the display of the mail destination and the sender information may be performed as follows. For example, when displaying a mail in which the mail addresses of registrants whose address book attributes are “A” and “B” are mixed in “From”, “To”, and “Cc” of the mail, for example, the following (1) And display according to the rules of (2). The address book attribute is an address book attribute item provided for designating which operation mode is displayed in the address book when it is set. For example, a registrant whose address book attribute is “A” is displayed in the address book when the A mode is set, and a registrant whose address book attribute is “B” is displayed as the address book when the B mode is set. Is displayed.
(1) When the single mode is set, the mail address information in the address book in which the address book attribute corresponding to the back line other than the line being set is registered is not displayed.
(2) When dual mode is set, or when setting for using multiple lines is OFF, the mail address information in the address book is used regardless of whether the address book attribute is “A” or “B”. Is displayed.

  In addition, new mail inquiry processing may be controlled as follows. For example, when the single mode is set, control may be performed so that only new mail inquiries on the line according to the set operation mode (A mode or B mode) can be executed. On the other hand, when the dual mode is set, the user can select an inquiry target from “main line (A line)”, “sub line (B line)”, and “all” after selecting a new mail inquiry. You may control. Here, when “All” is selected and executed, as in the case of sending and receiving multiple emails, after inquiring new mail for the main line (A line), once TCP Connection Close is performed, and then TCPConnection Open is performed again. It is also possible to control so that a new mail is inquired about the sub line (B line). In addition, when the setting for using a plurality of lines is OFF, it may be controlled so that only new mail inquiries can be performed on the main line (A line).

  Further, the server mail operation for operating the mail in the mail server from the user terminal device 10 may be processed as follows. For example, when the user terminal device 10 is set to the single mode, control may be performed so that only the server mail operation of the line according to the operation mode (A mode or B mode) being set can be performed. Good. On the other hand, when the dual mode is set, as shown in FIG. 18, after the user selects the server mail operation, the server mail operation is selected for the main line (A line) or the sub line (B line). You may control so that it may be possible. If the setting for using multiple lines is OFF, control may be performed so that only server mail operations can be performed on the main line (A line). The server mail list and the server mail capacity are held for each of the main line (A line) and the sub line (B line).

  Of the above server mail operations, the server mail transfer is the mail to be transferred regardless of whether the transfer is from the incoming notification message (M-Notification.ind) or from the server mail list. Specifies the mailbox line where is stored. If the setting for using multiple lines is OFF, server mail transfer on the secondary line (B line) may be suppressed.

  Further, when a plurality of server mails are deleted simultaneously for an incoming notification message (M-Notification.ind) in the user terminal device 10, the mail to be deleted is only addressed to the main line (A line) or the sub line (B In the case of only addressed to (line), all UIDs (message identifiers) to be deleted may be specified in the STORE command, as in the server mail deletion sequence for a plurality of existing mails. In addition, when the mail to be deleted includes mail addressed to the main line (A line) and mail addressed to the secondary line (B line), as shown in FIG. Specify only the mail in the STORE command, and after receiving the response code from the mail server, perform TCP Connection Close once. After that, TCPConnection Open may be performed again, and server mail deletion processing may be performed for mail on the sub line (B line). If the setting for using multiple lines is OFF, server mail deletion for mail addressed to the secondary line (B line) may be suppressed.

Further, in the server mail deleting process for the plurality of mails, the server mail deleting process may be ended when the user cancels the mail or when the PDP communication is disconnected. In addition, in mail deletion processing in which mail addressed to the main line (A line) and mail addressed to the sub line (B line) were mixed, the same cancellation or communication disconnection was performed while deleting the mail on the main line (A line). At this time, the deletion process of the sub line (B line) may not be performed. Also, if an error response is returned from the mail server (MMS-R) to the IMAP command while deleting the mail, or if a timeout occurs in the user terminal device 10R, one of the following processes is executed. You may make it do.
・ Perform TCP Connection Close and Re-Open to delete the remaining mail.
-Do not delete the remaining mail, perform TCP Connection Close, and end the deletion process.
