Description

  The present invention relates to e-mail, and more particularly to a quote reply technique.

  When replying to a mail received by mail software such as a personal computer, the received mail text may be included in the text of the mail, and the mail may be clearly indicated to the other party. This is generally referred to as a quote reply, and when the reply mail for the received mail is written in advance by setting in the mailer, the body of the automatically received mail is described in the mail body You can write a reply from

There is a technique described in Patent Document 1 for performing a reply to quote, and according to the technique described in the Patent Document, a technique for creating a mail by quoting only the text by deleting the signature of the received mail. Is disclosed.
JP 2001-142808 A

  However, in the case of a mobile phone, this quote reply is limited in the number of characters in the body (for example, within 10,000 characters), so using the quote reply will contain the content of the original mail text, and this will reduce the number of characters. . Therefore, in the case of a mobile phone, it is not preferable to describe the contents of the original mail in the text. In addition, depending on the service provided, there is a service that determines the communication cost based on the data capacity of the mail. A quote reply that increases the data capacity due to the length of the text may increase the communication cost.

  Therefore, in the present invention, the mail is a reply mail to a certain mail, and the contents of the original mail can be presented to the user even if the contents of the original mail are not described in the contents of the body. The purpose is to provide a telephone.

  In order to solve the above-described problem, a mobile phone according to the present invention includes a storage unit that stores a transmission mail transmitted by itself, a reception unit that receives a mail including specific information that identifies the transmission mail, and the reception unit. The specifying means for specifying the transmitted mail stored in the storage means and the body of the mail received by the receiving means are specified by the specifying means based on the specifying information of the mail received by the receiving means. And a display means for displaying the text of the transmitted mail together.

By having this configuration, the mobile phone can send outgoing mail that is related to the received mail based on the data of the received reply mail, such as the address and subject, etc. Can be read and displayed with the received mail.
By doing this, even if the content of the original email is not described in the body of the received reply email, the mobile phone knows the content of the original email and what kind of content the reply is for Can be notified to the user.

Further, since the body of the original mail is not quoted in the body of the reply mail, the data capacity is not increased correspondingly and the communication cost is not increased.
In addition, the mobile phone according to the present invention further includes a transmission unit that transmits each transmission mail with a unique identifier as the specific information when transmitting the transmission mail, and the storage unit includes each transmission mail and Each unique identifier is stored in association with each other, the receiving means receives a mail with the same identifier as that assigned by itself, and the specifying means adds an identifier attached to the mail. The corresponding outgoing mail may be specified.

By providing this configuration, an identifier is attached to the outgoing mail sent by the device, and this identifier is attached to the reply mail, so it is possible to easily identify which outgoing mail is the reply, , It can be displayed together with the received mail.
In the mobile phone according to the present invention, the identifier may be a Message-ID attached to a header portion of a transmission mail, and may include at least information related to a transmission time of the transmission mail.

With this configuration, the mobile phone can specify the outgoing mail using the Message-ID (Message-IDentifier) of the mail sent by itself. Conventionally, mail software may be transmitted with a Message-ID, and the present invention can be realized by applying the Message-ID, and can promote a reduction in development cost and development time.
Further, in the mobile phone according to the present invention, the storage means further stores a received mail identifier attached to the received mail received by the receiving means and a text, in association with each other, and the transmitting means is the own device. When the transmitted mail to be transmitted is a reply to the received mail, the received mail identifier attached to the received mail is attached to the transmitted mail and transmitted, and the specifying means is further specified by the specifying means If the sent mail includes the received mail identifier, the received mail is specified based on the received mail identifier, and the display means further displays the text of the received mail specified by the specifying means That's good.

With this configuration, the mobile phone sequentially follows the identifiers one by one with respect to mails that have been sent back and forth, such as reply mails to reply mails and reply mails to reply mails, with a communication partner. You can check the contents of past emails.
Even when the user forgets the contents of the past mail, the contents of the past mail are displayed so that the user can remember the contents.

Further, in the mobile phone according to the present invention, the specific information is a mail address of a transmission source of the mail received by the receiving unit, and the specifying unit stores the mail transmitted to the device having the address by itself. Of these, the email sent at the latest time may be specified.
With this configuration, it becomes possible to search for the original mail based on the date of the address of the other party of the received mail and the mail transmitted by the own machine. In this case, the Message-ID is more uncertain than when Message-ID is used. It is possible to reduce the data capacity of the header to which the Message-ID is attached compared to the case of using it.

  In addition, a display method for displaying a transmission mail corresponding to a reply mail on a mobile phone, based on a storage step of storing information of the transmission mail transmitted by the own device, a reception step of receiving the mail, and the received mail And a display step for displaying the text of the transmitted mail specified in the specifying step together with the specifying step for specifying the transmitted mail stored in the storing step and the text of the mail received in the receiving step. Steps may be included.

First, the mobile phone 100 checks whether or not there is a past mail display request from the user (step S801). If there is no display request (NO in step S801), the process returns to step S801 and waits for input from the user.
When the past mail is displayed from the user (YES in step S801), the control unit 160 next checks whether there is In-Reply-To in the header of the mail displayed in the past mail body area. Detection is performed (step S803).

If there is an In-Reply-To (step S803), a mail having a Message-ID column in which the message ID described in the In-Reply-To is stored is stored in the storage unit 150 of the own device. It is searched whether it has been done (step S805).
If there is a mail corresponding to In-Reply-To (step S805), the body of the mail is read and displayed in the past mail display area.

If there is no In-Reply-To in the displayed past mail (NO in Step S803), or if there is no mail corresponding to In-Reply-To (NO in Step S805), “Past Mail An error message is displayed (step S809).
Then, it is checked whether or not an input for ending the mail display from the user has been made (step S811). If there is no input to end (NO in step S811), the process returns to step S801 to execute the subsequent processing. When the end input is made (YES in step S811), the mail display is ended.

The above is the operation of the mobile phone 100 in the second embodiment.
It should be noted that the input of the browsing request for the past mail can be realized by simply pressing the left key of the direction key when browsing the reply mail. This may be done by selecting a command “browse past mail” in a menu item called by calling a menu when viewing a reply mail.
