The operation of each part of the mobile communication terminal 1 is controlled. In the present embodiment, the mail destination creation unit 20 is realized inside the control unit 2 by the CPU executing a mail destination creation program stored in the ROM.

  The mail destination creation unit 20 attaches the name and mail address registered in the acquired phone book data 5 to the header of the electronic mail as a destination. The RAM of the control unit 2 is used as a work memory when the CPU executes a program.

  The input unit 3 includes, for example, a cross cursor key, an alphanumeric key for inputting numbers and characters, a button for designating a function, and the like. The user operates the input unit 3 to A desired sentence can be created.

  The display unit 4 is composed of, for example, a liquid crystal display (LCD) or the like, and displays an image or the like for executing various operations by the mobile communication terminal 1. The display unit 4 displays, for example, a sentence being created.

  The phone book data 5 is data indicating the destination of an e-mail or a short message, and a plurality of types of the phone book data 5 are stored in a nonvolatile memory (not shown). Thereby, the non-volatile memory functions as a telephone directory.

  As shown in FIG. 2, the telephone directory data 5 in the present embodiment is registered in association with a name, a telephone number, a mail address, and the like, and among these, an e-mail destination is specified by a mail address. Can do. Further, it can also be determined whether or not a short message can be transmitted.

  Specifically, if the domain name specified from the own mail address and the destination mail address is the same, the mobile communication terminal 1 and the destination mobile communication terminal 1 have the same communication business. It is determined that the short message can be transmitted as being provided by the user.

  In addition, among those registered in the telephone directory data 5, the destination of the short message can be specified by the telephone number.

  Based on an instruction from the control unit 2, the phone book search unit 6 searches the phone book data 5 for a mail address corresponding to the phone number or searches for a phone number corresponding to the mail address.

  The mail data 7 is data indicating an electronic mail created by the EM body creation unit 9E and the mail destination creation unit 20 and a short message created by the SM creation unit 9S, and is held in a volatile memory (not shown). Is. Thereby, the volatile memory functions as a mail data file.

  The mail character counter 8 counts the number of characters of an electronic mail or short message specified from the mail data 7 held in the volatile memory.

  The EM text creation unit 9E creates a text of an e-mail in HTML (Hyper Text Markup Language) format that can be transmitted via a network. In the present embodiment, the maximum number of input characters of an e-mail created by the EM text creating unit 9E is 5000 characters.

  The SM creation unit 9S creates a short message in a text format that can be transmitted to the mobile communication terminal 1 provided by the same carrier as the mobile communication terminal 1 of the SM. In the present embodiment, the maximum number of input characters of a short message created by the SM creation unit 9S is 50 characters.

  The EM transmission unit 10E performs error correction coding processing, mapping processing to a physical channel, and spreading processing on the email created by the EM body creation unit 9E and the mail destination creation unit 20, and then transmits the wireless unit 11 is supplied.

  The SM transmission unit 10S performs error correction coding processing, mapping processing to a physical channel, and spreading processing on the short message created by the SM creation unit 9S, and then supplies the short message to the radio unit 11.

  The radio unit 11 performs D / A (Digital-Analog) conversion processing and modulation processing on the e-mail supplied from the EM transmission unit 10E and the short message supplied from the SM transmission unit 10S, and then up-converts. Then, it is transmitted to the base station via the antenna 12.

  Next, a specific operation of the mobile communication terminal 1 having the above configuration will be described. FIG. 3 is a flowchart for explaining the details of the mail creation mode switching process executed by the mobile communication terminal 1. In this process, the user first selects either an e-mail or a short message as an outgoing mail service using the input unit 3 (step S1). Here, when an e-mail is selected (step S1; e-mail), the control unit 2 sets the e-mail creation mode, and then shifts to an e-mail creation process described later (step S2).

  On the other hand, when the short message is selected in the process of step S1 (step S1; short message), the control unit 2 displays the phone book (for example, a list of names) on the display unit 4 after setting the short message creation mode. The user is instructed to select a destination. In response to this, the user searches the telephone directory displayed on the display unit 4 (step S3), and detects the name of the person who sends the short message (step S4).

  When the user selects the name of the person using the input unit 3 (step S4; Yes), the control unit 2 controls the phone book search unit 6 to store the person from the non-volatile memory functioning as the phone book. The phone book data 5 is detected, and “phone number” registered in the phone book data 5 is acquired as a destination (step S5; Yes).

  In addition, the control unit 2 acquires the “mail address” registered in the phone book data 5, and whether the domain name specified from the own “mail address” and the “mail address” of the transmission destination is the same. By judging whether or not, it is judged whether or not a short message can be transmitted (step S6).

  If it is determined that transmission of the short message is impossible (step S6; No), a message to that effect is displayed on the display unit 4 for a predetermined period (step S7). The process proceeds to creation processing (step S2). On the other hand, when it is determined that the short message can be transmitted (step S6; Yes), the initial value “0” is set in the mail character number counter 8 (step S8).

  And after a character string is input by the kana character by the user (step S9; Yes) and converted into a kanji (step S10), when "confirm" is selected (step S11; Yes), the control unit 2 The determined number of characters is added to the value of the mail character number counter 8 (step S12). In this way, the control unit 2 can count the number of input characters.

  When the number of input characters does not exceed the maximum number of input characters (50 characters) of the short message (step S13; Yes, step S14; No), the processing of steps S9 to S12 is repeated, and then the creation of the short message is performed. When “send” is selected as the completion (step S14; Yes), the created short message is transmitted to the short message server of the communication carrier (step S15).

  On the other hand, when the number of input characters exceeds the maximum number of input characters of the short message (step S13; No), the short message creation mode is switched to the email creation mode, and a message to that effect is displayed on the display unit 4 for a predetermined time. After that (step S16), the telephone directory data 5 stored in the nonvolatile memory is searched using the telephone number acquired in the process of step S5 as a key (step S17), and the name corresponding to this telephone number And the mail address are acquired as destinations (step S18).

  Thereafter, when the “subject” is input by the user (step S19; Yes), the control unit 2 uses the input subject and the name and mail address acquired in the processing of step S18 in the header of the e-mail. sign up. Further, the control unit 2 reads the mail data 7 from the volatile memory storing the mail data file, and converts the mail data 7 from the text format to the HTML format (step S20). Subsequently, the control unit 2 switches the display screen of the display unit 4 from the display screen of the short message creation mode shown in FIG. 4A to the display screen of the email creation mode shown in FIG. Step S21).

  Then, after the character string is input by the user following the mail text that is converted into the HTML format and displayed on the display screen of the display unit 4 (step S22; Yes), it is assumed that the creation of the electronic mail is completed, and “send” Is selected (step S23; Yes), the created e-mail is transmitted to the telecommunications carrier's e-mail server (step S24).

The process so far is the mail creation mode switching process.
Next, details of the e-mail creation process that is the process of step S2 in the above-described mail creation mode switching process of FIG. 3 will be described. FIG. 5 is a flowchart showing the processing content of the e-mail creation process executed under the control of the control unit 2. In this e-mail creation process, as shown in FIG. 5, the control unit 2 first displays a “mail address” input screen on the display unit 4 (step S31).

  When the input of the mail address is completed by the user (step S32; Yes), the control unit 2 displays the “subject” input screen on the display unit 4 (step S33). Subsequently, when the input of the subject is completed by the user in accordance with the “subject” input guidance on the input screen (step S34; Yes), an input screen for the mail “text” is displayed on the display unit 4 (step S35).

  After that, after the character string is input by the user (step S36; Yes), when “transmission” is selected as the creation of the e-mail is completed (step S37; Yes), the control unit 2 uses the mail character counter 8 Is checked to determine whether or not the number of input characters is within the maximum number of input characters (50 characters) of the short message (step S38).

  When the number of input characters is within the maximum number of input characters of the short message (step S38; Yes), a message for confirming whether to transmit as an e-mail or change to a short message is displayed on the display unit 4. (Step S39).

  In response to this, when the user selects “short message” (step S40; Yes), the control unit 2 has the same domain name specified from its own “mail address” and the destination “mail address”. By determining whether or not there is, it is determined whether or not the short message can be transmitted (step S41).

  If it is determined that the short message can be transmitted (step S41; Yes), the electronic mail creation mode is switched to the short message creation mode, and the mail address input in the process of step S32 is used as a key. The telephone directory data 5 stored in the nonvolatile memory is searched (step S42), and if there is a telephone number corresponding to this mail address (step S43; No), it is acquired as a destination (step S44).

  Then, the control unit 2 reads the mail data 7 from the volatile memory functioning as a mail data file, converts the mail data 7 from the HTML format to the text format, etc., and converts the created email into a short message. Then (step S45), this short message is transmitted to the short message server of the communication carrier (step S15).

  On the other hand, when it is determined that the number of characters input in the process of step S38 exceeds the maximum number of input characters of the short message (step S38; No), the user directly uses “e-mail” in the process of step S40. If transmission is selected (step S40; No), if it is determined in step S41 that transmission of a short message is impossible (step S41; No), the mail address input in step S43 If the telephone number corresponding to is not detected (step S43; Yes), the control unit 2 transmits the created e-mail as it is to the telecommunication carrier's e-mail server (step S24).

The above process is an e-mail creation process.
As described above, the mobile communication terminal 1 according to the present embodiment creates an e-mail from the short message creation mode when the number of characters exceeds the maximum number of input characters (50 characters) of the short message during creation of the short message. The mode is switched, the mail data 7 is converted from the text format to the HTML format, and the name and mail address corresponding to the telephone number acquired as the short message destination from the telephone directory are acquired as the e-mail destination. As a result, the user can proceed to creation of an e-mail as it is without performing a complicated operation such as copying and pasting a short message document into the e-mail.

  Further, when the number of characters in the body of the e-mail that has been created is within the maximum number of input characters of the short message, the mobile communication terminal 1 can transmit the e-mail as it is or the short message according to the user's selection. Can be converted into a short message and transmitted. Thereby, even when changing to a short message, the user can transmit the created document as a short message without performing complicated operations such as copying the text of the e-mail and pasting it in the short message.

  As described above, the mobile communication terminal 1 can transmit a document by an optimal transmission method among short messages and e-mails without performing complicated operations. In addition, the user can create a short message or an e-mail without worrying about the number of characters.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the control unit 2 determines whether or not a short message can be transmitted based on an e-mail address. However, the present invention is not limited to this. Good. Specifically, the CDE code (fourth to sixth digits from the most significant digit) of the telephone number 090 (or 080) -CDE-FGHIK of the mobile communication terminal 1 consisting of 11 digits registered in the telephone directory data 5 is used. If the telecommunications carrier of the mobile communication terminal 1 of the other party is specified from the combination of numbers in the (digit)), and if it is the same as the telecommunications carrier of the mobile communication terminal 1 of itself, it is possible to transmit a short message. It may be determined that there is.

  In addition, the configurations of the telephone directory search unit 6, the EM creation unit 9E, the SM creation unit 9S, the mail destination creation unit 20 and the like according to the above embodiment can be realized by hardware, and the software of the control unit 2 It may be realized by processing. In this case, the control unit 2 is caused to function as the telephone directory search unit 6, the EM creation unit 9E, the SM creation unit 9S, the mail destination creation unit 20, and the like, and a program for realizing each of the processes described above is stored in the mobile communication terminal. 1 and the control unit 2 may execute such a program.
