When mail creation is selected from the input means 5 (the screen display after the selection is shown in FIG. 6A) and the item <E-mail / simple E-mail> is further selected, as shown in FIG. 6B. The mail text creation screen is displayed on the display unit (S10). The control unit 16 confirms whether a signature is set in the signature storage unit 13b (S11), and if there is a signature, confirms the number of characters of the signature stored in the signature storage unit 13b (hereinafter, confirmation The number of characters in the signature is "Y") (S
12). Further, the control unit 16 takes out the number A of characters that can be input by the simple e-mail from the number-of-characters storage unit 13a, and displays a value X (X = A−Y) obtained by subtracting the number of signature characters Y from this A on the display unit 14 (S13). Further, the control unit 16 controls the character number storage unit 13
The value B (Z = BY) obtained by subtracting the number of signature characters Y from the number B of characters that can be input by e-mail from a is displayed on the display unit 14.
(S14). Here, the display unit 14 when the type "Hello", as the lower column in FIG. 6 (b) X
And Y values are displayed. Specifically, the display of E2038 is the number of characters that can be input by email, the display of E207 is the number of characters that can be input by simple email, and how many more characters can be input from the input unit (2038 characters for email, (207 characters for simple email)
Is shown. Note that one half-width character is counted as one character, and full-width character is counted as two characters.

On the other hand, when the signature is not set in the signature storage unit 13a, the control unit 16 controls the character number storage unit 13a.
The simple e-mail inputtable character number A and the e-mail inputtable character number B are taken out from these and displayed on the display unit 14 as X and Y, respectively (S15, 16).

In this way, the remaining amount of characters that can be input is displayed for each of the E-mail and the simple E-mail, and the user can visually and easily grasp how many characters can be input while inputting the characters. Is possible.

Next, the control unit waits until there is an instruction from the input unit 15 for character input or title setting (S17, S1).
8) If there is a character input, subtract the number of characters C of the input character from the number of simple e-mail enterable characters X and the number of e-mail enterable characters (X = X−C, Z = Z−C) (S
19, S20). When the number X of characters that can be input by simple email has become smaller than 0 (S21), the display of the number of characters that can be input by simple email is terminated (S22). When the number of characters Z that can be entered in E-mail is smaller than 0 (S2
3), display indicating that the number of characters is exceeded (Fig. 6 (f))
Is displayed on the display (S24), and when the input character is deleted (S25), Z = Z + D (D is the number of deleted characters)
As (S26), the Y value and the Z value are displayed on the display unit (S27).

When a title setting instruction is given (S18),
The subject input screen display (FIG. 6 (c) is the screen when "Contact" is input in the subject input screen display) is displayed on the display unit 14 (S28), and the email subject character limit number W is extracted from the character number storage unit. , X value and W value are displayed on the display unit 14 (S29, S30).

Next, it is confirmed whether or not the destination setting has been designated and the characters have been input (S31, S32). However, since the subject must always have one or more characters, this destination instruction is confirmed only when one or more characters are entered in the subject. When there is a character input, the number C of input characters is recognized, and values obtained by subtracting C from the values of X and W are displayed on the display unit 14 (S33, S34). When the value of X obtained by subtracting the input character number C becomes smaller than 0 (S35), the display unit of the simple email inputtable character number X on the display unit 14 is terminated (S36). Next, when the value of X obtained by subtracting the input character number C becomes smaller than 0 (S37), a display indicating that the character number is exceeded (FIG. 6 (f)) is displayed on the display unit ( S38) If the input character is deleted (S39), W = W + E (E is the number of deleted characters) (S40), and the value of W and the value of X (display is not completed in S36) (Only in case) is displayed on the display unit (S41).

If there is a destination setting instruction (S31),
The destination input screen display (FIG. 6D) is displayed on the display unit 14 (S42) when the destination is displayed as "p-taro@ΔΔΔ.jp". If there is a destination input and a transmission instruction (a mode is selected and a transmission instruction is issued according to the transmission mode of FIG. 6E) (S43, S44), whether the value of X is smaller than 0 or not. (S4
5) If the value of X is smaller than 0, the content of the email created with the email type of email is sent to the email server for email using the second email sending means (S).
47). When the value of X is 0 or more, it is determined whether there are a plurality of destinations (S46). When there are a plurality of destinations, the email type is used as the email and the content of the created email is the second email processing means 16b. Is used to send a mail server for E-mail (S45), and when there is one destination, the contents of the mail created as a simple E-mail type is sent to the mail server of the center using the first mail processing means ( S4
8).

By switching the type of mail depending on the number of characters input as described above, IS
If the number of characters that can be transmitted using the UUI used at the time of setting up a DN is used, the voice (B) channel is not used, and the mail transmission cost is lower than the mail transmission using the normal B channel. On the other hand, the user of the mobile wireless terminal device 10 does not need to bother to select the email or the simple email from the beginning and then start to enter the contents of the email, and thus the simple email is not required. Even if you want to enter more than the limit number of characters after selecting, or if you select E-mail and it is cheaper to send it by simple E-mail because the number of input characters is less, it is bothersome. It is not necessary to reselect the type of mail, and since the number of characters that can be input is displayed on the display unit, it is possible to provide a portable wireless terminal device capable of sending mail that is extremely easy for users to use. .

In this embodiment, after selecting E-mail / simple E-mail, whether to send the e-mail or simple E-mail is selected depending on the number of characters and the number of recipients. If a mail is selected and the number of characters is less than or equal to a predetermined number of characters and there is only one destination, the simple email may be automatically transmitted. Alternatively, if the simple email is selected, the number of characters is greater than or equal to the predetermined number of characters or the number of destinations is more than one. In this case, the e-mail may be transmitted.

Even if there are one or more destinations, if it is cheaper to send by simple email than by email if the number of destinations is a predetermined number of destinations, the number of destinations is within a predetermined number. In some cases, a simple e-mail may be sent. In this case, it is possible to send the simple e-mails to a plurality of destinations by sending the simple e-mails for each of the destinations as many as the destinations.

If the destination of the e-mail sent as the simple e-mail is not set and registered in the simple e-mail server (center), it is processed by sending it to the normal e-mail server. Become.

It should be noted that, in the above, when the center side allows a plurality of destinations of the simple email, the simple email can be transmitted once to the plurality of destinations.

The operation in the case of sending a simple e-mail will be described below with reference to FIGS. 2, 7 and 8. Figure 7
In the case of transmitting a simple e-mail, the first mail transmission / reception means 16a of the mobile wireless terminal device 10 transmits data from the wireless transmission / reception unit 12 to the center 30 via the wireless base station 20a.
The call is set to (S1). The ISDN call setup message is configured as shown in FIG. 8, and 128-octet information can be transmitted as user-user information (UUI). The contents of the simple email are UU
As described in the flow charts of FIGS. 3 to 5, which will be written in I, the mail content is not cut off in the middle by selecting it as a simple e-mail only when the characters are less than a predetermined value. You will be able to send everything.

After the call is set, a call disconnect message is sent to disconnect the communication with the center (S2). The center receiving the simple e-mail can communicate with the portable wireless terminal device, which is the destination of the simple e-mail, that is, if the center exists in the wireless zone of the wireless telephone network and is in the communicable state,
UUI portion of the call setup message received in S1 (simple E
The contents of the mail) are transmitted as they are to the destination portable wireless terminal device as the UUI of the call setting message (S3). When the transmission of the call setup message is completed, a call disconnection message is transmitted to disconnect the communication (S4). If the destination mobile wireless terminal device is not set and registered in the mail server of the center, it cannot be sent. Therefore, by sending it to the e-mail server, the user mistakenly sends the e-mail destination address to the simple e-mail. Even when the e-mail is set as the destination address of the mail, the sent e-mail can be properly processed without burdening the user. Also,
If a destination address that is not registered is sent,
The center side may reject the reception, the center side transmits the unregistered destination address to the mobile wireless terminal device that has transmitted the e-mail, and the mobile wireless terminal device side displays that fact. You may make it notify a user.

By transmitting the mail using the UUI portion of the call setup message as described above, the mail communication charge is lower than that of the normal E-mail using the B channel. Since the UUI portion of the call setup message has a limited amount of information, if the simple email can be sent and received twice or three times by the same procedure, the amount of information that can be sent is expanded. Can be facilitated. Specifically, the next UU is added to the UUI part to be transmitted the first time.
By including the mail number information in I as well, the receiving side analyzes it and determines the same sender and subsequent information by the call processing message, thereby expanding the amount of information that can be sent and received. be able to.

Similarly, the UUI is similarly applied to the call disconnect message.
Therefore, if the child disconnection message is added with the contents of the mail and sent,
It is possible to transmit information of 128 × 2 octets by one operation, which is advantageous in terms of time and cost.
