In FIG. 1, a transmission / reception circuit unit 10 to which an antenna is connected is a circuit that performs transmission / reception processing in a mobile phone under the control of a control unit 12 having a microcomputer. That is, the transmission / reception circuit unit 10
The control unit 1 modulates an audio signal, data, control signal, or the like with a high frequency and sends it out of the antenna, or demodulates an audio signal, data, control signal, or the like received from the antenna, and
Output to 2.

The control unit 12 operates the operation keys 24 and the transmission / reception circuit unit 10 according to a program described in the ROM 14.
Operates in response to a control signal from the
It controls the D driver 18 and the voice processing unit 26 to perform call processing in voice communication. Further, the control unit 12 includes a RAM
The RAM 16 is used as a work area when the program described in the ROM 14 is executed.

The portable telephone shown in FIG. 1 is compatible with a text message mail service in which mail can be exchanged via the Internet, and the control unit 12 also performs processing relating to this service. That is, the control unit 12 performs a transmission process using a character message input by a predetermined key operation as an e-mail, and stores the received e-mail in the RAM 16.

The control unit 12 performs a process related to the mail service so that a malicious mail does not arrive.
A reject address registration process for registering a mail address that the user does not want to receive in the RAM 16 as a reject address is performed. Further, the control unit 12 also performs a received mail rejection process of automatically rejecting an e-mail registered as a rejected address upon reception. In the rejection address registration process, the control unit 12 determines both the telephone number and the address of the transmission source of the rejection address registration from the received data of the received character mail, and performs automatic registration by associating them. In FIG. 1, the ROM 14 and the RAM 16 are connected to the control unit 12.
However, the ROM 14 and the RAM 16 may be built in the control unit 12 or may be externally mounted.

An LCD driver 18 drives a display unit 22 which is an LCD under the control of the control unit 12, and controls the display of the display unit. That is, the LCD driver 18 stores character patterns (including numbers) and icon (graphic) patterns corresponding to the control signals from the control unit 12 in the font ROM 2.

Perform the following processing.

Referring to FIG. 2, there is shown a system configuration diagram of an electronic mail service system capable of exchanging electronic mail via the Internet. Here, since the capacity of the e-mail that the mobile phone can exchange is small, this e-mail service system is called a short message service system, and the e-mail is also described as a short message here.

Mobile station A and mobile station B in FIG.
The mobile phone shown in FIG. The base station (BS) 2 is a base station of the mobile station A and the mobile station B, and is connected to an exchange (MSC) 3 as an upper station thereof. The exchange 3 is an exchange that performs call connection processing, and is connected to a plurality of base stations 2 and to an integrated services digital network (ISDN) and a public switched telephone network (PSTN). The exchange 3 also has a short message service center (SMSC).
4 is connected.

[0015] The short message service center 4
This is a center that performs message management of the short message service by the mobile device A or the mobile device B. When the mobile station A or the mobile station B exchanges short messages, these mobile stations communicate with the service center 4. That is, for example, when a short message is sent from the mobile station A to the mobile station B, the mobile station A performs call processing to the base station 2 and communicates with the short message service center 4 via the base station 2 and the exchange 3. Then, a message is transmitted to the center 4.

When the message service center 4 receives the message, the message service center 4 performs a calling process to the exchange 3 and connects to the mobile station B via the exchange 3 and the base station 2 to short-circuit from the mobile station A. Send a message. The service center 4 is connected to an E-mail exchange 5 connected to the Internet.

FIG. 3 is a schematic diagram showing the data format of an electronic mail applied to the short message service system shown in FIG. The electronic mail is a short message composed of data 50 storing a text message and an E-mail address which is a mail address, and communication data 60 storing a telephone number of a transmission source and a transmission destination. The telephone number stored in the communication data 60 is different from the communication data used by the mobile device and the base station 2 for data transmission. Also,
For example, in the case of a mail sent from a personal computer via the Internet, the communication data 60 stores the telephone number of the dummy information.

Since mobile unit A or mobile unit B is the portable telephone shown in FIG.
It has the function of rejecting the reception of short messages sent from. FIG. 4 shows a flowchart of registration of a rejected address in these mobile devices. Hereinafter, the registration procedure of the rejected address will be described with reference to FIG.

When registering a rejected address, the user selects a message received from a partner who does not want to receive it (102). The selection of the e-mail for registering the rejected address is performed by displaying the history of the received e-mail list on the display unit 22 (FIG. 1).
Reference) and you can choose from them,
The user can also directly select the displayed mail. When the mail is selected, the data 50 (FIG. 3)
E-mail address is automatically searched from among the E-mail addresses (see Reference) (104). At this time, the communication data 60 is searched first, and if the dummy information of the telephone number is included in the data, it is known that the short message is also transmitted. A certain e-mail
You may search for an address.

If the address is found as a result of the search for the E-mail address, the address is adjusted to a predetermined address format and registered as a rejected address (106). By this registration process, even if the first mail received is a mischief mail, a rejected address can be registered without having to check the address or telephone number each time. In addition, if the mail address is known from the beginning, it is of course possible to register the rejected address directly. If the e-mail address is not included in the data 50 of the e-mail to be rejected, the telephone number of the sender is registered instead of the rejected address. Therefore, it is possible to reject an e-mail sent from a registered telephone number. In other words, the registration of the rejection address is preferentially performed, and the phone number of the transmission source is stored in the unlikely event that reading is impossible, so that the next time it can be immediately identified as a mischief mail.

Further, in addition to registering a rejected address from the offensive mails, a specific sentence, character, symbol, etc. generally used in the offensive mails is stored in the RA in the mobile communication terminal.
It can also be stored in M16, and if it is additionally registered as a fixed sentence at the time of transmission of a text message later, registration of a rejected address can be automatically processed, so that it is very convenient to use.

FIG. 5 shows a flowchart when a short message is received by mobile unit A or mobile unit B. Upon receiving the short message, these mobile devices determine whether to reject the specific address (202). That is, when the rejected address shown in FIG. 4 is registered, the received message E-m
E-mai with an email address registered as rejected
It is determined whether the address is 1 (204).

Then, this message indicates that E-
If the message is sent from the mail address, the reception of the message is rejected and the process is terminated (206). In addition, there is no registration to reject a specific address or (2
02), if the address is not an address to be rejected (20)
4), shift to short message reception processing (21)
0). In this manner, if a mail address for which reception of an electronic mail is to be refused is registered in advance, reception of an electronic mail transmitted from this address can be refused.

[0024]

As described above, according to the mobile communication terminal having the function of registering a rejected address from the text mail of the present invention, the address of the party to whom the unpleasant e-mail is sent can be selected by simply selecting the mail. Since it can be registered as a rejected address, there is no need to input the address of the person sending the unpleasant mail while feeling unpleasant. This allows
The user can prevent frequent malicious e-mails from the same e-mail address, and can select only necessary information for himself.
