[Technical field to which the invention belongs]

The present invention relates to a mobile phone and a communication terminal having a function of automatically deleting an e-mail (junk mail) unnecessary for the user.

【0002】

[Conventional technology]

Conventionally, there is a technique for automatically deleting unsolicited e-mail in a communication terminal device such as a mobile phone. For example, when a large number of e-mails are received from the same source, or when an e-mail of unknown source is received, the e-mail has a function to automatically dispose of the above e-mails. Disposal methods and the like are known (see, for example, Japanese Patent Application Laid-Open No. 2000-163341).

【0003】

In addition, a mobile body that is prevented from receiving unsolicited emails by providing a rejection address for rejecting the reception of unsolicited emails and rejecting the reception of e-mails sent from the senders registered in this rejected address. Communication terminals are known (see, for example, Japanese Patent Application Laid-Open No. 11-252252). This gazette also shows a terminal that memorizes specific characters and symbols that are generally included in unpleasant character mail and automatically registers the sender in the rejected address based on the memorized characters. Has been done.

【0004】

Further, there is known a communication system in which when a user receives a message that is not needed, the unnecessary message is discarded without being stored in the mailbox (see, for example, Japanese Patent Application Laid-Open No. 4-54756).

【0005】

[Problems to be Solved by the Invention]

However, in the mail disposal method and communication terminal shown in JP-A-2000-163341 and JP-A-11-252252, if unsolicited e-mail is repeatedly sent from the same source, the received e-mail is disposed of. You can do this or reject the reception, but if the sender's name or address is changed, or if you receive the junk mail for the first time, you cannot delete the junk mail. Further, in the communication terminals and communication systems shown in JP-A-11-252252 and JP-A-4-54756, the specific characters and unnecessary messages are accidentally included in the necessary received mails. If this is the case, there is a risk that the above-mentioned necessary received mail will be accidentally discarded.

【0006】

The present invention has been made to solve the above-mentioned problems, and it also finds an unsolicited e-mail sent by changing the source address, deletes the junk e-mail, and receives the necessary e-mail at that time. An object of the present invention is to provide a mobile phone and a communication terminal having an automatic junk e-mail deletion function that prevents accidental deletion of e-mails.

【0007】

[Means for solving problems]

In order to achieve the above object, the invention of claim 1 is a receiving means for receiving an e-mail, a storage means for storing an e-mail (received mail) received by the receiving means, and a receiving means stored in the storage means. In a mobile phone equipped with a display means for displaying an email, a keyword / quantity setting means for setting a keyword for automatic deletion of an email, which is assumed to be included in the body of the received email, and a keyword / quantity setting means for setting the number thereof, and a storage means. Search means for searching whether the number of keywords set by the keyword / number setting means is included in the body of each received mail stored in, and the result of the search by the search means, the number of keywords is included in the set number or more. It is a mobile phone having an automatic junk e-mail deletion function, which is provided with an e-mail automatic deletion means for automatically deleting the received e-mail from the storage means when the e-mail is received.

【0008】

In this configuration, the number of keywords contained in the body of each received mail is searched, and as a result, when the number of keywords exceeding the set number is included in the body, the received mail is a junk mail. It is judged that it is automatically deleted from the storage means. In this way, by searching the body of the received e-mail, it is determined whether or not the received e-mail is junk e-mail. Therefore, when the sender of the junk e-mail changes the address, a new source is used. Even if an unsolicited email is sent from an address, the unsolicited email can be found and deleted. In setting the above keywords and their number, for example, using the operation keys for inputting numbers and characters provided on the mobile phone, the user can arbitrarily set the keywords and their numbers that are likely to be included in the junk mail. do it. In addition, when the received mail contains keywords less than or equal to the set number, the received mail is not deleted. Therefore, if the user sets the above number appropriately, there is less risk of accidentally deleting the necessary received mail. can do. A plurality of keywords can be set, and at that time, the above number can be set for each keyword. At this time, if a plurality of set keywords are searched by the and condition, the accuracy of the above determination can be improved, and the unsolicited e-mail can be deleted more reliably.

【0009】

The invention of claim 2 is a receiving means for receiving an e-mail, a storage means for storing the e-mail (received mail) received by the receiving means, and a display for displaying the received mail stored in the storage means. In a communication terminal equipped with the means, the keyword / number setting means for setting the keyword for automatic deletion of the mail, which is assumed to be included in the body of the received mail, and the number thereof, and the storage means are stored. When the search means for searching whether the number of keywords set by the keyword / number setting means is included in the body of each received mail and the result of the search by the search means include more than the set number of keywords. , A communication terminal having an automatic junk e-mail deletion function, which is provided with an e-mail automatic deletion means for automatically deleting the received e-mail from the storage means.

【0010】

In this configuration, the same operation as in claim 1 can be obtained in the communication terminal. In setting the keywords and their numbers, for example, using a keyboard for inputting numbers and characters provided in the communication terminal, the keywords and their numbers that are likely to be included in the junk mail by the user can be arbitrarily selected. It should be set to.

【0011】

The invention of claim 3 is a receiving means for receiving an e-mail, a storage means for storing the e-mail (received mail) received by the receiving means, and a display for displaying the received mail stored in the storage means. In a communication terminal equipped with the means, a keyword for automatic deletion of an email that is expected to be included in the body of the received email and a ratio of the number of the keyword to the total number of texts contained in the body are set. Keyword / ratio setting means for searching, a search means for searching whether the keyword set by the keyword / ratio setting means is included in the body of each received mail stored in the storage means, and a search means. A communication terminal having an automatic junk e-mail deletion function, which is equipped with an e-mail automatic deletion means that automatically deletes the received e-mail from the storage means when the keyword is included in the set ratio or more as a result of the search by. It is a machine.

【0012】

In this configuration, the ratio of the number of keywords to the total number of characters contained in the body of each received mail is searched, and as a result, when keywords exceeding the set ratio are included, the received mail is junk mail. It is determined that this is the case, and it is automatically deleted from the storage means. In this way, it is determined whether or not the received e-mail is junk e-mail by searching the body of the received e-mail, so even if the junk e-mail is sent from a new source address, You can delete junk mail. In addition, since the ratio of the number of keywords to the total number of characters in the body of the received mail is searched, for example, since the body of the required received mail is a long sentence, there are cases where many of the above keywords are included. However, it is possible to reduce the risk of accidentally deleting necessary received mail. The keywords and their ratios can be set in the same manner as in claim 2. In addition, a plurality of keywords can be set, and at that time, a ratio can be set for each keyword. At this time, if a plurality of set keywords are searched by the and condition, the accuracy of the above determination can be improved, and the unsolicited e-mail can be deleted more reliably.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) Hereinafter, a mobile phone according to an embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the configuration of a mobile phone. This mobile phone has a function to automatically detect and delete unsolicited e-mail. The mobile phone 1 includes a transmission / reception circuit (reception means) 2, a reception unit 3, a transmission unit 4, a display unit (display means) 5 including an LCD (Liquid Crystal Display), and an operation unit 6 having various keys. , The CPU 7 that controls the mobile phone 1 and the memory (storage means) 8 that stores the control program 8a of the CPU 7 are provided. In memory 8, in addition to the control program 8a, a telephone directory / address book 8b for referring to the telephone number and e-mail address of the other party during communication, an outgoing e-mail 8c sent, an received e-mail 8d received, and an unsolicited e-mail Keywords set by the user for deletion and their number 8e, etc. are stored.

【0014】

The telephone directory / address book 8b, the outgoing mail 8c, the received mail 8d, and the like stored in the memory 8 are displayed on the display unit 5. These displays are made by operating the CPU 7 according to the control program 8a based on an operation command input by the user from the operation unit 6. For example, when a user inputs a received mail viewing command from the operation unit 6, the CPU 7 reads the received mail 8d stored in the memory 8 and displays it on the display unit 5.

【0015】

Furthermore, the mobile phone 1 has a function of searching the body of the received mail by operating according to the control program 8a, finding the unsolicited mail based on the search result, and automatically deleting it from the memory 8. .. In order to automatically delete unsolicited e-mail, first, let the user set the keywords that are likely to be included in the unsolicited e-mail and the number of them. At this time, the set keywords and their numbers are stored in the memory 8 as keywords / numbers 8e. Then, when the e-mail is received, after storing the received e-mail in the memory 8, it is searched whether the above keywords are included in the body of each received e-mail more than the set number, and the received e-mail is a junk e-mail. Judge whether or not. When the received mail contains more than the set number of keywords, it is determined that the received mail is a junk mail, and the received mail is immediately deleted from the memory 8. At this time, the CPU 7 and the control program 8a constitute a keyword / number setting means, a search means, and an automatic mail deletion means.

【0016】

Figures 2 (a) and 2 (b) show the processing procedure of the keyword / number setting operation and the automatic deletion operation of unsolicited mail executed by the CPU 7 according to the control program 8a. First, in the communication standby state of the mobile phone 1, the standby display screen is displayed on the display unit 5 (# 1). When the user inputs a command to start setting the keyword / number (YES in # 2), the user is made to set the keyword for automatic deletion of mail and the number thereof, and stores them in the memory 8 (# 3). When the above settings are completed (YES in # 4), the standby screen is displayed on the display unit 5 again (# 5). If NO in # 2, it returns to # 1, and if it is NO in # 4, it returns to # 3. This completes the keyword / number setting.

【0017】

The automatic deletion of unsolicited e-mail is done by the following processing procedure. When the standby display screen is displayed on the display unit 5 in the communication standby state of the mobile phone 1 (# 6), when an e-mail is received (YES in # 7), the received mail is stored in the memory 8 (# 8). ). Then, it automatically checks whether the set keyword is included in the body of the received mail more than the set number (# 9). As a result, if the set keyword is included in the text more than the set number (YES in # 10), the received mail is deleted from the memory 8 (# 11). After that, when a mail viewing command is input from the user (# 12), the received mail stored in the memory 8 is displayed on the display unit 5 (# 13). If no e-mail is received in # 7 (NO in # 7), or if the e-mail viewing command is not input in # 12 (NO in # 12), the screen returns to # 6 and the standby screen is displayed. Also, if the number of keywords is not included in the text in # 10 (NO in # 10), the received mail is moved to # 12 without being deleted from the memory.

【0018】

FIG. 3 shows the mobile phone 1 in which the keyword / number setting screen is displayed on the display unit 5 in # 3. The user can set the keywords and the number thereof by operating the operation keys of the operation unit 6 while looking at the above setting screen shown on the display unit 5. Here, the number "2" is set for the keyword "Mel friend", and the number "3" is set for the keyword "lover". In this way, the user can arbitrarily set words that are likely to be included in the junk e-mail as keywords. In addition, a plurality of keywords can be set, and at that time, the number of keywords can be arbitrarily set for each keyword.

【0019】

In this way, according to the mobile phone 1, when an e-mail is received, it is stored in the memory 8 and then promptly determined whether or not the received e-mail is a junk e-mail. I try to delete it. Therefore, the user does not feel uncomfortable due to the unsolicited mail. In addition, it is possible to save the trouble of deleting unsolicited e-mails one by one. Furthermore, when determining whether the received e-mail is junk e-mail, the body of the received e-mail is searched, so if the sender of the junk e-mail changes the address, the new source address will be used. Even if an unsolicited email is sent, the unsolicited email can be found and deleted.

【0020】

In addition, when the body of each received mail contains more than the set number of keywords, the mobile phone 1 determines that the received mail is unsolicited mail and automatically deletes it from the memory 8. There is. Therefore, when the number of keywords included in the text is less than or equal to the set number, the received mail is not deleted. Therefore, if the user sets the above number appropriately, there is a risk of accidentally deleting the necessary received mail. Can be reduced.

【0021】

The present invention can be modified in various ways without being limited to the configuration of the above embodiment. For example, the communication device equipped with the above-mentioned automatic junk e-mail deletion function is not limited to a mobile phone, for example, the Internet and the like. It may be a communication terminal capable of receiving e-mail represented by a personal computer or the like connected to the network of. In addition, in determining whether the received e-mail is unsolicited e-mail, the ratio of the number of the keywords to the total number of characters contained in the body is not limited to the method of searching the number of keywords contained in the body. A search method may be used. In this case, the user may set the ratio of the number of the keywords to the total number of characters instead of the number of the keywords set in # 3.

【0022】

Further, when a plurality of keywords and their numbers are set as shown in FIG. 3, the search may be performed for these plurality of keywords by an and condition. In this way, the accuracy of determining whether or not the received e-mail is junk e-mail can be improved, and the junk e-mail can be deleted more reliably.

【0023】

[Effect of the invention]

As described above, according to the invention of claim 1, it is determined whether or not the received e-mail is an unsolicited e-mail by searching the body of the e-mail received by the mobile phone. Therefore, even if the junk e-mail is sent from a new source, the junk e-mail can be deleted. The process from searching for junk e-mail to deleting it is done automatically every time an e-mail is received, so that the user does not feel uncomfortable with the junk e-mail. In addition, the number of keywords included in the text is searched, and when the number of searches is greater than or equal to the set number, the received mail is deleted, so there is less risk of accidentally deleting the necessary received mail. can do.

【0024】

According to the invention of claim 2, the same effect as that of claim 1 can be obtained in the communication terminal.

【0025】

According to the invention of claim 3, since it is determined whether or not the received e-mail is a junk e-mail by searching the body of the e-mail received by the communication terminal, the junk e-mail is sent from a new source. Even if it is sent, the junk mail can be deleted. The process from searching for junk e-mail to deleting it is done automatically every time an e-mail is received, so that the user does not feel uncomfortable with the junk e-mail. In addition, it is possible to save the trouble of deleting unsolicited e-mails one by one. In addition, the ratio of the number of keywords to the total number of characters in the body of the received mail is searched, and when the searched ratio is equal to or more than the set ratio, the received mail is deleted. Therefore, for example, the required received mail is deleted. Since the text of is a long sentence, it is possible to reduce the risk of accidentally deleting the received mail even when a large number of keywords are included in the text.
