Although voice communication is explained as an example of communications in calling or incoming mode, data communications for packet or image data can also be performed in such a mode. In addition, in call waiting mode or character communications mode, the control section 10 displays the character data processed by the data processing section 23 on the display section 30.
  • The operation of automatically deleting any logged calls and messages, which are preferred by a user to not be recorded in a mobile phone, for security maintenance and privacy protection, will be explained in detail. The user of the mobile phone can store telephone numbers, which are preferred to not be recorded in the mobile phone, in the log deleting management database. When a voice call is made, the control section 10 determines whether the telephone number received with the voice call is present in the log deleting management database. If the received telephone number is present in the log deleting management database, the control section 10 will not record the number in the recently received number list. The non-stored telephone number can be stored in the secret received number list, depending on the method of recording the number.
  • When the user of the mobile phone tries to make a phone call by inputting a telephone number, the control section 10 determines whether the telephone number is present in the log deleting management database. If the number is present, the control section 10 will not record the number in the recently dialed number list. The user can make a phone call to the number which was not stored while concealing or displaying the number and the caller to the recipient of the call, depending on the method of dialing the same number.
  • When a message is received, the control section 10 determines whether the telephone number received with the message is present in the log deleting management database. If the telephone number is present in the log deleting management database, the control section 10 will not store the message in the received message list. The non-stored message can be stored in the secret received message list, upon the user's choice.
  • When the user of the mobile phone sends a message, the control section 10 determines whether the telephone number of the message recipient is present in the log deleting management database. If the telephone number is present in the log deleting management database, the control section 10 will not store the message in the sent message list. The non-stored message can be stored in the secret sent message list, depending upon the user's choice.
  • FIG. 2 is a flowchart showing an example of steps for recording and managing telephone numbers in a log deleting management database in a mobile phone in accordance with an embodiment of the present invention.

If the user selects the log deleting management database using the keypad 27 while the menu is displayed, the control section 10 will detects this selection in step 101 and displays a message to the user requesting a password input. If the user inputs a password in step 102, the control section 10 determines whether the input password is correct. If the password is correct, the control section 10 detects it in step 103 and displays types of the log deleting management database on the display section 30.
  • If the password input by the user is not correct, the control section 10 detects it in step 103 and proceeds to step 104 for displaying a message “no telephone number recorded” on the display section 30. A person other than the user can input a password to see the log deleting management database of the mobile phone. If the message “no telephone number recorded” is displayed, the unauthorized user believes that there is no recorded telephone number, and will not try to input another password. At least one message can be stored in a memory 29 and displayed in step 104. The user can select the one message to be displayed.
  • If the user selects an option to record a telephone number while the types of the log deleting management database are displayed, the control section 10 detects it in step 106 and proceeds to step 107. In step 107, the user of the mobile phone can input a new telephone number which the user prefers not be recorded in a general call log or a message log, a method of dialing the number and a method of recording the number. The user can input a new telephone number directly using the keypad or using a phonebook. The dialing method refers to a determination of whether a telephone number input in step 107 and the caller should be revealed to the recipient when the number is dialed. The recording method refers to a determination of whether a telephone number input in step 107, if received, should be recorded in the secret received number list. If an “OK” key is input when a telephone number input in step 107 is completed, the control section 10 detects it in step 108 and stores the input new telephone number and the method of dialing and recording the number in the log deleting management database. If the “OK” key is not input in step 108, the method returns to step 107.
  • If the user selects an option to not record a telephone number in step 106 or not to access the log deleting management database in step 101, the control section 10 detects it and proceeds to step 120 where the user decides on the next required function.
  • If the user selects a telephone number list while the types of log deleting management database are displayed, the control section 10 detects it in step 105 and displays the telephone numbers stored in the log deleting management database on the display section 30. If the user selects a new record while the telephone numbers stored in the log deleting management database are displayed, the control section 10 detects it in step 109 and proceeds to step 110. In step 110, the user can input a new telephone number, which the user prefers not be recorded in the general call log or the message log, a method of dialing the number or a method of recording the number. The user can input a new telephone number directly or using the phonebook. The dialing method refers to a determination of whether a telephone number input in step 107 and the caller's name should be revealed to the recipient, when the number is dialed. The recording method refers to a determination of whether a telephone number input in step 110, if received, should be recorded in the secret received number list. If the “OK” key is input when a telephone number input in step 110 is completed, the control section 10 detects it in step 111 and stores the newly input telephone number and the method of dialing and recording the number in the log deleting management database.
  • If the user selects a deletion while the telephone numbers stored in the log deleting management database are displayed, the control section 10 detects it in step 112 and proceeds to step 113. If the user presses the “OK” key in step 113 after selecting a telephone number to delete, the control section 10 detects it in step 114 and deletes the selected telephone number from the log deleting management database.
  • If the user selects a correction while the telephone numbers stored in the log deleting management database are displayed, the control section 10 detects it in step 115 and proceeds to step 116. If the user presses the “OK” key in step 113 after selecting a telephone number to be corrected, the control section 10 detects it in step 117 and stores a corrected telephone number in the log deleting management database.
  • FIG. 3 is a flowchart showing an example of steps for automatically deleting a received telephone number corresponding to a log deleting management database in a mobile phone in accordance with an embodiment of the present invention.
  • Hereinafter, the embodiment of the present invention shown in FIG. 3 will be described in more detail, with reference to FIGS. 1 and 2.
  • In step 200, if a voice call is received while the mobile telephone is in a call waiting mode, the control section 10 will detects it in 201 and proceeds to step 202 for reading the telephone numbers stored in a phonebook of the mobile phone. In step 202, the control section 10 determines whether the received telephone number is present in the phonebook and provides a number identification service via the display section 30. If the number is present in the phonebook, the display section 30 displays the number and any pertinent information stored in the phonebook that is associated with the stored telephone number, namely, the caller's name. In step 203, the control section 10 reads the telephone numbers stored in the log deleting management database. The control section 10 then determines whether the received telephone number is stored in the log deleting management database. If the received number is not stored in the log deleting management database the control section 10 detects it in step 204 and proceeds to step 205. In step 205, the control section 10 stores the received number in the recently received number list and performs a communication or another required function in step 208.
  • If the received number is present in the log deleting management database in step 203, the control section 10 detects it in step 204 and does not record the received number in the recently received number list. In step 204, the control section 10 determines a method of recording the received number. If the recording method is to record the received number in the secret received number list, the control section 10 detects it in step 206 proceeds to step 207. In step 207, the control section 10 records the received number in the secret received number list and performs a communication or another required function in step 208. On the other hand, if the method of recording the received number is not to record the received number in the secret received number list, the control section 10 detects it in step 206 and performs a communication or any required function, without recording the received number in the secret received number list.
  • According to the preferred embodiment of the present invention, when a telephone number included in the telephone number list of the log deleting management is received, it is automatically deleted and is not recorded in the general call log or the recently received number list. Alternatively, a message “no caller information” can be displayed for that received number. In other words, when a telephone number present in the log deleting management is received, “no caller information” is displayed in the general call log and the recently received number list. If the user inputs the OK key to identify the telephone number corresponding to the message “no caller information” or the send key to initiate a call, the message “no caller information” will still be displayed, with no information being provided about the received telephone number.
  • FIG. 4 is a flowchart showing an example of steps for reading the list of secret received telephone numbers of FIG. 3 in accordance with an embodiment of the present invention.
  • Hereinafter, the embodiment of the present invention shown in FIG. 4 will be described in more detail, with reference to FIG. 1.
  • If the user of the mobile phone presses a menu key on the keypad 27, the control section 10 detects it and controls the display section 30 to display the menu in step 250. If the user selects the log deleting management database using the keypad 27 while the menu is displayed, the control section 10 detects it in step 251 and displays the types of the log deleting management database on the display section 30. If the user selects the secret received number list while the types of the log deleting management database are displayed, the control section 10 detects it in step 252 and displays a message requesting a password input. If the user inputs a password in step 253, the control section 10 determines whether the input password is correct. If the password is correct, the control section 10 detects it in step 254 and displays the telephone numbers stored in the secret received number list on the display section 30 in step 255.
  • If the user does not access the log deleting management database in step 251 or does not access the secret received number list in step 252, the method proceeds to step 260 where the user decides upon the next required function. The next required function is beyond the scope of the present invention.
  • If the password input by the user is not correct, the control section 10 detects it in step 254 and proceeds to step 256 for displaying a message “no telephone number recorded” on the display section 30. A person other than the user can input a password to see the log deleting management database of the mobile phone. If the message “no telephone number recorded” is displayed, the unauthorized user believes that no telephone number is recorded, and will not try to input another password. At least one message can be stored in the memory 29 in order to be displayed in step 256. The user can select one message to be displayed.
  • FIG. 5 is a flowchart showing an example of steps for automatically deleting a dialed telephone number corresponding to a log deleting management database in a mobile phone in accordance with an embodiment of the present invention.
  • Hereinafter, the embodiment of the present invention shown in FIG. 5 will be described in more detail, with reference to FIGS. 1 and 2.
  • If the user inputs a telephone number and presses the “send” key at step 300 to make a phone call while the mobile telephone is in a call waiting mode, the control section 10 detects it in step 301 and proceeds to step 302. In step 302, the control section 10 searches the phonebook to determine whether the telephone number is present, and displays the number on the display section 30. If the telephone number is present in the phonebook, information stored in the phonebook regarding the number, i.e., the recipient, will be displayed on the display section 30. In step 303, the control section 10 reads the telephone numbers stored in the log deleting management database and determines whether the input number is present in the log deleting management database. If the input number is not present, the control section 10 detects the absence of the number in step 304 and proceeds to step 305. In step 305, the control section 10 stores the input number in the recently dialed number list and performs a dialing function.
  • If the input number is present in the log deleting management database in step 303, the control section 10 detects that the input number is stored in the management database in step 304 and will not record the number in the recently dialed number list. The control section then proceeds to step 306 for determining a method of dialing the input number. If it is determined in step 306 that the input number should be dialed without revealing the number and the caller to the recipient, the control section 10 proceeds to step 307 for performing a dialing function, while concealing the number and the caller to the recipient. On the other hand, if it is determined in step 306 that the input number should be dialed with the number and the caller name displayed, the control section 10 performs a dialing function in step 308, while displaying the number and the caller.
  • According to this embodiment of the present invention, when the user dials a telephone number included in the telephone number list of the log deleting management, the number is automatically deleted and is not recorded in the general call log or the recently dialed number list. Alternatively, a message “no caller information” can be displayed for that dialed number. In other words, when a telephone number present in the log deleting management is dialed, “no caller information” is displayed in the general call log and the recently dialed number list. If the user inputs the OK key to identify the telephone number corresponding to the message “no caller information” or the send key to initiate a phone call, the message “no caller information” will still be displayed, with no information being provided about the dialed telephone number.
  • FIG. 6 is a flowchart showing an example of steps for automatically deleting a message received from a telephone number corresponding to a log deleting management database in a mobile phone in accordance with an embodiment of the present invention.
  • Hereinafter, the embodiment of the present invention shown in FIG. 6 will be described in more detail, with reference to FIGS. 1 and 2.
  • If a message is received in step 400, the control section 10 proceeds to step 401 for parsing the message and the telephone number received together. In step 402, the control section 10 searches the phonebook of the mobile phone to determine whether the telephone number of the received message is stored in the phonebook, and displays both the message and the telephone number on display section 30. If the telephone number is present in the phonebook, the control section 10 displays the received message and telephone number and the information stored in the phonebook regarding the telephone number, i.e., the caller on the display section 30. In step 403, the control section 10 reads the telephone numbers stored in the log deleting management database and determines whether the telephone number of the received message is stored in the log deleting management database. If the number is not stored, the control section 10 detects that the number is not stored in step 404 and proceeds to step 407. In step 407, the control section 10 stores the received message in the received message list, and then performs another next required function in step 408.
  • If the telephone number received with the message is stored in the log deleting management database in step 403, the control section 10 detects the stored telephone number in step 404 and does not record the message in the received message list. If the user chooses to store the message in the secret received message list which can be accessed only by the user, the control section 10 detects it in step 405 and proceeds to step 406. In step 406, the control section 10 stores the message in the secret received message list, and performs any next required function in step 408.
  • According to this embodiment of the present invention, when a message is received from a telephone number included in the telephone number list of the log deleting management, the message is automatically deleted and is not stored in the general received message list. Alternatively, a message “no information” can be displayed for that received message. In other words, when a message is received from a telephone number present in the log deleting management, “no information” is displayed in the general received message list. If the user inputs the OK key to identify the message or the send key to initiate a phone call, “no information” will still be displayed in the general received message list, with no information being provided about the received message.
  • FIG. 7 is a flowchart showing an example of steps for automatically deleting a message sent to a telephone number corresponding to a log deleting management database in a mobile phone in accordance with an embodiment of the present invention.
  • Hereinafter, the embodiment of the present invention shown in FIG. 7 will be described in further detail, with reference to FIGS. 1 and 2.
  • The control section 10 detects that the user inputs a message and a telephone number to send and presses the “OK” key in step 500, and in step 501 and proceeds to step 502. In step 502, the control section 10 reads the telephone numbers stored in the log deleting management database, and determines whether the telephone number dialed to send the message is present in the log deleting management database. The control section 10 detects that the number is not present in step 503 and proceeds to step 506. In step 506, the control section 10 stores the message in the sent message list, and performs a message sending function.
  • The control section 10 detects that the telephone number dialed to send the message is stored in the log deleting management database in step 503 and does not record the message in the sent message list. If the user chooses to store the message in the secret sent message list, which can be accessed only by the user, the control section 10 detects it in step 504 and proceeds to step 505. In step 505, the control section 10 stores the message in the secret sent message list, and performs any next required function in step 507.
  • According to this embodiment of the present invention, when a message is sent to a telephone number included in the telephone number list of the log deleting management, the message is automatically deleted and is not stored in the general sent message list. Alternatively, a message “no information” can be displayed for that sent message. In other words, when a message is sent to a telephone number present in the log deleting management, “no information” is displayed in the general sent message list. If the user inputs the OK key to identify the sent message or the send key to initiate a phone call, “no information” will still be displayed in the general sent message list, with no information being provided about the sent message.
  • Also, when a voice message is received from a telephone number included in the telephone number list of the log deleting management, the user can hear the voice message in a secret voice mailbox. The voice message is not recorded in a general voice mailbox. For the voice message, a message “no information” can be displayed in the general voice mailbox. Even if the OK key is input, the received voice message cannot be heard in the general voice mailbox.
  • In addition, it is possible to set a special incoming icon or bell sound for the telephone numbers stored in the log deleting management. Alternatively, a distinguishing character picture or sound, wherein the bell sound can comprise a ringing tone, can be set for those telephone numbers.
  • The present invention having the construction and operations as explained above produces advantageous effects.
  • That is, an embodiment of the present invention for automatically deleting logged calls and messages, which a user prefers not to record in a mobile phone, enables the user of the mobile phone to ensure security maintenance and privacy protection, without having the inconvenience of manually deleting telephone numbers or messages stored in a daily call log or a message log of the mobile phone.
  • Although embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope of the invention as disclosed in the accompanying claims.
