Abstract

<P>PROBLEM TO BE SOLVED: To improve the convenience of a lock function by allowing the owner of a communication terminal to easily guess who a caller is even in the case of setting a lock function that does not display the caller during an incoming call in a communication terminal such as a cellular phone. <P>SOLUTION: The communication terminal stores display information 13 for a locked time generated from a character string included in a telephone book data apart from information such as a name displayed during an incoming call with a lock released, and displays the registered display information 13 for a locked time without displaying the name of a caller when receiving an incoming call during lock setting. Consequently, although a third person can not identify the caller, the owner of the communication terminal can identify the caller. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an information display technique at the time of an incoming call in a communication terminal device such as a mobile phone.

When a communication terminal device such as a conventional general mobile phone receives an incoming call, it searches the telephone directory stored in the mobile phone based on the caller's phone number. As in the example, the name, telephone number, etc. of the caller are displayed.
Since this phone book stores personal information such as name and phone number, it should be protected from being seen by a third party. For this reason, many mobile phones have a lock function to prevent browsing and editing of the phone book and other data called PIM (Personal Information Manager) lock, secret mode, memory use prohibition, etc.
To unlock, it is necessary to enter a password that only the owner knows. For example, even if the mobile phone is lost or stolen, only the third party such as the person who found the phone book or the thief can find the phone book. I can't.
Further, since the personal information is leaked when the telephone number and the name are displayed together when the incoming call is received, only the caller's telephone number is displayed in the locked state as in the example of FIG. It is common. That is, when the lock setting (display restriction setting) is performed, the display of the character string indicating the name of the communication partner is restricted when an incoming call is received.
For example, when the PIM lock is set, there is a mobile phone in which only the telephone number is displayed without displaying the name of the other party even if the other party registered in the phone book receives a call.

FIG. 38 shows a configuration diagram of a communication terminal device 2 such as a conventional mobile phone. Hereinafter, it is also simply referred to as a communication terminal 2.
The communication terminal 2 includes a display unit 21 for displaying information to the user, an operation unit 22 for receiving input from the user, a communication unit 23 for performing communication such as telephone and mail, and incoming calls such as telephone and mail. Incoming call screen generation unit 24 for generating a screen and sound to be displayed at the time, a lock management unit 25 for managing whether or not it is in a locked state, and a user interface for a user to register / edit phone book data Phone book data editing control unit 26 and phone book data management unit 27 for managing phone book data.

The user operates the operation unit 22 while viewing the display unit 21, inputs / edits the phone book data through the phone book data editing control unit 26, and stores the phone book data in the phone book data management unit 27.
FIG. 33 shows an example of a conventional telephone directory data input / edit screen.
E21 shows a screen before input, and E22 shows a screen after input.
The user uses the operation unit 22 to input each item of the phone book such as name, and when the user finally performs a save operation using the save button, it is stored in the phone book (E23).
FIG. 34 shows an example of phone book data managed by the phone book data management unit 27.

Further, the user operates the operation unit 22 to set or release the lock.
At this time, the lock state is held in the lock management unit 25.
FIG. 35 shows an example of a screen for setting (ON) or releasing (OFF) the PIM lock function.
When the user selects the PIM lock on the screen of E31, a screen for inputting a personal identification number is displayed (E32).
Here, only when the correct password set in advance in the communication terminal 2 is input, the PIM lock function change screen shown in E33 can be changed to change the setting (ON) or release (OFF) state. it can.

FIG. 36 is a flowchart when a conventional communication terminal receives an incoming call.
Hereinafter, the operation of the conventional communication terminal when receiving an incoming call will be described with reference to FIGS. 38 and 36. FIG.
When the communication unit 23 of the communication terminal 2 receives an incoming call (S101 in FIG. 36), the communication unit 23 acquires the caller number if the caller number is notified from the caller, and the incoming call screen generation unit 24 receives the incoming call screen. Is displayed.
The incoming call screen generation unit 24 checks whether or not the caller number has been acquired (S102).
When the caller ID is not notified, the incoming call screen generation unit 24 generates an incoming call screen indicating that the incoming call is received and displays it on the display unit 21 (S111).
FIG. 37 shows an example of an incoming call screen indicating only that an incoming call has been received.

On the other hand, when the caller number is notified, the incoming call screen generation unit 24 searches the phone book data in which the telephone number that matches the caller number is registered. Specifically, the phone book data management unit 27 is instructed to search, and the phone book data management unit 27 is made to search.
The phone book data management unit 27 searches the phone number information of the phone book data using the caller number as a key, and returns the result to the incoming call screen generation unit 24 (S103).
FIG. 34 shows an example of phone book data managed by the phone book data management unit.
For example, when the caller number is “09055555111”, the data No. 1 is the same as the telephone number information in FIG. Returns 1 data.
The incoming call screen generation unit 24 checks whether or not phone book data matching the caller number has been found (S104).
When the phone book data matching the caller number is not found, the incoming call screen generation unit 24 generates an incoming call screen for displaying the caller number and displays it on the display unit 21 (S112).
FIG. 32 shows an example of an incoming call screen that displays a caller ID.

When the phone book data matching the caller number is found, the incoming call screen generation unit 24 checks the lock state managed by the lock management unit 25 (S105).
In the unlocked state (No), the incoming call screen generation unit 24 generates an incoming call screen including information such as the name of the phone book data and displays it on the display unit 21 (S114).
FIG. 31 shows an example of an incoming call screen including information such as a name.
In the lock setting state (Yes), the incoming call screen generation unit 24 generates an incoming call screen (FIG. 32) for displaying the caller ID and displays it on the display unit 21 (S112).

  As described above, in the conventional communication terminal, in the state where the caller number is notified and the lock function is set, even if the call is received from the caller registered in the phone book, the phone number Only is displayed (FIG. 32).

When an incoming call is received with the lock function of the conventional mobile phone set, no information other than the phone number is displayed, so even the owner of the phone is inconvenient because it cannot identify who the caller is. There are challenges.
Further, since the caller's phone number is displayed, there is a problem that the phone number information related to the owner of the mobile phone is leaked to a third party.
Furthermore, if there is a user who does not set the lock function due to the inconvenience described above, and the mobile phone without the lock function is lost or stolen, personal information stored in the phone book leaks. There was also a problem of ending up.

The main object of the present invention is to solve the above-described problems. When a lock function of a communication terminal such as a mobile phone is set, that is, the display of a character string indicating the name of a communication partner is limited when an incoming call is received. Even when the display restriction is set, the main purpose is to make it easier for the owner of the communication terminal to guess who the caller is when receiving a call and to improve the convenience of the lock function.
In addition, the main purpose is not to display the caller's telephone number when an incoming call is received and to prevent the telephone number from being leaked to a third party.
Furthermore, the main purpose of these advantages is to prevent the leakage of personal information when the user is lost or stolen by making it easier for the user to use the lock function.

The communication terminal device according to the present invention is
When the display restriction setting is not performed, the display unit displays a communication partner name character string indicating the name of the communication partner, and
A communication terminal device that restricts display of a communication partner name character string by the display unit when display restriction setting is performed,
A restriction setting time symbol information storage unit that stores information representing the communication partner without indicating the name of the communication partner as restriction setting time symbol information;
Incoming information that restricts the display of the communication partner name character string by the display unit and outputs the restriction setting time symbol information stored in the restriction setting time symbol information storage unit when there is an incoming call at the time of display restriction setting. And a control unit.

According to the present invention, when there is an incoming call when the display restriction is set, the display of the communication partner name character string is restricted and the restriction setting time representation information representing the communication partner is output without showing the name of the communication partner. Therefore, the owner of the communication terminal device can identify the communication partner, but the third party cannot identify the communication partner.
And since the convenience at the time of display restriction setting can be improved in this way, the use of the display restriction setting is promoted, and even if there is an incoming call when the communication terminal device is lost or stolen, the third party's name of the communication partner It can be avoided that personal information leaks.

Embodiment 1 FIG.
FIG. 1 shows an example of the contents of a telephone directory stored in a communication terminal device such as a mobile phone or a pager in this embodiment, and an incoming call screen in the lock setting state.
In the present embodiment, in the lock setting state, that is, when the display restriction setting that restricts the display of the character string (communication partner name character string) indicating the name of the communication partner at the time of an incoming call is performed, The display information 13 for lock time (representation information at the time of restriction setting) representing the communication partner without displaying the name is displayed. The lock display information 13 is also referred to as lock display information 13.
In other words, separately from the information such as the name displayed when an incoming call is received in the unlocked state, the display information 13 for locked time is registered in the contents 11 of the phone book. The display information for lock 13 is displayed on the screen.

When the owner (user) of the communication terminal 2 locks the information representing the communication partner without indicating the name of the communication partner, in other words, a character string that cannot be identified by a third party and can only be identified by the owner. Registered in the display information 13 for use.
For example, as shown in FIG. 1, a combination of the first letter of the subject's reading and the first letter of the group is registered.
Also, as shown in FIG. 30, only the first character of the subject's reading may be registered.
As a result, even if the communication terminal 2 is lost or stolen, the telephone number or name of the caller is not displayed even if an incoming call is received in the lock setting state, and only the lock display information 13 is displayed. Personal information such as phone numbers and names will not be leaked to third parties.

Hereinafter, the configuration and operation of the communication terminal apparatus according to the present embodiment will be described in more detail.

With reference to FIG. 4, the registration processing (representation information storage step at the time of restriction setting) of the display information for lock 13 will be described.
E01 shows a screen before input, and E02 shows a screen after input.
Lock display information 13 is added to the conventional telephone directory data input / edit screen (FIG. 33).
The user uses the operation unit 22 to input each item of the phone book such as name, reading, group, phone number, e-mail address, lock display information 13 and the like, and finally performs a save operation using the save button. The edited phone book data is stored in the phone book data management unit 27.
Here, the user inputs a character string that cannot be identified by a third party and can be identified only by the user (owner of the communication terminal 2) in the display information for lock 13.
The user can generate the display information 13 for locking one or more character strings using a part of the phone book data. For example, a character string in which the first character of the subject's reading or the first character of the group name is combined is registered.
The phone book data management unit 27 stores the lock display information 13 generated in this manner in association with the phone book data.

FIG. 5 shows an example of phone book data managed by the phone book data management unit 27.
In this example, the first character of the reading is input to the display information for locking.
Further, the user operates the operation unit 22 to set or release the lock. At this time, the lock state is held in the lock management unit 25.

Next, the operation when receiving a call will be described with reference to FIGS.
FIG. 3 is a flowchart at the time of incoming call of the communication terminal 2 in this embodiment.

When the communication unit 23 of the communication terminal 2 receives an incoming call (S101 in FIG. 3), the communication unit 23 acquires the caller number if the caller number is notified from the caller, and the incoming call screen generation unit 24 receives the incoming call screen. Is displayed.
The incoming call screen generation unit 24 checks whether or not the caller number has been acquired (S102).
When the caller ID is not notified, the incoming call screen generation unit 24 generates an incoming call screen indicating that the incoming call is received and displays it on the display unit 21 (S111).
FIG. 37 shows an example of an incoming call screen indicating only that an incoming call has been received.

When the caller number is notified, the incoming call screen generation unit 24 searches the phone book data in which the phone number that matches the caller number is registered. Specifically, the phone book data management unit 27 is instructed to search, and the phone book data management unit 27 is made to search.
The phone book data management unit 27 searches the phone number information of the phone book data using the caller number as a key, and returns the result to the incoming call screen generation unit 24 (S103).
FIG. 5 shows an example of phone book data managed by the phone book data management unit.
For example, when the caller number is “09055555111”, the data No. 1 is the same as the telephone number information in FIG. Returns 1 data.

Next, the incoming call screen generation unit 24 checks whether or not phone book data matching the caller number has been found (S104).
When the phone book data matching the caller number is not found, the incoming call screen generation unit 24 generates an incoming call screen for displaying the caller number and displays it on the display unit 21 (S112).
FIG. 32 shows an example of an incoming call screen that displays a caller ID.

On the other hand, when the phone book data matching the caller number is found, the incoming call screen generation unit 24 checks the lock state from the lock management unit 25 (S105).
In the unlocked state (No), the incoming call screen generation unit 24 generates an incoming call screen including information such as the name of the phone book data and displays it on the display unit 21 (S114).
FIG. 31 shows an example of an incoming call screen including information such as a name.

In the lock setting state (Yes), the incoming call screen generation unit 24 checks whether or not the display information for lock 13 in the phone book data is registered (S106).
When the lock display information 13 is not registered, the incoming call screen generation unit 24 generates an incoming call screen (FIG. 32) for displaying the caller number and displays it on the display unit 21 (S112).
When the lock display information 13 is registered, the incoming call screen generation unit 24 generates an incoming call screen that displays only the lock display information 13 and displays it on the display unit 21 (12 in FIG. 1).
3, S105, S106, S111, S112, S113, and S114 correspond to the incoming information control step.

  As described above, in the present embodiment, a display information field for lock is provided in the phone book, and an incoming call in which the caller number is notified is received with the lock function set, and the caller number is set in the phone book. If there is corresponding data, display information for lock is displayed, so even if there is an incoming call when the communication terminal is lost or stolen, personal information such as name and phone number is leaked to a third party At the same time, the phone owner has the advantage of being able to easily identify who is coming from.

In addition, although the screen during the incoming call is mentioned here, the display information for the lock time may be displayed in the lock setting state for the display of the incoming call history and the outgoing call history.
That is, when the display unit 21 is requested to display the incoming call history or outgoing call history when the lock is released (when the display restriction setting is not performed), the display unit 21 displays the name of the communication partner that received the incoming call. Displays the incoming call history character string or the outgoing call history character string that indicates the name of the communication partner that made the call, but displays the incoming call history or outgoing call history when the lock is set (when display restriction is set) Is requested, the incoming call screen generation unit 24 restricts the display of the incoming call history character string or the outgoing call history character string on the display unit 21 and locks it stored in the telephone directory data management unit 27. Display information is displayed as an incoming history or outgoing history.
FIG. 6 shows an example of the screen when the lock display information is displayed on the incoming call history display screen.

Also, here, the case where a character string is designated as the display information at the time of lock is described, but as the display information at the time of lock, a ring tone, display color, backlight color, LED (Light Emitting Diode) color, vibrator vibration pattern, etc. The setting information may be designated.
That is, the phone book data management unit 27 receives a ring tone that is output when an incoming call is received, a display color that is displayed on the display unit 21 when an incoming call is received, a light emission color when a backlight or an indicator arranged in the communication terminal 2 is received, a communication You may make it memorize | store at least any one of the vibration pattern at the time of the incoming call of the vibrator arrange | positioned at the terminal 2 as display information at the time of lock | rock.

  In this example, the lock display information is entered when registering new phone book data. However, a special screen is provided for changing the phone book data or inputting the display information when locked, and other information is displayed when the phone book is locked. May be entered.

  In the above description, the example of generating display information at the time of lock using a character string included in the phone book data has been described, but display at the time of lock using a character string of one or more specific characters not included in the phone book data Information may be generated. For example, special characters such as symbols such as “*” and “#” may be used.

Embodiment 2. FIG.
In the first embodiment, the user generates the lock display information 13. In the second embodiment, the lock display information 13 is automatically set when the phone book data is input / edited. The example which added the means is shown.

FIG. 7 shows a configuration diagram of the communication terminal 2 in this embodiment.
7 are the same as those in FIG. 2 and will not be described.
The lock display information generation unit 28 automatically generates the lock display information 13 with reference to the phone book data.
That is, the display information generation unit 28 at the time of locking uses at least a part of the phone book data stored in the phone book data management unit 27, and does not indicate the name of the phone number holder of the phone book data. A character string of one or more characters representing the holder is generated, and the generated character string is used as lock display information 13 (representation information at the time of restriction setting). The lock time display information generation unit 28 is an example of a restriction setting time symbol information generation unit.
In this embodiment, the phone book data management unit 27 uses the lock-time display information 13 generated by the lock-time display information generation unit 28 as the phone book used to generate the character string of the lock-time display information 13. Store in association with data.

FIG. 8 shows an example of screen transition of the phone book data editing screen in this embodiment.
Next, using FIG. 7 and FIG. 8, the operation when extracting the first character of the reading as the display information at the time of locking will be described.

The user operates the operation unit 22 to open the telephone directory data editing screen (E11 in FIG. 8). Next, the user inputs the kanji and the komi of the name of the telephone number holder (E12 in FIG. 8).
When the reading is input, the phone book data editing control unit 26 automatically requests the lock display information generation unit 28 to generate the lock display information together with the phone book data being edited (E12 to E13 in FIG. 8). Transition to).
The operation flowchart of the lock display information generation unit 28 at this time is shown in FIG. 9, and the operation will be described.

When the lock display information generation unit 28 is requested by the phone book data editing control unit 26 to generate the lock display information together with the phone book data corresponding to the caller number (S300), the lock display information is received from the received phone book data. The value of the phone book data item used to generate display information is acquired (S301). In this example, since “Yomi” item data is used, “Yomi” item data is acquired.
Next, the lock display information is generated using the acquired item data (S302).
In this example, the first character is extracted from the “Yomi” item data acquired in S301. For example, if the reading is “Yamada Taro”, the first character is extracted, and the lock display information “Y” is generated.
Then, the generated display information at the time of lock (“Y” in this example) is returned to the telephone directory data edit control unit 26 (S302).
The phone book data editing control unit 26 inputs the lock display information received from the lock display information generation unit 28 into the lock display information item of the phone book data being edited (E13 in FIG. 8).

Thereafter, when the user operates the operation unit 22 and performs a save operation using the save button, the phone book data edit control unit 26 stores the edited phone book data in the phone book data management unit 27.
The example of the phone book data managed by the phone book data management unit 27 is the same as that in the first embodiment (FIG. 5).

In the present embodiment, the operation when the communication terminal 2 receives an incoming call is the same as that of the first embodiment.
As in the first embodiment, when a caller ID is notified when the lock function is set and there is data corresponding to the caller number in the phone book, the lock display information is displayed. (13 in FIG. 1 or FIG. 30).

  As described above, according to the present embodiment, the lock-time display information generation unit 28 is provided so that the lock-time display information is automatically generated from information such as “Yomi” input by the user. In addition to obtaining the same effect as in the first aspect, it is possible to save the user from having to individually input display information when locked.

  Here, the first character of the reading is extracted and used as the display information at the time of locking. However, this partial character string may be further converted using a conversion table.

  FIG. 10 shows an example of the conversion table. This conversion table indicates that for each of the extracted characters, a line (“A” to “O”) is converted to “1”, K line is converted to “2”, Y line is converted to “8”, and the like. This conversion table represents numbers used when inputting 50 syllabary characters with a key of a mobile phone on a general mobile phone. This correspondence is often displayed on the key of the mobile phone, and is a conversion table that is easy for the user to understand.

FIG. 11 shows an operation flowchart when generating display information at the time of lock using this conversion table.
In FIG. 11, a conversion rule application (S501) using a conversion table is added to FIG.
In S501, the character extracted in S303 is searched from the pre-conversion column of the conversion table (FIG. 10), and converted to the post-conversion character of the corresponding line.
If “Y” is extracted in S303, it is converted to “8”. FIG. 12 shows an example of phone book data when input is made using this conversion table.

  As described above, according to the present embodiment, by converting the display information at the time of lock using the conversion table, the display at the time of lock that is understood to some extent by the owner of the mobile phone but is more difficult to understand by the third party. Information can be generated.

Further, here, a case has been described in which characters are converted using a conversion table, but they may be automatically converted by a program.
FIG. 13 shows an operation flowchart of the lock display information generation unit 28 in this case.
11, character conversion (S601) is performed by a program instead of conversion rule application (S501) using a conversion table.
In S601, the character extracted in S303 is converted by a program.
In the conversion by the program, for example, “A” is shifted to “I”, “O” is shifted to “K”, etc., one by one in the order of the Japanese syllabary order. In the case of conversion by this program, for example, when “Y” is extracted in S303, it is converted to “Y”.
FIG. 14 shows an example of the phone book data when the phone book is inputted by performing conversion by shifting one by one in the order of the Japanese syllabary by the program.
Here, an example in which the characters are shifted one by one in the order of the Japanese syllabary has been described. However, “1” is shifted one by one in numerical order, such as “2”, “5”, or “6”. You may shift by one in order. Also, a plurality of characters may be shifted. Moreover, you may convert by another program.

  As described above, according to the present embodiment, the display information at the time of lock is converted by the program to generate the display information at the time of lock that can be understood to some extent by the owner of the mobile phone but is harder to understand by the third party. can do.

  Here, the example in which the first character of the item data of the phone book is used as a method for the lock-time display information generation unit 28 to automatically generate the lock-time display information has been described, but any partial character string of one or more characters can be used. Good.

  Alternatively, the partial character string may be extracted after converting the Yomi into Roman characters. Moreover, you may perform an extraction process about each partial character string divided | segmented by the space etc.

FIG. 15 shows an operation flowchart of the lock-time display information generation unit 28 in this case.
In FIG. 9, after item data is extracted in S301, conversion processing from katakana to romaji is performed (S701), and the first character is extracted (S702).
Furthermore, a space character in the character string is checked (S703), and if the character string is delimited by a space, processing for concatenating the character immediately after the space is also added (S704).
For example, when “Yamada Taro” is extracted in S301, it is converted to “YT”.
FIG. 16 shows an example of the phone book data when the phone book is input by performing Katakana to Romaji conversion, extracting the first character for each partial character string delimited by spaces.
Although the case where “yomi” is converted into romaji has been described here, “name” and other items may be converted from kanji to katakana or romaji.

  As described above, according to the present embodiment, by adding the process of converting to Roman characters, etc., it is possible to generate display information at the time of lock that is understood to some extent by the owner of the mobile phone but is harder to understand by a third party. Can do.

  Further, in the above description, the example using the Yomi item has been described as a method for the lock display information generating unit 28 to automatically generate the display information when locked, but the name, group, telephone number, mail address, memory number, Other items in the phone book such as an abbreviated dial number may be used.

In the above description, the lock display information is automatically generated based on one item of the phone book data. However, the lock display information may be automatically generated by combining a plurality of items.
FIG. 17 shows an example in which the first character of the reading is combined with the first character of the group name.
In this example, the process of omitting the character string “(stock)” is also performed before extracting the first character.
In this way, by omitting a specific character string that is difficult to use as a hint when the owner specifies the caller, such as “Co., Ltd.”, the character string of the display information at the time of lock is generated only from the remaining part, thereby making the caller more It is possible to generate display information at the time of locking that makes it easy to specify the.

Further, a method for generating the display information at the time of locking may be described as a rule for generating the display information at the time of locking, and the display information at the time of locking may be generated according to the rule.
FIG. 18 shows an example of the lock-time display information generation rule in which the items of the phone book data to be extracted and the extraction method for generating the lock-time display information are described in a list format.
Here, the data item string indicates telephone book data items to be used for automatic generation. In this example, the first method shows a reading, and the second method shows a group name.
The extraction method column indicates a method of generating display information at the time of locking from the value of the data item. In this example, the first and second “first N characters” are extracted. The value of N is indicated by N columns, and is “1” in the example of FIG. 18, so that “first one character” is extracted for both the first and second.
FIG. 19 shows an operation flow of the lock-time display information generation unit 28 when lock-time display information is generated based on a plurality of items according to the lock-time display information generation rule. The operation will be described below.

When the lock display information generation unit 28 is requested by the telephone directory data editing control unit 26 to generate lock display information (S400), the lock display information is initialized (S401).
Thereafter, the process is repeated for each row of the lock display information automatic generation rule (FIG. 18) (S402).
According to the original data item of the display information generation rule at the time of locking, the data of the corresponding item is acquired from the phone book data editing control unit 26 holding the phone book data being edited (S403).
In the example of FIG. 18, since the phone book data item used in the first rule is “Yomi”, the data of “Yomi” item is acquired.
Next, a specific character string is searched from the extracted “Yomi” item data and removed (S404).
An example of the specific character string used here is shown in FIG.
For example, if the reading is “Tanaka Saburo”, the specific character string is not included, and therefore “Tanaka Saburo” remains unchanged.

Next, according to the lock display information generation rule, lock display information is generated using the acquired item data (S405).
In the example of FIG. 18, since the extracted character used in the first rule is the first character, the first character of the character string obtained in S404 is extracted. For example, in the case of “Tanaka Saburo”, the first character is extracted, and the character string “Ta” is extracted.
Then, the obtained character string is linked to the lock display information (S406).
When the first rule is applied, the display information at the time of locking is in a state initialized by (S401), and therefore the character string ("T") generated at S405 becomes the display information at the time of locking.
The processing of S403 to S406 is repeated for each lock display information automatic generation rule (FIG. 18) (S402).
In the example of FIG. 18, the process is repeated twice. In the second process, the first character of the group item is extracted and connected to the display information at the time of locking. For example, if the group is “(stock) XYZ”, since the specific character string “(stock)” is removed in the process of S404, “X” is extracted and connected to the display information at the time of lock. Is obtained.
Finally, the generated display information at the time of locking (in this example, “X”) is returned to the telephone directory data editing control unit 26. The telephone directory data editing control unit 26 inputs the response information displayed at the time of lock to the display information item at the time of locking the telephone book data being edited.

  As described above, according to the present embodiment, by generating display information when locked under a plurality of conditions from a plurality of items, it is easier for the owner of the mobile phone to identify the caller and the third party can understand. It is possible to generate display information that is difficult to lock.

Moreover, you may enable it to change a display information automatic generation rule at the time of a lock | rock.
FIG. 21 shows an example of a screen for setting a lock display information automatic generation rule.
Any number of generation methods can be combined by selecting validity / invalidity of the corresponding row by the check box E42.
In the item menu E43, it is possible to select an item of the phone book data that is the basis of the display information at the time of locking.
In the rule menu E44, the conversion method of the selected item can be selected.
In the parameter input field E45, a specific value of a portion described as “N” in the selected conversion rule can be designated.
For example, when the user inputs like E41 in FIG. 21, the lock display information automatic generation rule is stored as shown in FIG. The lock display information is automatically generated according to this.
Note that the automatic display information generation rule at the time of locking may be set for each phone book group.
In this case, for each group of input telephone directory data, it is automatically generated according to the lock-time display information automatic generation rule of the corresponding group.

As described above, according to the present embodiment, by enabling the user to change the rule for automatically generating the display information when locked, the method for generating the display information when locked is easy for the owner of the mobile phone to remember Can be selected.
Further, when the user periodically changes the display information generation rule at the time of lock, the display information at the time of lock can be made more difficult for a third party to understand.

  In the above, the case where the display information is automatically generated when the phonebook data is newly registered has been explained. However, when the phonebook data is changed, the lock screen display information entry screen is displayed when the phonebook data is changed and when the lock information is not newly registered. Information may be automatically generated.

In the above description, the case where the display information at the time of lock is automatically input when editing each phone book data has been described. May be.
FIG. 23 shows an example of a screen for automatically setting display information at the time of lock. On this screen, you can select either “all cases” or “for each group”.
Further, when “for each group” is selected, a target group can be selected. After making these selections, the collective setting is executed when executed by the execute button.

FIG. 24 shows an operation flowchart of the telephone directory data edit control unit 26 when the display information at the time of locking is set collectively.
The phone book data editing control unit 26 repeats the following processing for each phone book data subject to batch setting managed by the phone book data management unit 27 (S801).
The phone book data edit control unit 26 reads one phone book data from the phone book data management unit 27 (S802).
Next, the phone book data editing control unit 26 requests the lock-time display information generation unit 28 to generate lock-time display information together with the read phone book data (S803). The operation of the lock-time display information generation unit 28 at this time is the same as described above.
The phone book data editing control unit 26 stores the lock-time display information generated and responded by the lock-time display information generation unit 28 in the phone book data management unit 27.
When the processing from S802 to S804 is repeated for all the phone book data to be collectively set (S801), the operation is completed (S899).
The collective setting of the display information for locking may be executed when data is transferred from another device or a memory card.

  As described above, according to the present embodiment, it becomes easier for the user to change the lock display information by enabling the lock display information to be set collectively.

  Also, specific characters that are difficult for a third party to identify the caller, such as symbols such as “*” and “#”, may be transferred from the phone book data item to the display information when locked. If the user inputs a specific character in an item such as a name as a hint when the caller is specified, it is transferred to the display information at the time of lock.

  As described above, according to the present embodiment, it is easier for the owner of the mobile phone to understand by transferring the specific character that is difficult for a third party to identify the caller to the display information at the time of lock. It is possible to generate lock-time display information that is difficult for the three parties to understand.

Embodiment 3 FIG.
In the first embodiment and the second embodiment, an item for storing display information for locking is provided in the phone book data. However, in the third embodiment, no special item is provided in the phone book data. An embodiment in which display information for lock is automatically generated and displayed on an incoming call screen will be described.

FIG. 25 shows a configuration diagram of the communication terminal 2 in this embodiment.
25 are the same as those in FIG. 7 of the second embodiment, and a description thereof will be omitted.
However, the display information generation unit 28 when locked is called from the telephone directory data editing control unit 26 in FIG. 7 of the second embodiment, but is called from the incoming call screen generation unit 24 in FIG. 25 of the present embodiment. It is different in that it is configured.
In other words, in the present embodiment, when the lock display information generation unit 28 (restriction setting representation information generation unit) receives an incoming call when the lock is set (display restriction setting), the name of the communication partner of the incoming call is displayed. The lock display information (representation information at the time of restriction setting) that represents the communication partner is generated without indicating. Although details will be described later, the lock-time display information generation unit 28 searches for phone book data including a phone number that matches the phone number of the communication partner received at the time of incoming call, and at least one of the searched phone book data. Is used to generate one or more character strings representing the telephone number holder without indicating the name of the telephone number holder of the searched telephone directory data, and the generated character string is used as display information at the time of lock.
Then, the incoming screen generation unit (incoming information control unit) generates the communication partner name character string on the display unit when the incoming call is received when the lock is set, and is generated by the lock display information generation unit 28 Display display information when locked.

FIG. 26 is a flowchart at the time of incoming call of the communication terminal 2 in this embodiment.
Next, the operation at the time of an incoming call will be described using FIG. 25 and FIG.

The operations in S100 to S105, S111 to S112, S114, and S199 in FIG. 26 are the same as those in FIG.
When the lock setting is released in S105 of FIG. 26, the incoming call screen generation unit 24 generates an incoming call screen including information such as the name of the telephone directory data and displays it on the display unit 21 as in the first and second embodiments. (S114, FIG. 31).
In the lock setting state, the incoming call screen generation unit 24 requests the lock-time display information generation unit 28 to automatically generate the lock-time display information (S206).
The lock display information generation unit 28 automatically generates the lock display information and returns it to the incoming call screen generation unit 24 (S206).
Upon receiving the lock display information generated from the lock display information generation unit 28, the call receiving screen generation unit 24 generates an incoming screen that displays only the lock display information and displays it on the display unit 21 (S113). .

  Here, the operation in which the lock display information generation unit 28 generates the lock display information (S206) is the same as in the second embodiment, but in the second embodiment, the telephone book data editing control unit 26 requests and responds. In contrast to this, the present embodiment is different in that the incoming call screen generation unit 24 requests generation of display information when locked and receives a response.

Hereinafter, the operation of the lock-time display information generation unit 28 in the third embodiment will be described with reference to the example of FIG. Here, as in the second embodiment, the case where the first character of the reading item is extracted as display information at the time of locking will be described.
When the lock-time display information generation unit 28 is requested by the incoming call screen generation unit 24 to generate lock-time display information together with the phone book data corresponding to the caller number (S300), the lock-time display information is received from the received phone book data. The value of the phone book data item used to generate the password is acquired (S301). In this example, since “Yomi” item data is used, “Yomi” item data is acquired.
Next, the lock display information is generated using the acquired item data (S302). In this example, the first character is extracted from the “Yomi” item data acquired in S301.
For example, if the reading is “Yamada Taro”, the first character is extracted, and the lock display information “Y” is generated.
Then, the generated lock display information (in this example, “Y”) is returned to the incoming call screen generation unit 24 (S302).

As described above, the operation of the lock-time display information generation unit 28 of the third embodiment is the same as that of the second embodiment except that the request source and the response destination of the lock-time display information generation are the incoming screen generation unit 24. It is.
The other automatic lock display information generation method described in the second embodiment can be applied to the third embodiment as well.

  As described above, according to the present embodiment, since the display information field for lock is not provided in the phone book data and is automatically generated when a call is received, the same effect as in the first embodiment can be obtained. In addition, it is possible to save the user from having to input display information for locking.

In the third embodiment, the lock display information may be generated by a different method for generating the lock display information for each incoming call.
FIG. 27 shows an example of an incoming call screen when the lock-time display information is automatically generated by a different method for each incoming call. In this example, the case where there are four incoming calls from “Taro Yamada” stored in the telephone directory shown in FIG. 34 is shown.
FIG. 28 shows a method for generating lock-time display information used for every four incoming calls.
The display information for locking at the time of the first incoming call (method A) is the first two characters of Yomi.
The display information for locking at the second incoming (method B) is a combination of the first letter of the reading and the first letter of the group name.
The display information for locking at the third incoming time (method C) is a combination of the first character of the group name and the first character of the name (kanji).
The display information for locking at the time of the fourth incoming call (method D) is a combination of the first character of the name (kanji) and the first two characters of the group name.

FIG. 29 shows an operation flowchart of the lock-time display information generation unit 28 in this case.
In FIG. 29, processing for selecting a method for generating display information at the time of locking is added to FIG. 26 (S1001).
The method for generating the display information at the time of locking is selected in order, for example, every time the display information generating unit at the time of locking 28 is called from a plurality of predetermined methods (FIG. 28).
Or you may make it select at random.

  As described above, according to the present embodiment, even if there are a plurality of incoming calls from the same caller number, the display is different every time, so even a third party has received multiple calls from the same person. There is an advantage that it cannot be recognized.

In addition, a technique for displaying different lock display information for each incoming call may be applied to the first and second embodiments.
For example, only the display information at the time of the first incoming call lock is generated by the method shown in the embodiment 1 or 2 and stored in the phone book data management unit 27. The display information at the time of locking stored in the telephone directory data management unit 27 is displayed on the display unit 21, and after the second incoming call, the display information generating unit at the time of locking shown in the present embodiment performs, for example, FIG. In accordance with the automatic generation rules shown in FIG. 5, different lock display information may be generated for each incoming call and displayed on the display unit 21.
Also, display information (N) for N incoming calls is generated by the method shown in the first or second embodiment by designating the number of incoming calls, stored in the telephone directory data management unit 27, and received when the lock is set. If there is, the corresponding display information at the time of lock may be displayed on the display unit 21 in accordance with the number of incoming calls. Or you may make it select and display at random.

As described above, the communication terminals shown in Embodiments 1 to 3 mainly have the following characteristics.
(1) When the communication terminal receives an incoming call in the lock setting state, it searches the phone book, and instead of the name and phone number, the lock screen display information that can be used to infer who the caller is only the owner. To display.

(4) Automatic generation method.
(A) Partial character strings such as name, Yomi, phone book group, mail address.
(A) A character string is converted by a conversion table.
(C) The character string is converted by a program such as alphabetical order, numerical order, and character code order.
(D) Performs Romaji conversion of character strings.
(E) Omit specific character strings such as “Co.,” which makes it difficult for the owner to identify the caller.
(F) The symbol or the like that the owner can use as a hint to identify the caller is transcribed as it is.
(G) Combination of the above.
(5) The automatic generation method is described and stored as a lock time display method generation rule, and is automatically generated according to this rule.
(A) Allow the user to change the display method generation rule for locking.
(A) Enable setting for each group.
(6) The display information for locking can be set in a lump (all cases, all groups).
(A) Automatic batch setting when data is transferred from other devices or memory cards.
(7) Without generating a column for display information for locking, automatically generating and displaying when receiving a call.
(A) By changing the automatic generation rule for each incoming call, when there are multiple incoming calls from the same caller, it is possible to prevent a third party from taking it.
