Abstract

PROBLEM TO BE SOLVED: To make a lost portable telephone into call out disabling mode from other telephones, and to make it not display registered private information. SOLUTION: When the incoming call of the predetermined number of times is performed in a setup time from one telephone in the setup time (Yes at a step 113), an information display function such as a memory dial is stopped (step 118), and then a call out is disabled (step 120 or 121). When an incoming call mode is set on 'continuation' and an incoming call from another device is performed even once on the way, the number of counts of the incoming call is reset to 1 and when the mode is set on 'normal', the incoming call from other devices during counting is disregarded.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone, and more particularly to a portable telephone provided with a countermeasure for misplacement.

[0002]

2. Description of the Related Art When a portable telephone is left somewhere, it is difficult to find out the portable telephone, as in the case of misplaced metal goods, and it is difficult for the person who picked up the telephone to return it without knowing the owner. In some cases, the person who picked up the mobile phone may use the mobile phone as it is, resulting in a large fee. This is especially likely when the mobile phone is stolen. Some portable telephones have a measure against such a problem, in which a call cannot be made unless a preset password is input. However, this requires input of a password every time a call is made, and the operation is troublesome.

[0003] Japanese Unexamined Patent Publication No. Hei 9-313687 discloses a "mobile phone with a security function". When the mobile phone is lost, the owner makes a call from another phone to the lost mobile phone. When a lost mobile phone receives this call, even if it is picked up by someone, if that person goes off-hook and responds, a normal connection is made and the call enters a call state,
If there is no response, the incoming call is stopped and the incoming call operation is stopped. A circuit for counting the number of incoming calls is provided, and when the counted number exceeds a predetermined value, the portable telephone is connected to the line, and the connection is notified to the owner of the calling side by a confirmation sound. When the owner receives this confirmation sound, the owner next inputs a preset password and transmits it to the mobile phone. When the mobile phone receives this and confirms the coincidence with the set personal identification number, it switches the operation mode of the mobile phone and notifies the calling side by a confirmation sound that the mode has been switched again. Upon confirming this, the owner goes on-hook on his telephone and finishes the operation. Here, the operation mode switched by this operation is a call mode in which a normal call is made, and a security mode exclusively for reception in which calling is disabled, and the mode is switched every time the operation is performed.
In this way, when the user notices that the mobile phone is lost or stolen, the user can perform the above-described operation from a nearby phone to put the mobile phone in the crime prevention mode, and increase the call charge for unauthorized use. Can be prevented.

[0004]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 9-3 is disclosed.
In the technique of No. 12687, a password must be input every time the operation mode is switched. For this purpose, the user cannot operate unless the user has memorized the password or has a memo or the like recording the password. However, when the user notices a loss or theft, it is preferable to perform a mode switching operation as soon as possible to prevent unauthorized use. However, if the user notices that the user does not remember the password and has no memo. You can only operate after going to your home or office where you have a memo. In addition, since the mobile phone is connected to the line by a plurality of calls for mode switching, the operation time after the connection costs a call fee, which is the same as when the security mode is canceled. There are also problems that cannot be achieved with only operations. Furthermore, the function of informing the owner of the contact information of the owner was not considered.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable telephone which can easily perform an operation for shifting to a misplaced mode and can perform the operation without repeatedly performing line connection. An object of the present invention is to provide a mobile phone in which private information is not leaked.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a counterpart terminal judging means for judging whether or not an incoming call has come from the same counterpart terminal as the previous call from the incoming call history when the call is received. First setting means for setting the incoming time and the number of incoming calls, second setting means for setting either the "normal incoming" or "continuous incoming" receiving method, and "normal incoming" set by this means. When the number of incoming calls determined as the same partner terminal by the partner terminal determining means is counted within the set incoming call time, "continuous incoming" is set by the second setting means. Counting means for counting how many times only the incoming call determined to be the same other terminal by the other terminal determining means has occurred continuously within the set incoming call time; and Count value to provide a portable telephone characterized by comprising a mode switching means for the calling prohibit mode ship when it is the set value of the number of incoming calls.

Further, the present invention is characterized in that a call control means for enabling only a call to a preset telephone number is provided when the mode switching means sets the call prohibition mode. To provide a mobile phone.

Further, the present invention does not display at least one of the memory dial information, the two-touch dial information, and the local telephone number registered in the own device when the mode switching means sets the call prohibition mode. A mobile phone is provided with a display control means.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing a schematic configuration of a mobile phone according to the present invention. A wireless unit 1 for transmitting and receiving wireless signals, a control unit 2 for performing signal processing and controlling display and sound associated with a telephone call, An operation unit 3 for inputting character data by a user, a storage unit 4 for storing a processing program and telephone directory data in the control unit 2, a display unit 5 for displaying the input character data, and converting voice to an electric signal Microphone 6
And a speaker 7 for converting an electric signal into a sound.

The control unit 2 has a mode switching processing function 21,
The storage section 4 has a message registration area 41 and a setting data area 42 to be displayed in the mode of leaving behind, which has a leaving mode setting function 22 and an incoming call counter 23. Here, it is assumed that the incoming call counter 23 is cleared when the power of the mobile phone is turned on.

The forgotten mode setting function 22 is activated by the same operation from the operation unit 3 as other functions, and is used to input a forgotten message to be displayed on the display unit when the forgotten mode is entered, and to set the forgotten mode. It is used to set an incoming call method, set the number of incoming calls and the incoming call time, and set a method of prohibiting outgoing calls when the mobile phone enters the misplaced mode. FIG. 3 shows an example of a screen when the setting function 22 is executed.
When the leaving mode setting function 22 is activated, first, FIG.
Input the message on the screen. Here, for example, the left message is 3 characters with 6 full-width characters per line.
If the line is available (this display amount may also be settable), enter "Please contact below" in the first and second lines, and enter the telephone number of the contact (home, etc.) in the third line. Is registered in the registration unit 41. Such an input can be easily realized by a function similar to the input of a telephone directory or the like. In the above message example, "Please contact the following" may be fixed and prepared in the processing system in advance, and the user may input only the telephone number.

When the input of the misplaced message is completed, the screen shown in FIG. 3B is displayed, and the method of counting incoming calls when shifting to the misplaced mode is set as the incoming call method. If you select "Normal" here, the same phone number (for number notification) or the same model (public, analog phone, etc.)
If there is an incoming call from another phone or another model, ignore it even if there is an incoming call from another phone or another model, and select "Continuous". Incoming call method.

Next, the arrival time and the like are set. This will be described in detail later in the description of the mode switching process 21. The number of incoming calls (called the number of incoming calls) in the above-described incoming call method within a certain set time (called the incoming call time) determines the number of incoming calls. Is the setting. FIG. 3C shows an example of the setting screen in which the incoming call time is set to 5 minutes and the number of incoming calls is set to 5 times. Further, when this is completed, on the screen as shown in FIG. 3D, as a method of prohibiting the call (locked state), either "call restriction" or "key lock" is selected. The above setting results are stored in the setting data area 42. Of course, these can be changed in the same manner as the memory dial or the like.

When the portable telephone set by the setting mode setting function 22 as described above is lost, the user who is the owner of the portable telephone sets another number of incoming calls within the set incoming call time. To the mobile phone from the other phone. FIG. 1 is a flowchart showing the processing of the mobile phone left-place mode switching function 21 executed at this time. This process is a part of the reception process that is periodically started, and when there is an incoming call (Yes in step 101),
Output ringtone and write incoming call history (step 10
2). Here, a mobile phone is generally provided with a function to record the incoming call history, such as the date and time of the incoming call, the type of call (different from number notification, no number notification, public telephone, analog dial telephone), The outgoing telephone number or the like at the time of the number notification is recorded for each incoming operation, and about the latest 20 cases are always recorded. If there is an off-hook, the operation shifts to a normal reception operation (step 103).
Yes), if it is lost and no one has it, it will not be off-hook. If there is no off-hook for the ringing tone (No in step 103), it is checked whether the value j of the incoming counter is 0 (step 104). This value is 0 immediately after entering the left-place mode or immediately after the power is turned on, and j ≧ 1 if there is at least one incoming call thereafter.
It has become. When j = 0, the value j of the incoming counter is set to 1 (step 105), and the process is terminated.

If the value j of the incoming call counter is not 0 (No in Step 104), the current time tb is obtained from the system clock (Step 106), and the incoming time ta before j times is obtained by referring to the incoming call history. (Step 107).
Then, it is checked whether the value of tb-ta is shorter than the arrival time T set in the area 42 by the misplacement mode setting function 22 (step 108).
At step 05, the value of the incoming counter is set to 1 and the processing is terminated. When tb-ta is shorter than the incoming time T (Yes at step 108), the incoming call type is determined by referring to the incoming call history. Check if it is the same as when receiving the call (step 10
9). Here, if the call type is the same as the last incoming call (Yes in step 109), it is checked whether the call type is a number notification (step 110). If this is a number notification, it is checked again whether the current and previous calling telephone numbers are the same by referring to the incoming call history (step 111). If the incoming call is not a number notification (No in step 110) or if the number notification is from the same telephone number as the previous time (step 111)
Is Yes), and the value j of the incoming counter is incremented by 1 (step 1).
12) It is checked whether the updated value j has reached the number of incoming calls jmax set by the misplaced mode setting function 22 (step 113), and the value j of the incoming call counter is determined to be the number of incoming calls jmax.
The process is ended in the following cases.

If the call type is different from the previous call (No in step 109), or if the telephone number is not the same in the number notification (No in step 111), the area 42
Is checked (step 114). If "continuous" is set, the counter value j is reset to 1 (step 105), and recounting is started. When the incoming call method is set to “normal”, the current incoming call is ignored and the next incoming call is waited without changing the count value j.

When the value j of the incoming call counter reaches the number of incoming calls jmax (Yes in step 113), the call is received within a time T from a telephone of the same calling type, and particularly from a telephone of the same telephone number when the number is notified. To jmax
Indicates that the number of incoming calls equal to. This is to minimize the possibility of accidentally transitioning to the misplaced mode if the mobile phone is not lost but misplaced at home, etc., and accidentally arrives jmax times within the time T. It means that the telephone number check at the time of notification of the type and the number is performed. At this time, the mode is shifted to the forgetting mode assuming that there is an instruction from the holder. That is, first, the value j of the incoming call counter is reset to 0 (step 115), and the incoming call sounds at the maximum level, for example, for 20 seconds (step 116). Thereby, it can be notified that there is a person around the mobile phone that has been left behind. Next, the left-placed message set by the left-behind mode setting function 22 is displayed on the display unit 5 as shown in FIG. 4 (step 117), and the various functions are stopped in accordance with the transition to the left-behind mode (step 117). Step 118). This is to prevent private information from being displayed, or to erase such information so that it is not known to others, as described above. For this reason, in this processing, each of the memory dial display, the two-touch dial transmission, and the own-station telephone number display is prohibited. Specifically, when entering the misplaced mode, the mode flag is set to a value indicating “prohibited”, and when the above-mentioned functions are called, the mode flag is referred to and when this is “prohibited”, the function is skipped. It is good to keep it. When the stop processing is completed, the method of prohibiting the call set by the leaving mode setting function 22 is also checked (step 119), and the call restriction or the key lock is turned ON accordingly (step 120 or 121), and the processing ends.

However, even if the transmission is restricted or the key is locked, if any key (for example, a call key) is pressed during the display of the misplaced message as shown in FIG.
Be prepared to call the contact telephone number indicated in the misplaced message. Thus, in the case where the mobile phone is lost, the finder can contact the owner of the mobile phone by a simple method without placing an economic burden. In addition, it is not necessary to display the telephone number in the misplaced message. In this case, it is possible to prevent leakage of the personal information of the owner of the mobile phone.

As described above, if the lost portable telephone is set to the calling prohibited state, it is impossible to make a call to a contact telephone number other than the previously registered contact telephone number, and otherwise, only the reception is possible. State. In this way, according to the processing of FIG. 1, a mobile phone lost due to a call from a nearby phone can be placed in a call prohibited state without using a password.
In other words, the mode can be set to the forget-to-place mode, and no call charge is required. In addition, even when an incoming call from another device is assumed during an operation for prohibiting a call, setting of the incoming call method facilitates the transition to the misplaced mode. Further, private information registered in the mobile phone can be protected. It should be noted that a function key is assigned to the release mode, and the password can be released by inputting a password in the release mode. There is no urgency compared to the shift to call prohibition to prevent abuse in the event of loss, and even if you forget your PIN, you only have to wait until you read the memo, etc. The use of the password for the password is necessary so that the misplacement mode cannot be canceled by others.

[0020]

According to the present invention, a lost portable telephone can be placed in a call-inhibited mode without calling charges without using a personal identification number, and an improper charge can be added. Can be prevented. Further, the operation for setting the mode to be left behind becomes easy, and there is an effect that the registered private information can be prevented from leaking to others.
