Abstract

PROBLEM TO BE SOLVED: To inhibit a lost portable telephone from being called from another telephone set and, in addition, from displaying registered private information. SOLUTION: When incoming calls are made by a set number of times from the same telephone set during a set period of time ('Yes' in a step 113), an information displaying function, such as the memory dial, etc., is stopped (step 118) and call out is inhibited (steps 120 or 121). For counting the number of incoming calls, the counted number is reset to '1' when incoming calls are made from other telephone sets even when the number of incoming calls is only one during the counting operation in the case where the call-in system is set to 'Continuous'. When the call-in system is set to 'Normal', incoming calls made from other telephone sets are ignored during the counting operation.

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 If a portable telephone is left somewhere, it is difficult to find it, as in the case of misplaced money and the like, and it is difficult for the person who picked up the telephone to return it without knowing its 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 calling side owner 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. After 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 cannot be made, and the mode is switched every time the operation is performed.
In this way, when the user notices the loss or theft of the mobile phone, the user can perform the above-described operation from a nearby phone to set 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. Another object of the present invention is to provide a mobile phone that prevents private information from leaking and that informs the other party of the caller in the misplaced mode.

[0015]

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 unit 4 has a message registration area 41 and a setting data area 42 which are displayed in the misplaced mode. 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, or to receive an incoming call for entering forgotten mode. It is used to set the method, the number of incoming calls and the incoming call time, and to set a method of prohibiting calling 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 misplaced mode setting function 22 is activated, first, a misplaced message is input on a screen as shown in FIG. Here, as the misplaced message, for example, 1
If it is possible to use three lines with six full-width characters (this display amount may be settable), the first and second lines are "Please contact below", and the third line is a telephone number for contact information (home, etc.) A number is input and 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, a screen shown in FIG. 3B is displayed next, and the incoming call counting method 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 incoming call 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.

The above-mentioned misplaced mode setting function 22
If you lose a mobile phone that has been configured by
The user who is the owner makes a call from the other telephone to the mobile telephone with the set number of incoming calls within the set incoming time. FIG. 1 is a flowchart showing the processing of the mobile phone left behind 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)
s) Output a ringtone and write a call history (step 102). Here, a mobile phone is generally provided with a function to keep a history of incoming calls, and the date and time of the incoming call, the type of call (number notification, no number notification, public phone, or phone with no number notification) ), The outgoing telephone number and the like at the time of the number notification are recorded for each incoming call 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 10).
If Yes in 3), it is not off-hook if lost and nobody has it. So, for the ringtone,
If there is no off-hook (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 misplaced mode or immediately after the power is turned on, and j if there is at least one incoming call thereafter
≧ 1. When j = 0, the value j of the incoming counter is set to 1 (step 105), and the process is terminated.

Further, in a state where there is no off-hook even when an incoming call is received, a flag for determining whether or not the misplacement function is being activated (misplacement mode flag) is ON (step 12).
2), the operation enters a response message transmission activation operation (step 123). As a response message, for example, message data such as "Launch mode is activated" is automatically read from the memory, and is automatically transmitted to the other party's calling party. As a result, the other party's caller, for example, the owner of the telephone set that has been left behind, knows that the telephone is left behind.

When the value j of the incoming 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 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 misplaced mode setting function 22 (step 108). If not, the value j of the arrival counter is set to 1 in step 105 and the processing is performed. Although the process ends, if tb-ta is smaller than the incoming time T (Yes in step 108), it is checked whether the call type of the current incoming call is the same as that of the previous incoming call by referring to the incoming call history (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).
If it is less than x, the process is terminated.

If the call type is different from the previous call (No in step 109) or if the telephone numbers are 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 incoming call is received from a telephone of the same call type, and particularly from a telephone of the same telephone number in the case of a number notification, within the receiving time T. To jmax
Indicates that the number of incoming calls equal to. This is to prevent the mobile phone from being erroneously shifted to the misplaced mode if the mobile phone is not lost but misplaced at home, etc., and if there is an incoming call jmax times within the incoming time T, the calling type and This means that the telephone number was checked when the number was notified. At this time, it is assumed that there is an instruction from the holder, and the mode shifts to the misplaced mode. That is, first, the value j of the incoming call counter is reset to 0 (step 115), and the ring tone is set to the maximum level, for example, 2
A sound is made for 0 seconds (step 116). As a result, it can be notified that there is a person around the mobile phone that is left behind. Next, the misplaced message set by the misplaced mode setting function 22 is displayed on the display unit 5 as shown in FIG. 4 (step 117), and then the various functions are stopped according to the misplaced mode transition (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 call prohibition method set by the forgotten mode setting function 22 is checked (step 11).
9) According to this, the transmission restriction or the key lock is turned ON (step 120 or 121), the misplaced mode flag is turned ON (step 124), and the process ends. The clearing process of the misplaced mode flag is performed when the function release process is performed.

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. It is also possible to operate step 123 after entering the call prohibition mode (steps 118 and 119).
In this case, the starting process in step 103 of step 123 may be left or eliminated. Further, activation of step 123 is performed in steps 103 and 118.
In addition to (119), the program may be started from any of steps 108 to 117.

As described above, if the lost portable telephone is set to the calling prohibited state, it is impossible to make a call to a telephone number other than the contact telephone number registered in advance, and only to receive the other telephone numbers. 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 misplacement 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 in the release mode by inputting a password. Canceling the misplaced mode is less urgent than transitioning to calling prohibition to prevent misuse when lost, so even if you forget your PIN, you only have to wait until you read the memo etc. The use of a password is necessary so that others cannot cancel the misplaced mode without permission.

Although the process of FIG. 1 has been described as a part of the reception process that is periodically activated, it is assumed that the system enters the misplaced mode when there is an incoming call and the device is not off-hook, and the steps 106 to 123 are operated under the misplaced mode. This may be performed for all incoming calls, a leaving mode release condition may be set, and when the leaving condition is satisfied, the leaving mode may be released. The conditions for canceling the misplacement include No in Step 108 and Step 10
Step 11 obtained through 9, 110, 111, 114
No. 4, Step 113 No, Steps 120, 1
After the ON setting of 21 is performed. However, functionally, even if such a processing method is adopted, it is the same as the function of FIG.

[0028]

According to the present invention, a lost mobile phone can be placed in a call-inhibited mode without calling charges without using a personal identification number, thereby preventing improper charges from being added. it can. In addition, the operation for setting the misplaced mode becomes easy, and the registered private information can be prevented from leaking to others. Further, according to the present invention, it is possible to confirm whether or not the misplaced mode has been activated, and when a third party calls, the third party can be made to lose his / her current status and cannot be used. It is not necessary to apply.
