Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone, and more particularly, to a mobile phone provided with a measure against misplacement.
[0002]
[Prior art]
If you leave your mobile phone somewhere, it will not be as easy to find as if you left your money away, and it will be difficult for the owner to pick it up and return it. In some cases, the person who picks up uses the mobile phone as it is, and pays a large fee. This is especially likely when a mobile phone encounters theft. Some portable telephones having a countermeasure against such a problem are such that a call cannot be made unless a preset password is inputted. However, this requires a password input each time a call is made, which is cumbersome to operate.
[0003]
Japanese Patent Laid-Open No. 9-312687 discloses “a mobile phone with a crime prevention function”. When this mobile phone is lost, the owner calls it from another phone to the lost mobile phone. A lost mobile phone that receives this call will be connected to a normal connection if it is picked up by someone and responds with an off-hook response. Is also stopped. A circuit for counting the number of incoming calls is provided, and when the count exceeds a predetermined value, the mobile phone is connected to the line, and the connection side is notified to the calling party owner by a confirmation sound. When the owner receives this confirmation sound, the owner then inputs a preset password and transmits it to the mobile phone. When the mobile phone side receives this and confirms the coincidence with the set personal identification number, the operation mode of the mobile phone is switched, and the calling side is notified by a confirmation sound that mode switching has been performed again. The owner who confirms this ends the operation by on-hooking his / her telephone. Here, the operation mode switched by this operation is a call mode for performing a normal call and a reception-only security mode for disabling a call, and the mode is switched every time the above operation is performed. In this way, when the user becomes aware of the loss or theft of a mobile phone, the user can perform the above-described operation from a nearby phone to put the mobile phone into a security mode, and add up to the call charge due to unauthorized use. Can be prevented.
[0004]
[Problems to be solved by the invention]
In the technique disclosed in Japanese Patent Laid-Open No. 9-312687 described above, it is necessary to input a personal identification number every time the operation mode is switched. For this purpose, the user cannot operate unless the personal identification number is stored or a memo or the like recorded therein is recorded. However, if you notice a loss / theft, it is preferable to switch the mode as soon as possible to prevent unauthorized use. However, if you do not remember your PIN and do not have a memo , You can only operate after going to your home or office where the notes are. In addition, since the mobile phone is connected to the line by making multiple calls for mode switching, the operation time after connection is charged a call fee, and this is the same when canceling the crime prevention mode. There is also a problem that cannot be done with only the operation. Furthermore, the function of notifying the contact person of the owner of the person who picked it up was not considered.
[0005]
An object of the present invention is to provide a mobile phone that is easy to shift to the misplaced mode and that can be operated without having to connect the line many times. The object is to provide a mobile phone that does not leak.
[0006]
[Means for Solving the Problems]
To achieve the above object, the present invention includes a mating terminal determination means for determining a call type of the remote terminal, the caller's telephone number when an incoming call, and setting means arrival time and number of incoming calls , when the incoming from the same of the remote terminal is turned many times counting means for counting there was the value of the number of incoming calls the count value of the count means is the set of the set arrival time processing means for the own device and call inhibition mode, the state of being a call prohibition mode by the processing unit, comprises a call control means for allowing only call to a preset telephone number, the A mobile phone is provided.
[0007]
Further, the present invention provides a counterpart terminal determination means for determining the call type and caller telephone number of the counterpart terminal when there is an incoming call, a means for setting the incoming time and the number of incoming calls, and an incoming call from the same counterpart terminal Counting means for counting the number of times the mobile phone is within the set incoming time, and a process for setting the own device to a call prohibition mode when the count value of the counting means reaches the set number of incoming calls and means, in the state of being a call prohibition mode by said processing means, display control means so as not to display at least one of the apparatus itself memory dial information registered in, 2-touch dialing information or local telephone number, , to provide a mobile telephone, characterized in that it comprises a.

According to another aspect of the present invention, there is provided a mobile phone characterized by displaying a preset misplacement message in a state in which the processing means is in a call prohibition mode.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described 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 that transmits and receives wireless signals, a control unit 2 that controls signal processing, display, and sound generation associated with a call, An operation unit 3 for a user to input character data, a storage unit 4 for storing a processing program and telephone book data in the control unit 2, a display unit 5 for displaying the input character data, and converting voice into an electrical signal And a speaker 7 for converting an electrical signal into sound.
[0010]
The control unit 2 has a mode switching processing function 21, a misplacement mode setting function 22, and an incoming call counter 23, and the storage unit 4 has a message registration area 41 and a setting data area 42 that are displayed in the misplacement mode. Here, it is assumed that the incoming call counter 23 is cleared when the mobile phone is powered on.
[0011]
The misplacement mode setting function 22 is activated by an operation from the operation unit 3 similar to the other functions, and is used to input a misplacement message to be displayed on the display unit or to enter the misplacement mode when the misplacement mode is set. It is used for setting the incoming call method, setting the number of incoming calls and incoming time, and setting the method of prohibiting outgoing calls when the misplaced mode is entered. FIG. 3 shows an example of a screen when this setting function 22 is executed. When the forgetting mode setting function 22 is activated, a forgetting message is first input on the screen as shown in FIG. For example, if you leave 3 messages with 6 full-width characters per line (this display amount can be set), the first and second lines are “Please contact below”, 3 lines The telephone number of the contact (home, etc.) is input to the eye, and this is registered in the registration unit 41. Such an input can be easily realized with the same function as the input of a telephone directory or the like. In the above message example, “Please contact below” may be fixed and prepared in advance in the processing system, and the user may input only the telephone number.
[0012]
When the input of the misplaced message is completed, the screen of 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, you can receive calls from the same phone number (for number notification) or from the same model (public, analog phone, etc.), even if there is an incoming call from another phone or other model. If the count is ignored and “continuous” is selected, if there is an incoming call from another number or other model in between, the incoming call system starts over from 1.
[0013]
Next, the incoming time is set. This will be described in detail later in the description of the mode switching process 21. How many times (called the number of incoming calls) the incoming call method is used within a certain set time (called incoming time), the mode switching is executed. This is the setting. FIG. 3C shows an example of the setting screen in which the incoming time is set to 5 minutes and the number of incoming calls is set to 5 times. Further, when this is finished, either “Call Restriction” or “Key Lock” is selected as a method of call prohibition (lock state) on the screen as shown in FIG. Each setting result described above is stored in the setting data area 42. Of course, these can be changed in the same manner as the memory dial or the like.
[0014]
When the mobile phone set by the misplacement mode setting function 22 as described above is lost, the user who is the owner of the mobile phone makes a call for the number of incoming calls set within the set incoming time from another phone. Perform for the mobile phone. FIG. 1 is a flowchart showing processing of the cellular phone misplacement mode switching function 21 executed at this time. This process is a part of the reception process that is periodically activated. When there is an incoming call (Yes in Step 101), a ring tone is output and an incoming call history is written (Step 102). Here, mobile phones are generally provided with a function to collect incoming calls, and the date and time of incoming calls, the type of call (distinguishing between number notification, number non-notification, public phone, analog dial phone), The outgoing telephone number and the like at the time of number notification are recorded for each incoming call operation, and the latest 20 cases are always recorded. If there is an off-hook here, the operation shifts to a normal reception operation (Yes in step 103). However, if it is lost and nobody has it, it is not off-hooked. Therefore, if there is no off-hook for the ringing tone (No in Step 103), it is checked whether the value j of the incoming call counter is 0 (Step 104). This value is 0 immediately after the misplacement mode is entered or immediately after the power is turned on, and j ≧ 1 if there is even one incoming call thereafter. When j = 0, the incoming counter value j is set to 1 (step 105), and the process is terminated.
[0015]
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 106). 107). Then, it is checked whether the value of tb-ta is smaller than the incoming time T set in the area 42 by the misplaced mode setting function 22 (step 108). If not smaller, the value j of the incoming counter is set to 1 in step 105 and processed. However, 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 with reference to the incoming call history (Step 109). If the call type is the same as the previous call type (Yes in step 109), it is checked whether the call type is number notification (step 110). When this is a number notification, the incoming call history is again referenced to check whether the current and previous caller telephone numbers are the same (step 111). If the incoming call is not a number notification (No in step 110), or if it is a number notification from the same telephone number as the previous time (Yes in step 111), the incoming counter value j is incremented by 1 (step 112) and updated It is checked whether or not the value j has reached the number of incoming calls jmax set by the misplacement mode setting function 22 (step 113). If the value j of the incoming call counter is less than or equal to the number of incoming calls jmax, the processing is terminated.
[0016]
When the call type is different from the previous time (No in Step 109), or when the telephone number is not the same in the number notification (No in Step 111), the incoming call method set in the area 42 is checked (Step 114). When “continuous” is set, the counter value j is reset to 1 (step 105), and re-counting is started. When the incoming call method is set to “normal”, the current incoming call is ignored, and the next incoming call is awaited without changing the count value j.
[0017]
When the value j of the incoming call counter is equal to the number of incoming calls jmax (Yes in step 113), the number of incoming calls within the incoming time T from the telephone of the same call type, and particularly from the telephone of the same telephone number for number notification. This indicates that there are incoming calls equal to jmax. This is done to prevent a mistaken transition to the misplaced mode if there is an incoming call jmax times within the incoming time T, such as when the mobile phone has not been lost but is left at home. This means that the telephone number was checked when the type and number were notified. At this time, the mode shifts to the misplacement mode because there is an instruction from the owner. That is, first, the value j of the incoming call counter is reset to 0 (step 115), and the incoming sound is sounded at the maximum level for 20 seconds, for example (step 116). Thereby, it can be notified that there is a person around that there is a mobile phone that has been misplaced. Next, the misplacement message set by the misplacement mode setting function 22 is displayed on the display unit 5 as shown in FIG. 4 (step 117), and then various functions are stopped when the misplacement mode shifts (see FIG. 4). Step 118). As described above, this is to prevent private information from being displayed or to erase such information so that it is not known to others. For this reason, in this process, each of memory dial display, two-touch dial transmission, and local telephone number display is prohibited. Specifically, when the misplaced mode is entered, the mode flag is set to a value indicating “prohibited”, and when this function is called, the mode flag is referred to, and when this is “prohibited”, the function is skipped. Just keep it. When this stop process is completed, the call prohibition method set by the misplacement mode setting function 22 is also checked (step 119), and the call restriction or key lock is turned on accordingly (step 120 or 121), and the process ends.
[0018]
However, even if the outgoing call restriction or key lock state is set, if any key (for example, a call key) is pressed while the misplaced message is displayed as shown in FIG. 4, the call is made to the contact telephone number displayed in the misplaced message. Be ready to call. This makes it possible to contact the owner of the mobile phone by a simple method without burdening the financial user, such as when the mobile phone is lost. Note that the telephone number need not be displayed in the misplaced message, and in this case, leakage of personal information of the owner of the mobile phone can be prevented.
[0019]
As described above, if a lost mobile phone is placed in a call-prohibited state, calls can only be made to contact telephone numbers that have been registered in advance, and otherwise only reception is possible. . Thus, according to the processing of FIG. 1, a mobile phone lost due to a call from a nearby telephone can be placed in a call prohibition state, that is, a misplacement mode without using a personal identification number. No call charges are required. In addition, even when an incoming call from another device is assumed during an operation for prohibiting outgoing calls, it is easy to shift to the misplaced mode by setting the incoming call method. Furthermore, private information registered in the mobile phone can be protected. Note that the release of the misplaced mode can be performed by assigning a function key to the release mode and inputting the personal identification number in the release mode. Canceling the misplaced mode is not as urgent as shifting to call prohibition to prevent abuse when lost, and if you forget your PIN, just wait for use until you see a note etc. The use of a personal identification number is necessary for preventing others from leaving the misplaced mode.
[0020]
【The invention's effect】
According to the present invention, a lost mobile phone can be placed in a call-forbidden forgetting mode without calling charges even without using a personal identification number, and an unfair charge can be prevented from being added. Also, the operation for setting the misplacement mode becomes easy, and there is an effect that the registered private information can be prevented from being leaked to others.
