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 Application 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 of the above-mentioned Japanese Patent Application No. 9-312687, 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]
The object of the present invention is to make a call prohibition state from a remote location without entering a password or connecting to a line, and at that time a person near the mobile phone is notified by ringing to contact the owner. It is an object of the present invention to provide a mobile phone that can also display and the like.
[0006]
[Means for Solving the Problems]
The present invention provides a setting means for setting an incoming time and the number of incoming calls, a counter for counting how many incoming calls that are not off-hooked during the set incoming time, and a count value of the counter as a value of the number of incoming calls. Disclosed is a mobile phone comprising a mode switching means for setting a call prohibition mode when the time is up.
[0007]
Furthermore, the present invention discloses a mobile phone characterized by comprising a misplaced message display means for displaying a pre-registered misplaced message on the display means when the call prohibit mode is entered.
[0008]
Furthermore, the present invention discloses a cellular phone characterized by comprising a misplaced sounding means for sounding a ringtone at its maximum level when the call prohibiting mode is set.
[0009]
Further, the present invention provides a call discrimination means for comparing the call types of the current call and the previous call from the call reception history when there is an incoming call, and resetting the counter value to 1 if they do not match. Disclosed is a mobile phone that is provided.
[0010]
Furthermore, the present invention takes out the call types of the current call and the previous call from the call reception history when there is an incoming call, and the call types are both number notification and the telephone numbers are different. Discloses a mobile phone characterized by comprising a number distinguishing means for resetting the value of the counter to 1.
[0011]
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. The control unit 2 has a mode switching processing function 21, a misplacement mode setting function 22, and an incoming call counter 23, which are features of the present invention, and the storage unit 4 has a message registration area 41 that is displayed in the misplacement mode. Here, it is assumed that the incoming call counter 23 is cleared when the mobile phone is powered on.
[0012]
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 to set the number of incoming calls and the incoming time and to set a 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.
[0013]
When the input of the misplaced message is finished, the incoming time is set next. This will be described in detail later in the description of the mode switching process 21, or is a setting of how many times (called the number of incoming calls) are received within a certain set time (called incoming time) to perform the mode switching. FIG. 3B shows an example of the setting screen where 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.
[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 from the other phone within the set incoming time. To do. 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 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 the process is terminated. However, when 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 they are not the same, the value j of the incoming call counter is set to 1 in step 105 and the processing is terminated. If the call type is the same as the previous call (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 referred again to check whether the current and previous caller telephone numbers are the same (step 111). If they are different, the incoming call counter value j is set to 1 in step 105. To finish. 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 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 is not 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 114), and the incoming call is sounded at the maximum level for 20 seconds, for example (step 115). 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 116). Are checked (step 117), the call restriction or key lock is turned on accordingly (step 118 or 119), and the process ends.
[0017]
If the lost mobile phone is in a call-prohibited state as described above, only the reception is possible, and a call cannot be made until the call prohibition is canceled. 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. 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.
[0018]
【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. Further, by displaying a sound and a misplaced message in the misplaced mode, it is possible to notify the person who picked it up or a nearby person of its existence or to inform the contact information of the owner.
