Once the alarm mode is set, the terminal 10A limits the setting of a power-OFF mode wherein the power source is turned off, so that the sounding of an incoming indication tone is continued. Consequently, it is easily found that the terminal 10A having been lost is illegally possessed and the illegal use of the terminal 10A is surely prevented. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a radio communication system, a management server, a mobile radio terminal, and a warning mode control method for setting a specific function for a mobile radio terminal such as a mobile phone. In particular, the present invention relates to a wireless communication system, a management server, a mobile wireless terminal, and a warning mode control method that restrict unauthorized use of a mobile phone when the mobile phone is lost or stolen.

  Some mobile phones are provided with a function of prohibiting unauthorized use that restricts unauthorized use of the mobile phone. For example, when a user loses his / her mobile phone, he / she calls a mobile phone that has been lost by another telephone device, and when a specific message string is transmitted from the other telephone device to the lost mobile phone, the power is turned on. There has been proposed a technique for setting an abuse prevention mode to stop a predetermined function such as a function to be turned off (see, for example, paragraph numbers “0015” to “0017” and “0020” to “0022” of Patent Document 1).

  In addition, a technology has been proposed in which a lost mobile phone is set to a call prohibition mode only by a call from another phone without using a personal identification number, and for example, a ringing tone is generated at a maximum level for a predetermined time. (For example, see paragraph number “0016” of Patent Document 2).

Further, in the memory 26, owner identification information (terminal identification data) for specifying the mobile phone 10 and record identification data (set password data) corresponding to the password data input by the input key of the input device 22 are stored. , Stored in advance.

  The main control unit 13 controls the overall operation of the mobile phone 10, and performs processing based on the operation when the input key or the power key 23 of the input device 22 is operated, for example. The sound source data circuit 19 is a part of the main control circuit 13 and corresponds to, for example, a DSP (Digital Signal Processor). The sound source data circuit 19 generates sound source data such as an alarm sound in the warning mode.

  The radio circuit 12 constitutes a part of transmission means or reception means, and transmits and receives radio signals to and from the base station 32 shown in FIG. The audio control circuit 18 constitutes a part of warning means, and connects the receiver 14, the microphone 15, the earphone jack 16, and the speaker 17.

The management server 28 makes, for example, “address, telephone number (data), SIM number (data), IMEI number (data), communication status (data), position information, owner, Identification information (registered identification data) and “is recorded in association with each other.

  The address is written in alphabets such as 狽 #, for example. The telephone number (data) is telephone number data in the mobile phone 10 contracted with the theft / loss center. The communication state (data) is data indicating whether the current mobile phone 10 is located outside or within the service area and is in a communicable state. The position information is current position data in the mobile phone 10. The owner identification information is data for identifying the owner of the mobile phone 10, and is, for example, network PIN data set by each owner when making a contract with the theft / loss center. The owner identification information corresponds to the terminal identification data recorded in the memory 26 of the mobile phone 10A.

(Operation of this embodiment)
Next, processing related to the warning mode in the mobile phone 10 and the management server 28 will be described with reference to FIGS. Here, the processing (warning setting mode, warning mode, warning canceling mode, and power-on mode) in the stolen / lost mobile phone 10A is executed by the main control circuit 13 of the mobile phone 10A shown in FIG. This is represented by the flowchart of FIG. These programs are stored in advance in the program area of the memory 26 (see FIG. 2).

  1 is represented by the flowchart of FIG. 4 executed by the control circuit 28 of the management server 28. This program is stored in advance in the program area of the memory 31 (see FIG. 1).

  As a premise of the flowchart in the warning setting mode shown in FIG. 4, the following processing is performed on the unspecified telephone (unspecified contact terminal) and the management server 28 in the fixed telephone 40 or the mobile phone 10 </ b> B. When the owner (user) of the mobile phone 10A notices theft or loss, the owner of the mobile phone 10A places a call to the management server 28 from the mobile phone 10B or the fixed phone 40, which is an unspecified contact terminal.

  When receiving an incoming call from the mobile phone 10B or the fixed phone 40, the management server 28 transmits a message “prompt input of telephone number data or owner identification information” to the mobile phone 10B or the fixed phone 40, for example. The telephone number data and owner identification information (terminal identification data) of the mobile phone 10A are input by the input key of the input device 22 of the mobile phone 10B. The terminal identification data is configured as special data different from normal telephone number data. This is the premise process in the warning setting mode. The warning setting mode process will be described below with reference to FIG.

(Warning setting mode for unspecified phones)
In FIG. 4, in step 100, for example, the main control circuit 13 (see FIG. 2) of the mobile phone 10B (unspecified telephone) receives terminal identification data (DTMF) input by the input key of the input device 22 shown in FIG. Signal) is transmitted to the management server 28 shown in FIG. In step 102, the main control circuit 13 determines whether or not the message data is received from the management server 28 by the radio circuit 12 shown in FIG. If step 102 is positive, that is, if message data is received, in step 104, the main control circuit 13 outputs the message data as audio data or image data.

  There are two types of message data: when the warning mode is set and when not set. For example, when setting to the warning mode, the message is an affirmative message data stating that “identification has been confirmed and the mobile phone will be set to warning mode”. If the warning mode is not set, “identification cannot be performed. Therefore, the message is negative message data indicating that the mobile phone cannot be set to the warning mode. When the process of step 104 is completed, the process of this flowchart is terminated.

(Warning setting mode in the management server 28)
4, in step 200, it is determined whether the control circuit 29 (see FIG. 1) of the management server 28 has received the telephone number data and owner identification information (terminal identification data) of the mobile phone 10A. When step 200 is affirmative, that is, when terminal identification data is received, in step 202, the control circuit 29 reads “a series of terminal information associated with the terminal identification data (see FIG. 3)” from the database 36 shown in FIG. "Is read out. For example, the database 36 (see FIG. 1) that has received the terminal information read command relating to the telephone number (090-1234-5678) at the address 狽 # transmits the terminal information to the management server 28 shown in FIG.

  In step 204, the control circuit 29 of the management server 28 compares the terminal identification data with owner identification information (registered identification data) stored in advance in the database 36, and determines whether or not they match. If step 204 is negative, that is, if they do not match, the control circuit 29 transmits the negative message data described above to an unspecified telephone in the fixed telephone 40 or the mobile telephone 10B in step 206. Then, when the process of step 206 ends, the process of this flowchart ends.

  On the other hand, if step 204 is affirmative, that is, if they match, in step 208, the control circuit 29 transmits the affirmative message data described above to the unspecified telephone. In step 210, the control circuit 29 performs a calling process based on the telephone number data of the mobile phone 10A in the terminal identification data. That is, the control circuit 29 of the management server 28 performs a transmission process similar to a normal transmission to the stolen mobile phone 10A.

  In this case, the management server 28 transmits the caller number data as special number data (special number data) different from the generally used telephone number data. For example, the special number data (warning setting data) is set in advance to “9999”. On the other hand, the stolen mobile phone 10A of the present embodiment is protected in advance so that incoming call rejection cannot be set for the caller ID notification corresponding to the special number data. For this reason, the stolen mobile phone 10A always receives an incoming call when it is called using the special number data as a caller number.

(Warning setting mode in the stolen mobile phone 10A)
The process of the mobile phone 10A (see FIG. 1) in FIG. 4 starts when the power of the mobile phone 10A is turned on. In step 300, the main control circuit 13 (see FIG. 2) of the mobile phone 10A determines whether or not “warning setting (data)” is recorded (registered) in the memory 26 shown in FIG. If step 300 is negative, that is, if warning setting data is not registered, the main control circuit 13 determines in step 302 whether there is an incoming call. If step 302 is affirmative, that is, if there is an incoming call, the main control circuit 13 determines in step 304 whether the caller ID data is the above-mentioned “special number data (warning setting data)”.

  When determining whether or not there is an incoming call in step 302, if the power of the mobile phone 10A is off, the mobile phone 10A waits for the power to be turned on. On the other hand, the management server 28 transmits the terminal identification data every predetermined time, for example, every minute, until the mobile phone 10A receives (receives) terminal identification data (including caller ID data). Then, the cellular phone 10A whose power is turned on waits for transmission of the terminal identification data from the management server 28 (see step 210 and step 302).

  If step 304 is negative, that is, if the caller ID data is not a special number data but a telephone number data that is generally used, the main control circuit 13 sounds a ringing tone (ring) such as a ringtone in step 306. To start. In step 308, the main control circuit 13 determines whether or not the call key in the input device 22 shown in FIG. 2 has been pressed (operated). If step 308 is positive, that is, if the call key is pressed, the main control circuit 13 stops calling in step 310. In step 312, the main control circuit 13 performs call processing that enables communication with other terminals.

  When the call processing at step 312 ends (end of call), the process returns to step 302 and waits for an incoming call. If step 304 is affirmative, that is, if the caller ID data is special number data, the main control circuit 13 performs warning mode processing (see FIG. 5) in step 314. The warning mode process will be described below with reference to FIG. In the warning mode, in order not to notify the third party who possesses the stolen mobile phone 10A that the warning setting mode is set (to prevent unauthorized use of the mobile phone 10A in advance and reliably) Do not ring for ringtones (ringing operation). The incoming call operation includes a case where the mobile phone 10A is vibrated in addition to the ringing sound.

(Warning mode)
5, in step 400, the main control circuit 13 (see FIG. 2) of the mobile phone 10A records (registers) “warning setting (special number data)” in the memory 26 shown in FIG. For example, in this case, a flag for “warning setting” is set and the flag is set to “1”. In step 402, the main control circuit 13 (see FIG. 2) turns off (cuts off) the power supply to the non-contact IC 21 (see FIG. 2) by controlling the power control circuit 24 shown in FIG. When the power supply to the non-contact IC 21 is turned off, the non-contact data communication function is limited and cannot be used.

  In step 404, the main control circuit 13 restricts the setting in the mode in which the supply of power is turned off (power cut-off mode in which the power is cut off). Specifically, in step 404, when the power key 23 shown in FIG. 2 is operated when the power is turned on, that is, the setting of the power cut-off mode for cutting off the power supply (power supply) in the battery 25 is restricted, and the main control circuit 24 ( Power is supplied to the speaker 17 or the like including the audio control circuit 18 and the sound source data circuit 19.

  In step 406, the main control circuit 13 starts sounding of an alarm sound (alarm data) by controlling the sound source data circuit 19 of the sound control circuit 18 shown in FIG. The alarm data is set to be output (continue) only to the speaker 17 without being output to the headphone HP even when the headphone HP is connected to the earphone jack 16, for example. Further, the volume adjustment for the above sound is limited, and the sound is output at a high sound volume (for example, 300 mW). Further, in this case, since the setting of the power shut-off mode is restricted in step 404, the alarm sound continues even if the power key 23 is operated when the power is turned on.

  In step 408, the main control circuit 13 determines whether or not the password number data (warning release data) input with the input key of the input device 22 has been input. If step 408 is affirmative, that is, if password data is input, in step 410, the main control circuit 13 sets the set password data (recorded password data previously recorded in the memory 26) from the memory 26 shown in FIG. Read out.

  In step 412, the main control circuit 13 determines whether or not the password number data input with the input key of the input device 22 matches the set password number data recorded in advance in the memory 26. If step 412 is affirmative, that is, if the code number data matches the set code number data, the main control circuit 13 deletes (changes) the “warning setting (data)” registered in the memory 26 in step 414. . For example, in this case, the “warning setting” flag is defeated and the flag is set to “0”.

  In step 416, the main control circuit 13 stops the sounding of the alarm sound by controlling the sound source data circuit 19 of the sound control circuit 18 shown in FIG. In step 418, the main control circuit 13 cancels the restriction setting for the power shutdown mode. Specifically, step 418 is set to enter the power shut-off mode when the power key 23 is operated when the power is turned on.

  In step 420, the main control circuit 13 controls the power supply control circuit 24 to turn on the power supply to the non-contact IC 21 and supply power to the non-contact IC 21. When the power is supplied to the non-contact IC 21, the non-contact IC 21 can be used. When the process of step 420 is completed, the process proceeds to step 302 shown in FIG. 4 (see arrow “A”) and waits for an incoming call.

  If step 412 is negative, that is, if the code number data does not match the set code number data, in step 422, the main control circuit 13 inputs the code number data a predetermined number of times (for example, based on the count number of a counter not shown). 3 times) or not. If step 422 is negative, i.e., within the predetermined number of times, in step 424, the main control circuit 13 determines whether or not the PIN code data is input again. When step 424 is affirmative, that is, when the password data is input again, the process returns to step 412 and the main control circuit 13 determines whether or not the password data again matches the set password data.

  If step 424 is negative, that is, if the password data is not input again, in step 426, the main control circuit 13 continues the alarm sound until the power is not supplied. In this case, since the setting of the power shut-off mode is restricted in step 404, even if the power key 23 is operated when the power is turned on, the alarm sound continues until the power is not supplied. Here, “continue until no power is supplied” means, for example, that the sounding continues until the remaining amount of the battery 25 shown in FIG. Is removed or the power supply is cut off due to unauthorized operation.

  If step 422 is affirmative, that is, if the input of the password number data is a predetermined number of times or more, the process proceeds to step 426, and the main control circuit 13 continues the alarm sound until the power is not supplied. Then, when the process of step 426 ends, the process of this flowchart ends.

(Power-on mode)
Returning to FIG. 4, if step 300 is affirmative, that is, if warning setting data is registered, the main control circuit 13 performs processing in the power-on mode shown in FIG. 6 in step 301. Hereinafter, the processing in the power-on mode will be described with reference to FIG. In addition, when the power is turned on in the power-on mode, that is, the warning mode is not released (warning mode), only the password data input screen is displayed (becomes “standby mode”). It is set in advance.

  In the power-on mode, it is set in advance so that all other functions such as the power-off mode and the call mode are restricted. Furthermore, in this embodiment, in order to make it easier to detect unauthorized possession of the stolen mobile phone 10A, the alarm sound may be continued until the power is not supplied even in the standby mode (FIG. 5). Step 426 shown).

  In FIG. 6, in step 500, the main control circuit 13 (see FIG. 2) of the mobile phone 10A determines whether or not personal identification number data has been input. If step 500 is affirmative, that is, if password data is input, in step 502, the main control circuit 13 reads the set password data from the memory 26 shown in FIG.

  In step 504, the main control circuit 13 determines whether or not the password number data input by the input device 22 matches the set password number data recorded in advance in the memory 26. If step 504 is affirmative, that is, if the code number data matches the set code number data, the main control circuit 13 deletes (changes) the “warning setting (data)” registered in the memory 26 in step 506. . For example, in this case, the “warning setting” flag set in step 404 (see FIG. 5) is defeated and the flag is set to “0”.

  In step 508, the main control circuit 13 releases restrictions on other functions including the power-off mode. Specifically, in step 508, when the power key 23 is operated when the power is turned on, for example, the power-off mode is set, and a call or mail can be transmitted / received to / from another terminal. When the process of step 508 is completed, the process proceeds to step 302 shown in FIG. 4 (see arrow “A”) and waits for an incoming call.

  If step 504 is negative, that is, if the password data does not match the set password data, in step 510, the main control circuit 13 determines whether there is another password data input. If step 510 is affirmative, that is, if the password data is input again, the process returns to step 504, and the main control circuit 13 determines whether or not the password data again matches the set password data. If step 510 is negative, that is, if the password data is not input again, the processing of this flowchart ends. That is, in the present embodiment, as long as the password data does not match the set password data, other functions are held in an invalid state, and use of the stolen mobile phone 10A is restricted.

  In the present embodiment, the same applies even when the user of the mobile phone 10A simply leaves the mobile phone 10A. Further, in the cellular phone 10A of this embodiment, the biometric authentication circuit 20 shown in FIG. 2 may use authentication such as a fingerprint or an existing SIM number (password) to confirm the identity. The identity verification process is performed, for example, during the process of step 412 shown in FIG.

  In the present embodiment, for example, a non-contact operation such as ringing of a ring tone or vibration is performed so that a person who has illegally possessed the cellular phone 10A that has been stolen (unauthorized owner) cannot recognize it. The IC function is stopped (see step 402 in FIG. 5), and a loud alarm is sounded (see step 406 in FIG. 5) in a state where the setting of the power-off mode is restricted (see step 404 in FIG. 5). According to the present embodiment, since the warning mode is set without performing the incoming call operation, unauthorized use of the mobile phone 10A is regulated in advance and reliably. In addition, according to the present embodiment, since the suspension of the alarm function by an unauthorized owner of the mobile phone 10A is restricted, it is easy to find the unauthorized possession of the mobile phone 10A, and the illegal use of the mobile phone 10A is surely prevented. To do.

  In the present embodiment, when the lost mobile phone 10A is set to the warning mode, the special number data is added to the caller ID data by using a conventionally used DTMF signal (message data) or the like. , Existing infrastructure can be used effectively. Therefore, according to the present embodiment, since the warning mode can be set by effectively using the existing infrastructure, it is possible to suppress an increase in cost due to the infrastructure change.

  Further, in the present embodiment, the non-contact IC function of the lost mobile phone 10A can be stopped by communication (contact) from an unspecified contact terminal (such as 10B or 40). For example, electronic money transactions such as purchasing electronic tickets can be prevented. In the present embodiment, the contact terminal for setting the warning mode is not limited, so that the contactless IC function can be quickly stopped without being restricted by the current location or environment of the user.

  Furthermore, in this embodiment, terminal identification data from an unspecified contact terminal is collated with the terminal information stored in the database 36 (see FIG. 1), so that the warning mode can be surely set and the user can achieve it. It can prevent the case of slushing. According to the present embodiment, if the mobile phone 10A is lost due to misplacement or the like, a high volume alarm sounds by setting a warning mode, so that the lost mobile phone 10A can be easily found. .

  As a modified example of the present embodiment, as alarm sound for warning, voice data (message sound) such as “lost” or “stolen” may be repeatedly output in addition to the alarm sound. The management server 28 shown in FIG. 1 obtains terminal information (see the management table 37 shown in FIG. 3) associated with the telephone number in addition to the owner identification information from the database 36. For example, the position data of the lost mobile phone 10A can be acquired by utilizing the position information included in the terminal information. In this case, if report data including the position information is transmitted from the management server 28 to a terminal of an organization such as the police or a security company, it can be used for crime control.

  The flow of processing of each program described in the above embodiment (see FIGS. 4 to 6) is an example, and can be changed as appropriate without departing from the gist of the present invention. Moreover, in the said embodiment, although a mobile radio | wireless terminal is an example as the mobile telephone 10, the mobile radio | wireless terminal of this invention is a concept including PDAs (PERSONAL Digital Assistants), a personal computer, etc. which are a radio | wireless type and are equipped with a telephone function. is there.
