JP4462545B2 - Mobile phone terminal with contactless IC card function and operation method thereof - Google Patents

Description

  The present invention relates to a mobile phone terminal having a non-contact IC card function and an operation method thereof.

  A mobile phone terminal can be carried in a pocket or bag, and it can be called at a desired location at any time as long as radio waves from the base station can reach. .

  In recent mobile phone terminals, a model having a mail browser function in addition to a call function has become mainstream, and a model having a function such as a GPS function has become widespread. Recently, mobile phone terminals with a contactless IC card function have also been released.

  Since the functions of the non-contact IC card include card functions such as electronic money and commuter passes, security problems at the time of theft or loss of the mounted mobile phone terminal are becoming important. A mobile phone terminal equipped with a non-contact IC card function receives a certain number of calls from a specific phone to the mobile phone terminal within a predetermined time so that it cannot be used by anyone other than the owner in case of theft or loss. Products that are equipped with a lock function that makes it impossible to remotely use the terminal by putting on the phone have been put on the market.

In Patent Document 1, in a portable terminal having a non-contact IC card function, a personal identification number is registered in the portable terminal in order to prevent unauthorized use by others at the time of loss or theft. A technique is disclosed in which an input of a personal identification number is requested prior to use of the password, and the unusable state is canceled for a predetermined time only when the input personal identification number matches a registered personal identification number.
Japanese Patent Laid-Open No. 2003-16398

  Although the above-described lock function can prevent telephone calls, communication, and terminal operations, the non-contact IC card function such as electronic money and commuter pass is available even when the terminal is locked.

  As described above, by requiring the input of a personal identification number for use of the non-contact IC card function, unauthorized use of the non-contact IC card function by a person other than the terminal owner can be prevented. However, such a personal identification number function is not necessarily attached to all terminals, and even if such a personal identification number is attached, use of the personal identification number is complicated and security is not perfect.

  Therefore, when a mobile phone terminal having a non-contact IC card function is lost or stolen, not only without a PIN code function but also with a PIN code function, the non-contact IC card function can be detected by leaking or detecting the PIN code. May be used illegally by others. In such a case, it is preferable if the person can recognize that the contactless IC card function of the mobile phone terminal has been used illegally. Further, it is more preferable if the location of the terminal can be recognized.

  The present invention has been made in such a background, and the purpose of the present invention is to use the non-contact IC card function by a person other than the terminal owner when the mobile phone terminal with the non-contact IC card function is lost. It is an object of the present invention to provide a mobile phone terminal and a method of operating the same that enable the terminal owner to recognize the location of the terminal.

  A mobile phone terminal with a non-contact IC card function according to the present invention is a non-contact IC card function unit that realizes a non-contact IC card function, a position information acquisition unit that acquires position information of the terminal itself, and an instruction from the outside Lock means for disabling the operation of the terminal itself, communication means for communicating with the base station, and the position information acquisition means at a predetermined timing after the lock means is locked. And control means for acquiring and notifying position information to a predetermined notification destination by the communication means.

When the owner of a mobile phone terminal that has been lost or stolen makes an instruction to the terminal from the outside and disables the operation of the terminal, the terminal subsequently acquires the location information of the terminal at a predetermined timing. Is notified to a predetermined notification destination.

  When the predetermined timing is set at predetermined time intervals, whether the terminal position is changed or not, it is fixed by whether the terminal is moving over the hand of the finder, etc. You can see if it is in position. In addition, a first fixed time and a second fixed time shorter than this are set, and notification is given every first fixed time until the use of the non-contact IC card in the locked state is confirmed. After the use of the non-contact IC card is confirmed, notification may be performed by switching the “certain time” to the second certain time. As a result, until the use of the non-contact IC card function, the position is notified in a long time unit to reduce battery consumption, and after the use, the position is notified in a short time unit, and the movement route of the terminal is determined. It can be tracked finely.

  When the predetermined timing is when the use of the non-contact IC card function is detected, the fact that the non-contact IC card function is used by a person other than the owner of the terminal and the use location thereof are recognized. can do.

  The notification preferably includes date and time information at the time of acquisition of position information in addition to the position information. As a result, not only the position information but also when the position was reached can be known.

  In the case where the predetermined timing is both at predetermined time intervals and when the use of the non-contact IC card function is detected, a notification destination when using the non-contact IC card function is set to a predetermined time. It can be different from the notification destination at the time of each notification. That is, unlike the case of notification at regular intervals, the use of the non-contact IC card function has a high probability of being illegally performed, so that it is possible to cope with notification to a crime prevention organization or the like.

  In the case where a message is included in the notification of the position information, the predetermined timing includes both the predetermined time interval and when the use of the non-contact IC card function is detected. It is preferable that the message at the time of using the card function is different from the message at the time of notification every predetermined time. This is to notify the notified person of the cause of the notification.

  The operation method of the mobile phone terminal with a non-contact IC card function according to the present invention includes a step of disabling the operation of the own terminal according to an instruction from the outside, and an automatic operation at a predetermined timing after disabling the operation of the own terminal. The method includes a step of acquiring position information of the terminal, and a step of notifying the acquired position information to a predetermined notification destination. With this operation method, the mobile phone terminal confirms the position of its own terminal at a predetermined timing after the operation of its own terminal is disabled in response to an instruction from the outside, and notifies the predetermined notification. You will be notified first.

  According to the present invention, when a mobile phone terminal is lost or stolen, the terminal is remotely locked to automatically notify the position information of the terminal to a predetermined notification destination at a predetermined timing. be able to. Therefore, the terminal owner can recognize the position of the terminal.

  In addition, it is possible to track the movement route of the person who finds the terminal by periodically notifying the position information.

  When the contactless IC card function is used, the location information is notified together with the fact that the other person can recognize that the contactless IC card function of the terminal is used and the place where the terminal is used.

  As mobile phone terminals having such a notification function of the present invention become widespread, an effect of preventing unauthorized use of the non-contact IC card function by a terminal finder or the like is expected.

  Hereinafter, the operation in the present embodiment will be described.

  FIG. 4 is an explanatory diagram of notification setting items related to position information notification in the present embodiment. Notification setting items include a notification method, a notification destination, notification contents, and notification timing.

  The “notification method” may be a telephone call, an e-mail, or a short message. In the case of a telephone call, a voice call or DTMF signal can be used. In any case, the terminal automatically sends a call, an e-mail, or a short message regardless of the user's operation.

  The “notification destination” may be an individual (owner of the terminal itself or a family member), a communication carrier, the above-described crime prevention organization, or the like. As information for specifying a specific notification destination, a telephone number is used in the case of a telephone and a short message, and an electronic mail address is used in the case of an electronic mail.

  “Notification content” is a voice message prepared and recorded (or stored) in the case of voice by telephone. In the case of DTMF, a DTMF signal corresponding to a predetermined key combination is transmitted. In the case of an e-mail or a short message, it is a text message prepared and stored in advance. This text message can include terminal location information and / or date / time information when using or notifying the contactless IC card function.

  In the notification destination, the phone number is recognized as the caller notification information in the case of a call, and the caller's e-mail address is recognized in the case of an e-mail. (For example, the address and name of the terminal owner) may be included in the message.

  The “notification timing” may be after a certain time and / or when using the non-contact IC card function. The fixed time may be a predetermined fixed time, but may be variably set by the user.

  These setting items are preferably selected by the user according to the initial settings and stored in the mobile phone terminal.

  FIG. 5 is a flowchart showing processing of control unit 210 when the non-contact IC card function of the mobile phone terminal according to the present embodiment is used. This process is executed when the use of the non-contact IC card function is detected. The control unit 210 (FIG. 3) can recognize the use of the non-contact IC card function by a notification (for example, an interrupt) from the non-contact IC card function unit 702.

  First, it is checked whether or not the lock mode is set (S11). When the terminal is locked remotely as described above, there is a high probability of use by a person other than the terminal owner when the use of the non-contact IC card function is detected. Therefore, the current position is confirmed by the GPS function unit 602 (FIG. 3) (S12), and the contents of the notification setting as described in FIG. 4 are confirmed (S13). Next, the notification method according to the notification setting notifies the notification destination of the location information along with a predetermined message (S14).

  FIG. 6 is a flowchart showing processing of control unit 210 when the mobile phone terminal is locked (in a locked state) in the present embodiment.

  When the lock state is established, first, the notification setting is confirmed (S21). If it is set to notify at regular intervals (S22, Yes), it is checked whether or not the regular time has arrived (S24). It is considered that the certain time is preferably about 10 minutes to several hours, for example. When a certain time has arrived, the location of the terminal is confirmed (S25), and location information is notified together with a predetermined message to the notification destination by a notification method according to the notification setting (S26). If the predetermined time has not come in step S24, the process proceeds to step S23 described later.

  The notification destination in step S26 may be dynamically changed under a predetermined condition. For example, the notification destination can be made different between a notification at regular intervals and a notification by using a non-contact IC card function. More specifically, notification is made only to an individual at regular intervals, and notification is made to an individual and a crime prevention organization (or a telecommunications carrier, etc.) using a contactless IC card function. In addition, it is preferable that the notification message is also changed between notification at regular time intervals and notification using the non-contact IC card function. For example, in the former case, “This year, month, day, day, hour, and minute, this terminal is in North latitude and longitude.” In the latter case, “Year, month, day, hour, minute, north latitude, A message such as “The IC card has been used” can be considered.

  When the notification for every fixed time is not set in step S22 (S22, No), it is checked whether or not the non-contact IC card function has been used (S23). Use of the non-contact IC card function can be confirmed by storing flag information in the memory unit 212, for example. That is, when the non-contact IC card function is used, the flag is turned on, and the flag is turned off after confirmation.

  Steps S22 to S26 are repeatedly executed until the lock is released (S27). When the lock is released, the processing in FIG. 6 is terminated.

  As a modified example of the operation, when “notify every fixed time” is set, the first fixed time and the second fixed time shorter than this are set, and the use of the non-contact IC card in the locked state is confirmed. Notification is made every first fixed time until it is done, and after confirming the use of the non-contact IC card in the locked state, the notification is performed by switching “fixed time” to the second fixed time. Also good. The GPS function unit is supplied with power only when the position is confirmed. Thereby, after the use of the non-contact IC card is confirmed, the position tracking in a short time unit can be performed while suppressing the power consumption of the battery of the GPS function unit.

  FIG. 7 is a diagram for explaining an operation example when using the notified position information. Here, two modes of FIG. 7A and FIG. 7B are shown.

  In the mode of FIG. 7A, the location information is notified from the mobile phone terminal with a non-contact IC card function to the notification destination terminal (S31). In response to the user's instruction, the notification destination terminal makes a “map request” for requesting a reply of map information to the server of the service provider using this position information (S32). In response to this request, the server generates map information in which the notification position is marked on the map around the position of the position information (notification position) (S33), and transmits this to the notification destination terminal (S34). The notification destination terminal receives this map information and displays it on the display unit (S35).

  The map request can be made by the user accessing the service provider's web server using, for example, the http protocol. At this time, the user needs to input the notified position information. Alternatively, a map request can be made by e-mail. This e-mail includes position information together with a map request command, and is preferably automatically created according to a user instruction. The map request command can be realized by including a predetermined keyword in any of the header part, the subject part, and the body of the electronic mail. When a map request is made by e-mail, the reply information may be returned with the map information attached, or the URL is described in the reply mail and the user accesses the URL and the target map is displayed on the web site. May be viewed.

  In the mode of FIG. 7B, the location information is notified to the server from the mobile phone terminal with a non-contact IC card function (S41). This location information notification includes the return information of the map information. However, if the user registration for using this service has been performed in advance for the service provider, the reply destination information is registered at the time of notification (S41) by registering the reply destination information at the time of the user registration. Need not be included. Upon receiving this notification, the server generates map information in which the notification position is marked on the surrounding map of the position (notification position) of the position information (S42), and transmits this to the reply destination terminal (S43). The reply destination terminal that has received the map information displays it on the display unit (S44). It should be noted that notification to the “reply-to” terminal may be performed together with the notification from the mobile phone terminal to the server.

  According to the present embodiment, when a mobile phone terminal with a non-contact IC card function is lost or stolen, the mobile phone terminal is automatically set on the condition that the terminal is remotely locked. The position can be confirmed and the position information can be notified to a predetermined notification destination. This makes it possible to recognize the location of the mobile phone terminal, the use of the non-contact IC card function, and the usage location. In addition, the whereabouts of the terminal can be traced by periodically checking the position of the terminal.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, when the location information is notified, the server is used each time to use the map information, but the location information is received from a non-portable terminal such as a personal computer or a security organization terminal. It is also possible to hold map information locally on the terminal side and display map information without using a server each time.

  In addition, although the location information is acquired using GPS, the location information acquisition means of the present invention is not limited to GPS, and any other location information acquisition means can be used.

  The “every fixed time” notification may be a notification at a regular time such as a predetermined time of the day.
