Thereafter, the result of the data deletion operation (that is, the success or failure of complete deletion) is transmitted to the center apparatus 20 via the network 100 (sequence A10).

  The center device 20 that has received the execution result of the deletion operation displays the execution result to the call center operator, and the call center operator sends the execution result of the data deletion operation to the mobile phone 11 of the user 1 by the call center telephone 21. Notification is made (sequence A11).

  In the description of FIGS. 1 and 2 above, when the notebook PC 10 owned by the user 1 and the mobile phone 11 are reversed, the mobile phone 11 is separated from the user 1 by a predetermined distance or more. Can be handled in exactly the same way.

  In this case, the call center operator who has displayed that the distance between the notebook PC 10 and the mobile phone 11 is a predetermined distance or more is displayed on the notebook PC 10 at hand of the user 1 instead of the mobile phone 11. This is notified not only by voice but also by means such as mail or instant messenger.

  The user 1 who has received this notification by the notebook PC 10 has a conversation with the call center operator by means of voice, e-mail, instant messenger or the like using the notebook PC 10 and records the data (phone number or mail address) Or delete data such as sent / received mail).

  The call center operator who has received such a deletion instruction operates the center device 20 to send a data deletion command signal to the mobile phone 11 via the network 100 or further via the telephone communication network 200. The data is transmitted and the data of the mobile phone 11 is deleted.

  As described above, in the mobile terminal monitoring system of the present invention, it is possible to always monitor any mobile terminal of the notebook PC 10 or the mobile phone 11, but the mobile terminal monitoring center determines which one is monitored. The user 1 is registered in advance in the center device 20 of 2A.

  Alternatively, in some cases, the center device 20 detects that the physical distance between the mobile terminals owned by the user 1 is more than a predetermined distance without registering the monitoring target mobile terminals in advance. In such a case, the call center operator transmits a message to that effect to both mobile terminals at remote locations, and when one of the mobile terminals responds, the call center operator stores the data of any mobile terminal among the mobile terminals at remote locations. Whether to delete or not may be determined by talking with the user 1.

  Furthermore, in order to ensure safety when executing such a deletion instruction, a mechanism using a password registered in advance may be prepared.

(Explanation of effect by Example 1)
As described above, according to the first embodiment of the mobile terminal monitoring system of the present invention, if the user always carries one of the mobile terminals owned by the user, the other mobile If the physical distance from the terminal is increased, the call center operator of the mobile terminal monitoring center 2A automatically receives a notice to that effect and prompts attention.

  This eliminates the need for the user to constantly monitor the location of the notebook PC 10 or the mobile phone 11 that the user owns until receiving a contact from the call center operator, thereby greatly reducing the burden on the user. Further, when the mobile phone 11 and the notebook PC 10 are separated from each other, the user 1 can immediately know the possibility of the notebook PC 10 or the mobile phone 11 being stolen or lost by receiving a notification immediately from the call center operator. It can also prevent theft and loss.

  Even if the data on the notebook PC 10 or the mobile phone 11 may be leaked to a third party due to theft or loss, the mobile terminal monitoring center 2A can The data itself on the notebook PC 10 or the mobile phone 11 can be deleted by remote operation of the call center operator, and information leakage can be prevented.

(Other embodiments of the invention)
Next, different embodiments of the mobile terminal monitoring system according to the present invention will be described.
As the mobile terminal monitoring system in the first embodiment described above, instead of the user 1, the mobile terminal monitoring center 2A (or its call center operator) constantly monitors the location of the mobile terminal to be monitored, for example, the notebook PC 10 and needs it. Accordingly, a case has been described in which the data stored on the notebook PC 10 is deleted before the data is leaked to a third party. However, the present invention is not limited to such a case.

  For example, all processes executed by the mobile terminal monitoring center 2A are installed in a mobile terminal that the user 1 always carries, such as a mobile phone 11, or the current location of each of a plurality of mobile terminals owned by the user 1 is determined. The position information shown is always received, and based on the position information, the distance to the mobile terminal that the user 1 always carries is calculated, and it is detected that the calculated distance is a predetermined distance or more. In this case, a signal transmission means for transmitting a deletion command signal for instructing deletion of data to the mobile terminal separated by a certain distance or more is always carried automatically or in response to an instruction from the user 1 of the mobile terminal. A mobile terminal such as the mobile phone 11 may be provided at least.

  By adopting such a configuration, a plurality of mobile terminals owned by the user 1 can be obtained only by the mobile terminal 11 that the user 1 always carries without using the mobile terminal monitoring center 2A, for example, the mobile phone 11 alone. It is possible to adopt a mechanism for automatically managing

  In addition, the mobile terminal monitoring center 2A side and the notebook PC 10 and the mobile phone 11 on the mobile terminal side respectively execute the above-described monitoring operation and data deletion operation of the mobile terminal by program logic, and the mobile terminal monitoring center. 2A and a mobile terminal monitoring program that operates on each of the notebook PC 10 and the mobile phone 11 of the mobile terminal, and can also be sold as a program recording medium using the mobile terminal monitoring program as package software. Is possible.

  Furthermore, when the program is logicized as described above, the program on the mobile terminal monitoring center 2A side is incorporated into a mobile terminal that is always carried by the user 1, for example, the mobile phone 11, so that the call center operator of the mobile terminal monitoring center 2A Even if the mobile terminal monitoring center 2A itself does not exist, the user 1 himself / herself automatically manages a plurality of mobile terminals owned by the user 1 only by the mobile terminal that the user 1 always carries, for example, the mobile phone 11. It is possible to have a mechanism like this.

  Further, by directly programming what the call center operator of the mobile terminal monitoring center 2A performs, it is possible to automate the work contents of the call center operator of the mobile terminal monitoring center 2A and eliminate the need for an operator. In this case, for example, the conversation from the call center operator to the user 1 is replaced by automatic voice guidance for the user 1 including selection items for selecting the response and instruction of the user 1, while the conversation from the user 1 to the call center operator is performed. These responses and instructions may be replaced by selecting from the selection items from the mobile terminal monitoring center 2A by push button input to the mobile phone 11 or by voice.

  In addition, the operation details (instructions and responses) of the call center operator and the user 1 can be fully automated by programming and registering in advance for all cases. For example, the notebook PC 10 is set in advance such as midnight. If the user moves to a position that is more than a predetermined distance from the hand of the user 1 during this time period, it is assumed that there is a high possibility of theft, and the warning information to that effect is automatically notified immediately. An instruction to automatically delete the data of the notebook PC 10 may be given as there is a risk of leakage.

  Furthermore, when the program on the mobile terminal monitoring center 2A side is incorporated into a mobile terminal that the user 1 always carries, for example, the mobile phone 11, the user 1 can perform a simple interactive selection operation as described above. It is also possible to automatically manage its own mobile terminal. Further, even if the user 1 does not contact the call center operator of the mobile terminal monitoring center 2A that the mobile terminal, for example, the notebook PC 10 is more than a predetermined distance from the hand, the user PC 1 can be stolen or lost. Of course, when the user 1 himself / herself recognizes that it is highly likely, the data on the notebook PC 10 can be deleted.

  In this case, when it is intended to instruct the deletion of data by the user 1's own recognition, it can be realized by performing the operations after the sequence A7 shown in FIG. The call center operator of the mobile terminal monitoring center 2A that has received the deletion instruction from the user 1 who owns the notebook PC 10 operates the center device 20 to extract the destination of the notebook PC 10, and remotely operates the notebook PC 10 on the notebook PC 10. An instruction to send a deletion command signal for deleting data from the center device 20 to the notebook PC 10 is issued.

In addition to the center 2A, the information management server 22 is connected to the network 100, and can transmit and receive data to and from the center device 20 or from a large number of users' mobile terminals. A large amount of data for a large number of users, that is, information on a plurality of mobile terminals owned by each user is collectively managed.

  In addition to the center device 20 in FIG. 1, the information management server 22 receives and updates and registers the position information constantly notified from each of the plurality of mobile terminals of each user, and based on the received position information. And calculating the distance between each user's plurality of mobile terminals and the mobile terminal that the user always carries, and detecting that the calculated distance is more than a predetermined distance, Warning information indicating that fact is notified to the mobile terminal and the center device 20 that the user always carries.

  Further, the information management server 22 receives a deletion instruction from the call center operator of the center device 20 from the center device 20 and is separated from the user's hand by a predetermined distance or more in place of the center device 20 in FIG. A deletion command signal for instructing deletion of data is transmitted to the mobile terminal via the network 100.

  On the other hand, the center device 20 receives information provided from the information management server 22 that collectively manages a large amount of data via the network 100 and notifies the call center operator while receiving input from the call center operator. The data can be sent to the information management server 22 via the network 100 and stored in the information management server 22 for batch processing.

  FIG. 3 shows a case where the center device 20 and the information management server 22 are connected via the network 100. However, if the two are located close to each other, The center device 20 and the information management server 22 may be directly connected.

Next, with reference to FIG. 3 and FIG. 4, different examples of the operation of the mobile terminal monitoring system according to the present invention will be described in more detail by taking as an example the case where the notebook PC 10 has moved away from the user 1.

  FIG. 4 is a sequence chart for explaining a different example of the operation of the mobile terminal monitoring system according to the present invention. In this case, the mobile terminal monitoring center 2B further provided with the information management server 22 is used as shown in FIG. FIG. 4 shows the operation of the mobile terminal monitoring system when the notebook PC 10 has moved away from the user 1. In the following, the difference from the first embodiment will be mainly described while comparing with the sequence diagram of the first embodiment shown in FIG.

  In FIG. 4, the position information of the notebook PC 10 and the mobile phone 11 transmitted in the sequences A1 and A2 in FIG. 2 is transmitted to the information management server 22 instead of the center device 20, and the information management server 22 Collectively managed (sequences B1 and B2). Further, the display contents displayed to the call center operator in the sequences A3 and A4 in FIG. 2 are also transmitted to the center apparatus 20 from the information management server 2 that collectively manages information in FIG. (Sequence B3) is displayed from the center apparatus 20 to the call center operator (sequences B4 and B5).

  That is, the information management server 22 calculates the physical distance between the notebook PC 10 and the mobile phone 11 based on the received location information of the notebook PC 10 and the location information of the mobile phone 11, and calculates the calculated physical If it is found that the distance is greater than a predetermined distance, that is, a predetermined distance from the user, the name of the corresponding user 1 is notified to the center device 20 at the same time. Then, information about the user 1 such as the telephone number of the mobile phone 11 and the terminal number and destination for specifying the notebook PC 10 is transferred to the center device 20 (sequence B3).

  The center device 20 that has received a notification from the information management server 22 that the physical distance is greater than a predetermined fixed distance, that is, a predetermined distance from the user, operates the center device 20. This is displayed to the call center operator who is present (sequence B4). At the same time, information about the user 1 such as the name of the corresponding user 1, the telephone number of the mobile phone 11, the terminal number for specifying the notebook PC 10 and the destination is displayed to the call center operator (sequence B5).

  Thereafter, the operations of the sequences B6 to B8 in FIG. 4 are exactly the same as the operations of the sequences A5 to A7 in FIG. 2, and first, based on the displayed information, the call center operator carries the mobile 1 that the user 1 always carries. When the telephone 1 is notified as warning information that the physical distance between the notebook PC 10 and the mobile phone 11 is more than a predetermined distance (sequence B6), the user 1 has his own notebook PC 10 Is reconfirmed (sequence B7).

  Next, the fact that the physical distance between the notebook PC 10 and the mobile phone 11 is more than a predetermined distance has occurred due to factors that the user 1 is not aware of, such as theft or loss. If the user 1 determines that the data stored on the notebook PC 10 needs to be deleted, the user 1 causes the call center operator to delete the data on the notebook PC 10. Instruction is given (sequence B8).

  The call center operator receiving the data deletion instruction on the notebook PC 10 inputs to the center device 20 to send the deletion instruction received from the user 1 to the information management server 22, unlike the case of FIG. (Sequence B9). In response to the input of the transmission instruction from the call center operator, data indicating the deletion instruction from the user 1 is transmitted from the center device 20 to the information management server 22.

  The information management server 22 that has received the data indicating the deletion instruction from the user 1 uses the destination of the notebook PC 10 instead of the center device 20 in FIG. A deletion command signal for instructing deletion of data on the notebook PC 10 is transmitted to the notebook PC 10 (sequence B10).

  The notebook PC 10 that has received the deletion command signal from the information management server 22 completely deletes the data stored in the notebook PC 10 itself based on the deletion command signal as in the sequence A9 in FIG. 2 (sequence B11). . Thereafter, the result of the data deletion operation (that is, the success or failure of the complete deletion) is different from the sequence A10 in FIG. 2, and the information management that has transmitted the deletion command signal instead of the center device 20 in FIG. It transmits to the server 22 (sequence B12).

  The information management server 22 that has received the execution result of the deletion operation transmits the execution result to the center device 20 (sequence B13) and displays it to the call center operator. The call center operator uses the call center telephone 21 to The result of data deletion is notified to the mobile phone 11 of the user 1 (sequence B14).

  By the operation of the information management server 22 as described above, the processing load of the center device 20 that manages the dialogue processing with the call center operator of the mobile terminal monitoring center 2B can be greatly reduced, and it is possible to deal with a large number of users.

  First, the notebook PC 10 owned by the user 1 constantly transmits position information indicating the current location, not to the center apparatus 20 but to the mobile phone 11A, unlike the sequence A1 of FIG. (Sequence C1). On the other hand, in the mobile phone 11A owned by the user, the position information indicating the current location is different from the sequence A2 in FIG. Will not send.

  Furthermore, in the mobile phone 11A, the physical communication between the notebook PC 10 and the mobile phone 11A is based on the received location information of the notebook PC 10 and the location information of the mobile phone 11A stored in the mobile phone 11A. The ideal distance. If it is found that the calculated physical distance is more than a predetermined distance set in advance, that is, a predetermined threshold distance from the user, unlike the sequence A3 in FIG. Instead of transmitting to the device 20, the fact is displayed to the user 1 carrying the mobile phone 11A (sequence C3).

  Unlike the sequences A4 and A5 in FIG. 2 of the first embodiment, the process of displaying information related to the user 1 such as the name of the user 1 and the telephone number of the mobile phone 11 to the call center operator, and the notebook PC 10 from the call center operator is constant. There is no need to make a telephone contact that the user is more than a distance away.

  The user 1 who has obtained an indication that the notebook PC 10 is separated by a certain distance or more reconfirms the location of the notebook PC 10 that he / she owns (sequence C4), as in the sequence A6 of FIG.

  The fact that the physical distance between the notebook PC 10 and the mobile phone 11A is more than a predetermined distance is caused by a factor that the user 1 is not aware of, such as theft or loss. Unlike the sequence A7 of FIG. 2 in the first embodiment, when the user 1 determines that the data stored on the notebook PC 10 needs to be deleted, it is not for the call center operator. The user 1 instructs the mobile phone 11A itself to delete the data on the notebook PC 10 (sequence C5).
