Description

  The present invention relates to wireless communication, and more particularly, to a method, a program, and a system for performing control such as locking of a mobile terminal using an existing wireless communication network.

  Since mobile terminals such as PHS terminals, mobile phones, and notebook personal computers (PCs) are easy to carry, it may be necessary to remotely control the operations of these mobile terminals in an emergency. For example, these mobile terminals usually store highly confidential data such as personal information such as a telephone directory and an address book and internal information of a company where the user works. For this reason, when the user loses the mobile terminal, it is required to lock the mobile terminal promptly in order to prevent browsing or unauthorized use of these data by a third party who has picked up the mobile terminal. Is done. Here, locking the mobile terminal means, for example, prohibiting a call operation or an incoming call operation, prohibiting reading of data stored in a memory in the mobile terminal, or various operation buttons provided in the mobile terminal. This includes the prohibition of the use of all or part of the input / output functions of the mobile terminal, including prohibiting the operation of the mobile terminal.

  As a solution to meet such demands, conventionally, the receiving subaddress data for locking the wireless communication terminal is stored in advance in the memory in the wireless communication terminal, and when the wireless communication terminal is lost, it is used for lock state control. There has been proposed a technique for locking a wireless communication terminal by making a call to the wireless communication terminal using a telephone number to which a destination subaddress is added (for example, Patent Document 1).

  In addition, for example, a technique for preventing information leakage at the time of loss by using a hardware key corresponding to a USB interface and preventing operation of the mobile terminal unless the key is inserted into the mobile terminal. Has also been proposed and put to practical use.

  In addition, when a dial-up connection from a wireless communication terminal such as a wireless communication card or PHS communication module connected to a notebook PC to an authentication server or the like arranged on the wireless network cannot be performed normally, There has already been proposed a system for remotely locking a PC by determining that the person currently operating the PC is not a legitimate user and transmitting a specific signal from the authentication server to the wireless communication terminal via the wireless network. It has reached practical use.

Further, in response to a declaration of loss from the user of the notebook PC and the wireless communication terminal used connected thereto, the wireless communication terminal and the PC are registered as remote lock target terminal devices in the central office database. In addition, when dial-up connection is performed by a wireless communication terminal, there is a system in which the wireless terminal or PC is recognized as a remote lock target terminal device and a specific signal is transmitted from the central office to remotely lock the wireless communication terminal or PC. It has been proposed (for example, Patent Document 2).
JP-A-6-326659 Japanese Patent Application No. 2005-92893

  However, the above-described conventional technology does not sufficiently realize control of a mobile terminal required in an emergency. For example, in order to realize the technique described in Patent Document 1, when a user makes a call to a wireless communication terminal, the wireless communication terminal to be locked is in a state where the wireless communication service is turned on. Must be in the vicinity. Therefore, when the PHS terminal or mobile phone is lost with the power turned off, or when the wireless communication terminal such as a PHS communication card is inserted into the PC with the power turned off, these mobile terminals and Until a third party who has picked up the wireless communication terminal turns on the power in the wireless communication service area, the terminal device may not be locked. In addition, in order to provide such a service, it is necessary to newly install a dedicated server or the like on the wireless communication network.

  Further, regarding the solution using the hardware key, the user needs to purchase the key anew. In addition, it is considered that there are many situations in which the mobile terminal is lost while the key is inserted. In such a case, unauthorized use of the mobile terminal by a third party cannot be avoided.

  As for the technology for locking the mobile terminal when the dial-up connection fails, radio traffic is generated every time the dial-up connection for confirming whether or not the mobile terminal should be locked. May be used in vain. In addition, each time a dial-up connection is attempted, a telephone fee is generated, increasing the burden on the user. The technique of Patent Document 2 has a similar problem.

  In addition to the purpose of locking the mobile terminal, in addition to providing information to the user automatically and quickly via a wireless communication terminal in the event of an emergency such as a disaster, or the security installed on the software installed on the mobile terminal There is also a social demand for technology that enables remote operation of a mobile terminal in a broader sense, such as automatically performing a version upgrade when a certain defect is found. A method and system that can satisfy such high requirements and solve the above-described problems of the prior art have not been proposed so far. The present invention can realize such a method and system and provide a more complete wireless communication service.

  A second aspect of the present invention is a mobile terminal, a wireless communication terminal used by being connected to the mobile terminal and having storage means, and a center having information indicating whether or not the mobile terminal should perform a predetermined operation The wireless communication terminal makes a location registration authentication request to the central station via the wireless base station, and when the central station has succeeded in location registration authentication, A message including the information in a predetermined part of the format is transmitted to the radio base station, and after the location registration is completed, the radio base station wirelessly communicates a message including the information in a predetermined part of the data format indicating that Requesting the mobile communication terminal to notify the wireless communication terminal of the status of the information in a wireless communication network in which the wireless communication terminal stores the information in the storage means. Serial information is a program for executing and performing the predetermined operation to indicate that it should perform a predetermined operation.

  The third aspect of the present invention provides a mobile terminal, a wireless communication terminal that is used by being connected to the mobile terminal and includes storage means, and information indicating whether the mobile terminal should perform a predetermined operation. A wireless communication system comprising a central station and a wireless base station, wherein the wireless communication terminal makes a location registration authentication request to the central station via the wireless base station, and the location registration authentication is successful. The central station transmits a message including the information in a predetermined part of the data format indicating that to the wireless base station, and after the location registration is completed, the wireless base station adds to the predetermined part of the data format indicating that. A message including the information is transmitted to a wireless communication terminal, the wireless communication terminal stores the information in a storage unit, and in response to a request from the mobile terminal, the wireless communication terminal notifies the mobile terminal of the state of the information, The information To indicate that it should perform a predetermined operation, configured mobile terminal performs the predetermined operation.

  According to the first to third aspects of the present invention, when the wireless communication terminal is turned on, when the wireless communication terminal moves to a different service area at predetermined time intervals, and from the mobile terminal to the wireless communication terminal, You may comprise so that a location registration request may be performed at least at the time of a command being issued.

  The mobile terminal may be locked when the information indicates that the mobile terminal should be locked. In this case, the mobile terminal may be further locked when the information stored in the storage means has not been updated for a predetermined period.

  Further, when the information indicates that disaster information should be provided, the mobile terminal may be configured to provide disaster information to the user by a predetermined method. In this case, the mobile terminal may be configured to provide disaster information using at least one of a radio broadcast receiving function, a television broadcast receiving function, a news site on the Internet, and a disaster bulletin board on the Internet. .

  Although the above-described first to third aspects of the present invention are described with respect to a configuration in which a wireless communication terminal is connected to a mobile terminal and used, the present invention is not limited to such a mode. For example, the present invention can be applied to a case where a PHS terminal or a mobile phone is used alone as a mobile terminal.

  According to the present invention, a mobile terminal in which the software of the present invention is installed, and a wireless communication terminal including a storage unit such as a nonvolatile memory for storing a control flag for instructing the mobile terminal to perform predetermined control. By using it in combination, it is possible to change the configuration of the authentication database installed in the central office or communicably connected to the central office, and use the existing wireless communication network components to On the other hand, predetermined remote control can be executed. In the present invention, it is not necessary to additionally introduce a dedicated device such as a server in order to remotely control the mobile terminal. Furthermore, since the exchange of data necessary for remote control of the mobile terminal is completed during the location registration authentication procedure with the wireless communication terminal, wireless resources are wasted compared to the prior art that requires dial-up connection. It is possible to reduce the telephone charge imposed on the user without using it.

  A block diagram of a wireless communication network of the present invention is shown in FIG. The network shown in FIG. 1 is constructed using components used in a conventional wireless communication network, and is used by being connected to a mobile terminal 101 (for example, a notebook PC) owned by a user and the user. A wireless communication terminal (for example, a PHS communication card) 102, a wireless base station 103, a communication network 104 such as the Internet, and a central station (or authentication center) 105 having a database are included. The database may be external to the central office, in which case it is communicatively connected to the central office. A software program for executing the method of the present invention (hereinafter referred to as “software of the present invention”) is installed in the mobile terminal 101. However, the system of the present invention can be configured to use a PHS terminal or mobile phone in which the software of the present invention is installed instead of the mobile terminal 101 and the wireless communication terminal 102, for example.

  FIG. 2 shows a sequence diagram of information in the conventional location registration operation normally performed in the wireless communication network of FIG. When power is supplied from the mobile terminal 101 and the wireless communication terminal 102 is turned on (step 201), the wireless communication terminal 102 includes an MM (Mobility Management, mobility management) including a unique telephone number set in the wireless communication terminal 102. A location registration request message is transmitted to the radio base station 103 (step 202). An example of the data format of the MM location registration request message is shown in FIG. In this example, the message includes a protocol identifier, a message type, and a terminal number. Prior to location registration, the radio base station 103 transmits an MM authentication request message including a random number (RND) generated by a predetermined method in step 203 to the radio communication terminal 102 in order to confirm the validity of the radio communication terminal 102. To do. In step 204, the wireless communication terminal 102 calculates an MM authentication response message including an authentication calculation result (AUTHP) generated by calculating the RND and the authentication key (PIN) stored in the wireless communication terminal 102 by a predetermined method. Is transmitted to the radio base station 103. The wireless base station 103 transmits a location registration authentication request message including the telephone number of the wireless communication terminal 102 and AUTHP to the central station 105 (step 205). The central office 105 determines that the wireless communication terminal 102 is going to perform a location registration operation based on the received location registration authentication request message, and uses the data stored in the database to receive the received location registration. The content of the authentication request message is determined to match according to a predetermined location registration authentication process. If it is determined to be appropriate, a location registration response message indicating that is transmitted to the radio base station 103 (step 206). Based on the location registration response message transmitted from the central station 105, the radio base station 103 transmits an FM location registration request message including the telephone number of the radio communication terminal 102 to the location information registration center. The location registration operation is completed upon reception of the FM location registration response message indicating completion of location registration transmitted from the registration center (steps 207 and 208). Then, a location registration acceptance message is transmitted to the wireless communication terminal 102.

  FIG. 4 shows a sequence diagram in the operation of the present invention performed in the wireless communication network of FIG. The mobile terminal 101 is installed with the software of the present invention. When power is supplied from the mobile terminal 101 and the wireless communication terminal 102 is turned on (step 401), an MM location registration request message is transmitted from the wireless communication terminal 102 to the wireless base station 103 in the same manner as in FIG. Then, an MM authentication request message and an MM authentication response message are exchanged between the radio base station 103 and the radio communication terminal 102 (steps 403 and 404), and the radio communication terminal 102 is transferred from the radio base station 103 to the central station. A location registration authentication request message including the telephone number and AUTHP is transmitted (step 405). The wireless communication terminal 102 may transmit a location registration request message not only when the power is turned on, but at every predetermined time interval or whenever moving to a service area covered by a different wireless base station, Alternatively, the location registration request message may be transmitted when a predetermined command (location registration request) is issued from the mobile terminal 101 to the wireless communication terminal 102. Based on the received location registration authentication request message, the central office 105 determines that the wireless communication terminal 102 is about to perform a location registration operation, and uses the identification information of the wireless communication terminal stored in the database. Then, the content of the received location registration authentication request message is determined to match according to a predetermined location registration authentication process. In the case of the present invention, the database further includes a control flag indicating whether or not the wireless communication terminal 102 should perform predetermined control (a specific example will be described later in the embodiment) on the mobile terminal 101. It is stored in association with the identification information of the terminal 102. The control flag can be changed manually by the central office operator accessing the database. The control flag can be changed by the user by accessing the database via the Internet or the like. The control flag may be automatically changed by the database itself in response to reception of a predetermined signal from a component such as another server on the network. If the central office 105 determines that the requested wireless communication terminal 102 is appropriate as a result of authentication, the central office 105 displays a control flag indicating whether or not to execute the predetermined control as a predetermined information element of the location registration response message. It is included in (a predetermined empty part in the data format) and transmitted to the radio base station 103 (step 406). Here, when the control flag is set to “ON”, the communication terminal 102 instructs the mobile terminal 101 to execute predetermined control corresponding to the control flag, and sets it to “OFF”. If it is, it is instructed not to perform the predetermined control. An example of the data format of such a location registration response message is shown in FIG. In the example of the data format shown in FIG. 5, the message type, the location registration authentication result (here, “OK”), the user individual information, and the predetermined control information (for example, control indicating whether or not the predetermined control should be performed). Flag), and other information. Thereafter, as in FIG. 2, an FM location registration request message and an FM location registration response message are exchanged between the radio base station 103 and the location information registration center, and the location registration operation is completed (steps 407 and 408). . Further, the radio base station 103 includes the control information in a predetermined information element of the location registration acceptance message and transmits it to the radio communication terminal 102 (step 409). An example of the data format of the location registration acceptance message at this time is shown in FIG. In the present invention, the wireless communication terminal 102 includes storage means such as a nonvolatile memory, and the predetermined control information that is an information element of the transmitted location registration acceptance message is, for example, as shown in FIG. Is remembered. On the other hand, in a system that uses a PHS terminal or mobile phone in which the software of the present invention is installed instead of the mobile terminal 101 and the wireless communication terminal 102, the PHS terminal or mobile phone includes the storage means as described above. Configured.

  The software of the present invention installed in the mobile terminal 101 has a plurality of timer functions. After power is supplied from the mobile terminal 101 to the communication terminal 102, the mobile terminal 101 passes after a predetermined waiting time (T1) elapses. Issues a flag check command to the wireless communication terminal 102 to check the state of the control information (control flag) stored in the storage means (nonvolatile memory) of the wireless communication terminal 102 (step 410). Returns a signal indicating the state of the control flag based on the control information to the mobile terminal 101 in response to the command (step 411). When the control flag is ON, the software of the present invention causes the mobile terminal 101 to execute predetermined control indicated by the control flag (step 412). In order to save power, the power supply to the wireless communication terminal 102 is stopped if possible, and the operation is suspended for a predetermined waiting time (T2) (step 413). ). After the timer counts a predetermined waiting time (T2), the mobile terminal 101 supplies power again to the wireless communication terminal 102 and makes a new location registration request (step 401) and repeats the above-described procedure. When the application program of the mobile terminal 101 continues to use the wireless communication terminal 102 when shifting to the normal state, the software of the present invention does not stop the power supply to the wireless communication terminal 102 and the predetermined waiting time (T2 ) After the elapse of time, a predetermined command (location registration request) may be issued to instruct the wireless communication terminal 102 to newly make a location registration request (step 401). In this embodiment, the trigger for the mobile terminal 101 to issue the flag check command has been described as the completion time of the timer T1 for simplicity. Alternatively, the wireless communication terminal 102 may receive a location registration acceptance message from the wireless base station 103. It is also possible to point in time when the receipt (step 409) is completed, and such a change is merely a design matter for implementing the present invention.

  Thus, in the system of the present invention, by installing the software of the present invention in a mobile terminal and using a wireless communication terminal equipped with a storage means for storing a control flag related to predetermined control for the mobile terminal, By changing the configuration of the database only partially, predetermined remote control can be performed on the mobile terminal using the components of the existing wireless communication network. This means that using the existing wireless communication network, the data stored in the nonvolatile memory in the wireless communication terminal is updated at the stage of the location registration procedure, and the data in the nonvolatile memory is confirmed every predetermined time (T2). This is made possible by the feature of the present invention that the mobile terminal is controlled. According to the present invention, it is not necessary to additionally introduce a dedicated device such as a server in order to remotely control the mobile terminal. In addition, since the exchange of data necessary for the remote control of the mobile terminal is completed during the location registration authentication procedure before the dial-up connection, the wireless resource is compared with the conventional technology that requires the dial-up connection. It is also possible to reduce the telephone charge imposed on the user without wasting it.

  Hereinafter, some embodiments for remotely controlling a mobile terminal in an emergency using the system of the present invention will be described.

  FIG. 8 shows a sequence diagram when the system of the present invention is applied as a system for remotely locking a mobile terminal. The system configuration is the same as in FIG. Hereinafter, in each embodiment of the present invention, the mobile terminal 101 is described as a notebook PC and the wireless communication terminal 102 is used as a PHS communication card that is used by connecting to the PC. When the users of the PC 101 and the PHS communication card 102 are lost, they notify the central office of that fact and that they want to lock the lost PC. Upon receiving the report, the central office operator accesses the database and sets the PC lock flag (control flag indicating whether or not to lock the PC 101) stored in association with the PHS communication card 102 to “ON”. Set (step 800). In this case, the system of the present invention may be configured so that the user can directly access the database via the Internet or the like and set the PC lock flag to ON instead of the above system configuration in which the user reports to the central office. Good.

  FIG. 8 is a specific example of FIG. 4 according to the present embodiment, and the details of the operation are as described above. After a predetermined time (T1) elapses after the power supply to the PHS communication card 102, the PC 101 issues a flag check command (step 810) and checks the state of the PC lock flag stored in the non-volatile memory of the PHS communication card 102. A command is issued accordingly (step 811). When it is confirmed that the PC lock flag is ON (step 812), the software of the present invention locks the PC 101 (step 813). If the PC lock flag is OFF, the PC 101 is shifted to a normal state without being locked, and the PHS communication card 102 is again instructed to perform a location registration request after a predetermined waiting time (T2) has elapsed (step S1). 801), the above procedure is repeated.

  A flowchart of the operation of the system of this embodiment is shown in FIG. The operation of the main part of FIG. 9 is the same as that of FIGS. In FIG. 9, when it is confirmed that the PC lock flag stored in the PHS communication card 102 is ON, the software of the present invention locks the PC 101 (step 908), and then the PC 101 remains locked ( 909). Various methods are conceivable as a method for releasing the lock state. For example, the lock may not be released unless software on which a specific password for unlocking is recorded is installed in the PC 101, or the lock is not released unless the internal information of the PC 101 or the PHS communication card 102 is rewritten at the factory. You may do it. In addition, the software of the present invention performs PHS communication every predetermined time even after the PC 101 is locked in block 909 to enable quick unlocking when a lost PC and PHS communication card are found. A PC lock flag check may be performed on the card 102. With such a configuration, the user can immediately use the found PC 101 by changing the PC lock flag stored in the database to OFF by a declaration of unlocking from the user. Further, when the state of the memory of the PHS communication card is not updated at all due to a state in which wireless communication is not possible, such as when in a foreign country, the software of the present invention is determined so that the PC cannot be used by judging this. It is also possible to configure. For example, the non-volatile memory of the PHS communication card stores information on the date and time when the stored information was last updated, and the software of the present invention allows the PHS communication card to perform wireless communication based on the information. The PC may be locked based on the determination that the state that is not in an environment where the user can be performed continues for a predetermined time.

  On the other hand, when it is confirmed that the PC lock flag stored in the memory of the PHS communication card 102 is OFF, the software of the present invention is not in a state where the PC 101 is lost (that is, the user reports that the PC 101 is lost). PC is not locked. The PC lock flag is checked every time the predetermined standby time (T2) elapses (step 901).

  FIG. 10 shows a sequence diagram when the system of the present invention is used as a system for providing information to a user via a mobile terminal when a disaster occurs. In the present embodiment, the database stores, in addition to the identification information of the PHS communication card 102, for example, address information deeply related to the user of the PHS communication card 102 (for example, home address, relative address, work address, etc.) in advance. Further, a control flag (hereinafter referred to as “disaster flag”) indicating whether or not a disaster has occurred in an area close to these addresses is stored. When a large-scale disaster such as an earthquake occurs in an area close to any of the above addresses, the disaster flag in the database is preferably automatically changed from the “OFF” state to the “ON” state (step 1000). ). Alternatively, the central office operator who has detected the disaster information may manually change the disaster flag in the database. The subsequent operation is the same as in FIG. 8, and the disaster flag is included in the location registration acceptance message and transmitted to the PHS communication card 102 (1009), and stored in the non-volatile memory in the PHS communication card 102. The stored disaster flag is checked by the software of the present invention (step 1011). When the disaster flag is ON, the software of the present invention uses the radio broadcast reception function and the television broadcast reception function of the PC 101 to provide the user with news broadcasts regarding disasters, or automatically uses a web browser. Start up and access news sites and disaster bulletin boards on the Internet. In addition, the mobile terminal may have a buzzer, and the software of the present invention may sound the buzzer to notify the user of the occurrence of the disaster in response to the disaster flag in the ON state.

  FIG. 11 shows a sequence diagram when the system of the present invention is used as a system for automatically upgrading software installed on the PC 101. In the present embodiment, the database stores in advance the identification information of the PHS communication card 102, for example, software version information such as a web browser installed in the PC 101, and the software (for example, security) A control flag (hereinafter referred to as “version upgrade flag”) indicating whether or not an urgent version upgrade is required (because of the above serious defect) is stored. When it is confirmed that the software needs to be upgraded due to a serious defect, etc., the upgrade flag stored in the database is preferably automatically changed from the “OFF” state to the “ON” state. (Step 1100). Alternatively, the central office operator who has detected information on such a serious defect may manually change the version upgrade flag in the database. Subsequent operations are the same as those in FIGS. When the upgrade flag received by the PHS communication card 102 and stored in the memory is ON, the software of the present invention provides the latest version to upgrade the corresponding software installed in the PC 101. Automatically access websites, download necessary data, and perform version upgrades. Alternatively, the software of the present invention may be configured to notify the user of the fact by displaying on the screen of the PC 101 that the version upgrade is necessary. In this case, the user downloads necessary data himself and executes version upgrade.

  As described above, the present invention has been described mainly taking the case of application to a PHS communication system as an example, but the present invention is not limited to such an embodiment. As described in this specification, the present invention provides control information indicating whether or not to perform predetermined control for a mobile terminal in a location registration procedure, between a central station, a radio base station, and a radio communication terminal. A configuration in which the control flag in the non-volatile memory included in the wireless communication terminal is rewritten and the control flag state in the memory is frequently checked by transmitting the data included in a predetermined empty part in the data format exchanged in It has the characteristics.
