Description

  The present invention relates to a lock method, a wireless portable terminal device, and a wireless portable terminal device that lock or unlock an application by remote operation using unique information of the wireless portable terminal device in the field of wireless mobile communication technology such as a cellular phone. Including network systems.

  In recent years, various applications related to personal data such as a telephone directory and e-mail are installed in wireless portable terminal devices, particularly mobile phones, in addition to telephone functions. However, along with the widespread diversity, not only monetary damage caused by unauthorized use by a third party in the event of loss or theft, but also the acquisition of personal data, misuse of the acquired data, and regular use It is a problem that people suffer.

  Therefore, when a wireless portable terminal device is lost or stolen, a legitimate user or the like can perform key locks on the wireless portable terminal device, restriction of the destination, prohibition of browsing personal data, etc. by remote operation. A method has been proposed in which security can be maintained by locking the application. As an example, a third party who obtains the wireless portable terminal device by a third party who has been set in a protected state by a remote user via a short message service (Short Message Service: hereinafter abbreviated as SMS) by remote operation. If an incorrect protection code is entered, the operation of the wireless mobile terminal will be restricted, the contact information of the owner will be displayed on the display screen, and a protection state will be set in which only one specific number can be sent. This is a technique for sending position and usage information to a specific number via SMS (see, for example, Patent Document 1).

  However, in order to send and receive SMS, it is necessary to establish a wireless connection between the wireless portable terminal device and the network and enter a standby state in which the wireless portable terminal device can receive SMS.

  FIG. 10 shows a schematic diagram of a processing sequence related to establishment of a wireless connection between a conventional wireless portable terminal device and a network. FIG. 10 shows the processing sequence from the outside of the service area to the standby state and receiving the SMS in the processing sequence of the wireless portable terminal device and the network. The left hand side of FIG. 10 is the wireless portable terminal device, and the right hand side is the network, and shows that the processing proceeds by taking the time axis from the top to the bottom of FIG. After the power is turned on 1001, activation processing of the wireless portable terminal device is performed by the activation sequence 1002. The period from the end of the activation sequence 1002 to before the standby state 1011 described later is an out-of-service state where a wireless connection cannot be established. First, a band search request 1003 for confirming the frequency of a standby channel is transmitted from the wireless portable terminal device to the network, and as a response, a band search response 1004 is transmitted from the network to the wireless portable terminal device. . Next, a broadcast information acquisition request 1005 requesting frequency information of the mobile phone carrier company to which the terminal is subscribed, which is more detailed information than the band search request 1003, is transmitted from the wireless portable terminal device to the network. As a response, a broadcast information acquisition response 1006 is transmitted from the network to the wireless portable terminal device. Further, a message of a cell selection response 1008 for a cell selection request 1007 for requesting information for selecting a cell that is a wireless area for communication between the wireless portable terminal device and the network, and a location registration response 1010 for a location registration request 1009 Are exchanged. When these messages are exchanged normally, a wireless connection between the wireless portable terminal device and the network is established, and the wireless portable terminal device enters a standby state 1011.

  The standby state 1011 and the subsequent states are in a range state, and an SMS incoming call or the like is possible. In order to perform SMS communication, a paging (incoming notification) 1012 is transmitted from the network to the wireless portable terminal device, and a paging response 1013 is transmitted from the wireless portable terminal device to the network as a response. Next, the wireless portable terminal device performs processing for receiving actual SMS data from the network at the data reception 1014 and transmitting a data reception response 1015 to the network. Note that the message in FIG. 10 is a typical message described as an example for explanation. Also, in FIG. 10, the wireless base station device between the wireless portable terminal device and the network is not necessary for explaining the present invention, so the description is omitted, and the connection between the wireless portable terminal device and the network is illustrated. Is described.

The wireless portable terminal device and the network are connected by wireless communication. If the connection cannot be maintained when the radio wave condition is bad, it is necessary to return from the standby state 1011 to the band search request 1003 and to repeat the process for establishing the connection from the band search request 1003 to the location registration request 1010.

  However, in the conventional lock method by remote control by SMS transmission / reception, the wireless portable terminal device is set to shift to a protection state in which the application is locked by incoming SMS, so that it is stable in a standby state where SMS transmission / reception can be performed. Need to be. If the radio wave condition is so bad that the standby state cannot be maintained or is unstable enough to repeat the out-of-service state and the standby state, the incoming SMS may not be performed or may be delayed, and remote operation is not possible. There was a problem that the case where it was impossible or not performed quickly occurred.

  The present invention has been made to solve the conventional problem. Even when the radio wave condition is unstable, if the wireless portable terminal device can perform communication until the cell to be communicated is specified, When the user or the like registers the operation restriction such as lock by remote operation, the unique information of the wireless portable terminal device lost or stolen is registered in the network, and the unique information of the wireless portable terminal device acquired by communication The wireless portable terminal device that communicated based on the collation result of the unique information is confirmed to match the wireless portable terminal device that should lock the application, and the wireless portable terminal device that performed the communication is remotely PROBLEM TO BE SOLVED: To provide a method capable of performing application lock by operation, a wireless portable terminal device, and a network system including the wireless portable terminal device To.

  In order to solve the above-described conventional problems, a method of locking an application by remote control using unique information of a wireless portable terminal device according to the present invention includes a wireless portable terminal device and a base station device wirelessly connected to the wireless portable terminal device And a step in which the authorized user or the like registers the specific information of the specific wireless portable terminal device that has been lost or stolen in the network from an information terminal such as a personal computer or another portable wireless terminal device, and the wireless portable terminal A step in which the network acquires unique information of the portable wireless terminal device when the device performs communication for specifying a cell; and a wireless portable device acquired by communication with the unique information of the specific wireless portable terminal device registered by the server.

The step of transmitting to the terminal device and the wireless portable terminal device receives the collation result of the unique information from the network, and the wireless portable terminal device confirms that the wireless portable terminal device is to lock the application based on the collation result Then, the structure which has the step which locks a predetermined application is taken.

  With this configuration, the network acquires specific information of the wireless portable terminal device through communication that identifies the cell that is in the state prior to the transition to the standby state, and locks a predetermined application registered by an authorized user or the like. It collates with the specific information of the specific wireless portable terminal device that has been lost or stolen, transmits the result of the collation to the wireless portable terminal device, and the wireless portable terminal device collates the unique information transmitted from the network. When it is confirmed that the wireless portable terminal device is to lock the application based on the result, the predetermined application is locked. Therefore, it is possible to identify the wireless portable terminal device that should lock the application by the unique information acquired in the communication before shifting to the standby state, and to transmit the verification result that is a requirement for locking the application. That is, it is possible to reduce the number of messages transmitted and received by wireless communication until the application is locked. If the number of messages to be transmitted and received is small, the probability of successful communication is high even when the radio wave condition is unstable. Therefore, even when the radio wave condition is unstable, the unique information of the wireless portable terminal device is collated, the result can be notified to the wireless portable terminal device, and the application can be locked quickly.

  In particular, the network in the application locking method by remote operation using the unique information of the wireless portable terminal device of the present invention has a server having information of the wireless portable terminal device and the base station device, and an information terminal such as a personal computer.

  With this configuration, when inputting terminal information for locking an application, terminal information is input by an authorized user or the like from an information terminal or another wireless portable terminal device, and the network uses the input terminal information as a server. The unique information of the wireless portable terminal device to which the application should be locked can be determined from the above information, and the unique information can be specified by accurate information.

  In particular, the wireless portable terminal device in the application locking method by remote operation using the unique information of the wireless portable terminal device of the present invention includes a step of measuring a time during which an out-of-service state where communication cannot be performed, The step of presetting the time to be used for collation with the duration of the continuation, and the step of collating the time during which the out-of-service state continues with the preset time, the duration of the out-of-service state being equal to or longer than a predetermined time Monitor whether it will be. When the time during which the out-of-service state continues is longer than a preset time, a step of locking a predetermined application is provided.

  With this configuration, by setting in advance the time to lock the application when the out-of-service state continues, it is possible to reliably lock the application even when remote operation cannot be performed without receiving radio waves. .

  In particular, in the network in the application locking method by remote operation using the unique information of the wireless portable terminal device of the present invention, the wireless portable terminal device in which the out-of-service state continues to become the application locked state moves, etc. The network acquires specific information of the wireless portable terminal device when the communication is performed to identify the cell, and the network is configured to lock the application registered in the server to the specific wireless portable terminal device. The step of collating the unique information with the unique information of the wireless portable terminal device acquired by communication, the step of transmitting the unique information collation result to the wireless portable terminal device, and the wireless portable terminal device receiving the result of the matching from the network And the mobile phone that should lock the application from the verification result Check that it is not identical to the end device is configured to have a step of unlocking the application.

  With this configuration, even if the application is locked in a state where radio waves do not reach, if the wireless portable terminal device is in a state where communication can be performed due to movement, the wireless terminal device that has performed communication The wireless mobile terminal device that communicated with the specific information of the specific wireless mobile terminal device that should lock the application registered in the network locks the application based on the network verification result It is possible to quickly unlock the application after confirming that it does not match the wireless mobile terminal device that should be.

  According to the present invention, even when the radio wave state is unstable and the standby state cannot be stably maintained, the unique information of the wireless portable terminal device is acquired by communication for identifying the cell before the transition to the standby state. Thus, the authorized user or the like collates the specific information determined from the terminal information registered in the information terminal or other wireless portable terminal device, and notifies the wireless portable terminal device of the collation result. It is possible to maintain security by locking the application of the wireless portable terminal device.

  Even when the radio wave condition is bad and the wireless connection with the network cannot be established, if the out-of-service state continues for a predetermined time or more, security can be maintained by locking the application.

FIG. 1 shows a method for locking an application by remote control using mobile phone specific information according to Embodiment 1 of the present invention, and a system for explaining a mobile phone and a network. In FIG. 1, a network 15 is connected to wireless base stations 14 and 17, an information terminal 13 such as a general personal computer, and a server 16 of a mobile phone carrier company, and forms a network including a Web site. The server 16 has mobile phone carrier company mobile phone and base station data, and can determine unique information (International Mobile Equipment Identifier: hereinafter abbreviated as IMEI) based on terminal information registered by the authorized user. . The wireless base station 14 is wirelessly connected to a plurality of mobile phones 11 and 12, and the wireless base station 17 is wirelessly connected to a mobile phone 18 that has been lost or stolen. The radio base station 17 is located at a remote location from the radio base station 14 and the information terminal 13.

  When the authorized user of the mobile phone 18 that has been lost or stolen notices that the mobile phone 18 has been lost or stolen, the mobile phone carrier company in the network 15 can use the information terminal 13 or another mobile phone 11 or 12 terminal. The terminal information is registered in the network 15 by accessing the prepared website.

  FIG. 2 is an example of a screen for inputting terminal information to lock an application when accessing a Web site prepared by the mobile phone carrier company of Embodiment 1 of the present invention. When the authorized user locks the application of the mobile phone 18 that has been lost or stolen, the authorized user inputs the terminal information of the contractor name 201, the terminal number 202, and the terminal security code 203 on the screen of FIG. , Registration to the network 15 is performed.

  The server 16 determines the specific IMEI from the terminal information received from the network 15 and registers the specific IMEI in the network 15. Next, the network 15 acquires the IMEI from the mobile phone 18 that is wirelessly connected or has been lost or stolen, and compares the registered IMEI with the IMEI acquired from the mobile phone 18. Thus, the IMEI verification result is transmitted via the base station 17 in order to lock the application.

FIG. 3 illustrates a processing flow of the network 15 when the terminal information of the mobile phone 18 that locks the application is registered on the screen of FIG. First, if the authorized user inputs terminal information on the screen on the website of FIG. 2 and there is no problem such as the entry and the password do not match, the input terminal information is registered in the network 15 ( S31). The network 15 transmits the registered terminal information to the server 16 of the mobile phone carrier company with which the mobile phone 18 has a contract (S32). The server 16 stores in advance the terminal information of the mobile phone 18 and the IMEI in association with each other. The server 16 calculates the specific IMEI from the terminal information transmitted from the network and the registered data of the contractor held by the server 16 (S33), transmits the determined specific IMEI to the network 15, and the network 15 transmits the specified identification. The IMEI is held (S34). This specific IMEI is the IMEI of the mobile phone 18 that locks the application.

  FIG. 4 shows a flowchart of a method of locking an application by remote operation using the specific information of the mobile phone according to the first embodiment of the present invention. FIG. 4 compares the IMEI of the mobile phone that locks the application acquired from the server 16 and the IMEI of the mobile phone 18 acquired by communication via the base station 17 and notifies the mobile phone 18 of the verification result. A flow is shown in which the application is locked when the mobile phone 18 receives a match of the collation result.

  In FIG. 4, first, the mobile phone 18 captures radio in order to perform radio communication with the base station 17 (S41), and notifies the network 15 of IMEI when communicating with the base station 17 (S42). . The network 15 collates the IMEI obtained by communication with the mobile phone 18 and the specific IMEI determined by the server 16 (S43), and returns a collation result to the mobile phone 18. If there is a matching IMEI (S44), the network 15 notifies the mobile phone 18 of the collation result that the IMEI matches (S45), and the mobile phone 18 locks a predetermined application (S46). . If there is no matching IMEI (S44), the network 15 notifies the mobile phone 18 of the collation result that the IMEI does not match (S47), and the mobile phone 18 performs normal processing (S48). In this normal processing, if the application is already locked at the stage of moving to step 48, the application is unlocked, and if the application is not locked, no release processing is performed. Includes both cases of processing. The release process is the same as when registering on the screen in FIG. 2 when the mobile phone is found after the application lock operation is performed on the screen in FIG. 2 when the authorized user loses the mobile phone. And register the cancellation.

  In addition, the matching of the collation result of the unique information used in the present invention is to identify whether the wireless portable terminal device that locks the pre-registered application and the wireless portable terminal device that has notified the unique information by wireless communication are the same. It is not fixed to either complete match or partial match as unique information match.
