Japanese Unexamined Patent Publication No. 2007-271806

In the technique of Patent Document 1, when the display device fails, it may not be possible to display the bar code in which the contents of the information storage memory are converted. Then, it becomes impossible to take a bar code with the mobile terminal, and it becomes impossible to acquire the system information stored in the information storage memory. Therefore, when the display device fails, the system information cannot be confirmed, and the cause of the failure cannot be investigated. Therefore, the present specification provides a technique capable of acquiring information related to the setting of the mobile terminal regardless of the state of the terminal body.

This specification discloses a mobile terminal. This mobile terminal is attached to the terminal body, the terminal body, a terminal IC tag for storing terminal setting-related information related to the setting of the mobile terminal, and the terminal provided in the terminal body. It includes an IC tag, a wireless communication interface for executing wireless communication, and a control unit provided in the terminal body. The control unit establishes a first communication link with the terminal IC tag via the wireless communication interface, and writes including the terminal setting-related information by using the established first communication link. The instruction is supplied to the terminal IC tag. When the terminal IC tag acquires the write instruction from the control unit, the terminal IC tag stores the terminal setting-related information included in the write instruction. Further, when a second communication link is established between the terminal IC tag and an external terminal different from the mobile terminal, and a reading instruction is obtained from the external terminal using the second communication link. In addition, the stored terminal setting-related information is supplied to the external terminal by using the second communication link.

According to such a configuration, the terminal setting-related information can be stored in the terminal IC tag attached to the terminal body. Further, the terminal setting-related information stored in the terminal IC tag can be read by the external terminal. The terminal IC tag is an IC tag that receives radio waves received from the outside, generates electric power, and can perform communication using the generated electric power. Therefore, the external terminal can read the information related to the setting of the mobile terminal regardless of the state of the terminal body. For example, when the terminal body is operating normally, the mobile terminal can perform processing such as displaying terminal setting-related information on the display unit provided in the terminal body, but when the terminal body fails, The mobile terminal cannot perform the above processing. In that case, in the conventional mobile terminal, the user may not be able to confirm the terminal setting information of the mobile terminal. However, according to the above configuration, the terminal IC tag can store the terminal setting-related information, and the external terminal can read the terminal setting-related information. Therefore, even if the terminal body fails, the user can check the terminal setting-related information. That is, the information related to the setting of the mobile terminal can be read regardless of the state of the terminal body.

In the mobile terminal, when the setting of the mobile terminal is changed, the control unit supplies the terminal IC tag with the writing instruction including the terminal setting-related information related to the changed setting. You may.

According to such a configuration, when the setting of the mobile terminal is changed, the terminal setting-related information can be automatically stored in the terminal IC tag. Therefore, the latest terminal setting-related information can be stored in the terminal IC tag.

Further, the control unit may supply the writing instruction to the terminal IC tag every time a predetermined timing arrives.

According to such a configuration, the latest terminal setting-related information can be periodically stored in the terminal IC tag.

Further, the terminal setting-related information included in the writing instruction includes protection information protected by using the first authentication information, and the protection information succeeds in authentication using the first authentication information. The information may be accessible in some cases.

According to such a configuration, the protection information can be accessed only when the authentication using the first authentication information (for example, the first password) is successful, and the protection information cannot be accessed if the authentication is not successful. Therefore, it is possible to suppress a situation in which an unspecified number of third parties can unreasonably access the protected information. For example, information that is not intended to be disclosed to anyone other than a specific person can be used as protection information, and the protection information can be protected by the first authentication information.

The terminal IC tag is protected by using a second authentication information unique to the mobile terminal, and the related information included in the writing instruction when the authentication using the second authentication information is successful. May be memorable.

According to such a configuration, the terminal IC tag is protected by using the second authentication information unique to the mobile terminal (for example, the second password using the serial number unique to the mobile terminal). Only when the authentication is successful, it is allowed to write the information in the terminal IC tag. The second authentication information is authentication information unique to the mobile terminal. Therefore, for example, if the second authentication information is stored only in the mobile terminal, there is a high possibility that the authentication by the control unit of the mobile terminal will succeed, but the authentication by an external terminal different from the mobile terminal may succeed. Will be low. Therefore, writing information to the terminal IC tag from an external terminal different from the mobile terminal may be restricted by the second authentication information. This makes it possible to prevent the information stored in the terminal IC tag from being illegally rewritten by the external terminal.

The terminal setting-related information included in the writing instruction may be information specified by the user.

According to such a configuration, only the information considered to be necessary by the user of the mobile terminal can be stored in the terminal IC tag as the terminal setting-related information. Therefore, only the necessary information can be read by the external terminal.

The wireless communication interface may also be capable of performing wireless communication with an external IC tag existing outside the mobile terminal. The control unit further establishes a third communication link with the external IC tag via the wireless communication interface, and uses the established third communication link to use the external IC tag. The external information stored in the external IC tag may be acquired from the above.

According to such a configuration, since the control unit of the mobile terminal acquires the external information stored in the external IC tag, the external information can be stored in the mobile terminal as a backup. The external IC tag is also an IC tag capable of receiving electric waves received from the outside (for example, a mobile terminal) to generate electric power and performing communication using the generated electric power. Therefore, even if the external terminal breaks down, the external information can be confirmed on the mobile terminal. Alternatively, the terminal setting-related information related to the setting of the mobile terminal can be stored in advance in an external IC tag for backup. Then, the control unit of the mobile terminal can acquire external information for backup (that is, terminal setting-related information) from the external IC tag. As a result, when the terminal setting-related information stored in the mobile terminal is lost, the terminal setting-related information can be restored from the external IC tag.

The external IC tag is provided in the external terminal, and the external information may include external setting-related information related to the setting in the external terminal. When the external information is acquired, the control unit may change the setting of the mobile terminal by using the external setting-related information included in the external information.

According to such a configuration, the setting of the external terminal can be inherited as the setting of the mobile terminal. Therefore, for example, after repairing a broken mobile terminal, the setting saved in the external terminal as a backup can be inherited as the setting of the repaired mobile terminal.

(First Example)
(Configuration of communication system 2; FIG. 1)
The communication system 100 shown in FIG. 1 includes a mobile terminal 10 and a plurality of external terminals 50. The mobile terminal 10 and the plurality of external terminals 50 are arbitrary portable terminal devices such as a portable information code reading device, a smartphone, a mobile phone, and a PDA.

(Structure of mobile terminal 10; FIGS. 1 and 2)
As shown in FIG. 2, the mobile terminal 10 includes a terminal body 12 and a terminal IC tag 30 attached to the terminal body 12. The terminal body 12 includes an operation unit 14, a display unit 16, an NFC (Near Field Communication) interface 18, a control unit 20, and a memory 22. In the following, the interface will be referred to as "I / F".

The operation unit 14 includes a plurality of buttons. The user of the mobile terminal 10 can perform various inputs to the mobile terminal 10 by operating the operation unit 14. The display unit 16 is a display for displaying various information related to the mobile terminal 10.

The NFCI / F18 is a wireless communication interface for executing wireless communication (hereinafter referred to as "NFC communication") according to the terminal IC tag 30 and the NFC method. The NFC system is, for example, a short-range wireless communication system based on the international standard of ISO / IEC21481 or 18092. The control unit 20 establishes an NFC communication link with the terminal IC tag 30 via the NFCI / F18, and executes NFC communication using the established NFC communication link to communicate with the terminal IC tag 30. Various information can be communicated between them. Similarly, the NFCI / F18 can also execute NFC communication with the external IC tag 70 of the external terminal 50 described later. That is, the control unit 20 establishes an NFC communication link with the external IC tag 70 via the NFCI / F18, and executes the NFC communication using the established NFC communication link, whereby the external IC tag 70 is executed. Various information can also be communicated with.

The control unit 20 executes various processes according to the program in the memory 22. The contents of the processing (see FIGS. 3 and 4) executed by the control unit 20 will be described later.

The memory 22 stores various information in addition to the above program. The memory 22 contains, for example, information representing various settings of the mobile terminal 10 (for example, the SSID (Service Set Identifier) and password of the access point to which the mobile terminal 10 is connected, the OS version information, the serial number of the mobile terminal 10 and the like. The IP address assigned to the mobile terminal 10) is stored. The memory 22 also stores various information irrelevant to the settings of the mobile terminal 10, such as communication records by the mobile terminal 10 and image data acquired from the outside by the mobile terminal 10. Further, the memory 22 stores a second password (described later) used for authentication for releasing the write restriction of the terminal IC tag 30.

The terminal IC tag 30 is an IC tag that generates electric power by using radio waves received from the outside (for example, NFCI / F18 of the mobile terminal 10, NCCI / F58 of the external terminal 50, etc.) and operates by using the electric power. be. The terminal IC tag 30 stores terminal setting-related information. The terminal setting-related information is information related to the setting of the mobile terminal 10 among various information stored in the memory 22. The terminal setting-related information may be rephrased as the system information of the mobile terminal 10. The terminal setting-related information includes, for example, the SSID and password of the access point, the OS version information, the serial number of the mobile terminal 10, the IP address assigned to the mobile terminal 10, and the communication record by the mobile terminal 10, the mobile terminal 10. Does not have to include image data or the like acquired from the outside. What kind of information should be included in the terminal setting-related information is specified in advance by the user. The terminal setting-related information is stored in the terminal IC tag 30 when the control unit 20 executes a backup process (see FIG. 3) described later.

The terminal setting-related information stored in the terminal IC tag 30 may include protection information. The protected information is information protected by a first password (an example of the first authentication information). The first password is, for example, a character string predetermined by the user. Read restrictions are set for the protection information by the first password. The protected information can be accessed only when the authentication using the first password is successful. When a first-class device (for example, the control unit 60 of the external terminal 50) wishing to access the protection information opens the protection information file, the protection information requires the input of the first password. If the password entered by the first-class device matches the first password, the authentication is successful. In this case, the first-class device can open the protection information file and can recognize (that is, access) the contents of the protection information. On the other hand, if the entered password does not match the first password, the first-class device cannot open the protection information file and cannot recognize the contents of the protection information (that is, cannot access it). .. For example, among the various information included in the above terminal setting related information, the password of the access point may be the protection information.

Further, in this embodiment, the terminal IC tag 30 is also set with a write restriction by a second password (an example of the second authentication information). The second password is a password generated by using the information unique to the mobile terminal 10, and is predetermined by the vendor of the mobile terminal 10. In this embodiment, the second password is a password generated by using the serial number of the mobile terminal 10. The second password is stored in advance only in the memory 22 of the mobile terminal 10 by the vendor. That is, it can be said that the second password is the authentication information unique to the mobile terminal 10. In other words, the terminal IC tag 30 is protected by a second password. That is, the second type of device (for example, the control unit 20 of the mobile terminal 10, the control unit 60 of the external terminal 50, etc.) that wants to supply (that is, write) information to the terminal IC tag 30 uses the second password. Information can be supplied to the terminal IC tag 30 only when the authentication is successful. When the second type device wants to supply the information to the terminal IC tag 30, the terminal IC tag 30 requires the input of the password. If the password entered by the second type device matches the second password, the authentication is successful. In this case, the second type device can supply information to the terminal IC tag 30. On the other hand, if the entered password does not match the second password, the second type device cannot supply information to the terminal IC tag 30. As described above, the second password is information unique to the mobile terminal 10 and is stored only in the memory 22 of the mobile terminal 10. Therefore, terminals other than the mobile terminal 10 (for example, the external terminal 50) cannot know the second password. That is, in this embodiment, only the control unit 20 of the mobile terminal 10 can succeed in the authentication using the second password, and the other devices (for example, the control unit 60 of the external terminal 50) are the second. Successful password-based authentication is nearly impossible. That is, in this embodiment, the terminal IC tag 30 is set so that only the control unit 20 of the mobile terminal 10 can write information to the terminal IC tag 30.

(Configuration of external terminal 50; FIGS. 1 and 2)
Next, the configuration of the external terminal 50 will be described. Each of the plurality of external terminals 50 shown in FIG. 1 has a similar configuration. The configuration of the external terminal 50 is the same as the configuration of the mobile terminal 10 described above. As shown in FIG. 2, the external terminal 50 includes a terminal main body 52 and an external IC tag 70 attached to the terminal main body 52. The terminal body 52 includes an operation unit 54, a display unit 56, an NFCI / F58, a control unit 60, and a memory 62.

The terminal body 52, the external IC tag 70, the operation unit 54, the display unit 56, the NFCI / F58, the control unit 60, and the memory 62 in the external terminal 50 are the terminal body 12, the terminal IC tag 30, and the operation unit in the mobile terminal 10, respectively. It corresponds to 14, the display unit 16, the NFCI / F18, the control unit 20, and the memory 22, and each has the same configuration. However, external information is stored in the external IC tag 70 of the external terminal 50. The external information includes external setting-related information related to the setting of the external terminal 50.

(Backup process; Fig. 3)
Next, with reference to FIG. 3, the contents of the backup process executed by the control unit 20 of the mobile terminal 10 will be described. The backup process is a process for the control unit 20 to store the terminal setting-related information in the terminal IC tag 30. When the power of the mobile terminal 10 is turned on, the control unit 20 starts the backup process of FIG.

When the control unit 20 starts the backup process, the control unit 20 starts monitoring S11 and S21. In S11, the control unit 20 monitors that the setting change by the user is executed. For example, the user of the mobile terminal 10 can operate the operation unit 14 to change the setting of the mobile terminal 10. For example, the OS version of the mobile terminal 10 may be updated according to the user's operation. In this way, when the setting of the mobile terminal 10 is changed, the control unit 20 determines YES in S11 and proceeds to S12.

In S12, the control unit 20 determines whether or not the information indicating the changed setting is the target of backup. As described above, the type of information to be included in the terminal setting-related information to be stored in the terminal IC tag 30 is specified in advance by the user. The control unit 20 refers to a list of information types specified in advance by the user, and determines whether or not the information indicating the changed setting is included in the list. When the information indicating the changed setting is included in the list, the control unit 20 determines YES in S12 and proceeds to S13. On the other hand, if the information indicating the changed setting is not included in the list, the control unit 20 determines NO in S12 and returns to the monitoring of S11 and S21.

In S21, the control unit 20 monitors that a predetermined timing has arrived. The predetermined timing is a preset backup timing. For example, the predetermined timing may be the timing when midnight arrives. In another example, the predetermined timing may be 24 hours after the last backup. The predetermined timing can also be set by the user. When the predetermined timing arrives, the control unit 20 determines YES in S21 and proceeds to S13.

In S13, the control unit 20 establishes an NFC communication link with the terminal IC tag 30 via the NFCI / F18. Specifically, the control unit 20 activates the NFCI / F18 to output radio waves toward the terminal IC tag 30. In the mobile terminal 10 of this embodiment, the terminal IC tag 30 is arranged at a distance at which the radio waves output from the NFCI / F18 can be received. When the terminal IC tag 30 receives the radio wave and responds to the NFCI / F18, an NFC communication link is established between the NFCI / F18 and the terminal IC tag 30. The NFC communication link established in S13 is an example of the "first communication link".

In the following S14, the control unit 20 supplies a write request to the terminal IC tag 30 by using the NFC communication link established in S13. The write request is a signal for requesting the terminal IC tag 30 for permission to supply (that is, write) information. The write request includes a second password stored in memory 22.

In the following S15, the control unit 20 determines whether or not the write restriction has been released. When the terminal IC tag 30 acquires the write request of S14, it authenticates whether or not the password included in the write request matches the second password. As described above, since the write request in S14 includes the second password, the authentication by the terminal IC tag 30 succeeds. When the authentication is successful, the terminal IC tag 30 supplies the mobile terminal 10 with an OK signal indicating that the authentication is successful (that is, writing is permitted). When the control unit 20 receives the OK signal from the terminal IC tag 30, it determines YES in S15 and proceeds to S16. On the other hand, when the authentication in the terminal IC tag 30 fails due to some factor (for example, when the second password stored in the memory 22 is damaged), the terminal IC tag 30 refers to the mobile terminal 10 with respect to the mobile terminal 10. , Provides an NG signal indicating that authentication has failed (ie, write is not allowed). When the control unit 20 receives the NG signal from the terminal IC tag 30, it determines NO in S15 and ends the backup process of FIG. 3 with an error. In this case, the control unit 20 performs a predetermined error notification operation including displaying an error message on the display unit 16.

In S16, the control unit 20 creates a write instruction. The write instruction is a signal for instructing the terminal IC tag 30 to store the terminal setting-related information included in the write instruction. The write instruction includes terminal setting related information at this time. That is, the terminal setting-related information included in the write instruction in S16 includes all the information of the type previously specified by the user among the information related to the setting of the mobile terminal 10 stored in the memory 22 at this time. .. In particular, specifically, when S16 is performed due to the setting being changed by the user (YES in S11 and S12), the terminal setting-related information includes information indicating the changed setting. The terminal setting-related information includes protection information specified in advance by the user. Therefore, the write instruction created in S16 includes protection information.

In the following S17, the control unit 20 supplies the terminal IC tag 30 with the write instruction generated in S16 by using the established NFC communication link. When the terminal IC tag 30 acquires the write instruction in S17, the terminal IC tag 30 newly stores the terminal setting-related information included in the acquired write instruction instead of the terminal setting-related information currently stored. As a result, the terminal IC tag 30 stores the latest terminal setting-related information at this time.

In the following S18, the control unit 20 disconnects the NFC communication link. Specifically, the control unit 20 stops the NFCI / F18 from outputting radio waves. As a result, the first communication link between the NFCI / F18 and the terminal IC tag 30 is disconnected. After finishing S18, the control unit 20 returns to the monitoring of S11 and S21.

(Information acquisition process; Fig. 4)
Next, with reference to FIG. 4, the content of the information acquisition process executed by the control unit 20 of the mobile terminal 10 will be described. The information acquisition process is a process for the control unit 20 to acquire external information from the external IC tag 70. When the power of the mobile terminal 10 is turned on, the control unit 20 starts the information acquisition process of FIG.

When the control unit 20 starts the information acquisition process, the control unit 20 starts monitoring S31. In S31, the control unit 20 monitors whether or not a predetermined read start instruction has been input by the user. The user of the mobile terminal 10 can operate the operation unit 14 to input a reading start instruction to the mobile terminal 10. The reading start instruction is a signal for instructing to start the process of reading the external information stored in the external IC tag 70 (that is, the information acquisition process). When the reading start instruction is input by the user, the control unit 20 determines YES in S31 and proceeds to S32.

In S32, the control unit 20 monitors via the NFCI / F18 that an NFC communication link is established with an external IC tag (for example, the external IC tag 70 of the external terminal 50). Specifically, the control unit 20 activates the NFCI / F18 to output radio waves in a direction different from that of the terminal IC tag 30. At this time, the NFCI / F18 does not output radio waves toward the terminal IC tag 30. Therefore, an NFC communication link is not established between the NFCI / F18 and the terminal IC tag 30. If the NFCI / F18 and the external IC tag 70 of the external terminal 50 approach each other within a predetermined distance while the NFCI / F18 is outputting radio waves, the external IC tag 70 receives the radio waves output by the NFCI / F18. .. When the external IC tag 70 receives radio waves and responds to the NFCI / F18, an NFC communication link is established between the NFCI / F18 and the external IC tag 70. When the NFC communication link is established between the NFCI / F18 and the external IC tag 70, the control unit 20 determines YES in S32 and proceeds to S33. The NFC communication link established in S32 is an example of the "third communication link". After that, when the mobile terminal 10 and the external IC tag 70 are separated by a predetermined distance or more, the NFC communication link is disconnected.

In S33, the control unit 20 supplies a read instruction to the external IC tag 70 by using the established NFC communication link. The reading instruction is a signal for instructing the external IC tag 70 to supply the external information stored in the external IC tag 70 to the mobile terminal 10. When the external IC tag 70 acquires the reading instruction supplied by the control unit 20, the external IC tag 70 supplies the external information to the mobile terminal 10 by using the NFC communication link. The external information includes external setting-related information related to the setting of the external terminal 50. In addition, the external setting-related information includes protection information designated in advance by the user. The protected information is the information protected by the first password.

In the following S34, the control unit 20 acquires the external information supplied by the external IC tag 70 by using the NFC communication link. The control unit 20 can acquire the external setting-related information included in the external information and the protection information included in the external setting-related information.

In the following S35, the control unit 20 attempts to access the protection information included in the acquired external information. Specifically, the user of the mobile terminal 10 inputs a password for accessing the protection information included in the external information by operating the operation unit 14. If the password entered by the user matches the password for accessing the protected information, the authentication is successful. When the control unit 20 succeeds in the authentication using the password, the control unit 20 can access the protection information included in the external information. If the authentication fails, the control unit 20 cannot access the protection information. If the external setting information does not include the protection information, the control unit 20 skips S35.

In the following S36, the control unit 20 displays the external setting-related information included in the acquired external information on the display unit 16. On the display unit 16, for example, external setting-related information such as the SSID of the access point of the external terminal 50 and the version information of the OS is displayed. Further, when the control unit 20 succeeds in accessing the protection information using the password in the above S35, the control unit 20 also displays the protection information included in the external setting related information in the display unit 16 in S36. For example, when the password of the access point is specified in the protection information, the password of the access point is displayed on the display unit 16 when the access to the protection information is successful.

In the following S37, the control unit 20 determines whether or not the reflection instruction has been input by the user. For example, the user of the mobile terminal 10 can operate the operation unit 14 to input the reflection instruction to the mobile terminal 10 while the external setting-related information is displayed on the display unit 16. The reflection instruction is a signal for instructing the display unit 16 to reflect the setting specified by the external setting-related information displayed on the display unit 16 in the setting of the mobile terminal 10. When the reflection instruction is input by the user, the control unit 20 determines YES in S37 and proceeds to S38. On the other hand, if the reflection instruction is not input, the control unit 20 determines NO in S37 and returns to S31. For example, if the user does not want to reflect the settings specified by the external setting related information (SSID of the access point of the external terminal 50, OS version information, etc.) in the settings of the mobile terminal 10, the user does not input the reflection instruction.

In S38, the control unit 20 stores the external setting-related information in the memory 22. The setting of the mobile terminal 10 stored in the memory 22 is changed based on the external setting related information. That is, the control unit 20 reflects the setting of the external terminal 50 specified by the external setting related information in the setting of the mobile terminal 10. For example, the control unit 20 changes the SSID, OS version information, etc. of the access point of the mobile terminal 10 to the SSID, OS version information, etc. of the access point of the external terminal 50. The control unit 20 changes the setting of the mobile terminal 10 by using the information related to the external setting. As a result, the settings of the external terminal 50 are inherited by the mobile terminal 10. After finishing S38, the control unit 20 returns to S31.

(Specific example of operation; FIGS. 5 to 7)
Subsequently, specific cases A to C realized by the flowcharts of FIGS. 3 and 4 will be described with reference to FIGS. 5 to 7. Cases A to C are examples of operations executed between the mobile terminal 10 and the external terminal 50.

(Case A; Fig. 5)
Case A is a case in which the external terminal 50 tries to write to the terminal IC tag 30 after the mobile terminal 10 writes the terminal setting-related information to the terminal IC tag 30.

In case A, first, the user of the mobile terminal 10 operates the operation unit 14 to change the setting of the mobile terminal 10 (YES in S11 of FIG. 3). The control unit 20 determines that the information indicating the changed setting is the target of backup (YES in S12), and establishes an NFC communication link with the terminal IC tag 30 via the NFCI / F18 (S13). ). Next, the control unit 20 supplies a write request to the terminal IC tag 30 using the NFC communication link (S14). The write request includes a second password.

The terminal IC tag 30 authenticates whether or not the password included in the write request matches the second password. Authentication is successful in this case. The terminal IC tag 30 supplies an OK signal to the mobile terminal 10.

When the control unit 20 acquires the OK signal (YES in S15), the control unit 20 creates a write instruction including the terminal setting related information (S16), and sends the created write instruction to the terminal IC tag 30 using the NFC communication link. Supply (S17).

When the terminal IC tag 30 acquires the writing instruction, the terminal IC tag 30 stores the terminal setting-related information included in the writing instruction.

After that, the control unit 20 disconnects the NFC communication link with the terminal IC tag 30 (S18).

After that, the user of the external terminal 50 brings the external terminal 50 in a state where a predetermined writing start instruction is input and the NFCI / F58 outputs radio waves closer to the terminal IC tag 30 of the mobile terminal 10. When the distance between the terminal IC tag 30 and the NFCI / F58 of the external terminal 50 becomes shorter than a predetermined threshold value, an NFC communication link is established between the NFCI / F58 and the terminal IC tag 30.

The control unit 60 of the external terminal 50 supplies a write request to the terminal IC tag 30 by using the established NFC communication link. The write request includes a given password. The password is stored in the memory 62. In this case, the password stored in the memory 62 is different from the second password.

The terminal IC tag 30 authenticates whether or not the password included in the write request matches the second password. Authentication fails in this case. The terminal IC tag 30 supplies an NG signal to the mobile terminal 10.

When the control unit 60 acquires the NG signal, the control unit 60 cannot write the information to the terminal IC tag 30. When the control unit 60 acquires the NG signal, the control unit 60 disconnects the NFC communication link with the terminal IC tag 30.

(Case B; Fig. 6)
Case B is a case in which the external terminal 50 reads the terminal setting-related information stored in the terminal IC tag 30.

In case B, first, the user of the external terminal 50 operates the operation unit 54 to input a reading start instruction. Then, the user brings the external terminal 50 in the state where the NFCI / F58 is outputting radio waves closer to the terminal IC tag 30 of the mobile terminal 10. When the distance between the terminal IC tag 30 and the NFCI / F58 of the external terminal 50 becomes shorter than a predetermined threshold value, an NFC communication link is established between the NFCI / F58 and the terminal IC tag 30.

The control unit 60 of the external terminal 50 supplies a reading instruction to the terminal IC tag 30 by using the established NFC communication link.

When the terminal IC tag 30 acquires the reading instruction, the terminal IC tag 30 supplies the stored terminal setting-related information to the external terminal 50 by using the NFC communication link. This terminal setting-related information includes protection information protected by the first password.

When the control unit 60 of the external terminal 50 acquires the terminal setting-related information, the control unit 60 stores the terminal setting-related information in the memory 62.

After that, the user of the external terminal 50 operates the operation unit 54 to input the password. The control unit 60 of the external terminal 50 authenticates whether or not the entered password matches the first password. When the control unit 60 succeeds in the authentication using the first password, the control unit 60 can access the protection information included in the terminal setting related information. On the other hand, the control unit 60 cannot access the protection information when the authentication using the first password fails. The control unit 60 can access the terminal setting-related information other than the protection information without requiring authentication. The control unit 60 displays the acquired terminal setting-related information on the display unit 56.

After that, the control unit 60 disconnects the NFC communication link with the terminal IC tag 30.

(Case C; Fig. 7)
Case C is a case in which the mobile terminal 10 reads the external information stored in the external IC tag 70.

In case C, first, the user of the mobile terminal 10 operates the operation unit 14 to input a reading start instruction (YES in S31 of FIG. 4). Then, the user brings the mobile terminal 10 in which the NFCI / F18 is outputting radio waves closer to the external IC tag 70 of the external terminal 50. When the distance between the external IC tag 70 and the NFCI / F18 of the mobile terminal 10 becomes shorter than a predetermined threshold value, an NFC communication link is established between the NFCI / F18 and the external IC tag 70 (YES in S32). ..

The control unit 20 of the mobile terminal 10 supplies a reading instruction to the external IC tag 70 by using the established NFC communication link (S33).

When the external IC tag 70 acquires the reading instruction, the external IC tag 70 supplies the stored external information to the mobile terminal 10 by using the NFC communication link. This external information includes information related to external settings. In addition, the external setting-related information includes protection information protected by a third password.

When the control unit 20 of the mobile terminal 10 acquires the external information (S34), the control unit 20 stores the external information in the memory 22.

After that, the user of the mobile terminal 10 operates the operation unit 14 to input the password. The control unit 20 of the mobile terminal 10 authenticates whether or not the entered password matches the third password. The control unit 20 attempts to access the protected information including the external information by using the third password (S35). When the control unit 20 succeeds in the authentication using the third password, the control unit 20 can access the protection information included in the external information. On the other hand, the control unit 20 cannot access the protection information when the authentication using the third password fails. The control unit 20 can access the external setting-related information other than the protection information without requiring authentication. The control unit 20 displays the external setting-related information included in the acquired external information on the display unit 16 (S36).

After that, the user of the mobile terminal 10 operates the operation unit 14 to input a reflection instruction (YES in S37). When the reflection instruction is input, the control unit 20 of the mobile terminal 10 reflects the setting specified by the external setting-related information in the setting of the mobile terminal 10 (S38).

After that, the control unit 20 disconnects the NFC communication link with the external IC tag 70.

The configuration and operation of the mobile terminal 10 have been described above. As is clear from the above description, the control unit 20 of the mobile terminal 10 uses the NFC communication link to supply a write instruction including terminal setting-related information to the terminal IC tag 30 (S17 in FIG. 3). When the terminal IC tag 30 acquires a write instruction from the control unit 20, the terminal IC tag 30 stores the terminal setting-related information included in the write instruction. Further, the terminal IC tag 30 supplies the stored terminal setting-related information to the external terminal 50 by using the second communication link.

Therefore, the terminal setting-related information can be stored in the terminal IC tag 30 attached to the terminal body 12 of the mobile terminal 10. Further, the terminal setting-related information stored in the terminal IC tag 30 can be read by the external terminal 50. The terminal IC tag 30 is an IC tag that receives radio waves received from the outside, generates electric power, and can perform communication using the generated electric power. Therefore, even if the terminal body 12 fails, the terminal setting-related information can be acquired. For example, in the above-mentioned mobile terminal 10, if the terminal body 12 is operating normally without failure, the display unit 16 can display the terminal setting-related information (for example, the information in which the terminal setting information is recorded). The code may be displayed), but if the terminal body 12 fails and does not operate normally, the display unit 16 cannot display the terminal setting-related information and the like. Therefore, in this embodiment, the terminal IC tag 30 can store the terminal setting-related information, and the external terminal 50 can read the terminal setting-related information. As a result, even if the terminal body 12 fails, the user can check the terminal setting-related information. That is, the information related to the setting of the mobile terminal 10 can be read regardless of the state of the terminal body 12.

Further, when the terminal body 12 of the mobile terminal 10 fails, if the terminal body 12 is started in the state of failure, the information stored in the memory 62 may be lost due to the unreasonable startup. However, according to the above configuration, the terminal setting-related information can be acquired from the terminal IC tag 30 without activating the terminal body 12 of the mobile terminal 10. Therefore, the terminal setting-related information can be safely acquired without losing the information stored in the memory 62. Further, when the terminal body 12 fails, it is effective to acquire the system information of the mobile terminal 10 and analyze the cause of the failure. Therefore, the above configuration that can safely acquire the terminal setting-related information is particularly effective.

Further, in the above-mentioned mobile terminal 10, when the setting of the mobile terminal 10 is changed (YES in S11 and S12 in FIG. 3), the control unit 20 writes the terminal setting-related information related to the changed setting. The instruction is supplied to the terminal IC tag 30 (S17). According to such a configuration, when the setting of the mobile terminal 10 is changed, the changed terminal setting-related information can be automatically stored in the terminal IC tag 30. As a result, the latest terminal setting-related information can be stored in the terminal IC tag 30.

Further, in the above-mentioned mobile terminal 10, the control unit 20 automatically supplies a writing instruction to the terminal IC tag 30 every time a predetermined period elapses (YES, S17 in S21 of FIG. 3). Therefore, the terminal setting-related information can be periodically stored in the terminal IC tag 30. Even if the user of the mobile terminal 10 forgets to update the terminal setting-related information, the terminal setting-related information can be automatically backed up.

Further, in the above-mentioned mobile terminal 10, the terminal setting-related information included in the writing instruction includes protection information protected by using the first password. This protection information is information that can be accessed when the authentication using the first password is successful. Therefore, the protection information can be accessed only when the authentication using the first password is successful, and the protection information cannot be accessed when the authentication is not successful. Therefore, it is possible to prevent an unspecified number of third parties from gaining unauthorized access to the protected information. In addition, information that is less important to the user and protection information that is more important to the user can be backed up separately.

Further, in the above-mentioned mobile terminal 10, the control unit 20 acquires external information from the external IC tag 70 by using the NFC communication link established with the external IC tag 70 (S34 in FIG. 4). The external IC tag 70 is also an IC tag capable of receiving electric waves received from the outside (for example, the mobile terminal 10) to generate electric power and performing communication using the generated electric power. Therefore, the control unit 20 of the mobile terminal 10 can acquire the external information and store the external information as a backup in the mobile terminal 10. Therefore, even if the external IC tag 70 breaks down, the external information can be confirmed on the mobile terminal 10. Alternatively, the terminal setting-related information related to the setting of the mobile terminal 10 can be stored in advance as external information in the external IC tag 70 for backup. Then, the control unit 20 of the mobile terminal 10 can acquire external information for backup (that is, terminal setting-related information) from the external IC tag 70. As a result, when the terminal setting-related information stored in the mobile terminal 10 is lost, the terminal setting-related information can be restored from the external IC tag 70.

Further, the external information stored in the external IC tag 70 includes the external setting-related information related to the setting in the external terminal 50. When the control unit 20 of the mobile terminal 10 acquires the external information, the control unit 20 changes the setting of the mobile terminal 10 by using the external setting-related information included in the external information. According to such a configuration, the setting of the external terminal 50 can be inherited as the setting of the mobile terminal 10. Therefore, for example, after repairing the broken mobile terminal 10, the setting saved in the external IC tag 70 of the external terminal 50 as a backup can be inherited as the setting of the repaired mobile terminal 10.

Further, in the above embodiment, the terminal IC tag 30 is set with a write restriction by a second password (an example of the second authentication information). Therefore, the control unit 60 of the external terminal 50 cannot write information to the terminal IC tag 30 unless the authentication by the second password is successful. Then, in the above embodiment, the second password is a password generated by using the information unique to the mobile terminal 10, and is stored only in the memory 22 of the mobile terminal 10. Therefore, the control unit 20 of the mobile terminal 10 succeeds in the authentication using the second password stored in the memory 22. As a result, the control unit 20 can release the writing restriction of the terminal IC tag 30 (S15 in FIG. 3) and write information to the terminal IC tag 30 (S17). On the other hand, an external terminal (for example, the external terminal 50) that does not store the second password cannot succeed in authentication. That is, it is restricted that an external terminal writes information to the terminal IC tag 30. Therefore, it is possible to prevent the information stored in the terminal IC tag 30 from being illegally rewritten by the external terminal 50.

Further, in the above embodiment, what kind of information should be included in the terminal setting-related information for backing up to the terminal IC tag 30 is specified in advance by the user. Therefore, the information that the user of the mobile terminal 10 considers necessary can be stored in the terminal IC tag 30 as the terminal setting-related information. Therefore, only the necessary information can be read by the external terminal 50.

Although one embodiment has been described above, the specific embodiment is not limited to the above embodiment. In the following description, the same components as those in the above description will be designated by the same reference numerals and description thereof will be omitted.

In the above embodiment, when the setting of the mobile terminal 10 is changed, the control unit 20 automatically supplies the changed terminal setting-related information to the terminal IC tag 30 even if the user does not give a backup instruction. The configuration is adopted (YES in S11 and S12 in FIG. 3). However, in another embodiment, the control unit 20 may supply the terminal setting-related information to the terminal IC tag 30 only when the user inputs a predetermined backup instruction.

Further, the terminal setting-related information backed up in the terminal IC tag 30 may be information related to a part of the setting of the mobile terminal 10 or information related to all the setting.

In the above embodiment, the terminal IC tag 30 is set with a write restriction by a second password (an example of the second authentication information). Not limited to this, the terminal IC tag 30 may not have a write limit set.

In the above embodiment, when the control unit 20 generates the terminal setting-related information due to the setting being changed by the user (YES, S16 in S11 and S12 in FIG. 3), the memory 22 at this point. Among the information about the setting of the mobile terminal 10 stored in the above, all the information of the type specified in advance by the user is included. Not limited to this, when the control unit 20 generates the terminal setting-related information due to the setting being changed by the user, the terminal setting-related information may include only the information indicating the changed setting. .. In that case, when the terminal IC tag 30 acquires the terminal setting-related information from the control unit 20, the terminal IC tag 30 sets the changed settings included in the newly acquired terminal setting-related information among the already stored terminal setting-related information. Only the information to be represented may be newly stored (that is, updated).

Further, in the above embodiment, the mobile terminal 10 and the external terminal 50 have the same configuration, but the present invention is not limited to this, and the configurations of both may be different. For example, the external terminal 50 does not have to include the external IC tag 70. The external terminal 50 may be able to read the terminal setting-related information of the mobile terminal 10. In this modification, the external IC tag that can be read by the mobile terminal 10 does not have to be mounted on the external terminal 50.

In addition, the technical elements described in the present specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the techniques illustrated in the present specification or drawings achieve a plurality of objectives at the same time, and achieving one of the objectives itself has technical usefulness.
