As shown in FIG. 3, the terminal device 10 includes a detection unit 11, a setting unit 12, and a reception unit 13 as functional blocks.

The detector 11 is configured to detect attachment or detachment of the device unit 50 .

For example, the terminal device 10 and the device unit 50 each have a USB (Universal Serial Bus) connector, and the terminal device 10 supports hot plugging (also called plug-and-play) of USB devices. When the USB connector of the device unit 50 is inserted into the USB connector of the terminal device 10, or when the terminal device 10 and the device unit 50 are electrically connected via the USB cable, the USB bus driver of the terminal device 10 detects connection with the device unit 50, and USB enumeration is started. When the USB enumeration is completed, serial communication (serial transmission) becomes possible between the terminal device 10 and the device unit 50 via the USB signal line. In this case, the detection unit 11 detects attachment of the device unit 50 upon completion of USB enumeration. On the other hand, if the USB bus driver does not detect connection with the device unit 50, it is considered that the device unit 50 is not attached. Alternatively, if there is no communication for a predetermined time after completion of USB enumeration, it is considered that the device unit 50 has been removed. In this case, the detection unit 11 detects separation of the device unit 50 because USB enumeration does not start or there is no communication after completion of USB enumeration.

Based on the result of detection by the detection unit 11, the setting unit 12 selects a first driver that communicates with the device using the first communication method, or communicates with the device using a second communication method different from the first communication method. It is configured to set a second driver to perform.

The first driver and the second driver are device drivers for controlling hardware included in the terminal device 10 or hardware connected to the terminal device 10 by the operating system. In general, a device driver takes charge of correspondence between a device, which is hardware, and an operating system, which is software, particularly an API (Application Programming Interface), which is a part thereof.

The first driver is, for example, a driver that communicates with the device unit 50 via a USB signal line. In this case, the first communication method is a wired communication method conforming to the USB standard.

On the other hand, the second driver is, for example, a driver that communicates with the device unit 50 via a wireless network such as wireless LAN or mobile communication network. In this case, the second communication method is Wi-Fi such as IEEE802.11a, IEEE802.11g, IEEE802.11ac, TCP/IP (Transmission Control Protocol/Internet Protocol), UDP (User Datagram Protocol), Bluetooth (registered trademark) , RoLa (or RoLaWAN), NB-IoT, LPWA (Low Power Wide Area) such as EnOcean, and MQTT (Message Queueing Telemetry Transport).

More specifically, the setting unit 12 is configured to set the first driver when attachment of the device unit 50 is detected, and to set the second driver when separation of the device unit 50 is detected. It is Thereby, the first driver and the second driver can be easily used properly when attaching and detaching the device unit 50 .

The receiving unit 13 is configured to receive the position information by positioning of the satellite positioning system from the device unit 50 using the set first driver or second driver.

The receiver 13 may be realized by the antenna 27 and the communication device 24 , for example, or may be realized by the processor 21 executing a program stored in the storage device 23 in addition to the communication device 24 . When executing a program, the program may be stored in a storage medium. The storage medium storing the program may be a non-transitory computer readable medium. The non-temporary storage medium is not particularly limited, but may be, for example, a storage medium such as a USB memory or a CD-ROM (Compact Disc ROM).

<Software architecture>
Next, referring to FIGS. 4 and 5, the software architecture (hereinafter also simply referred to as "architecture") of the terminal device and device unit according to the first embodiment will be described. FIG. 4 is a conceptual diagram showing the architecture of the terminal device 10 and the device unit 50 in the first embodiment. FIG. 5 is a conceptual diagram showing the architecture of the terminal device 10 and the device unit 50 in the first embodiment. 4 shows a state in which the device unit 50 is attached to the terminal device 10, and FIG. 5 shows a state in which the device unit 50 is separated from the terminal device 10. As shown in FIG.

As shown in FIGS. 4 and 5, the architecture of the terminal device 10 includes, for example, a kernel 31, a hardware abstraction layer (HAL) 32, an operating system (OS) 33, and an application 34. It has a hierarchical structure that includes

The kernel 31 provides drivers for devices such as displays, speakers, keyboards, cameras, USB devices, and Wi-Fi modules. The kernel 31 also includes the first and second drivers described above.

The hardware abstraction layer 32 is for abstracting hardware and exists between hardware and software. The hardware abstraction layer 32 has a function of hiding (invisible) differences that differ from hardware to hardware. Therefore, in the layers above the hardware abstraction layer 32, software can be designed and coded without being conscious of differences due to hardware. Of the detection unit 11, the setting unit 12, and the reception unit 13, at least the setting unit 12 is incorporated and implemented as a program of the hardware abstraction layer 32, for example.

Operating system 33 includes libraries such as, for example, native C libraries, native C++ libraries, runtime libraries, and frameworks that provide a framework for running applications. Also, the operating system 33 may include subroutines, classes, functions for using each application, APIs that summarize functions, and the like.

The applications 34 include, for example, applications installed in the terminal device 10 from the beginning, such as a call application, an email application, a camera application, a calendar application, and a map application.

The architecture of the device unit 50, like the terminal device 10, has a hierarchical structure including, for example, a kernel 41, a hardware abstraction layer 42, an operating system 43, and an application 44. FIG. Note that the kernel 41, the hardware abstraction layer 42, the operating system 43, and the application 44 are the same as the kernel 31, the hardware abstraction layer 32, the operating system 33, and the application 34, respectively. omitted.

Device unit 50 includes, for example, a GPS receiver (not shown), and application 44 uses GPS to determine the position of device unit 50 . A GPS receiver obtains position information from this position measurement.

As shown in FIG. 4, in a state where the device unit 50 is attached to the terminal device 10, the position information acquired by the receiver of the device unit 50 is transmitted by wire using the first communication method, which is a wired communication method. transmitted. In this case, the detection unit 11 of the terminal device 10 detects attachment of the device unit 50, and the setting unit 12 sets the first driver that communicates with the device unit 50 using the first communication method. Then, the receiving unit 13 receives the position information from the device unit 50 using the set first driver.

On the other hand, as shown in FIG. 5, in a state where the terminal device 10 is separated from the device unit 50, the position information acquired by the receiver of the device unit 50 is obtained by using the second communication method, which is a wireless communication method. It is transmitted wirelessly via the network NW. In this case, the detection unit 11 of the terminal device 10 detects separation of the device unit 50, and the setting unit 12 sets a second driver that communicates with the device unit 50 using the second communication method. Then, the receiving unit 13 receives the position information from the device unit 50 using the set second driver.

In this way, based on the detection result of attachment or detachment of the device unit 50, the first driver communicates with the device unit 50 using the first communication method, or the second driver uses the second communication method different from the first communication method. By setting a second driver that communicates with the device unit 50 via the API, the difference in communication with the device unit 50 that accompanies attachment and detachment of the device unit 50 can be handled as a correspondence between the device unit 50 that is hardware and the API. can be absorbed by the first and second drivers responsible for Therefore, the framework such as the operating system 33 and the application 34 are less modified than in the conventional case, and the separate use of the device unit 50 can be realized at a low cost.

Information acquired by the device unit 50 is not limited to the position information described above. The device unit 50 can acquire various information according to the type of device. The acquired information may be transmitted to the terminal device 10 in the same manner as the positional information. For example, the device unit 50 acquires acceleration from an acceleration sensor, and can calculate an approximate moving distance from the elapsed time and the acceleration. Moreover, the altitude can be calculated by acquiring the atmospheric pressure from the atmospheric pressure sensor. In addition, by acquiring changes in the tilt of the terminal from the gyro sensor, it is possible to determine the number of steps, motion, etc. of the user possessing the device unit 50 in combination with the acceleration sensor. The calculation logic can be held in the device unit 50 or the terminal device 10 . In addition, when the device unit 50 determines the number of steps or movement, the value of the number of steps is sent to the terminal device 10 . In addition, it is conceivable that by acquiring geomagnetic information from a geomagnetic sensor, the direction in which the terminal is facing can be known, and geomagnetic information is sent to the terminal device 10, and indoor positioning is performed from the geomagnetism by cooperation between the terminal device 10 and the server. be done. Also, by obtaining the scan results of Wi-Fi access points, such as BSSID, from the Wi-Fi module, it is possible to perform so-called Wi-Fi positioning in cooperation with the terminal device 10 and the server of the vendor providing the Wi-Fi positioning solution. can. In addition, by acquiring the sound from the microphone input and sending it to the terminal device 10, the terminal device 10 can use it to determine the situation of the device unit 50 side.

In the above examples, the terminal device 10 or the device unit 50 may directly calculate the distance traveled, the number of steps, etc. based on the values obtained from these devices, or the terminal device 10 may receive the values obtained from the device. Then, the data may be sent to a third-party server on the network NW, and the moving distance, the number of steps, etc. may be calculated on the server.

Also, the timing of sending the values obtained from these devices to the terminal device 10 may be the same timing as the position information described above, or may be sent separately. Alternatively, when GPS positioning cannot be performed for a certain period of time, the information necessary for Wi-Fi positioning is sent to the terminal device 10. If the value of the position information cannot be obtained from the GPS receiver, the value obtained from these devices can be used. may be sent. In addition, a method of instructing from the terminal device 10 which information is required, such as an inquiry from the device unit 50 by communication, a push from the terminal device 10, or the like, can also be adopted.

<Processing procedure>
Next, a processing procedure performed by the information communication system according to the first embodiment will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 is a time chart for explaining a first example of a processing procedure performed by the information communication system 100 according to the first embodiment. FIG. 7 is a time chart for explaining a second example of the processing procedure performed by the information communication system 100 in the first embodiment. 6 shows the case of separating the device unit 50 attached to the terminal device 10, and FIG. 7 shows the case of attaching the separated device unit 50 to the terminal device 10. FIG.

(Processing procedure of first example of information communication system)
As shown in FIG. 6, the detection unit 11 of the terminal device 10 detects attachment of the device unit 50 (S101). As described above, when the device unit 50 is attached to the USB, the detection unit 11 detects attachment of the device unit 50 based on whether USB enumeration is completed.

Next, since the attachment of the device unit 50 is detected, the setting unit 12 of the terminal device 10 sets the first driver that communicates with the device unit 50 using the first communication method (S102). The first driver is, for example, a USB driver that communicates via a USB connection line.

The device unit 50 performs positioning using, for example, a GPS receiver, and acquires position information of the device unit 50 from GPS satellites (S103). The location information is, for example, latitude and longitude information. In addition, the device unit 50 acquires location information regularly and/or irregularly. In addition to positioning using a GPS receiver, the device unit 50 performs positioning with a base station via, for example, Wi-Fi, a mobile communication network, Bluetooth (registered trademark), etc. location information may be acquired. This makes it possible to improve the accuracy of the position information of the device unit 50 .

Next, the device unit 50 transmits the acquired location information via USB, and the reception unit 13 of the terminal device 10 receives this location information using the first driver (S104). Thereby, the position information of the device unit 50 is communicated by wire.

Here, when the device unit 50 is removed from the terminal device 10, the detection unit 11 of the terminal device 10 detects separation of the device unit 50 (S105). As described above, when the device unit 50 is removed from the USB, the detection unit 11 determines whether the device unit 50 is detached based on whether a predetermined time has passed since the last communication after completion of USB enumeration. To detect.

Next, since the separation of the device unit 50 is detected, the setting unit 12 of the terminal device 10 sets a second driver that communicates with the device unit 50 using a second communication method different from the first communication method ( S106). The second driver is, for example, a Wi-Fi driver that communicates via a wireless LAN.

As in step S103, the device unit 50 performs positioning using the GPS receiver and acquires position information of the device unit 50 from GPS satellites (S107).

Next, the device unit 50 searches for nearby wireless LAN access points (hereinafter also simply referred to as "access points") and detects the access points (S108).

After step S108, the device unit 50 transmits the acquired location information via the wireless LAN, and the reception unit 13 of the terminal device 10 receives this location information using the second driver (S109). Thereby, the position information of the device unit 50 is communicated by wireless LAN (Wi-Fi).

On the other hand, as in step S107, the device unit 50 performs positioning using the GPS receiver, acquires the position information of the device unit 50 from GPS satellites (S110), and searches for access points in the vicinity. An access point may not be detected due to a change in location or a change in the communication environment such as an increase in signal strength (S111).

At this time, if a SIM (Subscriber Identity Module) card is inserted, the device unit 50 transmits the acquired location information via the mobile communication network, and the receiving unit 13 of the terminal device 10 activates the second driver. This location information is received by using (S112). Thereby, the location information of the device unit 50 is communicated by mobile (line provided by a mobile communication carrier).

(Processing procedure of the second example of the information communication system)
In the processing procedure of the second example below, the description of the content that overlaps with the processing procedure of the first example will be omitted as appropriate.

As shown in FIG. 7, the detection unit 11 of the terminal device 10 detects separation of the device unit 50 (S151). As described above, when the device unit 50 is separated from the USB, the detection unit 11 detects separation of the device unit 50 based on whether the USB bus driver detects connection with the device unit 50. .

Next, since the separation of the device unit 50 is detected, the setting unit 12 of the terminal device 10 sets a second driver that communicates with the device unit 50 using a second communication method different from the first communication method ( S152). The second driver is, for example, a Wi-Fi driver that communicates via a wireless LAN.

The device unit 50 performs positioning using the GPS receiver and acquires the position information of the device unit 50 from GPS satellites (S153).

Next, the device unit 50 searches for access points in the vicinity, but no access point can be detected here (S154). In this case, the device unit 50 transmits the acquired location information via the mobile communication network, and the receiving unit 13 of the terminal device 10 receives this location information using the second driver (S155). As a result, the location information of the device unit 50 is communicated via the line provided by the mobile communication carrier, that is, mobile communication.

On the other hand, as in step S153, the device unit 50 performs positioning using the GPS receiver and acquires the position information of the device unit 50 from GPS satellites (S156). Then, when the device unit 50 searches for access points in the vicinity, it may be possible to detect an access point due to a change in position due to movement or a change in the communication environment such as an increase in signal strength (S157).

In this case, the device unit 50 transmits the acquired location information via the wireless LAN, and the reception unit 13 of the terminal device 10 receives this location information using the second driver (S158). Thereby, the position information of the device unit 50 is communicated by wireless LAN (Wi-Fi).

Here, when the device unit 50 is attached to the terminal device 10, the detection unit 11 of the terminal device 10 detects attachment of the device unit 50 (S159). As described above, when the device unit 50 is attached to the USB, the detection unit 11 detects attachment of the device unit 50 based on whether USB enumeration is completed.

Next, since the attachment of the device unit 50 is detected, the setting unit 12 of the terminal device 10 sets the first driver that communicates with the device unit 50 using the first communication method (S160). The first driver is, for example, a USB driver that communicates via a USB connection line.

The device unit 50 performs positioning using, for example, a GPS receiver, and acquires position information of the device unit 50 from GPS satellites (S161).

Next, the device unit 50 transmits the acquired location information via USB, and the reception unit 13 of the terminal device 10 receives this location information using the first driver (S162). Thereby, the position information of the device unit 50 is communicated by wire.

In this way, the first communication method of the first driver relates to the wired communication method, and the second communication method of the second driver relates to the wireless communication method. Communication with the device unit 50 can be switched from wired communication to wireless communication when separated, and communication with the device unit 50 can be switched from wireless communication to wired communication when the separated device unit 50 is attached. be able to.

Further, by using the set first driver or second driver to receive position information from the device unit 50 based on the positioning of the satellite positioning system, when the device unit 50 is attached, the position information of the terminal device 10, which is the parent device, can be obtained. can be obtained, and when the device unit 50 is separated, the positional information of the device unit 50, which is a child device, can be obtained.

Although FIGS. 6 and 7 show an example in which the device unit 50 is physically attached to the USB, it is not limited to this. For example, the terminal device 10 may be set to operate as an access point, and the device unit 50 may be connected wirelessly to the terminal device 10 by tethering and logically attached. In this case, when searching for an access point of the terminal device 10, the device unit 50 connects to the terminal device 10 on the condition that the ESSID (Extended Service Set Identifier) matches and the BSSID (Basic Service Set Identifier) matches. You may make it In addition, the terminal device 10 may perform filtering based on the MAC address of the device unit 50 in order to strictly determine connection by the device unit 50 . Further, the device unit 50 may be wirelessly connected and logically attached to the terminal device 10 by Wi-Fi Direct or Bluetooth (registered trademark) instead of tethering.

(Processing procedure of terminal device)
Next, a processing procedure performed by the terminal device according to the first embodiment will be described with reference to FIG. FIG. 8 is a flowchart for explaining an example of information communication processing S200 performed by the terminal device 10 in the first embodiment.

As shown in FIG. 8, first, the detection unit 11 determines whether or not attachment of the device unit 50 has been detected (S201).

If the attachment of the device unit 50 is detected as a result of the determination in step S201, the setting unit 12 sets the first driver that communicates with the device unit 50 using the first communication method (S202).

On the other hand, if attachment of the device unit 50 is not detected as a result of the determination in step S201, the detection unit 11 determines whether separation of the device unit 50 has been detected (S203).

<Functional block configuration>
Next, the functional block configuration of the terminal device according to the second embodiment of the present invention will be described with reference to FIG. FIG. 10 is a configuration diagram showing an example of the functional block configuration of the terminal device 10A in the second embodiment. Note that FIG. 10 is intended to show the functional blocks required in this embodiment, and does not exclude that the terminal device 10A has functional blocks other than those shown.

As shown in FIG. 10, the terminal device 10A includes a detection unit 11A, a setting unit 12A, a logout unit 14, and a stop unit 15 as functional blocks. That is, the terminal device 10A is different from the terminal device 10 of the first embodiment in that it includes a logout section 14 and a stop section 15 instead of the receiving section shown in FIG.

The detection unit 11A is configured to detect login to the server 60 or logout from the server 60 .

For example, the terminal device 10A is configured to automatically attempt to log in to the server 60 during startup. Then, when the login to the server 60 is successful, the detection unit 11A detects login to the server 60 by receiving information indicating login success from the server 60, for example. On the other hand, for example, when the communication with the server 60 is cut off due to a change in the communication environment, the detection unit 11A detects logout from the server 60 because there is no communication with the server 60 for a predetermined time after login. Alternatively, for example, when logging out from the server 60 succeeds in accordance with a user's operation during login, the detecting unit 11A detects logout from the server 60 by receiving information indicating successful logout from the server 60, for example. do.

Based on the result of detection by the detection unit 11A, the setting unit 12A uses a first driver that communicates with the software of the terminal device 10A using the first communication method, or uses a second communication method different from the first communication method. It is configured to set up a second driver that communicates with the server 60 .

As in the first embodiment, the first driver and the second driver in the present embodiment are devices for controlling hardware included in the terminal device 10A or hardware connected to the terminal device 10A by the operating system. is the driver. However, in this embodiment, the first driver is for the operating system of the terminal device 10A to control the hardware of the terminal device 10A, and the second driver is for the operating system of the server 60 to control the hardware of the terminal device 10A. It is for controlling hardware.

The first driver is, for example, a driver that communicates with software of the terminal device 10A via a bus or the like of the terminal device 10A. In this case, the first communication method is a wired communication method according to serial transmission or the like.

On the other hand, the second driver is, for example, a driver that communicates with the server 60 via a wireless network such as a wireless LAN or mobile communication network, as in the first embodiment. In this case, the second communication method is a wireless communication method conforming to standards such as Wi-Fi, TCP/IP, Bluetooth (registered trademark), and LPWA.

More specifically, the setting unit 12A is configured to set the first driver when a logout from the server 60 is detected, and set the second driver when a login to the server 60 is detected. ing.

In this way, based on the result of detection of login to the server 60 or logout from the server 60, the first driver that communicates with the software of the terminal device 10A using the first communication method, or a different communication method from the first communication method. By setting a second driver that communicates with the server 60 using the second communication method, differences in communication in the terminal device 10A accompanying login to the server 60 and logout from the server 60 can be handled by hardware and API. It becomes possible to absorb by the first driver and the second driver which take charge of correspondence between them. Therefore, compared with the conventional technology, the framework such as the operating system 33 and the application 34 shown in FIGS. 4 and 5 need not be changed much, and the combined use of the thin client and the fat client of the terminal device 10A can be realized at low cost. .

The logout unit 14 is configured to logout from the server 60 based on at least one of the communication time with the server 60, the communication data amount with the server 60, and the area where communication with the server 60 is possible.

For example, the logout unit 14 logs out the terminal device 10A from the server 60 when the elapsed time after logging in to the server 60, that is, the communication time reaches a predetermined time or longer. Further, for example, the logout unit 14 logs out the terminal device 10A from the server 60 when the amount of communication data after logging in to the server 60 and starting communication reaches or exceeds a predetermined value. Furthermore, for example, when the terminal device 10A logged in to the server 60 moves out of the area where communication with the server 60 is possible, the logout unit 14 logs out the terminal device 10A from the server 60 . Whether or not the terminal device 10A has left the communicable area with the server 60 can be determined based on, for example, the radio signal strength, the positional information of the terminal device 10A, and the like. Note that the predetermined time to be compared with the communication time and the predetermined value to be compared with the amount of communication data may be set based on policy information described later.

In this way, by logging out of the server 60 based on at least one of the communication time with the server 60, the amount of communication data with the server 60, and the area in which communication with the server 60 is possible, according to a predetermined condition, The user can be forcibly logged out from the server 60, and the user does not need to perform an operation to log out from the server 60. - 特許庁

The stopping unit 15 is configured to disable part of the software of the terminal device 10A when logout from the server 60 is detected.

The software architecture of the terminal device 10A is the same as the software architecture of the terminal device 10A shown in FIGS. 4 and 5, and the software architecture of the server 60 is the same as the software architecture of the device unit 50 shown in FIGS. Or, since they are substantially the same, illustration and description thereof are omitted. Note that, of the detection unit 11A, the setting unit 12A, the logout unit 14, and the stopping unit 15, at least the setting unit 12A, as in the first embodiment, uses the hardware abstraction layer 32 shown in FIGS. is incorporated and implemented as a program of

<Processing procedure>
Next, a processing procedure performed by the information communication system according to the second embodiment will be described with reference to FIG. FIG. 11 is a time chart for explaining an example of a processing procedure performed by the information communication system 100A in the second embodiment.

(Processing procedure of information communication system)
As shown in FIG. 11, a policy is set by a user's operation, and the management device 70 transmits policy information indicating the policy to the server 60 (S181). Once the policy is set, management device 70 can update the policy. In this case, updated policy information is sent to the server 60 .

The policy information includes information regarding when the terminal device 10A logs out of the server 60. FIG. For example, the policy information includes geofence information indicating behavior when the terminal device 10A leaves a predetermined area, such as an airport or a hotel. Further, the policy information includes out-of-range information indicating the operation when the terminal device 10A leaves the area where communication with the server 60 is possible, and when the amount of communication data between the terminal device 10A and the server 60 reaches a predetermined limit value. Limit reaching time information indicating the operation, communication data limit value information indicating the predetermined limit value, lock screen text information indicating the text displayed on the lock screen when the terminal device 10A is locked, and the call function from the lock screen. Contains lock screen call enable/disable information indicating whether to enable or disable. Furthermore, the policy information may include retry information indicating the next retry timing when acquisition of the policy information fails.

The server 60 stores the received policy information in a storage device or the like (S182).

On the other hand, the terminal device 10A stores the default value of the policy information in the memory 22, the storage device 23, or the like, and sets synchronization timing in order to synchronize the value of the policy information stored in the server 60 (S183). . For the synchronization timing of the policy, for example, every predetermined time, every predetermined time, when logging in to the server 60, when the power of the terminal device 10A is turned on, specified date and time, and the like are set. The synchronization timing of the policy information may be set based on the user's operation of the terminal device 10A, or the server 60 may set the synchronization timing based on information transmitted from another device.

Here, for example, when the terminal device 10A moves into a communicable area with the server 60 and logs in to the server 60, the detection unit 11A of the terminal device 10A detects the login to the server 60 (S184).

Next, since login to the server 60 is detected, the setting unit 12A of the terminal device 10A sets a second driver that communicates with the server 60 using a second communication method different from the first communication method (S185). ). The second driver is, for example, a Wi-Fi driver that communicates via a wireless LAN.

Next, the terminal device 10A transmits a request for policy information to the server 60 (S186), and the server 60 reads the policy information stored in step S182 in response to this request, and sends the policy information to the terminal device 10A as a response. Send (S187). The terminal device 10A stores the received policy information in the storage device 23 or the like (S188). If the terminal device 10A stores policy information before step S188, the policy information is updated with the received policy information.

Note that the policy information may be encrypted by AES (Advanced Encryption Standard) or the like before being transmitted. Also, if the terminal device 10A fails to receive the response due to a communication error or the like, the policy information is not updated and remains as it was before the policy information was requested.

Here, for example, when the terminal device 10A leaves the predetermined area and logs out of the server 60, the detection unit 11A of the terminal device 10A detects the logout from the server 60 (S189).

Next, since logout from the server 60 is detected, the setting unit 12A of the terminal device 10A sets a first driver that communicates with the software of the terminal device 10A using the first communication method (S190).

Some software cannot be used (locked) S191
Next, the stopping unit 15 of the terminal device 10A disables part of the software of the terminal device 10A (S191). The software disabled by the deactivation unit 15 follows, for example, the policy information stored in step S188 described above.

In this way, by disabling part of the software of the terminal device 10A when a logout from the server 60 is detected, part of the functions can be disabled when the terminal device 10A is used as a fat client. can be restricted.

(Processing procedure of terminal device)

FIG. 12 is a flowchart for explaining an example of the information communication processing S250 performed by the terminal device 10A in the second embodiment.

As shown in FIG. 12, first, the detection unit 11A determines whether login to the server 60 has been detected (S251).

As a result of the determination in step S251, if login to the server 60 is detected, the setting unit 12A sets a second driver that communicates with the server 60 using a second communication method different from the first communication method (S252). . After step S252, the terminal device 10A terminates the information communication processing S250.

On the other hand, if the log-in to the server 60 is not detected as a result of the determination in step S251, the detection unit 11 determines whether log-out from the server 60 is detected (S253).

When logout from the server 60 is detected as a result of the determination in step S253, the setting unit 12A sets a first driver that communicates with the software of the terminal device 10A using the first communication method (S254).

On the other hand, as a result of the determination in step S253, if logout from the server 60 is not detected, the detection unit 11A returns to step S251, and performs steps S251 and S253 until login to the server 60 or logout from the server 60 is detected. repeat.

After step S254, the receiving unit 13 disables part of the software of the terminal device 10A by the stopping unit 15 (S255). After step S255, the terminal device 10A terminates the information communication processing S250.

It should be noted that the sequence and flowcharts described in this embodiment may be rearranged as long as there is no contradiction in processing.
