DETAILED DESCRIPTION

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the illustrated examples.

[0015] <Configuration of the portable communication terminal control system 100>

[0016] Figure 1 and Figure 2 1 is a diagram showing the configuration of a portable communication terminal control system 100 according to the present embodiment.

[0017] like Figure 1 and Figure 2 As shown in FIG. 1 , the portable communication terminal control system 100 includes two first portable communication terminals 10A and 10B and a second portable communication terminal 20 .

[0018] The first portable communication terminal 10A, 10B and the second portable communication terminal 20 perform short-range wireless communication based on BLE (Bluetooth (registered trademark) Low Energy). Specifically, one of the first portable communication terminals 10A (a specific first portable communication terminal, a portable communication terminal) is a hub (a mother machine), and the other first portable communication terminal 10B and the second portable communication terminal 20 are peripheral devices (slave machines) to perform short-range wireless communication.

[0019] The first portable communication terminals 10A and 10B are, for example, smart watches worn and used by person A and person B who work as a team in a security service, etc. In the portable communication terminal control system 100 of this embodiment, it is assumed that the first portable communication terminal 10A (first smart watch) is worn by person A (one of the users), and the first portable communication terminal 10B (second smart watch) is worn by person B.

[0020] The second portable communication terminal 20 is a tablet terminal such as a handheld terminal or a smart phone, and is a terminal device used when person A and person B perform operations such as cash delivery in a team of two. In the portable communication terminal control system 100 of the present embodiment, the second portable communication terminal 20 is provided to be carried by person A. The second portable communication terminal 20 is installed with applications (application 1 and application 2; described later) used when performing operations such as cash delivery as described above. The application cannot be executed when person A and person B are not present, that is, when the first portable communication terminal 10A worn by person A and the first portable communication terminal 10B worn by person B are not within the range where short-range wireless communication based on BLE can be performed.

[0021] <Configuration of the first portable communication terminal>

[0022] Next, refer to Figure 3 The first mobile communication terminals 10A and 10B will be described.

[0023] Here, except that the first portable communication terminal 10A functions as a hub of short-range wireless communication based on BLE and the first portable communication terminal 10B functions as a peripheral device, the structure and operation of the first portable communication terminals 10A and 10B are roughly the same, so the first portable communication terminal 10A is used as a representative for explanation.

[0024] Figure 3It is a block diagram showing the functional configuration of the first mobile communication terminal 10A.

[0025] like Figure 3 As shown, the first mobile communication terminal 10A includes a CPU (Central Processing Unit) 11 , a RAM (Random Access Memory) 12 , a storage unit 13 , an operation unit 14 , a display unit 15 , a communication unit 16 , a timer unit 17 , and the like, and each unit is connected via a bus 18 .

[0026] The CPU (first portable communication terminal side determination unit (determination unit), transmission control unit) 11 is a processor that controls each unit of the first portable communication terminal 10A. The CPU 11 reads out a program stored in the storage unit 13 and expands the program to the RAM 12, and executes the program to perform various calculations. The CPU 11 (first processor) performs the first portable communication terminal side determination process (determination process), the transmission control process, and the display control process.

[0027] The RAM 12 provides a storage space for work to the CPU 11 and stores temporary data. The RAM 12 may also include a nonvolatile memory.

[0028] The storage unit 13 stores various data such as programs and setting data executed by the CPU 11. The programs are stored in the storage unit 13 in the form of computer-readable program codes. As the storage unit 13, a storage device that does not require power supply for data storage, such as a HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory can be used.

[0029] The setting data stored in the storage unit 13 includes identification data for identifying and specifying the first portable communication terminal 10B or the second portable communication terminal 20 as a target of the communication unit 16 to perform the short-range wireless communication based on BLE.

[0030] The operation unit 14 includes a button switch, a touch sensor provided on the display unit 15 , and the like, receives an input operation from a user, converts the operation content into an electric signal, and outputs the electric signal to the CPU 11 .

[0032] The communication unit 16 is a communication module having an antenna, a modulation / demodulation circuit, a signal processing circuit, etc., and performs wireless data communication with the communication unit 16 of the first portable communication terminal 10B or the communication unit 26 of the second portable communication terminal 20 according to the communication standard of short-range wireless communication based on BLE.

[0033] The timing unit 17 is configured to include, for example, a timer or a timing circuit, and measures the current time to acquire time information.

[0034] <Configuration of the Second Mobile Communication Terminal>

[0035] Figure 4 It is a block diagram showing the functional configuration of the second mobile communication terminal 20.

[0036] like Figure 4 As shown, the second mobile communication terminal 20 includes a CPU 21 , a RAM 22 , a storage unit 23 , an operation unit 24 , a display unit 25 , a communication unit 26 , and the like, and each unit is connected via a bus 27 .

[0037] The CPU (control unit, second portable communication terminal side determination unit) 21 is a processor that controls each unit of the second portable communication terminal 20. The CPU 21 reads a program (including the above-mentioned application program, etc.) stored in the storage unit 23 and expands the program to the RAM 22, and executes the program to perform various calculations. The CPU 21 (second processor) performs control processing and second portable communication terminal side determination processing.

[0038] The RAM 22 provides a storage space for work to the CPU 21 and stores temporary data. The RAM 22 may also include a nonvolatile memory.

[0039] The storage unit 23 stores various data such as programs and setting data executed by the CPU 21. The programs are stored in the storage unit 23 in the form of computer-readable program codes. As the storage unit 23, for example, a HDD, an SSD, a flash memory, etc. can be used.

[0040] The setting data stored in the storage unit 23 includes identification data for identifying and specifying the first portable communication terminal 10A as a target of the short-range wireless communication by the communication unit 26 using the BLE.

[0041] The operation unit 24 includes a button switch, a touch sensor provided on the display unit 25 , and the like, receives an input operation from a user, converts the operation content into an electric signal, and outputs the electric signal to the CPU 21 .

[0042] The display unit 25 is composed of an LCD, a CRT, etc., and performs screen display according to a display control signal from the CPU 21. In addition, the display screen of the display unit 25 is provided with the above-mentioned touch sensor, and functions as a touch panel type operation display unit.

[0043] The communication unit 26 is a communication module including an antenna, a modulation / demodulation circuit, a signal processing circuit, etc., and performs wireless data communication with the communication unit 16 of the first portable communication terminal 10A in accordance with the communication standard of short-range wireless communication based on BLE.

[0044] <Overview of the operation of the mobile communication terminal control system>

[0045] Next, refer to Figures 5 to 9C The operation of the portable communication terminal control system 100 will be described.

[0046] [State control processing]

[0047] Figure 5 This is a flowchart showing a state control process of the first mobile communication terminal 10A functioning as a hub in the short-distance wireless communication based on BLE.

[0048] like Figure 5 As shown, first, the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the first portable communication terminal 10B in the short-range wireless based on BLE has changed from the disconnected state to the established state (step S1). That is, in step S1, it is determined whether person A and person B have changed from a separated state to a state of being together (close state).

[0049] When it is determined in step S1 that the communication connection state with the first portable communication terminal 10B has shifted from the disconnected state to the established state (step S1; "yes"), the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the second portable communication terminal 20 in the short-range wireless based on BLE is already in the established state (step S2).

[0050] When it is determined in step S2 that the communication connection state with the second portable communication terminal 20 is already established (step S2; "Yes"), the CPU 11 of the first portable communication terminal 10A transmits a first release signal for releasing the execution restriction of all applications of the second portable communication terminal 20 to the second portable communication terminal 20 via the communication unit 16 (step S3). That is, the CPU 11 performs the first portable communication terminal side determination processing (determination processing) and the transmission control processing. Then, the CPU 11 of the first portable communication terminal 10A returns the processing to step S1 and repeats the subsequent processing.

[0051] When it is determined in step S2 that the communication connection state with the second portable communication terminal 20 is not established, that is, disconnected (step S2; No), the CPU 11 of the first portable communication terminal 10A returns the process to step S1 and repeats the subsequent processes.

[0052] In addition, when it is determined in step S1 that the communication connection state with the first portable communication terminal 10B has not been transferred from the disconnected state to the established state (step S1; "No"), the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the first portable communication terminal 10B is already in the established state (step S4).

[0053] When it is determined in step S4 that the communication connection state with the first portable communication terminal 10B is already established (step S4; "Yes"), the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the second portable communication terminal 20 has shifted from the disconnected state to the established state (step S5).

[0054] When it is determined in step S5 that the communication connection state with the second portable communication terminal 20 has shifted from the disconnected state to the established state (step S5; "Yes"), the CPU 11 of the first portable communication terminal 10A transmits a first release signal to the second portable communication terminal 20 via the communication unit 16 (step S3). Then, the CPU 11 of the first portable communication terminal 10A returns the process to step S1 and repeats the subsequent processes.

[0055] When it is determined in step S5 that the communication connection state with the second portable communication terminal 20 has not shifted from the disconnected state to the established state (step S5; No), the CPU 11 of the first portable communication terminal 10A returns the process to step S1 and repeats the subsequent processes.

[0056] In addition, when it is determined in step S4 that the communication connection state with the first portable communication terminal 10B is not an established state, that is, a disconnected state (step S4; "No"), the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the second portable communication terminal 20 has been transferred from the disconnected state to the established state (step S6).

[0057] When it is determined in step S6 that the communication connection state with the second portable communication terminal 20 has shifted from the disconnected state to the established state (step S6; "Yes"), the CPU 11 of the first portable communication terminal 10A transmits a second release signal for releasing the execution restriction of a part of the application programs of the second portable communication terminal 20 to the second portable communication terminal 20 via the communication unit 16 (step S7). Then, the CPU 11 of the first portable communication terminal 10A returns the process to step S1 and repeats the subsequent processes.

[0058] When it is determined in step S6 that the communication connection state with the second portable communication terminal 20 has not shifted from the disconnected state to the established state (step S6; No), the CPU 11 of the first portable communication terminal 10A returns the process to step S1 and repeats the subsequent processes.

[0059] [Display update processing]

[0060] Figure 6 This is a flowchart showing the display update process of the first portable communication terminal 10A. Fig. 7A 10A and 10B are diagrams showing an example of display styles of the display units 15 of the respective terminals when the first portable communication terminal 10A and the first portable communication terminal 10B transition to the established state. Figure 7B This is a diagram showing an example of the display style of the display unit 15 of each terminal when the first portable communication terminal 10A and the first portable communication terminal 10B shift to the disconnected state.

[0061] Note that the display update process is similarly performed in the first portable communication terminal 10B functioning as a peripheral device in the near-field wireless communication based on BLE, and therefore the display update process of the first portable communication terminal 10A will be described as a representative example.

[0062] like Figure 6 As shown, first, the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the first portable communication terminal 10B in the short-range wireless based on BLE has changed from the disconnected state to the established state (step S11). That is, in step S11, it is determined whether person A and person B have changed from the separated state to the gathered state.

[0063] If it is determined in step S11 that the communication connection state with the first mobile communication terminal 10B has shifted from the disconnected state to the established state (step S11; "Yes"), Fig. 7AAs shown, the CPU 11 of the first portable communication terminal 10A displays the fact that the connection has been established (e.g., text information "connecting to the BBBB terminal") on the display unit 15 of the first portable communication terminal 10A (step S12). That is, the CPU 11 performs display control processing. In addition, at this time, in the first portable communication terminal 10B, the fact that the connection has been established (e.g., text information "connecting to the AAAA terminal") is also displayed on the display unit 15 of the first portable communication terminal 10B. Here, "AAAA" displayed on the display unit 15 of each terminal is a name for identifying the first portable communication terminal 10A, and "BBBB" is a name (identification information) for identifying the first portable communication terminal 10B. In addition, at this time, the CPU 11 of the first portable communication terminal 10A reports the fact that the connection has been established by operating a vibration motor (not shown) provided by the first portable communication terminal 10A.

[0064] On the other hand, when it is determined in step S11 that the communication connection state with the first portable communication terminal 10B has not shifted from the disconnected state to the established state (step S11; No), the CPU 11 of the first portable communication terminal 10A skips step S12 and advances the processing to step S13.

[0065] Next, the CPU 11 of the first portable communication terminal 10A determines whether the communication connection state with the first portable communication terminal 10B in the BLE-based short-range wireless has changed from the established state to the disconnected state (step S13). That is, in step S13, it is determined whether person A and person B have changed from the state of being together to the state of being separated.

[0066] If it is determined in step S13 that the communication connection state with the first mobile communication terminal 10B has shifted from the established state to the disconnected state (step S13; "Yes"), Figure 7B As shown, the CPU 11 of the first portable communication terminal 10A displays the fact that the state has been transferred to the disconnected state (for example, a text message of "disconnecting with the BBBB terminal") on the display unit 15 of the first portable communication terminal 10A (step S14). In addition, at this time, in the first portable communication terminal 10B, the fact that the state has been transferred to the disconnected state (for example, a text message of "disconnecting with the AAAA terminal") is also displayed on the display unit 15 of the first portable communication terminal 10B. Then, the CPU 11 of the first portable communication terminal 10A returns the processing to step S11 and repeats the subsequent processing. In addition, at this time, the CPU 11 of the first portable communication terminal 10A may report the fact that the state has been transferred to the disconnected state by operating a vibration motor (not shown) of the first portable communication terminal 10A.

[0067] On the other hand, when it is determined in step S13 that the communication connection state with the first portable communication terminal 10B has not shifted from the established state to the disconnected state (step S13; No), the CPU 11 of the first portable communication terminal 10A returns the process to step S11 and repeats the subsequent processes.

[0068] [State transition processing]

[0069] Figure 8 This is a flowchart showing the state transition process of the second mobile communication terminal 20 functioning as a peripheral device in the short-distance wireless communication based on BLE. Fig.9A 2 is a diagram showing an example of a display mode of the display unit 25 of the second portable communication terminal 20 when the terminal 20 is shifted to the first release state. Fig. 9B 2 is a diagram showing an example of a display mode of the display unit 25 of the second portable communication terminal 20 when the second release state is shifted. Fig. 9C 1 is a diagram showing an example of the display mode of the display unit 25 of the second portable communication terminal 20 when the terminal 20 transitions to the locked state.

[0070] like Figure 8 As shown, first, the CPU 21 of the second portable communication terminal 20 determines whether the communication connection state with the first portable communication terminal 10A in the short-distance wireless communication based on BLE is in the established state (step S21).

[0071] When it is determined in step S21 that the communication connection with the first portable communication terminal 10A is established (step S21; YES), the CPU 21 of the second portable communication terminal 20 determines whether a first release signal has been received from the first portable communication terminal 10A via the communication unit 26 (step S22).

[0072] On the other hand, when it is determined in step S21 that the communication connection state with the first portable communication terminal 10A is not established, that is, is disconnected (step S21; "No"), the CPU 21 of the second portable communication terminal 20 returns the process to step S21 and repeats the subsequent processes.

[0073] When it is determined in step S22 that the first release signal has been received from the first portable communication terminal 10A (step S22; "Yes"), the CPU 21 of the second portable communication terminal 20 causes the terminal to transition to the first release state in which the execution restrictions on all applications of the terminal are released (step S23). Fig.9AAs shown, when the first release state is shifted, the start buttons B1, B2, B3, B4, ... for starting each application are displayed in an operable state on the display unit 25 of the second portable communication terminal 20. Here, among these applications, application (application) 1 and application (application) 2 are programs that process highly confidential information (for example, financial information or personal information, etc.), and are programs that require execution in a state where both person A and person B are present (security is required). In the first release state, application 1 and application 2 can be executed.

[0074] Then, the CPU 21 of the second mobile communication terminal 20 returns the process to step S21 and repeats the subsequent processes.

[0075] When it is determined in step S22 that the first release signal has not been received from the first portable communication terminal 10A (step S22; No), the CPU 21 of the second portable communication terminal 20 determines whether the second release signal has been received from the first portable communication terminal 10A via the communication unit 26 (step S24).

[0076] If it is determined in step S24 that the second release signal has been received from the first portable communication terminal 10A (step S24; "Yes"), the CPU 21 of the second portable communication terminal 20 changes the state of the terminal to the second release state (step S25). That is, the CPU 21 performs control processing and second portable communication terminal side determination processing. Fig. 9B As shown, when the second release state is shifted, the start buttons B1 and B2 for starting application 1 and application 2 of the respective applications are displayed in an inoperable state on the display unit 25 of the second portable communication terminal 20. That is, in the second release state, only applications other than application 1 and application 2, i.e., applications that are not required to be executed in a state where both person A and person B are present, can be executed.

[0077] Then, the CPU 21 of the second mobile communication terminal 20 returns the process to step S21 and repeats the subsequent processes.

[0078] In addition, when it is determined in step S24 that the second release signal has not been received from the first portable communication terminal 10A (step S24; "No"), the CPU 21 of the second portable communication terminal 20 determines whether the communication connection state with the first portable communication terminal 10A has shifted from the established state to the disconnected state (step S26).

[0079] When it is determined in step S26 that the communication connection state with the first portable communication terminal 10A has shifted from the established state to the disconnected state (step S26; "Yes"), the CPU 21 of the second portable communication terminal 20 shifts the state of the terminal to the locked state (step S27). Fig. 9C As shown, when the lock state is transferred, information indicating that the lock state is in progress (e.g., text information of "Terminal locked") is displayed on the display unit 25 of the second portable communication terminal 20, and the operation of starting each application cannot be performed. In addition, in the lock state, only incoming calls can be received and outgoing calls can be made to specific contact destinations.

[0080] Then, the CPU 21 of the second mobile communication terminal 20 returns the process to step S21 and repeats the subsequent processes.

[0081] When it is determined in step S26 that the communication connection state with the first portable communication terminal 10A has not shifted from the established state to the disconnected state (step S26; No), the CPU 21 of the second portable communication terminal 20 returns the process to step S21 and repeats the subsequent processes.

[0082] As shown above, the portable communication terminal control system 100 of the present embodiment comprises: a plurality of first portable communication terminals 10A, 10B, which include a specific first portable communication terminal 10A; and a second portable communication terminal 20, which transitions to any one of a restricted state in which an execution restriction is imposed on an application (a prescribed function) and a released state in which the restricted state is released, wherein in the portable communication terminal control system 100, the specific first portable communication terminal 10A distinguishes itself from each of the other first portable communication terminals 10B and the second portable communication terminal 20. The second portable communication terminal 20 determines whether the communication connection based on short-range wireless communication between the two terminals is in an established state. When it is determined that the communication connection with the other first portable communication terminal 10B is in an established state and when it is determined that the communication connection with the second portable communication terminal 20 is also in an established state, a release signal for transferring the second portable communication terminal 20 to a released state is sent to the second portable communication terminal 20. When the second portable communication terminal 20 receives the release signal from the specific first portable communication terminal 10A, the second portable communication terminal 20 transfers the second portable communication terminal 20 from the restricted state to the released state.

[0083] According to this configuration, the applications (application 1 and application 2) of the second portable communication terminal 20 can be executed only when person A wearing the first portable communication terminal 10A and person B wearing the first portable communication terminal 10B meet together and form a group of two, so that the work performed by person A and person B as a group can be thoroughly performed.

[0084] In addition, when the first portable communication terminal 10A determines that the communication connection with the other first portable communication terminal 10B is in the established state and that the communication connection with the second portable communication terminal 20 is also in the established state, the first portable communication terminal 10A sends a first release signal for causing the second portable communication terminal 20 to transition to the first release state to the second portable communication terminal 20. When it is determined that the communication connection with the other first portable communication terminal 10B is not in the established state and that the communication connection with the second portable communication terminal 20 is in the established state, the second portable communication terminal 20 sends a second release signal for causing the second portable communication terminal 20 to transition to the second release state to the second portable communication terminal 20. When the second portable communication terminal 20 receives the first release signal from the first portable communication terminal 10A, the second portable communication terminal 20 transitions to the first release state. When the second portable communication terminal 20 receives the second release signal from the first portable communication terminal 10A, the second portable communication terminal 20 transitions to the second release state.

[0085] According to this configuration, even when person A wearing the first portable communication terminal 10A and person B wearing the first portable communication terminal 10B are not present at the same time, if the communication connection between the first portable communication terminal 10A and the second portable communication terminal 20 is established, applications other than application 1 and application 2, that is, programs that do not require execution when person A and person B are present at the same time, can be executed, thereby improving the operability of the system.

[0086] The second portable communication terminal 20 determines whether the communication connection with the first portable communication terminal 10A is established, and if it is determined that the communication connection with the first portable communication terminal 10A is not established, the second portable communication terminal 20 is shifted from the released state to the restricted state.

[0087] Thus, when person A wearing the first portable communication terminal 10A leaves the location where the second portable communication terminal 20 is installed and the communication connection between the first portable communication terminal 10A and the second portable communication terminal 20 is disconnected, the application of the second portable communication terminal 20 cannot be executed.

[0088] Therefore, it is possible to prevent person B from executing the application program of the second portable communication terminal 20 alone or a third party from executing the application program, and thus it is possible to thoroughly perform the work that person A and person B perform as a team.

[0089] Furthermore, the description in the above embodiment is an example of the portable communication terminal control system of the present invention, but is not limited thereto.

[0090] For example, in the above-described embodiment, the second mobile communication terminal 20 is described as a terminal carried by person A, but the second mobile communication terminal 20 may be carried by person B.

[0091] In addition, in the above embodiment, it is assumed that person A and person B perform operations such as cash delivery in a group of two, but the target persons when performing the operation in a group may be more than three people. In this case, each target person carries a first portable communication terminal. Specifically, one of the target persons carries a first portable communication terminal that functions as a hub in BLE-based short-range wireless communication, and the target persons other than the one target person hold the first portable communication terminal that functions as a peripheral device. In addition, in this case, one of the above-mentioned target persons may carry a second portable communication terminal.

[0092] In addition, in the above-mentioned embodiment, as a condition for the first portable communication terminal 10A to send a release signal to the second portable communication terminal 20, it is set as a condition that the communication connection state between the first portable communication terminal 10A and the first portable communication terminal 10B is in an established state and the communication connection state between the first portable communication terminal 10A and the second portable communication terminal 20 is also in an established state, but it may also be possible to add the communication connection state between the first portable communication terminal 10A and a third portable communication terminal such as a smart phone carried by person B to be in an established state to the above-mentioned condition.

[0093] Furthermore, in the above-described embodiment, the execution of the application program stored in the storage unit 23 of the second portable communication terminal 20 is restricted, but the use of the second portable communication terminal 20 itself may be restricted.

[0094] Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-described embodiments, but includes a scope equivalent to the scope of the invention described in the claims.
