[0020] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to this embodiment, and in the following embodiments, the same components are designated by the same reference numerals, and redundant explanations will be omitted.

[0021] [First embodiment] The relationship between a wireless communication device and a reception-permitted area according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing the relationship between a wireless communication device and a reception-permitted area according to the first embodiment.

[0022] As shown in FIG. 1 , the wireless communication device 10 is capable of receiving signals within a predetermined reception-allowed area 1000 centered around, for example, the location of a base station or a set location. The wireless communication device 10 includes, for example, a transceiver, a smartphone, etc. The reception-allowed area 1000 is an area in which reception by the wireless communication device 10 is permitted. In this embodiment, the reception-allowed area 1000 is an area within a predetermined location range that allows reception but prevents reception outside the area to prevent eavesdropping by a stolen wireless communication device 10. The reception-allowed area 1000 is an area within a predetermined boundary (geofence). In the example shown in FIG. 1 , the reception-allowed area 1000 is a substantially circular area surrounding an area connecting multiple set points P. The reception-allowed area 1000 may also be a polygonal area connecting multiple set points P. The reception-allowed area 1000 is set by a user authenticated by administrator authority or a password, etc., operating the wireless communication device 10, and cannot be set by an ordinary user. For example, the permitted reception area 1000 can be set to a range with a radius of 5 km centered on the location of a police station.

[0023] For example, if the wireless communication device 10 is stolen, there is a possibility that communications may be intercepted by the wireless communication device 10 during the period until the theft is noticed. For this reason, the wireless communication device 10 requires authentication even for an authorized user to receive normally outside the reception-permitted area 1000. If the wireless communication device 10 moves to a position PE outside the reception-permitted area 1000, the wireless communication device 10 assumes that the device may have been stolen and requests authentication from the user. If authentication is not successful, the wireless communication device 10 is locked to restrict reception. In the following description, the wireless communication device 10 may be referred to as the "own device."

[0024] (Authentication of Wireless Communication Device) Although the following describes cases where the wireless communication device 10 uses a voiceprint at the time of transmission or a password as an authentication method, the authentication method is not limited to these. The wireless communication device 10 can use, for example, an authentication method that uses data on physical characteristics such as fingerprints, faces, irises, and veins, or an authentication method that uses data recorded or generated by another device.

[0025] The wireless communication device 10 has a predetermined grace period when it moves from inside to outside the reception-permitted area 1000. For example, if a user's voice is transmitted within the grace period, is not silent, and matches a pre-registered voiceprint, the wireless communication device 10 is authenticated as an authorized user and determined not to have been stolen. The grace period may be, for example, 10 minutes. This is based on the fact that a thief other than an authorized user will not transmit data and will only intercept communications so as not to detect that the wireless communication device 10 has been stolen. Within the grace period, the wireless communication device 10 remains capable of receiving data even when outside the reception-permitted area 1000. By using an authentication method based on the voiceprint of the transmitted voice, the wireless communication device 10 can eliminate the need for cumbersome operations such as entering a password. If no transmission by an authorized user occurs within the grace period, the wireless communication device 10 prompts the user to enter a password and performs authentication processing. When the grace period expires, the wireless communication device 10 is disabled for reception until authentication is successful using the entered password. In this way, when the wireless communication device 10 is outside the reception permission area 1000 and successfully authenticates the transmitted voice by voiceprint or password judgment, it expands the reception permission area 1000 to include a predetermined range based on the authentication position, and allows reception to continue while the device is located inside the expanded reception permission area 1000.

[0026] (Extended Reception Allowed Area) The wireless communication device 10 has a function of detecting the speed and distance of movement of the wireless communication device 10 based on its own location information. When the wireless communication device 10 moves outside the reception allowed area 1000 and authenticates the user as an authorized user, the wireless communication device 10 generates an extended area including the authenticated position of the wireless communication device 10 and sets (adds) it to the reception allowed area 1000 as a new reception allowed area 1000. In other words, if a transmission is made by an authorized user within a predetermined grace period, the wireless communication device 10 can automatically perform authentication without the user's knowledge, generate an extended area, and set a new reception allowed area 1000. The wireless communication device 10 determines the size of the extended area based on the distance of movement of the wireless communication device 10. For example, when a police vehicle is pursuing a suspicious vehicle, the wireless communication device 10 increases the area of ​​the extended area as the speed increases, thereby maintaining a constant frequency of requesting authentication from the user. An extended area is added each time the wireless communication device 10 is authenticated as an authorized user, and reception of communications is permitted in an area including all extended areas that do not meet the conditions for deleting an extended area, as described below.

[0027] An example of setting an extended area relative to a reception-allowed area will be described using FIGS. 2 to 4. FIGS. 2 to 4 are diagrams for explaining the relationship between the reception-allowed area and the extended area according to each embodiment. In FIGS. 2 to 4, a circular basic area 1100 determined by a predetermined radius R from a center position C is set as the initial reception-allowed area 1000. The basic area 1100 is a pre-set area in the wireless communication device 10 where communication reception is always possible. The reception-allowed area 1000 is composed of the basic area 1100 and an extended area. Points Pa to Pd indicate authentication points authenticated by the wireless communication device 10. For example, this indicates that transmission by an authorized user occurred between points Pa and Pd. Movement vectors Va to Vc are movement vectors of the wireless communication device 10 between points Pa and Pd, and indicate the distance (movement amount) and movement direction between the authentication points.

[0028] As shown in FIG. 2 , when the wireless communication device 10 is located at point Pa within the reception-allowed area 1000, which is the basic area 1100, the wireless communication device 10 can receive signals without any restrictions. Assume that the wireless communication device 10 authenticates the authorized user based on the transmitted voice at point Pa. The wireless communication device 10 then moves from the inside of the reception-allowed area 1000 to an outside point Pb, indicated by movement vector Va, using the mobile unit 100, and authenticates the authorized user based on the transmitted voice at point Pb (the authentication point). If the authentication is successful, the wireless communication device 10 sets an extended area 1200b, thereby setting the area including the basic area 1100 and the extended area 1200b as the extended reception-allowed area 1000. The extended area 1200b is a circle centered at point Pb and having a radius Rb corresponding to the speed of the moving mobile unit 100, and protrudes outside the basic area 1100. The extended area 1200b partially overlaps with the basic area 1100 and is smaller in area than the basic area 1100. This allows the wireless communication device 10 to continue reception while inside the extended reception-allowed area 1000.

[0029] As shown in FIG. 3 , following the state shown in FIG. 2 , the wireless communication device 10 moves from point Pb to point Pc outside the extended area 1200b using the mobile unit 100, as indicated by the movement vector Vb. At point Pc (the authentication point), the wireless communication device 10 authenticates the authorized user through the transmitted voice. If the authentication is successful, the wireless communication device 10 sets an extended area 1200c, thereby updating the area including the basic area 1100, the extended area 1200b, and the extended area 1200c as the extended reception allowed area 1000. The extended area 1200c is a circle centered at point Pc and has a radius Rc corresponding to the speed of the moving mobile unit 100, and protrudes outside the extended area 1200b. The extended area 1200c partially overlaps with the extended area 1200b and has a smaller area than the basic area 1100. This allows the wireless communication device 10 to continue reception while within the updated and extended reception allowed area 1000.

[0030] As shown in FIG. 4 , following the state shown in FIG. 3 , the wireless communication device 10 moves from point Pc to point Pd outside the expansion area 1200c using the mobile unit 100, as indicated by the movement vector Vc, and authenticates the authorized user at point Pd (authentication point) using the transmitted voice. The wireless communication device 10 then sets the expansion area 1200d, calculates the distance between point Pd (authentication point) and each of the previous authentication points, and determines whether the distance between point Pd (authentication point) and each of the previous authentication points is greater than or equal to a predetermined distance. In the example shown in FIG. 4 , the wireless communication device 10 determines that the distance between point Pd (authentication point) of the added expansion area 1200d and point Pb (authentication point), which is a previous authentication point, is greater than or equal to the predetermined distance, and deletes the expansion area 1200b. As a result, the wireless communication device 10 updates the basic area 1100, the expansion area 1200c, and the expansion area 1200d as the reception permission area 1000. The extension region 1200d is a circle Rd centered at point Pd and having a radius corresponding to the speed of the moving object 100, and protrudes outside the extension region 1200c. The extension region 1200d partially overlaps with the extension region 1200c and has a smaller area than the basic region 1100. In the following description, when it is not necessary to distinguish between the extension regions 1200b, 1200c, and 1200d, they will be simply referred to as the extension region 1200.

[0031] As described above, even if the wireless communication device 10 has the reception allowed area 1000 set to the basic area 1100 in the initial state, when the wireless communication device 10 moves outside the reception allowed area 1000, it authenticates whether the user is an authorized user, and if authenticated, adds the extended area 1200 to the reception allowed area 1000 in real time based on the location and amount of movement of the wireless communication device 10. As a result, every time the wireless communication device 10 is authenticated as an authorized user outside the basic area 1100, it can add an area determined based on the authenticated authentication point and the movement speed at the authentication point as the extended area 1200 to the reception allowed area 1000. As a result, the wireless communication device 10 can prevent unauthorized use in the event of theft or loss without interfering with use by authorized users.

[0032] Furthermore, when the distance between authentication points outside the basic area 1100 increases, the wireless communication device 10 deletes the previous extended area 1200 according to the amount of movement, so that the area of ​​the reception permission area 1000 is not unnecessarily expanded, and it is possible to prevent a decrease in the accuracy of theft detection. Furthermore, by determining the size of the extended area 1200 according to the amount of movement, for example, when a police vehicle is pursuing a suspicious vehicle, the area of ​​the extended area 1200 increases as the speed increases, thereby making it possible to keep the frequency of authentication requests constant.

[0033] In this embodiment, the wireless communication device 10 will be described as adding the extended area 1200 to the reception permission area 1000 as a setting method for the extended area 1200, but the present invention is not limited to this. For example, the wireless communication device 10 may use a setting method in which the wireless communication device 10 detects the direction of movement of the device itself and sets the extended area as an area in which the boundary of the extended area is partially deformed (protruded) in the direction of movement, for example, an elliptical shape.

[0034] (Configuration of wireless communication device) An example of the configuration of the wireless communication device 10 according to the first embodiment will be described using Fig. 5 and Fig. 6. Fig. 5 is a block diagram showing an example of the configuration of the wireless communication device according to the first embodiment.

[0043] The GNSS receiving unit 52 is configured with a GNSS receiver that receives GNSS signals from GNSS satellites, etc. The GNSS receiving unit 52 outputs the received GNSS signals to a position information acquiring unit 62 of the control unit 54. Note that the GNSS receiving unit 52 may be replaced with other devices, such as a GPS (Global Positioning System) receiver.

[0044] The control unit 54 controls each unit of the wireless communication device 10. The control unit 54 has, for example, an information processing device such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and a storage device such as a RAM or ROM. The control unit 54 executes a program that controls the operation of the wireless communication device 10 according to the present invention. The control unit 54 may be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 54 may be implemented by a combination of hardware and software. By executing the program, the control unit 54 executes a location information acquisition step, an authentication step, a storage step, an area management step, and a reception restriction step.

[0045] The control unit 54 includes a location information acquisition unit 62 , an authentication unit 64 , a region management unit 66 , and a reception restriction unit 68 as functional blocks realized by the processing performed by the control unit 54 .

[0046] The position information acquisition unit 62 detects position information D1 relating to the current position of the wireless communication device 10. The position information acquisition unit 62 acquires the position information D1 relating to the current position based on, for example, a GNSS signal received by the GNSS receiving unit 52. Note that the position information acquisition unit 62 may acquire the position information D1 from a GPS receiver.

[0047] The authentication unit 64 authenticates whether the user of the device is an authorized user. The authentication unit 64 authenticates whether the user is an authorized user based on input information from the operation unit 42 or the acquisition unit 44 and the registration information D4. The authentication unit 64 authenticates whether the user is an authorized user based on voiceprint information obtained from the user's voice acquired by the acquisition unit 44 and the registration information D4. If the current location information of the device is outside the reception-permitted area 1000 and voice is transmitted via the communication unit 40, the authentication unit 64 authenticates whether the user is an authorized user based on the voiceprint information of the authorized user registered in the registration information D4 and the voiceprint information of the transmitted voice. If authentication is not performed based on the transmitted voice for a predetermined time after the location information of the device is located outside the reception-permitted area 1000, the authentication unit 64 acquires a password via the operation unit 42 and authenticates whether the user is an authorized user based on the password registered in the registration information D4. The authentication unit 64 registers the authenticated location in the authentication location information D3 in the storage unit 50.

[0048] The area management unit 66 updates the information on the reception permission area 1000 that allows reception by the communication unit 40 to the latest information. The area management unit 66 adds or deletes the reception permission area 1000 stored in the storage unit 50. The area management unit 66 stores in the storage unit 50 permission area information D2 that indicates the reception permission area 1000 corresponding to the device itself. The area management unit 66 sets an extended area 1200, which is an area determined based on the authentication location where the authentication unit 64 authenticates the user as a legitimate user and the device's movement speed at the authentication location, in the reception permission area 1000 of the storage unit 50 every time authentication is performed outside the basic area 1100. In other words, every time authentication is performed outside the basic area 1100, the area management unit 66 adds the extended area 1200 to the reception permission area 1000 and stores it in the permission area information D2 of the storage unit 50. The area management unit 66 changes the permission area information D2 in the storage unit 50 so as to add or delete the extension area 1200 to or from the reception permission area 1000 indicated by the permission area information D2.

[0049] The region management unit 66 determines the size of the expansion region 1200 based on the moving speed of the wireless communication device 10 at the authentication point where authentication was successful. For example, when the speed is less than a predetermined speed, the region management unit 66 sets the radius of the expansion region 1200 to a basic radius r. When the speed is equal to or greater than the predetermined speed, the region management unit 66 multiplies the basic radius r by a coefficient K(v), which increases as the speed increases, to obtain a radius rv = K(v) × r. In this embodiment, the basic radius r is set to 500 m. In scene C1 shown in FIG. 6 , when authentication is successful while the wireless communication device 10 is stopped at a point Px outside the basic region 1100, the region management unit 66 determines an expansion region 1200 m with the basic radius r. In scene C2 shown in FIG. 6 , when authentication is successful while the wireless communication device 10 is moving at a speed equal to or greater than a predetermined speed at the point Px, the region management unit 66 determines an expansion region 1200 n with the radius rv. The expansion region 1200 n is larger than the expansion region 1200 m. In this embodiment, the area management unit 66 prevents the moving wireless communication device 10 from immediately leaving the expansion area 1200 by making the expansion area 1200 larger as the moving speed of the wireless communication device 10 increases.

[0050] The area management unit 66 shown in Figure 5 calculates the distance between the latest authentication point and the authentication point that was the basis for a previously added extended area 1200 included in the reception permission area 1000, and if there is a past authentication point where the distance between the authentication points is greater than a predetermined distance, it deletes the extended area 1200 that was added based on the past authentication point from the reception permission area 1000.

[0051] The reception restriction unit 68 restricts reception based on the current position information D1 of the device itself and the reception-permitted area 1000. The reception restriction unit 68 permits reception when the current position information D1 of the device itself is within the reception-permitted area 1000. The reception restriction unit 68 suppresses output of voice and data received by the communication unit 40 when the current position information D1 of the device itself is outside the reception-permitted area 1000.

[0052] (Processing Procedure of Wireless Communication Device) An example of the processing procedure of the wireless communication device 10 according to the first embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the processing procedure of the wireless communication device according to the first embodiment. The processing procedure shown in Fig. 7 is realized by the control unit 54 of the wireless communication device 10 executing a program.

[0053] The control unit 54 acquires the position information D1 and the moving speed of the own aircraft (step S10). For example, the control unit 54 acquires the position information D1 regarding the current position based on the GNSS signal received by the GNSS receiving unit 52, and calculates the moving speed from the past positions of the own aircraft, the current position, and the detection time, thereby acquiring the moving speed of the own aircraft.

[0054] The location information acquisition unit 62 determines whether or not it is outside the reception-allowed area 1000 (step S12). For example, if the location information D1 acquired in step S10 indicates a position outside the reception-allowed area 1000 indicated by the permission area information D2 in the storage unit 50, the location information acquisition unit 62 determines that it is outside the reception-allowed area 1000. If it is determined that it is outside the reception-allowed area 1000 (step S12; Yes), the process proceeds to step S14. If it is determined that it is not outside the reception-allowed area 1000 (step S12; No), the process proceeds to step S28.

[0055] The authentication unit 64 executes authentication processing by transmission (step S14). For example, by executing the authentication processing by transmission, if a voice is transmitted within a predetermined grace period, the voice is not silent, and the voice matches a pre-registered voiceprint, the authentication unit 64 authenticates the user as a legitimate user and not a theft. The authentication processing by transmission is an authentication processing that focuses on the behavior of thieves other than legitimate users, who do not transmit but only receive so as not to notice that the wireless communication device 10 has been stolen. Furthermore, authentication by transmission eliminates complicated operations such as entering a password, and does not interfere with the user's work. The predetermined grace period is set to a period, such as 10 minutes, for determining whether the wireless communication device 10 is being used by a legitimate user. If the predetermined grace period has elapsed, reception may be restricted (suppressed), and the suppression of reception may be lifted by authentication by entering a password. The authentication processing by transmission may be performed, for example, by attaching a fingerprint sensor to the PTT button, obtaining a user's fingerprint by pressing the PTT button with a finger when transmitting, and comparing the fingerprint with a registered fingerprint. The authentication process by transmission may be performed, for example, by taking a picture of the user's face with a camera when the PTT button is pressed and comparing the picture with registered facial feature information. The authentication unit 64 stores the current location of the device as the latest authentication location in the authentication location information D3 in the storage unit 50.

[0056] The authentication unit 64 determines whether or not to authenticate based on the determination result of step S14 (step S16). For example, the authentication unit 64 determines to authenticate if the authentication result indicates that the user is a legitimate user and authentication has been successful. The authentication unit 64 determines to authenticate if the authentication result indicates that the user is a legitimate user and authentication has been successful. If it is determined to authenticate (step S16; Yes), the process proceeds to step S18. If it is not determined to authenticate (step S16; No), the process proceeds to step S32.

[0057] If step S16 returns Yes, the region management unit 66 determines the latest expanded region 1200 to be added (step S18). For example, the region management unit 66 sets, as the expanded region 1200, a region determined based on the position information and moving speed acquired in step S10. In detail, the region management unit 66 sets, on the map, a circular region having the current position of the player's aircraft as its center and a radius corresponding to the moving speed as the expanded region 1200. The relationship between the moving speed and the radius of the expanded region 1200 is determined using, for example, a lookup table, a conversion program, or the like.

[0058] The area management unit 66 calculates the distance between the current authentication point and each of the past authentication points (step S20). For example, the area management unit 66 calculates the distance between the authentication points based on the latest authentication point, which is the current location of the device, and the past authentication points indicated by the authentication point information D3 in the storage unit 50. The area management unit 66 calculates the distance between the latest authentication point and an authentication point that was the basis of a previously added extended area 1200 included in the reception permission area 1000. If the authentication point information D3 indicates multiple past authentication points, the area management unit 66 calculates the distance from each of the multiple past authentication points to the latest authentication point.

[0059] The area management unit 66 determines the past expanded area 1200 to be deleted based on the distance between the authentication points (step S22). For example, if there is a past authentication point where the distance between the authentication points is equal to or greater than a predetermined distance, the area management unit 66 deletes the expanded area 1200 added based on the past authentication point from the reception permission area 1000. For example, in the example shown in FIG. 4, if the distance between the authentication points from the latest point Pd to the past point Pb is equal to or greater than a predetermined distance, the area management unit 66 deletes the expanded area 1200b added based on the past authentication point indicated by point Pb from the reception permission area 1000.

[0060] The area management unit 66 sets the reception permission area 1000 based on the determined extension area 1200 and basic area 1100 (step S24). For example, the area management unit 66 determines to add the latest extension area 1200 determined in step S18 to the reception permission area 1000, and determines to delete the previous extension area 1200 determined in step S22 from the reception permission area 1000. The area management unit 66 updates the reception permission area information D2 in the storage unit 50 with the reception permission area 1000 resulting from the addition or deletion of the extension area 1200.

[0061] The control unit 54 determines whether or not to terminate the process (step S26). For example, the control unit 54 determines to terminate the process when a termination condition is met, such as termination of use of the wireless communication device 10 or receipt of a termination request. If the control unit 54 determines not to terminate the process (step S26; No), the process returns to step S10, which has already been described, and continues the process. If the control unit 54 determines to terminate the process (step S26; Yes), the process shown in FIG. 7 is terminated.

[0062] If step S12 returns No, the authentication unit 64 executes authentication processing (step S28). For example, even if the device itself is located within the permitted reception area 1000, if no authorized user authentication has been performed since the device was started up (powered on), or if a predetermined time has passed since the last authentication, the authentication unit 64 performs authentication using various authentication methods such as voiceprint, fingerprint, password, or face. If a predetermined time has not passed since the last authentication processing was performed, the authentication unit 64 may skip the processing of step S28. The authentication unit 64 stores the current location of the device itself as the most recent authentication point in authentication point information D3 in the storage unit 50.

[0063] The authentication unit 64 determines whether the authenticated user is a legitimate user (step S30). If it is determined that the user is a legitimate user (step S30; Yes), the process proceeds to step S26. If it is not determined that the user is a legitimate user based on the authentication result (step S30; Yes), the process proceeds to step S32.

[0064] If step S30 returns No, the reception restriction unit 68 restricts reception by the communication unit 40 (step S32). For example, the reception restriction unit 68 restricts use of the device itself, preventing at least reception by the communication unit 40, thereby restricting communication. This allows the reception restriction unit 68 to prevent communications from being intercepted during the time it takes for an administrator, owner, or other person to notice that the device has been stolen. Note that restricting communications may also include disabling transmission and reception by the communication unit 40. In addition to restricting communications, the reception restriction unit 68 may also execute processing to lock the operation of the device itself or report the theft, loss, or the like via the communication unit 40. For example, by restricting only reception, the location information of the device itself can be transmitted without the thief noticing, thereby notifying other wireless communication devices 10 of the location of the stolen wireless communication device 10. The processing of FIG. 7 then ends.

[0065] As described above, in the first embodiment, the extended area is determined based on the location information and movement speed of the device itself. This allows the first embodiment to appropriately set the reception permission area, thereby preventing unauthorized use in the event of theft or loss.

[0066] Second Embodiment (Configuration of Wireless Communication Device) An example of the configuration of a wireless communication device according to a second embodiment will be described with reference to Fig. 8. Fig. 8 is a block diagram showing an example of the configuration of a wireless communication device according to the second embodiment.

[0067] The wireless communication device 10A differs from the wireless communication device 10 shown in FIG. 5 in that the storage unit 50 stores operation history information D5 and the control unit 54A includes an operation detection unit 70.

[0068] The storage unit 50 stores operation history information D5 indicating the history of operations detected on the wireless communication device 10A. The operation history information D5 is associated with information such as the location information of the wireless communication device 10A at the point where the operation was detected and the date and time when the operation was detected.

[0069] The area management unit 66A updates the information of the reception permission area 1000 that permits reception by the communication unit 40 to the latest information. The area management unit 66A sets an area determined based on the authentication location where the user is authenticated as a legitimate user by the authentication unit 64 and operation history information on the device itself at the authentication location as an extended area 1200 in the reception permission area 1000 of the storage unit 50 every time the user is authenticated outside the basic area 1100.

[0070] The area management unit 66A calculates the distance between the latest authentication point and the authentication point that was the basis for a previously added extended area 1200 included in the reception permission area 1000, and if there is a past authentication point where the distance between the authentication points is greater than a predetermined distance, it deletes the extended area 1200 that was added based on the past authentication point from the reception permission area 1000.

[0071] For example, the area management unit 66A determines an area determined based on the authentication point, operation history information D5 stored in the storage unit 50, and location information associated with the operation history information D5 as the extended area 1200. Specifically, for example, if a predetermined operation has been performed at the current location in the past, the area management unit 66A determines an area including the authentication point and the current location as the extended area 1200.

[0072] The operation detection unit 70 detects operation information indicating an operation on the wireless communication device 10. For example, the operation detection unit 70 associates the detected operation with the location information acquired by the location information acquisition unit 62 at the location where the operation was detected and the acquisition date and time, and stores the association in the storage unit 50 as operation history information D5.

[0073] The operation detection unit 70 detects, for example, a predetermined operation used by the area management unit 66 to set the extended area 1200, and stores the operation history information D5 in the storage unit 50. Examples of the predetermined operation include, but are not limited to, regular operations such as pressing the PTT button and changing the communication channel.

[0074] (Processing Contents of Wireless Communication Device) Processing contents of the wireless communication device according to the second embodiment will be described with reference to Fig. 9. Fig. 9 is a flowchart showing the flow of processing of the wireless communication device according to the second embodiment.

[0075] The position information acquisition unit 62 acquires the position information D1 of the own device (step S40). For example, the position information acquisition unit 62 acquires the position information D1 regarding the current position based on the GNSS signal received by the GNSS receiving unit 52, and stores the acquired position information D1 in the storage unit 50.

[0076] The processing from step S42 to step S46 is the same as the processing from step S12 to step S16 shown in FIG. 7, and therefore a description thereof will be omitted.

[0077] The area management unit 66A determines whether or not there is an operation history of a predetermined operation at the current position (step S48). For example, if the operation history information D5 stored in the storage unit 50 associates the current position with information indicating that a predetermined operation has been executed, the area management unit 66A determines that there is an operation history of the predetermined operation. If it is determined that there is an operation history of the predetermined operation (step S48; Yes), the process proceeds to step S50. If it is not determined that there is an operation history of the predetermined operation (step S48; No), the process proceeds to step S58.

[0078] If the determination in step S48 is Yes, the area management unit 66A determines the latest extended area 1200 to be added (step S50). Specifically, the area management unit 66 sets, as the extended area 1200, an area determined based on the authentication point, the predetermined operation associated with the authentication point indicated by the operation history information D5, and the position information acquired in step S40.

[0079] The processes from step S52 to step S64 are the same as the processes from step S20 to step S32 shown in FIG. 7, respectively, and therefore will not be described here.

[0080] As described above, in the second embodiment, the extended area is determined based on the location information of the device itself and the operation history information associated with the location information, and the reception allowed area is set. As a result, in the second embodiment, it is possible to appropriately set the reception allowed area when, for example, the device operates the PTT button and passes through a location where communication with other wireless communication devices is frequently performed.

[0081] [Modifications of the Second Embodiment] (First Modification) The area management unit 66A may determine, as the extended area, an area determined based on, for example, the authentication location where the authentication unit 64 authenticated the user as a legitimate user, the operation history information D5 stored in the storage unit 50, and the location information and time information associated with the operation history information D5. That is, the area management unit 66A may determine the extended area by taking into account the time information at which a predetermined operation was detected. For example, the area management unit 66A may set, on the map, a circular area centered on the current location of the device and a circular area centered on the location information associated with the operation history information D5 as the extended area 1200. Here, the circular area centered on the current location of the device or the location information associated with the operation history information D5, which is set as the extended area 1200, may be a predetermined area including the current location of the device or the location information associated with the operation history information D5. Furthermore, for example, if the current location of the device is included in a circular area on a map centered on the location information associated with the operation history information D5, the area management unit 66A may set the circular area centered on the location information associated with the operation history information D5 as the extended area 1200. For example, the area management unit 66A may identify multiple pieces of location information associated with the operation history information D5 on the map and set an area including circular areas centered on each piece of location information as the extended area 1200. The area management unit 66A may specify the relationship between a predetermined operation and the radius or size of the extended area 1200 using, for example, a lookup table or a conversion program. In this way, the area management unit 66A can take time information into account when specifying the extended area, thereby setting, for example, an area including the authentication point and a point where a predetermined operation was previously performed at the current time as the reception allowed area, thereby more appropriately setting the reception allowed area.

[0082] (Second Modification) The area management unit 66A may determine, as the extended area, an area determined based on, for example, the authentication location where the authentication unit 64 authenticated the authorized user and the location information associated with the operation history information D5 stored in the storage unit 50 within a predetermined time from the time the user was authenticated as the authorized user. For example, if there is a plurality of pieces of location information associated with the operation history information D5 stored in the storage unit 50 within a predetermined time from the time the user was authenticated as the authorized user, an area including a circular area centered on each piece of location information may be set as the extended area 1200. Here, the circular area centered on the current location of the device or the location information associated with the operation history information D5 set as the extended area 1200 may be a predetermined area including the current location of the device or the location information associated with the operation history information D5. This allows the area management unit 66A to set, as the reception permission area, an area including the authentication location and the location where a predetermined operation was performed within a predetermined time, thereby more appropriately setting the reception permission area.

[0083] (Third Modification) The area management unit 66A may determine, as the extended area, an area determined based on, for example, the authentication location where the authentication unit 64 authenticated the user as a legitimate user and, among the location information associated with the operation history information D5 stored in the storage unit 50, location information within a predetermined distance from the authentication location. For example, the extended area 1200 may be set to an area including a circular area centered on location information associated with the operation history information D5 stored in the storage unit 50 that is within a predetermined distance from the authentication location. Furthermore, for example, if there are multiple pieces of location information associated with the operation history information D5 stored in the storage unit 50 that are within a predetermined distance from the authentication location, the extended area 1200 may be set to an area including a circular area centered on each piece of location information. The extended area 1200 may be set to an area including a circular area centered on each piece of location information. Here, the circular area centered on the current location of the device or the location information associated with the operation history information D5 that is set as the extended area 1200 may be a predetermined area including the current location of the device or the location information associated with the operation history information D5. This allows the area management unit 66A to set the reception permission area to an area that includes the authentication point and a point where a specified operation was performed within a specified distance from the authentication point, thereby allowing for more appropriate setting of the reception permission area.

[0084] [Third embodiment] (Wireless communication device) An example of the configuration of a wireless communication device according to a third embodiment will be described with reference to Fig. 10. Fig. 10 is a block diagram showing an example of the configuration of a wireless communication device according to the third embodiment.

[0085] As shown in FIG. 10, the wireless communication device 10B differs from the wireless communication device 10A shown in FIG. 8 in that the memory unit 50 does not store operation history information D5 but stores radio wave intensity information D6, and in that the control unit 54B does not have an operation detection unit 70 but has a radio wave detection unit 72.

[0086] The radio wave intensity information D6 indicates the strength of radio waves received by the wireless communication device 10A from another wireless communication device. The received radio wave intensity is, for example, but not limited to, a received signal strength indicator (RSSI). The radio wave intensity information D6 is associated with information such as the location information of the wireless communication device 10A at the point where the radio waves were received and the date and time when the radio waves were received.

[0087] The radio wave detection unit 72 detects the radio wave intensity of radio waves received by the communication unit 40 from other wireless communication devices. The radio wave detection unit 72 generates radio wave intensity information D6, for example, by associating the location information acquired by the location information acquisition unit 62 with the radio wave intensity detected by the radio wave detection unit 72. The radio wave detection unit 72 may also generate the radio wave intensity information D6 by associating the information with information related to the date and time when the radio wave intensity was detected. The radio wave detection unit 72 stores the generated radio wave intensity information D6 in the storage unit 50.

[0088] (Processing Contents of Wireless Communication Device) Processing contents of the wireless communication device according to the third embodiment will be described with reference to Fig. 11. Fig. 11 is a flowchart showing the flow of processing of the wireless communication device according to the third embodiment.

[0089] The process of step S70 is the same as the process of step S40 shown in FIG. 9, and therefore a description thereof will be omitted.

[0090] The radio wave detection unit 72 detects the radio wave intensity when the device receives radio waves from another wireless communication device (step S72). Specifically, the radio wave detection unit 72 generates radio wave intensity information D6 by associating the detected radio wave intensity with the location information acquired in step S70, and stores the information in the storage unit 50.

[0091] The processes from step S74 to step S78 are the same as the processes from step S42 to step S46 shown in FIG. 9, respectively, and therefore will not be described here.

[0092] If step S78 returns Yes, the region management unit 66B determines the latest expansion region 1200 to be added (step S80). Specifically, the region management unit 66B sets the region determined based on the authentication point and the radio wave intensity information D6 at the authentication point as the expansion region 1200. For example, the region management unit 66B compares the radio wave intensity information D6 from before the predetermined time has elapsed with the latest radio wave intensity information D6 every time a predetermined time has elapsed, and if it determines that the radio wave intensity has increased, it narrows the expansion region 1200 by a predetermined amount. For example, the region management unit 66B compares the radio wave intensity information D6 from before the predetermined time has elapsed with the latest radio wave intensity information D6 every time a predetermined time has elapsed, and if it determines that the radio wave intensity has decreased, it widens the expansion region 1200 by a predetermined amount. For example, each time the region management unit 66B moves a predetermined distance, it compares the radio wave strength information D6 before the movement of the predetermined distance with the latest radio wave strength information D6, and if it determines that the radio wave strength has increased, it narrows the expansion region 1200 by a predetermined amount. For example, each time the region management unit 66B moves a predetermined distance, it compares the radio wave strength information D6 before the movement of the predetermined distance with the latest radio wave strength information D6, and if it determines that the radio wave strength has decreased, it widens the expansion region 1200 by a predetermined amount.

[0093] The processes from step S82 to step S94 are the same as the processes from step S52 to step S64 shown in FIG. 6, respectively, and therefore will not be described here.

[0094] As described above, in the third embodiment, the extended area is determined based on the radio wave strength when radio waves are received from other wireless communication devices, and the reception-allowed area is set. This makes it possible to appropriately set the reception-allowed area in accordance with, for example, changes in radio wave strength.

[0095] [Fourth embodiment] (Wireless communication device) An example of the configuration of a wireless communication device according to a fourth embodiment will be described with reference to Fig. 12. Fig. 12 is a block diagram showing an example of the configuration of a wireless communication device according to the fourth embodiment.

[0096] As shown in FIG. 12, the wireless communication device 10C differs from the wireless communication device 10A shown in FIG. 8 in that a control unit 54C does not include an operation detection unit 70 but includes an information generation unit 74.

[0097] The information generation unit 74 generates destination information by identifying a location or position information to which the wireless communication device 10C is to move. The information generation unit 74 generates destination information by identifying a location or position information to which the wireless communication device 10C is to move, for example, based on the content of communication between the wireless communication device 10C and another wireless communication device. The information generation unit 74 generates destination information by identifying a location or position information to which the wireless communication device 10C is to move, for example, based on the content of conversation included in an audio signal received by the communication unit 40 from another wireless communication device. The information generation unit 74 generates destination information by identifying a location or position information to which the wireless communication device 10C is to move, for example, based on the content of conversation included in an audio signal transmitted by the communication unit 40 to another wireless communication device.

[0098] The information generating unit 74, for example, performs a voice recognition process on the voice signal, and when a place name or address is detected, identifies the detected place name or address as the destination and generates destination information.

[0099] For example, when the information generation unit 74 receives text information from another wireless communication device, it performs character recognition processing on the text information, and if a place name or address is detected, it identifies the detected place name or address as a destination and generates destination information. Here, when the detected place name or address is identified as a destination, it is preferable to convert the information on the identified destination into location information using geocoding, a technology for converting location information into numerical values ​​such as latitude and longitude, and generate the destination information. This geocoding processing may be performed by the information generation unit 74, or the information generation unit 74 may communicate with an external server that performs geocoding processing and obtain the location information resulting from the geocoding processing.

[0100] (Processing Contents of Wireless Communication Device) Processing contents of the wireless communication device according to the fourth embodiment will be described with reference to Fig. 13. Fig. 13 is a flowchart showing the flow of processing of the wireless communication device according to the fourth embodiment.

[0101] The process of step S100 is the same as the process of step S40 shown in FIG. 9, and therefore a description thereof will be omitted.

[0102] The information generating unit 74 identifies the destination of the own device (step S102). Specifically, the information generating unit 74 identifies the destination based on the voice communication between the own device and the other wireless communication device, and generates destination information.

[0103] The process of step S104 is the same as the process of step S42 shown in FIG. 9, and therefore a description thereof will be omitted.

[0104] If the determination in step S104 is Yes, the authentication unit 64C executes the authentication process (step S106). For example, after the information generation unit 74 generates the destination information, the authentication unit 64C executes the authentication process based on a response from another wireless communication device.

[0105] The authentication unit 64C determines whether or not to authenticate (step S108). For example, when the authentication unit 64C receives a response from the other wireless communication device approving that its own device is heading to the destination, the authentication unit 64C determines that the user of the wireless communication device 10B is an authorized user and determines to authenticate the user. The response from the other wireless communication device may be voice or text. If it is determined to authenticate the user (step S108; Yes), the process proceeds to step S110. If it is not determined to authenticate the user (step S108; No), the process proceeds to step S124.

[0106] If step S108 returns Yes, the region management unit 66C determines the latest extended region 1200 to be added (step S110). The region management unit 66C determines, for example, an area determined based on the authentication point and destination information identified based on voice communication between the device itself and another wireless communication device as the extended region 1200. Specifically, the region management unit 66C determines the area surrounding the identified destination as the extended region 1200. Here, the area surrounding the destination may be a range of a circle with a predetermined radius centered on the identified destination information, or may be a predetermined area including the identified destination information.

[0107] The processes from step S112 to step S124 are the same as the processes from step S52 to step S34 shown in FIG. 9, respectively, and therefore will not be described here.

[0108] As described above, in the fourth embodiment, an extended area is determined in the area surrounding the identified destination, and a reception-allowed area is set. This makes it possible to appropriately set a reception-allowed area, for example, in the area surrounding the destination.

[0109] Fifth Embodiment (Wireless Communication Device) A configuration example of a wireless communication device according to a fifth embodiment will be described with reference to Fig. 14. Fig. 14 is a block diagram showing a configuration example of a wireless communication device according to the fifth embodiment.

[0110] As shown in FIG. 14, the wireless communication device 10D differs from the wireless communication device 10A shown in FIG. 8 in that it does not have a communication unit 40, but has a first communication unit 56 and a microphone 58, and in that the control unit 54D does not have an operation detection unit 70, but has an information generation unit 74D and an audio information acquisition unit 76.

[0111] The first communication unit 56 communicates with an external device using a predetermined first communication method, such as, but not limited to, a digital business radio communication method such as APCO-P25 or NXDN.

[0112] The microphone 58 collects audio around the wireless communication device 10D. The microphone 58 collects audio, for example, audio emitted by the user of the wireless communication device 10D or by external devices present around the wireless communication device 10D. The audio emitted by the external device may be audio emitted by an in-vehicle device, for example, when the user of the wireless communication device 10D is traveling in a vehicle. The audio emitted by the in-vehicle device may be, for example, a guidance audio emitted by a navigation device. The microphone 58 generates audio information of the collected audio. The microphone 58 may be configured as the acquisition unit 44.

[0113] The information generation unit 74D generates destination information by identifying a location or position information to which the wireless communication device 10D is to move. The information generation unit 74D generates destination information by identifying a location or position information to which the wireless communication device 10D is to move, for example, based on voice. The information generation unit 74D generates destination information by identifying a location or position information to which the wireless communication device 10D is to move, for example, based on voice information generated by the microphone 58. When a destination location is identified based on the voice information, the identified destination information may be converted into position information using geocoding, a technology for converting location information into numerical values ​​such as latitude and longitude, and the destination information may be generated. This geocoding process may be performed by the information generation unit 74D, or the information generation unit 74D may communicate with an external server that performs geocoding to obtain the position information resulting from the geocoding process.

[0114] The audio information acquisition unit 76 acquires audio information from the microphone 58. For example, the audio information acquisition unit 76 determines whether the audio picked up by the microphone 58 is audio emitted by an external device based on the acquired audio information. For example, the audio information acquisition unit 76 determines whether the audio picked up by the microphone 58 is audio emitted by an external device by comparing the acquired audio information with audio data indicating characteristics of audio emitted by external devices stored in the storage unit 50.

[0115] (Processing Contents of Wireless Communication Device) Processing contents of the wireless communication device according to the fifth embodiment will be described with reference to Fig. 15. Fig. 15 is a flowchart showing the flow of processing of the wireless communication device according to the fifth embodiment.

[0116] The process of step S130 is the same as the process of step S40 shown in FIG. 9, and therefore a description thereof will be omitted.

[0117] The audio information acquisition unit 76 determines whether audio information from the external device has been acquired (step S132). If it is determined that audio information from the external device has been acquired (step S132; Yes), the process proceeds to step S134. If it is not determined that audio information from the external device has been acquired (step S102; No), the process proceeds to step S150.

[0118] If the determination in step S132 is Yes, the information generation unit 74D identifies the destination of the own device (step S134). Specifically, the information generation unit 74D identifies the destination based on the sound generated by the external device and generates destination information.

[0119] The process of step S136 is the same as the process of step S42 shown in FIG. 9, and therefore a description thereof will be omitted.

[0120] If the determination in step S136 is Yes, the authentication unit 64D executes the authentication process (step S138). For example, after the information generation unit 74D generates the destination information, the authentication unit 64D executes the authentication process based on communication with another wireless communication device.

[0121] The authentication unit 64D determines whether to authenticate the wireless communication device 10D (step S140). For example, when the first communication unit 56 transmits the destination information generated by the information generation unit 74D to another wireless communication device, the authentication unit 64D determines that the user of the wireless communication device 10D is an authorized user and determines to authenticate the wireless communication device 10D. For example, when the authentication unit 64D receives a response from the other wireless communication device acknowledging that the wireless communication device 10D is heading to the destination, the authentication unit 64D determines that the user of the wireless communication device 10D is an authorized user and determines to authenticate the wireless communication device 10D. The response from the other wireless communication device may be voice or text. If it is determined that authentication is to be performed (step S140; Yes), the process proceeds to step S142. If it is not determined that authentication is to be performed (step S140; No), the process proceeds to step S156.

[0122] If step S140 returns Yes, the region management unit 66D determines the latest extended region 1200 to be added (step S142). The region management unit 66D determines, for example, an area determined based on the authentication point and destination information identified based on the audio generated by the external device as the extended region 1200. Specifically, the region management unit 66D determines the area surrounding the identified destination as the extended region 1200. Here, the area surrounding the destination may be a range of a circle with a predetermined radius centered on the identified destination information, or may be a predetermined area including the identified destination information.

[0123] The processes from step S144 to step S156 are the same as the processes from step S112 to step S124 shown in FIG. 13, respectively, and therefore will not be described again.

[0124] As described above, in the fifth embodiment, an extended area is determined in the area surrounding the destination identified based on the sound emitted by the external device, and a reception allowed area is set. This makes it possible to appropriately set a reception allowed area, for example, in the area surrounding the destination.

[0125] Sixth Embodiment (Wireless Communication Device) A configuration example of a wireless communication device according to a sixth embodiment will be described with reference to Fig. 16. Fig. 16 is a block diagram showing a configuration example of a wireless communication device according to the sixth embodiment.

[0126] As shown in FIG. 16, the wireless communication device 10E differs from the wireless communication device 10 shown in FIG. 5 in that it does not have a communication unit 40, but has a first communication unit 56 and a second communication unit 60, and in that a control unit 54E does not have an operation detection unit 70, but has an information generation unit 74E.

[0127] The second communication unit 60 communicates with an external device using a predetermined second communication method. For example, when the user of the wireless communication device 10E is traveling in a vehicle, the second communication unit 60 communicates with an in-vehicle device using the second communication method. The second communication unit 60 communicates with, for example, a navigation device 12 that provides route guidance using the second communication method. The navigation device 12 is a device that provides route guidance to a destination. The navigation device 12 may be, for example, installed in a vehicle or may be realized by a smartphone or the like. The second communication method may be, for example, a short-range wireless communication method such as Bluetooth (registered trademark), but is not limited to this.

[0128] The information generation unit 74E generates destination information by identifying a location or position information to which the wireless communication device 10E is to move. The information generation unit 74E generates destination information by identifying a location or position information to which the wireless communication device 10E is to move, for example, based on destination information indicating a destination input to the navigation device 12. Specifically, the information generation unit 74E acquires destination information from the navigation device 12, for example, via the second communication unit 60, and generates destination information by identifying a location or position information to which the wireless communication device 10E is to move, based on the acquired destination information. The information generation unit 74E may acquire route information indicating a route from the navigation device 12 to the destination, for example, via the second communication unit 60.

[0129] (Processing Contents of Wireless Communication Device) Processing contents of the wireless communication device according to the sixth embodiment will be described with reference to Fig. 17. Fig. 17 is a flowchart showing the flow of processing of the wireless communication device according to the sixth embodiment.

[0130] The process of step S160 is the same as the process of step S40 shown in FIG. 9, and therefore a description thereof will be omitted.

[0131] The information generation unit 74E determines whether or not destination information has been acquired from the navigation device 12 via the second communication unit 60 (step S162). If it is determined that destination information has been acquired (step S162; Yes), the process proceeds to step S164. If it is not determined that destination information has been acquired (step S162; No), the process proceeds to step S180.

[0132] If the determination in step S162 is Yes, the information generation unit 74E identifies a destination of the own vehicle (step S164). Specifically, the information generation unit 74E identifies the destination and generates destination information based on the destination information acquired from the navigation device 12.

[0133] The processes from step S166 to step S170 are the same as the processes from step S136 to step S140 shown in FIG. 15, respectively, and therefore will not be described again.

[0134] If step S170 returns Yes, the region management unit 66E determines the latest extended region 1200 to be added (step S172). The region management unit 66E determines, for example, an area determined based on the authentication point and destination information identified from the destination information as the extended region 1200. Specifically, the region management unit 66E determines, as the extended region 1200, an area surrounding the identified destination. For example, when the information generation unit 74E acquires route information from the navigation device 12, the region management unit 66E determines, as the extended region 1200, an area surrounding the route to the destination.

[0135] The processes from step S174 to step S186 are the same as the processes from step S144 to step S156 shown in FIG. 15, respectively, and therefore will not be described again.

[0136] As described above, in the sixth embodiment, an extended area is determined in the area surrounding a destination identified based on destination information acquired from a navigation device, and a reception-allowed area is set. This makes it possible to appropriately set a reception-allowed area in the area surrounding a destination, for example.

[0137] [Seventh embodiment] (Wireless communication device) A configuration example of a wireless communication device according to a seventh embodiment will be described with reference to Fig. 18. Fig. 18 is a block diagram showing a configuration example of a wireless communication device according to the seventh embodiment.

[0138] As shown in Figure 18, the wireless communication device 10F differs from the wireless communication device 10A shown in Figure 8 in that the memory unit 50 stores threshold information D7 and the control unit 54F does not have an operation detection unit 70 but does have a traffic information acquisition unit 78.

[0139] The threshold information D7 is information indicating a threshold value of a moving speed. For example, the threshold information D7 may associate the moving speed with position information. For example, the threshold information D7 may include information indicating a threshold value of an acceleration.

[0140] The traffic information acquisition unit 78 acquires traffic information about the travel route. The traffic information acquisition unit 78 acquires traffic information from an external server device, for example, via the communication unit 40. The traffic information includes various types of information about the travel route, such as congestion information, maximum speed information, and weather information about the travel route. The traffic information may also include information indicating the type of road, such as whether the travel route is an ordinary road or an expressway.

[0141] (Processing Contents of Wireless Communication Device) Processing contents of the wireless communication device according to the seventh embodiment will be described with reference to Fig. 19. Fig. 19 is a flowchart showing the flow of processing of the wireless communication device according to the seventh embodiment.

[0142] The position information acquisition unit 62 acquires the position information D1 and the movement speed of the own aircraft (step S190). For example, the position information acquisition unit 62 acquires the position information D1 regarding the current position based on the GNSS signal received by the GNSS receiving unit 52. For example, the position information acquisition unit 62 acquires the movement speed of the own aircraft by calculating the movement speed from the past positions of the own aircraft, the current position, and the detection time. The position information acquisition unit 62 associates the position information D1 with the movement speed and stores them in the storage unit 50.

[0143] The processes from step S192 to step S196 are the same as the processes from step S42 to step S46 shown in FIG. 9, respectively, and therefore will not be described here.

[0144] The region management unit 66F determines whether the moving speed of the host aircraft is equal to or less than a threshold value (step S198). Specifically, the region management unit 66F determines whether the moving speed of the host aircraft is equal to or less than a threshold value by comparing the threshold value information D7 stored in the storage unit 50 with the moving speed of the host aircraft acquired in step S190. If it is determined that the moving speed of the host aircraft is not equal to or less than the threshold value (step S198; No), the process proceeds to step S200. If it is determined that the moving speed of the host aircraft is equal to or less than the threshold value (step S198; Yes), the process proceeds to step S202.

[0145] If step S198 returns No, the region management unit 66F determines the latest extended region 1200 to be added and sets the range of the extended region to the normal range (step S200). Specifically, the region management unit 66F determines the extended region 1200 based on the authentication point and the moving speed, and sets the range of the extended region 1200 to the normal range. For example, the region management unit 66F may increase the size of the extended region 1200 the faster the moving speed. As a result, the faster the moving speed, the higher the possibility that the moving wireless communication device 10F will fall outside the extended region 1200. Therefore, by increasing the size of the extended region 1200 in accordance with the moving speed, it is possible to prevent the moving wireless communication device 10E from falling outside the extended region 1200.

[0146] If the determination in step S198 is Yes, the region management unit 66F determines the latest expansion region 1200 to be added and sets the range of the expansion region 1200 to be narrower than the normal range (step S202). That is, when the movement speed of the own device is equal to or lower than the threshold, the region management unit 66F narrows the range of the expansion region 1200 to be narrower than the normal range. This is because, when the movement speed of the own device is equal to or lower than the threshold, the expansion region 1200 is unlikely to deviate from the expansion region 1200 even if it is not widened, so there is no need to widen the expansion region 1200 more than necessary.

[0147] The processes from step S204 to step S216 are the same as the processes from step S32 to step S64 shown in FIG. 9, respectively, and therefore will not be described here.

[0148] That is, when the moving speed of the wireless communication device 10F is equal to or less than the threshold, the set reception permission area is smaller than when the moving speed of the wireless communication device 10F is not equal to or less than the threshold. This reduces the possibility that communications will be intercepted by an unauthorized user, for example, when the wireless communication device 10F is stolen.

[0149] As described above, in the seventh embodiment, when the moving speed of the wireless communication device is equal to or lower than a threshold, the range of the extended area is narrowed compared to the normal range, thereby making the reception permission area larger than necessary, and reducing the possibility that communications will be intercepted by an unauthorized user if the wireless communication device is stolen, for example.

[0150] [Modification of Seventh Embodiment] (Processing Contents of Wireless Communication Device) Processing contents of a wireless communication device according to a modification of the seventh embodiment will be described with reference to Fig. 20. Fig. 20 is a flowchart showing the flow of processing of a wireless communication device according to a modification of the seventh embodiment.

[0151] In a modification of the seventh embodiment, a process is performed in which the threshold value of the movement speed is changed in accordance with the movement speed of the player's own aircraft.

[0152] The process of step S220 is the same as the process of step S190 shown in FIG. 19, and therefore a description thereof will be omitted.

[0153] The traffic information acquisition unit 78 acquires traffic information about the area surrounding the route along which the vehicle is traveling (step S222).

[0154] The region management unit 66F changes the travel speed threshold based on the traffic information acquired by the traffic information acquisition unit 78 (step S224). For example, the region management unit 66F may increase the travel speed threshold when it is determined based on the traffic information that the travel route is an expressway. For example, the region management unit 66F may decrease the travel speed threshold when it is determined based on the traffic information that the travel route is congested. By changing the travel speed threshold based on the traffic information, the region management unit 66F can prevent the reception permission region from being set larger than necessary in accordance with the conditions of the travel route.

[0155] The processes from step S226 to step S250 are the same as the processes from step S192 to step S216 shown in FIG. 19, respectively, and therefore will not be described again.

[0156] As described above, in the modification of the seventh embodiment, the travel speed threshold for determining whether to narrow the size of the expanded area is changed based on traffic information about the travel route, thereby enabling the modification of the seventh embodiment to set the reception permission area more appropriately in accordance with the conditions of the travel route.

[0157] The components of each device shown in the figure are conceptual functional components and do not necessarily have to be physically configured as shown. In other words, the specific form of distribution and integration of each device is not limited to that shown, and all or part of the devices can be functionally or physically distributed and integrated in any unit depending on various loads, usage conditions, etc. Note that this distribution and integration configuration may also be performed dynamically.

Furthermore, the above-described components include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the so-called equivalent range.
