[Figure 8] FIG. 10 is a sequence diagram showing the process up to calling a user. DETAILED DESCRIPTION OF THE INVENTION

[0009] An example of the configuration of a calling system will be explained below using the following diagram. The calling system according to this embodiment is a system for efficiently calling users who are waiting for a seat or a person to be served in a predetermined facility such as a store, airport, station, or city hall.

[0010] The call system 1 of this embodiment includes, for example, a user information acquisition unit 2, a reception information acquisition unit 3, a recording unit 4, a location identification unit 5, a cancellation unit 6, a priority determination unit 7, and a call unit 8, as shown in FIG.

[0011] 2, the call system 1 has a typical computer hardware configuration including a processor 11 such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), internal memories such as RAM (Random Access Memory) or ROM (Read Only Memory), storage devices such as HDD (Hard Disk Drive) or SDD (Solid State Drive), an input / output I / F for connecting peripheral devices such as a display, and a communication I / F for communicating with devices external to the device. The call system 1 is configured as, for example, a server system, and the above-mentioned components may be connected to each other for communication wirelessly such as via Wifi (registered trademark).

[0012] The user information acquisition unit 2 is a specific example of a user information acquisition means. The user information acquisition unit 2 acquires user information including at least one of face information of a user who visits a predetermined facility and vehicle information of the user.

[0013] The user information acquisition unit 2 is composed of, for example, a camera 21 installed in a predetermined facility or in a parking lot attached to the facility, as shown in FIG. 3. The user information acquisition unit 2 recognizes facial information of users who visit the facility and information about the users' vehicles based on images captured by the camera 21. The facial information includes, for example, image information of faces. The vehicle information includes information on motorcycles, four-wheeled motor vehicles, bicycles, etc. The vehicle information includes, for example, vehicle license plates, parking numbers, bicycle information (color, size), and bicycle parking numbers. The user information acquisition unit 2 sequentially transmits the user information to the reception information acquisition unit 3.

[0014] The reception information acquisition unit 3 is a specific example of a reception information acquisition means. The reception information acquisition unit 3 acquires reception information when a user checks in at a predetermined facility.

[0015] Reception at a specified facility includes, for example, waiting for a seat when the user visits a store such as a restaurant, waiting for a seat on an airplane when the user visits a counter at an airport, or waiting for assistance when the user visits a store on mobile terminal 23.

[0016] The reception information includes, for example, information such as reception time, reception number, number of visitors, expected call time, and waiting time when the user checks in at a predetermined facility.

[0017] The reception information acquisition unit 3 is configured with, for example, a reception device 22 capable of performing reception operations at a predetermined facility, as shown in Fig. 3. The reception device 22 is provided with, for example, a touch panel, a camera, a printer, a sensor, and the like.

[0018] For example, when a user performs a reception operation, the reception information acquisition unit 3 uses a printer or the like to output a reception slip containing reception information and the like to the user. The user may have a mobile terminal 23 such as a smartphone. A QR code (registered trademark) or the like may be printed on the reception slip to allow the user to register with an application on the mobile terminal 23.

[0019] For example, the user downloads the application to the mobile terminal 23, and the application is set in the mobile terminal 23. The user can register their own reception information in the application by reading the QR code with the mobile terminal 23, and wait for a call.

[0020] The application on the mobile terminal 23 can manage the reception information on the reception slip. The mobile terminal 23 successively receives reception information from the reception information acquisition unit 3, and displays the waiting time and an automatic cancellation notice (described later), etc.

[0021] The recording unit 4 is a specific example of a recording means. The recording unit 4 records linked information in which the reception information acquired by the reception information acquisition unit 3 is linked with the user information acquired by the user information acquisition unit 2. The recording unit 4 may be implemented in the reception device 22, for example.

[0022] 4 is a diagram showing an example of the sequence of the reception process described above. As shown in FIG. 4, the camera 21 in the facility acquires facial information of a user who has visited the facility (S11). The camera 21 in the parking lot or the like acquires vehicle information of a user who has visited the facility (S12).

[0023] The user performs a reception operation such as waiting for a seat at the reception device 22 (S13). At that time, the recording unit 4 of the reception device 22 acquires the user's facial information from the cameras 21 in the facility (S14), acquires the user's vehicle information from the cameras 21 in the parking lot or the like (S15), compares the acquired facial information and vehicle information (camera information) with the facial information and vehicle information (reception information) of the user currently performing the reception (S16), and registers any matches as the above-mentioned linked information. The recording unit 4 of the reception device 22 performs processing to link the registered user's facial information and vehicle information with the reception number (S17), and registers them as linked information.

[0024] The reception device 22 prints out a reception slip (S18) on which is printed the registered reception number and a QR code for registration in the application on the mobile terminal 23. The user reads the QR code on the reception slip with the application on the mobile terminal 23 (S19), registers the reception information in the application, and waits until being called.

[0025] The position identification unit 5 is a specific example of a position identification means. The position identification unit 5 identifies the current position of the user based on the user association information in the recording unit 4. The position identification unit 5 may be implemented in the reception device 22, for example.

[0026] For example, the location determination unit 5 of the reception device 22 determines the current location of a user who is within a specified facility or a waiting range within a specified distance from the specified facility by comparing images taken by a camera 21 at a specified facility, parking lot, etc. with the user information in the user linking information.

[0027] 5, the user's portable terminal 23 estimates the current position of the user's portable terminal 23 based on GPS information received from a GPS satellite 24. The user's portable terminal 23 may transmit the current position of the user's portable terminal 23 to the position specifying unit 5 in response to a request from the position specifying unit 5. The user's portable terminal 23 may transmit the movement speed of the portable terminal 23 to the position specifying unit 5 together with the current position of the user's portable terminal 23.

[0028] The location identification unit 5 identifies the current location of a user who is outside the waiting range, that is at least a predetermined distance from a specified facility, based on the current location of the user's mobile terminal 23 transmitted from the user's mobile terminal 23 and the user linking information in the recording unit 4.

[0029] The cancellation unit 6 is a specific example of a cancellation means. The cancellation unit 6 may be implemented in, for example, the reception device 22. The cancellation unit 6 determines whether the user is outside the waiting range based on the current location of the user identified by the location identification unit 5.

[0030] When the cancellation unit 6 determines that the user is outside the waiting range, the cancellation unit 6 may automatically cancel the reception information of the user from the user linking information in the recording unit 4. When the user is outside the waiting range, the cancellation unit 6 may presume that the user will not be able to return to the specified facility at the expected call time, and may perform the cancellation.

[0031] In addition, when the cancellation unit 6 determines that the user is outside the waiting range, it may determine whether the user will be able to return to the specified facility at the call time based on the user's current location identified by the location identification unit 5 and the user's movement speed.

[0032] For example, the cancellation unit 6 estimates the distance between the user and the predetermined facility based on the user's current location, and estimates the arrival time for the user to reach the predetermined facility based on the estimated distance and the user's moving speed. Note that if the cancellation unit 6 cannot acquire the user's moving speed, it may instead acquire information about the user's means of transportation (car, bicycle, walking) and estimate the average speed of the acquired means of transportation as the user's moving speed. Then, based on the estimated arrival time, the cancellation unit 6 can determine whether the user will be able to return to the predetermined facility at the call time.

[0033] If the cancellation unit 6 determines that the user will be able to return to the predetermined facility at the estimated call time, the cancellation unit 6 may suspend the cancellation of the user's reception information.

[0034] 6 is a sequence diagram showing the processing when a user moves out of the range of the facility camera while waiting for a seat to become available. As shown in Fig. 6, the camera 21 in the facility sequentially acquires the user's face information and vehicle information (S21, S22) and transmits the acquired user's face information and vehicle information to the reception device 22.

[0035] If the reception device 22 is unable to acquire facial information and vehicle information that matches the registered facial information and vehicle information from the camera 21 within the facility (S23, S24), it instructs the mobile terminal 23 linked to the facial information and vehicle information that it was unable to acquire to send information about the current location and movement speed of the mobile terminal 23 (S25).

[0036] The cancellation unit 6 of the reception device 22 acquires the current location and movement speed of the mobile terminal 23 transmitted from the mobile terminal 23 (S26). Based on the acquired current location and movement speed, the cancellation unit 6 executes an automatic cancellation determination process by determining whether or not the user will be able to return to the specified facility by the expected call time (S27).

[0037] When the cancellation unit 6 determines that the reservation should be automatically canceled, it sends a cancellation notice to the mobile terminal 23 to inform the mobile terminal 23 that the reservation is subject to automatic cancellation (S28). The cancellation unit 6 sends the cancellation notice, for example, by sending an email or a message to the mobile terminal 23. This allows the user to confirm that the reservation is subject to automatic cancellation from the cancellation notice received by the mobile terminal 23.

[0038] The priority determination unit 7 is a specific example of a priority determination means. The priority determination unit 7 is implemented in, for example, the reception device 22. The priority determination unit 7 determines the priority when calling a user based on the current location of the user identified by the location identification unit 5 and the user association information in the recording unit 4.

[0039] 7 is a diagram showing three areas: a waiting area, an area outside the waiting area, and a facility camera area. The facility camera area is an area that can be photographed by a camera 21 installed in a predetermined facility.

[0040] The priority determination unit 7 determines the priority of calls to users registered in the linking information in the recording unit 4 based on the current location of the user identified by the location identification unit 5. The priority determination unit 7 determines in which of the above ranges the user is located based on the current location of the user identified by the location identification unit 5, and determines the priority of calls to that user.

[0041] For example, when the priority determination unit 7 determines that the user is within the facility camera range based on the user's current location identified by the location identification unit 5, the priority determination unit 7 determines the call priority of the user to be first. When the priority determination unit 7 determines that the user is outside the facility camera range but within the waiting range based on the user's current location identified by the location identification unit 5, the priority determination unit 7 determines the call priority of the user to be second.

[0042] If the priority determination unit 7 determines that the user is outside the waiting range based on the user's current location identified by the location identification unit 5, it determines the priority of the call for that user to be third. Note that if the determined priorities are the same, the priority determination unit 7 sets the priority of the user who accepted earlier as the higher priority.

[0043] The priority order determination unit 7 may execute the above-described process of determining the priority order of calls to a user at predetermined time intervals (for example, every 10 minutes).

[0044] The calling unit 8 is a specific example of a calling means. The calling unit 8 calls the user in accordance with the priority determined by the priority determining unit 7.

[0045] For example, when the calling unit 8 detects an empty seat in the facility using the facility camera 21 or the like, it calls the user in order of priority, starting with the user with the highest priority, according to the priority determined by the priority determination unit 7. The calling unit 8 calls the user by, for example, issuing a call notification, outputting a call voice, displaying a call, etc. to the user's mobile terminal 23. Note that the calling unit 8 may, for example, issue a call instruction to a person, who then calls the user.

[0046] 8 is a sequence diagram showing the process up to calling a user. The camera 21 in the facility acquires facial information of a user who has visited the facility (S31). The camera 21 in the parking lot or the like acquires vehicle information of a user who has visited the facility (S32). The recording unit 4 of the reception device 22 records the acquired user face information and vehicle information (S33, S34), and records linking information that links the acquired user face information and vehicle information to the reception information acquired by the reception information acquisition unit 3. The priority determination unit 7 performs the above-mentioned priority determination process based on the linking information in the recording unit 4 (S35), and determines the priority of the user's calls.

[0047] The calling unit 8 issues a call notification to the mobile terminal 23 of the user with the first priority in accordance with the priorities determined by the priority determination unit 7 (S36) and calls that user (S37). Thereafter, the calling unit 8 calls the users with the second, third, ... priorities in accordance with the priorities determined by the priority determination unit 7.

[0048] As described above, in the delivery management method according to this embodiment, the user information acquisition unit 2 acquires user information including at least one of facial information of a user who visits a predetermined facility and vehicle information of the user. The reception information acquisition unit 3 acquires reception information when the user checks in at the predetermined facility. The recording unit 4 records user linking information that links the reception information acquired by the reception information acquisition unit 3 with the user information acquired by the user information acquisition unit 2. The location identification unit 5 identifies the user's current location based on the user linking information in the recording unit 4. If the cancellation unit 6 determines, based on the user's current location identified by the location identification unit 5, that the user is away from the predetermined facility by a predetermined distance or more, the cancellation unit 6 cancels the user's reception information from the user linking information in the recording unit 4. The priority determination unit 7 determines a priority for calling the user based on the user's current location identified by the location identification unit 5 and the user linking information in the recording unit 4. The calling unit 8 calls the user according to the priority determined by the priority determination unit 7.

[0049] According to the delivery management method of this embodiment, if a user leaves the facility during a waiting time, the reception information of the user is automatically canceled and the priority of the user's call is determined, thereby making it possible to efficiently call users.
