Description

[Technical Field]

[0001] The present disclosure relates to an information processing apparatus and a calling method. [Background Art]

[0002] An apartment house may not be provided with a calling device for calling a resident at a location such as the entrance on the first floor, for example. In this case, a visitor goes to the visited dwelling unit in the apartment house, and calls the resident by, for example, operating a calling device provided in front of the entrance.

[0003] Conventionally, an intercom system that enables a calling operation for a master unit of a dwelling unit using a mobile phone has been proposed (see Patent Document 1). [Prior Art Document] [Patent Document]

[0004] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2009-232421 [Summary of Invention] [Problem to be Solved by Invention]

[0005] If the visited resident is out, the visitor who has gone all the way to the dwelling unit in the apartment house ends up with a fruitless trip. This is especially the case when the dwelling unit is on an upper floor. Therefore, there is a demand for a device that allows a visitor to easily call the resident of the visited dwelling unit.

[0006] Non-limiting examples of the present disclosure contribute to providing an information processing apparatus and a calling method that allow a visitor to easily call the resident of a visited dwelling unit. [Means for Solving the Problem]

[0017] Hereinafter, embodiments of the present disclosure will be described in detail with appropriate reference to the drawings. However, excessive detailed description may be omitted in some cases. For example, detailed descriptions of already well-known matters and repeated descriptions for substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding for those skilled in the art.

[0018] It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims thereby.

[0019] <First Embodiment> <Overview of Calling System> FIG. 1 is a diagram for explaining an overview of a calling system according to the first embodiment. An apartment house 1 shown in FIG. 1 does not include a calling device for calling a resident of each dwelling unit at a predetermined location such as an entrance, for example. The apartment house 1 includes a calling device in each dwelling unit, for example.

[0020] The call device 2a shown in Figure 1 is installed in the apartment of resident A1 in apartment building 1. The call device 2a is an intercom that has, for example, a sub-unit installed in front of the entrance and a master unit installed inside the apartment that communicates with the sub-unit. The master unit is connected to a public network such as the internet and communicates with devices such as smartphones and mobile phones.

[0021] Terminal 2b is a device owned by resident A1 of apartment building 1. Terminal 2b is a device capable of making calls, such as a smartphone or mobile phone.

[0022] Furthermore, resident A1 of apartment building 1 only needs to be able to communicate with delivery person A2, so it is sufficient for them to have either the call device 2a or the terminal 2b. In the following, when the call device 2a and the terminal 2b are not distinguished, they may simply be referred to as terminal 2.

[0023] Identification image 3 is an image that contains (represents) identification information for identifying apartment building 1. Identification image 3 may also be a code image, such as a one-dimensional code or a two-dimensional code.

[0024] Identification image 3 is affixed (or installed) to the apartment building 1 or its surroundings. For example, identification image 3 is affixed to the exterior wall of apartment building 1, or to a designated structure such as a bulletin board installed on the premises of apartment building 1.

[0025] The identification information for identifying apartment building 1, represented by identification image 3, is associated with location information indicating the location of the apartment building in the information processing device described later. For example, location information such as the latitude and longitude of the apartment building is associated with the identification information in the information processing device.

[0026] Terminal 4 is a device carried by delivery person A2. Terminal 4 is a device capable of making calls, such as a smartphone or mobile phone. Terminal 4 is equipped with a location acquisition device, such as a GPS (Global Positioning System), to obtain the location of Terminal 4. Terminal 4 is also equipped with a reading device, such as a camera, to read the identification image 3.

[0027] Terminal 2 of resident A1 in apartment building 1 has an application (program) installed for operation in the call system. Resident A1 of apartment building 1, for example, operates terminal 2 to access the website of the service provider that provides the call system and downloads the call system application to terminal 2.

[0028] Terminal 4 of delivery person A2 will have applications installed, such as a web browser, for browsing websites.

[0029] <Configuration of the calling system> Figure 2 shows an example of the configuration of a calling system. In Figure 2, the same components as in Figure 1 are denoted by the same reference numerals.

[0030] As shown in Figure 2, the calling system comprises an information processing device 10 and terminals 2 and 4 as described in Figure 1. The information processing device 10 and terminals 2 and 4 communicate via a network N1 such as a wireless communication network like 3G, 4G, or 5G, and the Internet.

[0031] The information processing device 10 is a server. As described above, the information processing device 10 stores the identification information of apartment building 1 and the location information of apartment building 1 in association with each other. Furthermore, as will be described later, the information processing device 10 stores the room number of apartment building 1 and the identification information that identifies terminal 2 in association with each other (see Figure 6).

[0032] <Overview of the calling system's operation> Let me briefly explain how the calling system works. When delivery person A2 delivers a package to resident A1 of apartment building 1, they use the camera on terminal 4 to take an identification image 3. Terminal 4 transmits the identification information represented by the captured identification image 3 (identification information of apartment building 1) and the location information of terminal 4 to the information processing device 10.

[0033] The information processing device 10 determines whether terminal 4 is located within a certain range (within a certain distance) from apartment building 1, based on the location information of terminal 4 and the location information of apartment building 1 which is associated with the identification information of apartment building 1. In other words, the information processing device 10 determines whether delivery person A2, who is carrying terminal 4, is located within a certain range from apartment building 1.

[0034] If the information processing device 10 determines that terminal 4 is located within a certain range from apartment building 1, it displays a screen on terminal 4 for calling resident A1 of apartment building 1 (for example, a screen for entering the room number of apartment building 1) (see Figure 7). On the other hand, if the information processing device 10 determines that terminal 4 is not located within a certain range from apartment building 1, it displays a screen on terminal 4 indicating that it is not possible to call resident A1 of apartment building 1.

[0035] In other words, the information processing device 10 enables the summoning of resident A1 of the apartment building 1 when the terminal 4 is located near the apartment building 1. This prevents mischief such as the identification image 3 being moved to another location without permission, and resident A1 of the apartment building 1 being summoned from that location.

[0036] Delivery person A2 enters the room number of the recipient, resident A1, on the call screen displayed on terminal 4. Terminal 4 transmits the entered room number to the information processing device 10.

[0037] The information processing device 10 receives the room number entered at terminal 4. The information processing device 10 calls terminal 2 corresponding to the received room number. When terminal 2 responds, the information processing device 10 establishes a communication path between terminal 2 and terminal 4. The information processing device 10 establishes a communication path (data communication path) on a public network data line such as the Internet, rather than a voice call line of a mobile phone system such as 3GPP.

[0038] By establishing a communication channel between terminal 2 and terminal 4, delivery person A2, who possesses terminal 4, can communicate with resident A1, who possesses terminal 2. For example, delivery person A2 can inquire with resident A1 whether or not they are at home.

[0039] Through the above actions, delivery person A2 can easily call resident A1 of apartment building 1 using terminal 4, even in apartment building 1 where there is no call device in the entrance.

[0040] Furthermore, the calling system enables calling resident A1 of apartment building 1 when terminal 4 is located near apartment building 1. This allows resident A1 of apartment building 1 to be safely called by delivery person A2.

[0041] Furthermore, since delivery person A2 can easily call resident A1 of apartment building 1 using terminal 4, they can deliver the package only after confirming that resident A1 is home, thus reducing unnecessary effort. For example, if resident A1 is not home, the delivery person will not have to waste time calling the resident with the package and then returning to the delivery vehicle with the package.

[0042] Furthermore, since delivery person A2's terminal 4 communicates with terminal 2 using a data line, call costs can be reduced.

[0043] Furthermore, the calling system can be built by implementing an application on the terminal 2 of the residents of apartment building 1 and a browser on the terminal 4 of the delivery person A2, thus keeping initial costs down.

[0044] <Block diagram> Figure 3 shows an example of the block configuration of the information processing device 10. As shown in Figure 3, the information processing device 10 includes a control unit 10a, a storage unit 10b, and a communication unit 10c.

[0045] The control unit 10a controls the entire information processing device 10. The control unit 10a may be composed of, for example, a CPU (Central Processing Unit).

[0046] The memory unit 10b stores the program for the operation of the control unit 10a. The memory unit 10b also stores data for the control unit 10a to perform calculations and data for controlling the connected components. The memory unit 10b may be composed of storage devices such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, and HDD (Hard Disk Drive).

[0047] The communication unit 10c is connected to network N1 and communicates with devices connected to network N1.

[0048] Figure 4 shows an example of the block configuration of terminal 4. As shown in Figure 4, terminal 4 includes a control unit 4a, a storage unit 4b, a communication unit 4c, an audio processing unit 4d, a display 4e, an operation unit 4f, a camera 4g, and a position acquisition unit 4h.

[0049] The control unit 4a controls the entire terminal 4. The control unit 4a may be composed of, for example, a CPU.

[0050] The memory unit 4b stores the program for the operation of the control unit 4a. The memory unit 4b also stores data for the control unit 4a to perform calculations and data for controlling the connected components. The memory unit 4b may be composed of storage devices such as RAM, ROM, flash memory, and HDD.

[0051] The communication unit 4c is connected to network N1 and communicates with devices connected to network N1.

[0052] The audio processing unit 4d converts analog audio data output from the microphone (not shown) built into the terminal 4 into digital audio data and outputs it to the control unit 4a. The audio processing unit 4d also converts the digital audio data output from the control unit 4a into analog audio data and outputs it to the speaker (not shown) built into the terminal 4.

[0053] The display 4e displays images based on the digital video data output from the control unit 4a. The display 4e is, for example, a liquid crystal display.

[0054] The control unit 4f receives input from the owner of the terminal 4. The control unit 4f outputs information (signals) corresponding to the received input to the control unit 4a. The control unit 4f is, for example, a touch panel superimposed on the display 4e. The control unit 4f may also be a push button.

[0055] Camera 4g takes images according to the control of control unit 4a. Camera 4g outputs the captured image data to control unit 4a.

[0056] The position acquisition unit 4h receives, for example, a GPS signal and acquires the position of terminal 4 from the received GPS signal. The position acquisition unit 4h outputs the acquired position information of terminal 4 to the control unit 4a.

[0057] Since terminal 2b has the same block configuration as shown in Figure 4, its explanation will be omitted.

[0058] Figure 5 shows an example of the block configuration of the call device 2a. As shown in Figure 5, the call device 2a has a master unit 2a-1 and a slave unit 2a-2.

[0059] The master unit 2a-1 includes a control unit 2a-1a, a storage unit 2a-1b, a communication unit 2a-1c, an audio processing unit 2a-1d, a display 2a-1e, and an operation unit 2a-1f.

[0060] The control unit 2a-1a controls the entire master unit 2a-1. The control unit 2a-1a may be composed of, for example, a CPU.

[0061] The memory unit 2a-1b stores the program for the operation of the control unit 2a-1a. The memory unit 2a-1b also stores data for the control unit 2a-1a to perform calculations and data for controlling the connected units. Furthermore, the memory unit 2a-1b stores image data captured by the slave unit 2a-2. The memory unit 2a-1b may be composed of storage devices such as RAM, ROM, flash memory, and HDD.

[0062] The communication unit 2a-1c is connected to the slave unit 2a-2 by wire or wireless connection and communicates with the slave unit 2a-2. The communication unit 2a-1c is also connected to network N1 and communicates with devices connected to network N1.

[0063] The audio processing unit 2a-1d converts analog audio data output from a microphone (not shown) built into the master unit 2a-1 into digital audio data and outputs it to the control unit 2a-1a. The audio processing unit 2a-1d also converts the digital audio data output from the control unit 2a-1a into analog audio data and outputs it to a speaker (not shown) built into the master unit 2a-1.

[0064] The display 2a-1e displays images based on digital video data output from the control unit 2a-1a. The display 2a-1e is, for example, a liquid crystal display.

[0065] The control unit 2a-1f receives operations from residents of the dwelling unit where the master unit 2a-1 is installed. The control unit 2a-1f outputs information corresponding to the received operation to the control unit 2a-1a. The control unit 2a-1f may be, for example, a touch panel superimposed on the display 2a-1e. Alternatively, the control unit 2a-1f may be a push button or the like.

[0066] The slave unit 2a-2 includes a control unit 2a-2a, a storage unit 2a-2b, a communication unit 2a-2c, an audio processing unit 2a-2d, an operation unit 2a-2e, and a camera 2a-2f.

[0067] The control unit 2a-2a controls the entire slave unit 2a-2. The control unit 2a-2a may be composed of, for example, a CPU.

[0068] The memory units 2a-2b store programs for the operation of the control units 2a-2a. The memory units 2a-2b also store data for the control units 2a-2a to perform calculations and data for controlling the connected units. The memory units 2a-2b may be composed of storage devices such as RAM, ROM, flash memory, and HDD.

[0069] The communication units 2a-2c are connected to the master unit 2a-1 by wire or wireless connection and communicate with the master unit 2a-1.

[0070] The audio processing unit 2a-2d converts analog audio data output from the microphone (not shown) built into the slave unit 2a-2 into digital audio data and outputs it to the control unit 2a-2a. The audio processing unit 2a-2d also converts the digital audio data output from the control unit 2a-2a into analog audio data and outputs it to the speaker (not shown) built into the slave unit 2a-2.

[0071] The operation units 2a-2e receive operations from visitors. The operation units 2a-2e output information corresponding to the received operations to the control unit 2a-2a.

[0072] Cameras 2a-2f photograph the area in front of the slave unit 2a-2 in accordance with the control unit 2a-2a. For example, camera 2a-2f photographs a visitor who operates the control unit 2a-2e. Camera 2a-2f outputs the captured image data to the control unit 2a-2a.

[0073] <Example Data Structure> Figure 6 shows an example of the data configuration stored in the storage unit 10b of the information processing device 10. As shown in Figure 6, the storage unit 10b of the information processing device 10 stores the property management ID, property name, property location information, room number, resident terminal type, and resident terminal ID.

[0074] The property management ID, property name, and property location information shown in Figure 6 are stored in the storage unit 10b, for example, when the manager or owner of an apartment building introduces the call system service to the apartment building.

[0075] When a building manager or owner introduces a call system service, they will, for example, notify the residents of the building that the call system service has been introduced. Residents who wish to use the call system service access the website of the service provider and download the call system application to their terminal. The room number and resident terminal type shown in Figure 6 are registered by the residents of the building who have downloaded the application.

[0076] The property management ID is identification information used to identify apartment buildings. The property management ID is, for example, digitized as a one-dimensional or two-dimensional code and affixed to the apartment building (see identification image 3 in Figure 1).

[0077] The property name is the name of the apartment building corresponding to the property management ID.

[0078] Property location information refers to the location of the apartment building corresponding to the property management ID. Property location information is indicated, for example, by latitude and longitude.

[0079] The room number is the room number of the resident who downloaded the call system application to their terminal. For example, a resident who has downloaded the call system application registers their room number in the apartment building with the call system according to the instructions in the downloaded application.

[0080] The resident terminal type refers to the type (model) of the terminal used by the resident to receive calls from delivery personnel. For example, a resident who has downloaded the call system application will register the type (model) of the terminal used to receive calls from delivery personnel with the call system according to the downloaded application.

[0081] For example, a resident who has downloaded the call system application and wants to receive calls from delivery personnel via their smartphone registers their smartphone with the call system. Similarly, a resident who has downloaded the call system application and wants to receive calls from delivery personnel via their intercom registers their intercom with the call system. A resident may register multiple devices with the call system.

[0082] The resident terminal ID is identification information assigned to the terminal type registered by the resident. The resident terminal ID is assigned by the information processing device 10 when the resident registers the terminal type with the calling system. The information processing device 10 then calls the resident's terminal using the resident terminal ID. The resident terminal ID may be, for example, a push ID.

[0083] Note that the data shown in Figure 6 does not necessarily have to be stored in the storage unit 10b of the information processing device 10. The data shown in Figure 6 may be stored in another information processing device, such as a storage server connected to the network N1. Hereafter, the data shown in Figure 6 may be referred to as the retrieved data.

[0084] <Screen example> When delivery person A2 calls resident A1 of apartment building 1, they use terminal 4 to take a picture of the identification image 3 attached to apartment building 1. Terminal 4 transmits the identification information (property management ID) represented by the captured identification image 3 and the location information of terminal 4 to information processing device 10.

[0085] When the information processing device 10 receives identification information represented by the identification image 3 and location information of the terminal 4 from the terminal 4, it refers to the call data stored in the storage unit 10b based on the received identification information and obtains the property location information of the apartment building 1.

[0086] The information processing device 10 determines whether terminal 4 is located within a certain range from apartment building 1, based on the acquired property location information of apartment building 1 and the location information received from terminal 4.

[0087] If the information processing device 10 determines that terminal 4 is not located within a certain range from apartment building 1, it displays a screen on terminal 4's display indicating that it cannot call resident A1 of apartment building 1. If the information processing device 10 determines that terminal 4 is located within a certain range from apartment building 1, it displays a screen on terminal 4's display for calling resident A1 of apartment building 1.

[0088] Figure 7 shows an example of a screen displayed on the terminal 4's display. Screen A7a in Figure 7 is displayed when delivery person A2 takes an identification image 3 of the apartment building 1 using terminal 4 and terminal 4 is located within a certain range of the apartment building 1.

[0089] As shown in screen A7a, the name of apartment building 1, from which the identification image 3 was taken by delivery person A2, is displayed on the display of terminal 4 held by delivery person A2. In addition, a key image for entering the room number of a resident of apartment building 1 is displayed on the display of terminal 4 held by delivery person A2. Delivery person A2 enters the room number of resident A1 of apartment building 1, that is, the room number of the resident to be delivered, into terminal 4 and presses (tap) the "Call" button.

[0090] When the “Call” button is tapped, terminal 4 uses its camera to photograph the owner of terminal 4, i.e., delivery person A2. Terminal 4 transmits the captured image, such as the facial image of delivery person A2, to the information processing device 10. The information processing device 10 transmits the received image to the terminal that delivery person A2 called. The image captured by terminal 4's camera may be a video or a still image.

[0091] Figure 8 shows an example of a screen displayed on the terminal 4's display. For example, when the “Call” button shown on screen A7a in Figure 7 is tapped, screen A8a shown in Figure 8 is displayed on the terminal 4's display. As shown on screen A8a, the display of terminal 4, held by delivery person A2, shows a call in progress screen. The display of terminal 4 shows the name of apartment building 1 and the room number of resident A1, who was called by delivery person A2.

[0092] Figure 9 shows an example of a screen displayed on terminal 2b. For example, when the “Call” button shown on screen A7a in Figure 7 is tapped, screen A9a shown in Figure 9 is displayed on the display of terminal 2b, which is held by resident A1 of apartment building 1. The display of terminal 2b shows the camera image from the terminal 4 of the person who called resident A1 of apartment building 1, i.e., the terminal 4 of delivery person A2.

[0093] Resident A1, who possesses terminal 2b, looks at the camera image displayed on terminal 2b's screen and taps either the "Answer" button or the "Reject" button. For example, if the camera image displayed on terminal 2b's screen is of a delivery person, resident A1 taps the "Answer" button.

[0094] In this way, the camera image of the person making the call is displayed on terminal 2b's screen. This allows the owner of terminal 2b to see the camera image of the person making the call displayed on terminal 2b's screen and decide whether to answer or reject the call.

[0095] Figure 10 shows an example of a screen displayed on the call device 2a. For example, when the “Call” button shown on screen A7a in Figure 7 is tapped, screen A10a shown in Figure 10 is displayed on the call device 2a installed in the apartment of resident A1 of apartment building 1. The call device 2a's display shows a camera image of the person who called resident A1 of apartment building 1.

[0096] Resident A1, who has a call device 2a installed in their dwelling unit, looks at the camera image displayed on the call device 2a's screen and taps either the "Answer" button or the "Reject" button. For example, if the camera image displayed on the call device 2a's screen is of a delivery person, A1 taps the "Answer" button.

[0097] In this way, the camera image of the person making the call is displayed on the display of the call device 2a. This allows resident A1, who has the call device 2a in their dwelling unit, to see the camera image of the person making the call displayed on the display of the call device 2a and decide whether to respond to or reject the call.

[0098] <Sequence> Figures 11 and 12 are sequence diagrams illustrating an example of the operation of the call system. The sequence in Figure 12 continues at the circled numbers shown in Figure 11. Figures 11 and 12 also show the operations of delivery person A2 and resident A1 of apartment building 1.

[0099] Delivery person A2, for example, drives a delivery vehicle loaded with packages to apartment building 1 (M1).

[0100] Delivery person A2 uses the camera on their terminal 4 to read an identification image 3, such as a 2D code, attached to apartment building 1 (M2). The identification image 3 includes access information for accessing the information processing device 10, such as a URL (Uniform Resource Locator), and identification information such as the property management ID of apartment building 1 (see Figure 6).

[0101] Terminal 4 of delivery person A2 accesses the information processing device 10 based on the access information contained in the identification image 3 (S1). When terminal 4 accesses the information processing device 10, it transmits the identification information of the apartment building 1 contained in the identification image 3 to the information processing device 10 (S1).

[0102] The information processing device 10 requests location information from the terminal 4 that has accessed the information processing device 10 (S2).

[0103] In response to a request for location information from the information processing device 10, terminal 4 obtains its location, for example, based on a GPS signal (S3).

[0104] Terminal 4 transmits the acquired location information to the information processing device 10 (S4).

[0105] In S1, the information processing device 10 refers to the call data (see Figure 6) based on the identification information (property management ID) transmitted by terminal 4 and obtains location information (property location information) corresponding to the identification information (property management ID). Based on the location information obtained by referring to the call data (location information of apartment building 1) and the location information transmitted by terminal 4 in S4, the information processing device 10 determines whether terminal 4 is located within a certain range from apartment building 1 (S5).

[0106] If the information processing device 10 determines that terminal 4 is not located within a certain range from apartment building 1 (in the case of NO), it sends error information to terminal 4 (S6). The information that the information processing device 10 sends to terminal 4 may be information such as HTML (HyperText Markup Language) which displays a web page on a browser.

[0107] Terminal 4 receives error information transmitted by the information processing device 10 in S4. Based on the received information, Terminal 4 displays a screen on its display indicating that it is not possible to call resident A1 of apartment building 1 (S7). For example, Terminal 4 displays a screen in its browser indicating that it is not possible to call resident A1 of apartment building 1.

[0108] If the information processing device 10 determines that terminal 4 is located within a certain range from apartment building 1 (if YES), it sends screen information to terminal 4 to call resident A1 of apartment building 1 (S8). Also, if the information processing device 10 determines that terminal 4 is located within a certain range from apartment building 1 (if YES), it requests terminal 4 to turn on a camera, such as the front camera (S8).

[0109] In response to S8's camera-on request, terminal 4 turns on its own front camera, for example (S9).

[0110] Terminal 4 receives the call screen information transmitted by the information processing device 10 in S8. Based on the received information, Terminal 4 displays a screen in its browser to call resident A1 of apartment building 1 (see Figure 7) (S10).

[0111] Delivery person A2 enters the room number of resident A1 at the delivery destination on the screen displayed on terminal 4's display, and taps the call button (M3).

[0112] Terminal 4 transmits the room number and call request to the information processing device 10 in response to the operation of delivery person A2 of M3 (S11).

[0113] In S11, the information processing device 10 receives the room number transmitted by terminal 4. In S12, the information processing device 10 determines whether the received room number corresponds to the identification information (property management ID) transmitted by terminal 4 in S1 and is stored in the call data (see Figure 6). In other words, the information processing device 10 determines whether resident A1 of apartment building 1 has registered the room number in the call system.

[0114] If the information processing device 10 determines that resident A1 of apartment building 1 has not registered their room number in the calling system (if the answer is NO), it sends error information to terminal 4 (S13).

[0115] Terminal 4 receives error information transmitted by the information processing device 10 in S13. Based on the received information, Terminal 4 displays a screen on its display indicating that it is not possible to call resident A1 of apartment building 1 (S14). Terminal 4 displays a screen indicating that it is not possible to call resident A1 of apartment building 1, for example, in a browser.

[0116] If the information processing device 10 determines that resident A1 of apartment building 1 has registered their room number in the call system (if YES), it transmits the information on the call screen to terminal 4 (S15).

[0117] Terminal 4 receives the call screen information transmitted by the information processing device 10 in S15. Based on the received information, Terminal 4 displays a screen in its browser indicating that it is calling resident A1 of apartment building 1 (see Figure 8) (S16).

[0118] If the information processing device 10 determines that resident A1 of apartment building 1 has registered their room number in the calling system (if YES), it refers to the calling data (see Figure 6) and obtains the resident terminal ID corresponding to the room number transmitted by terminal 4 in S11. In other words, the information processing device 10 obtains the ID of the calling destination device corresponding to the room number. The information processing device 10 uses the obtained resident terminal ID to call the terminal (S17). Note that the information processing device 10 may perform the process in S17 before the process in S15.

[0119] In response to the call processing in S17, the information processing device 10 establishes (connects) a video and audio communication path between the terminal 4 of delivery person A2 and the terminal 2 of resident A1 of apartment building 1 (S18). At the time of establishing the communication path in S18, the information processing device 10 does not permit voice communication between terminal 2 and terminal 4, but transmits the image from the camera of terminal 4, which was turned on in S9, to terminal 2.

[0120] In response to the call processing in S17, the call system application is activated on terminal 2 of resident A1 of apartment building 1, and a call screen is displayed on the display (S19). The call screen displays the camera image of terminal 4, which was turned on in S9, that is, the camera image of terminal 4 of delivery person A2 who called terminal 2 (see Figures 9 and 10).

[0121] In other words, at S19, the display on delivery person A2's terminal 4 shows a call in progress screen (see Figure 8). Meanwhile, the terminal 2 of resident A1 of apartment building 1 shows an image of delivery person A2 who called resident A1 (see Figures 9 and 10).

[0122] Resident A1 of apartment building 1, who possesses terminal 2, performs a response operation (M4). For example, resident A1 of apartment building 1, who possesses terminal 2, performs a response operation if they recognize the caller as a delivery person based on the facial image displayed on the calling screen.

[0123] Furthermore, the actions taken if resident A1 of apartment building 1, who possesses terminal 2, does not respond (i.e., rejects the call), will be explained in the sequence shown in Figure 13.

[0124] Terminal 2 transmits response information to the information processing device 10 in response to M4's response operation (S20). In response to the transmission of the response information in S20, the information processing device 10 transmits response information to the delivery person A2's terminal 4 (S20a).

[0125] Based on the response information transmitted by terminal 2 in S20, the information processing device 10 switches the calling screen displayed on terminal 2 and terminal 4 to the call screen (S21a, S21b).

[0126] The information processing device 10 authorizes voice communication between terminal 2 and terminal 4 (S22). This enables communication between delivery person A2 and resident A1 of apartment building 1. The information processing device 10 may also transmit images captured by terminal 4's camera to terminal 2 after authorizing voice communication.

[0127] Resident A1 of apartment building 1, who possesses terminal 2, performs the end call operation (M5).

[0128] Terminal 2 sends a disconnection request to the information processing device 10 in response to the call termination operation (S23).

[0129] In response to the disconnection request sent by terminal 2 in S23, the information processing device 10 disconnects the communication path between terminal 2 and terminal 4 (S24).

[0130] In the above example, resident A1 of apartment building 1, who possesses terminal 2, performed the call termination operation (M5), but delivery person A2 may also perform the call termination operation. The information processing device 10 may disconnect the communication path between terminal 2 and terminal 4 in response to delivery person A2's call termination operation.

[0131] Terminals 2 and 4 switch their displays to the call termination screen in response to the disconnection of the communication channel of the information processing device 10 in S24 (S25a, S25b).

[0132] Figure 13 is a sequence diagram showing an example of the operation of the call system. Figure 13 shows the sequence when resident A1 of apartment building 1, who possesses terminal 2, does not perform a response operation at M4 in Figure 12. The operations S1-S19 and M1-M3 described in Figures 11 and 12 are the same in the sequence of Figure 13, and their explanation is omitted.

[0133] Resident A1 of apartment building 1 who possesses terminal 2 performs a rejection operation (M11). For example, resident A1 of apartment building 1 who possesses terminal 2 performs a rejection operation if, based on the facial image displayed on the calling screen (see Figures 9 and 10), they recognize the caller as an unknown person. Alternatively, resident A1 of apartment building 1 who possesses terminal 2 may, for example, not notice the call on terminal 2 and remain inactive for a certain period of time (M11).

[0134] Terminal 2 transmits rejection information to the information processing device 10 in response to a rejection operation by M11 or inactivity for a certain period of time (S31).

[0135] Terminal 2 switches the calling screen displayed on its display to the end call screen in response to a rejection operation by M11 or a period of inactivity (S32).

[0136] In response to the rejection information sent by terminal 2 in S32, the information processing device 10 sends screen information to the delivery person A2's terminal 4 indicating that it was not possible to connect to resident A1 of apartment building 1 (S33).

[0137] Terminal 4, carried by delivery person A2, receives image information transmitted by the information processing device 10 in S33. Based on the received image information, terminal 4 displays an image on its display indicating that it was unable to connect to resident A1's terminal 2 (S34).

[0138] <Summary of the first embodiment> As described above, the communication unit 10c of the information processing device 10 receives identification information for identifying the apartment building 1 and location information of the terminal 4 from the terminal 4 of the delivery person A2. The control unit 10a determines whether the terminal 4 is located within a predetermined range from the apartment building 1 based on the location information of the apartment building 1 associated with the received identification information and the location information of the terminal 4. If the terminal 4 is located within a predetermined range from the apartment building 1, the communication unit 10c transmits image data to the terminal 4 for the delivery person A2 to call the terminal 2 of the resident of the apartment building 1.

[0139] This allows delivery person A2 to use terminal 4 to transmit identification information of apartment building 1 and location information of terminal 4 to information processing device 10, making it easy to call resident A1 of apartment building 1.

[0140] <Variation> • Variation 1 The above example describes calling residents of apartment buildings, but it can also be applied to calling residents of detached houses. For example, an identification image that identifies the detached house may be affixed to a structure such as the exterior wall or gate of the detached house. In the case of detached houses, the property name and room number are not registered in the call data. In the case of detached houses, the name of the registrant may be registered in the call data.

[0141] Figure 14 shows an example of a screen displayed on the terminal 4 in the case of a detached house. Screen A14a shown in Figure 14 is displayed when the delivery person A2 takes an identification image of the detached house using terminal 4 and terminal 4 is located within a certain range of the detached house.

[0142] As shown in screen A14a, the display of terminal 4 held by delivery person A2 shows the name (for example, last name) of the resident of the detached house whose identification image was taken by delivery person A2. The display of terminal 4 held by delivery person A2 also shows a "Call" button for calling the resident of the detached house. Delivery person A2 taps the "Call" button to call the resident of the detached house (the resident of the delivery destination).

[0143] When the “Call” button is tapped, terminal 4 uses its camera to photograph the owner of terminal 4, i.e., delivery person A2. Terminal 4 transmits the captured image, such as the facial image of delivery person A2, to the information processing device 10. The information processing device 10 transmits the received image to the terminal that delivery person A2 called.

[0144] Figure 15 shows an example of a screen displayed on the terminal 4's display. For example, when the “Call” button shown on screen A14a in Figure 14 is tapped, screen A15a shown in Figure 15 is displayed on the terminal 4's display. As shown on screen A15a, the display of terminal 4, held by delivery person A2, shows the calling screen. The display of terminal 4 shows the last name of the resident that delivery person A2 called.

[0145] Figure 16 shows an example of a screen displayed on a device owned by a resident of a detached house. Figure 16 shows a device 21, such as a smartphone, owned by the resident of the detached house.

[0146] For example, when the “Call” button shown on screen A14a in Figure 14 is tapped, screen A16a shown in Figure 16 is displayed on the display of terminal 21 held by the resident of the detached house. The display of terminal 21 shows the camera image from the terminal 4 of the person who called the resident of the detached house, i.e., the terminal 4 of delivery person A2.

[0147] A resident of a detached house who possesses terminal 21 can view the camera image displayed on terminal 21's screen and tap either the "Answer" button or the "Reject" button. For example, if the camera image displayed on terminal 21's screen is of a delivery person, the resident will tap the "Answer" button.

[0148] In this way, the camera image of the person making the call is displayed on the terminal 21 of the resident of the detached house. This allows the owner of the detached house to see the camera image of the person making the call displayed on the terminal 21 and decide whether to answer or reject the call.

[0149] Figure 17 shows an example of a screen displayed on the screen of another terminal belonging to a resident of a detached house. Figure 17 shows a call device 22, such as an intercom master unit, installed inside the resident's house.

[0150] For example, when the “Call” button shown on screen A14a in Figure 14 is tapped, screen A17a shown in Figure 17 is displayed on the display of the call device 22. The display of the call device 22 shows the camera image of the person who called the resident of the detached house.

[0151] Residents who have a call device 22 installed in their home can view the camera image displayed on the call device 22's screen and tap either the "Answer" button or the "Reject" button. For example, if the camera image displayed on the call device 22's screen is of a delivery person, they will tap the "Answer" button.

[0152] In this way, the camera image of the person making the call is displayed on the display of the call device 22. This allows residents who have the call device 22 installed in their home to see the camera image of the person making the call displayed on the display of the call device 22 and decide whether to respond to or reject the call.

[0153] • Variation 2 The above states that the call system application is not installed on delivery person A2's terminal 4 (i.e., the call screen and call screen are displayed in a browser, etc.), but this is not limited to this. The application for the operation of the call system may be installed on delivery person A2's terminal 4. The application for the operation of the call system may display the call screen and call screen on the display of delivery person A2's terminal 4.

[0154] • Modification example 3 The above assumes that the image captured by the calling terminal's camera is displayed during the call (on the call screen), but this is not the only possibility. If the called party responds, the image captured by the calling terminal's camera may be displayed on the called party's terminal's display. In this case, the information processing device 10 may establish a communication channel when it receives response information from the called party's terminal (for example, when it receives the response information transmitted in S20 of Figure 12).

[0155] • Modification 4 The calling screen (Figures 8 and 15) on terminal 4 held by delivery person A2 may display an image captured by the camera of terminal 4. Delivery person A2 can check whether their face image has been sent to the calling terminal by looking at the image displayed on the calling screen.

[0156] • Variation 5 In the above, the caller is defined as a delivery person, but this is not limited to them. The caller may be a visitor such as a friend. Also, the delivery person may be replaced with a delivery company, delivery person, delivery company, or caller. A resident may be replaced with a resident, occupant, or called person. A dwelling unit may be replaced with a residence. A telephone line may be referred to as a telephone line or a line based on a circuit-switched system. A data line may be referred to as a line based on a packet-switched system.

[0157] <Second Embodiment> In the second embodiment, a map is displayed on the display of the delivery person A2's terminal 4. The location of the apartment building to be delivered is displayed on the map, for example, as a pin image. In the second embodiment, for example, if a pin on the map is tapped and the location of the delivery person A2's terminal 4 is within a certain range from the tapped apartment building, the terminal 4 of the resident A1 of the delivery destination can be called.

[0158] <Screen example> Delivery person A2 activates the call system application implemented on terminal 4. Terminal 4 (application) acquires location information of terminal 4, for example, based on GPS signals. Terminal 4 transmits the acquired location information to the information processing device 10.

[0159] The information processing device 10 transmits map information of the area around terminal 4 to terminal 4 based on the location information transmitted from terminal 4. The information processing device 10 also transmits to terminal 4 a list of compatible properties, including information on apartment buildings that have implemented the calling system service, in the area around terminal 4. The list of compatible properties may include, for example, the property management ID and property location information as explained in Figure 6.

[0160] The storage unit 10b of the information processing device 10 stores the call data shown in Figure 6.

[0161] Terminal 4 displays a map image on its display based on map information transmitted from the information processing device 10. At the same time, terminal 4 displays a pin image on the map indicating the location of the apartment building based on the property location information of the corresponding property list transmitted from the information processing device 10.

[0162] In other words, the display of terminal 4 shows a map of the area around terminal 4 (delivery person A2), and also displays a pin image on the map indicating the location of the apartment building where the calling system service has been installed.

[0163] Figure 18 shows an example of a screen displayed on the terminal 4 according to the second embodiment. Screen A18a in Figure 18 shows a map displayed on the terminal 4 of delivery person A2. The map displayed on the screen is a map of the area where terminal 4 (delivery person A2) is located. The location of the apartment building where the calling system service has been introduced is shown on the map as a pin image A18b.

[0164] Delivery person A2 taps the pin image A18b displayed on the screen to select the delivery destination. Terminal 4 sends information to the information processing device 10 about which pin delivery person A2 selected. For example, terminal 4 sends the property management ID associated with the pin image selected by delivery person A2 to the information processing device 10.

[0165] The information processing device 10 refers to the call data (see Figure 6) and obtains the property name of apartment building 1 corresponding to the property management ID transmitted by terminal 4. Once the information processing device 10 obtains the property name, it sends an image of the call screen for calling resident A1, the recipient of the delivery, to terminal 4.

[0166] Figure 19 shows an example of a screen displayed on the terminal 4 according to the second embodiment. For example, when the pin image A18b displayed on screen A18a shown in Figure 18 is tapped, screen A19a shown in Figure 19 is displayed on the terminal 4's display.

[0167] As shown in screen A19a, the display of terminal 4 held by delivery person A2 shows the name of apartment building 1 corresponding to the pin image A18b that delivery person A2 tapped. The display of terminal 4 held by delivery person A2 also shows a key image for entering the room number of a resident of apartment building 1. Delivery person A2 enters the room number of resident A1 of apartment building 1, i.e., the room number of the resident to be delivered, into terminal 4 and taps the "Call" button.

[0168] When the “Call” button is tapped, terminal 4 uses its camera to photograph the owner of terminal 4, i.e., delivery person A2. Terminal 4 transmits the captured image, such as the facial image of delivery person A2, to the information processing device 10. The information processing device 10 transmits the received image to the terminal that the delivery person called.

[0169] The images displayed on the terminal being called are the same as the screen examples described in Figures 9 and 10, so their explanation will be omitted.

[0170] <Sequence> Figure 20 is a sequence diagram showing an example of the operation of the call system according to the second embodiment. Figure 20 also shows the operations of delivery person A2 and resident A1 of apartment building 1.

[0171] Delivery person A2, for example, travels in a delivery vehicle to a location near the delivery destination (M21).

[0172] Delivery person A2 operates terminal 4 to launch the call system application (APP) (M22).

[0173] Terminal 4 starts the calling system application in response to the startup operation of M21 (S41).

[0174] Terminal 4 obtains its location information, for example, based on a GPS signal (S42).

[0175] Terminal 4 displays a map of the area around the location information acquired in S42 (the area around Terminal 4's current location) on its display (S43).

[0176] Terminal 4 may also transmit the location information acquired in S42 to the information processing device 10. The information processing device 10 may acquire map information about the area surrounding the location information received from terminal 4 and transmit it to terminal 4. Terminal 4 may display a map on its display based on the map information transmitted from the information processing device 10.

[0177] Terminal 4 requests the information processing device 10 to provide a list of corresponding properties near the location information acquired in S42 (S44).

[0178] In response to the request in S44, the information processing device 10 sends the list of corresponding properties to the terminal (S45).

[0179] Terminal 4 receives the list of compatible properties transmitted by the information processing device 10 in S45. Based on the property location information of the received list of compatible properties, Terminal 4 displays the locations of the apartment buildings where the calling system service has been introduced as pin images on the map displayed on the display (S46).

[0180] Delivery person A2 selects the delivery destination by, for example, tapping a pin image on the map displayed on the screen (M23).

[0181] Terminal 4 transmits the property management ID (delivery destination information) associated with the pin image tapped by the operation of M23 to the information processing device 10 (S47).

[0182] The information processing device 10 requests location information from the terminal 4 that transmitted the delivery destination information to the information processing device 10 (S48).

[0183] The subsequent processing is the same as the processing from S3 onwards described in the sequences in Figures 11 and 12, and therefore the explanation is omitted. However, the information processing device 10 refers to the call data based on the property management ID received in S47 and obtains the corresponding property name, etc.

[0184] <Summary of the second embodiment> As described above, the communication unit 10c of the information processing device 10 transmits image data of a map image displayed on terminal 4 and image data of a pin image displayed on the map image that indicates the location of the apartment building that delivery person A2 is visiting, in response to a request from terminal 4 of delivery person A2. The communication unit 10c receives from terminal 4 the location information of the apartment building associated with the pin image selected by delivery person A2 and the location information of terminal 4. Based on the received location information of the apartment building and the location information of terminal 4, the control unit 10a determines whether terminal 4 is located within a predetermined range from the apartment building. If terminal 4 is located within a predetermined range from the apartment building, the communication unit 10c transmits image data to terminal 4 for delivery person A2 to call terminal 2 of the apartment building resident.

[0185] This allows delivery person A2 to use terminal 4 to transmit the location information of the apartment building to be delivered and the location information of terminal 4 to the information processing device 10, making it easy to call resident A1 of apartment building 1.

[0186] In the above example, the delivery address is assumed to be an apartment building, but it could also be a detached house. Furthermore, while the caller is assumed to be the delivery person, this is not the only option. The caller could be a visitor, such as a friend.

[0187] While embodiments have been described above with reference to the drawings, this disclosure is not limited to such examples. It will be apparent to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims. Such modifications or alterations are understood to fall within the technical scope of this disclosure. Furthermore, the components in the embodiments may be combined in any way without departing from the spirit of this disclosure. Also, variations in each embodiment may be combined in any way.

[0188] In the above-described embodiment, the notation "...part" used for each component may be replaced with other notations such as "...circuitry", "...assembly", "...device", "...unit", or "...module".

[0189] This disclosure can be implemented in software, hardware, or software in conjunction with hardware. Each functional block used in the description of the above embodiments may be implemented in part or in whole as an integrated circuit (LSI), and each process described in the above embodiments may be controlled in part or in whole by a single LSI or a combination of LSIs. An LSI may consist of individual chips, or it may consist of a single chip that includes some or all of the functional blocks. An LSI may have data inputs and outputs. Depending on the degree of integration, LSIs may be referred to as ICs, system LSIs, super LSIs, or ultra LSIs.

[0190] The method of integration is not limited to LSIs; it may also be implemented using dedicated circuits, general-purpose processors, or dedicated processors. Furthermore, FPGAs (Field Programmable Gate Arrays) that can be programmed after LSI manufacturing, or reconfigurable processors that allow for the reconfiguration of the connections and settings of circuit cells within the LSI, may also be used. This disclosure may be implemented as digital or analog processing.

[0191] Furthermore, if advancements in semiconductor technology or other derived technologies lead to the emergence of integrated circuit technologies that replace LSIs, then naturally, it would be possible to use those technologies to integrate functional blocks. The application of biotechnology, for example, is a possibility. [Industrial applicability]

[0192] This disclosure is useful for a call system that summons residents of an apartment building. [Explanation of Symbols]
