The numerical values, shapes, materials, components, arrangement positions and connection configurations of components, steps, and the order of steps shown in the following embodiments are examples only and are not intended to limit the present invention. Furthermore, components in the following embodiments that are not described in an independent claim will be described as optional components.

[0011] Please note that each figure is a schematic diagram and not necessarily a strictly accurate representation. Furthermore, in each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations may be omitted or simplified.

[0012] (Embodiment) [composition] First, the configuration of the location information output system according to the embodiment will be described. Figure 1 is a block diagram showing the functional configuration of the location information output system according to the embodiment.

[0013] The location information output system 10 is a system applied to a multi-unit dwelling 100. The multi-unit dwelling 100 is an example of a facility and a collective facility, specifically an apartment building, dormitory, or company housing. The multi-unit dwelling 100 comprises multiple private units 101 and a common area 102.

[0014] The location information output system 10 is a system that can output information that directly or indirectly indicates that the resident (user) of the private unit 101 has returned to the private unit 101, and that the resident has left the private unit 101.

[0015] For example, the location information output system 10 can notify family members of the resident who live far away from the apartment building 100 about the resident's return home and going out. Also, the location information output system 10 can provide information indicating whether the resident was staying in the exclusive area 101 or absent during a disaster or the like to the local government or the like. The location information output system 10 can provide the situation of the presence or absence (such as long-term absence) of the resident in the exclusive area 101 to the operator who provides the security service in the apartment building 100.

[0016] As shown in FIG. 1, the location information output system 10 includes a server system 20, an intercom system 30, a plurality of wireless routers 40, and a mobile terminal 50. Hereinafter, the configurations of the systems or devices included in the location information output system 10 will be described.

[0017] The server system 20 is a system realized by one or more server devices located outside the apartment building 100, for example. Specifically, the server system 20 includes a communication unit 21, an information processing unit 22, and a storage unit 23.

[0018] The communication unit 21 is a communication module (communication circuit) for the server system 20 to communicate with the intercom system 30 (gateway device 34), the mobile terminal 50, etc. via a wide-area communication network 80 such as the Internet. The communication performed by the communication unit 21 is, for example, wired communication, but may also be wireless communication. The communication standard used for communication is not particularly limited either.

[0019] The information processing unit 22 performs information processing for detecting the return and departure of residents. The information processing unit 22 is realized by, for example, a microcomputer, but may also be realized by a processor. The information processing unit 22 includes, as functional components, a first acquisition unit 24, a second acquisition unit 25, a third acquisition unit 26, and an output unit 27. The functions of the first acquisition unit 24, the second acquisition unit 25, the third acquisition unit 26, and the output unit 27 are realized, for example, by a microcomputer or a processor constituting the information processing unit 22 executing a computer program stored in the storage unit 23.

[0020] The storage unit 23 is a storage device that stores information necessary for the above information processing, a computer program executed by the information processing unit 22, and the like. The storage unit 23 is realized by, for example, a HDD (Hard Disk Drive), but may also be realized by a semiconductor memory or the like.

[0021] The intercom system 30 is a system provided in the apartment house 100. The intercom system 30 includes an intercom master unit 31, a lobby intercom 32, a control device 33, a gateway device 34, and an auto-lock door 35. The lobby intercom 32, the control device 33, the gateway device 34, and the auto-lock door 35 are provided in the common part 102 of the apartment house 100, and the intercom master unit 31 is provided in each of the plurality of private parts 101 of the apartment house 100.

[0022] The intercom master unit 31 is an information terminal fixedly installed in the private part 101 of the apartment house 100. The intercom master unit 31 performs information processing for a resident in the private part 101 to talk to a visitor via the lobby intercom 32 or an intercom slave unit (not shown). The intercom slave unit is a so-called door phone and is provided outside the entrance of the private part 101.

[0023] The intercom master unit 31 communicates with the lobby intercom 32 via the control device 33. In addition to the communication unit (communication circuit; not shown) used for communication with the lobby intercom 32, the intercom master unit 31 also includes a wireless communication unit 31a as a communication component. The wireless communication unit 31a is a communication circuit that performs short-range wireless communication with the mobile terminal 50 in accordance with a communication standard such as BLE (Bluetooth® Low Energy).

[0024] The lobby intercom 32 is an information terminal installed on the outside (outdoor side) of the automatic locking door 35 at the entrance (i.e., common area 102) of the apartment building 100. The lobby intercom 32 controls, for example, the automatic locking door 35. The lobby intercom 32 has a user interface consisting of a keypad and call buttons, and visitors to the apartment building 100 can enter the room number of their destination via the keypad to communicate with a resident and request the unlocking of the automatic locking door 35.

[0025] The lobby intercom 32 communicates with the intercom master unit 31 via the control device 33. In addition to the communication unit (communication circuit; not shown) used for communication with the intercom master unit 31, the lobby intercom 32 also includes a wireless communication unit 32a as a communication component. The wireless communication unit 32a is a communication circuit that performs short-range wireless communication with the mobile terminal 50 according to a communication standard such as BLE. Short-range wireless communication, in other words, is radio wave communication through a local communication network.

[0026] The control device 33 is a device that controls devices installed within the apartment building 100, and controls communication between devices installed within the apartment building 100 (for example, communication between the lobby intercom 32 and the intercom master unit 31).

[0027] The gateway device 34 is a communication device that allows devices installed in the apartment building 100, such as a lobby intercom 32 or an intercom master unit 31, to communicate with the server system 20 via a wide-area communication network 80.

[0028] The auto-locking door 35 is a door installed in the entrance (i.e., common area 102) of the apartment building 100. The auto-locking door 35 automatically locks (closes) after a certain period of time has elapsed since it was unlocked (or opened). The door of the auto-locking door 35 may be a sliding door or a hinged door.

[0029] The wireless router 40 is a wireless communication device used to connect the mobile terminal 50 to the wide-area communication network 80 (without going through the mobile communication network). The wireless router 40 performs short-range wireless communication with the mobile terminal 50 in accordance with communication standards such as Wi-Fi (registered trademark). While the mobile terminal 50 is communicating with the wireless router 40 via short-range wireless communication, it can connect to the wide-area communication network 80 via the wireless router.

[0030] Next, the mobile terminal 50 will be described. The mobile terminal 50 is a portable information terminal used by residents. The mobile terminal 50 is, for example, a smartphone or a tablet. Specifically, the mobile terminal 50 comprises a communication unit 51, a wireless communication unit 52, an information processing unit 53, a storage unit 54, and a location measurement unit 55.

[0031] The communication unit 51 is a communication circuit for the mobile terminal 50 to connect to the wide-area communication network 80 via wireless communication through the mobile communication network.

[0032] The wireless communication unit 52 is a communication circuit that enables the mobile terminal 50 to perform short-range wireless communication with the wireless communication unit 31a of the intercom master unit 31, the wireless communication unit 32a of the lobby intercom 32, and the wireless router 40. Specifically, the wireless communication unit 52 performs short-range wireless communication according to a communication standard such as BLE or Wi-Fi (registered trademark).

[0033] The information processing unit 53 performs a process (transmission process) to send information to the server system 20 for detecting when a resident leaves or returns home. The information processing unit 53 is implemented by, for example, a microcomputer, but may also be implemented by a processor or dedicated circuit. The functions of the information processing unit 53 are realized by the execution of a computer program (software) stored in the storage unit 54 by the hardware, such as the microcomputer or processor that constitutes the information processing unit 53.

[0034] The storage unit 54 is a storage device that stores the information necessary for the above-mentioned transmission process. The information stored in the storage unit 54 includes a computer program executed by the information processing unit 53. The computer program is, for example, a so-called application program (hereinafter also simply referred to as an app) that is pre-installed in the storage unit 54 by the user. The storage unit 54 is implemented by, for example, a semiconductor memory.

[0035] The position measurement unit 55 measures the current location of the mobile terminal 50 based on radio waves transmitted by artificial satellites. The position measurement unit 55 is implemented by a GNSS (Global Navigation Satellite System) module such as a GPS (Global Positioning System) module.

[0036] [Example of operation 1: Detects when the person leaves the house] The location information output system 10 can detect when a resident leaves the house. Figure 2 is a diagram illustrating the overview of the method for detecting when a resident leaves the house.

[0037] As shown in Figure 2, when a resident goes out, it is assumed that they move from inside the private unit 101 to outside the private unit 101 (Figure 2(a)), pass around the lobby intercom 32 in the common area 102 (Figure 2(b)), and then exit the apartment building 100.

[0038] Therefore, in Operation Example 1, the movement from inside the private unit 101 to outside the private unit 101 is detected by the termination of the communication connection (hereinafter also simply referred to as connection) between the mobile terminal 50 held by the resident and the wireless router 40. The arrival of the resident in the vicinity of the lobby intercom 32 is detected by the commencement of a connection between the mobile terminal 50 and the lobby intercom 32.

[0039] In the following example of operation 1, the wireless router 40 and the wireless communication unit 32a of the lobby intercom 32 transmit beacon signals. The local communication network including the wireless router 40 is referred to as the first communication network, and the local communication network including the wireless communication unit 32a is referred to as the second communication network.

[0040] The first communication network is a local communication network in the first area 101a, which includes at least a portion (and sometimes all) of the private unit 101 where the resident resides. The mobile terminal 50 can connect to the first communication network (hereinafter also simply referred to as "connected") when it is located within the range of the beacon signal (radio waves) of the wireless router 40 (≒ first area 101a).

[0041] The second communication network is a local communication network in the second area 102a. The second area corresponds to the area around the lobby intercom 32 and includes at least a part of the common area 102 where residents reside. The second area 102a is different from the first area 101a, is outside the first area 101a, and is closer to the entrance (doorway) of the apartment building 100 than the first area 101a. The mobile terminal 50 can connect to the second communication network when it is located within the range of the beacon signal (radio waves) of the wireless communication unit 32a (≒ second area 102a).

[0042] The mobile terminal 50 has a predetermined application installed for communication between the mobile terminal 50 and the server system 20. When the predetermined application is running, the information processing unit 53 sends first information to the server system 20 each time the connection status to the first communication network (connected or not connected) changes, and sends second information to the server system 20 each time the connection status to the second communication network changes.

[0043] Based on the above premises, we will now explain Operation Example 1, which is an example of an operation that detects when a resident leaves the premises, with reference to Figure 3. Figure 3 is a sequence diagram of Operation Example 1.

[0044] Initially, the resident is located in the first area 101a (i.e., within the private unit 101), and the wireless communication unit 52 of the mobile terminal 50 is connected to the first communication network, which includes the wireless router 40. In this state, if the resident holding the mobile terminal 50 moves from the private unit 101 to outside the private unit 101, the wireless communication unit 52 loses the ability to communicate with the wireless router 40, and the wireless communication unit 52 is disconnected from the first communication network. When the information processing unit 53 detects that the connection to the first communication network has been disconnected (S11), it transmits first information to the server system 20 (S12). More specifically, the first information is transmitted to the server system 20 by the communication unit 51. The first information is information regarding whether or not the mobile terminal 50 is connected to the first communication network.

[0045] The communication unit 21 of the server system 20 receives the first information. The first acquisition unit 24 acquires the first information (S13).

[0046] Subsequently, the resident proceeds to the second area 102a of the apartment building 100 (i.e., the common area 102, such as the entrance). When the resident enters the second area 102a, the wireless communication unit 52 of the mobile terminal 50 receives a beacon signal emitted by the wireless communication unit 32a of the lobby intercom 32 and begins connecting to the second communication network. When the information processing unit 53 detects the start of the connection to the second communication network (S14), it transmits the second information to the server system 20 (S15). More specifically, the second information is transmitted to the server system 20 by the communication unit 51. The second information is information regarding the positional relationship between the second area 102a and the mobile terminal 50, and in operation example 1, it is information regarding whether or not the mobile terminal 50 is connected to the second communication network.

[0047] The communication unit 21 of the server system 20 receives the second information. The second acquisition unit 25 acquires the second information (S16).

[0048] Based on the first information acquired in step S13 and the second information acquired in step S16, the output unit 27 determines whether the second information was acquired within a predetermined period starting from the timing when the first information was acquired (S17). In other words, based on the acquired first and second information, the output unit 27 determines whether the mobile terminal 50 moved from outside the second area 102a to inside the second area 102a within a predetermined period after the mobile terminal 50's connection status to the first communication network changed from connected to disconnected. The predetermined period is, for example, a period of several minutes to several tens of minutes.

[0049] If the output unit 27 determines that the second information has been acquired within a predetermined period, it outputs location information indicating that the resident has left the premises (that they have left the first area 101a) (S18). In other words, if the output unit 27 determines that the mobile terminal 50 has moved from outside the second area 102a to inside the second area 102a within a predetermined period after the mobile terminal 50's connection status to the first communication network changes from connected to disconnected, it outputs location information indicating that the resident has left the premises.

[0050] For example, location information is transmitted by the communication unit 21 to a mobile device owned by a family member of the resident. This allows the location information output system 10 to notify the resident's family that the resident has left the premises. In this case, the notification destination can be set by the resident's operation on the mobile device 50 running the specified application. Alternatively, the location information may be transmitted by the communication unit 21 to a server device used by a business operator providing security services in the apartment building 100. The output location information is stored in the storage unit 23 and may be provided to the business operator who needs the information at the time the information is needed.

[0051] Furthermore, if the output unit 27 determines in step S17 that the second information was not acquired within a predetermined period, it will not output location information indicating that the resident has left the premises. In other words, if the output unit 27 determines that the mobile terminal 50 did not move from outside the second area 102a to inside the second area 102a within a predetermined period after the mobile terminal 50's connection status to the first communication network changed from connected to disconnected, it will not output location information indicating that the resident has left the premises.

[0052] As explained above, the location information output system 10 (output unit 27) can output location information indicating that a resident has left the premises (left the first area 101a) when it determines, based on the acquired first and second information, that the connection status of the mobile terminal 50 to the first communication network has changed from connected to disconnected, and that the mobile terminal 50 has moved from outside the second area 102a to inside the second area 102a. The location information output system 10 can improve the accuracy of detecting when a resident leaves the premises compared to a system that detects when a resident leaves the premises using only the first information.

[0053] [Example of operation 2: Detecting when the person leaves the house] In Operation Example 1, whether or not a resident entered the second area 102a was determined by whether or not the mobile terminal 50 was connected to the second communication network. However, whether or not a resident entered the second area 102a may also be determined by the current location of the mobile terminal 50, as measured by the location measurement unit 55 of the mobile terminal 50. Such Operation Example 2 will be explained below with reference to Figure 4. Figure 4 is a sequence diagram of Operation Example 2.

[0054] The processing in steps S11 to S13 is the same as in Operation Example 1. In Operation Example 2, the location measurement unit 55 of the mobile terminal 50 running a predetermined application continuously measures the current location of the mobile terminal 50, and when a resident enters the second area 102a, the information processing unit 53 detects that the current location measured by the location measurement unit 55 has entered the second area 102a (S14a). The current location is represented, for example, by latitude and longitude, and the second area 102a is represented by a range of latitude and longitude.

[0055] In Operation Example 2, the second area 102a is set by a resident, for example, by a setting operation on a mobile terminal 50 running the predetermined application. The second area 102a may be set to include at least a part of the common area 102, such as the entrance, as in Operation Example 1, or it may be set to an area outside the apartment building 100 (an area that does not include the common area 102). The second area 102a should be set to an area where it is possible to know that a resident has left the apartment building 100.

[0056] When the information processing unit 53 detects that the current location of the mobile terminal 50 has entered the second area 102a, it transmits second information to the server system 20 (S15a). More specifically, the second information is transmitted to the server system 20 by the communication unit 51. The second information is information regarding the positional relationship between the second area 102a and the mobile terminal 50, and in operation example 2, it is information regarding the position of the mobile terminal 50 measured by the mobile terminal 50 based on radio waves transmitted by an artificial satellite. More specifically, the second information is information indicating whether or not the position of the mobile terminal 50 has entered the second area 102a. The second information is transmitted to the server system 20, for example, each time the position of the mobile terminal 50 changes, whether or not it is located within the second area 102a.

[0057] The communication unit 21 of the server system 20 receives the second information. The second acquisition unit 25 acquires the second information (S16a).

[0058] The output unit 27 determines, based on the first information acquired in step S13 and the second information acquired in step S16a, whether or not the second information was acquired within a predetermined period starting from the timing when the first information was acquired (S17). The processing from step S17 onward is the same as in Operation Example 1.

[0059] As described above, the location information output system 10 (output unit 27) can output location information indicating that a resident has left the premises (exited from the first area 101a) as measured by the location measurement unit 55. The location information output system 10 can improve the accuracy of detecting when a resident leaves the premises compared to a system that uses only the first information to detect when a resident leaves the premises.

[0060] In example 2, the detection of the mobile terminal 50 entering the second area 102a was performed by the mobile terminal 50, but this detection may also be performed by the output unit 27 of the server system 20.

[0061] For example, the mobile terminal 50 transmits the position (latitude and longitude) measured by the position measurement unit 55 to the server system 20 as second information. The second acquisition unit 25 acquires this second information, and the output unit 27 can detect whether the mobile terminal 50 has entered the second area 102a based on the acquired second information and the range of latitude and longitude corresponding to the second area 102a, which is set in advance by the resident. In this case as well, the second information can be said to be information regarding the position of the mobile terminal 50, measured by the mobile terminal 50 based on radio waves transmitted by an artificial satellite (more specifically, information that directly indicates the latitude and longitude of the mobile terminal 50).

[0062] [Example of operation 3: Detecting departure] In Operation Example 1, a third region different from both the first region 101a and the second region 102a may also be set. The third region may be set, for example, in the area surrounding the apartment building 100 but outside the apartment building 100. In this case, the location information output system 10 can detect that a resident has left the building, provided that the resident has finally entered the third region. Such Operation Example 3 will be described below with reference to Figure 5. Figure 5 is a sequence diagram of Operation Example 3.

[0063] The processing in steps S11 to S16 is the same as in Operation Example 1. In Operation Example 3, the location measurement unit 55 of the mobile terminal 50 running a predetermined application continuously measures the current location of the mobile terminal 50, and when a resident enters the third area, the information processing unit 53 detects that the current location measured by the location measurement unit 55 has entered the third area (S17b). The current location is represented, for example, by latitude and longitude, and the third area is represented by a range of latitude and longitude.

[0064] In Operation Example 3, the third area is set by a resident, for example, through a setting operation on the mobile terminal 50 running the predetermined application. The third area is set to an area that indicates the resident is outside the apartment building 100.

[0065] When the information processing unit 53 detects that the current location of the mobile terminal 50 has entered the third area, it transmits third information to the server system 20 (S18b). More specifically, the third information is transmitted to the server system 20 by the communication unit 51. The third information is information regarding the positional relationship between the third area and the mobile terminal 50, and in operation example 3, it is information regarding the position of the mobile terminal 50 measured by the mobile terminal 50 based on radio waves transmitted by an artificial satellite. More specifically, the third information is information indicating whether or not the position of the mobile terminal 50 has entered the third area. The third information is transmitted to the server system 20, for example, each time the position of the mobile terminal 50 changes.

[0066] The communication unit 21 of the server system 20 receives the third information. The third acquisition unit 26 acquires the third information (S19b).

[0067] Based on the first information acquired in step S13, the second information acquired in step S16, and the third information acquired in step S19b, the output unit 27 determines whether the second and third information were acquired in this order within a predetermined period starting from the timing when the first information was acquired (S20b). In other words, based on the acquired first information, second information, and third information, the output unit 27 determines whether the mobile terminal 50 moved from outside the second area 102a into the second area 102a and then entered the third area within a predetermined period after the mobile terminal 50's connection status to the first communication network changed from connected to disconnected. The predetermined period is, for example, a period of several minutes to several tens of minutes.

[0068] If the output unit 27 determines that the second and third pieces of information have been acquired in that order within a predetermined period, it outputs location information indicating that the resident has left the premises (has left the first area 101a) (S21b). In other words, if the output unit 27 determines that the mobile terminal 50 has moved from outside the second area 102a to inside the second area 102a and then entered the third area within a predetermined period after the mobile terminal 50's connection status to the first communication network has changed from connected to disconnected, it outputs location information indicating that the resident has left the premises. The processing in step S21b is the same as the processing in step S18 of Operation Example 1.

[0069] Furthermore, if the output unit 27 determines in step S20b that the second and third pieces of information were not acquired in that order within a predetermined period, it will not output location information indicating that the resident has left the premises. In other words, if the output unit 27 determines that the mobile terminal 50 moved from outside the second area 102a to inside the second area 102a within a predetermined period after the mobile terminal 50's connection status to the first communication network changed from connected to disconnected, and then did not enter the third area, it will not output location information indicating that the resident has left the premises.

[0070] As described above, the location information output system 10 (output unit 27) can output location information indicating that a resident has left the premises (exited from the first area 101a) when it determines, based on the acquired first information, second information, and third information, that the connection status of the mobile terminal 50 to the first communication network has changed from connected to disconnected, and that the mobile terminal 50 has moved from outside the second area 102a to inside the second area 102a and then entered the third area. The location information output system 10 can further improve the accuracy of detecting when a resident leaves the premises.

[0071] In operation example 3, the detection of the mobile terminal 50 entering the third area was performed by the mobile terminal 50, but this detection may also be performed by the output unit 27 of the server system 20.

[0072] For example, the mobile terminal 50 transmits the position (latitude and longitude) measured by the position measurement unit 55 to the server system 20 as third information. The third acquisition unit 26 acquires this third information, and the output unit 27 can detect whether the mobile terminal 50 has entered the third area based on the acquired third information and the range of latitude and longitude corresponding to the third area, which is set in advance by the resident. In this case as well, the third information can be said to be information about the position of the mobile terminal 50 measured by the mobile terminal 50 based on radio waves transmitted by an artificial satellite (more specifically, information that directly indicates the latitude and longitude of the mobile terminal 50).

[0073] [Example of operation 4: Detecting return home] The location information output system 10 can detect when a resident has returned home. Figure 6 is a diagram illustrating the overview of the method for detecting when a resident has returned home.

[0074] As shown in Figure 6, when a resident returns home, it is assumed that they will pass by the lobby intercom 32 in the common area 102 (Figure 6(a)) and then move into the private area 101 (Figure 6(b)).

[0075] Therefore, in Operation Example 4, the arrival of the resident near the lobby intercom 32 is detected by the commencement of a connection between the mobile terminal 50 and the lobby intercom 32. Subsequently, the resident's movement into the private unit 101 is detected by the commencement of a communication connection between the mobile terminal 50 carried by the resident and the wireless router 40. Operation Example 4 will be explained below with reference to Figure 7. Figure 7 is a sequence diagram of Operation Example 4.

[0076] Initially, the resident is located outside the apartment building 100. The resident then heads towards the second area 102a of the apartment building 100 (i.e., the common area 102, such as the entrance).

[0077] When a resident enters the second area 102a, the wireless communication unit 52 of the mobile terminal 50 receives a beacon signal emitted by the wireless communication unit 32a of the lobby intercom 32 and starts connecting to the second communication network. When the information processing unit 53 detects the start of the connection to the second communication network (S21), it transmits second information to the server system 20 (S22). More specifically, the second information is transmitted to the server system 20 by the communication unit 51. The second information is information regarding the positional relationship between the second area 102a and the mobile terminal 50, and in operation example 4, it is information regarding whether or not the mobile terminal 50 is connected to the second communication network.

[0078] The communication unit 21 of the server system 20 receives the second information. The second acquisition unit 25 acquires the second information (S23).

[0079] Subsequently, the resident proceeds to the first area of ​​the apartment building 100 (i.e., the private unit 101). When the resident enters the first area, the wireless communication unit 52 of the mobile terminal 50 receives a beacon signal emitted by the wireless router 40 and begins connecting to the first communication network. When the information processing unit 53 detects the start of the connection to the first communication network (S24), it transmits the first information to the server system 20 (S25). More specifically, the first information is transmitted to the server system 20 by the communication unit 51. The first information is information regarding whether or not the mobile terminal 50 is connected to the first communication network.

[0080] The communication unit 21 of the server system 20 receives the first information. The first acquisition unit 24 acquires the first information (S26).

[0081] Based on the second information acquired in step S23 and the first information acquired in step S26, the output unit 27 determines whether or not the first information was acquired within a predetermined period starting from the timing when the second information was acquired (S27). In other words, based on the acquired first and second information, the output unit 27 determines whether or not the connection status of the mobile terminal 50 to the first communication network changed from no connection to connected within a predetermined period after the mobile terminal 50 moved from outside the second area 102a to inside the second area 102a. The predetermined period is, for example, a period of several minutes to several tens of minutes.

[0082] If the output unit 27 determines that the first information has been acquired within a predetermined period, it outputs location information indicating that the resident has returned home (entered the first area 101a) (S28). In other words, if the output unit 27 determines that the connection status of the mobile terminal 50 to the first communication network has changed from no connection to a connection within a predetermined period after the mobile terminal 50 has moved from outside the second area 102a to inside the second area 102a, it outputs location information indicating that the resident has returned home.

[0083] For example, location information is transmitted by the communication unit 21 to a mobile device owned by a family member of the resident. This allows the location information output system 10 to notify the resident's family of the resident's return home. In this case, the notification destination can be set by the resident's operation on the mobile device 50 running the specified application. Alternatively, location information may be transmitted by the communication unit 21 to a server device used by a business operator providing security services in the apartment building 100.

[0084] Furthermore, if the output unit 27 determines in step S27 that the first information was not acquired within a predetermined period, it will not output location information indicating that the resident has returned home. In other words, if the output unit 27 determines that the connection status of the mobile terminal 50 to the first communication network did not change from no connection to connected within a predetermined period after the mobile terminal 50 moved from outside the second area 102a to inside the second area 102a, it will not output location information indicating that the resident has returned home.

[0085] As described above, the location information output system 10 (output unit 27) can output location information indicating the resident's return home (entry into the first area 101a) when it determines, based on the acquired first and second information, that the mobile terminal 50 has moved from outside the second area 102a to inside the second area 102a, and that the connection status of the mobile terminal 50 to the first communication network has changed from no connection to a connection. The location information output system 10 can improve the accuracy of detecting the resident's return home compared to a system that detects the resident's return home using only the first information.

[0086] In example 4, the predetermined period was defined as the period starting from the moment the resident entered the second area 102a from outside. However, the period may also be defined as the moment the resident enters the second area 102a from outside and then leaves the second area 102a.

[0087] As described above, the mobile terminal 50 transmits second information each time the connection status to the second communication network changes. Therefore, after step S23 and before step S24, it may transmit second information to the server system 20 in response to detecting that the connection to the second communication network has been terminated.

[0088] Therefore, the output unit 27 of the server system 20 makes the following determination, using the timing when this second information (the second second information) is acquired by the second acquisition unit 25 as the starting point of a predetermined period.

[0089] Based on the acquired first and second information, the output unit 27 determines that the connection status of the mobile terminal 50 to the first communication network has changed from no connection to a connection within a predetermined period of time after the mobile terminal 50 has moved in the following order: outside the second area 102a (outdoor side of the second area 102a), inside the second area 102a, and outside the second area 102a (indoor side of the second area 102a). In such cases, the output unit 27 outputs location information indicating the resident's entry into the first area 101a.

[0090] Based on the acquired first and second information, the output unit 27 determines that the mobile terminal 50 has moved in the order of outside the second area 102a, inside the second area 102a, and outside the second area 102a, and within a predetermined period of time, the connection status of the mobile terminal 50 to the first communication network has not changed from no connection to connected, and therefore does not output location information.

[0091] In this way, based on the acquired first and second information, the output unit 27 can output location information indicating the resident's entry into the first area 101a when it determines that the mobile terminal 50 has moved in the order of outside the second area 102a, inside the second area 102a, and outside the second area 102a, and that the connection status of the mobile terminal 50 to the first communication network has changed from no connection to a connection.

[0092] [Example of operation 5] In Operation Example 4, whether or not a resident entered the second area 102a was determined by whether or not the mobile terminal 50 was connected to the second communication network. However, whether or not a resident entered the second area 102a may also be determined by the current location of the mobile terminal 50, as measured by the location measurement unit 55 of the mobile terminal 50. Such Operation Example 5 will be described below with reference to Figure 8. Figure 8 is a sequence diagram of Operation Example 5.

[0093] In Operation Example 5, the location measurement unit 55 of the mobile terminal 50 running a predetermined application continuously measures the current location of the mobile terminal 50. When a resident enters the second area 102a, the information processing unit 53 detects that the current location measured by the location measurement unit 55 has entered the second area 102a (S21a). The current location is represented, for example, by latitude and longitude, and the second area 102a is represented by a range of latitude and longitude.

[0094] In Operation Example 5, the second area 102a is set by a resident, for example, by a setting operation on a mobile terminal 50 running the predetermined application. The second area 102a may be set to include at least a part of the common area 102, such as the entrance, as in Operation Example 4, or it may be set to an area immediately outside the apartment building 100 (an area that does not include the common area 102). The second area 102a should be set to an area that allows it to be determined when a resident has returned to the apartment building 100 from being out.

[0095] When the information processing unit 53 detects that the current location of the mobile terminal 50 has entered the second area 102a, it transmits second information to the server system 20 (S22a). More specifically, the second information is transmitted to the server system 20 by the communication unit 51. The second information is information regarding the positional relationship between the second area 102a and the mobile terminal 50, and in operation example 5, it is information regarding the position of the mobile terminal 50 measured by the mobile terminal 50 based on radio waves transmitted by an artificial satellite. More specifically, the second information is information indicating whether or not the position of the mobile terminal 50 has entered the second area 102a. The second information is transmitted to the server system 20, for example, each time the position of the mobile terminal 50 changes.

[0096] The communication unit 21 of the server system 20 receives the second information. The second acquisition unit 25 acquires the second information (S23a). The processing in steps S24 to S27 thereafter is the same as in operation example 4.

[0097] As described above, the location information output system 10 (output unit 27) can output location information indicating the resident's return home (entry into the first area 101a) as measured by the location measurement unit 55. The location information output system 10 can improve the accuracy of detecting when a resident leaves the premises compared to a system that detects when a resident leaves using only the first information.

[0098] In example 5, the detection of the mobile terminal 50 entering the second area 102a was performed by the mobile terminal 50, but this detection may also be performed by the output unit 27 of the server system 20.

[0099] For example, the mobile terminal 50 transmits the position (latitude and longitude) measured by the position measurement unit 55 to the server system 20 as second information. The second acquisition unit 25 acquires this second information, and the output unit 27 can detect whether the mobile terminal 50 has entered the second area 102a based on the acquired second information and the range of latitude and longitude corresponding to the second area 102a, which is set in advance by the resident. In this case as well, the second information can be said to be information regarding the position of the mobile terminal 50, measured by the mobile terminal 50 based on radio waves transmitted by an artificial satellite (more specifically, information that directly indicates the latitude and longitude of the mobile terminal 50).

[0100] Furthermore, in example 5, the predetermined period was defined as the period starting from the moment the resident entered the second area 102a from outside. However, the period may also be defined as the moment the resident entered the second area 102a from outside and then left the second area 102a.

[0101] As described above, the mobile terminal 50 transmits the second information each time its location within the second area 102a changes. Therefore, after step S23a and before step S24, the mobile terminal 50 may transmit the second information to the server system 20 in response to having moved outside the second area 102a.

[0102] Therefore, the output unit 27 of the server system 20 makes the following determination, using the timing when this second information (the second second information) is acquired by the second acquisition unit 25 as the starting point of a predetermined period.

[0103] Based on the acquired first and second information, the output unit 27 determines that the connection status of the mobile terminal 50 to the first communication network changed from no connection to a connection within a predetermined period after the mobile terminal 50 moved in the order of outside the second area 102a (outdoor side of the second area 102a), inside the second area 102a, and outside the second area 102a (indoor side of the second area 102a), and outputs location information indicating the resident's entry into the first area 101a. Based on the acquired first and second information, the output unit 27 determines that the connection status of the mobile terminal 50 to the first communication network did not change from no connection to a connection within a predetermined period after the mobile terminal 50 moved in the order of outside the second area 102a, inside the second area 102a, and outside the second area 102a, and does not output location information.

[0104] In this way, based on the acquired first and second information, the output unit 27 can output location information indicating the resident's entry into the first area 101a when it determines that the mobile terminal 50 has moved in the order of outside the second area 102a, inside the second area 102a, and outside the second area 102a, and that the connection status of the mobile terminal 50 to the first communication network has changed from no connection to a connection.

[0105] [Differentiation] In the above operation examples 1 to 5, the location information output system 10 detected that the resident had moved from inside the private unit 101 to outside the private unit 101, and that the resident had moved from outside the private unit 101 to inside the private unit 101, based on whether or not there was a connection between the mobile terminal 50 and the wireless router 40. However, the location information output system 10 may also detect that the resident had moved from inside the private unit 101 to outside the private unit 101, and that the resident had moved from outside the private unit 101 to inside the private unit 101, based on whether or not there was a connection between the mobile terminal 50 and the intercom master unit 31. In other words, in operation examples 1 to 5, the wireless router 40 may be replaced with the intercom master unit 31 (wireless communication unit 31a).

[0106] Furthermore, in the above operation examples 1 to 5, if the intercom master unit 31 is used instead of the wireless router 40, the intercom master unit 31 may emit a beacon signal and the mobile terminal 50 may receive the beacon signal, or conversely, the mobile terminal 50 may emit a beacon signal and the intercom master unit 31 may receive the beacon signal.

[0107] Furthermore, in the above operation examples 1, 3-4, the lobby intercom 32 (wireless communication unit 32a) emitted a beacon signal and the mobile terminal 50 received the beacon signal. However, conversely, the mobile terminal 50 may emit a beacon signal and the lobby intercom 32 may receive the beacon signal.

[0108] Furthermore, in the above operation examples 1 to 5, the first information indicating the connection status between the mobile terminal 50 and the wireless router 40 was transmitted from the mobile terminal 50 to the server system 20, but it may also be transmitted from the wireless router 40 to the server system 20. If an intercom master unit 31 is used instead of the wireless router 40, the first information indicating the connection status between the mobile terminal 50 and the intercom master unit 31 may be transmitted from the mobile terminal 50 to the intercom master unit 31, or from the intercom master unit 31 to the server system 20. More specifically, transmission from the intercom master unit 31 to the server system 20 means transmission from the intercom master unit 31 to the server system 20 via the control device 33, gateway device 34, and wide-area communication network 80.

[0109] Furthermore, in the above operation examples 1, 3-4, the second information indicating the connection status between the mobile terminal 50 and the lobby intercom 32 was transmitted from the mobile terminal 50 to the server system 20, but it may also be transmitted from the lobby intercom 32 to the server system 20. More specifically, transmission from the lobby intercom 32 to the server system 20 means transmission from the lobby intercom 32 to the server system 20 via the control device 33, gateway device 34, and wide-area communication network 80.

[0110] Furthermore, in the above operation examples 1 to 5, some or all of the processing for outputting location information performed by the server system 20 may be performed by the mobile terminal 50. In other words, some or all of the first acquisition unit 24, the second acquisition unit 25, the third acquisition unit 26, and the output unit 27 may be provided by the mobile terminal 50.

[0111] Furthermore, some or all of the processing for outputting location information may be performed by devices or systems installed within the apartment building 100. In other words, some or all of the first acquisition unit 24, the second acquisition unit 25, the third acquisition unit 26, and the output unit 27 may be provided by devices or systems installed within the apartment building 100.

[0112] For example, some or all of the processing for outputting location information may be performed by the intercom system 30 (more specifically, the control device 33, etc.) or by an edge server (not shown) installed in the apartment building 100. If an EMS such as HEMS (Home Energy Management System) is installed in the apartment building 100, some or all of the processing for outputting location information may be performed by the EMS controller.
