DETAILED DESCRIPTION OF THE INVENTION

[0017] In recent years, due to increased awareness of crime prevention, many parents have their children carry mobile devices such as GPS (Global Positioning System) devices when they go out, such as to school or cram school. This allows parents to monitor their children from a distance by checking the mobile device's location data using an application installed on a smartphone or other device. Furthermore, there has been a growing need for mobile devices, primarily those carried by children, to be equipped with a calling function so that parents can call their children while they are out. However, the power consumption of mobile devices equipped with a calling function tends to be higher than that of mobile devices without a calling function, such as GPS devices specialized for positioning. For these reasons, it is desirable to appropriately reduce the power consumption of mobile devices equipped with both positioning and calling functions.

[0018] In the system according to the present embodiment, a monitoring system in which a watcher, such as a parent, watches over a target, such as a child, employs a mechanism for setting the operation mode of a mobile device carried by the target. For example, the mobile device is equipped with a positioning function that can measure its own location and a communication function that can communicate with a communication terminal carried by the watcher. When the mobile device measures its own location using the positioning function, it transmits its own location data so that the watcher can grasp the location of the target. The mobile device has two operation modes: a first operation mode and a second operation mode that consumes less power than the first operation mode. The mobile device sets its operation mode to either the first operation mode or the second operation mode based on schedule data for setting its operation mode and terminal status data that indicates the terminal status of the mobile device. This allows the operation mode of the mobile device to be flexibly set according to the schedule of the operation mode of the mobile device indicated by the schedule data and the terminal status of the mobile device, thereby enabling the mobile device to appropriately reduce power consumption.

[0019] In particular, the system according to the present embodiment employs a mechanism for setting the operation mode of the mobile device based on, for example, the schedule data and terminal state data including stationary state data indicating whether the mobile device is stationary and charging state data indicating whether the mobile device is charging. For example, if the operation mode of the mobile device in the schedule data corresponding to the timing at which the operation mode is set is scheduled to be the second operation mode and the terminal state of the mobile device is both stationary and non-charging, the mobile device sets the operation mode of the mobile device to the second operation mode. When the operation mode of the mobile device is set to the second operation mode, the mobile device controls the call function and the positioning function so that they are inactive. On the other hand, when the operation mode of the mobile device in the schedule data corresponding to the timing is scheduled to be the first operation mode or when the terminal state of the mobile device is at least one of a non-stationary state and a charging state, the mobile device sets the operation mode of the mobile device to the first operation mode. When the operation mode of the mobile device is set to the first operation mode, the mobile device controls the call function and the positioning function so that they are active. As a result, when the mobile terminal is unlikely to be used and no external power is being supplied to the mobile terminal, the power consumption of the mobile terminal can be reduced by deactivating the call function and positioning function. On the other hand, when the mobile terminal is likely to be used or when external power is being supplied to the mobile terminal, the call function and positioning function can be activated to prevent degradation of the user experience of the mobile terminal. As a result, the mobile terminal can achieve both reduced power consumption and prevention of degradation of the user experience.

[0020] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention as claimed. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. In the drawings, the same reference numerals are used to designate the same or similar parts, and redundant explanations may be omitted.

[0026] A watcher watches over, for example, one watch target. A watcher watches over, for example, multiple watch targets. For example, if the watcher is a mother of two children, the mother watches over the two children as watch targets.

[0027] The mobile terminal 100 may be any mobile terminal as long as it is capable of accessing the network 20. The mobile terminal 100 may be carried by the watching target 105.

[0028] The network 20 may include a core network provided by one or more telecommunications carriers. The core network may be compliant with, for example, the Long Term Evolution (LTE) communication system. The core network may be compliant with, for example, the 5G (5th Generation) communication system. The core network may be compliant with a mobile communication system such as the 6G (6th Generation) communication system or later. The core network may be compliant with the 3G (3rd Generation) communication system. The network 20 may include the Internet.

Here, GPS positioning and Real Time Kinematic (RTK) positioning are shown as examples of GNSS positioning. The positioning function may also include a function to perform base station positioning.

[0032] For example, the mobile terminal 100 measures the position of the mobile terminal 100. Here, the position of the mobile terminal 100 may be considered to be the position of the watching target 105 who carries the mobile terminal 100.

[0033] The position of the mobile terminal 100 indicates, for example, a two-dimensional position of the mobile terminal 100. The two-dimensional position may be expressed by latitude and longitude. The position of the mobile terminal 100 indicates, for example, a three-dimensional position of the mobile terminal 100. The three-dimensional position may be expressed by latitude, longitude, and altitude.

[0034] The mobile terminal 100 is equipped with, for example, a sensor that functions as a positioning function. Here, a GNSS sensor, a GPS sensor, and an RTK sensor are shown as examples of sensors that function as a positioning function.

[0035] The mobile terminal 100 is equipped with, for example, a call function. The call function may be a function for performing communication through transmission and reception of audio signals.

[0036] The call function includes, for example, a function for making a call using a packet line system. Here, VoIP (Voice over IP) and VoLTE (Voice over LTE) are shown as examples of a call using a packet line system. The call function may also include a function for making a call using a telephone line system.

[0037] The mobile terminal 100 is equipped with, for example, a control function. The control function may be a function for controlling various functions equipped in the mobile terminal 100.

[0038] The mobile terminal 100 controls, for example, a call function of the mobile terminal 100. The mobile terminal 100 controls, for example, the call function of the mobile terminal 100 so that a call between the mobile terminal 100 and the communication terminal 200 is established.

[0039] The mobile terminal 100 is equipped with, for example, a measurement function. The measurement function may be a function for measuring the terminal state of the mobile terminal 100.

[0040] The terminal state of the mobile terminal 100 includes, for example, a stationary state. The stationary state is a state in which the mobile terminal 100 is stationary. The terminal state of the mobile terminal 100 includes, for example, a non-stationary state. The non-stationary state is a state in which the mobile terminal 100 is not stationary. Note that a moving state in which the mobile terminal 100 is moving may be an example of the non-stationary state. The terminal state of the mobile terminal 100 includes, for example, a charging state. The charging state is a state in which power is being supplied to a battery installed in the mobile terminal 100. The terminal state of the mobile terminal 100 includes, for example, a non-charging state. The non-charging state is a state in which power is not being supplied to a battery installed in the mobile terminal 100.

[0041] The mobile terminal 100 is equipped with, for example, a sensor that functions as a measurement function. Here, a speed sensor, an acceleration sensor, an angle sensor, a gyro sensor, an IMU (Inertial Measurement Unit), a voltage sensor, and a current sensor are shown as examples of sensors that function as a measurement function.

[0042] The mobile terminal 100 is equipped with, for example, a communication function. The communication function may be a function for executing communication with a communication target. Note that a call function may be an example of the communication function.

[0043] The mobile terminal 100 communicates with a communication target of the mobile terminal 100, for example, via the network 20. The mobile terminal 100 communicates with a communication target of the mobile terminal 100, for example, via the wireless base station 30 and the network 20. Here, the communication terminal 200 and the management device 300 are shown as examples of a communication target of the mobile terminal 100.

[0044] For example, the mobile terminal 100 receives various types of data. For example, the mobile terminal 100 receives schedule data for the operation mode of the mobile terminal 100. The schedule data for the operation mode of the mobile terminal 100 is, for example, schedule data for setting the operation mode of the mobile terminal 100 to a first operation mode or a second operation mode that consumes less power than the first operation mode. Note that the first operation mode may be referred to as a normal mode, and the second operation mode may be referred to as a power saving mode.

[0045] For example, the mobile terminal 100 sets the operation mode of the mobile terminal 100 based on the schedule data of the operation mode of the mobile terminal 100. Details of setting the operation mode of the mobile terminal 100 based on the schedule data of the operation mode of the mobile terminal 100 will be described later.

[0046] For example, in the normal mode, the positioning function of the mobile terminal 100 is active. For example, in the normal mode, the positioning function and the call function of the mobile terminal 100 are active.

[0047] For example, in the power saving mode, the call function of the mobile terminal 100 is inactive. For example, in the power saving mode, the positioning function and the call function of the mobile terminal 100 are inactive.

[0048] The mobile terminal 100 transmits, for example, various types of data. For example, the mobile terminal 100 transmits position data indicating the position of the mobile terminal 100 measured by a positioning function installed in the mobile terminal 100.

[0049] The user of the mobile terminal 100 includes, for example, the watched target 105. The user of the mobile terminal 100 includes, for example, the watcher 205 who allows the watched target 105 to carry the mobile terminal 100. Therefore, the user experience of the mobile terminal 100 may include not only the user experience of the watched target 105 who carries the mobile terminal 100, but also the user experience of the watcher 205.

[0050] The communication terminal 200 may be any communication terminal that is capable of accessing the network 20. The communication terminal 200 may be carried by the watcher 205.

[0051] The communication terminal 200 is, for example, a mobile phone such as a smartphone, a tablet terminal, a wearable terminal, etc. The communication terminal 200 may also be a PC (Personal Computer).

[0052] For example, the watcher 205 watches over the watching target 105 by executing an application using the communication terminal 200. Note that an application for watching over the watching target 105 may be referred to as a watching app.

[0053] The monitoring app is, for example, a mobile application. The monitoring app is, for example, a web application. The monitoring app is, for example, a hybrid application.

Fig. 1 shows an example of display screen 220 that displays icon 225 indicating the location of mobile terminal 100 superimposed on map data.

[0057] For example, communication terminal 200 transmits various types of data. For example, communication terminal 200 transmits schedule data for the operation mode of mobile terminal 100. For example, communication terminal 200 transmits the schedule data for the operation mode of mobile terminal 100 in response to generating the schedule data for the operation mode of mobile terminal 100.

[0058] For example, communication terminal 200 instructs mobile terminal 100. For example, communication terminal 200 instructs mobile terminal 100 to set the operation mode of mobile terminal 100. For example, communication terminal 200 instructs mobile terminal 100 to set the operation mode of mobile terminal 100 to normal mode or power saving mode, based on schedule data of the operation mode of mobile terminal 100 and terminal status data indicating the terminal status of mobile terminal 100.

[0059] For example, the communication terminal 200 controls various functions installed in the communication terminal 200. For example, the communication terminal 200 controls the call function of the communication terminal 200. For example, the communication terminal 200 controls the call function of the communication terminal 200 so that a call is established between the communication terminal 200 and the mobile terminal 100.

The management device 300 communicates with, for example, a communication target of the management device 300 via the network 20. The management device 300 communicates with, for example, a communication target of the management device 300 via the network 20 and a wireless base station 30. Here, the mobile terminal 100 and the communication terminal 200 are shown as examples of the communication target of the management device 300.

[0062] The management device 300 receives, for example, various types of data. The management device 300 receives, for example, location data of the mobile terminal 100.

[0063] The management device 300 transmits, for example, various types of data, such as location data of the mobile terminal 100.

[0064] 2 is an explanatory diagram illustrating an example in which the watching target 105 makes a phone call using the mobile terminal 100. In this case, it is assumed that the parents of the watching target 105, who is a child, are the watchers 205.

[0065] The mobile terminal 100 includes, for example, a display screen 120. The mobile terminal 100 includes, for example, a button 140. The mobile terminal 100 includes, for example, a button 150.

[0066] The mobile terminal 100 registers, for example, phone book data. The phone book data may be composed of one or more pieces of contact data. The contact data includes, for example, registered name data indicating a registered name and phone number data indicating a phone number corresponding to the registered name. The contact data further includes, for example, email address data indicating an email address corresponding to the registered name. Here, the description will be continued assuming that the mobile terminal 100 has registered phone book data configured of contact data for the mother of the watching target 105, which includes registered name data for the registered name "Mom" and phone number data for the phone number of the communication terminal 200 owned by the mother of the watching target 105, who is the watcher 205, and contact data for the father of the watching target 105, which includes registered name data for the registered name "Dad" and phone number data for the phone number of the communication terminal 200 owned by the father of the watching target 105, who is the watcher 205.

[0067] The display screen 120 displays various data. For example, the display screen 120 displays contact data constituting the phone book data stored in the mobile terminal 100. For example, the display screen 120 displays registered name data included in the contact data. The display screen 120 may also display time data indicating the current time.

[0068] The buttons 140 are buttons for selecting data to be displayed on the display screen 120. Fig. 2 shows an example in which the mobile terminal 100 is provided with two buttons 140. The buttons 140 may be an example of a reception unit of the mobile terminal 100.

[0069] Button 150 is a button related to a call on mobile terminal 100. For example, when a call on mobile terminal 100 has not been established, button 150 is a button for starting the call. On the other hand, when a call on mobile terminal 100 has been established, button 150 is a button for ending the call. Note that button 150 may be an example of a reception unit of mobile terminal 100.

[0070] The upper diagram of Fig. 2 is an explanatory diagram illustrating an example of a case where the watched-over target 105 makes a call to the watcher 205 by making a call using the mobile terminal 100. Here, the watched-over target 105 is the caller and the mother of the watched-over target 105 is the callee.

[0071] For example, the watching target 105 presses button 140 so that the registered name "Mom," which is indicated by the registered name data included in the contact data of the mother of the watching target 105, is displayed on the display screen 120. Next, the watching target 105 presses button 150 while "Mom" is displayed on the display screen 120. In response to the button 150 being pressed while "Mom" is displayed on the display screen 120, the mobile terminal 100 makes a call to the telephone number indicated by the telephone number data included in the contact data of the mother of the watching target 105. Thereafter, the mother of the watching target 105 answers the incoming call from the mobile terminal 100 using the communication terminal 200 of the mother of the watching target 105. As a result, a call is established between the mobile terminal 100 and the communication terminal 200 of the mother of the watching target 105, and the watching target 105 can make a call to the mother of the watching target 105.

[0072] The lower diagram of Fig. 2 is an explanatory diagram illustrating an example in which the watched over target 105 makes a phone call with the watcher 205 by answering an incoming call using the mobile terminal 100. Here, it is assumed that the father of the watched over target 105 is the caller and the watched over target 105 is the callee.

[0073] For example, in response to an incoming call from the communication terminal 200 of the father of the watching target 105 being received at the mobile terminal 100, the mobile terminal 100 displays the registered name "Dad" indicated by the registered name data included in the contact data of the father of the watching target 105 on the display screen 120. After that, the watching target 105 confirms that "Dad" is displayed on the display screen 120 and responds to the incoming call from the communication terminal 200 of the father of the watching target 105 by pressing the button 150 using the mobile terminal 100. This establishes a call between the mobile terminal 100 of the watching target 105 and the communication terminal 200 of the father of the watching target 105, so that the watching target 105 can make a call with the father of the watching target 105.

[0074] 3 is an explanatory diagram illustrating an example of the flow of processing in the system 10. Here, the description will be given assuming that the state in which no phonebook data is registered in the mobile terminal 100 is the starting state.

[0075] In step (step may be abbreviated as S) 102, communication terminal 200 accepts input of phone book data to be registered in mobile terminal 100. In S104, communication terminal 200 transmits the phone book data accepted in S102 to management device 300. In S106, mobile terminal 100 receives from management device 300 the phone book data transmitted by management device 300 in S104. In S108, mobile terminal 100 registers the phone book data received in S106.

[0076] In S110, mobile terminal 100 measures the position of mobile terminal 100. In S112, mobile terminal 100 transmits position data indicating the position of mobile terminal 100 measured in S110 to management device 300. In S114, management device 300 transmits the position data of mobile terminal 100 received in S112 to communication terminal 200. Communication terminal 200 may display the position data of mobile terminal 100 received from management device 300 on display screen 220.

[0077] In S116, mobile terminal 100 accepts the pressing of button 140 and selects registered name data to be displayed on display screen 120 from the registered name data included in each of the multiple contact data constituting the phone book data registered in S108. Here, the explanation will continue assuming that registered name data included in contact data including telephone number data indicating the telephone number of communication terminal 200 has been selected.

[0078] In S118, mobile terminal 100 accepts pressing of button 150 while displaying the registered name data selected in S116 on display screen 120. In S120, mobile terminal 100 makes a call to the telephone number of communication terminal 200 in response to accepting the pressing of button 150 in S118.

[0079] In S122, in response to the call made by mobile terminal 100 in S120 being received by communication terminal 200, communication terminal 200 responds to the incoming call from mobile terminal 100. As a result, in S124, a call is established between mobile terminal 100 and communication terminal 200.

[0080] In S126, the mobile terminal 100 accepts the pressing of the button 150. This ends the call between the mobile terminal 100 and the communication terminal 200 that was established in S124.

[0081] In an example of a processing flow of the system 10 shown in FIG. 3, the communication terminal 200 transmits the phone book data to the mobile terminal 100 via the management device 300. The communication terminal 200 may transmit the phone book data directly to the mobile terminal 100. For example, the communication terminal 200 transmits the phone book data directly to the mobile terminal 100 via direct wireless communication. Here, the Wi-Fi (registered trademark) communication method, the Bluetooth (registered trademark) communication method, and the Zigbee (registered trademark) communication method are shown as examples of communication methods to which the direct wireless communication conforms. The communication terminal 200 may transmit the phone book data directly to the mobile terminal 100 via wired communication.

[0082] 3, management device 300 transmits the location data of mobile terminal 100 to communication terminal 200 in response to receiving the location data of mobile terminal 100 from mobile terminal 100. Management device 300 may transmit the location data of mobile terminal 100 to communication terminal 200 in response to receiving a transmission request from communication terminal 200 requesting transmission of the location data of mobile terminal 100.

[0083] 4 shows an example of the display screen 220 of the communication terminal 200. Here, an example of the display screen 220 when setting the operation mode of the mobile terminal 100 will be mainly described.

[0084] Communication terminal 200 generates, for example, schedule data for the operation modes of mobile terminal 100. Communication terminal 200 receives, for example, an input for scheduling the operation modes of mobile terminal 100, and generates schedule data for the operation modes of mobile terminal 100 based on the received input.

[0085] For example, the communication terminal 200 generates schedule data for the operation mode of the mobile terminal 100 for each day of the week. For example, the communication terminal 200 generates schedule data for the operation mode of the mobile terminal 100 for each date.

[0086] For example, communication terminal 200 generates schedule data that schedules the operation mode of mobile terminal 100 in units of hours. For example, communication terminal 200 generates schedule data that schedules the operation mode of mobile terminal 100 in units of hours. Communication terminal 200 may also generate schedule data that schedules the operation mode of mobile terminal 100 in any other time unit. Fig. 4 shows an example of display screen 220 when communication terminal 200 generates schedule data for the operation mode of mobile terminal 100 for each day of the week, such that the operation mode of mobile terminal 100 is scheduled to be normal mode from 8:00 to 18:00 Monday to Saturday, and the operation mode of mobile terminal 100 is scheduled to be power saving mode otherwise.

[0087] In response to receiving a press of button 250, communication terminal 200 may generate schedule data for the operation mode of mobile terminal 100. Thereafter, communication terminal 200 may transmit the generated schedule data for the operation mode of mobile terminal 100.

[0088] For example, communication terminal 200 transmits schedule data of the operation mode of mobile terminal 100 to management device 300. In this case, management device 300 may transmit the schedule data of the operation mode of mobile terminal 100 received from communication terminal 200 to mobile terminal 100. Communication terminal 200 may transmit the schedule data of the operation mode of mobile terminal 100 directly to mobile terminal 100.

[0089] Mobile terminal 100 may store the received schedule data of the operation mode of mobile terminal 100 in response to receiving the schedule data of the operation mode of mobile terminal 100 transmitted by communication terminal 200. As a result, mobile terminal 100 sets the operation mode of mobile terminal 100 based on the schedule data of the operation mode of mobile terminal 100.

[0090] 5 is an explanatory diagram illustrating an example of the flow of processing in the mobile terminal 100. Here, the description will be given assuming that the mobile terminal 100 is in a state where it stores schedule data for the operation mode of the mobile terminal 100 as a starting state.

[0091] In S202, the mobile terminal 100 acquires terminal status data of the mobile terminal 100. In S204, the mobile terminal 100 determines whether the operation mode of the mobile terminal 100 in the schedule data corresponding to the timing at which the operation mode of the mobile terminal 100 is set is scheduled to be the power saving mode. For example, if the schedule data schedules the operation mode of the mobile terminal 100 in one-hour increments and the timing at which the operation mode of the mobile terminal 100 is set is 3:00 PM, the mobile terminal 100 determines whether the operation mode of the mobile terminal 100 from 3:00 PM to 4:00 PM in the schedule data is scheduled to be the power saving mode.

[0092] If the mobile terminal 100 determines that the operation mode of the mobile terminal 100 in the schedule data is scheduled to be the power saving mode, the process proceeds to S206. If the mobile terminal 100 determines that the operation mode of the mobile terminal 100 in the schedule data is not scheduled to be the power saving mode, the process proceeds to S210.

[0093] In S206, the mobile terminal 100 determines whether the terminal state of the mobile terminal 100 indicated by the terminal state data of the mobile terminal 100 acquired by the mobile terminal 100 in S202 satisfies predetermined power saving conditions. If the mobile terminal 100 determines that the terminal state of the mobile terminal 100 satisfies the power saving conditions, the process proceeds to S208. If the mobile terminal 100 determines that the terminal state of the mobile terminal 100 does not satisfy the power saving conditions, the process proceeds to S210.

[0094] The power saving condition includes, for example, that the terminal state of the mobile terminal 100 is a stationary state. The power saving condition includes, for example, that the remaining battery charge of the battery mounted on the mobile terminal 100 is less than a predetermined remaining battery charge threshold, and that the terminal state of the mobile terminal 100 is a stationary state.

[0095] The power saving condition includes, for example, that the terminal state of the mobile terminal 100 is in a non-charging state. The power saving condition includes, for example, that the remaining battery charge of the battery mounted on the mobile terminal 100 is less than the remaining battery charge threshold, and that the terminal state of the mobile terminal 100 is in a non-charging state.

[0096] The power saving condition includes, for example, the terminal state of the mobile terminal 100 being both a stationary state and a non-charging state. The power saving condition includes, for example, the remaining battery charge of the battery mounted on the mobile terminal 100 being less than the remaining battery charge threshold, and the terminal state of the mobile terminal 100 being both a stationary state and a non-charging state. Note that the terminal state of the mobile terminal 100 being both a stationary state and a non-charging state may mean that the terminal state of the mobile terminal 100 is both a stationary state and a non-charging state.

[0097] In S208, the mobile terminal 100 sets the operation mode of the mobile terminal 100 to the power saving mode. For example, the mobile terminal 100 sets the operation mode of the mobile terminal 100 to the power saving mode by switching the operation mode of the mobile terminal 100 from the normal mode to the power saving mode. For example, the mobile terminal 100 sets the operation mode of the mobile terminal 100 to the power saving mode by maintaining the operation mode of the mobile terminal 100 in the power saving mode. Note that switching the operation mode and maintaining the operation mode may each be an example of setting the operation mode.

[0098] In S210, the mobile terminal 100 sets the operation mode of the mobile terminal 100 to the normal mode. The mobile terminal 100 may set the operation mode of the mobile terminal 100 to the normal mode in the same manner as when the operation mode of the mobile terminal 100 is set to the power saving mode.

[0099] In S212, if the mobile terminal 100 has not received the end instruction, the process returns to S202. In S212, if the mobile terminal 100 has received the end instruction, the process then ends.

[0100] As mentioned above, there has been a growing need recently for mobile devices equipped with a positioning function carried by children or other monitored individuals to be equipped with a calling function so that they can make phone calls to the monitored individuals while they are out. However, these mobile devices require power for the calling function in addition to the power for the positioning function. Furthermore, since a session must be maintained in order to use the calling function, a large amount of power is required to use the calling function. As a result, the power consumption of the mobile device equipped with the calling function increases significantly. This increased power consumption of the mobile device means a higher risk of the mobile device running out of battery power while the monitored individual is out, making it impossible for the monitor to monitor the monitored individual. Because the monitor has the monitored individual carry the mobile device in order to monitor the monitored individual, it is essential to avoid the mobile device's battery running out while the monitored individual is out as much as possible.

[0101] On the other hand, the people being watched over, who are the owners of the mobile devices, are mainly children, elderly people, etc. Therefore, if a large-capacity, heavy battery is installed in the mobile device as a countermeasure against the battery running out of the mobile device while the person being watched over is out, the person being watched over may feel burdened by carrying the mobile device, which may degrade the user experience of the person being watched over. Furthermore, considering that the people being watched over who are the owners of the mobile devices are mainly children, elderly people, etc., it is expected that the person being watched over will charge the mobile device. Therefore, an increase in the power consumption of the mobile device will increase the frequency at which the person being watched over will charge the mobile device, which may degrade the user experience of the person being watched over. For these reasons, it is desirable to be able to extend the battery life of the mobile device while preventing a degradation in the user experience.

[0102] In contrast, according to the system 10 of this embodiment, the mobile terminal 100 carried by the watcher 205 is equipped with a positioning function and a call function. The mobile terminal 100 establishes a call between the mobile terminal 100 and the communication terminal 200 carried by the watcher 205. The mobile terminal 100 then sets the operation mode of the mobile terminal 100 to the normal mode or the power saving mode based on schedule data of the operation mode of the mobile terminal 100 stored in the mobile terminal 100 and terminal status data of the mobile terminal 100 acquired by the mobile terminal 100. For example, the mobile terminal 100 sets the operation mode of the mobile terminal 100 to the power saving mode when the operation mode of the mobile terminal 100 in the schedule data corresponding to the timing at which the operation mode of the mobile terminal 100 is to be set is scheduled to be the power saving mode, and the terminal status of the mobile terminal 100 satisfies the power saving condition. On the other hand, if the operation mode of mobile terminal 100 in the schedule data corresponding to that timing is scheduled to be normal mode, or if the terminal state of mobile terminal 100 does not satisfy the power saving conditions, mobile terminal 100 sets the operation mode of mobile terminal 100 to normal mode. Since mobile terminal 100 can flexibly set the operation mode of mobile terminal 100 in accordance with the terminal state of mobile terminal 100 while taking into consideration the scheduling of the operation mode of mobile terminal 100 indicated by the schedule data, system 10 according to this embodiment can appropriately reduce the power consumption of a mobile terminal equipped with a positioning function and a call function.

[0103] Furthermore, according to the system 10 of this embodiment, the power consumption of the mobile terminal 100 can be appropriately reduced by flexibly setting the operation mode of the mobile terminal 100 according to the scheduling of the operation mode of the mobile terminal 100 and the terminal state of the mobile terminal 100, so that the mobile terminal 100 can be equipped with a relatively lightweight battery while achieving an extended battery life. As a result, the mobile terminal 100 can achieve both a reduced weight and an extended battery life, so the system 10 of this embodiment can achieve an extended battery life for a mobile terminal equipped with a positioning function and a call function while preventing a degradation in the user experience of the monitored target.

[0104] Furthermore, according to the system 10 of this embodiment, the communication terminal 200 carried by the watcher 205 acquires location data of the mobile terminal 100 carried by the watchee 105 of the watcher 205, and establishes a call between the communication terminal 200 and the mobile terminal 100. The communication terminal 200 generates schedule data for the operation mode of the mobile terminal 100 and transmits the generated schedule data to the mobile terminal 100. Then, based on the schedule data and the terminal status data of the mobile terminal 100, the communication terminal 200 instructs the mobile terminal 100 to set the operation mode of the mobile terminal 100 to a normal mode or a power saving mode. The mobile terminal 100 can flexibly set the operation mode of the mobile terminal 100 depending on the terminal status of the mobile terminal 100 in accordance with the instruction from the communication terminal 200. Therefore, the system 10 of this embodiment can appropriately reduce the power consumption of a mobile terminal equipped with a positioning function and a call function.

[0105] Furthermore, according to the system 10 of this embodiment, the communication terminal 200 can remotely schedule the operation mode of the mobile terminal 100 by transmitting the schedule data to the mobile terminal 100. Therefore, the watcher 205 can extend the battery life of the mobile terminal 100 simply by using the communication terminal 200 to schedule the operation mode of the mobile terminal 100. This allows the watcher 205 to extend the battery life of the mobile terminal 100 with little burden on the watcher 205 and reduce the frequency of charging the mobile terminal 100. Therefore, the system 10 of this embodiment can extend the battery life of a mobile terminal equipped with a positioning function and a calling function while preventing a deterioration in the user experience of the watcher.

[0106] As described above, the system 10 according to the present embodiment can extend the battery life of a mobile device equipped with a positioning function and a calling function while preventing degradation of the user experience. This can increase the motivation of the person watching over the mobile device to be used by the person being watched over, ultimately leading to a society in which mobile devices are widely used. As a result, the system 10 according to the present embodiment can contribute to the realization of a society in which all people, including children and the elderly, can live in peace of mind.

[0107] 6 is an explanatory diagram illustrating an example of setting the operation mode of the mobile terminal 100. Here, it is assumed that the power saving condition is that the terminal state of the mobile terminal 100 is both a stationary state and a non-charging state.

[0108] The schedule data for the operation modes of the mobile terminal 100 schedules the operation modes of the mobile terminal 100 in one-hour units, for example. Fig. 6 shows an example of schedule data for the operation modes of the mobile terminal 100 that schedules the operation mode of the mobile terminal 100 to be "normal mode" in the time zone from "07:00" to "09:00" and schedules the operation mode of the mobile terminal 100 to be "power saving mode" in the time zones from "06:00" to "07:00" and "09:00" to "13:00".

[0109] The mobile terminal 100 sets the operation mode of the mobile terminal 100 within a predetermined setting period, for example. The mobile terminal 100 sets the operation mode of the mobile terminal 100 within the setting period by, for example, determining the timing at which the operation mode of the mobile terminal 100 is set within the setting period and setting the operation mode of the mobile terminal 100 at the determined timing. The mobile terminal 100 randomly determines the timing at which the operation mode of the mobile terminal 100 is set within the setting period, for example. Note that the setting period is referred to as P S It may be written as follows.

[0110] For example, when the current operation mode of mobile terminal 100 is scheduled to be the normal mode, the start time of the set period of mobile terminal 100 is the start time of the next scheduled operation mode of mobile terminal 100. For example, if the length of the set period of mobile terminal 100 is 5 minutes, when the current operation mode of mobile terminal 100 is scheduled to be the normal mode and the start time of the next scheduled operation mode of mobile terminal 100 is 20:00, the set period of mobile terminal 100 will be 20:00 to 20:05.

[0111] For example, when the current operation mode of mobile terminal 100 is scheduled to be the power saving mode, the end time of the set period of mobile terminal 100 is the start time of the next scheduled operation mode of mobile terminal 100. For example, if the length of the set period of mobile terminal 100 is 5 minutes, when the current operation mode of mobile terminal 100 is scheduled to be the power saving mode and the start time of the next scheduled operation mode of mobile terminal 100 is 20:00, the set period of mobile terminal 100 will be from 19:55 to 20:00.

[0112] The end time of the set period of mobile terminal 100 when the current operation mode of mobile terminal 100 is scheduled to be the normal mode may be the start time of the next scheduled operation mode of mobile terminal 100. Furthermore, the start time of the set period of mobile terminal 100 when the current operation mode of mobile terminal 100 is scheduled to be the power saving mode may be the start time of the next scheduled operation mode of mobile terminal 100.

[0113] Here, an example will be described in which mobile terminal 100 sets the operation mode of mobile terminal 100 based on the schedule data of the operation mode of mobile terminal 100 shown in Fig. 6 and the terminal status data of mobile terminal 100. Here, the state in which mobile terminal 100's operation mode at 06:00 is the power saving mode is set as the starting state.

[0114] In the example shown in Fig. 6, the start time of the next scheduled operation mode of mobile terminal 100 is the start time of the set period of mobile terminal 100 when the current operation mode of mobile terminal 100 is scheduled to be the normal mode, and the end time of the set period of mobile terminal 100 when the current operation mode of mobile terminal 100 is scheduled to be the power saving mode. Also, it is assumed that the length of the set period of mobile terminal 100 is 5 minutes. Note that the length of the set period of mobile terminal 100 is not limited to 5 minutes, and may be longer than 5 minutes, such as 10 minutes, or shorter than 5 minutes, such as 3 minutes. In other words, the length of the set period of mobile terminal 100 may be any length.

[0115] The operation mode of the mobile terminal 100 from 06:00 to 07:00 is set to the power saving mode. SThe time t1 within the time range is randomly determined, and the operation mode of the mobile terminal 100 is set at time t1. Here, the terminal state of the mobile terminal 100 at time t1 is "stationary state" and "non-charging state", but the operation mode of the mobile terminal 100 for "07:00 to 08:00" on the schedule data corresponding to time t1 is scheduled to be "normal mode", so the mobile terminal 100 sets the operation mode of the mobile terminal 100 to "normal mode" at time t1.

[0116] The mobile terminal 100 is connected to the P S The time t2 within the time range is randomly determined, and the operation mode of the mobile terminal 100 is set at time t2. Here, the terminal state of the mobile terminal 100 at time t2 is "moving state" and "non-charging state", and the operation mode of the mobile terminal 100 for "08:00 to 09:00" on the schedule data corresponding to time t2 is scheduled to be "normal mode", so the mobile terminal 100 sets the operation mode of the mobile terminal 100 to "normal mode" at time t2.

[0117] The mobile terminal 100 is connected to the P S Time t3 within the set period is randomly determined, and the operation mode of mobile terminal 100 is set at time t3. Here, the terminal state of mobile terminal 100 at time t3 is "stationary state" and "non-charging state", and the operation mode of mobile terminal 100 for "09:00 to 10:00" on the schedule data corresponding to time t3 is scheduled to be "power saving mode", so mobile terminal 100 sets the operation mode of mobile terminal 100 to "power saving mode" at time t3. Here, the explanation will continue assuming that the terminal state of mobile terminal 100 does not change from time t3 until the start time of the next set period of mobile terminal 100.

[0118] The mobile terminal 100 is set to P SThe time t4 within the time range is randomly determined, and the operation mode of the mobile terminal 100 is set at time t4. Here, the terminal state of the mobile terminal 100 at time t4 is "stationary state" and "non-charging state", and the operation mode of the mobile terminal 100 for "10:00 to 11:00" on the schedule data corresponding to time t4 is scheduled to be "power saving mode", so the mobile terminal 100 sets the operation mode of the mobile terminal 100 to "power saving mode" at time t4.

[0119] At time t', which is a time from time t4 to before 10:55, the start time of the next set period of mobile terminal 100, the terminal state of mobile terminal 100 changes to "moving state" and "non-charging state." If the operation mode of mobile terminal 100 is set to power saving mode and the terminal state of mobile terminal 100 no longer satisfies the power saving conditions, mobile terminal 100 sets the operation mode to normal mode. Therefore, mobile terminal 100 sets the operation mode of mobile terminal 100 to "normal mode" at time t'.

[0120] The mobile terminal 100 is set to P S The time t5 within the time range is randomly determined, and the operation mode of the mobile terminal 100 is set at time t5. Here, the operation mode of the mobile terminal 100 for "11:00 to 12:00" on the schedule data corresponding to time t5 is scheduled to be "power saving mode", but since the terminal state of the mobile terminal 100 at time t5 is "moving state" and "non-charging state", the mobile terminal 100 sets the operation mode of the mobile terminal 100 to "normal mode" at time t5.

[0121] The mobile terminal 100 is set to P SThe time t6 within the time range is randomly determined, and the operation mode of the mobile terminal 100 is set at time t6. Here, the terminal state of the mobile terminal 100 at time t6 is "stationary state" and "non-charging state", and the operation mode of the mobile terminal 100 for "11:00 to 12:00" on the schedule data corresponding to time t6 is scheduled to be "power saving mode", so the mobile terminal 100 sets the operation mode of the mobile terminal 100 to "power saving mode" at time t6.

[0122] Thereafter, mobile terminal 100 sets the operation mode of mobile terminal 100 from time t6 onward in the same manner as the above-described method for setting the operation mode of mobile terminal 100. As a result, mobile terminal 100 sets the operation mode of mobile terminal 100 based on the schedule data of the operation mode of mobile terminal 100 and the terminal state data of mobile terminal 100.

[0123] When switching the operation mode of a mobile terminal equipped with positioning and communication functions from normal mode to power saving mode, if the communication function of the mobile terminal is active in normal mode and inactive in power saving mode, the mobile terminal deactivates the communication function after terminating the session. Therefore, when switching the operation mode from normal mode to power saving mode, the mobile terminal needs to communicate with a wireless base station to terminate the session. Similarly, when switching the operation mode from power saving mode to normal mode, the mobile terminal needs to communicate with a wireless base station to establish a session. However, if multiple mobile terminals simultaneously communicate with a wireless base station to terminate or establish a session, the amount of traffic at the wireless base station may increase, which may cause congestion at the wireless base station.

[0124] In contrast to this, according to the mobile terminal 100 shown in Fig. 6, the mobile terminal 100 randomly determines the timing at which the operation mode of the mobile terminal 100 is set within a set period based on the schedule data of the operation mode of the mobile terminal 100, and sets the operation mode of the mobile terminal 100 at the randomly determined timing. This makes it possible to distribute the timing at which each of the multiple mobile terminals 100 communicates with the wireless base station 30 to terminate or establish a session, so the mobile terminal 100 shown in Fig. 6 can set the operation mode to the normal mode or the power saving mode while reducing the possibility of congestion occurring in the wireless base station.

[0125] 7 is an explanatory diagram illustrating another example of the processing flow of mobile terminal 100. Here, the description will be given assuming that the mobile terminal 100 is in a starting state where it has not yet acquired acceleration data indicating the acceleration of mobile terminal 100 measured by an acceleration sensor mounted on mobile terminal 100. The acceleration data of mobile terminal 100 may be an example of terminal state data of mobile terminal 100.

[0126] In S302, the mobile terminal 100 acquires acceleration data of the mobile terminal 100. The acceleration of the mobile terminal 100 indicated by the acceleration data of the mobile terminal 100 may be referred to as α.

[0127] In S304, the mobile terminal 100 determines whether α is smaller than a predetermined first acceleration threshold. TH1 It may be written as follows.

[0128] α is α TH1 If the mobile terminal 100 determines that α is smaller than α, the process proceeds to S310. TH1 If the mobile terminal 100 determines that it is larger, the process proceeds to S306.

[0129] In S306, the mobile terminal 100 determines whether α is α TH1 It is determined whether the acceleration is smaller than a second acceleration threshold value that is larger than the first acceleration threshold value. TH2 It may be written as follows.

[0130] α is α TH2 If the mobile terminal 100 determines that α is smaller than α, the process proceeds to S308. TH2 If the mobile terminal 100 determines that it is larger, the process proceeds to S312.

[0131] In S308, the mobile terminal 100 determines whether α is equal to or smaller than α for a predetermined duration. TH2 It is determined whether the terminal state of the mobile terminal 100 smaller than the threshold value continues. During this continuation period, α is equal to or smaller than α TH2 If the mobile terminal 100 determines that the terminal state of the mobile terminal 100 is smaller than the threshold value, the process proceeds to S310. TH2 If the mobile terminal 100 determines that the terminal state of the smaller mobile terminal 100 is not continuing, the process proceeds to S312.

[0132] In S310, the mobile terminal 100 determines that the mobile terminal 100 is in a stationary state. In S312, the mobile terminal 100 determines that the mobile terminal 100 is in a non-stationary state.

[0133] In S314, if the mobile terminal 100 has not received the end instruction, the process returns to S302. In S314, if the mobile terminal 100 has received the end instruction, the process then ends.

[0134] 7, the mobile terminal 100 determines whether the mobile terminal itself is in a stationary state based on the magnitude of α. For example, when α is α TH1 If α is smaller than α for the duration, or TH2 If the terminal state of the mobile terminal 100 is smaller than the above, the mobile terminal 100 determines that it is in a stationary state. TH2 If α is greater than α for that duration, TH2If the terminal state of mobile terminal 100 is smaller than the above, mobile terminal 100 determines that it is not stationary. By mobile terminal 100 determining in stages whether it is stationary or not based on the size of α, mobile terminal 100 can determine with high accuracy whether the terminal state of mobile terminal 100 is stationary or not. This allows mobile terminal 100 shown in FIG. 7 to more appropriately set its operating mode to normal mode or power saving mode.

[0135] 8 shows an example of the functional configuration of the mobile terminal 100. The mobile terminal 100 may include a storage unit 102, an acquisition unit 104, a transmission unit 106, a control unit 108, a setting unit 112, and a reception unit 114. It is not essential that the mobile terminal 100 include all of these components.

[0136] The storage unit 102 stores various types of data. For example, the storage unit 102 stores phone book data of the mobile terminal 100. For example, the storage unit 102 stores schedule data of the operation modes of the mobile terminal 100.

[0161] Setting unit 112 sets the operation mode of mobile terminal 100 within a predetermined setting period, for example. Setting unit 112 sets the operation mode of mobile terminal 100 within the setting period by, for example, determining the timing at which the operation mode of mobile terminal 100 is set within the setting period and setting the operation mode of mobile terminal 100 at that timing. Setting unit 112 determines the timing randomly within the setting period, for example.

[0162] For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode. For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode and the terminal state of mobile terminal 100 indicated by the terminal state data of mobile terminal 100 satisfies predetermined power saving conditions, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode.

[0163] Setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode and the terminal state of mobile terminal 100 is a stationary state. Setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode, the remaining battery level of the battery installed in mobile terminal 100 indicated by the remaining battery level data of mobile terminal 100 is less than a predetermined remaining battery level threshold, and the terminal state of mobile terminal 100 is a stationary state.

[0164] For example, setting unit 112 determines that mobile terminal 100 is in a stationary state when the acceleration of mobile terminal 100 indicated by the acceleration data of mobile terminal 100 is smaller than a predetermined acceleration threshold. For example, setting unit 112 determines that mobile terminal 100 is in a stationary state when the terminal state of mobile terminal 100 in which the acceleration of mobile terminal 100 indicated by the acceleration data of mobile terminal 100 is smaller than a predetermined acceleration threshold continues for a predetermined duration.

[0165] For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode and the terminal state of mobile terminal 100 is in a non-charging state, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode. For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode, the remaining battery level of the battery mounted in mobile terminal 100 is less than the remaining battery level threshold, and the terminal state of mobile terminal 100 is in a non-charging state, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode.

[0166] For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode, and the terminal state of mobile terminal 100 is both a stationary state and a non-charging state, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode. For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode, the remaining battery level of the battery mounted on mobile terminal 100 is less than the remaining battery level threshold, and the terminal state of mobile terminal 100 is both a stationary state and a non-charging state, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode.

[0167] On the other hand, if the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be normal mode, setting unit 112 sets the operation mode of the mobile terminal to normal mode. For example, if the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be normal mode, or if the terminal state of mobile terminal 100 does not satisfy a predetermined power saving condition, setting unit 112 sets the operation mode of the mobile terminal to normal mode.

[0168] Setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, or when the terminal state of mobile terminal 100 is a non-stationary state. Setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, when the remaining battery level of the battery mounted on mobile terminal 100 is greater than the remaining battery level threshold, or when the terminal state of mobile terminal 100 is a non-stationary state.

[0169] For example, when the acceleration of mobile terminal 100 is greater than a predetermined acceleration threshold, setting unit 112 determines that mobile terminal 100 is in a non-stationary state. For example, when the terminal state of mobile terminal 100 in which the acceleration of mobile terminal 100 is less than a predetermined acceleration threshold does not continue during the continuation period, setting unit 112 determines that mobile terminal 100 is in a non-stationary state.

[0170] Setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, or when the terminal state of mobile terminal 100 is in a charging state. Setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, when the remaining battery level of the battery mounted on mobile terminal 100 is greater than the remaining battery level threshold, or when the terminal state of mobile terminal 100 is in a charging state.

[0171] Setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, or when the terminal state of mobile terminal 100 is at least one of a non-stationary state and a charging state. Setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode, for example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, when the remaining battery level of the battery mounted on mobile terminal 100 is greater than the remaining battery level threshold, or when the terminal state of mobile terminal 100 is at least one of a non-stationary state and a charging state.

[0174] For example, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the power saving mode and reception unit 114 has not received an input for using the call function of mobile terminal 100, setting unit 112 sets the operation mode of mobile terminal 100 to the power saving mode. On the other hand, when the operation mode of mobile terminal 100 in the schedule data corresponding to the timing is scheduled to be the normal mode, or when reception unit 114 has received an input for using the call function of mobile terminal 100, setting unit 112 sets the operation mode of mobile terminal 100 to the normal mode.

[0209] 11 schematically illustrates an example of the hardware configuration of a computer 1200 functioning as the mobile terminal 100, the communication terminal 200, or the management device 300. A program installed on the computer 1200 can cause the computer 1200 to function as one or more "units" of an apparatus according to the present embodiment, or can cause the computer 1200 to execute operations associated with the apparatus according to the present embodiment or one or more "units," and / or can cause the computer 1200 to execute a process according to the present embodiment or steps of the process. Such a program can be executed by the CPU 1212 to cause the computer 1200 to perform specific operations associated with some or all of the blocks in the flowcharts and block diagrams described herein.

[0210] The computer 1200 according to this embodiment includes a CPU 1212, a RAM 1214, and a graphics controller 1216, which are interconnected by a host controller 1210. The computer 1200 also includes input / output units such as a communications interface 1222, a storage device 1224, a DVD drive 1226, and an IC card drive, which are connected to the host controller 1210 via an input / output controller 1220. The DVD drive 1226 may be a DVD-ROM drive, a DVD-RAM drive, or the like. The storage device 1224 may be a hard disk drive, a solid-state drive, or the like. The computer 1200 also includes a ROM 1230 and legacy input / output units such as a keyboard, which are connected to the input / output controller 1220 via an input / output chip 1240.

[0211] The CPU 1212 operates according to programs stored in the ROM 1230 and the RAM 1214, thereby controlling each unit. The graphics controller 1216 acquires image data generated by the CPU 1212 into a frame buffer or the like provided in the RAM 1214 or into the graphics controller itself, and causes the image data to be displayed on the display device 1218.

[0212] The communication interface 1222 communicates with other electronic devices via a network. The storage device 1224 stores programs and data used by the CPU 1212 in the computer 1200. The DVD drive 1226 reads programs or data from a DVD-ROM 1227 or the like and provides them to the storage device 1224. The IC card drive reads programs and data from an IC card and / or writes programs and data to an IC card.

[0213] The ROM 1230 stores therein a boot program or the like that is executed by the computer 1200 upon activation, and / or programs that depend on the hardware of the computer 1200. The input / output chip 1240 may also connect various input / output units to the input / output controller 1220 via a USB port, a parallel port, a serial port, a keyboard port, a mouse port, etc.

[0214] The programs are provided by a computer-readable storage medium such as a DVD-ROM 1227 or an IC card. The programs are read from the computer-readable storage medium, installed in the storage device 1224, RAM 1214, or ROM 1230, which are also examples of computer-readable storage media, and executed by the CPU 1212. Information processing described in these programs is read by the computer 1200, and causes cooperation between the programs and the various types of hardware resources described above. An apparatus or method may be configured by implementing operations or processing of information in accordance with the use of the computer 1200.

[0215] For example, when communication is performed between the computer 1200 and an external device, the CPU 1212 may execute a communication program loaded into the RAM 1214 and instruct the communication interface 1222 to perform communication processing based on the processing described in the communication program. Under the control of the CPU 1212, the communication interface 1222 reads transmission data stored in a transmission buffer area provided in the RAM 1214, the storage device 1224, the DVD-ROM 1227, or a recording medium such as an IC card, and transmits the read transmission data to the network, or writes reception data received from the network to a reception buffer area or the like provided on the recording medium.

[0216] Furthermore, the CPU 1212 may cause all or a necessary portion of a file or database stored in an external recording medium such as the storage device 1224, the DVD drive 1226 (DVD-ROM 1227), an IC card, etc. to be read into the RAM 1214, and may perform various types of processing on the data on the RAM 1214. The CPU 1212 may then write back the processed data to the external recording medium.

[0217] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and may undergo information processing. The CPU 1212 may perform various types of processing on data read from the RAM 1214, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search / replacement, etc., as described throughout this disclosure and specified by the instruction sequences of the programs, and write the results back to the RAM 1214. The CPU 1212 may also search for information in a file, database, etc. on the recording medium. For example, if multiple entries, each having an attribute value of a first attribute associated with an attribute value of a second attribute, are stored on the recording medium, the CPU 1212 may search for an entry whose attribute value of the first attribute matches a specified condition from among the multiple entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0218] The above-described programs or software modules may be stored in a computer-readable storage medium on or near the computer 1200. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can also be used as a computer-readable storage medium, thereby providing the programs to the computer 1200 via the network.

[0219] The blocks in the flowcharts and block diagrams in the present embodiments may represent stages of a process in which an operation is performed or "parts" of an apparatus responsible for performing the operation. Particular stages and "parts" may be implemented by dedicated circuitry, programmable circuitry provided with computer-readable instructions stored on a computer-readable storage medium, and / or a processor provided with computer-readable instructions stored on a computer-readable storage medium. The dedicated circuitry may include digital and / or analog hardware circuits, including integrated circuits (ICs) and / or discrete circuits. The programmable circuitry may include reconfigurable hardware circuits, such as field programmable gate arrays (FPGAs) and programmable logic arrays (PLAs), including AND, OR, XOR, NAND, NOR, and other logical operations, flip-flops, registers, and memory elements.

[0220] A computer-readable medium may include any tangible device capable of storing instructions that are executed by a suitable device, such that the computer-readable medium having instructions stored thereon comprises an article of manufacture containing instructions that can be executed to create means for performing the operations specified in the flowcharts or block diagrams. Examples of computer-readable media may include electronic, magnetic, optical, electromagnetic, and semiconductor storage media. More specific examples of computer-readable media may include floppy disks, diskettes, hard disks, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), electrically erasable programmable read-only memory (EEPROM), static random access memory (SRAM), compact disc read-only memory (CD-ROM), digital versatile disc (DVD), Blu-ray disc, memory stick, integrated circuit card, and the like.

[0221] The computer readable instructions may include either assembler instructions, instruction set architecture (ISA) instructions, machine instructions, machine-dependent instructions, microcode, firmware instructions, state-setting data, or source or object code written in any combination of one or more programming languages, including object-oriented programming languages ​​such as Smalltalk®, JAVA®, C++, etc., and conventional procedural programming languages ​​such as the “C” programming language or similar programming languages.

[0222] The computer-readable instructions may be provided to a processor or programmable circuit of a programmable data processing device, such as a computer, locally or via a wide area network (WAN) such as a local area network (LAN) or the Internet, and the computer-readable instructions may be executed to create means for performing the operations specified in the flowcharts or block diagrams. Here, the computer may be a personal computer (PC), a tablet computer, a smartphone, a workstation, a server computer, a general-purpose computer, a special-purpose computer, or the like, or may be a computer system in which multiple computers are connected. Such a computer system in which multiple computers are connected is also called a distributed computing system, and is a broad definition of computer. In a distributed computing system, the multiple computers collectively execute a program by each executing a portion of the program and passing data between the computers as needed during program execution.

[0223] Examples of processors include a computer processor, a central processing unit (CPU), a processing unit, a microprocessor, a digital signal processor, a controller, a microcontroller, etc. A computer may have one or more processors. In a multiprocessor system with multiple processors, each processor executes a portion of a program and passes data between processors as needed during program execution, allowing the multiple processors to collectively execute the program. For example, in multitasking, each of the multiple processors may execute a portion of each task in small chunks by switching tasks at time slice intervals. In this case, which portion of a program each processor executes changes dynamically. Which portion of a program each of the multiple processors executes may also be statically determined by multiprocessor-aware programming.

[0224] This invention can contribute to the realization of a society where all people, including children and the elderly, can live in peace, and can therefore contribute to achieving Goal 11 of the Sustainable Development Goals (SDGs), "Sustainable cities and communities."
