  Hereinafter, a position providing system 1, a terminal device, a position acquisition method, and a position acquisition program according to an embodiment will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration of a position providing system 1 according to the embodiment. The location providing system 1 includes a plurality of terminal devices 10A, 10B,..., 10N (hereinafter simply referred to as “terminal device 10” when collectively referred to), a location information server 30, an authentication server 40, a POI (Point Of Interest) server 42 and application servers 50A, 50B,..., 50N (hereinafter simply referred to as “application server 50” when collectively referred to).

  The location providing system 1 transmits the location information of the terminal device 10 from the terminal device 10 to the location information server 30, and provides this location information from the location information server 30 to the application server 50. The terminal device 10 transmits position information at an arbitrary transmission timing or every predetermined period. In the present embodiment, an example in which position information is transmitted at a transmission timing determined in advance in the terminal device 10 will be described. However, the position information transmission timing of the terminal device 10 may be set by the position information server 30.

  The location information server 30 receives and accumulates location information transmitted from the terminal device 10. In this specific example, the location information server 30 accumulates location information in time series for each terminal device 10. Further, when the authentication server 40 performs application authentication processing of the terminal device 10, the location information server 30 may also accumulate identification information (ID) of applications that are permitted to be used in the terminal device 10. The location information server 30 transmits the accumulated location information to the POI server 42 and the application server 50.

  The application server 50 is a server device corresponding to each of a plurality of application programs installed in the terminal device 10. Here, a plurality of application programs selected from the application programs A to N can be installed in the terminal device 10. In the present embodiment, a case where application programs A to C are installed in the terminal device 10 will be described as an example. In this specific example, the application server 50 </ b> A is a server device corresponding to the application program A among a plurality of application programs installed in the terminal device 10. The application server 50B is a server device corresponding to the application program B among a plurality of application programs installed in the terminal device 10. The application server 50 </ b> C is a server device corresponding to the application program C among a plurality of application programs installed in the terminal device 10. The application server 50 receives the position information of the terminal device 10 via the position information server 30.

  The application server 50 performs predetermined application processing using the tracked location information of the terminal device 10. The tracked position information includes the latest position or past position of the terminal device 10 that is updated arbitrarily or repeatedly at predetermined intervals. This application process may include a process of analyzing a change in the position of the terminal device 10 and determining application information such as advertisement information suitable for the terminal device 10. The application information may be transmitted from the application server 50 to the terminal device 10. Thereby, the application server 50 can display an advertisement or the like suitable for the position of the terminal device 10 on the terminal device 10. In this example, the application information corresponds to information based on the position information acquired by the position information acquisition unit of the terminal device 10.

  The authentication server 40 performs various authentication processes when the terminal device 10 starts communication with the location information server 30. The authentication process performed by the authentication server 40 includes, for example, a terminal authentication process, a user authentication process, or an application authentication process. Specific examples of these authentication processes will be described. In the terminal authentication process, the authentication server 40 makes the authentication successful when the terminal ID transmitted from the terminal device 10 matches the terminal ID stored in advance. Here, the terminal ID is information such as a unique symbol or number for identifying the terminal device 10. The authentication server 40 in the user authentication process makes the authentication successful when the user ID transmitted from the terminal device 10 matches the user ID stored in advance. Here, the user ID is information such as a unique symbol or number for identifying a user who uses the terminal device 10. The authentication server 40 in the application authentication process makes the authentication successful when the application ID transmitted from the terminal device 10 matches the application ID stored in advance. Here, the application ID is information such as a unique symbol or number for identifying an application program that can be used in the terminal device 10.

  When the authentication by the authentication server 40 is successful, the authentication server 40 generates a token in the terminal device 10 and transmits it to the terminal device 10. The token transmitted from the authentication server 40 is stored in the terminal device 10. Thereby, the terminal device 10 can perform secure communication with the position information server 30 and the application server 50. Note that the token may be updated at an arbitrary timing. Thereby, the terminal device 10 can perform more secure communication.

  In addition, when the terminal device 10 is a mobile phone, the authentication server 40 may use an IP (Internet Protocol) address and a telephone number in the terminal authentication process. The authentication server 40 receives the IP address and telephone number transmitted from the terminal device 10 via the location information server 30. The authentication server 40 collates the received IP address and telephone number with a valid IP address and telephone number. If the received IP address and telephone number can be verified with a valid IP address and telephone number, the authentication server 40 transmits an authentication result permitting communication to the location information server 30.

The POI server 42 stores POI information. The POI information includes at least information indicating the latitude and longitude of a store or the like. When the POI server 42 receives a request including the position information of the terminal device 10 output from the terminal device 10, the position information server 30, or the application server 50, the POI information corresponding to the position information in response to the reception of this request. And POI information near the position information is returned. The POI information may include a location ID such as a store, a location name, and a category. As a result, the POI server 42 can return a location ID, a location name, a category, and the like corresponding to the position information as a search result.
The POI server 42 may search the terminal device 10 using the POI information as a key. As a result, the POI server 42 can extract the terminal device 10 corresponding to the POI information and send it back as a search result. For example, the POI server 42 can search for the terminal device 10 present in a certain store and send back the user ID of the terminal device 10.

  FIG. 2 is a block diagram illustrating a configuration of the terminal device 10 according to the embodiment. The terminal device 10 includes a processing unit 12, a communication unit 14, a GPS (Global Positioning System) positioning unit 16, and a storage unit 18. The terminal device 10 is a device that is owned and moved by a user. The terminal device 10 may be a mobile phone or a smartphone, for example.

The communication unit 14 communicates with the position information server 30. The communication unit 14 is configured by a communication IC chip, for example. The communication unit 14 converts the position information supplied from the processing unit 12 into predetermined communication data and transmits it to the position information server 30. This position information includes positioning time, latitude, and longitude.
When the authentication server 40 performs application authentication, the position information may include an application ID of an application permitted in the terminal device 10. When communication data is received from the position information server 30 or the application server 50, the communication unit 14 performs a predetermined process on the received communication data and outputs it to the processing unit 12.

The position information may include information related to the terminal device 10 such as a user ID, a terminal ID, a terminal model name, and an OS (Operating System) type. Further, the position information may include a positioning method of the position information and a positioning error of the position information measured by the positioning method. Examples of the positioning method include a GPS positioning method, a cell ID method, a Wi-Fi method, and a network positioning method. Furthermore, when the terminal device 10 exists in the Wi-Fi network, the location information may include the ID of the access point of the Wi-Fi network. Furthermore, when the terminal device 10 is communicating by starting the Bluetooth function, the position information may include an ID as a Bluetooth terminal.
Furthermore, the position information may include program execution history information related to a program executed by the terminal device 10 at the position indicated by the position information. The program execution history information includes the time when the terminal device 10 executes the program and the name and type of the executed program. The program execution history information includes the time when the program is started and the time when the program is restarted from the sleep state. The programs executed by the terminal device 10 include, for example, a camera program, a mail program, a telephone program, a music playback program (which may include a played music name, etc.), a calculator program, and the like.
Further, the position information may include web history information related to an access history to the web page accessed by the terminal device 10 at the position indicated by the position information and an operation history of the activated web browser. The web history information includes the time when the terminal device 10 accessed a corporate advertisement or a web page such as a home page and the address of the accessed web page.
Further, the position information may include operation history information related to an operation from the user received by the terminal device 10 at the position indicated by the position information. The operation history information includes the time when the terminal device 10 receives an operation and the name and type of the received operation. The operations received by the terminal device 10 include, for example, an operation to turn on the power, an operation to turn off the power, an operation to adjust the speaker volume, and an operation to switch to the power saving mode.
Furthermore, the position information may include posture change information indicating a change in the posture of the terminal device 10 at the position indicated by the position information. The posture change information includes the time when the posture of the terminal device 10 is changed. Note that the change in the attitude of the terminal device 10 is detected by an acceleration sensor or the like to be described later.

  Further, the position information may include environment information acquired by the terminal device 10 at the position indicated by the position information. The environmental information includes sound information collected by the terminal device 10, a communication history of near field communication, and the like. The sound information collected by the terminal device 10 is information on audible sounds and inaudible sounds that are circulated in stores, for example. The communication history of near field communication includes, for example, Bluetooth (registered trademark), the time when infrared communication or the like was performed, and the like.

  Web history information, program execution history information, operation history information, charging history information, posture change information, and environment information are generated by the processing unit 12.

  The GPS positioning unit 16 functions as a position information acquisition unit that acquires position information. The GPS positioning unit 16 specifies the position of the device itself, generates position information, and outputs the position information to the processing unit 12. At this time, the GPS positioning unit 16 receives a GPS signal including the position and time of the GPS satellite from a plurality of GPS satellites. The GPS positioning unit 16 calculates the distance between the plurality of GPS satellites and the terminal device 10, and specifies the position of the own device by triangulation calculation. The specified position and time are supplied from the GPS positioning unit 16 to the processing unit 12 as position information.

  The GPS positioning unit 16 operates in at least two states, a sleep state and a normal operation state. Among these, the sleep state is a state in which standby is performed without performing positioning, and is a state in which power consumption is less than that in the normal operation state. The normal operation state is a state in which positioning is performed, and is a state in which power consumption is higher than that in the sleep state. The GPS positioning unit 16 changes the state according to the activation request from the processing unit 12. Specifically, the GPS positioning unit 16 makes a transition from the sleep state to the normal operation state using the activation request from the processing unit 12 as a trigger. In addition, the GPS positioning unit 16 makes a transition from the normal operation state to the sleep state by using the end of the positioning calculation as a trigger. Here, the activation request is a request that the processing unit 12 outputs to the GPS positioning unit 16, and is a request for execution of processing for specifying the position of the own device and generating position information.

  In other words, the GPS positioning unit 16 is in a sleep state during a period of waiting for an input of an activation request output from the processing unit 12. The sleep state is a state of operating with power saving and is canceled by a start request. The GPS positioning unit 16 is activated in response to an activation request input from the processing unit 12. As a result, the GPS positioning unit 16 switches from the sleep state to the normal operation state. The activation request is a command for acquiring position information of the own device. When the GPS positioning unit 16 acquires position information in response to the activation request and outputs it to the processing unit 12, the GPS positioning unit 16 enters a sleep state after a predetermined time.

Note that the position information acquisition unit that acquires the position information may acquire the position information by another method.
The location information acquisition unit may acquire location information by a cell ID (mobile phone base station) method. In the cell ID method, when the terminal device 10 is a mobile phone terminal, the current location of the terminal device 10 is calculated based on radio wave information of three or more mobile phone base stations by applying a communication function as a mobile phone terminal. .
The position information acquisition unit may acquire position information by a Wi-Fi method. In the Wi-Fi scheme, radio waves transmitted from wireless LAN access points around the terminal device 10 are detected, and the location information of the terminal device 10 is acquired from the access point or a predetermined server based on the location information of the access point. .
Furthermore, the position information acquisition unit may acquire position information by a network positioning method. In the network positioning method, position information is acquired by positioning using the cell ID method and the Wi-Fi method.
As described above, the position information acquisition unit is activated from the sleep state in response to the activation request from the processing unit 12 even in a configuration using not only the GPS positioning method but also the cell ID method or the Wi-Fi method. Location information can be acquired.
In the present embodiment, the terminal device 10 gives priority to the positioning method by the GPS positioning unit 16 over the Wi-Fi method and the cell ID method as the position information acquisition method. The terminal device 10 switches to the positioning by the cell ID method or the Wi-Fi method instead of the positioning by the GPS positioning unit 16 in a situation where the GPS positioning unit 16 cannot perform positioning, for example, the terminal device 10 is indoors.

  The processing unit 12 is a software function unit that functions when a processor such as a CPU (Central Processing Unit) executes a program stored in a memory. Some or all of these functional units may be hardware functional units such as LSI (Large Scale Integration) and ASIC (Application Specific Integrated Circuit).

  The processing unit 12 includes application processing units 120A, 120B, and 120C (hereinafter simply referred to as “application processing unit 120” when collectively referred to). The application processing units 120A, 120B, and 120C are software function units that function when the CPU executes the application programs A, B, and C. In the present embodiment, each of the plurality of application processing units 120A, 120B, and 120C executes arbitrary application processing. In this embodiment, three application programs A, B, and C are executed, but any application program that executes two or more application programs at the same time may be used.

  The terminal device 10 may perform an operation for application authentication when the application programs A, B, and C are activated. In this case, when the application program is activated, the terminal device 10 transmits an application ID predetermined for each application program to the authentication server 40. More specifically, the terminal device 10 transmits an application ID indicating the application program A to the authentication server 40 when the application program A is activated. The terminal device 10 receives an authentication result indicating whether application authentication is permitted from the authentication server 40. The terminal device 10 permits the application program to be activated only when the authentication result is “permitted”.

The processing unit 12 can execute a plurality of applications A, B, and C at the same time. The processing unit 12 executes an application having a low priority among the plurality of applications A, B, and C in the background. Note that each of the applications A, B, and C may be set to output an activation request for each unique period or each unique timing. A unique predetermined period or a unique timing may be set for each of the applications A, B, and C.
The unique predetermined period may be 1 minute, 10 minutes, 1 hour or the like based on the type of application, for example. Further, the unique predetermined period may be changed so as to be a period specified by the user by accepting a user operation. Further, the unique predetermined period may be automatically changed based on the past positioning history. For example, when setting the next predetermined period, the processing unit 12 calculates the moving distance within the previous predetermined period from the two pieces of position information measured before and after the start of the previous predetermined period. If there is a movement of the own device in a predetermined period or the movement distance is long, the next predetermined period may be changed short.
The unique timing includes a timing at which the cell ID corresponding to the base station with which the device itself communicates and the access point ID of the WiFi access point with which the device can communicate change. The processing unit 12 can determine the arrival of the output timing of the activation request triggered by the change of the cell ID or access point ID. Further, the unique timing may be a timing at which it is estimated that the own device has moved a predetermined distance by detecting the movement of the own device such as an acceleration sensor described later. As will be described later, the predetermined distance may be reset or changed in response to the own device entering a predetermined area. Further, the predetermined distance may be changed so as to be a distance designated by the user upon receiving a user operation.

In the configuration of FIG. 2, each of the application programs A, B, and C has a position information library attached thereto. That is, the application program A is attached with the position information library A. The application program B is attached with a position information library B, and the application program C is attached with a position information library C. In the following description, these position information libraries A, B, and C are collectively referred to as a position information library.
This position information library outputs an activation request to the GPS positioning unit 16. Further, the position information library acquires the position information generated by the GPS positioning unit 16 in response to the activation request, and outputs the acquired position information to the application program. Thereby, the application program can use the position information generated by the GPS positioning unit 16.
The position information library is software executed by the CPU of the terminal device 10. That is, in the terminal device 10, the CPU executes the position information library. Thereby, the terminal device 10 constitutes position information acquisition control units 122A, 122B, and 122C (hereinafter, simply referred to as “position information acquisition control unit 122” when collectively referred to) as software function units. That is, the processing unit 12 has the position information acquisition control unit 122 for each application.
Each position information library for realizing the position information acquisition control unit 122 has its own positioning timing and position information transmission timing. Each location information library attached to a plurality of applications differs in the type and frequency of use of the attached application, the date and time of download, the software version, or the like. Therefore, preferable timings are set for the positioning timing and the transmission timing of each position information library.
As will be described later, when the own device is changed by switching between the normal mode and the power saving mode, and the position information library as the master is changed according to the changed operation mode, the positioning timing and transmission timing of the own device are changed. To change.

  Here, each of the application programs A, B, and C has a position information library attached thereto, but it is not always necessary that all of these position information libraries output an activation request to the GPS positioning unit 16. . That is, the processing unit 12 may include one position information acquisition control unit 122 that acquires position information and makes the position information available to the application processing unit 120 among the plurality of position information acquisition control units 122. That's fine. The “one position information acquisition control unit 122” is realized by a position information library which is a master described later. “One position information acquisition control unit 122” may be attached as one position information library corresponding to a plurality of applications, as will be described later with reference to FIG.

The application processing unit 120 uses position information that is acquired by the GPS positioning unit 16 by one position information acquisition control unit 122.
“Use location information” includes using location information within the terminal device 10. For example, the application processing unit 120 can display the position of its own device on the map based on the position information acquired by the GPS positioning unit 16 by using the position information.
“Using position information” includes using information based on position information acquired by the GPS positioning unit 16. Information based on position information is new information obtained by using position information. The information based on the position information may be information obtained by processing based on the position information in the terminal device 10, or information obtained by processing based on the position information in the application server 50. It may be. For example, the application processing unit 120 may extract advertisement information of a store close to the position of the own device and display the advertisement information as a push advertisement. The application processing unit 120 may receive the advertisement information extracted based on the position information by the application server 50 and display the advertisement information as a push advertisement.

The application processing unit 120 makes the position information acquired by one position information acquisition control unit 122 available. “Making location information available” includes causing a device other than the terminal device 10 to acquire the position information and enabling a device other than the terminal device 10 to process the position information.
For this purpose, the application processing unit 120 permits the use of the position information acquired by the GPS positioning unit 16. At this time, the application processing unit 120 inquires of the user whether to permit transmission of the position information. When the user permits transmission of the position information, the application processing unit 120 generates permission information that permits the use of the position information. The application processing unit 120 transmits the generated permission information to the location information server 30. After receiving the permission information transmitted from the terminal device 10, the location information server 30 can accumulate the position information transmitted from the terminal device 10 and transmit it to the application server 50 or the like thereafter. Accordingly, the application processing unit 120 can cause the application server 50 to analyze the position of the terminal device 10 by using the position information.

  Furthermore, the application processing unit 120 is installed in the terminal device 10 in advance. The application processing unit 120 may be installed in the terminal device 10 as the position information library is supplied to the terminal device 10. Specifically, an application program with a location information library is downloaded at the same time and installed in the terminal device 10. Accordingly, the terminal device 10 can include the application processing unit 120 and the position information acquisition control unit 122.

The location information library is downloaded according to the user's permission. When the application program is activated, the application processing unit 120 displays a screen for inquiring whether transmission of position information of the own device is permitted. When transmission of location information is permitted based on a user operation, the application processing unit 120 transmits a download request for the location information library.
The location information server 30 transmits a location information library to the terminal device 10 in response to receiving the download request. As a result, the terminal device 10 starts downloading the position information library. When the download is completed, the processing unit 12 attaches the position information library to each application program.

The processing unit 12 may attach the downloaded position information library to another application. The processing unit 12 duplicates the downloaded location information library and incorporates it into an application not provided with the location information library. As a result, the processing unit 12 can attach the position information library to an application that does not have the position information library.
The processing unit 12 may update to the latest version of the position information library instead of the old version of the position information library already incorporated in the application. Accordingly, the processing unit 12 can update the position information library of the application to the latest one.

  The position information acquisition control unit 122 makes an activation request to the GPS positioning unit 16. One position information acquisition control unit 122 among the plurality of position information acquisition control units 122A, 122B, and 122C attached to the plurality of application processing units 120A, 120B, and 120C makes an activation request to the GPS positioning unit 16. One position information acquisition control unit 122 that makes an activation request among the plurality of position information acquisition control units 122 is specified in advance. That is, it is specified which application program among the plurality of application programs A, B, and C outputs the activation request from the position information acquisition control unit 122 to the GPS positioning unit 16.

Among the plurality of position information acquisition control units 122, the position information acquisition control unit 122 that has output the activation request is supplied with position information from the GPS positioning unit 16. The position information acquisition control unit 122 notifies the other position information acquisition control unit 122 that the position information is supplied from the GPS positioning unit 16. The other position information acquisition control unit 122 requests position information from the position information acquisition control unit 122 that has output the activation request in response to the notification indicating that the position information has been supplied. The position information acquisition control unit 122 that has output the activation request outputs position information to the other position information acquisition control unit 122 in response to a request from the other position information acquisition control unit 122.
The processing unit 12 receives a user operation, and based on the received user operation, the position information acquisition control unit 122 attached to the application that permits the provision of the position information, or the provision of the position information is prohibited. The position information acquisition control unit 122 attached to the application may be set. When the position information acquisition control unit 122 that has output the activation request receives the request from the other position information acquisition control unit 122, the other position information acquisition control unit 122 attached to the application that is permitted to provide the position information in advance. Output location information only. In addition, the position information acquisition control unit 122 that has output the activation request supplies new position information from the GPS positioning unit 16 when there is another position information acquisition control unit 122 attached to an application for which provision of position information is prohibited. Even if this is done, no notification is sent to the other location information acquisition control unit 122 attached to the application for which provision of location information is prohibited.
Here, the location information acquisition control unit 122 that has output the activation request is the location information acquisition control unit 122 attached to the application specified in advance. The other position information acquisition control unit 122 is a position information acquisition control unit 122 attached to an application other than the application specified in advance. That is, the position information acquisition control unit 122 attached to the application specified in advance outputs the position information to the position information acquisition control unit 122 attached to another application. As a result, the position information acquisition control unit 122 attached to another application can acquire the position information generated by the GPS positioning unit 16 without making an activation request to the GPS positioning unit 16.

Here, the position information acquisition control unit 122 attached to the application specified in advance is also referred to as a position information acquisition control unit 122 having the authority of the master. Further, the position information acquisition control unit 122 attached to an application other than the application specified in advance is also referred to as a position information acquisition control unit 122 that does not have master authority or a slave position information acquisition control unit 122.
In other words, one location information acquisition control unit 122 that outputs an activation request has master authority over the other location information acquisition control unit 122. The other position information acquisition control unit 122 functions as a slave with respect to the master position information acquisition control unit 122. The other position information acquisition control unit 122 does not transmit an activation request to the GPS positioning unit 16. When receiving the notification from the master position information acquisition control unit 122, the other position information acquisition control unit 122 requests the position information from the master position information acquisition control unit 122 and acquires the position information.

  The storage unit 18 is a recording medium that stores various types of information. The storage unit 18 accumulates the position information acquired by the position information acquisition control unit 122. The storage unit 18 stores position information in time series. When performing application authentication, the storage unit 18 may store an application ID of an application program permitted to be activated in association with position information.

  Further, the storage unit 18 stores a position information library as a position acquisition control program for operating the position information acquisition control unit 122. The position acquisition control program is a program that can be read by a computer.

The position information acquisition control unit 122 reads the position information stored in the storage unit 18 and outputs the position information to the communication unit 14 when transmitting the position information to the position information server 30. Accordingly, the position information acquisition control unit 122 causes the communication unit 14 to transmit the position information read from the storage unit 18 to the position information server 30.
Note that the position information acquisition control unit 122 may transmit the position information directly to the application server 50 without using the position information server 30.

The location information acquisition control unit 122 causes the location information server 30 to transmit location information when a predetermined condition is met. The predetermined condition is a transmission timing determined in advance in the terminal device 10.
The predetermined condition may be a predetermined period transmitted from the location information server 30. Thereby, the terminal device 10 can transmit position information to the position information server 30 at a frequency requested by the position information server 30.
The predetermined condition may be a timing set by an application. Thereby, the terminal device 10 can transmit position information to the position information server 30 at a frequency requested by the application.
The predetermined condition may be a predetermined period transmitted from the application server 50 when the positional information is transmitted directly to the application server 50 without using the positional information server 30. Thereby, the terminal device 10 can transmit position information to the application server 50 at a frequency requested by the application server 50.

  When the position information acquisition control unit 122 transmits the position information to the position information server 30, all or all of the web history information, the program execution history information, the operation history information, the charging history information, the posture change information, and the environment information are included together with the position information. A part may be transmitted.

  Furthermore, the position information acquisition control unit 122 may store the transmission completion or the transmission failure of the position information as a transmission history every time the position information is read from the storage unit 18 and communicated by the communication unit 14. For example, if the position information acquisition control unit 122 cannot transmit the position information due to the influence of radio waves around the device itself, the position information acquisition control unit 122 stops the transmission of the position information and displays a transmission history indicating that transmission is impossible in association with the position information. The data is stored in the storage unit 18. The position information acquisition control unit 122 refers to the transmission history at the transmission timing, reads out the position information acquired by the GPS positioning unit 16 after the previous transmission timing and the position information that cannot be transmitted from the storage unit 18, and communicates with the communication unit 14. To communicate. Thereby, the position information acquisition control unit 122 can transmit the position information without omission even when a situation where the position information cannot be transmitted occurs.

  FIG. 3 shows another configuration example of the terminal device 10. The terminal device 10 is not limited to the configuration shown in FIG. 2, and may be configured as shown in FIG. The terminal device 10 in FIG. 3 has one position information acquisition control unit 122 for a plurality of application processing units 120A, 120B, and 120C. The position information acquisition control unit 122 is implemented as one position information library corresponding to a plurality of applications.

FIG. 4 shows still another configuration example of the terminal device 10. In the terminal device 10, the position information acquisition unit 160 includes an acceleration sensor 161 in addition to the GPS positioning unit 16 described above. The acceleration sensor 161 changes its physical quantity in accordance with a change in acceleration applied to the terminal device 10 that is its own device. The acceleration sensor 161 may be a semiconductor capacitance sensor.
The terminal device 10 may include a gravity sensor, a gyro sensor, or a geomagnetic sensor in order to detect the behavior of the device itself. In the present embodiment, it is described that only the acceleration sensor 161 is provided. However, the gravity sensor, the gyro sensor, or the geomagnetic sensor may be provided together with the acceleration sensor 161 or instead of the acceleration sensor 161.

  The acceleration detected by the acceleration sensor 161 corresponds to the behavior of the terminal device 10. The position information acquisition unit 160 detects the movement of the own device based on the behavior detected by the acceleration sensor 161. The position information acquisition unit 160 updates the movement amount in response to detecting the movement of the own device. Unlike the actual movement amount of the terminal device 10, this movement amount is a movement amount estimated from the behavior of the terminal device 10. This movement amount is output from the position information acquisition unit 160 to the processing unit 12. Thereby, the processing unit 12 can accumulate in the storage unit 18 the position information of the own device that changes according to the movement amount.

  Note that the position information acquisition unit 160 may detect that the device itself has moved based on a change in physical quantity in the acceleration sensor 161. The position information acquisition unit 160 can cause the position information acquisition control unit 122 to determine the positioning timing in response to detecting that the own apparatus has moved. For example, the position information acquisition control unit 122 can determine that it is the positioning timing when the own apparatus is in a moving state. The position information acquisition control unit 122 can determine that it is the positioning timing when the movement distance per unit time or the movement distance from the predetermined position exceeds a predetermined distance (for example, 100 meters). .

  Further, the position information acquisition control unit 122 may determine the positioning timing based on an identifier of a communication area in which the communication unit 14 can communicate. Examples of the identifier of the communication area include a cell ID of a base station or an access point ID in a Wi-Fi network. The position information acquisition control unit 122 can determine that the timing at which it is determined that the identifier of the communication area detected by the communication unit 14 has changed is the positioning timing.

  Next, the operation of the terminal device 10 will be described. FIG. 5 is a flowchart for determining whether to perform master determination processing for determining the position information acquisition control unit 122 having the authority of the master by the terminal device 10 configured as shown in FIG. FIG. 5 is a flowchart showing a processing procedure of master determination processing.

  First, in step S100 of FIG. 5, the terminal device 10 determines whether or not a plurality of application programs are simultaneously activated by the processing unit 12. If a plurality of application programs are activated, the process proceeds to step S102. When only one application program is activated, the terminal device 10 repeats this determination.

  In step S102, the processing unit 12 performs the master determination process of FIG. This master determination process is described as being performed by the processing unit 12 of each position information acquisition control unit 122. This master determination process is merely an example, and it goes without saying that the position information library as a master may be determined by other processes.

First, in step S200 of FIG. 6, the processing unit 12 determines whether or not the current operation mode of the own apparatus is the power saving mode. This power saving mode is an operation mode in which the positioning interval or number of times by the GPS positioning unit 16 or the interval or number of times of transmission of position information by the communication unit 14 is reduced in order to suppress power consumption of the own device.
At this time, the processing unit 12 refers to the remaining battery level in the own device. The processing unit 12 determines that the power saving mode is set when the remaining battery level is equal to or less than a predetermined value. If so, the process proceeds to step S202; otherwise, the process proceeds to step S204. Note that the processing unit 12 may detect that the power saving mode is set by a user operation.

In the next step S202, the processing unit 12 determines the position information acquisition control unit 122 attached to the application corresponding to the power saving mode as the position information acquisition control unit 122 having the authority of the master. At this time, the processing unit 12 refers to the attribute information of the application stored in advance in the storage unit 18 and selects the position information acquisition control unit 122 attached to the application corresponding to the power saving mode. The application corresponding to the power saving mode is an application that decreases the positioning interval or the number of times, or the position information transmission interval or the number of times.
In addition, the processing unit 12 downloads, for example, an application from the position information server 30 and data of a priority list for shifting the application to the power saving mode, and refers to the list to acquire position information acquisition control having the authority of the master. The part 122 may be selected. At this time, the processing unit 12 identifies the currently activated application and determines whether or not a plurality of applications are activated. When a plurality of applications are activated, the processing unit 12 refers to the list stored in the storage unit 18 and compares the priorities of the activated applications. As a result of the comparison, the processing unit 12 selects the position information acquisition control unit 122 attached to the application with the highest priority as the position information acquisition control unit 122 having the authority of the master. Thereby, the frequency of positioning and transmission of position information can be suppressed in the power saving mode.
Further, in the power saving mode, the processing unit 12 does not have the position information acquisition control unit 122 attached to the application, but a position information library dedicated to the power saving mode that operates independently of the application and has a master authority. The information acquisition control unit 122 may be selected. Thereby, the battery consumption of the terminal device 10 can be suppressed without depending on the running application, because the application has shifted to the power saving mode. The position information acquisition control unit 122 corresponding to the position information library independent of the application may be implemented as one position information library corresponding to a plurality of applications, for example, as shown in FIG. .
Furthermore, when selecting the location information acquisition control unit 122 attached to the application corresponding to the power saving mode, the processing unit 12 gives the master the authority to the location information acquisition control unit 122 attached to the old version application. The position information acquisition control unit 122 may be determined. Further, the processing unit 12 may determine the position information acquisition control unit 122 attached to an application with less information to be acquired as the position information acquisition control unit 122 having the authority of the master. The information acquired by the application includes position information. As described above, this position information includes web history information, program execution history information, operation history information, charging history information, posture change information, and environment information. The processing unit 12 may select the position information acquisition control unit 122 having the authority of the master by determining the amount of any information included in the position information or the amount of all information included in the position information. .
In step S202, the processing unit 12 determines a position information acquisition control unit 122 other than the position information acquisition control unit 122 having the authority of the master as the slave position information acquisition control unit 122.

In step S204, the processing unit 12 detects the position information acquisition control unit 122 that matches a predetermined master determination condition. As the predetermined master determination condition, a condition for setting the position information library as the position information acquisition control unit 122 having the authority of the master is set in advance. The predetermined master determination condition may be the position information acquisition control unit 122 attached to an application that frequently makes a start request to the GPS positioning unit 16 among a plurality of applications. In this case, the processing unit 12 refers to data including a history of application program activation times. The processing unit 12 detects an application having the largest number of activations. Thus, the processing unit 12 detects the position information acquisition control unit 122 attached to the application with the largest number of activations as the position information acquisition control unit 122 of the master candidate.
The predetermined master determination condition may be the position information acquisition control unit 122 attached to the application activated first among the plurality of applications. In this case, the processing unit 12 refers to data including a history of application activation times. The processing unit 12 detects an application having the oldest activation time among currently activated applications. The position information acquisition control unit 122 attached to the application with the oldest start time is detected as the master candidate position information acquisition control unit 122.
The predetermined master determination condition may be a position information library having the latest version among a plurality of position information libraries. In this case, the processing unit 12 refers to the version information of each position information library attached to a plurality of applications. The processing unit 12 detects the position information library of the latest version information from the version information of the position information library. The processing unit 12 detects the position information acquisition control unit 122 corresponding to the position information library of the latest version information as the position information acquisition control unit 122 of the master candidate.

Note that the predetermined master determination conditions may include other conditions.
Another master determination condition may be to select a position information library attached to an application that is permitted to measure or transmit position information based on a user operation. For example, an application that uses location information or an application that makes location information available is installed in the terminal device 10. When these applications are installed or when these applications are activated, the processing unit 12 causes the display of the terminal device 10 to display a message that permits positioning or transmission of position information under the control of the applications. When positioning or transmission of position information is permitted by accepting a user operation, the processing unit 12 registers in the storage unit 18 that the application is permitted to position or transmit position information. Thereafter, when the processing unit 12 selects a location information library having the authority of the master, whether or not there is an application permitted to measure or transmit the location information with reference to the information registered in the storage unit 18. Determine. When there is an application for which positioning or transmission of position information is permitted, the processing unit 12 can select a position information library attached to the application as a position information library as a master.
The processing unit 12 may detect, as the master candidate position information acquisition control unit 122, the position information acquisition control unit 122 attached to an application having the oldest installation date and time that has a low possibility of being deleted.
In addition, the processing unit 12 selects the position information acquisition control unit 122 attached to the application having the most types or items of position information to be acquired by the GPS positioning unit 16 as the position information acquisition control unit 122 having the authority of the master. Also good. As described above, the position information acquired by the application includes web history information, program execution history information, operation history information, charging history information, posture change information, and environment information. The processing unit 12 may determine the amount of any information included in the position information, or the amount of all information included in the position information, and serve as the master candidate position information acquisition control unit 122.
Further, the processing unit 12 may detect the position information acquisition control unit 122 attached to the application having the highest frequency (positioning frequency) to be measured by the GPS positioning unit 16 as the position information acquisition control unit 122 of the master candidate.

  In step S206, the processing unit 12 determines the position information acquisition control unit 122 corresponding to the predetermined master determination condition detected in step S204 as the position information acquisition control unit 122 having the authority of the master. The processing unit 12 determines the position information acquisition control unit 122 other than the position information acquisition control unit 122 having the authority of the master as the position information acquisition control unit 122 having the authority of the slave. When a plurality of master candidate position information acquisition control units 122 are detected, the processing unit 12 determines that the position information acquisition control unit 122 that has a large number that matches a predetermined master determination condition The information acquisition control unit 122 may determine the information.

In this embodiment, the location information acquisition controller 122 may be determined by the location information server 30 having the authority of the master. The location information server 30 receives from the terminal device 10 a list that defines information about the running application and permission information that the user has permitted to use the location information. The location information server 30 can determine, with reference to the received list, the location information library that is permitted to use the location information and that belongs to the active application among the active applications. The position information server 30 notifies the terminal device 10 of the application to which the determined master position information library is attached. Thereby, the terminal device 10 can set the position information library attached to the application determined by the position information server 30 as a master.
Note that the location information server 30 allows the information on the running application and the user to use the location information from the terminal device 10 periodically, at a fixed date and time, or when a change occurs in the previously transmitted list. A list defining permission information may be received. As a result, the location information server 30 can notify the terminal device 10 of the next master without delay even when there is a change in the permission information that the application or the user that has been permitted to use the location information changes. .

  In addition, the location information server 30 is attached with a master location information library based on a list that defines the information of the activated application received from the terminal device 10 and permission information that the user has permitted to use the location information. A list may be created that defines the ranking of the applications that are running. As a result, when the application to which the master location information library is attached is deleted, the terminal device 10 can determine the location information library attached to the next rank application as the master.

  The position information acquisition control unit 122 having the authority of the slave has a unique positioning timing, and even if the position information acquisition control unit 122 that acquired the authority of the master at the unique timing requests the position information. Good. Accordingly, the position information acquisition control unit 122 having the authority of the slave can supply the position information to the application to which the position information acquisition control unit 122 is attached at a timing desirable for the application.

  As described above, the processing unit 12 can determine any one of the plurality of position information acquisition control units 122 as the position information acquisition control unit 122 having the authority of the master.

  FIG. 7 is a flowchart illustrating a processing procedure for causing the terminal device 10 to acquire position information by the master position information acquisition control unit 122 and transmitting the acquired position information to the position information server 30.

  First, in step S300, the master position information acquisition control unit 122 determines whether or not the positioning timing has come. The positioning timing is a timing for acquiring the position information of the own device. The positioning timing is a time interval set in advance in the own apparatus. The positioning timing may be a time interval specified by the position information server 30.

  In the next step S <b> 302, the master position information acquisition control unit 122 outputs an activation request to the GPS positioning unit 16. Thereby, the GPS positioning part 16 receives a GPS signal, performs a triangulation calculation, and pinpoints the position of an own apparatus. The GPS positioning unit 16 acquires the specified position as position information. The position information acquired by the GPS positioning unit 16 is supplied to the position information acquisition control unit 122 having the authority of the master. The position information acquisition control unit 122 having the authority of the master accumulates the supplied position information in the storage unit 18 together with the positioning time.

  In the next step S304, the position information acquisition control unit 122 having the authority of the master notifies the position information acquisition control unit 122 having the authority of the slave that the position information has been acquired in step S302.

  In the next step S306, the position information acquisition control unit 122 having the authority of the master determines whether or not the request is received from the position information acquisition control unit 122 having the authority of the slave. When the request is received (step S306: YES), the position information acquisition control unit 122 having the authority of the master stores the position information accumulated in step S302 in the position information acquisition control unit 122 having the authority of the slave that transmitted the request. Is output (step S308). The position information acquisition control unit 122 having the authority of the master outputs the position information to the position information acquisition control unit 122 having the authority of all the slaves that output the request. After the notification in step S304, if there is no request from the position information acquisition control unit 122 having the authority of the slave and a predetermined time has elapsed, the process may be timed out and the process proceeds to step S310.

In step S <b> 310, the position information acquisition control unit 122 having the authority of the master determines whether it is the transmission timing of the position information to the position information server 30. The transmission timing of the position information is when a predetermined time has elapsed from the previous transmission timing. The predetermined time is a time determined in advance in the own apparatus. The predetermined time may be a time interval requested by the location information server 30.
When the transmission timing of the positional information is reached (step S310: YES), the positional information acquisition control unit 122 having the authority of the master reads the positional information that has not been transmitted to the positional information server 30 from the storage unit 18, and the positional information server 30 (step S312). If it is not the transmission timing, the position information acquisition control unit 122 having the authority of the master returns the process to step S300.

As described above, the terminal device 10 acquires a position information acquisition unit (GPS positioning unit 16) that acquires position information by starting in response to the start request, and one position information acquisition that makes a start request to the position information acquisition unit. A control unit (122) and a plurality of applications (application processing unit 120) corresponding to one position information acquisition control unit are included.
According to this terminal device 10, it has one position information acquisition control part 122 with respect to a some application. Thereby, the terminal device 10 can avoid outputting an activation request from each of the application processing units 120 to the GPS positioning unit 16. Therefore, according to the terminal device 10, the number of times of positioning by the GPS positioning unit 16 can be suppressed, and power consumption for acquiring position information can be suppressed.

  The GPS positioning unit 16 in the terminal device 10 is a module that specifies a position by performing a positioning calculation based on satellite radio waves. According to the terminal device 10, the power consumption of the GPS positioning unit 16 is high compared to the process of specifying the position by an acceleration sensor or the like, so that the number of positioning times by the GPS positioning unit 16 is suppressed and position information is acquired. Power consumption can be suppressed.

The terminal device 10 acquires position information, and a position information library that enables use of the acquired position information by an application is associated with each of a plurality of applications. In this terminal device 10, one of the position information libraries makes a start request to the position information acquisition unit as the position information acquisition control unit.
According to the terminal device 10, since one location information library issues a startup request to the location information acquisition unit, even if a location information library is attached to each of a plurality of applications, a startup request is output from each location information library. Can be avoided. Therefore, according to the terminal device 10, the number of times of positioning by the GPS positioning unit 16 can be suppressed, and power consumption for acquiring position information can be suppressed.
Further, according to the terminal device 10, even when a plurality of position information libraries are installed and the providers of the respective applications are different, the master can be determined in cooperation between the position information libraries. . Thereby, the terminal device 10 can set one position information library that outputs an activation request among a plurality of position information libraries. Further, when the position information library having the authority of the master acquires the position information, the terminal device 10 can output the position information to another position information library and share the position information among the plurality of position information libraries. it can.

  In the terminal device 10, a position information library attached to an application with low power consumption for acquiring position information among a plurality of applications can make an activation request to the position information acquisition unit. Thereby, according to the terminal device 10, while suppressing the frequency | count of positioning of the GPS positioning part 16, the electric power required for one positioning can be suppressed, and also power consumption can be suppressed.

  In the terminal device 10, a position information library attached to an application that is frequently used among a plurality of applications can make an activation request to the position information acquisition unit. Thereby, according to the terminal device 10, the position information library attached to the application with high use frequency of the user can output the start request with priority over the application with high frequency of operation in the background. Thereby, according to the terminal device 10, the frequency | count of starting the application which carries out power saving operation | movement in order to acquire position information can be suppressed. Thereby, according to the terminal device 10, while suppressing the frequency | count of positioning of the GPS positioning part 16, the electric power required for one positioning can be suppressed, and also power consumption can be suppressed.

  In the terminal device 10, a position information library attached to an application activated first among a plurality of applications can make an activation request to the position information acquisition unit. Thereby, according to the terminal device 10, it is possible to make an activation request only from the location information library immediately after the application program with the location information library attached is activated.

  The terminal device 10 can make an activation request to the position information acquisition unit with the position information library having the latest version among the plurality of position information libraries. Thereby, the terminal device 10 can make an activation request from the highly reliable position information library to the GPS positioning unit 16.

  In the terminal device 10, the position information acquisition control unit can be realized as one program corresponding to a plurality of applications. Thereby, according to the terminal device 10, even if it does not employ | adopt the structure attached as a positional information library with respect to each application, the frequency | count of positioning of the GPS positioning part 16 can be suppressed, and the power consumption for acquiring positional information is suppressed. it can.

  The terminal device 10 can use information based on position information by at least one of a plurality of applications. Thereby, according to the terminal device 10, even if the application does not directly use the position information, the position information can be acquired while suppressing power consumption.

  The terminal device 10 can permit at least one application of the plurality of applications to acquire the position information. According to this terminal device 10, even if it is a case where transmission of the position information of the own apparatus is simply permitted, power consumption for acquiring the position information can be suppressed.
