  The location information positioning unit 3 is a module having a location information positioning function of the terminal device 1, and specifically performs location information positioning processing using information on GPS, WiFi, and base stations. The positioning result by the position information positioning unit 3 is stored in the common position information positioning result DB 5 every time the positioning is performed.

  The common position information positioning control unit 4 is a module that outputs a position information positioning request to the position information positioning unit 3 at a constant frequency. Details of the frequency of position information positioning in the common position information positioning control unit 4 will be described later.

Moreover, you may store the log | history of the positioning result of the positional information measured in the past.

  The location information positioning request processing unit 6 receives a location information positioning request output from the application 2 (“application A”, “application B”, “application C”) installed in the terminal device 1, and receives the common location information positioning result. With reference to DB5, the process which outputs the latest positioning result in common position information positioning result DB5 to the application 2 is performed. Accordingly, since these applications can obtain position information from the common position information positioning result DB 5 without directly operating the GPS, it becomes possible to efficiently process position information positioning requests from a plurality of applications. .

FIG. 2 shows a basic processing flow when position information positioning is performed using the terminal device of the present invention.
First, the common position information positioning control unit 4 of the terminal device 1 determines whether or not position information positioning is necessary at the present time (step 10). Various methods can be considered for determining whether or not position information positioning is necessary, that is, for adjusting the position information positioning frequency. Details thereof will be described later.
If the common position information positioning control unit 4 determines that position information positioning is necessary, the position information positioning unit 3 executes the current position positioning process (step 20), and stores the result in the common position information positioning result DB 5 (Step 30).

  In the positioning information stored in the common position information positioning result DB 5, as shown in FIG. 3, for example, each information of positioning means such as ID number, positioning time, latitude, longitude, GPS or WiFi for each positioning result is included. included. In the common position information positioning result DB 5, all positioning results by the position information positioning unit 3 may be stored. Further, in order to save the storage medium, it may be mounted so as to store only the positioning information measured within a certain period. Further, it may be mounted so as to store only the latest positioning result.

Next, determination of the necessity of position information positioning in the common position information positioning control unit 4 (frequency of performing position information positioning) will be described. Various methods can be considered for the positioning frequency.
For example, the common position information positioning control unit 4 includes a positioning frequency adjustment unit 41 and measures the position information at regular time intervals (for example, every 3 minutes) determined by the positioning frequency adjustment unit 41. In this case, the difference between the latest position information positioning time and the current time is performed by comparison with a specified interval. Moreover, you may make it have the function which the user of the terminal device 1 can set freely about the conditions of the positioning time interval in the positioning frequency adjustment part 41. FIG.

Further, the positioning frequency adjustment unit 41 may automatically adjust the positioning frequency of the position information according to the frequency of the position information positioning request from the individual application 2. That is, the common position information positioning control unit 4 sets the time interval of position information positioning based on the frequency of position information positioning requests by the individual applications 2 (applications A, B, and C) installed in the terminal device 1. Configure as follows.
For example, the common position information positioning control unit 4 calculates an average position information positioning request frequency per unit time based on the number of position information positioning requests from each application 2 within a certain time. And when this frequency is lower than the pre-stored estimated value, the process in the location information positioning unit 3 is executed in response to the location information positioning request from each application 2, or common when the frequency is higher than the assumed value. Processing such as shortening the time interval determined by the position information positioning unit 4 is performed.

Further, the common location information positioning control unit 4 calculates the usage frequency of the terminal device 1 for each unit time, and the positioning frequency adjustment unit 41 adjusts the frequency of location information positioning for each unit time according to the usage frequency. May be.
For example, based on the usage history of the terminal device 1, a time zone frequently used by the user and a time zone with low usage frequency are defined, and the positioning frequency adjustment unit 41 performs position information positioning for each time zone. The time interval may be adjusted.

FIG. 4 shows another embodiment of the terminal device 1, in which a positioning necessity determination unit 42 is provided in the common position information positioning control unit 4, and the terminal device 1 is placed in the positioning necessity determination unit 42. Is detected and the positioning frequency of the position information is adjusted. Portions having the same configuration as that of the terminal device 1 in FIG.
In this example, a sensor unit 7 (acceleration sensor mounted on the terminal device 1) that provides information to the common position information positioning control unit 4 is installed, and information from the sensor unit 7 is sent to the common position information positioning control unit 4. It is input and used as information for determining the necessity of positioning information positioning in the positioning necessity determination unit 42. That is, based on the information obtained from the sensor unit (acceleration sensor) 7, it is possible to determine whether or not the terminal device 1 may have moved since the latest position information positioning time.

  For example, when the terminal device 1 is left on a desk or the like, the movement detected by the sensor unit (acceleration sensor) 7 becomes zero, so that it is possible to detect a situation where the terminal device 1 is not moving. Based on this information, it can be determined that the position information of the terminal device 1 need not be measured. When position information positioning is not performed, power consumption associated with the position information positioning process can be suppressed.

FIG. 5 shows a procedure of positioning frequency processing by the terminal device 1 shown in FIG.
The sensor unit (acceleration sensor) 7 detects the acceleration of the terminal device 1 (step 11).
It is determined whether or not the acceleration detected by the acceleration sensor is equal to or less than a preset threshold value (step 12).
If the detected acceleration is smaller than the threshold value, the position information positioning process is not performed, and the position information positioning process is executed in the common position information positioning control unit 4 only when the threshold value is exceeded (step 20).
When the position information positioning process is performed, the positioning process result is stored in the common position information positioning process result DB 5 each time (step 30).

  Further, instead of the acceleration sensor, the movement of the terminal device 1 is detected by a sensor that detects whether the terminal device 1 is charged or a proximity sensor that detects whether the user operating the device is nearby, The positioning necessity determination unit 42 may determine the frequency of positioning the position information based on these pieces of information.

Further, instead of the acceleration sensor, the sensor unit 7 may detect the communication status of the terminal device 1. In this case, it is possible to determine whether or not position information positioning is necessary based on the detected communication information.
For example, the sensor unit 7 is configured with a communication status detection device (WiFi information acquisition unit) that acquires WiFi information of a WiFi point, the position information of the connection point is registered in advance, and the WiFi information is referred to, so that it corresponds. When connected to a WiFi point, the position information positioning frequency is adjusted by using the registered position information as the measurement result without performing the position measurement by GPS or the like.

That is, by frequently registering the location information of the location where the WiFi connection is frequently made, if the location is connected by WiFi, the location information is recognized as the location of the registered location information, and it is determined that the location information need not be measured.
For example, if the WiFi connection is set at the user's home and the terminal device 1 is connected to the home WiFi when the user is at home, the terminal device 1 does not move while being connected. It is determined that it is not necessary to measure the position information, and the registered position information is used.
Moreover, you may make it grasp | ascertain the positional information on a connection point by detecting connection location ID from the connection condition at the time of WiFi connection.

FIG. 6 shows another embodiment of the terminal device 1. In the position information positioning frequency in the common position information positioning control unit 4, the position information positioning frequency is adjusted from information related to each application.
In this example, an application information DB 8 that stores information such as the accuracy of requesting position information in each of the applications A, B, and C and transmits / receives information to / from the position information positioning request processing unit 6 is installed. Among the apps installed in the terminal device 1, there is a possibility that a highly accurate position information is required regardless of the usage status, for example, a navigation app. In order to cope with such a situation, when the position information positioning request unit 6 receives a position information positioning request from each application, the application information DB 8 determines whether or not the application requires highly accurate position information. A process for referring to the information stored in is performed.

For example, when information indicating that the application A is an application that requires high-accuracy position information is stored in the application information DB 8, when the position information positioning request unit 6 receives a position information positioning request from the application A, Then, the position information positioning request processing unit 6 refers to the application information DB 8 to determine that high-accuracy position information is necessary, and a process of directly sending a position information positioning request from the application A to the position information positioning unit 3 is performed.
In the case of this example, for the applications B and C, when the position information positioning request unit 6 receives a position information positioning request from the applications B and C, the position information positioning request processing unit 6 refers to the application information DB 8. Therefore, it is determined that position information with high accuracy is not necessary, and processing for obtaining a position information positioning result from the common position information positioning result DB 5 is performed.

  According to each terminal device 1 described above, the position information positioning process in the position information positioning unit 3 is activated at a desired frequency by the common position information positioning control unit 4 including the positioning frequency adjusting unit 41 and the positioning necessity determining unit 42. The position information positioning result is stored in the common position information positioning result DB 5, and the position information positioning request processing unit 6 responds to the position information positioning request from individual applications (for example, apps A, B, C). Since position information is output for each application with reference to the positioning result DB 5, it is possible to efficiently process position information positioning requests from a plurality of applications and save power consumption of the terminal device 1. can do.
