Hereinafter, an example of a preferred embodiment for realizing the present invention will be described with reference to the drawings.
FIG. 1 shows a conceptual module configuration diagram of a configuration example of the present embodiment.
The module generally refers to a component such as software or hardware that can be logically separated. Therefore, the module in the present embodiment indicates not only a module in a program but also a module in a hardware configuration. Therefore, the present embodiment also serves as an explanation of a program, a system, and a method. However, for the sake of explanation, the words “store”, “store”, and equivalent terms are used. However, when the embodiment is a program, these terms are controlled to be stored in the storage device. I mean. In addition, the modules correspond almost one-to-one with the functions. However, in mounting, one module may be composed of one program, or a plurality of modules may be composed of one program. A plurality of programs may be used. The plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers in a distributed or parallel environment. Note that one module may include other modules. In the following, “connection” includes not only physical connection but also logical connection (data exchange, instruction, reference relationship between data, etc.).
Further, the system or apparatus includes a configuration in which a plurality of computers, hardware, devices, and the like are connected via a network and the like, and includes a case where the system or device is realized by a single computer, hardware, devices, and the like. The term “predetermined” is used in addition to a predetermined meaning, including the meaning according to the situation / state at that time or the situation / state until then.

  The portable information terminal device according to the present embodiment uses position information, and has a position information request module 110A, a position information request module 110B, a position processing module 120, and a positioning module 130 as shown in FIG. is doing.

  The positioning module 130 is connected to the position processing module 120. It is controlled by the position processing module 120 and measures the position of the portable information terminal device. For example, GPS. Further, the positioning module 130 may be capable of measuring the position by a plurality of methods. For example, in GPS, the AGPS system (Assisted Global Positioning System, a system that supports information on a mobile body by sending information from a fixed positioning point to a mobile body via a (wireless) network) and the Cell-ID system ( There are two types: one that obtains a base station ID and performs positioning. Of course, there may be three or more types. Which method is used depends on the control from the position processing module 120.

The position information request module 110 </ b> A and the position information request module 110 </ b> B are connected to the position processing module 120. In FIG. 1, two cases of location information request modules are illustrated, but three or more location information request modules may be used. Even if there is only one, it is sufficient if the position measurement request to the positioning module 130 is made a plurality of times. In the following description, two cases are mainly exemplified. Further, the position information request module 110A and the position information request module 110B can operate simultaneously. Here, the simultaneous operation includes a case where one is temporarily stopped and the other is operating.
The position information request module 110A or the position information request module 110B is an application program that uses position information. For example, the position information request module 110A or the position information request module 110B displays a map in the vicinity from the position of the portable information terminal device, or displays a weather forecast for the area. There are some that display nearby store information. The position information request module 110A or the position information request module 110B requests the position processing module 120 to measure the current position and acquires the position information. As the position information request module, for example, what is called a widget (widget, a program component constituting an application program or a combination thereof) is applicable. In the following description, this widget is included as an application program.

Moreover, you may make it include the positioning method designation | designated information which designates the positioning method as a request | requirement of a position measurement.
In addition to the request for the measurement result of the current position, the request for position measurement may be a request for notification if the position changes from now on, a request for notification of the position every predetermined time, or the like. .

  The position processing module 120 is connected to the position information request module 110A, the position information request module 110B, and the positioning module 130, and includes a request reception module 121, an answer module 122, a positioning control module 123, and a request date storage module 124. Yes.

The request reception module 121 receives a position measurement request for the positioning module 130 from the position information request module 110 </ b> A or the position information request module 110 </ b> B, and passes the request to the positioning control module 123. Since the request for position measurement is performed independently from the position information request module 110A or the position information request module 110B, a plurality of requests may be received within a predetermined period.
Further, the request receiving module 121 may receive positioning method designation information for designating a positioning method as a request.

  The response module 122 is controlled by the positioning control module 123, and returns the positioning result by the positioning module 130 corresponding to the request received by the request receiving module 121 to the location information request module 110A or the location information request module 110B that is the request source.

  When the request is received by the request receiving module 121, the positioning control module 123 controls the positioning module 130 to measure the position. When the second request is received by the request receiving module 121 after the first request is received by the request receiving module 121 and before the positioning result is obtained from the positioning module 130, the first request The response module 122 is controlled so as to return the positioning result for to the requester that made the second request as the positioning result for the second request. For example, the position information request module 110A makes a first request, and the position information request module 110B makes a second request before obtaining the positioning result from the positioning module 130 for the request. In this case, the positioning result for the first request is also returned for the second request.

In addition, the positioning control module 123 sets the positioning result for the first request as the positioning result for the second request when the positioning method designation information in the first request matches the second request. The answer module 122 may be controlled to return to the position information request module 110A or the position information request module 110B that is the second request source.
In addition, after the positioning control module 123 obtains the positioning result from the positioning module 130 and receives the second request by the request receiving module 121 within a predetermined period, the positioning result for the first request. As a positioning result for the second request, the answer module 122 may be controlled so as to return it to the position information request module 110A or the position information request module 110B that is the second request source.
Then, the positioning control module 123 stores the history related to the positioning process in the request date storage module 124. For example, as information to be stored, an identifier that can identify the request source position information request module 110A or the position information request module 110B received by the request reception module 121, positioning method designation information received by the request reception module 121 as a part of the request, The date and time of the request received by the request reception module 121 (may include year, minute, second, etc., the same applies hereinafter), the reception result reply date and time (date and time when the request was received by the position processing module 120), There are an answer date and time that is a date and time when the positioning result is returned to the request source via the answer module 122, position information that is a positioning result by the positioning module 130, and the like.

  The request date / time storage module 124 stores a history related to the positioning process under the control of the positioning control module 123. For example, the positioning history table 500 shown in the example of FIG. 5 is stored. The positioning history table 500 includes NO. A column 502, a request program column 504, a request positioning method column 506, a request date / time column 508, a reception result reply date / time column 510, an answer date / time column 512, and a position information column 514. The position information column 514 includes a latitude column 515. , A longitude column 516, a positioning accuracy column 517, and a last update date / time column 518.

NO. The column 502 stores a number that can identify a history from when a request is made until a positioning result is returned. For example, it is a number sequentially assigned to each stored history.
The request program column 504 stores an identifier that can identify the request source position information request module 110A or the position information request module 110B received by the request reception module 121.
The requested positioning method column 506 stores positioning method designation information received by the request receiving module 121 as a part of the request.

The request date / time column 508 stores the date / time of the request received by the request receiving module 121.
The reception result reply date and time column 510 stores the date and time when the position processing module 120 has returned the request from the position information request module 110A or the position information request module 110B.
The answer date / time column 512 stores the answer date / time that is the date / time when the positioning result is returned to the request source via the answer module 122.
The position information column 514 stores position information that is a positioning result by the positioning module 130. The position information is stored in the latitude column 515, the longitude column 516, the positioning accuracy column 517, and the last update date / time column 518 according to the type of the information.

FIG. 3 is a diagram illustrating a module configuration example when the present embodiment is embodied.
It has a map display program 310A, a weather forecast program 310B, a program execution control module 320, and a GPS 330.
The map display program 310A or the weather forecast program 310B corresponds to the position information request module 110A or the position information request module 110B shown in the example of FIG. 1, the program execution control module 320 corresponds to the position processing module 120, and the GPS 330 corresponds to the positioning module. It corresponds to 130. The program execution control module 320 includes a program execution environment module 321 and a program control module 322, and the program execution environment module 321 and the program control module 322 constitute a module in the position processing module 120. Yes. The program execution environment module 321 mainly corresponds to the request reception module 121, the response module 122, and the positioning control module 123, and the program control module 322 corresponds to the positioning control module 123 and the request date storage module 124.

  The map display program 310A and the weather forecast program 310B are connected to the program execution environment module 321 of the program execution control module 320. The map display program 310A and the weather forecast program 310B request the program execution environment module 321 to measure the current position independently (regardless of the other program).

  The program execution environment module 321 is connected to the map display program 310A, the weather forecast program 310B, and the program control module 322. Control is performed so that a plurality of application programs can operate, and the map display program 310A and the like and the program control module 322 are bridged. That is, it receives a request from the map display program 310A or the weather forecast program 310B and passes the request to the program control module 322. Then, the positioning result from the program control module 322 is received and returned to the requested map display program 310A or weather forecast program 310B.

The program control module 322 is connected to the program execution environment module 321 and the GPS 330. The hardware including the GPS 330 (display, key, etc. in addition to the GPS 330) is controlled, and the program execution environment module 321 is bridged with the GPS 330 and the like. That is, it receives an instruction from the program execution environment module 321 and passes the instruction to the GPS 330 or the like. Then, the processing result from the GPS 330 or the like is received and passed to the program execution environment module 321.
The GPS 330 is connected to the program control module 322 of the program execution control module 320. In accordance with the instruction from the program control module 322, positioning is performed according to the positioning method designation information, and the positioning result is returned to the program control module 322.

FIG. 4 is a flowchart showing an example of processing between modules shown in the example of FIG.
In step S <b> 400, the weather forecast program 310 </ b> B requests the program execution control module 320 for position measurement to update position information. Then, the positioning control module 123 generates a new line in the positioning history table 500 (at that time, stores a new number in the NO. Column 502), and makes the request received by the request receiving module 121. The identifier of the weather forecast program 310B is acquired and stored in the request program column 504 of the positioning history table 500. Then, the positioning method designation information received as a part of the request is stored in the requested positioning method column 506. Further, the request date / time is stored in the request date / time column 508.
In step S402, the program execution control module 320 makes a request received in step S400 to the GPS 330.
In step S <b> 404, the GPS 330 returns to the program execution control module 320 that the position measurement request for updating the position information has been received as a reception result. And GPS330 starts a positioning process according to the positioning method designation | designated information in a request | requirement.

In step S406, the GPS 330 performs position measurement processing.
In step S408, the program execution control module 320 returns to the weather forecast program 310B that it has received a position measurement request for updating position information as a reception result. Then, the positioning control module 123 stores the date and time when the reception result is returned in the reception result reply date and time column 510 of the positioning history table 500.
In step S410, the program execution control module 320 is in a situation where position measurement is being processed. For example, by using a status flag indicating the processing status of the GPS 330 (for example, “1” indicates processing, “0” indicates standby), the status flag is set during processing. This process may be performed immediately after step S404.

In step S412, the map display program 310A requests the program execution control module 320 to perform position measurement for updating position information. Then, the positioning control module 123 generates a new line in the positioning history table 500 (at that time, stores a new number in the NO. Column 502), and makes the request received by the request receiving module 121. The identifier of the map display program 310A is acquired and stored in the request program column 504 of the positioning history table 500. Then, the positioning method designation information received as a part of the request is stored in the requested positioning method column 506. Further, the request date / time is stored in the request date / time column 508.
Next, the positioning control module 123 confirms the status flag and confirms whether processing is in progress. If processing is in progress, the requested positioning method column 506 checks whether the positioning method designation information is the same as that already requested. If they are the same, no request is made to the GPS 330. If they are not the same, a process for waiting (queuing) is performed.
In step S414, the program execution control module 320 returns to the map display program 310A that the position measurement request for updating the position information has been received as a reception result. Then, the positioning control module 123 stores the date and time when the reception result is returned in the reception result reply date and time column 510 of the positioning history table 500.
In step S416, the GPS 330 completes the positioning process.

In step S418, the GPS 330 notifies the program execution control module 320 of the positioning result as a location information update event. Position information 450 is returned as a positioning result. The position information 450 includes latitude, longitude, positioning accuracy, last update date and time, and the like.
In step S420, the program execution control module 320 specifies the program that has returned the acceptance result in response to the position information update request. That is, an item that is not stored in the answer date / time column 512 in the positioning history table 500 is specified. The positioning control module 123 stores the position information 450 in the position information column 514 of the line corresponding to the program specified in the positioning history table 500. Then, the status flag is set to standby.
In step S422, the program execution control module 320 notifies the weather forecast program 310B of a location information update event.

In step S424, the weather forecast program 310B requests the program execution control module 320 to acquire position information.
In step S426, the program execution control module 320 returns position information 452 as a measurement result to the weather forecast program 310B. Then, the positioning control module 123 stores the date and time when the measurement result is returned in the answer date and time column 512.
In step S428, the weather forecast program 310B performs processing using the position information 452 (such as obtaining and displaying weather forecast data corresponding to the position from a server or the like).

In step S430, the program execution control module 320 notifies the map display program 310A of a location information update event.
In step S432, the map display program 310A requests the program execution control module 320 to acquire position information.
In step S434, the program execution control module 320 returns position information 454 as a measurement result to the map display program 310A. Then, the positioning control module 123 stores the date and time when the measurement result is returned in the answer date and time column 512.
In step S436, the map display program 310A performs processing using the position information 454 (such as displaying map information data at the position).

  If the positioning process fails, the GPS 330 notifies the program execution control module 320 of the positioning failure as a measurement result. In this case, the program execution control module 320 returns a positioning failure to the map display program 310A and the weather forecast program 310B as a measurement result.

  In the processing shown in the example of FIG. 4, the status flag is changed from processing to standby in step S <b> 420 immediately after receiving the position information update event from the GPS 330. It may be after receiving an information update event and after a predetermined period has elapsed. That is, if it is within the predetermined period, the owner of the portable information terminal device often does not move rapidly, and it is not necessary to cause the GPS 330 to perform the positioning process.

Further, the predetermined period may be changed according to the type of the program that requests the position information. For example, in the case of the weather forecast program 310B, since the weather forecast processing is performed in a relatively large area, the predetermined period may be set longer, but in the case of an application program that handles nearby store information The predetermined period should be set short (including 0). Therefore, the positioning control module 123 may perform processing as described below.
When the date and time when the positioning result is obtained from the GPS 330 (more specifically, the date and time when the status flag is changed from processing to standby) is stored, and then the request reception module 121 receives a position measurement request If the period from the date / time when the positioning result is obtained to the date / time when the request is received is within a predetermined period determined according to the type of the application program that is the request source, the previous positioning result is requested. Returning to the original application program, if it is not within the predetermined period, the GPS 330 is newly controlled to measure the position. The type of application program is obtained by, for example, preparing a table associated with the name of the application program in advance, extracting the name of the requesting application program, and searching the table. You may do it. In addition, a table in which the types of application programs are associated with the predetermined time may be prepared in advance.
