  The present invention relates to a positioning method determination device and a positioning method determination method for determining a positioning method of a mobile communication terminal.

  Conventionally, as a method for estimating the position of a mobile communication terminal, there is a method that uses the reception status of radio waves transmitted from a base station.

JP 2002-250765 A

  By the way, in recent years, various SNSs (Social Networking Services) have been popularized. Under such circumstances, when Internet search is performed, services related to real-time search that display writing of SNS or the like as a search result at the time of Internet search in real time (in seconds) are increasing.

  In such a real-time search service, the search result is displayed in consideration of time-related conditions such as displaying the latest posted post at the top of the search result. In addition, using the location information obtained by positioning the user's terminal, and displaying the post of the poster related to the area where the user exists as a search result, the search result in consideration of the conditions related to the location Some are displayed. In this way, by displaying the search result in consideration of temporal and place conditions, it is possible to display the search result that more matches the user's interest and interest.

  As described above, in a real-time search service that displays search results in consideration of locational conditions, it is necessary to obtain position information by positioning a user terminal. As a method of positioning a mobile communication terminal, there are base station positioning, GPS positioning, positioning using near field radio such as RFID, positioning using a geolocation API (Geolocation Application Program Interface), and the like. Of the various types of positioning described above, for example, the following two methods can be considered as positioning methods using the browser of the mobile communication terminal. First, as a first positioning method, there is a method of performing base station positioning described in Patent Document 1 described above. The first positioning method is a method in which a mobile communication terminal accesses a dedicated positioning server, and the positioning server performs positioning of the mobile communication terminal. There are a plurality of methods for performing positioning by base station positioning. In addition to the method described in Patent Document 1, for example, a base station used for communication (transmitting and receiving information with a mobile communication terminal by radio waves) is used. There is a method of specifying and notifying the user of location information based on information specifying the base station. As a second positioning method, there is a method using a geolocation API. The second positioning method is a method in which the mobile communication terminal performs positioning of the mobile communication terminal by executing a geolocation API using Javascript (registered trademark).

  The first positioning method (base station positioning method) has the following characteristics. That is, the first positioning method has an advantage that the positioning time is short and the battery consumption is small as compared with the second positioning method. On the other hand, the first positioning method requires that the mobile communication terminal accesses a dedicated positioning server, but has a communication path for accessing the dedicated positioning server depending on the communication type of the mobile communication terminal. In this case, there is a demerit that base station positioning cannot be performed. In other words, the first positioning method has a feature that the communication type capable of positioning is limited although the positioning time is short.

  Note that the communication type here includes not only a large group such as 3G or wireless LAN (Local Area Network) but also a type such as a specific communication service based on a contract between a user and a communication carrier (the following description) The same in). In addition, the communication path generally refers to a physical route for simply transmitting information (including both a wired route and a wireless route), but here, there is a physical route for transmitting information, and When the information transmission destination can be accessed via the route, the route for transmitting the information is defined as a communication path. Therefore, in this definition, for example, when there is a physical route to a certain server, but the server cannot be accessed by this route, the route to the server is not a communication path.

  The second positioning method (method using the geolocation API) has the following characteristics. That is, if the second positioning method is a mobile communication terminal that can be used by a browser that supports the geolocation API, regardless of the communication type, communication carrier, and communication terminal (cell phone, tablet computer, etc.) There is a merit that it is possible. On the other hand, the second positioning method has a demerit that there are variations in positioning time and positioning accuracy. That is, the second positioning method has a feature that positioning can be performed without depending on the communication type or the like, but positioning time and positioning accuracy vary.

  Here, when positioning is performed by the second positioning method, there are variations in positioning time and positioning accuracy, and it is difficult to say that the user can perform a comfortable search. Therefore, it is desirable to perform positioning of the mobile communication terminal by the first positioning method as much as possible. However, as described above, in the first positioning method, the base station positioning cannot be performed depending on the communication type of the mobile communication terminal at the time of the search, and when the base station positioning cannot be performed, the user can perform the base station positioning. After the failure, it is necessary to try positioning by the second positioning method again. As a result, the positioning time may become longer due to the necessity of changing the positioning method due to the positioning failure, even though the positioning is attempted by the first positioning method having a short positioning time. And there existed a possibility that the user's comfortable real-time search may not be implement | achieved by the positioning time of a mobile communication terminal becoming long.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a positioning method determination device and a positioning method determination method that can quickly perform positioning by determining an optimal positioning method for a mobile communication terminal. And

  A positioning method determining apparatus according to the present invention is a positioning method determining apparatus that determines a positioning method of a mobile communication terminal, and is specified by a communication path specifying unit that specifies a communication path of the mobile communication terminal and a communication path specifying unit. A positioning method determining unit that determines a positioning method according to a communication path of the mobile communication terminal, and a positioning method output unit that outputs information specifying the positioning method determined by the positioning method determining unit.

  In this positioning method determination apparatus, a positioning method is determined according to the specified communication path of the mobile communication terminal, and information for specifying the positioning method is output. As described above, depending on the communication path determined by the communication type of the mobile communication terminal, there is a positioning method in which positioning cannot be performed. Therefore, the communication path of the mobile communication terminal is specified in advance, and then positioning is performed according to the communication path. By determining the method, it is possible to determine an optimum positioning method for each mobile communication terminal.

  As described above, according to the present invention, positioning can be quickly performed by determining a positioning method optimal for the mobile communication terminal.

  In the positioning method determining apparatus according to the present invention, the communication path specifying means acquires the IP address of the mobile communication terminal, and whether or not the value of the IP address is a value within a predetermined band. It is preferable to specify the communication path of the mobile communication terminal.

  Since the bandwidth of the IP address used by the mobile communication terminal that uses each communication type is normally determined in advance, the IP address of the mobile communication terminal is acquired and whether or not the IP address is a value within a predetermined bandwidth. Can determine the communication path of the mobile communication terminal. By specifying the communication path by the IP address, the present invention can be reliably implemented.

  Further, the positioning method determining apparatus according to the present invention is configured so that the communication path specifying unit determines the communication path of the mobile communication terminal when the acquired IP address value of the mobile communication terminal is a value within a predetermined band. When it is specified that the communication path is capable of positioning by the first positioning method, and the acquired IP address value of the mobile communication terminal is a value outside a predetermined band, the communication path of the mobile communication terminal is Positioning by the first positioning method is impossible, and it is specified that the communication path is to perform positioning by the second positioning method, and the positioning method determining means uses the communication path specifying means so that the communication path becomes the first positioning. When it is specified that the communication path can be determined by the method, the communication path is determined as the first positioning method, and the communication path is determined by the second positioning method by the communication path specifying means. If it is determined that the positioning method is It is preferable to determine the position method.

  For example, the first positioning method has a short positioning time but cannot be measured depending on the communication path, and the second positioning method can perform positioning without depending on the communication path, but the positioning time varies. In this case, if the IP address is a value in the band and the communication path is capable of the first positioning method, the first positioning method is determined, and if the value is out of the band, the second positioning method is determined. Thus, if positioning is possible with the first positioning method with a short positioning time, positioning is performed with the first positioning method. If positioning is not possible with the first positioning method, positioning is performed with the second positioning method. Can be performed. That is, quick positioning is realized by determining an optimal positioning method for the mobile communication terminal.

  Further, the first positioning method in the positioning method determining apparatus according to the present invention is base station positioning in which positioning of the mobile communication terminal is performed by a preset server from information on radio waves transmitted / received to / from the base station. The second positioning method is preferably a positioning method other than the first positioning method.

  Base station positioning, which is a positioning method that is short in positioning time but cannot be determined depending on the communication path, is used as the first positioning method, so that base station positioning can be performed if the communication path is capable of base station positioning. It becomes possible and quick positioning is realized.

  The positioning method determination method according to the present invention is a positioning method determination method for performing positioning of a mobile communication terminal, the communication path specifying step for specifying the communication path of the mobile communication terminal, and the mobile communication specified in the communication path specifying step A positioning method determining step for determining a positioning method according to the communication path of the terminal; and a positioning method output step for outputting information for specifying the positioning method determined in the positioning method determining step. This positioning method determination method can achieve the same effects as the positioning method selection device described above.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a positioning method determination device and a positioning method determination method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  The positioning method determination apparatus according to the present invention specifies a communication path of a mobile communication terminal in a stage before executing positioning of the mobile communication terminal, and determines an optimal positioning method for the mobile communication terminal. Here, the communication path generally refers to a physical route that simply transmits information (including both a wired route and a wireless route), but here, there is a physical route that transmits information. In addition, when the information transmission destination can be accessed via the route, the route for transmitting the information is defined as a communication path. Therefore, in this definition, for example, when there is a physical route to a certain server, but the server cannot be accessed by this route, the route to the server is not a communication path.

  A mobile communication terminal is a device that can communicate via a wireless communication network. For example, the mobile communication terminal can perform mobile communication using a mobile communication network compliant with 3G or LTE (Long Term Evolution). In mobile communication, a user of a mobile communication terminal normally makes a contract with a communication carrier that provides the mobile communication network, and the mobile communication network is set to enable mobile communication for the mobile communication terminal. Is possible. The mobile communication terminal may be capable of performing wireless communication using a wireless LAN. In this case, communication may be performed by connecting to the core network of the mobile communication network via a wireless LAN.

  The mobile communication terminal includes a browser and can display information acquired (received) by the above communication on the browser.

  The positioning method determination according to the present invention is to determine an optimum positioning method for the mobile communication terminal using a browser of the mobile communication terminal. The browser here refers to a web browser used for using the World Wide Web. The browser designates a connection destination by a URL, communicates with a server using HTTP or the like, acquires information, and displays the information to the user. Therefore, determining the positioning method using a browser means that the mobile communication terminal and the server (a positioning method determining device and a base station positioning server described later) communicate with each other using HTTP or the like. This refers to determining the positioning method using.

  The determination of the positioning method using the browser described above may not include determination of the positioning method using an application that can be used only on a specific mobile communication terminal (smart phone or the like), for example. An application that can be used only on a specific mobile communication terminal is an application whose availability is determined by an OS (Operating System) such as a smartphone. In the OS, for example, it can be determined whether the mobile communication terminal is performing mobile communication or wireless LAN communication, and a positioning method can be determined based on this determination. Since such a positioning method determination method depends on the OS, the number of users that can be used is greatly limited. In this regard, the determination of the positioning method using the browser described above is to determine the positioning method using the browser provided for any mobile communication terminal, as compared to the determination of the positioning method using an application. More users can use it. From this, the present inventor studied the determination of a positioning method using a browser and came up with the present invention.

  The positioning method determination device transmits information (Web page) corresponding to the position of the mobile communication terminal to the mobile communication terminal. The mobile communication terminal transmits a request for the information to the positioning method determination device. This request includes a location information acquisition request for requesting location information indicating the location of the terminal itself. Using the request as a trigger, the positioning method is determined as described above, and the position of the mobile communication terminal acquired by the determined positioning method is used for transmitting the information.

  First, with reference to FIG. 1, the function of the positioning method determination apparatus 1 which concerns on this embodiment is demonstrated. FIG. 1 is a diagram showing a functional configuration of a positioning method determination apparatus 1 according to an embodiment of the present invention. The positioning method determination apparatus 1 according to the present embodiment executes an application based on a configuration for determining a positioning method, a configuration for outputting information for specifying a positioning method, and acquired position information (for example, latitude and longitude information). It has the composition. The positioning method determination device 1 determines a positioning method of a mobile communication terminal and executes an application based on the acquired position information in a real-time search service that displays search results in consideration of conditions related to a place. It is a server that is used as a server and is operated by, for example, a carrier that is a communication carrier. The positioning method determination device 1 communicates with the mobile communication terminal 30 and the base station positioning server 50 to realize the above-described functions.

  With reference to FIG.1 and FIG.2, the communication of the positioning method determination apparatus 1, the mobile communication terminal 30, and the base station positioning server 50 is demonstrated. FIG. 2 is a diagram for explaining a connection image of the mobile communication terminal to the external network. As shown in FIG. 2, the mobile communication terminal 30 communicates with a private IP address when located in the internal network (mobile communication network (core network)) of a communication carrier. When a proxy server provided in the mobile communication network accesses an external network (for example, the Internet), a global IP address is assigned and communication is performed. The positioning method determining device 1 and the base station positioning server 50 are servers located in an external network when viewed from the mobile communication terminal 30. The mobile communication terminal 30 communicates with the positioning method determination device 1 and the base station positioning server 50 located in the external network using 3G or LTE. It is also possible to communicate with the positioning method determination device 1 and the base station positioning server 50 located in the external network using a wireless LAN.

  The positioning method determination device 1 according to the present embodiment uses an IP address to identify the communication path of the mobile communication terminal 30. Then, after specifying the communication path, a positioning method optimum for the mobile communication terminal 30 is determined. Hereinafter, among the positioning methods, a base station positioning (first positioning method) and a geolocation positioning (second positioning method) will be described as examples. Therefore, the positioning method determination apparatus 1 according to the present embodiment determines the optimal positioning method for the mobile communication terminal 30 among the base station positioning (first positioning method) and the geolocation positioning (second positioning method). Is.

  Here, the base station positioning and geolocation positioning described above will be described. Base station positioning is a method in which the mobile communication terminal 30 accesses the base station positioning server 50 and the base station positioning server 50 performs positioning of the mobile communication terminal 30. Specifically, positioning of the mobile communication terminal 30 is performed by the base station positioning server 50 from information on radio waves transmitted to and received from the base station. There are multiple methods for positioning by base station positioning. For example, a base station used for communication (transmitting and receiving information with a mobile communication terminal by radio waves) is identified, and the base station is based on information for identifying the base station. There is a method in which position information (information indicating latitude and longitude where the base station is located) is used as the position information of the mobile communication terminal 30 (for example, “Hironori Matsuda, Toshinari Miyasaka, new functions of sp mode—position using base station data Information providing function, see NTT DOCOMO Technical Journal Vol.19 NO3, 2011 "). Here, information indicated by a base station used for communication corresponds to information on radio waves transmitted to and received from the base station. Alternatively, as shown in Patent Document 1, there is a method in which the base station positioning server 50 performs positioning based on the ID (cell ID) of the base station and the radio wave intensity from each base station.

  In the base station positioning, the position of the mobile communication terminal 30 is estimated using the information of the base station where the mobile communication terminal 30 is located or has transmitted and received a radio signal. This base station is a device included in the mobile communication network. For example, the position of the base station (for example, latitude and longitude) is stored in advance, and the position of the base station where the mobile communication terminal 30 is located is estimated as the position of the mobile communication terminal 30. Alternatively, based on information related to signal transmission / reception between the mobile communication terminal 30 and the base station, the distance between the mobile communication terminal 30 and the base station is calculated, and the position of the mobile communication terminal 30 is calculated from the distance. It is good to do. Base station positioning is advantageous in that the positioning time is shorter and the battery consumption of the mobile communication terminal 30 is less than that of geolocation positioning.

  However, in order to perform positioning of the mobile communication terminal 30 by base station positioning, the following two conditions may need to be satisfied. That is, first, the mobile communication terminal 30 needs to try to access the base station positioning server 50 (for example, the access to the base station positioning server 50 needs to be from the IP address of the mobile communication terminal 30). is there). Second, it is necessary that the mobile communication terminal 30 has a communication path to the base station server 50 (access to the base station positioning server 50). When the above conditions are not satisfied and the base station positioning fails, the user needs to try positioning with another positioning method again, and as a result, the time required for positioning may become long.

  The business operator that operates the base station positioning server 50 is, for example, a communication carrier that operates the positioning method determination device 1. The communication carrier does not enable base station positioning using the base station positioning server 50 for any mobile communication terminal, but only a mobile communication terminal of a specific communication type. In some cases, it may be desired to allow base station positioning using 50. Therefore, the communication carrier performs access control to the base station positioning server 50. Access control to the base station positioning server 50 can be performed by setting in the base station positioning server 50, for example. Specific settings in the base station positioning server 50 include a method of setting an accessible IP address bandwidth and a method of performing access control based on the accessor's user name. Thereby, it is necessary to satisfy the above conditions.

  For example, when access control to the base station positioning server 50 is performed in the IP address band, the communication carrier can access the base station positioning server 50 in a communication type that the base station positioning server 50 wants to access. Assign an IP address bandwidth that is The mobile communication terminal 30 that has attempted to access the base station positioning server 50 according to the communication type is assigned an IP address accessible to the base station positioning server 50, and thus can access the base station positioning server 50.

  Here, the communication type includes not only a large group such as 3G, LTE, and wireless LAN but also a type such as a specific communication service based on a contract between a user and a communication carrier. The specific communication service is realized by making the mobile communication terminal 30 accessible to a server that provides the communication service by a communication carrier. Some specific communication services include a base station positioning service. In addition, as a specific communication service, there is a service (for example, Internet provider service) that allows access to an external network. For example, when there are multiple communication services using a mobile communication network provided by a communication carrier, the service content that can be used by the user with these multiple communication services, the monthly fee required for use, etc. Here, it is assumed that each communication service is a different communication type. The user can use a service of the communication type by selecting a communication type to be used from a plurality of communication types provided by the communication carrier and making a contract with the communication carrier. The communication carrier defines an IP address band set in the mobile communication terminal 30 for each communication type.

  In addition, the mobile communication terminal 30 normally selects one of the communication types that can be used by the terminal itself, and performs communication according to the selected communication type. The mobile communication terminal 30 performs communication by accessing a connection destination indicated by an APN (Access Point Name) corresponding to the selected communication type. This selection may be performed automatically according to the situation of the mobile communication terminal 30 or may be performed by user input.

  In summary, the communication carrier defines an IP address band that can be accessed by the base station positioning server 50. Therefore, only the mobile communication terminal 30 to which the IP address in the IP address band is assigned can access the base station positioning server 50 (has a communication path to the base station positioning server 50). The communication carrier defines an IP address band to be assigned to each communication type, and the base station positioning server 50 is provided so that only the mobile communication terminal 30 related to the predetermined communication type can access the base station positioning server 50. An IP address bandwidth that can be accessed is assigned to the predetermined communication type. As described above, if the IP address is known, the communication type can be specified, and the presence or absence of a communication path (accessibility to the base station positioning server 50) can be determined from the communication type.

  With reference to FIG. 3, a description will be given of restrictions when positioning is performed by base station positioning. FIG. 3 is a diagram showing a base station positioning image. As described above, in the base station positioning, since the mobile communication terminal 30 needs to try to access the base station positioning server 50, the mobile communication terminal 30 accesses the base station positioning server 50 via the positioning method determining device 1. If it is attempted, positioning cannot be performed and position information cannot be acquired. Even if the mobile communication terminal 30 tries to access the base station positioning server 50 directly, the mobile communication terminal 30 is not a communication type that can access the base station positioning server 50 (to the base station positioning server 50). If it does not have a communication path), positioning cannot be performed.

  Geolocation positioning is a method of performing positioning of a mobile communication terminal by executing a geolocation API (Geolocation Application Program Interface) with Javascript (registered trademark) using a browser of the mobile communication terminal (for example, “W3C, Geolocation API Specification Editor's Draft (see @@@ forW3C Proposed Recommendation @@@) @@ May 2012). Javascript (registered trademark) is included in information (web page data) displayed by the browser. A mobile communication terminal that can use a browser that supports the geolocation API regardless of the communication type, communication carrier, or communication terminal (cell phone, tablet computer, etc.) There is an advantage that positioning is possible. However, geolocation positioning requires a long positioning time, and positioning accuracy varies.

  Based on the above, if the communication type is compatible, quick positioning is performed by performing base station positioning, and if the communication type is not compatible, positioning is performed reliably by performing geolocation positioning (positioning It is considered that an appropriate method for shortening the time required for positioning of the mobile communication terminal 30 is that the positioning operation due to the failure is not required. Since it cannot be determined from the browser whether or not the communication type corresponds to base station positioning, the positioning method determination device 1 determines the communication type by acquiring the IP address of the mobile communication terminal 30. Below, the detail of each function of the positioning method determination apparatus 1 is demonstrated.

  As shown in FIG. 1, the positioning method determination device 1 includes a communication path identification unit 11, an IP address storage unit 12, and a positioning method determination unit 13 as a configuration for determining a positioning method. Moreover, the positioning method determination apparatus 1 includes a positioning method output unit 14 as a configuration for outputting information for specifying the positioning method. Moreover, the positioning method determination apparatus 1 includes an application execution unit 15 as a configuration for executing an application based on the acquired position information. Note that a positioning method determination device is a device that includes only a configuration for determining a positioning method without a configuration for executing an application based on position information, and a configuration for outputting information for specifying a positioning method. You can also

  First, a configuration for determining a positioning method will be described. The communication path specifying unit 11 is a communication path specifying unit that receives the position information acquisition request transmitted from the mobile communication terminal 30 and specifies the communication path of the mobile communication terminal 30. The communication path is specified by the communication type of the mobile communication terminal 30. Therefore, the communication path is specified by specifying the communication type of the mobile communication terminal 30. Since the IP address used for each communication type is managed in the IP address storage unit 12 described later, the communication type is specified by specifying the IP address of the mobile communication terminal 30. Therefore, the communication path specifying unit 11 specifies the communication type by acquiring the IP address of the mobile communication terminal 30, and further specifies the communication path from the communication type.

  The communication path specifying process by the communication path specifying unit 11 will be described with reference to FIG. FIG. 2 is a diagram for explaining channel identification based on the IP address by the channel identification unit 11.

  The acquisition of the IP address of the mobile communication terminal 30 by the communication path specifying unit 11 is performed when a location information acquisition request is received from the mobile communication terminal 30. The acquisition of the IP address can be performed by a conventional technique. As shown in FIG. 2, the mobile communication terminal 30 communicates with a private IP address when the mobile communication terminal 30 is in the internal network of the communication carrier related to the contracted communication type. When accessing an external network (for example, the Internet), a global IP address is assigned and communication is performed. The IP address acquired by the communication path specifying unit 11 is a global IP address.

  The communication path specifying unit 11 specifies the communication type of the mobile communication terminal 30 from the acquired IP address of the mobile communication terminal 30 by searching the communication type / IP address correspondence table stored in the IP address storage unit 12. . An example of the communication type / IP address correspondence table stored in the IP address storage unit 12 is shown in FIG. As shown in FIG. 4A, the communication type / IP address correspondence table is used when the mobile communication terminal 30 accesses the Internet with each communication type (communication types A to C in FIG. 4A). The bandwidth of the IP address to be performed is described. In the example of FIG. 4A, for example, if the acquired IP address is “1.66.96.4”, the IP address is within the IP address band of the communication type A (“1. 66.96.0 / 21 "), the communication path identifying unit 11 identifies the communication type A of the mobile communication terminal 30.

  After specifying the communication type, the communication path specifying unit 11 specifies the communication path from the specified communication type. The communication path specifying unit 11 holds a communication type / base station positioning server access correspondence table shown in FIG. The communication path specifying unit 11 specifies whether or not the communication path is accessible to the base station positioning server 50 from the acquired communication type and the communication type / base station positioning server access correspondence table. In the communication type / base station positioning server access correspondence table shown in FIG. 4B, if the communication type is A, it is a communication path that can access the base station positioning server 50 (a communication path capable of positioning by base station positioning). If it is specified that there is a communication type other than that (communication type B, communication type C), it is specified that the communication path is not accessible to the base station positioning server (a communication path in which positioning by base station positioning is impossible). To do. When it is specified that the communication path cannot be determined by base station positioning, the communication path is specified as a communication path that performs positioning by geolocation positioning. The communication path specifying unit 11 inputs the specified communication path to the positioning method determining unit 13.

  As described above, the IP address storage unit 12 stores a communication type / IP address correspondence table. In the communication type / IP address correspondence table shown in FIG. 4A, not only the correspondence table with the communication type IP address capable of base station positioning, but also the IP address of the communication type capable of base station positioning. However, since the communication path specifying unit 11 only needs to know whether or not the base station positioning is possible, it is also possible to store only the correspondence table with the IP address of the communication type capable of base station positioning. Good.

  The positioning method determination unit 13 is a positioning method determination unit that determines a positioning method according to the communication path of the mobile communication terminal 30 input by the communication path specifying unit 11. The positioning method determination unit 13 stores the communication path and the positioning method in association with each other, and determines the positioning method based on the associated information. Specifically, a communication path capable of positioning by base station positioning and a base station positioning are linked and stored, and a communication path in which positioning by base station positioning is impossible (communication that performs positioning by geolocation positioning) Road) and geolocation positioning. When the communication channel specifying unit 11 specifies that the communication channel is a communication channel that can be measured by base station positioning, the positioning method determination unit 13 determines the positioning method to be base station positioning. In addition, when the communication path specifying unit 11 specifies that the communication path is a communication path for performing positioning by geolocation positioning, the positioning method determining unit 13 determines the positioning method to be geolocation positioning. The positioning method determination result by the positioning method determination unit 13 is input to the positioning method output unit 14.

  Next, a configuration for outputting information for specifying a positioning method will be described. The positioning method output unit 14 is a positioning method output unit that outputs the positioning method determination result (information specifying the positioning method) input by the positioning method determination unit 13. For example, the positioning method output unit 14 transmits a positioning method determination result to the mobile communication terminal 30 and instructs to perform positioning using the determined positioning method.

  The positioning method output unit 14 generates an HTTP redirect in response to an input from the positioning method determination unit 13 when the positioning method determination unit 13 determines that the positioning method is base station positioning. Before the HTTP redirect is generated, the mobile communication terminal 30 accesses the positioning method determination device 1 from the URL using a browser. The HTTP redirect is a function for notifying that the URL has been changed, and the information for notifying that the URL has been changed includes the URL after the change. In the example of the present embodiment, the URL is changed from the URL for accessing the positioning method determination device 1 to the URL for accessing the base station positioning server 50. The browser of the mobile communication terminal 30 can access the base station positioning server 50 by referring to the HTTP redirect and reading the redirect destination URL. When the HTTP redirect is generated, the positioning method output unit 14 includes the HTTP redirect in the positioning method determination result transmitted to the mobile communication terminal 30.

  When receiving the above HTTP redirect, the mobile communication terminal 30 accesses the base station positioning server 50 from the browser by the HTTP redirect. Thereby, the positioning of the mobile communication terminal 30 is performed by the base station positioning server 50, and the mobile communication terminal 30 acquires the position information of the own terminal.

  The positioning method output unit 14 generates information including a program for executing positioning such as Javascript (registered trademark) that executes the geolocation API when the positioning method determination unit 13 determines the positioning method to be geolocation positioning. Then, the data is transmitted to the mobile communication terminal 30. The mobile communication terminal 30 receives the information, reads the information with a browser, and executes a geolocation API using Javascript (registered trademark). Thereby, geolocation positioning is performed and the mobile communication terminal 30 acquires the position information of the own terminal. This is the end of the description of the configuration for outputting the information for specifying the positioning method.

  Next, a configuration for executing an application based on the acquired position information will be described. When the positioning method determination result is transmitted to the mobile communication terminal 30 and the positioning of the mobile communication terminal 30 is performed by base station positioning or geolocation positioning, the positioning result is transmitted from the mobile communication terminal 30 to the positioning method determination device 1. .

  The application execution unit 15 executes the application using the position information that is the positioning result transmitted from the mobile communication terminal 30. The application executed by the application execution unit 15 is, for example, posted by a user in the vicinity of the user of the mobile communication terminal 30 from an information service site (for example, Twitter (registered trademark)) where the user posts and browses a short sentence. If it is an application that searches and displays only (peripheral tweet search), it is possible to search and display the tweet of the user's peripheral users by using the positional information that is the positioning result. Specifically, the application execution unit 15 acquires in advance posts from sites such as Twitter (registered trademark), sorts them into predetermined locations (for example, prefectures), and stores the position information as positioning results. From, a post of a place where the user is located (for example, a prefecture) is displayed. This is the end of the description of the configuration for executing the application based on the acquired position information.

  In addition, as an example of the application to be executed, a tweet at a specific position among tweets related to a television program may be searched and displayed.

  Next, the mobile communication terminal 30 will be described. The mobile communication terminal 30 is a terminal such as a mobile phone used by a user. When the user using the mobile communication terminal 30 performs a real-time search, a location information acquisition request is transmitted from the mobile communication terminal 30 to the positioning method determination device 1, and processing by each function of the positioning method determination device 1 described above is executed. The The mobile communication terminal 30 includes a position information acquisition unit 31 and a geolocation execution availability determination unit 32.

  The location information acquisition unit 31 acquires location information of the mobile communication terminal 30 in cooperation with the positioning method determination device 1 and the base station positioning server 50. The function by the position information acquisition unit 31 is executed by the browser. The position information acquisition unit 31 transmits a position information acquisition request to the positioning method determination apparatus 1 based on an operation related to a user's real-time search. Further, the position information acquisition unit 31 receives the positioning method determination result transmitted from the positioning method output unit 14 of the positioning method determination device 1. If the positioning method determination result is to perform positioning by base station positioning, information related to HTTP redirect in which a URL for accessing the base station positioning server 50 is set in the positioning method determination result is included. Therefore, the position information acquisition unit 31 makes a base station positioning request to the base station positioning server 50. Processing related to positioning by the base station positioning server 50 will be described later. On the other hand, if the positioning method determination result is a result of positioning by geolocation, the position information acquisition unit 31 inputs the positioning method determination result to the geolocation execution possibility determination unit 32. Processing related to positioning by the geolocation execution possibility determination unit 32 will be described later.

  The position information acquisition unit 31 transmits the positioning result received from the base station positioning server 50 or the positioning result input from the geolocation execution availability determination unit 32 to the positioning method determination device 1.

  The geolocation execution feasibility determination unit 32 determines whether or not the geolocation positioning by the mobile communication terminal 30 can be performed with the input of the positioning method determination result by the position information acquisition unit 31 as a trigger. Determining whether or not geolocation positioning can be performed means determining whether or not the mobile communication terminal 30 can execute the geolocation API using Javascript (registered trademark). It is determined whether the browser that can be used by the terminal 30 is a geolocation API-compatible browser or whether the user is permitted to use the geolocation API. When the mobile communication terminal 30 can execute the geolocation API, the geolocation execution availability determination unit 32 executes the geolocation API with Javascript (registered trademark) and acquires the position information of the mobile communication terminal 30 ( Positioning). The geolocation execution possibility determination unit 32 inputs the positioning result of the mobile communication terminal 30 to the position information acquisition unit 31.

  Next, the base station positioning server 50 will be described. The base station positioning server 50 receives a base station positioning request from the mobile communication terminal 30 and executes base station positioning. Here, it is assumed that the base station positioning server 50 can execute a base station positioning method that has been conventionally performed. The base station positioning server 50 transmits the execution result of base station positioning to the mobile communication terminal 30.

  Next, the hardware configuration of the positioning method determination apparatus 1 will be described with reference to FIG. FIG. 4 is a diagram illustrating a hardware configuration of the positioning method determination apparatus 1 according to the embodiment of the present invention. As shown in FIG. 4, the positioning method determination apparatus 1 includes a computer including hardware such as a CPU 101, a RAM 102 and a ROM 103 that are main storage devices, a communication module 104 for performing communication, and an auxiliary storage device 105 such as a hard disk. Configured to include. Each of the above-described functions is exhibited when these components are operated by a program or the like.

  Subsequently, the processing sequence of the positioning method determination apparatus 1, the mobile communication terminal 30, and the base station positioning server 50 will be described with reference to the sequence diagram of FIG.

  First, when a user performs an operation related to real-time search from the mobile communication terminal 30, a position information acquisition request is transmitted from the position information acquisition unit 31 of the mobile communication terminal 30 to the positioning method determination device 1 (S101). Subsequently, the IP address of the mobile communication terminal 30 is acquired by the communication path specifying unit 11 of the positioning method determining apparatus 1, and the communication path is determined (specified) depending on whether or not the IP address is within a preset band. (S102, communication channel specifying step). Then, the positioning method is determined by the positioning method determination unit 13 according to the specified communication path. If the communication path is identified as a communication path that can be measured by base station positioning, the positioning method is determined to be base station positioning (S103, positioning method determination step).

  When the positioning method is determined to be base station positioning, an HTTP redirect in which the redirect destination URL is set is generated by the positioning method output unit 14 (S104), and the HTTP redirect is included, but the positioning method determination result is the positioning. It is transmitted from the method output unit 14 to the mobile communication terminal 30 (S105, positioning method output step). The mobile communication terminal 30 receives the positioning method determination result, and accesses the base station positioning server 50 (transmits the base station positioning request) from the redirect destination URL (S106). The base station positioning server 50 receives the base station positioning request and executes base station positioning (S107). And the positional information which is a positioning result is returned to the mobile communication terminal 30 from the positioning base station positioning server 50 (S108).

  The mobile communication terminal 30 receives the position information returned from the base station positioning server 50, and the position information is transmitted from the position information acquisition unit 31 to the positioning method determination device 1 (S109). And the said positional information is acquired by the positioning method determination apparatus 1 (S110).

  On the other hand, if the channel is a channel that cannot be measured by base station positioning and is identified as a channel that performs positioning by geolocation positioning, the positioning method is determined to be geolocation positioning. (S111, positioning method determination step). When the positioning method is determined to be geolocation positioning, the positioning method determination result is transmitted from the positioning method output unit 14 to the mobile communication terminal 30 (S112, positioning method output step). The positioning method determination result is received by the mobile communication terminal 30, and the geolocation execution availability determination unit 32 of the mobile communication terminal 30 determines whether or not the browser is a geolocation compatible browser (S113), and whether or not the user is permitted to use the geolocation. (S114) is determined. If the conditions of S113 and S114 are satisfied, geolocation positioning is executed with the geolocation API (S115).

  Thereafter, whether or not the position information can be appropriately acquired is determined by the geolocation execution determination unit 32 (S116). If the position information is acquired, the positioning method determination device 31 determines whether the position information is acquired. The positioning result is transmitted to 1 and the position information is acquired by the positioning method determining apparatus 1 (S117). If the conditions of S113 and S114 are not satisfied, and if the position information cannot be acquired in S116, positioning fails (S118).

  When the positioning method determination device 1 can acquire the position information, the application execution unit 15 executes the application using the position information that is the positioning result (S119).

Identified If the positioning method is determined to be geolocation positioning, base station positioning is performed if base station positioning with a short positioning time is possible, and geolocation positioning is performed if positioning is not possible with base station positioning. Positioning can be performed. That is, quick positioning is realized by determining an optimal positioning method for the mobile communication terminal 30.
