## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a Continuation Application of U.S. patent application Ser. No. 14/472,577 filed on Aug. 29, 2014, which claims priority to Japanese Patent Application No. 2014-090718 filed on Apr. 24, 2014, the entire contents of which are incorporated herein by reference.


BACKGROUND
(a) Field
The present invention generally relates to a mobile terminal, an access point related content providing server, an access point related content acquiring method, and a mobile terminal program for providing location information based content.
(b) Description of the Related Art
In recent years, with spread of high-performance mobile terminals called smartphones or tablets, it is explosively increased to use contents as users move. Further, contents that users expect to browse in many places are increasing.
On the other hand, many of users are currently browsing web contents using search engines, and so-called pull-type content provision in which the users see what they want to see becomes the mainstream. However, in this case, a problem that precious contents do not provided to the users occurs.
To solve this problem, a recommendation system has been developed. The recommendation system performs a recommendation using the user's attributes without performing pre-registration for the user by using acquired face image of the user.
For example, Japanese Patent Publication No. 2013-073420 discloses that a mobile terminal acquires a user's face image and extracts a feature quantity from the acquired user's face image. Then, the mobile terminal transmits the extracted feature quantity to a recommendation server. The recommendation server receives the feature quantity from the mobile terminal, stores at least a plurality of feature quantities, performs matching processing of the received feature quantity with the stored feature quantities, recommends an application or the like on the basis of the matching result, and transmits the recommendation result to the mobile terminal. The mobile terminal receives the recommendation result from the recommendation server, and displays the received recommendation result.
However, since the recommendation is performed based on individual information such as the face in the above reference, it is impossible to perform the recommendation based on environment information such as location or time zone.

Access Point Related Content Providing Process
FIG. 4 is a flowchart of an access point related content providing process executed by a mobile terminal 10, an access point related content providing server 200, and a web server 300. Processes executed by the modules of each device described above are described in conjunction with the present procedure.
First, the access point communication module 13 of the mobile terminal 10 starts a communication with an access point (Step S11). Here, the access point is a device that performs a communication for accessing the public network via the wireless communication.
Next, the IP address acquisition module 14 of the mobile terminal 10 acquires an IP address of the access point to which the mobile terminal 10 is connected (Step S12). Here, the IP address indicates a global IP address not a private IP address. In the case that the access point does not have the global IP address, the mobile terminal 10 may acquire an IP address of a router to which the access point is connected.
Subsequently, the IP address transmission module 15 of the mobile terminal 10 transmits the acquired IP address to the access point related content providing server 200 (Step S13). The requestor IP address reception module 204 of the access point related content providing server 200 receives the IP address transmitted from the mobile terminal 10, i.e., a requestor (Step S14).
The location information identification module 206 of the access point related content providing server 200 identifies a current location of the mobile terminal 10 based on the received IP address (Step S15).
Next, the related content extraction module 207 of the access point related content providing server 200 extracts from the access point related content database 250 an URL of a content associated with the received IP address (Step S16).
FIG. 7 shows an example of an access point related content table in an access point related content database 250. In the access point related content table, IP addresses of access points, names of the contents, URLs of the contents, and weights of the contents are associated with each other and are stored.
Regarding the IP address, the IP address may be represented as a pattern by using a percent sign % indicating any of a plurality of numbers, like an example of “200.168.9.1%”. For example, the IP address of “200.168.9.11”, “200.168.9.151”, or “200.168.9.1” may allocated to the IP address of “200.168.9.1%”. When a plurality of contents are extracted at the extraction of the related content, a content with the largest weight may be extracted from among the plurality of contents with reference to the weights associated with the contents. Alternatively, a content having the highest conformity according to the pattern may be extracted.
Further, the proximity content extraction module 208 of the access point related content providing server 200 extracts from the location related content database 251 a content associated with location information that is within a predetermined range from the identified location information (Step S16).
FIG. 8 shows an example of a location related content table in a location related content database 251. In the location related content table, location information, URLs of the contents, and weights of the contents are associated with each other and are stored. Here, the location information is represented by latitude and longitude. Alternatively, the location information may be represented by a place name, a building name, or an identifier thereof.
The proximity content extraction module 208 of the access point related content providing server 200 extracts the location information that is within a predetermined range from the identified location information, and extracts from the location related content table the content that is associated with the extracted location information. When a plurality of contents are extracted, a content having the largest weight may be extracted with reference to the weights. Alternatively, a content having the shortest length from the identified location information may be extracted.
The access point related content providing module 205 of the access point related content providing server 200 transmits the URL of the extracted content to the mobile terminal 10 (Step S17).
The URL reception module 16 of the mobile terminal 10 receives the URL of the content (Step S18), the content acquisition module 17 transmits a request for the content to the web server 300 designated as an access destination by the URL (Step S19).
When receiving the request (Step S20), the web content providing module 303 of the web server 300 transmits a web page, an image, a video, or streaming corresponding to the request as a response (Step S21). The content acquisition module 17 of the mobile terminal 10 receives the web page, the image, the video, or the streaming (Step S22). The mobile terminal 10 may play or execute the received content. When the received content is an application, the mobile terminal 10 may automatically install the received application.
FIG. 5 shows an example of a display unit of a mobile terminal 10 displaying a received content. In FIG. 5, the acquired URL is displayed in an address bar 51, and the received content is displayed in a window 52. A wireless communication icon 53 is displayed and indicates that the mobile terminal 10 is connected to a certain access point.
FIG. 6 is a schematic diagram showing a case that a mobile terminal 10 changes an access point to which it is connected. In FIG. 6, IP addresses 61 and 62 are allocated to access points 20A and 20B, respectively, and the access points 20A and 20B are installed in buildings 63 and 64, respectively.
First, if the mobile terminal 10 connects to the access point 20A, the mobile terminal 10 receives a content 65 associated with the IP address 61 from the access point related content providing server 200 and displays the content 65. Next, if the mobile terminal 10 moves along a path 67 and connects to the access point 20B, the mobile terminal 10 receives a content 66 associated with the IP address 62 from the access point related content providing server 200 and displays the content 66. A resident application of the mobile terminal 10 may monitor these procedures.
The above disclosure is the procedure of the access point related content providing process executed by the mobile terminal 10, the access point related content providing server 200, and the web server 300.
The above-described means and functions are realized by reading and executing a predetermined program by a computer (including a CPU, an information processing apparatus, and various terminals). The program is recorded in a (non-transitory) computer-readable recording medium, for example, a flexible disk, a CD (e.g., a CD-ROM or the like) and a DVD (e.g., a DVD-ROM, a DVD-RAM, or the like). In this case, the program is read from the recording medium by a computer and transmitted to an internal storage unit or an external storage unit to be stored and executed. Further, the program may be pre-stored in a storage unit (recording medium) such as a magnetic disk, an optical disk, or an optical magnetic disk and transmitted from the recording medium to a computer through a communications line.
