(Embodiment)
[1. Estimate processing]
First, an example of the estimation process according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an example of estimation processing according to the embodiment. In the example shown in FIG. 1, a case is shown in which an advertisement is delivered to a user according to the user's position information estimated by the estimation device 100. Specifically, in the example shown in FIG. 1, the case where the advertisement is delivered to the user according to the area where the user estimated by the estimation device 100 is located is shown. The area referred to here is an area of a size that is difficult to estimate when there is an error of several km in the user's position information, that is, an area of a size that can be accommodated in a plurality of areas of several km. May be good. For example, the area referred to here may be, for example, an area smaller than a unit such as a prefecture, such as "Roppongi" or "Shibuya".

As shown in FIG. 1, the estimation system 1 includes a terminal device 10 and an estimation device 100. The terminal device 10 and the estimation device 100 are communicably connected by wire or wirelessly via a predetermined network. The estimation system 1 shown in FIG. 1 may include a plurality of terminal devices 10 and a plurality of estimation devices 100.

The terminal device 10 is an information processing device used by the user. The terminal device 10 requests information from the estimation device 100 and other external devices according to the operation by the user, and displays the information acquired from the estimation device 100 and other external devices. For example, the terminal device 10 requests an advertisement from the estimation device 100 according to an operation by the user, and displays the advertisement acquired from the estimation device 100. In the following, the terminal device 10 may be referred to as a user. That is, in the following, the user can be read as the terminal device 10. The terminal device 10 described above is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like.

The estimation device 100 is an information processing device that estimates the user's position information in one communication based on the information related to one communication. Further, when the determination based on the information related to one communication does not satisfy the predetermined condition, the estimation device 100 obtains the position information different from the position information estimated based on the information related to one communication from the terminal device 10. Other location information estimated based on information related to other communications is used as the user's location information in one communication. The "user's position information in one communication" here means, for example, the user's position information at the time of one communication and the user's position information at the time of one communication. Further, the term "different" in "position information different from the position information estimated based on the information related to one communication" means a difference in the acquisition (estimation) mode of each position information. That is, "position information different from the position information estimated based on the information related to one communication" does not exclude the case where the contents of the position information (for example, latitude / longitude, area, etc.) coincide with each other by chance. For example, the estimation device 100 is based on the content of position information estimated based on information on one communication (communication according to the communication standard of the terminal device 10) and information on other communication (for example, communication of a predetermined wireless LAN). Even if the contents of the estimated other location information coincide with each other by chance, the other location information is used as the user's location information in one communication.

Further, the estimation device 100 shall provide an advertisement distribution service that distributes an advertisement according to the user's position information in one estimated communication. When the advertisement distribution device is separate from the estimation device 100, the advertisement distribution device distributes the advertisement to the user's terminal device 10 based on the user's position information in one communication estimated by the estimation device 100. In this case, the estimation system 1 includes an advertisement distribution device, and the estimation device 100 may distribute the user's position information in one estimated communication to the advertisement distribution device. Further, the estimation device 100 may deliver contents other than advertisements.

In the example shown in FIG. 1, the terminal device 10 communicates with a terminal device 10 such as a 3rd generation mobile communication system (hereinafter, also referred to as “3G”) or a 4th generation mobile communication system (hereinafter, also referred to as “4G”). It is assumed that communication is performed with the estimation device 100 by selectively using either a communication method according to a standard or a communication method of a predetermined wireless LAN such as Wi-Fi (registered trademark) (Wireless Fidelity). In the following, a case where the predetermined wireless LAN is Wi-Fi and the communication method according to the communication standard of the terminal device 10 is 3G (hereinafter, also referred to as “3G communication”) will be described as an example. In the example of FIG. 1, for the sake of simplicity, the information communicated between the terminal device 10 used by the user U1 and the estimation device 100 includes the position information of the terminal device 10 detected by GPS. (Hereinafter, it may be referred to as "GPS information") is not included. For example, it is assumed that the position information of GPS information has a smaller error than the position information that can be estimated by a communication method such as 3G communication or Wi-Fi communication. In this case, the position information of GPS information is more accurate than the position information that can be estimated by a communication method such as 3G communication or Wi-Fi communication.

The accuracy of the user's position information that can be estimated by the communication method according to the communication standard of the terminal device 10 is based on, for example, the position of the base station (base station BS11 in FIG. 1) of the communication carrier, so the accuracy is in units of several kilometers. And. Therefore, when the terminal device 10 communicates by the communication method according to the communication standard of the terminal device 10, the estimation device 100 estimates the area because the error of the user's position information in the communication estimated from the information about the communication method is large. Difficult to do. Therefore, when the terminal device 10 communicates by the communication method according to the communication standard of the terminal device 10, the estimation device 100 cannot estimate the user's position information in the communication from the information related to the communication method. The communication method according to the communication standard of the terminal device 10 is limited to 3G or 4G if the accuracy of the user's position information that can be estimated by the communication method is several kilometers or the like and it is difficult to estimate the area where the user is located. However, any communication method may be used.

Further, the accuracy of the user's position information that can be estimated by the Wi-Fi communication method of the terminal device 10 is based on, for example, the position of an access point (access point AP11 or the like in FIG. 1), so the accuracy is in units of several tens of meters. And. Therefore, when the terminal device 10 communicates by the Wi-Fi communication method, the estimation device 100 can estimate the area from the user's position information in the communication estimated from the information about the communication method. Therefore, when the terminal device 10 communicates by the Wi-Fi communication method, the estimation device 100 can estimate the user's position information in the communication from the information related to the communication method. The Wi-Fi communication method is not limited to Wi-Fi as long as the accuracy of the user's position information that can be estimated by the communication method is several tens of meters or the like and the area where the user is located can be estimated. Any communication method may be used. As described above, it is assumed that the position information that can be estimated by the communication method of Wi-Fi communication has a smaller error than the position information that can be estimated by the communication method of 3G communication. In this case, the position information that can be estimated by the communication method of Wi-Fi communication is more accurate than the position information that can be estimated by the communication method of 3G communication.

Further, when the estimation device 100 estimates the user's position information by the Wi-Fi communication method, the estimation device 100 uses the information about the position where each Wi-Fi access point (access point AP11 or the like in FIG. 1) is installed. For example, the estimation device 100 estimates the user's position information based on the Wi-Fi access point information used by the terminal device 10 in communication and the information on each access point and its installation position. That is, it is assumed that the estimation device 100 can acquire information on Wi-Fi access points and information on each access point and its installation position.

In the example of FIG. 1, it is assumed that the estimation device 100 has acquired the information shown in the access point information storage unit 124. For example, the access point identified by the access point ID "AP11" (corresponding to the access point AP11 in FIG. 1) indicates that it is installed in the area A. In the example of FIG. 1, for the sake of simplicity, it is assumed that the terminal device 10 for Wi-Fi communication using the access point AP11 is located in the area A. The user's position information during Wi-Fi communication is not limited to the above, and various techniques for position estimation by Wi-Fi may be used.

In the example of FIG. 1, it is assumed that the estimation device 100 has an advertisement as shown in the advertisement information storage unit 123. Here, the "target area" in FIG. 1 indicates information about the area (region) targeted by the corresponding advertisement. For example, the "target area" may be specified by the advertiser. Further, the "target area" may be attached to the estimation device 100 based on the content of the advertisement. A plurality of "target areas" may be stored. For example, the estimation device 100 determines an advertisement to be delivered to the user based on the comparison between the "target area" of each advertisement and the user's area in the estimated communication.

First, in the example of FIG. 1, the estimation device 100 acquires an advertisement request from the terminal device 10-1 used by the user U1 (step S11). For example, the terminal device 10-1 requests the estimation device 100 to display an advertisement in a predetermined advertising space in the content. The advertisement request acquired by the estimation device 100 from the terminal device 10-1 includes information on the communication method (for example, information indicating whether it is Wi-Fi or 3G) and information on the access point used (for example, the access point AP11). Information related to communication such as information indicating that it is the nearest access point) shall be included.

The terminal devices 10-1 and 10-2 shown in FIG. 1 have different reference numerals to indicate that the timing of requesting the advertisement is different, but may be the same terminal device 10. In the following, when the terminal devices 10-1 and 10-2 are described without distinction, they may be referred to as the terminal device 10. Further, in FIG. 1, for simplification of the explanation, the estimation device 100 shall acquire information that can identify the terminal device 10 (that is, the user U1) from the terminal device 10 at the time of communication with the terminal device 10. ..

In the communication in step S11, the terminal device 10-1 transmits an advertisement request to the estimation device 100 by Wi-Fi communication. In this case, for example, the icon IC11 indicating that the communication method at that time is Wi-Fi is displayed on the screen of the terminal device 10-1. In the example of FIG. 1, the terminal device 10-1 transmits an advertisement request to the estimation device 100 by Wi-Fi communication using the access point AP11. For example, the estimation device 100 makes a determination based on information regarding an advertisement request (one communication). In this case, assuming that the estimation device 100 satisfies a predetermined condition because the communication obtained from the terminal device 10-1 is Wi-Fi communication, the information regarding the communication in step S11, that is, the information included in the advertisement request is used. Based on this, the area where the user U1 is located is estimated as the area A.

In the example of FIG. 1, the estimation device 100 estimates the area where the terminal device 10-1 (that is, the user U1) requesting the advertisement is located (step S12). For example, the estimation device 100 estimates the area where the user U1 is located as the area A based on the information indicating that the access point AP11 stored in the access point information storage unit 124 is installed in the area A.

Then, the estimation device 100 determines the advertisement to be delivered to the terminal device 10-1 based on the area of the user estimated in step S12 (step S13). In the example of FIG. 1, since the estimation device 100 estimates that the user U1 is located in the area A, among the advertisements stored in the advertisement information storage unit 123, the advertisement whose target area is the "area A" is the terminal device 10-. Determined as an advertisement to be delivered to 1. When there are a plurality of advertisements whose target area is "region A", the estimation device 100 may be determined as an advertisement to be delivered to the terminal device 10-1 in consideration of other information. For example, when there are a plurality of advertisements whose target area is "Region A", the estimation device 100 may determine the advertisement having the highest bid price as the advertisement to be delivered to the terminal device 10-1.

In the example of FIG. 1, the estimation device 100 determines the advertisement A whose target area is the "region A" as an advertisement to be delivered to the terminal device 10-1. After that, the estimation device 100 delivers the advertisement A to the terminal device 10-1 (step S14). Then, the terminal device 10-1 that has received the advertisement A displays the advertisement A.

Further, in the example of FIG. 1, the estimation device 100 acquires an advertisement request from the terminal device 10-2 used by the user U1 (step S21). Specifically, the estimation device 100 acquires an advertisement request from the terminal device 10-2 used by the user U1 at 9 pm on Saturday night. For example, the terminal device 10-2 requests the estimation device 100 to display an advertisement in a predetermined advertising space in the content.

In the communication in step S21, the terminal device 10-2 transmits an advertisement request to the estimation device 100 by 3G communication. In this case, for example, the icon IC12 indicating that the communication method at that time is 3G is displayed on the screen of the terminal device 10-2. In the example of FIG. 1, the terminal device 10-2 transmits an advertisement request to the estimation device 100 by 3G communication using the base station BS11.

After that, the estimation device 100 estimates the area where the terminal device 10-2 (that is, the user U1) requesting the advertisement is located (step S22). In the example of FIG. 1, the estimation device 100 estimates the area where the terminal device 10-2 (ie, user U1) is located at 9 pm on Saturday.

For example, the estimation device 100 makes a determination based on information regarding an advertisement request (one communication). As described above, when the terminal device 10 communicates by the communication method according to the communication standard of the terminal device 10 such as 3G communication, the estimation device 100 estimates the user's position information in the communication from the information related to the communication method. Can't. Therefore, the estimation device 100 assumes that the communication obtained from the terminal device 10-2 is 3G communication and does not satisfy the predetermined condition, and the information related to the communication in step S21, that is, information other than the information included in the advertisement request. Based on, the user's position information in the communication is estimated.

In the example of FIG. 1, the estimation device 100 estimates the user's position information in the communication based on the history information stored in the user information storage unit 121. For example, the history information stored in the user information storage unit 121 indicates an action pattern relating to which time zone and which area the user is in on weekdays and weekends. For example, the estimation device 100 acquires historical information based on the user's position information or the like acquired in the past. In the example of FIG. 1, a case is shown in which the time zone is divided into four time zones: morning (4 to 10 o'clock), noon (10 to 16 o'clock), night (16 to 22 o'clock), and midnight (22 to 4 o'clock). , The time zone division may be another division (for example, division into 24 for each time). Further, in the example of FIG. 1, the case where it is divided into two types, weekdays and weekends, is shown, but the types are seven types according to each day of the week such as "Monday", "Tuesday", and "Wednesday". May be good.

In the example shown in the user information storage unit 121 in FIG. 1, the user U1 is likely to be located in the area A during the morning hours of the weekend. Also, for example, user U1 indicates that it is likely to be located in region C during the daytime hours of the weekend. Also, for example, user U1 indicates that it is likely to be located in region D during weekend night hours. Also, for example, user U1 indicates that it is likely to be located in region A during the midnight hours of the weekend.

Therefore, the estimation device 100 delivers the advertisement to the terminal device 10-2 based on 9 pm on Saturday, which is the time zone when the user U1 requests the advertisement, and the history information stored in the user information storage unit 121. Determine (step S23). In the example of FIG. 1, the estimation device 100 estimates that the user U1 is likely to be located in the area D at 9:00 on Saturday night based on the history information stored in the user information storage unit 121. Therefore, the estimation device 100 estimates that the user U1 is located in the area D, and among the advertisements stored in the advertisement information storage unit 123, delivers the advertisement whose target area is the "region D" to the terminal device 10-2. Determined as an advertisement.

In the example of FIG. 1, the estimation device 100 determines the advertisement D whose target area is the “region D” as an advertisement to be delivered to the terminal device 10-2. After that, the estimation device 100 delivers the advertisement D to the terminal device 10-2 (step S24). Then, the terminal device 10-2 that has received the advertisement D displays the advertisement D.

As described above, the estimation device 100 can appropriately estimate the user's position information even when the information used for estimating the user's position information is not sufficient. Then, the estimation device 100 can deliver the advertisement suitable for the area where the user is located by delivering the advertisement to the terminal device 10 based on the estimated position information of the user.

The estimation device 100 may deliver an advertisement in which user attributes are added. For example, the estimation device 100 may deliver an advertisement to the terminal device 10 in which the area where the user is located and the target area match, and the attributes of the user and the target attribute match. Further, in the above-mentioned example, in order to simplify the explanation, the case where the user who uses the terminal device 10 is specified is shown, but in each communication, the user communicates by appropriately using various conventional techniques. The user who uses the terminal device 10 may be specified.

For example, the user information storage unit 121 may store information regarding the demographic attribute and information regarding the psychographic attribute of the user. For example, the user information storage unit 121 may store information such as a name, family structure, income, interests, and lifestyle.

(Communication information storage unit 122)
The communication information storage unit 122 according to the embodiment stores various information related to communication. FIG. 4 is a diagram showing an example of the communication information storage unit according to the embodiment. FIG. 4 shows a case where information related to communication for each user is stored in the communication information storage unit 122. As shown in FIG. 4, the communication information storage unit 122 has items such as "user ID", "communication ID", "date and time", "communication status", "GPS information", and "location information" as information related to communication. included.

The "user ID" indicates identification information for identifying a user. The "communication ID" indicates identification information for identifying the communication. The "date and time" indicates the date and time when the corresponding communication was performed. In the example of FIG. 4, the information stored in the "date and time" is illustrated by a code such as "date and time DA", but the "date and time" includes "August 3, 2016 12:10:43" and the like. It is assumed that the specific date and time of is memorized.

Further, the "communication status" indicates information regarding the communication method in the corresponding communication. For example, the communication method "method A" is a communication method using a predetermined wireless LAN (for example, Wi-Fi). For example, the communication method "method B" is a communication method based on the communication standard (for example, 3G) of the terminal device 10. Further, the "GPS information" indicates whether or not the GPS information related to the terminal device 10 is included in the information communicated in the corresponding communication. "Location information" indicates the user's location information in the corresponding communication. For example, “location information” indicates information about the area where the user is estimated to be located during the corresponding communication. The position information stored in the "position information" may be information related to latitude and longitude, an address, or the like.

For example, in the example shown in FIG. 4, the communication by the terminal device 10 used by the user U1 and the communication identified by the communication ID "CN1" (hereinafter, may be referred to as "communication CN1") is the date and time. Indicates that it was done to DA. Further, the communication CN1 indicates that the communication was performed by the method A. Further, it indicates that the information communicated by the communication CN1 does not include the GPS information of the terminal device 10. Further, the location information of the user in the communication CN1 indicates that the area A is estimated. In the example of FIG. 4, the estimation device 100 estimates the user's position information in the communication CN1 as the area A based on the information indicating the position of the area A where the access point AP11 used for the communication of the method A is located.

For example, in the example shown in FIG. 4, the communication by the terminal device 10 used by the user U1 and the communication identified by the communication ID "CN2" (hereinafter, may be referred to as "communication CN2") is the date and time. It shows that it was done in the date and time DB after DA. Further, the communication CN2 indicates that the communication was performed by the method B. Further, it indicates that the information communicated by the communication CN2 does not include the GPS information of the terminal device 10. Further, the location information of the user in the communication CN2 indicates that the area A is estimated.

Here, in the example of FIG. 4, in the communication of the method B, the position information of the user cannot be estimated by the communication method, and the communication CN2 does not include the GPS information. Therefore, the estimation device 100 is based on the information about the communication CN2. , The user's position information in communication CN2 cannot be estimated. Therefore, the estimation device 100 uses the area A estimated in the date and time DA immediately before the date and time DB as the user's position information in the communication CN2.

For example, the acquisition unit 131 acquires various information from the user information storage unit 121, the communication information storage unit 122, the advertisement information storage unit 123, and the access point information storage unit 124. For example, the acquisition unit 131 acquires information related to one communication from the terminal device 10 used by the user. In addition, the acquisition unit 131 acquires an advertisement request from the terminal device 10 as information related to one communication. For example, the acquisition unit 131 acquires an advertisement request from the terminal device 10 used by the user U1.

(Judgment unit 132)
The determination unit 132 estimates various information. For example, the determination unit 132 makes a determination based on information related to one communication. For example, the determination unit 132 determines whether or not the determination based on the information regarding one communication satisfies a predetermined condition. For example, the determination unit 132 determines whether or not one communication is performed by the first communication method. For example, the determination unit 132 determines whether or not one communication is performed by a predetermined wireless LAN communication method.

In the example of FIG. 1, the determination unit 132 makes a determination based on the information regarding the advertisement request (one communication). In this case, the determination unit 132 determines that the predetermined condition is satisfied because the communication for which the advertisement request is acquired from the terminal device 10-1 is Wi-Fi communication.

In the example of FIG. 1, the determination unit 132 makes a determination based on the information regarding the advertisement request (one communication). As described above, when the terminal device 10 communicates by the communication method according to the communication standard of the terminal device 10 such as 3G communication, the estimation device 100 estimates the user's position information in the communication from the information related to the communication method. Can't. Therefore, the determination unit 132 determines that the communication for which the advertisement request is acquired from the terminal device 10-2 is 3G communication and therefore does not satisfy the predetermined condition.

(Estimation unit 133)
The estimation unit 133 estimates various information. For example, when the determination based on the information related to one communication by the determination unit 132 does not satisfy the predetermined condition, the estimation unit 133 is the position information different from the position information estimated based on the information related to one communication, and is a terminal device. Other position information estimated based on the information about other communication acquired from 10 is used as the user's position information in one communication. For example, when the determination by the determination unit 132 based on the information related to one communication does not satisfy a predetermined condition, the estimation unit 133 obtains other position information having higher accuracy than the position information estimated based on the information related to one communication. , The user's location information in one communication.

For example, when the determination based on the information on one communication by the determination unit 132 does not satisfy the predetermined condition, the estimation unit 133 estimates based on the information on other communication acquired from the terminal device 10 prior to the one communication. The location information based on the history information of the location information of is used as the location information of the user in one communication. For example, the estimation unit 133 uses the position information estimated based on the user's behavior pattern estimated from the history information of other position information as the user's position information in one communication.

For example, the estimation unit 133 uses the position information estimated based on the history information of other position information corresponding to the date and time when one communication is performed as the user's position information in one communication. For example, the estimation unit 133 uses the position information estimated based on the history information of other position information corresponding to the time zone in which one communication is performed as the user's position information in one communication. For example, the estimation unit 133 uses the position information estimated based on the history information of the other position information corresponding to the day of the week when one communication is performed as the user's position information in one communication.

For example, the estimation unit 133 is history information of other position information corresponding to the date and time when one communication was performed, and the weight is heavier as the weight is closer to the date and time when one communication is performed. The position information estimated based on the information is used as the user's position information in one communication. For example, the estimation unit 133 uses the weight value that increases as the date and time when one communication is performed and the position information estimated based on the frequency of each position information as the user's position information in one communication.

For example, the estimation unit 133 uses the position information estimated based on the frequency of each region in the history information of other position information corresponding to the date and time when one communication is performed as the user's position information in one communication. For example, the estimation unit 133 uses the location information based on the most frequent area in the history information of other location information corresponding to the date and time when one communication is performed as the user's location information in one communication.

For example, when the determination unit 132 determines that one communication is performed by a second communication method different from the first communication method, the estimation unit 133 corresponds to the communication by the first communication method. Estimate the user's location information in one communication based on the location information of. For example, when the determination unit 132 determines that communication has been performed by the communication standard of the terminal device 10 different from the predetermined wireless LAN, the estimation unit 133 has other position information in which communication has been performed by the predetermined wireless LAN. Based on, the user's position information in one communication is estimated. The estimation device 100 estimates the area where the terminal device 10-1 (that is, the user U1) requesting the advertisement is located.

In the example of FIG. 1, the estimation unit 133 assumes that a predetermined condition is satisfied because the communication obtained from the terminal device 10-1 is Wi-Fi communication, and the user U1 is based on the information included in the advertisement request. The area where is located is estimated to be area A. For example, the estimation unit 133 estimates the area where the terminal device 10-1 (that is, the user U1) requesting the advertisement is located. For example, the estimation unit 133 estimates the area where the user U1 is located as the area A based on the information indicating that the access point AP11 stored in the access point information storage unit 124 is installed in the area A.

In the example of FIG. 1, the estimation unit 133 assumes that the communication for which the advertisement request is acquired from the terminal device 10-2 is 3G communication and therefore does not satisfy the predetermined condition, and based on the information other than the information included in the advertisement request. Estimate the user's location information in the communication. For example, the estimation unit 133 estimates the area where the terminal device 10-2 (that is, the user U1) requesting the advertisement is located. For example, the estimation unit 133 estimates the user's position information in the communication from the information related to the communication method based on the history information stored in the user information storage unit 121. In the example of FIG. 1, the estimation unit 133 estimates that the user U1 is likely to be located in the area D at 9:00 pm on Saturday night based on the history information stored in the user information storage unit 121.

(Decision unit 134)
The determination unit 134 determines various information. For example, the determination unit 134 determines an advertisement to be delivered to the terminal device 10 used by the user. For example, the determination unit 134 determines the advertisement to be delivered to the terminal device 10 based on the user's position information in one communication estimated by the estimation unit 133. For example, the determination unit 134 delivers to the terminal device 10 an advertisement related to the user's position information in one communication estimated by the estimation unit 133. For example, the determination unit 134 determines the advertisement according to the area where the user is located. For example, the determination unit 134 determines the advertisement according to the area where the user is located and the target area attached to each advertisement.

For example, the determination unit 134 determines the advertisement to be delivered to the terminal device 10-1 based on the user's area estimated by the estimation unit 133. In the example of FIG. 1, since the estimation device 100 estimates that the user U1 is located in the area A, among the advertisements stored in the advertisement information storage unit 123, the advertisement whose target area is the "area A" is the terminal device 10-. Determined as an advertisement to be delivered to 1. For example, the determination unit 134 determines the advertisement A whose target area is the "region A" as an advertisement to be delivered to the terminal device 10-1.

Further, in the example of FIG. 1, the determination unit 134 uses the terminal device 10- based on the time zone when the user U1 requests the advertisement, which is 9:00 pm on Saturday, and the history information stored in the user information storage unit 121. Determine the advertisement to be delivered to 2. For example, the determination unit 134 determines, among the advertisements stored in the advertisement information storage unit 123, an advertisement whose target area is "region D" as an advertisement to be delivered to the terminal device 10-2.

(Distribution unit 135)
The distribution unit 135 transmits various information to an external information processing device. For example, the distribution unit 135 distributes the advertisement to the terminal device 10 used by the user based on the user's position information in one communication estimated by the estimation unit 133. For example, the distribution unit 135 distributes an advertisement related to the user's position information in one communication estimated by the estimation unit 133 to the terminal device 10 used by the user. For example, the distribution unit 135 distributes the advertisement determined by the determination unit 134 to the terminal device 10 used by the user. In the example of FIG. 1, the distribution unit 135 distributes the advertisement A to the terminal device 10-1. Further, in the example of FIG. 1, the distribution unit 135 distributes the advertisement D to the terminal device 10-2.

[3. Overwrite location information]
As described above, in the case of a communication method based on the communication standard of the terminal device 10 such as 3G or 4G, the estimation accuracy of the user's position information based on the position of the base station (base station BS11 or the like in FIG. 1) is in units of several km. Information related to communication such as 3G and 4G cannot be used for regional estimation if information indicating a position such as GPS information is not included. Therefore, the estimation device 100 estimates the user's position information in the communication based on the information related to the other communication.

For example, when the estimation device 100 cannot estimate the user's position information in one communication based on the information related to one communication, the estimation device 100 can be used for other communication in which communication by wireless LAN is performed or information in other communication including GPS information. Based on this, the user's location information in one communication is estimated. The estimation of the position information by the estimation device 100 regarding this point will be described with reference to FIG. 7. FIG. 7 is a diagram showing an example of overwriting the position information according to the embodiment. In the example of FIG. 7, communication between the terminal device 10 used by the user A and the estimation device 100 is shown as an example. In the example of FIG. 7, for the sake of simplicity, the information communicated between the terminal device 10 used by the user A and the estimation device 100 does not include the GPS information of the terminal device 10. And.

In the example of FIG. 7, as shown in the request list LT11, it is assumed that four requests RQ1 to RQ4 are transmitted from the terminal device 10 used by the user A to the estimation device 100. That is, in the example of FIG. 7, as shown in the request list LT11, four communications corresponding to each of the four requests RQ1 to RQ4 are performed between the estimation device 100 and the terminal device 10 used by the user A. It shall be. Further, the requests RQ1 to RQ4 may be various requests such as an advertisement request and a content request for the estimation device 100. In the example of FIG. 7, for the sake of simplicity, it is assumed that the communication between the terminal device 10 and the estimation device 100 used by the user A is only the communication corresponding to the four requests RQ1 to RQ4. To do.

For example, the request RQ1 represented by “Req_1” in FIG. 7 is a communication performed by a communication method according to a communication standard of a 3G or 4G terminal device 10. Further, for example, the request RQ2 shown by “Req_2” in FIG. 7 is a communication performed by a Wi-Fi communication method, which is a communication method using a predetermined wireless LAN. Further, for example, the request RQ3 indicated by "Req_3" and the request RQ4 indicated by "Req_4" in FIG. 7 are communications performed by a communication method according to the communication standard of the 3G or 4G terminal device 10. That is, the estimation device 100 can estimate only the user's position information in the communication of the request RQ2 based on the information related to the communication of the request RQ2. Note that "Area_1" shown in FIG. 7 may be information indicating a predetermined area such as "Region A" or "Region B", or may be information on latitude / longitude, an address, or the like.

Therefore, when the position information of each communication is estimated without using the position information based on other communication, the information is as shown in the request information RL11 (step S30). Specifically, as shown in the request information RL11 in FIG. 7, only the position information of the user in the communication of the request RQ2 is estimated to be "Area_1", and the user in the communication of the other requests RQ1, RQ3, RQ4. The position information of is "Unknown", that is, unknown. In this case, as shown in the request information RL11 in FIG. 7, only the position information corresponding to the communication of the request RQ2 is "○", that is, the information is available, and the position information other than the position information corresponding to the communication of the request RQ2 is "x". That is, there is no information.

On the other hand, when the estimation device 100 estimates the position information of each communication using the position information based on other communication, the information is as shown in the request information RL12 (step S31). Specifically, as shown in the request information RL12 in FIG. 7, the estimation device 100 determines the position of the user in the communication of the request RQ2 based on the installation information of the Wi-Fi access point which is the communication method in the request RQ2. The information is presumed to be "Area_1".

Further, the estimation device 100 estimates the user's position information in the communication of other requests RQ1, RQ3, RQ4 for which the user's position information is unknown as the user's position information "Area_1" in the communication of the request RQ2. In the example of FIG. 7, the estimation device 100 overwrites the user's position information "Unknown" in the communication of the request RQ3 with the user's position information "Area_1" in the communication of the request RQ2 (step S31-1). Further, in the example of FIG. 7, the estimation device 100 overwrites the user's position information "Unknown" in the communication of the request RQ4 with the user's position information "Area_1" in the communication of the request RQ2 (step S31-2). The estimation device 100 may overwrite the user's position information "Unknown" in the communication of the request RQ4 with the user's position information "Area_1" in the communication of the request RQ3.

In this way, when the estimation device 100 estimates the position information of each communication using the position information based on other communication, as shown in the request information RL12 in FIG. 7, in the communication of the requests RQ2, RQ3, and RQ4. The user's location information is estimated to be "Area_1". In this case, as shown in the request information RL12 in FIG. 7, the position information corresponding to the communication of the request RQ2, RQ3, RQ4 is "○", that is, the information exists, and only the position information corresponding to the communication of the request RQ1 is available. , "X", that is, no information. Note that FIG. 7 shows a case where the estimation process is performed only for the communication of the request RQ3 and RQ4 after the communication of the request RQ2, but the estimation device 100 is in the communication of the request RQ1 before the request RQ2. The user's location information may also be the user's location information "Area_1" in the communication of the request RQ2.

Further, the estimation device 100 may include the overwritten information as described above in the history information. As a result, the estimation device 100 can increase the amount of history information by the overwrite process as described above even when the information is insufficient.

In the example of FIG. 1, the estimation device 100 acquires an advertisement request from the terminal device 10-1 used by the user U1 as information regarding one communication.

Then, the estimation device 100 makes a determination based on the information related to one communication (step S102). When the determination based on the information related to one communication satisfies a predetermined condition (step S102: No), the estimation device 100 estimates the user's position information based on the information related to one communication (step S103). In the example of FIG. 1, the estimation device 100 satisfies a predetermined condition because the communication for which the advertisement request is acquired from the terminal device 10-1 is Wi-Fi communication, and the access point stored in the access point information storage unit 124. Based on the information indicating that the AP11 is installed in the area A, the area where the user U1 is located is estimated as the area A.

On the other hand, when the determination based on the information related to one communication does not satisfy the predetermined condition (step S102: Yes), the estimation device 100 estimates the user's position information based on the history information (step S104). In the example of FIG. 1, the estimation device 100 is based on the history information stored in the user information storage unit 121, assuming that the communication obtained from the terminal device 10-2 is 3G communication and therefore does not satisfy a predetermined condition. The user's position information in the communication is estimated.

After that, the estimation device 100 determines the advertisement based on the estimated position information (step S105). In the example shown in FIG. 1, the estimation device 100 determines the advertisement A whose target area is the "region A" as an advertisement to be delivered to the terminal device 10-1. Further, in the example shown in FIG. 1, the estimation device 100 estimates that the user U1 is located in the area D, and among the advertisements stored in the advertisement information storage unit 123, the terminal uses the advertisement whose target area is the "area D". It is determined as an advertisement to be delivered to the device 10-2.

After that, the estimation device 100 delivers the determined advertisement to the terminal device 10 (step S106). In the example shown in FIG. 1, the estimation device 100 delivers the advertisement A to the terminal device 10-1. Further, in the example shown in FIG. 1, the estimation device 100 delivers the advertisement D to the terminal device 10-2.
