Description

  The present invention relates to an information distribution method, an information distribution system, and an information distribution program, and in particular, an information distribution method capable of distributing effective and highly effective advertising information to a communication terminal by using position information, and the like. About.

  In recent years, wireless communication terminals for performing wireless communication have become widespread. In particular, mobile phones equipped with functions as telephones are becoming more popular due to the convenience of being able to make and receive calls regardless of location and time, as well as higher functionality, lower prices, and wider call areas. The momentum is remarkable. In particular, in recent mobile phones, those having an information transmission / reception function such as e-mail and those capable of transmitting / receiving location information using GPS (Global Positioning System) have become mainstream. Here, the terminal means a terminal device.

  On the other hand, many recent mobile phones are equipped with an Internet connection function as well as a personal computer (hereinafter referred to as a PC). A PC or mobile phone having this Internet connection function is generally equipped with a web browser, and can access various Internet sites via the Internet.

  For example, it is possible to obtain various information related to a search keyword by accessing a search site where a keyword search is possible by a search engine and inputting the search keyword. For example, the news information of the day can be obtained by accessing a news distribution site operated and managed by a newspaper company.

  As described above, with the spread of access to Internet sites using communication terminals such as PCs and mobile phones, the Internet sites have attracted attention and are widely used as new advertising media. For example, an advertisement display frame is provided on a part of the site page of the above-mentioned search site or news distribution site, and advertisement information is posted in the frame, so that it is viewed by many Internet users and a high advertisement effect is obtained. It has been.

  Recently, advertising information that is more useful to users of Internet sites is selectively displayed to obtain a higher advertising effect. For example, based on a search keyword input to a search site, advertisement information highly relevant to the keyword is displayed together with the search result (for example, refer to Patent Documents 1 to 5). Thereby, the advertisement information related to the keyword that the user is highly interested in is selectively displayed, and the user is also highly interested in the advertisement information. As a result, the displayed advertisement information exhibits a high appeal and advertisement effect for the user.

  In addition, a service for accurately measuring the position of a mobile phone or its user by using a position measurement system such as GPS is also provided. According to this, even if it is difficult to grasp the surrounding situation in an unknown place, for example, the surrounding situation can be roughly grasped by acquiring the position information of the user with the mobile phone (for example, patent See references 6-8.)

  Based on the location information on the communication terminal side and the location information on the advertiser side that provides the advertisement information, the distance between the two is calculated, and the priority (ranking) is given to the advertisement information according to the distance to the communication terminal Advertisement information is also provided (see, for example, Patent Documents 9 and 10). According to these, advertisement information close to the location of the communication terminal is preferentially provided. It is even more convenient for you.

JP 2003-196509 A Special table 2003-501729 gazette JP 2005-533327 A JP 2005-537591 A Japanese translation of PCT publication No. 2006-5000699 JP 2001-306567 A JP 2003-045452 A JP 2004-310524 A International Publication No. 2006/12997 International Publication No. 2007/010611

  However, when an advertiser provides advertisement information, there are cases where it is desired to limit the provision range (distribution area). In other words, there are cases where the advertiser wants to set the distribution of advertisements in a distribution area within a predetermined range from the specific point as a base point, and not to distribute the advertisement outside the distribution area. By setting in this way, it is possible to achieve both of obtaining a high advertising effect within the distribution area and reducing unnecessary advertisement distribution outside the distribution area.

  In addition, distribution may be performed with a distribution probability corresponding to a bid price for each advertisement information. The bid price is an amount determined by the advertiser and the advertisement information distributor, for example, a price paid by the advertiser to the advertisement information distributor for each advertisement information distribution. That is, advertisement information with a higher bid price is distributed with a higher probability, and advertisement information with a lower bid price is distributed with a lower probability. As a result, even advertisement information with an extremely low bid price is distributed with a certain low distribution probability, which causes a problem that unfairness occurs between advertisement information.

  Therefore, in order to ensure fairness between advertising information, it is automatically determined whether the bid price is above or below a certain boundary value, and the distribution of advertising information is set according to the determination result There is a need to devise a method for distributing advertisement information. In addition, it is more preferable that an optimum boundary value can be automatically set in order to improve the profit of the advertising information distributor in setting the constant value.

  The present invention has been made in view of the above circumstances, and can automatically ensure fairness between information (for example, advertisement information), and also automatically ensure profitability of the information distributor. It is an exemplary problem to provide a new and useful information delivery method, an information delivery system, and an information delivery program that can be different from conventional ones.

  In order to solve the above problem, an information distribution method as an exemplary aspect of the present invention is an information distribution method for distributing information to a communication terminal capable of specifying position information, and is related to information distribution. Compare the price threshold and the bid price with the distribution area setting step that accepts the area setting, the bid price setting step that accepts the bid price setting related to information, the threshold setting step that sets the price threshold based on the bid price As a result, when the bid price is equal to or higher than the price threshold, it is determined that the information can be distributed, and when the bid price is less than the price threshold, it is determined that the information cannot be distributed, and the information determined to be distributeable And an information distribution step of not distributing information determined not to be distributed.

  “Information” is typically advertising information by an advertiser, but is not limited thereto. The information includes various information by the information distributor (person who desires information distribution).

  “Communication terminal” refers to all terminal devices capable of information communication, and includes, for example, mobile phones, personal computers (including notebook PCs and desktop PCs), PDAs, smartphones, pagers, and the like. Further, “communication” includes wireless communication and wired communication, including communication by digital signal, communication by analog signal, radio wave, sound wave, light (infrared ray, etc.). “Specification of position information” is typically measurement of a position using GPS, but is not limited to its own position. For example, a specific position is specified (clicked) on a map displayed on the screen. Including location by location.

  The “bid price” is a unit price set for information distribution. It is a consideration negotiated between the distributor and the information distributor, and is substantially synonymous with a so-called information distribution fee, typically an advertising fee. When the distributor sets a bid price of 30 yen for certain information, for example, 30 yen consideration is paid to the information distributor for each distribution of the information.

  Since the distribution area can be set, the range in which information distribution is desired can be limited. In addition, since it is possible to automatically determine that information that is less than the price threshold (boundary value) cannot be distributed, it is possible to stop distributing information with an extremely low bid price. Information with extremely low bid prices can be prevented from being distributed with a certain probability, and as a result, fairness between information can be ensured.

  In the information distribution step, when a plurality of pieces of information are determined to be distributable, a plurality of pieces of information may be distributed under equal conditions.

  Even when information determined to be distributable has different bid prices for each information, they can be distributed under equal conditions. “Equal condition” includes, for example, distribution with an equal distribution probability, and distribution so as to achieve a uniform display mode (same display size, same highlighting, etc.) on the communication terminal. Further, even when the bid price for each advertisement information is different, the billing of the advertisement fee for the advertisement distribution may be equal (that is, the same fee), and the same fee may be a price threshold. Since information bid at a bid price equal to or higher than the price threshold is distributed under equal conditions, fairness between information can be further ensured.

  In the distribution area setting step, it is possible to accept the setting of a plurality of distribution areas for one information, and in the bid price setting step, it is possible to accept the setting of a plurality of bid prices for one information. Good.

  If there is an area where you want to distribute one piece of information and an area where you want to distribute it separately, set a high bid price for the area you want to distribute, and if possible, set a lower bid price for the area you want to distribute. It becomes possible. In addition to ensuring reliable information distribution for areas that must be distributed, bid prices can be suppressed for areas that are to be distributed, if possible.

  In the threshold setting step, when one or a plurality of pieces of information are selected from the highest bid prices, the selected minimum bid price that is the lowest of the bid prices related to the selected information, and the distribution areas that are respectively related to the selected information Estimated earnings based on either the total area area or the total of the unselected maximum bid price, which is the highest bid price related to information that was not selected, and the total area area. The price threshold value may be calculated to be equal to or higher than the non-selected highest bid price when the expected profit value is maximized.

  The price threshold can be set automatically. In addition, the automatically set price threshold value can be set to an optimum value that balances high profitability and the number of pieces of distribution information. In other words, as much information as possible can be distributed, and the information distributor can secure as much advertising fee income as possible. It is possible to automatically set a price threshold that is highly beneficial for both the distributor and the information distributor.

  Here, it is preferable that the price threshold is set to be higher by the minimum currency unit (for example, 1 yen, 1 dollar, 1 euro, 1 Chinese yuan) than the unselected highest bid price when the expected profit value is maximized. Further, it is preferable that the price threshold is lower than the selected minimum bid price.

  Further, it is preferable that the price threshold is equal to or higher than the non-selected highest bid price when the expected profit value is “maximum”. Of course, when the price threshold is set based on these conditions, if the number of selected information becomes very small or the total area of the distribution area becomes very small, efficient information distribution is possible. May not be able to be performed.

  In such a case, the price threshold value may be determined in consideration of other conditions in addition to the above conditions. Other conditions in this case include, for example, “select at least the number of information to be selected” or “select information so that the total area is not less than the minimum XX”. is there. In addition, even if all of these conditions cannot be satisfied, so that one of the conditions is satisfied and the other conditions are close to being satisfied (for example, the conditions for the number of information and the total area area are satisfied). However, it is desirable to set a price threshold so that the expected profit value is close to the maximum.

  Here, the following method is also conceivable as a price threshold setting method, that is, in the threshold setting step, an expected profit value is calculated by integrating the unselected highest bid price and the total area area, and the price threshold value is set as the expected profit value. It may be higher than the non-selected maximum bid price when the value is maximized and less than the selected minimum bid price.

  Further, in the threshold setting step, an expected profit value is calculated by integrating the selected minimum bid price and the total area area, and the price threshold is equal to or greater than the selected minimum bid price when the expected profit value is maximized and is selected. It may be less than the low bid price, which is the next lowest price after the minimum bid price.

  In the threshold setting step, different coefficients may be integrated for each distribution area related to the selected information, and the integrated values may be summed to obtain a total area area.

  In the distribution of information, the importance may be different for each distribution area. In such a case, weighting (light weight distribution) can be performed for each distribution area according to the importance of the distribution area. For example, a large coefficient can be set for distribution areas including areas with large populations and busy areas where many people gather, and a small coefficient can be set for distribution areas including areas with small populations, suburbs, and mountainous areas. . The degree of influence on the total area area of a distribution area including a region with many people (generally, the effect of information distribution is high) can be increased.

  An information distribution system as another exemplary aspect of the present invention is an information distribution system that distributes information to a communication terminal capable of specifying position information, and receives a setting of a distribution area related to the information As a result of comparing the price threshold with the bid price, the bid price setting unit that accepts the setting of the bid price related to the information, the threshold setting unit that sets the price threshold based on the bid price, A determination unit that determines that the information can be distributed when it is equal to or greater than the threshold, and that determines that the information cannot be distributed when the bid price is less than the price threshold, and the position information within the distribution area that is determined to be distributable And an information distribution unit that does not distribute information determined to be undeliverable.

  Since the distribution area can be set, the range in which information distribution is desired can be limited. In addition, since it is possible to automatically determine that information that is less than the price threshold (boundary value) cannot be distributed, it is possible to stop distributing information with an extremely low bid price. Information with extremely low bid prices can be prevented from being distributed with a certain probability, and as a result, fairness between information can be ensured.

  An information distribution program as still another exemplary aspect of the present invention is an information distribution program for distributing information to a communication terminal capable of specifying position information, and sets a distribution area related to information to a computer. The distribution area setting unit that receives the bid price, the bid price setting unit that receives the setting of the bid price related to the information, the threshold value setting unit that sets the price threshold based on the bid price, the result of comparing the price threshold and the bid price, It is determined that the information can be distributed when the price is equal to or higher than the price threshold, and the determination unit that determines that the information cannot be distributed when the bid price is less than the price threshold, and the information that is determined to be capable of being distributed within the distribution area The position information is distributed toward the specified communication terminal, and functions as an information distribution unit that does not distribute information determined to be undistributable.

  Since the distribution area can be set, the range in which information distribution is desired can be limited. In addition, since it is possible to automatically determine that information that is less than the price threshold (boundary value) cannot be distributed, it is possible to stop distributing information with an extremely low bid price. Information with extremely low bid prices can be prevented from being distributed with a certain probability, and as a result, fairness between information can be ensured.

  Further problems or other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, since a distribution area can be set, a range in which information distribution is desired can be limited. In addition, it is possible to automatically determine whether the bid price is equal to or greater than a certain boundary value (price threshold), and automatically determine whether information can be distributed according to the determination result. Information that is less than the price threshold (boundary value) can be automatically made undeliverable, so that unfairness between information due to the extremely low bid price being distributed can be eliminated. The fairness between information can be automatically secured, and the profitability of the information distributor can be automatically secured.

[Embodiment 1]
Hereinafter, an advertisement information distribution method (information distribution method) according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram showing the overall configuration of an advertisement system S that realizes this advertisement information distribution method. This advertisement system S includes an advertisement distribution server (information distribution apparatus, computer) 4, a base station G, a mobile phone (communication terminal) 2, a content distribution server 8, and the Internet W.

  The advertisement distribution server 4 includes a distribution area setting unit, a bid price setting unit, a threshold setting unit, a determination unit, and an advertisement information distribution unit (information distribution unit), and is appropriately selected from a plurality of pieces of advertisement information (information). The advertisement information is extracted and distributed to the mobile phone 2. A detailed description of the configuration and operation of the advertisement distribution server 4 will be described later.

  In the first embodiment, the mobile phone 2 is described as an example of the communication terminal. However, the communication terminal may be any terminal device capable of transmitting / receiving information to / from the advertisement distribution server 4 by wireless communication or wired communication. A PC (personal computer) connected to the advertisement distribution server 4 via W may be used.

  In addition, in the “specification of position information by the communication terminal”, not only when the current position of the mobile phone 2 itself is measured using the GPS function of the mobile phone 2 but also on the map displayed on the PC screen. This includes the case of selecting (clicking) a specific position with. The position specified in these cases is referred to as terminal position, and the position information is referred to as terminal position information. Of course, the communication terminal also includes a PDA, a smartphone, and the like.

  Here, “distributing advertisement information toward the mobile phone 2” means that the advertisement information is displayed on the display screen of the mobile phone 2 as a result, and the information path is not limited. For example, in the first embodiment, a configuration in which advertisement information is transmitted from the advertisement distribution server 4 to the content distribution server 8 when the mobile phone 2 accesses the content distribution server 8 will be described. The advertisement information is combined with the content in the content distribution server 8 and transmitted from the content distribution server 8 to the mobile phone 2.

  However, for example, a configuration in which advertisement information is directly distributed from the advertisement distribution server 4 to the mobile phone 2 when the mobile phone 2 accesses the content distribution server 8 is also conceivable. The mobile phone 2 is provided with a combining program for combining the content received from the content distribution server 8 and the advertisement information received from the advertisement distribution server 4, and both are combined in the mobile phone 2 and displayed on the display screen. It is like that.

  In addition, the application software of the mobile phone 2 has an advertisement placement frame and an advertisement information receiving function, and the application software (without receiving the content from the content distribution server 8) with the activation of the application software May be configured to receive the advertisement information from the advertisement distribution server 4 and display it within the advertisement placement frame.

  The base station G is for performing wireless communication with the mobile phone 2. The base station G is configured to be connected to a telephone network (not shown) to realize a call by the mobile phone 2 and to be connected to the Internet W to realize an Internet connection using the mobile phone 2. Therefore, the information transmitted from the mobile phone 2 is received and transmitted to the advertisement distribution server 4 and the content distribution server 8 via the Internet W, and the information from the advertisement distribution server 4 and the content distribution server 8 is transmitted via the Internet W. And transmitting to the mobile phone 2. The mobile phone 2 also has a function of receiving position information and transmitting it to the advertisement distribution server 4.

  When a PC is used as the communication terminal instead of the mobile phone 2, the advertising system S does not need to have the base station G because the PC is connected to the Internet W directly or via a LAN.

  The mobile phone 2 has a call function and an Internet connection function. The mobile phone 2 is configured to be able to transmit and receive information to and from the advertisement distribution server 4 and the content distribution server 8 connected to the Internet W via the base station G. Moreover, it also has a GPS (Global Positioning System) function, and can acquire its own location information (terminal location information) using the GPS satellite 10. The terminal position information (position information of the second position) 2p is transmitted from the mobile phone 2 toward the base station G, or directly transmitted from the GPS satellite 10 toward the base station G. .

  FIG. 2 is an explanatory diagram showing a state in which the content 8 a transmitted from the content distribution server 8 is displayed on the display screen 2 a of the mobile phone 2. In the first embodiment, the content distribution server 8 is a keyword search site server, and the content 8a is a search page. In this content 8a, a search keyword input frame 8b, a search result display frame 8c, and an advertisement information display frame 8d are provided. When a search keyword is input to the search keyword input frame 8b, the search result is displayed in the search result display frame. 8c is displayed.

  When the content 8a is transmitted to the mobile phone 2 and displayed on the display screen 2a, the advertisement information is displayed in the advertisement information display frame 8d. This advertisement information is transmitted from the advertisement distribution server 4 to the content distribution server 8.

  As a specific information flow, when the mobile phone 2 accesses the content distribution server 8, the mobile phone 2 transmits a content request signal I1 to the content distribution server 8 via the base station G. Upon receiving the content request signal I1, the content distribution server 8 transmits an advertisement information request signal I2 to the advertisement distribution server 4. When receiving the advertisement information request signal I2, the advertisement distribution server 4 extracts one distribution advertisement information I3 to be distributed, and transmits the distribution advertisement information I3 to the content distribution server 8. Upon receiving the distribution advertisement information I3, the content distribution server 8 is configured to display the distribution advertisement information I3 in the advertisement information display frame 8d, and then transmits the content 8a to the mobile phone 2.

  The mobile phone 2 has a function of measuring terminal position information 2p as its own position information. The position information measuring function may be one that uses GPS satellites 10 for example, or may be one that measures positions using information transmission / reception performed with a plurality of base stations G. Good. It also has a function of transmitting the measured terminal location information 2p toward the base station G. The terminal position information 2p is transmitted to the advertisement distribution server 4 directly or via the content distribution server 8.

  In the first embodiment, the second position specified by the communication terminal is the location of the mobile phone 2, and the location information of the location is transmitted to the advertisement distribution server 4 as the terminal location information 2p. The However, for example, on the map information displayed on the screen of the PC as the communication terminal, the position selected by clicking with the mouse is set as the second position, or the position corresponding to the address information input from the keyboard on the PC is set to the second position. It can also be a position. Even in such a case, position information corresponding to these second positions is transmitted toward the advertisement distribution server 4.

  The content distribution server 8 is a server computer connected to the Internet W, and provides a search service using a search engine. The content distribution server 8 has a function of transmitting the content 8a to the mobile phone 2 that has transmitted the content request signal I1, and a search keyword input in the search keyword input frame 8b in the content 8a displayed on the display screen 2a. And a function for transmitting information to the mobile phone 2. Further, it has a function of transmitting the advertisement information request signal I2 to the advertisement distribution server 4, and a function of transmitting the received distribution advertisement information I3 together with the content 8a to the mobile phone 2.

  The advertisement distribution server (computer) 4 is a server computer for distributing advertisement information to the mobile phone 2 via the Internet W. The first embodiment is configured to transmit distribution advertisement information (distribution information) I3 to the mobile phone 2 via the content distribution server 8.

  FIG. 3 is a block diagram showing an outline of the internal configuration of the advertisement distribution server 4. The advertisement distribution server 4 includes a storage device 12, a CPU 14 as a main part of the computer, and a main memory 16. The storage device 12 is data storage means such as a hard disk, for example, and holds an advertisement information distribution program 18 therein.

  The advertisement information distribution program 18 includes a distribution area setting unit 19, a bid price setting unit 22, a threshold setting unit 23, a determination unit 24, and an advertisement information distribution unit (information distribution unit) 25. It is a program to make it function as. Each function of the CPU 14 exhibited by the advertisement information distribution program 18 will be described later.

  The storage device 12 also holds an advertisement database D1 therein. FIG. 4 is a data structure diagram showing an outline of the data structure of the advertisement database D1. The advertisement database D1 includes, as internal information, advertiser information (information distributor information) 26, advertisement information (information) 27, distribution area information 29, and bid price information 30, as shown in FIG. Each piece of information is constructed in association with each other. Here, the distribution area information 29 includes base point position information (position information of the first position) 31 and area size information 32.

  The advertiser information 26 is information on an individual or a corporation that desires to distribute the advertisement information 27. For example, the advertiser information 26 may include information such as an advertiser name, an advertiser location, and an advertiser contact information. In addition, the advertiser information 26 may be identification information for identifying an advertiser and another advertiser. In general, one advertiser information 26 is associated with one advertisement information 27. Of course, when an advertiser wants to distribute a plurality of advertisement information or to distribute advertisement information in a plurality of regions, one The advertiser information 26 and the plurality of advertisement information 27 are associated with each other.

  The advertisement information 27 is information including information on products sold by the advertiser and information provided by the advertiser, contact information of the advertiser, and the like, and is information that the advertiser desires distribution to the user. For example, the advertisement information 27 includes a banner advertisement having product image information, link information for guiding user access to an Internet site operated and managed by the advertiser, and the like. The advertisement information 27 is distributed as distribution advertisement information I3 toward the user's mobile phone 2 and displayed on the display screen 2a.

  The distribution area information 29 is information in a range where the advertiser wants to distribute the advertisement information 27, and is information set by the advertiser. For example, the distribution area information 29 includes base point position information (first position information) 31 and area size information 32.

  The base position information 31 is position information related to the base position (first position) specified by the advertiser. This base point position is a central position that the advertiser considers most important when distributing the advertisement information 27.

  The area size information 32 is information set by the advertiser. For example, in the first embodiment, the area size information 32 is set as distance information such as 100 m and 200 m. Thereby, a circular distribution area 35 centered on the base point 34 and having a radius set as the area size information 32 is conceptualized on the map information 4c (see FIG. 5). The distribution area 35 is a range where the advertiser desires distribution of the advertisement information 27 of the advertiser.

  Of course, the distribution area 35 need not be limited to a circular region. It may be a rectangular area using latitude and longitude information, or may be an area (generally an irregular shape) according to the administrative division.

  When the terminal position (second position) 2q corresponding to the terminal position information 2p of the mobile phone 2 is present in the distribution area 35, the advertisement information 27 can be distributed toward the mobile phone 2, and the terminal position The advertising information 27 is configured not to be distributed when 2q exists outside the distribution area 35.

  The bid price information 30 is also referred to as so-called advertising fee, and is information for indicating a consideration paid from an advertiser to an advertisement information distributor (information distributor) for advertisement distribution. The determination unit 24 determines whether the advertisement information 27 can be distributed or cannot be distributed depending on whether the bid price information 30 is high or low.

  In this advertising system S, an advertising fee is charged to the advertiser every time the advertising information 27 is distributed toward the mobile phone 2 (that is, every time it is displayed on the display screen 2a). Alternatively, the advertisement information 27 displayed on the display screen 2a may be clicked by the user and generated every time the detailed advertisement information of the link destination is browsed.

  Next, each function performed by the CPU 14 by the advertisement information distribution program 18 will be described.

  When the advertisement information distribution program 18 is activated, an input screen 4a is displayed on a display screen (not shown) of the advertisement distribution server 4 as shown in FIG. The input screen 4a is an input screen for various information for the advertiser to bid on the advertisement information 27 of the advertiser. In this input screen 4a, an address information input frame 4b and map information 4c are configured. By inputting address information or landmark information such as a station name in the address information input frame 4b, it corresponds to the input information. The position to be identified is specified as the base point 34. Further, the position on the map information 4c corresponding to the clicked position can also be specified as the base point 34 by clicking the specified position on the map information 4c with the mouse.

  When the advertiser specifies the position of the base point 34 related to his / her advertisement information 27 on the input screen 4a, the distribution area setting unit 19 receives and receives the base point position information 31 corresponding to the base point 34 in the advertisement database D1. It is supposed to be stored in. Note that a database (not shown) for associating the base point 34 with the base point position information 31 is stored in the storage device 12 of the advertisement distribution server 4.

  The input screen 4a also includes a radial distance input frame 4d, in which area size information 32 as distance information can be input. For example, if the area size information 32 of “100” is input in the radius distance input frame 4d, a circular area having a radius of 100 m with the base point 34 as the center is set as the distribution area 35.

  Instead of inputting the area size information 32 in the radial distance input frame 4d, the distribution area 35 can be set on the map information 4c by dragging the mouse from the base point 34 on the map information 4c. A distance corresponding to the scale on the map information 4 c between the position where the mouse button is released and the base point 34 is set as the area size information 32.

  When the advertiser sets distribution area information 29 (base position information 31, area size information 32) related to his / her advertisement information 27 on the input screen 4a, the distribution area setting unit 19 receives the distribution area information 29. And stored in the advertisement database D1.

  Although not described in the first embodiment, regional information may be input in addition to the distribution area information 29 (base point position information 31 and area size information 32). In this case, the regional information is information that is set by the advertiser and is information on a region where the advertiser wants to distribute the advertising information 27. For example, the regional information includes prefecture information such as Tokyo and Kanagawa prefectures, city information such as Yokohama city and Kawasaki city, and the like. In the storage device 12, these area information and administrative area information are associated with each other and stored as a database. The administrative area can be specified by inputting the regional information.

  The advertisement information 27 is distributed toward the mobile phone 2 existing in the administrative district specified by the regional information. In other words, in this case, the advertisement information 27 may be distributed to the mobile phone 2 that is in the administrative area specified by the regional information and that exists in the distribution area 35. Good.

  In the input screen 4a, a bid price input frame 4e is also set. The advertiser inputs bid price information 30 related to his / her advertisement information 27 to the bid price input frame 4e. The bid price information 30 is price information such as “25 yen” and “30 yen”, for example. When the advertiser sets the bid price information 30 on the input screen 4a, the bid price setting unit 22 receives the bid price information 30 and stores it in the advertisement database D1.

  Although the input of the advertisement information 27 is not particularly described, an input frame (not shown) for inputting the advertisement information 27 is set in the input screen 4a and may be input there. Further, the advertisement information 27 may be input on another input screen. In any case, the input advertisement information 27 is associated with the distribution area information 29 and the bid price information 30 and stored in the advertisement database D1. Even if the advertisement information 27 itself is not stored in the advertisement database D1, the association information may be stored in the advertisement database D1.

  The threshold setting unit 23 acquires the bid price information 30 from the advertisement database D1 and sets a price threshold based on the bid price information 30. The setting procedure will be described in detail below.

<Price threshold setting procedure>
In explaining the price threshold setting procedure by the threshold setting unit 23, a bid example as shown in FIG. 6 is assumed. FIG. 6 shows a situation in which a plurality of advertisers set bid price information 30 and distribution area information 29 for each advertisement information 27 (here, advertisement information A to E). Specifically, the bid information 30 of “90 yen”, “50 yen”, “30 yen”, “25 yen”, and “22 yen” is set for the advertisement information A to E, respectively. Each of the advertisement information A to E is in turn a distribution area having a radius of “100 m” centered on the base point a, a distribution area having a radius of “80 m” centering on the base point b, a distribution area having a radius of “200 m” centering on the base point c, A distribution area having a radius “50 m” centered on the base point d and a distribution area having a radius “30 m” centered on the base point e are set as the distribution area information 29. FIG. 7 shows an explanatory diagram of the setting procedure by the threshold setting unit based on this assumption example.

  When the threshold value is set by the threshold setting unit 23, only the advertising information in which the bid price information 30 is set higher than the price threshold is delivered, and the advertising information whose bid price information 30 is equal to or lower than the price threshold is Not delivered.

  Here, the distributed advertisement information is referred to as selected advertisement information 20, and the non-distributed advertisement information is referred to as non-selected advertisement information. The lowest bid price of the selected advertisement information 20 is called a selected lowest bid price, and the highest bid price of non-selected advertisement information is called a non-selected highest bid price.

  The threshold setting unit 23 arranges the advertisement information A to E in descending order of the bid price information 30. When the order is the order of advertisement information A, B, C, D, E, when the selected advertisement information 20 is only advertisement information A, when it is advertisement information A + advertisement information B, advertisement information A + advertisement information The case of B + advertisement information C, the case of advertisement information A + advertisement information B + advertisement information C + advertisement information D, and the case of advertisement information A + advertisement information B + advertisement information C + advertisement information D + advertisement information E are assumed. The threshold setting unit 23 calculates a non-selected highest bid price 36, a total area area 37, and an expected value (expected profit value) 38 in each case. FIG. 8 is a diagram showing the non-selected highest bid price 36, the total area area 37, and the expected value 38 set by the threshold setting unit 23.

  Here, the total area area 37 is a value corresponding to the total area of the distribution areas 35 set by each of the plurality of selected advertisement information 20. The actual area value is not necessarily required, and may be standardized by a predetermined coefficient while maintaining a relative ratio between the total area areas 37. For example, according to FIG. 8, the total area area 37 when the advertisement information A is the selected advertisement information 20 is “30”, and the total area area 37 when the advertisement information A + B is the selected advertisement information 20 is “45”. ". Here, when the distribution area 35 based on the advertisement information A and the distribution area 35 based on the advertisement information B partially overlap, the total area area 37 is deducted from the overlapping portion. In calculating the total area area 37, different coefficients may be accumulated for each distribution area 35. For example, if the resident population is different for each distribution area 35, the advertising effect may be different even in the same area. By integrating different coefficients for each distribution area 35, the difference can be corrected.

  The expected value 38 is an integrated value obtained by integrating the non-selected highest bid price 36 and the total area area 37 in each case. 8, for example, the expected value 38 when the advertisement information A is the selected advertisement information 20 is “50 yen” × “30 =“ 1500 yen ”, and the advertisement information A + B is the selected advertisement information 20. In this case, the expected value 38 is “30 yen” × “45 =“ 1350 yen ”.

  Thus, the threshold value setting unit 23 sequentially calculates the expected value 38 in each case as “1500 yen”, “1350 yen”, “2000 yen”, “1870 yen”, and “900 yen”. Here, the case where the expected value 38 is 2,000 yen (maximum in the present embodiment 1) is determined to be the case where the profit rate is the best, and the threshold setting unit 23 (advertising information) The price threshold is set to 26 yen, which is 1 yen (minimum currency unit) higher than the unselected maximum bid price 36 in the case where A + B + C is the selected advertisement information 20.

  Here, the price threshold may be set to an amount that is several yen higher (for example, 28 yen) than the unselected highest bid price when the advertisement information A + B + C is the selected advertisement information 20, and is 26 yen, which is 1 yen higher. It is not necessarily required to be set to. However, it is desirable that the price threshold is lower than the selected minimum bid price (that is, 30 yen). This is because when it is 30 yen or more, the expected value 38 decreases. Of course, it may be configured so that the lowering of the expected value 38 is recognized and set to be higher than the selected minimum bid price.

<Description of functions of determination unit 24 and advertisement information distribution unit 25>
When the threshold value setting unit 23 sets the price threshold value to “26 yen”, the determination unit 24 acquires the bid price information 30 of each advertisement information A to E from the advertisement database D1, and the price threshold value “26 yen” and the bid price information. Compare 30. Then, it is determined that the advertisement information (advertisement information A, B, C in FIG. 6) whose bid price information 30 is greater than or equal to the price threshold “26 yen” can be distributed, and the advertisement information whose bid price information 30 is less than the price threshold ( It is determined that the advertisement information D, E) in FIG.

  The advertisement information distribution unit 25 distributes the advertisement information 27 toward the mobile phone 2 based on the determination result by the determination unit 24. Specifically, the advertisement information A, B, C determined to be deliverable is delivered toward the mobile phone 2 existing in the delivery area 35.

  At this time, the advertisement information distribution unit 25 distributes the advertisement information A to C determined to be distributed with an equal distribution probability. That is, if the total number of distributions within a certain period of time toward a plurality of mobile phones 2 existing in the distribution area 35 is, for example, 300 times, each of the advertisement information A, B, C is distributed 100 times. Here, the bid price information 30 of the advertisement information A to C is different from “90 yen”, “50 yen”, and “30 yen”, respectively, but the advertiser is charged for each distribution. The advertising fee is set to 26 yen which is a price threshold for any advertising information A to C. Thereby, the unfairness between advertisement information is eliminated, and it can be set as a system with a big merit for both an advertiser and an advertisement distributor.

[Embodiment 2]
FIG. 9 is a conceptual diagram showing how the distribution area 35 is set in the advertisement system S that implements the advertisement information distribution method according to Embodiment 2 of the present invention. In this advertising system S, a plurality of distribution areas 35 a and 35 b can be set for one piece of advertising information 27. Different bid price information 30a and 30b are set for each of the distribution areas 35a and 35b. Therefore, the input screen 4a according to the second embodiment is configured as shown in FIG. 10, and a plurality of radial distance input frames 4d and a plurality of bid price input frames 4e are set.

  Accordingly, for example, bid price information 30a of “200 yen” is set for the distribution area 35a having the radius “50 m” centered on the base point 34, and “50” is set for the distribution area 35b having the radius “100 m” centering on the base point 34. The bid price information 30b of “yen” can be set.

  The distribution area 35a is an area that the advertiser thinks “want to reliably distribute the advertisement”. On the other hand, the distribution area 35b is an area that the advertiser considers “I want to distribute an advertisement if possible”. By setting different bid price information 30a and 30b in these distribution areas 35a and 35b, when the price threshold value is less than 50 yen, the advertisement information can be distributed to the large distribution area 35b. Further, even when the price threshold value is 50 yen or more (for example, 100 yen), the advertisement information can be distributed at least in the small distribution area 35a.
