  The server device 130 is a device that provides various services to the mobile terminal 110 and the information processing device 120 via the line 140. The server device 130 includes a user information database (hereinafter, “database” is abbreviated as DB) 131 for performing user authentication when providing various services. In addition, the server device 130 has a participation information DB 132 for registering the price of a specific product input by a user who uses the campaign service. In this embodiment, a user who uses the campaign service inputs the price of a specific product is referred to as “participate in a campaign”.

The server device 130 is installed with a sales application 133 that provides a mail order service to the user. Note that the sales application 133 may be provided through a web browser of the information processing apparatus 120 instead of being installed in the server apparatus 130.
When the server apparatus 130 executes the sales application 133, the server apparatus 130 can provide a mail order service and a campaign service to the mobile terminal 110 and the information processing apparatus 120.

<2. Hardware configuration of server device>
Next, the hardware configuration of the server apparatus 130 will be described. FIG. 2 is a diagram illustrating a hardware configuration of the server apparatus 130.

  As illustrated in FIG. 2, the server device 130 includes a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, and a storage unit 204. Further, an input / output unit 205 and a communication unit 206 are provided. Note that each unit of the server device 130 is connected to each other via the bus 207.

  The CPU 201 is a computer that executes various programs (for example, sales application 133) stored in the storage unit 204.

  The ROM 202 is a nonvolatile memory. The ROM 202 stores various programs, data, and the like necessary for the CPU 201 to execute various programs stored in the storage unit 204. Specifically, a boot program such as BIOS (Basic Input / Output System) or EFI (Extensible Firmware Interface) is stored.

  The RAM 203 is a main storage device such as a DRAM (Dynamic Random Access Memory) or an SRAM (Static Random Access Memory). The RAM 203 functions as a work area that is expanded when various programs are executed by the CPU 201.

The communication unit 206 communicates with the mobile terminal 110 or the information processing device 120 via the line 140.

<3. Overview of the campaign service and how to determine the winners>
Next, an overview of the campaign service provided by the server device 130 and an overview of the winner determination method will be described.

  First, an outline of the campaign service provided by the server device 130 will be described. As described above, the server apparatus 130 provides a mail order service for selling products and a campaign service to the users of the mobile terminal 110 and the information processing apparatus 120.

In the case of the campaign service in the present embodiment, the sales price of the specific product is determined based on the price input by the user participating in the campaign. Here, it is assumed that the user inputs the price based on the following rules.
A user who can participate in the campaign is a user in which the purchase application 111 or 121 is installed in the mobile terminal 110 or the information processing apparatus 120 and the user information is registered in the user information DB 131 of the server apparatus 130.
The price that a user can enter for a specific product is only once during the campaign period.
-Once entered, the price cannot be changed.
-The price can be entered in units of 1 yen, and can be entered in a range from a predetermined lower limit value (for example, 1 yen) to an upper limit value (a value determined based on the normal price of a specific product). .

  Of the prices input by the user based on such rules, the sales price actually determined is the price input by the winner determined after the end of the campaign period. In other words, only the winner can purchase a specific product at the price entered by himself. Here, a method for determining a winner determined after the campaign period ends will be described.

  Hereinafter, the price input by the user is referred to as “entry price” to distinguish it from the actually determined sales price.

  FIG. 3 is a diagram for explaining a determination method for determining a winner in the mail order system 100. In FIG. 3, the horizontal axis represents the entry price (yen) input by each user, and is managed in units of one yen in this embodiment. In the example of FIG. 3, the lower limit value of the entry price that can be input by the user = 1 yen and the upper limit value = 10000 yen. The vertical axis indicates the number of users who input each entry price (referred to as “entry number”).

  As shown in FIG. 3, in the case of product name: A, a plurality of users input the same entry price for each entry price on the horizontal axis. For example, the number of users who entered the entry price = 1 yen is 100. On the other hand, the number of users who input entry price = 4912 yen is only one (user A). Also, the number of users who have entered the entry price = 4919 yen is only one (user B).

  In the mail order system 100, the number of users is totaled for each entry price input by the user, and an entry price with only one user is extracted. Then, the minimum entry price among the extracted entry prices is determined as the actual sales price of the specific product (product name: A). Also, the user who has entered the minimum entry price (user A) is determined as the winner. In other words, in the example of FIG. 3, the winner is the user A and the selling price is 4912 yen (the product with the product name: A is sold only to the user A at the selling price of 4912 yen).

  Thus, in the case of the mail order system 100, since only one winner is determined, an expensive product can be set as the specific product. As a result, it is possible to provide a campaign service that is attractive to the user and highly effective in attracting customers.

  Further, as in the prior art, the winner is not determined by simple lottery or application order, but based on the entry price entered by the user himself / herself. For this reason, a user's expectation with respect to winning can be improved, and the range of the customer attraction effect can be expanded.

  Further, the winner is not determined based on the numerical value (entry price) itself input by the user, but is determined based on the number of users who input the numerical value (entry price). Is more gameable. As a result, it can be expected that the user's willingness to participate in the campaign is stimulated and the number of accesses to the target service and the access frequency are improved.

  As described above, according to the mail order system 100 according to the present embodiment, more effective sales promotion activities can be provided in the mail order service.

<4. Functional configuration of server device>
Next, the functional configuration of the server device 130 will be described. FIG. 4 is a diagram illustrating a functional configuration of the server device 130. In the server apparatus 130, the CPU 201 can provide the mail order service and the campaign service by executing the sales application 133. Here, the function for mainly providing the campaign service will be described. .

  As illustrated in FIG. 4, the server device 130 includes an authentication unit 401, a user interface control unit 402, an entry management unit 403, an entry result analysis unit 404, and a winner management unit 405 as functions for providing a campaign service. . Note that the user information DB 131 and the participation information DB 132 are stored in the storage unit 204, for example.

  The authentication unit 401 performs user authentication when the server device 130 provides a mail order service. The authentication unit 401 performs user authentication based on user information stored in the user information DB 131.

  FIG. 5 is a diagram illustrating an example of user information (user information of the user of the mobile terminal 110) stored in the user information DB 131. As shown in FIG. 5, the user information 500 includes “user ID of purchase application”, “telephone number”, and “mail address” as information items. In order to increase confidentiality, the user ID may be hashed using a hash function and stored in the user information DB 131.

  It is assumed that the user of the mobile terminal 110 inputs the user information 500 when installing the purchase application 111 for receiving the mail order service. Thereby, the user information 500 of the user having the purchase application 111 is registered in the user information DB 131. In addition, the user information is not only used by the mail order service alone, but user information already registered in other instant messaging services and social networking services may be used. In that case, using the application for the instant messaging service or social networking service installed on the mobile terminal 110 used by the user, authentication for using the registered user information for the mail order service (so-called so-called) "App authentication") must be performed. When application authentication is used, the authentication process is performed not by the server device 130 but by a server device that provides the instant messaging service or social networking service.

  Similarly, the user of the information processing apparatus 120 registers user information when installing the purchase application 121.

  Returning to the description of FIG. The user interface control unit 402 controls the user interface displayed on the mobile terminal 110 of the user who receives the mail order service (including the campaign service).

  The entry management unit 403 operates during the campaign period, and manages users participating in the campaign and entry prices input by the user. Information for identifying a user participating in the campaign and an entry price input by the user are stored as participation information in the participation information DB 132.

  FIG. 6 is a diagram illustrating an example of participation information stored in the participation information DB 132. As shown in FIG. 6, the participation information 600 is managed for each product, and includes “input date / time”, “user ID”, and “entry price” as information items. The “input date / time” stores the date / time when the user inputs the entry price. The “user ID” stores the user ID registered in the user information 500 as information for identifying the user who entered the entry price. The user ID may be hashed using a hash function and stored in the participation information DB 132 in order to increase confidentiality. The “entry price” stores the entry price input by the user.

  Returning again to the description of FIG. The entry result analysis unit 404 operates after the end of the campaign period, and determines the winner and sales price of the specific product by counting the participation information stored in the participation information DB 132.

  The winner management unit 405 notifies the winner determined by the entry result analysis unit 404 and can access an access destination (for example, a purchase page) for performing a procedure for purchasing a specific product. Grant access rights to

<5. Flow of sales process in mail order system>
Next, the flow of the sales process in the mail order system 100 will be described with reference to FIGS. FIG. 7 is a sequence diagram showing the flow of sales processing in the mail order system 100.

  When the user 700 performs an operation (access operation) for receiving provision of mail order service on the mobile terminal 110 (step S701), the mobile terminal 110 transmits an access request to the server device 130 (step S702). .

  The access request transmitted to the server device 130 is sent to the authentication unit 401, and user authentication is performed in the authentication unit 401 (step S703). Note that user authentication may be performed by the above-described application authentication. If it is determined that the user authentication is successful as a result of the user authentication in the authentication unit 401, the user interface control unit 402 is notified of the success (step S704).

  Upon receiving the notification, the user interface control unit 402 controls the mobile terminal 110 to display a sales screen for providing mail order service (step S705). FIG. 8 is a diagram showing an example of the sales screen 800. As shown in FIG. 8, in the product display area 810 of the sales screen 800, products sold by the seller in the mail order service are displayed.

  Among these, the product of “product name: A” is a specific product that is the target of the campaign service. For this reason, by selecting the icon 811 indicating the product, the user can request the use of the campaign service for the specific product.

  When the user performs an operation for requesting the use of the campaign service (step S706), the portable terminal 110 transmits a request for using the campaign service to the server device 130 (step S707). When the user interface control unit 402 of the server device 130 receives a campaign service use request from the mobile terminal 110, the user interface control unit 402 controls the mobile terminal 110 to display a campaign service screen (step S708). FIG. 9 is a diagram illustrating an example of a campaign service screen displayed on the mobile terminal 110.

  As shown in FIG. 9, in the area 901 of the campaign service screen 900, it is clearly indicated that the product selected by the user is a specific product that is the target of the campaign service. In the area 901, the campaign period is specified.

  Furthermore, in the area 902 of the campaign service screen 900, the product name of the product selected by the user and the appearance photograph of the product are specified. Furthermore, a button 903 for requesting entry price entry is clearly displayed on the campaign service screen 900.

  In parallel with the control that the user interface control unit 402 displays the campaign service screen 900 on the mobile terminal 110, each unit of the server device 130 executes a winner determination process (step S709). Details of the winner determination process will be described later.

  When the user presses the button 903 on the campaign service screen 900 displayed on the mobile terminal 110 (step S710), the mobile terminal 110 transmits an entry price input request to the server device 130 ( Step S711).

  Upon receiving the entry price input request, the server device 130 controls the mobile terminal 110 to display an entry screen. FIG. 10 is a diagram illustrating an example of an entry screen displayed on the mobile terminal 110.

  In FIG. 10A, an input area 1001 is an area for the user to input an entry price. A button 1002 is a button for transmitting entry information including the entry price input in the input area 1001 to the server device 130.

  When the user inputs an entry price for purchasing the product name: A and presses the button 1002 (step S713), the portable terminal 110 transmits entry information to the server device 130 (step S714). The entry information transmitted from the mobile terminal 110 to the server device 130 includes the entry price input by the user, the telephone number of the mobile terminal 110, the user ID of the purchase application, and the like.

  When a pressing operation on the button 1002 is performed, as shown in FIG. 10B, the input area 1001 of the entry screen 1000 is locked, and entry of an entry price by the user is prohibited. Further, the button 1002 is also locked, and it is prohibited to repeatedly transmit entry information.

  As described above, in the mail order system 100 according to the present embodiment, the user inputs the entry price only once for the specific product (product name: A), and changes the entry price after transmitting the entry information. Can not do it. That is, in the mail order system 100 according to the present embodiment, the entry price can be input only once for one specific product during the campaign period.

  Returning to the description of FIG. After the entry information is transmitted from the mobile terminal 110 to the server device 130, the server device 130 receives entry information from a plurality of users until the campaign period ends by repeating the same processing. When the campaign period ends, the winner is determined, and a winning notification is transmitted to the mobile terminal 110 (step S715).

<6. Winner decision process>
Next, the flow of the winner determination process (step S709 in FIG. 7) will be described. FIG. 11 is a flowchart showing the flow of the winner determination process. Here, the winner determination process for the product name: A will be described.

  In step S1101, the entry management unit 403 determines whether a campaign period has started. If it is determined that the campaign period has not yet started, the system waits until the campaign period starts.

  On the other hand, if it is determined that the campaign period has started, the process proceeds to step S1102. In step S1102, the entry management unit 403 determines whether an entry price input request has been received. If it is determined in step S1102 that an entry price input request has not been received, the process advances to step S1109.

  On the other hand, if it is determined in step S1102 that an entry price input request has been received, the process advances to step S1103. In step S1103, the user interface control unit 402 controls to display the entry screen 1000 on the requesting mobile terminal 110 that has requested entry of the entry price.

  In step S1104, the entry management unit 403 acquires entry information transmitted from the mobile terminal 110. In step S1105, the entry management unit 403 determines whether or not the entry price included in the entry information transmitted from the mobile terminal 110 is not less than a lower limit value (for example, 1 yen) and not more than an upper limit value (for example, 10,000 yen). Determine.

  If it is determined in step S1105 that the entry price is less than the lower limit value or exceeds the upper limit value, the process proceeds to step S1107. In step S <b> 1107, the user interface control unit 402 controls the mobile terminal 110 to display an error message.

  FIG. 12 is a diagram illustrating an example of an error message displayed on the mobile terminal 110. As shown in FIG. 12A, when 0 yen is input in the input area 1001 of the entry screen 1000 and the button 1002 is pressed, an error message 1201 is displayed as shown in FIG. If the OK button 1202 is pressed in the error message 1201, the error message 1201 disappears and the screen returns to the entry screen 1000 shown in FIG.

  On the other hand, if it is determined in step S1105 that the entry price is not less than the lower limit and not more than the upper limit, the process proceeds to step S1106. In step S1106, the entry management unit 403 registers the input date and time, the hash ID based on the telephone number, and the entry price in the participation information DB 132.

  In step S1108, the user interface control unit 402 instructs the mobile terminal 110 that has transmitted the entry information to change the entry screen 1000 to a screen indicating that the entry information has been acquired. As a result, the entry screen 1000 of the portable terminal 110 is changed to the screen shown in FIG.

  In step S1109, the entry management unit 403 determines whether or not the campaign period has ended. If it is determined that the campaign period has not ended, the process returns to step S1102.

  On the other hand, if the entry management unit 403 determines in step S1109 that the campaign period has ended, the process proceeds to step S1110. In step S1110, the entry result analysis unit 404 performs a tabulation process on the participation information 600 stored in the participation information DB 132. Details of the aggregation process will be described later.

  In step S <b> 1111, the user interface control unit 402 controls to display the aggregation result in step S <b> 1110 on the mobile terminal 110. Furthermore, the winner management unit 405 notifies the winner's mobile terminal 110 of the winner. The winning notification includes a message indicating winning, a sales price of a specific product, and a URL (Uniform Resource Locator) for accessing a purchase page selling the specific product.

  FIG. 13 is a diagram illustrating an example of a summary result screen displayed on the mobile terminal 110. As illustrated in FIG. 13, the total result screen 1300 includes an area 1301 for displaying the product name of the specific product that is the target of the campaign service, and an area 1302 indicating the total result.

  In the area 1302 indicating the counting result, the entry price of the user of the mobile terminal 110 and the number of users who input the same entry price as the entry price are displayed. Also, the entry price for each entry number, such as the entry price entered by the winner, the entry price for one entry, the entry price for two entry, the entry price for three entry, etc. Is displayed.

  Further, an entry price with the largest number of entries and the highest entry price and the lowest entry price among the entered entry prices are displayed in an area 1302 indicating the total result.

  Returning to the description of FIG. In step S <b> 1112, the winner management unit 405 gives the winner the access authority that enables access to the purchase page of the specific product. Thereby, the user (winner) who has received the winning notification can access the URL of the purchase page and perform a purchase procedure for the specific product.

<7. Flow of counting process>
Next, the flow of the aggregation process (step S1110 in FIG. 11) will be described. FIG. 14 is a flowchart showing a detailed flow of the aggregation process in the server device 130. In step S1401, the entry result analysis unit 404 analyzes the participation information 600 and calculates the number of users who input each entry price.

  In step S <b> 1402, the entry result analysis unit 404 extracts an entry price with the entry number “1”.

  In step S1403, the entry result analysis unit 404 extracts the minimum entry price from the entry prices extracted in step S1402.

  In step S1404, the entry result analysis unit 404 identifies the user who has input the minimum entry price extracted in step S1403.

  In step S1405, the entry result analysis unit 404 determines that the user specified in step S1404 is a winner, determines the entry price input by the winner as a sales price, and returns to step S1111 (FIG. 11).

<8. Summary>
As is apparent from the above description, the mail-order sales system 100 according to the present embodiment has a configuration in which only one user who can purchase a specific product as a campaign service target is determined as a winner.

  Thereby, since it is possible to set an expensive product as a specific product, it is possible to provide a campaign service that is attractive to the user and has a high effect of attracting customers.

  Further, in the mail order system 100 according to the present embodiment, the winner is determined based on the entry price entered by the user, not the configuration in which the winner is determined by simple lottery or the order of application as in the past. The configuration.

  Thereby, the user's expectation for winning can be improved, and the range of the effect of attracting customers can be expanded.

  In the mail order system 100 according to the present embodiment, the winner is not determined based on the numerical value (entry price) itself input by the user, but based on the number of users who input the numerical value (entry price). The winner is determined.

  As a result, it is expected that the game performance in the method for determining the winner increases, the user's willingness to participate in the campaign is stimulated, and the number of accesses to the target service and the access frequency are improved.

  As a result, the mail order system 100 according to the present embodiment can provide effective sales promotion activities in the mail order service.

[Second Embodiment]
In the first embodiment, the entry price with one entry is extracted, but the present invention is not limited to this. For example, an entry price with the smallest number of entries may be extracted considering that there may be no entry price with one entry.

  FIG. 15 is a flowchart showing a detailed flow of the aggregation processing of the server device 130 in the present embodiment. The same steps as those in the aggregation process shown in FIG. 14 are denoted by the same reference numerals, and description thereof is omitted here. Below, it demonstrates centering on difference with FIG.

  As shown in FIG. 15, in step S1501, the entry result analysis unit 404 extracts the entry price with the smallest number of entries.

  In step S1502, the entry result analysis unit 404 determines whether the number of entries with the minimum entry price extracted in step S1403 is one. If it is determined in step S1502 that the number of entries is one, the process proceeds to step S1404.

  On the other hand, if it is determined in step S1502 that the number of entries is not one, the process proceeds to step S1503. In step S1503, the entry result analysis unit 404 identifies the user who entered the entry price earliest among the users who entered the minimum entry price extracted in step S1403.

  In step S1504, the entry result analysis unit 404 determines the user specified in step S1503 or the user specified in step S1404 as a winner, and determines the entry price input by the winner as a sales price.

  As described above, according to the mail order system 100 according to the present embodiment, even if there is no entry price with one entry, the winner and the sales price can be determined.

[Third Embodiment]
In the first embodiment, the user can input the entry price only once during the campaign period (the number of times that the user can enter the entry price). However, the present invention is not limited to this. For example, the entry price may be input by the number of times (number of entries) preset for each user.

  The number of entries is set for each user in the user information 500, and the user interface control unit 402 displays the entry screen at the entry price input request source (step S1103). 500 is referred to. Thereby, it can control to display the screen for entry according to the number of entries.

  FIG. 16 is a diagram showing an example of an entry screen having a number of input areas corresponding to the number of entries. In the example of FIG. 16A, the number of entries is set to 3, and input areas 1601 to 1603 are displayed as input areas for the user to enter entry prices.

  As a result, the user can input entry prices in each of the input areas 1601 to 1603 (that is, three entry prices can be input). In the example of FIG. 16B, an entry price is input to the input area 1601 and the input area 1602, and the button 1002 is pressed. For this reason, the input area 1601 and the input area 1602 are locked, and the user is in a state where entry of entry prices to the input area 1601 and the input area 1602 is prohibited. On the other hand, the entry price has not yet been entered in the input area 1603, and the user can enter the entry price in the input area 1603.

  In this way, by setting the number of entries for each user, the user can input the entry price for a predetermined number of times. Even if the number of entries increases, the entry price once entered cannot be changed.

  Therefore, in order to input an entry price different from the entry price that has already been input, the user needs to increase the number of entries.

Here, the number of entries preset for each user is, for example,
・ When a new user who receives mail order service is introduced and the user registers new user information,
・ If you subscribe to a specific page,
・ If you follow a specific account,
It is assumed that it is configured to increase.
