1 is a configuration diagram of a content providing system according to an example.

The server 100 may provide content to a plurality of user terminals 110, 120, 130. For example, the content may include an online game provided to a user in real time, a social network service (SNS), and the like, and is not limited to the described embodiments. Users 111, 121, and 122 may use content through each of the user terminals 110, 120, and 130. Each of the user terminals 110, 120, and 130 may include a mobile terminal such as a smart phone, laptop, or tablet, and may include a non-mobile terminal such as a personal computer (PC). That is, the user terminals 110, 120, and 130 mean all devices that can be accessed online, and are not limited to the described embodiment.

The server 100 may be one of a plurality of servers providing the same content. Multiple servers may provide the same content, but each of the servers may represent the world within one separate content. For example, a user who receives content through a user account registered in the server 100 cannot receive content from another server through the user account. Accordingly, items in the content provided by the server 100 can be used only in the world within the server 100, and cannot be used in other servers. The server 100 or the administrator of the server 100 can control the value of the item by adjusting the type and number of items distributed in the world.

However, since the server 100 cannot arbitrarily dispose of the items held by the user, methods for inducing the user to dispose of the items owned by the user may be considered. For example, the server 100 may receive items to be disposed of from the user in exchange for providing the user with an item desired by the user, and discard the received items. Hereinafter, a method of strengthening the economic structure of the world in the server 100 by exchanging items with a user will be described in detail with reference to FIGS. 2 to 10.

2 shows the value of an item according to the quantity of the item according to an example.

According to the theory of economics in general, according to the law of supply and demand, as the supply of goods increases, the individual value of the goods decreases. This theory can be applied similarly to the world in online games. As the number of items distributed in the server increases, the value 200 of the corresponding item decreases. When the value of the item 200 increases due to the small amount of the circulation of the item, the server 100 may issue an additional item to lower the value 200 of the item. However, when the value of the item 200 is lowered due to an increase in the circulation amount of the item, it is difficult to adjust the value 200 of the item because the user's own item cannot be disposed of arbitrarily. In the following, a method of allowing a user to dispose of an item himself is described in detail with reference to FIGS. 3 to 10.

3 is a configuration diagram of a server according to an embodiment.

The server 300 includes a communication unit 310, a processor 320, and a memory 330. For example, the server 300 may be the server 100 described above with reference to FIG. 1.

The communication unit 310 is connected to the processor 320 and the memory 330 to transmit and receive data. The communication unit 310 may be connected to another external device to transmit and receive data. Hereinafter, the expression “transmit / transmit” “A” may indicate transmission / reception of “information or data representing A”.

The communication unit 310 may be implemented as circuitry in the server 300. For example, the communication unit 310 may include an internal bus and an external bus. As another example, the communication unit 310 may be an element connecting the server 300 and an external device. The communication unit 310 may be an interface. The communication unit 310 may receive data from an external device and transmit data to the processor 320 and the memory 330.

The processor 320 processes data received by the communication unit 310 and data stored in the memory 330. The "processor" may be a data processing device implemented in hardware having circuits having a physical structure for performing desired operations. For example, desired operations may include code or instructions included in a program. For example, the data processing device implemented in hardware includes a microprocessor, a central processing unit, a processor core, a multi-core processor, and a multiprocessor. , ASIC (Application-Specific Integrated Circuit), FPGA (Field Programmable Gate Array).

The processor 320 executes computer readable code (eg, software) stored in the memory (eg, the memory 330) and instructions caused by the processor 320.

The memory 330 stores data received by the communication unit 310 and data processed by the processor 320. For example, the memory 330 may store a program (or application, software). The stored program may be a set of syntaxes coded so that a user can exchange items and executable by the processor 320.

According to one aspect, the memory 330 may include one or more volatile memory, non-volatile memory and random access memory (RAM), flash memory, hard disk drive, and optical disk drive.

The memory 330 stores a set of instructions (eg, software) that operates the server 300. The instruction set for operating the server 300 is executed by the processor 320.

The communication unit 310, the processor 320, and the memory 330 will be described in detail with reference to FIGS. 4 to 10 below.

4 is a flowchart of an item exchange method according to an embodiment.

The following steps 410 to 470 may be performed by the server 300 described above with reference to FIG. 3.

In step 410, the server 300 receives the exchange quantity of the target item from the user terminal. The server 300 identifies a user with a user account. The target item may include different items having a plurality of types. Hereinafter, the user means a user identified as a user account.

In step 420, the server 300 calculates the basic value of the target item in the server 300. The basic value means the individual value of the target item. For example, the basic value may be calculated based on the total quantity of target items that are distributed within the server 300. As another example, the base value can be calculated based on the rating of the target item. A method of calculating the basic value of the target item is described in detail with reference to FIGS. 5 to 9 below.

In step 430, the server 300 calculates the exchange value based on the basic value of the target item and the exchange quantity of the target item. The exchange value may be the total value of items that the user intends to dispose. The method of calculating the exchange value is determined in detail with reference to FIG. 10 below.

In step 440, the server 300 determines a reward item corresponding to the exchange value. For example, the reward item may be an item having a high basic value of the item due to a small amount of distribution in the server 300. Reward items may be determined to lower the basic value. As another example, the reward item may be determined based on all items held by the user. When the user holds the first set item, the second set item included in the same set as the first set item may be determined as a reward item. As another example, the reward item may be an item provided based on probability.

In step 450, the server 300 outputs the reward item to the user terminal. The user may check the output reward item, increase the quantity of the target item if it is not the desired reward item, or add another item as the target item. When the quantity of the target item is changed or an additional target item is added, the above-described steps 410 to 450 may be performed again. Depending on the recalculated exchange value, the reward item can be changed.

In step 460, the server 300 receives the exchange request from the user terminal.

In step 470, the server 300 issues the reward item to the user, and discards the target item by the received quantity. By disposing of the target item as many times as the user has, the distribution quantity of the target item in the server 300 is reduced. The basic value of the target item may be increased by decreasing the distribution quantity of the target item.

5 illustrates items held by a plurality of users in a server according to an example.

Items distributed in the world 500 in the content provided by the server 300 are shown. For example, the world 500 may include a first user, a second user, and a third user. The first user has a first inventory 510, a second user has a second inventory 520, and a third user has a third inventory 530. The items held by each of the users are stored in the inventory 510 to 530.

The first user holds three first items (a) and two second items (b), and the second user holds one first item (a) and three second items (b) The third user has one first item (a), one second items (b) and one third items (c).

A method of calculating the basic value of the target item based on the illustrated world 500 will be described in detail with reference to FIGS. 6 to 9 below.

6 is a flowchart of a method of calculating a basic value of a target item according to an example.

According to an embodiment, the basic value of the target item may be calculated according to the quantity of the target item compared to the quantity of all items distributed in the server 300. Step 420 described above for the above embodiment includes steps 610 to 630 below.

In step 610, the server 300 calculates an inventory value for all items held by the user.

For example, one item has the same individual value, regardless of the item's rank or rarity, and the inventory value can be calculated based on the total quantity of items. Inventory value is proportional to the total number of items held by the user. In the embodiment of FIG. 5, if the individual value of the item is 1, the first user's first inventory value is 6, the second user's second inventory value is 4, and the third user's third inventory value is 3 . Since the total number of items distributed in the world 500 is 13, the world inventory value for the world 500 may be 13. The global inventory value is equal to the sum of the inventory values of the individual users.

As another example, each item has a different individual value according to the grade or rarity of the item, and the inventory value may be calculated based on the total number of items. In the above-described embodiment, since only the weights for the items are changed, description of the more detailed embodiment is omitted.

In step 620, the server 300 calculates the total number of target items held by reference users in the server 300. For example, reference users may be all users in server 300. As another example, reference users may be active users among all users in the server 300. The active user may be a user accessing the server 300 within a preset period. That is, active users may be users excluding sleeping users among all users.

 In the embodiment of FIG. 5, when the target item is the first item (a), the total quantity of the target item is 5, and when the target item is the second item (b), the total quantity of the target item is 7, and the target item In the case of the third item (c), the total number of target items is one.

In step 630, the server 300 calculates the basic value of the target item based on the inventory value and the total quantity of the target item. The basic value of the target item can be calculated by [Equation 1] below.

[Equation 1]

는 사용자(i)가 선택한 타겟 아이템(j)의 기본 가치이고,

는 사용자들의 인벤토리 가치들의 합(즉, 세계 인벤토리 가치)이며,

는 서버(300) 내의 타겟 아이템(j)의 전체 수량이다.In [Equation 1],

Is the basic value of the target item j selected by the user i,

Is the sum of users' inventory values (i.e., global inventory values),

Is the total quantity of the target item j in the server 300.

In the embodiment of FIG. 5, the basic value of the first item (a) is calculated as 2.6, the basic value of the second item (b) is calculated as 13/7, and the basic value of the third item (c) is 13 Is calculated as

7 is a flowchart of a method of calculating a basic value of a target item according to another example.

According to another embodiment, the basic value of the target item may be calculated according to the grade of the target item. Step 420 described above for the above embodiment includes steps 710 to 720 below.

In step 710, the server 300 determines the target grade of the target item. The target grade may be preset in consideration of performance and rarity of the target item. In the embodiment of FIG. 5, the first item (a) may be rated C, the second item (b) may be rated C, and the third item (c) may be preset to A rating.

In step 720, the server 300 determines the basic value of the target item according to the target class. The higher the target rating, the higher the basic value of the target item can be determined. A method of determining the basic value of the target item according to the target class will be described in detail with reference to FIG. 8 below.

8 is a flowchart of a method for determining a basic value according to a grade of a target item according to an example.

Step 720 described above with reference to FIG. 7 may include the following steps 810 to 840.

In step 810, the server 300 determines items having a target rating among all items held by the user. In the embodiment of FIG. 5, when the target item is the first item (a), the target class may be determined as the C class, and the first item (a) and the second item (b) having the C class may be determined.

In step 820, the server 300 calculates the first value based on the determined items. The first value is proportional to the number of items determined. For example, if all grades have a value of 1, the first value for grade C is calculated as 12, the first value for grade B is calculated as 0, and the first value for grade A is 1 Is calculated. As another example, if the C class has a value of 1, the B class has a value of 2, and the A class has a value of 3, the first value for the C class is calculated as 12, and the first for the B class The value is calculated as 0, and the first value for class A is calculated as 3.

In step 830, the server 300 calculates the total quantity of target items held by reference users in the server 300. In the embodiment of FIG. 5, when the target item is the first item (a), the total quantity of the target item is 5, and when the target item is the second item (b), the total quantity of the target item is 7, and the target item In the case of the third item (c), the total number of target items is one.

In step 840, the server 300 calculates a basic value based on the first value of the target class and the total quantity of the target item. For example, the basic value is calculated based on [Equation 2].

[Equation 2]

는 사용자(i)가 선택한 타겟 아이템(j)의 기본 가치이고,

는 서버(300) 내의 타겟 아이템(j)의 등급에 대한 제1 가치이며,

는 서버(300) 내의 타겟 아이템(j)의 전체 수량이다.In [Equation 2],

Is the basic value of the target item j selected by the user i,

Is the first value for the rating of the target item j in the server 300,

Is the total quantity of the target item j in the server 300.

For example, if the first value for class C is 12, the first value for class B is 0, and the first value for class A is 1, the basic value of the first item (a) is 2.4 Calculated, the basic value of the second item (b) is calculated as 12/7, and the basic value of the third item (c) is calculated as 1.

9 is a flowchart of a method for determining a basic value based on calculated basic values and preset values according to an example.

According to one aspect, the following step 910 may be further performed. After step 840 is performed, step 910 is illustrated as being performed, it is apparent that it can be performed even after step 630 is performed.

In step 910, the server 300 determines whether the calculated basic value for the target item is within a range of preset values. The first value as the lowest value and the second value as the highest value may be set. The first value and the second value may be set differently according to the grade of the target item. For example, in the C class, the first value is set to 1, the second value is set to 3, in the B class, the first value is set to 3, the second value is set to 4, and in the A class, the first value is set to 4, The value of 2 can be set to 5.

In step 920, if the basic value calculated for the target item does not exist within a range of preset values, the server 300 changes the basic value to a preset value. For example, when the calculated base value for the target item of class A is 1, the default value may be changed to a preset maximum value of 5 for class A.

10 is a flowchart of a method for calculating an exchange value based on a basic value and an exchange quantity according to an example.

According to one aspect, the above-described step 430 may include the following steps 1010 to 1030.

In step 1010, the server 300 calculates the initial exchange value based on the base value and the exchange quantity. For example, the initial exchange value can be calculated in proportion to the exchange quantity.

In step 1020, the server 300 determines a discount rate based on the exchange quantity. For example, the discount rate may be determined differently depending on the interval of the exchange quantity. The discount rate for 11 to 20 may be greater than the discount rate for 1 to 10. As another example, a discount rate for each of the target items may be determined. The discount rate for the first target item, the discount rate for the second target item, and the discount rate for the nth target item may be respectively determined. The discount rate should be determined such that the final exchange value for n pieces is less than the final exchange value for n + 1 pieces.

The discount rate can be understood as a fee for exchanging items. For example, the discount rate may be subtracting a preset value from an initial exchange value regardless of the exchange quantity.

In step 440 described above, the reward item may be determined based on the determined discount rate. For example, the higher the discount rate, the higher the reward item may be determined.

In step 1030, the server 300 calculates the exchange value based on the initial exchange value and the discount rate. The calculated exchange value may be the final exchange value.
