Hereinafter, a method and a server for providing a dynamic item purchase service according to each embodiment of the present invention will be described with reference to the accompanying drawings.

In the following description, in order to clarify the understanding of the present invention, description of well-known technology for the features of the present invention will be omitted. The following embodiments are detailed description to help understand the present invention, and it should be understood that the present invention is not intended to limit the scope of the present invention. Accordingly, equivalent inventions performing the same functions as the present invention are also within the scope of the present invention.

In the following description, the same reference numerals denote the same components, and unnecessary redundant explanations and descriptions of known technologies will be omitted.

In the embodiments of the present invention, " communication ", " communication network ", and " network " The three terms refer to wired and wireless local area and wide area data transmission and reception networks capable of transmitting and receiving a file between a user terminal, a terminal of another user, and a download server.

In the following description, the term " game server " refers to a server computer to which users are connected and connected to use game contents. In the case of a game having a small capacity or a small number of users, a plurality of game programs can be operated in one game server. In addition, in the case of a game having a very large capacity or a large number of real-time connections, there may be one or more game servers for operating one game depending on the functions of the game.

In addition, middleware for the database and servers performing payment processing can be connected to the game server, but a description thereof will be omitted in the present invention.

In the present invention, the online game refers to game contents which are accessible to users by accessing the above-mentioned game server. Particularly, it means a game in which a plurality of users can simultaneously access and enjoy the game, and the level is raised through an act of acquiring experience while fostering a character by advancing a game. In addition, it means a game in which various types of items can be purchased in order to smoothly progress the game in the game.

An item here refers to all the data that can help the progress of the game and can be understood as an item in a game in general. For example, in a role-playing game, an item that allows a character to substitute for a user to obtain more experience value obtained when a monster is suppressed, an item that can change the appearance of a character, etc. correspond to an item can do.

In addition, in sports games, card items that can use the character, items that increase the character's stats for a certain period of time, items that restore the character's condition, and the character's ability to improve the game's stats while modifying the appearance As mentioned above in the game, such as giving items, all items that can be used by the character in the progress of the game, or that can be reflected on the game by the user on the web, will belong to the items in the present invention.

Also, in the present invention, the item may be rated at least one version and at least one rating. That is, even if an item of the same name, for example, the version of the item to suit the particular event, such as the 'Chuseok commemorative version', 'World Cup version', for example, the size and type of the effect of the item may vary . For example, a card item that can be used by a player in a sports game may be an item that can be used by default in the general version. In contrast, if a card item of the 'World Cup version' exists, The stats may have higher stats than the regular version.

In addition, there may be a rating of an item. In general, in an role playing game or a sports game, an effect of an item may be greatly increased through an action of calling the same item as 'enhancement' or 'smelting'. In general, role-playing games can be strengthened by using gems or reinforcing materials on items that a character can equip, and a grade change mark such as '+1' is added to the item's name.

Items with a higher grade have a greater effect than the items of the basic grade, so that the price is also greatly increased. In the present invention, the description of the version and the grade of the above-mentioned items will be equally applied in the following description.

In the present invention, the purchase of an item is connected to an online game or an item shop serviced on a game through a network using a terminal, a user selects an item registered in the item shop, and purchases game money equal to the price of the item. After paying, it means to register in the database of items owned by the user.

Therefore, the user can check the information of the item in the item shop, select the item he wants to purchase, check the price of the item, and purchase the item by paying the game money that he owns as a whole. When purchasing an item, at least one identical item may be purchased at the same time.

In general, the price of an item is fixed to all users except for special discount events. Also, whether or not an item can be purchased is usually controlled by level, race, or class. However, in the present invention, as described below, the availability and price of the item will vary depending on the user.

1 is a flowchart of a method for providing a dynamic item purchase service according to an embodiment of the present invention.

Referring to FIG. 1, in the method for providing a dynamic item purchase service according to an embodiment of the present invention, a server that provides a dynamic item purchase service first includes an item database so that a user can purchase an item shop by accessing the item shop. Receiving a purchase input for a purchase option item as an item including purchase authority information for purchasing the item, for the registered item (S10).

As mentioned above, the purchasing authority for the item in the conventional item shop has been set only for the level, race, occupation, etc. of the character, or only for meeting the conditions of the event during the special event item.

However, in the present invention, the right to purchase an item is sold as a purchase option item, which is another item, and the registered item can be purchased only when the purchase option item corresponding to the item to be purchased is held.

In the present invention, a registered item that can be purchased only by purchasing a purchase option item may be an item set by setting of a manager terminal among items available in a game.

Upon receiving a purchase input for a purchase option item, the server may provide the user with purchase authority information for purchasing an item corresponding to the purchase option item, and price change data for the item as information on which the price of the item is changed at a predetermined cycle. The step S20 of transmitting to the user terminal is performed.

Transmitting the purchase authority information and the price change data to the user terminal in step S20, after storing in the user's information in the game server or a separate storage space, the user purchases the item in the item shop, or the information about the price of the item Upon confirmation, it includes loading it into a user account or a user terminal. In addition, the server may store purchase authority information and price change data in a storage space of the server separately for each user.

The purchase authority information means authority information that can be included in the purchase option item and can purchase an item corresponding to the purchase option item. The purchase authority information may include information of an item corresponding to a purchase option item.

The price change data includes information in which the price of the item corresponding to the purchase option item is changed according to a predetermined period (for example, one day). The price change data includes the price information of the item in the period including when the user confirms it, the period from which the user purchased the purchase option item to the period when the user checks the price of the item. At least one of price change history information and price change history information from a time of registering an item to a period including a time point of checking a price of an item may be included. As mentioned below, in the present invention, the price change data includes different price changes according to the user, so that different price change data may be transmitted.

Thereafter, the server performs a step (S30) of receiving a purchase input for an item registered from the user terminal, and the server analyzes the information of the item for which the purchase input is received, and for the item corresponding to the purchase input in the user account. It is determined whether the user possesses the purchasing authority information, and when it is determined that the user has the purchasing authority information, when the purchase input is received from the price of the item included in the price change trend data of the item corresponding to the purchase input included in the user information Extracting the price of the item corresponding to the and subtracts it from the game money held by the user (S40).

When the step S30 is performed, the user may check the price of the item that currently has his purchasing authority information through a screen corresponding to the item shop or the user information confirmation menu. Since the price fluctuates periodically, the user can access the game from time to time to check how the price of the current item is.

Through this, when the user confirms that the price, which is considered appropriate, is set as the price for the item, the user may perform a purchase input for the item in response to step S30.

In operation S40, when the game money held by the user is less than the price of the item corresponding to the time at which the purchase input is received, information indicating that the purchase of the item has failed may be transmitted to the user terminal.

If the price is normally deducted by the step S40, the server performs a step (S50) of registering the item corresponding to the purchase input to the database of items held by the user.

In this way, the user must purchase a purchase option item corresponding to the item in order to purchase the item, and when purchasing the purchase option item, the user can check the price of the item in the period including the access point through the terminal. Since the price of the item fluctuates every predetermined period, the user may recognize that the price of the item fluctuate and purchase the item when the price is determined to be appropriate as the price of the item.

2 is a flowchart of a method for providing a dynamic item purchase service according to another embodiment of the present invention.

2 specifically illustrates the detailed flow of purchasing an item in the embodiment of FIG. 1.

Referring to FIG. 2, first, the server performs a step S30 of receiving a purchase input for a registered item from a user terminal.

Thereafter, the server analyzes the information of the user when receiving the purchase input, and determines whether the purchase authority information exists as an authority to purchase an item corresponding to the purchase input (S41).

Since the purchasing authority information is paid at the time of purchasing a purchase option item corresponding to the item to be purchased at step S41, step S41 is the same as determining whether the user has purchased the purchase option item.

If the purchase authority information normally exists, the step S43 of loading the above-mentioned price change data provided with the purchase authority information when purchasing the purchase option item from the user information is performed. The price change data may be stored in the user's information in the game server or in a storage space in the dynamic item purchase service providing server as mentioned above.

As mentioned above, the price change data may be set differently for each user. That is, different prices may be set for the same item in the current cycle according to the user holding the purchasing right information.

When the price change data is loaded, the server performs a step S44 of extracting a price corresponding to a purchase input receiving time, among prices of items corresponding to at least one purchase input that may be included in the price change data.

Before the step S44 is performed, the user can check the price of the current cycle of the item before performing the purchase input. That is, step S44 may be replaced by collecting price information of the item currently displayed on the user terminal.

When the price of the item is determined, the server subtracts the price of the extracted item from the game money held by the user, and registers the item in the database of the item held by the user (S51). Of course, if the price of the extracted item is larger than the game money held by the user, information indicating that the purchase of the item failed may be transmitted to the user terminal and the purchase of the item may be cancelled.

If it is determined in step S41 that the purchase authority information is not held, the server may perform step S42 of informing that the purchase of the item has failed because there is no purchase authority information in the user terminal.

3 illustrates the flow of receipt of a purchase input in accordance with each embodiment of the present invention. It will be appreciated that the following description of FIGS. 3 to 5 may apply to all of the flows mentioned in the description of FIGS. 1 and 2. In addition, portions overlapping with the description of FIGS. 1 and 2 will be omitted.

Referring to FIG. 3, first, the server performs a step S41 of determining whether a user has purchase authority information on a registered item corresponding to a purchase input through analysis of user information.

In this case, the purchase right to purchase the registered item in the present invention may be a right for which a valid period is determined, not a permanent right. That is, the user may purchase the item within a predetermined period when purchasing the purchase option item including the purchase right, and may be provided with price change data of the item.

Therefore, the user must purchase the item within the validity of the purchase authority, and the server determines that the user has given up the purchase authority of the item when the validity period has elapsed, and converts the effect of the purchase authority to off.

Therefore, even if the user holds the purchasing right, the server determines whether the validity period of the purchasing right information has elapsed (S45). According to a technical flow, step S45 may be omitted when the purchase right of the item is set to expire when the valid period elapses.

If the purchase right is not held or the validity period has elapsed, step S42 of FIG. 2 is performed, so that the server transmits information indicating that the purchase of the item has failed to the user terminal, and has the purchase right and the validity period is If not, the server normally proceeds to step S43 of Figure 2 to proceed to purchase the item.

4 is a flowchart illustrating a purchase option item purchase according to an embodiment of the present invention.

As mentioned in FIG. 3, the validity period is set in the purchase authority information included in the purchase option item for the item. In the present invention, the validity period may be adjusted by the selection of the user terminal when purchasing a purchase option item.

That is, referring to FIG. 4, the server first performs a step (S10) of receiving a purchase input for a purchase option item. At this time, the server performs a step (S11) of receiving a selection input for the valid period of the purchase authority information.

In step S11, the server first transmits at least one preset validity period to the user terminal, and receives a selection input for any one of the validity periods transmitted from the user terminal.

The at least one preset validity period may be the same for each purchase option item or may be set differently for each purchase option item. For example, the validity period of purchase authority that can be selected when purchasing all purchase option items is set to 7, 21, 35 days, etc., or one item is 7, 21, 35, etc., and the other item is 14, 28, 42, etc. Can be set.

When the server receives the selection input for the valid period from the user terminal through step S11, to perform the step (S21) of transmitting the purchase authority information having the selected valid period to the user terminal, that is, the storage space in which the user information is stored. do.

Having the selected validity period means that the effect is controlled on or off depending on whether the selected validity period has elapsed, or that it expires when the validity period has elapsed, depending on whether the validity period has elapsed.

When step S21 is performed, step S22 of performing total loss on price change data having a different change value for each user is performed. As mentioned above, the price change data is transmitted to the user terminal so that the price of the current cycle is set differently for each user even for the same item.

Purchase option items can be purchased by paying game money in the same manner as general items. Thus, purchasing the purchase option item naturally includes subtracting the price of the purchase option item from the game money held by the user.

At this time, since it is possible to set the validity period of the purchase authority information in the purchase option item, the price of the purchase option item may also be set differently according to the validity period of the purchase authority information. Accordingly, the value deducted from the game money held by the user may vary according to the validity period.

For example, even with the same purchase option item, the price of the purchase option item with a validity period of 7 days may be lower than that with a validity period of 14 days.

5 illustrates a flow in which the price of an item is changed according to each embodiment of the present invention.

The price of the item may change every predetermined period (for example, one day). In order to change the price of the item, the server first, when the predetermined period has elapsed, from the elapsed period, that is, the price P0 of the currently established item, the price fluctuation range d to be changed within a preset price change range (for example, 20% of the price of the item in the elapsed period (S23) to perform a random selection.

When the variation range (d) is selected, the server performs a step (S24) to randomly select (+,-) whether to raise or decrease the price from the price (P0) of the item in the elapsed period, and finally In operation S25, a price P1 of a new period, that is, a new period, may be determined through an equation (P1 = P0 ± d).

Thereafter, the server performs a step S26 of adding the price P1 of the determined new period item to the details of price change data managed for each user.

In step S26, the server may replace the price change data in a new cycle. That is, the price of the item of the elapsed period may be deleted, and only the price of the item of the new period may be stored.

Alternatively, the price of the item of the new period may be additionally stored in a space in which the prices of the item of the previous periods are stored in order to provide a user with a change in price.

Accordingly, the server displays or displays a screen for checking the price of the item, such as user information, the user terminal, or an item shop that can be checked by the user. The period in which the price of the item is changed may be transmitted from a period corresponding to a time point or a point in which the item is registered in the game server to a new period, that is, a period corresponding to the current point in time.

According to a function, the purchase input receiving unit 14 and the item purchasing control unit 15 may be stored as separate servers to implement another embodiment of the present invention.

The purchase authority information generator 11 transmits purchase authority information for purchasing an item corresponding to the purchase option item upon receiving a purchase input for the purchase option item from the user terminal 20, and changes the price. When the data generation unit 13 receives a signal indicating that the purchase authority information is sent from the purchase option item issuing unit 11, the data generation unit 13 transmits the price of the item determined for the current period to the purchase option item management unit 12.

At this time, the purchase authority information generation unit 11 transmits a menu for selecting a valid period of the purchase authority information among preset valid periods to the user terminal 20 when a purchase input of a purchase option item is received, and inputs a selection for this. Received to set the validity period of the purchase authority information, and accordingly according to whether the selected validity period has elapsed to generate and transmit the purchase authority information whose effect is on-off controlled.

The price change data generation unit 13 generates and transmits different price change data for each user as shown in FIG. 5. Accordingly, the user can purchase the same item at different prices at the same time.

The purchase option item manager 12 manages purchase authority information and price change data for each user and transmits the same to the user terminal 20 upon request from the user terminal 20.

The purchase input receiver 14 receives the purchase input of the item from the user terminal 20.

The item purchase control unit 15 may purchase, from among at least one price included in the price change data corresponding to the item, when the user effectively holds the purchase authority information of the item corresponding to the purchase input when the purchase input is received. The user selects the price of the item corresponding to the input time point, subtracts it from the game money held by the user, and transmits the purchase information to the item database 30 to register the item in the database of the item held by the user.

At this time, the item purchase control unit 15 determines whether the user has valid purchase authority information. If the user has purchase authority information corresponding to the item and the validity period of the purchase authority information has not elapsed, the effective purchase is valid. It is determined that the authority information is held.

The item purchase control unit 15 loads the purchase authority information and the price change data from the server managing the price change data or the purchase option item management unit 12 to perform the above function.
