The present invention relates to a method for providing the advertisement by correcting the guarantee of the advertisement sold in the form of Cost Per Mill (CPM) every unit time, and a system for performing the method, and more particularly, a predetermined unit time. The method of performing and transmitting the ad guarantees of the next unit time to a plurality of ad transmission servers in each ad execution control server and controlling the amount of transmission of the advertisements using the ad guarantees in the ad transmission server. It is about a system.

The banner advertisement refers to a form of advertisement in which a content to be promoted on a portion of a web page is attached in the form of a graphic image. It looks like a banner and is called a banner. It is a form of paying a predetermined advertising fee by using a video file or the like to pay a predetermined advertisement. The banner advertisement may inform the advertiser by counting the number of times the banner advertisement is shown to users or the number of times the graphic of the banner advertisement is downloaded in a certain period to analyze the advertising effect.

Initially, it started out as a simple form that informed the domain and business contents in a square shape, but nowadays it is diversified to be fixedly placed on the screen when a video or a homepage is opened.

Such banner ads are generally sold in the form of Cost Per Mill (CPM). CPM refers to the advertising fee paid for 1,000 ad impressions, which means flat ad. If the CPM is 100 won, it means that the advertising cost for exposing an ad 1,000 times is 100 won, which is usually based on the advertisement cost of the banner at the top or bottom of the first page of the web page. Mill represents 1,000 in Roman numerals.

In the system providing advertisements, the daily and hourly exposure rate of advertisements sold by these CPMs should be kept constant for the duration of the contract.

1 is a view showing an overview of a system for providing an advertisement in the prior art.

The plurality of advertisement transmission servers 101 share the guarantees of the advertisements sold in the CPM at the same rate to expose the advertisements to the user terminal 103 to provide the advertisements to the user terminal 103 via the network 102. . However, in a multi-server environment for processing one billion requests per day, the advertisement delivery server 101 sharing the guarantee of advertisements at the same rate has difficulty in guaranteeing the promised guarantee when a temporary failure occurs in a specific advertisement delivery server 101. You owe it.

In addition, when the PV (Page View) of the service surface is suddenly increased or decreased by the user terminal 103 due to an unexpected factor, the imp (impression: exposure of the banner advertisement once opened on a specific web page is exposed). In this case, an increase or decrease in a single exposure, called one impression, should be compensated for the remaining time.

As described above, the system for providing an advertisement in the related art determines the amount of advertisement delivery the next day based on the amount of advertisements aggregated on a daily basis through log processing, and rolls the advertisements at a rate of daily guarantee. Therefore, when the error due to the change in the daily traffic trend is severe, there is a problem of achieving the target transmission much earlier than the end date of the advertisement. On the contrary, since all advertisements are executed at a ratio, the achievement of exceeding a certain amount of advertisements causes a problem that some advertisements are not achieved.

The present invention to solve the problems of the prior art, a method for providing the advertisement by correcting the guarantee of the advertisement sold in the form of Cost Per Mill (CPM) every unit time and a system for performing the method Suggest a technique.

The present invention calculates the amount of unit time transmission for the advertisement to be transmitted at the next unit time during the predetermined unit time in the advertisement execution control server for controlling the advertisement transmission server, and transmits to the plurality of advertisement transmission servers. It aims to control and provide the amount of advertisement transmission.

Another object of the present invention is to stabilize the advertisement by processing the transmission amount of the advertisement that was not achieved in the previous unit time due to the decrease of the PV (Page View) or the exposure of the advertisement in a specific advertisement transmission server through the correction of the transmission amount per unit time To maintain the transmission rate.

In order to achieve the above object and to solve the above-described problems of the prior art, a method for providing an advertisement sold in the form of Cost Per Mill (CPM) according to an embodiment of the present invention, pre-determined in the advertisement execution control server (predetermined) processing the advertisement information received through the advertisement transmission server every unit time, calculating a unit time transmission amount for exposing the advertisement for the next unit time based on the advertisement information; and at the advertisement transmission server And transmitting the advertisement to the user terminal based on the unit time transmission amount.

According to one aspect of the present invention, the advertisement information includes a transmission amount of the exposure of the advertisement during the unit time, the step of processing the advertisement information received through the advertisement transmission server at a predetermined unit time in the advertisement execution control server The method may include continuously storing the advertisement information received from the advertisement transmission server, calculating a daily execution amount by adding up the advertisement information in units of days, and using a difference between the daily execution amount and a daily guarantee of the same date. The method may include calculating an amount that is insufficient of the advertisement.

According to another aspect of the invention, the step of calculating a unit time transmission amount for exposing the advertisement for the next unit time based on the advertisement information, the average inventory guarantee based on the day guarantee, the day execution amount and the day surplus time Calculating an average unfulfilled amount based on the undeliverable amount until the last day and the end surplus time until the end time of the advertisement; and transmitting a transmission amount per second by giving a current time weight to the sum of the average stock guarantee and the average unfulfilled amount. And calculating the unit time transmission amount through the transmission amount per second during the unit time.

According to another aspect of the present invention, the step of calculating the average stock guarantee based on the day guarantee, the day execution amount and the day surplus time, the step of calculating the amount of the day unsatisfactory that is the difference between the day guarantee and the day execution amount And calculating the average inventory guarantee by calculating the amount of unachieved amount per day surplus time.

According to another embodiment of the present invention, a system for providing an advertisement sold in the form of a CPM includes: an advertisement execution control server and the unit time calculating a unit time transmission amount for exposing the advertisement for the next unit time every predetermined unit time; And an advertisement transmission server for transmitting the advertisement to the user terminal based on the amount of transmission.

Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

2 is a view showing an overview of a system for providing an advertisement according to an embodiment of the present invention. As shown in FIG. 2, the advertisement providing system provides advertisements sold in a CPM form from the plurality of advertisement transmission servers 201 to the user terminal 203 via the network 202, and centrally transmits the advertisements. Ad execution control server 204 that can be controlled in real time.

The use of the advertisement execution control server 204 is a problem when the advertisement is not exposed due to a temporary failure or the like in a specific advertisement transmission server 201 or a sudden increase or decrease of a request for the advertisement from the user terminal 203 occurs. It is possible to maintain a stable transmission rate by resolving and processing the guarantee of the advertisement that has not been achieved in the previous cycle.

In this case, in order to solve the problem and maintain a stable transmission rate, the advertisement execution control server 204 receives the transmission amount of the advertisement exposed during the current unit time from the advertisement transmission server and exposes it for the next unit time using the transmission amount. After calculating the unit time transmission amount of the advertisement for the transmission to the advertisement transmission server 201.

At this time, the advertisement transmission server 201 provides the advertisement to the user terminal for the next unit time based on the unit time transmission amount, thereby controlling the transmission amount of the advertisement in the advertisement execution control server 204 to maintain the stable transmission rate. It becomes possible.

A method of providing such an advertisement will be described in more detail with reference to FIGS. 3 to 5.

3 is a flowchart illustrating a method for providing an advertisement sold in Cost Per Mill (CPM) form according to an embodiment of the present invention.

In operation S310, the advertisement execution control server for controlling the transmission amount of the advertisement sold in the form of CPM processes the advertisement information received through the advertisement transmission server every predetermined unit time from the advertisement execution control server. In this case, the advertisement information may include a transmission amount of the advertisement for the unit time. Such a step S310 may include steps S311 to S313 as shown in FIG. 3.

In step S311, the advertisement execution control server continuously stores the advertisement information received from the advertisement transmission server. In this case, the advertisement execution control server may classify and store the amount of transmission of the advertisement included in the advertisement information by date.

In step S312, the advertisement execution control server calculates the daily execution amount by summing the advertisement information on a daily basis. In this case, the daily execution amount means that the amount of the advertisement actually exposed the advertisement for one day is counted.

In step S313, the advertisement execution control server calculates an insufficient amount of the advertisement through the difference between the daily execution amount and the daily guarantee of the same date. That is, the shortage or excess amount of the transmission amount of the advertisement through the difference between the daily execution amount, which is the amount of actually executing the advertisement on the same day, and the daily guarantee amount of the advertisement determined during the exposure period of the advertisement. The amount that is not reached may be calculated and used to calculate the unit time transmission amount, which is the transmission amount of the advertisement during the next unit time.

In step S320, the advertisement execution control server calculates a unit time transmission amount for exposing the advertisement for the next unit time based on the advertisement information.

In the case of determining the guarantee of the advertisement on a daily basis, as described, the advertisement allocated to the advertisement transmission server may be reduced due to a sudden increase or decrease of PV (Page View) due to a temporary failure or an unexpected factor for a specific advertisement transmission server. You may not be able to fill all of your guarantees. Therefore, by collecting and collecting the amount of the advertisement transmitted from each advertisement transmission server for each unit time, calculates the unit time transmission amount which is the guarantee of the advertisement to be exposed for the next unit time, and transmits it to the advertisement transmission server, and the advertisement The transmission server can control the transmission amount of the advertisement by correcting the guarantee of the advertisement every unit time (for example, 5 minutes).

The method of calculating the unit time transmission amount will be described in more detail with reference to FIG. 5.

In step S330, the advertisement transmission server transmits the advertisement to the user terminal based on the unit time transmission amount. In this case, the advertisement transmission server exposes the advertisement to the user terminal during the unit time through the unit time transmission amount received through the advertisement execution control server.

Further, the advertisement transmission server generates the advertisement information based on the transmission amount of the advertisement and transmits the advertisement information to the advertisement execution control server so that the advertisement execution control server generates the unachievable amount based on the advertisement information and then the next unit. It can be used to calculate the unit time transmission amount of time.

In this way, the plurality of advertisement transmission servers transmits the amount of advertisements exposed during the unit time to the advertisement execution control server, and the advertisement execution control server collects and aggregates the amount of transmission to generate the unachieved amount, and then the next unit time. By calculating the unit time transmission amount, which is the guarantee of the advertisement for exposing, to the advertisement transmission server, the advertisement transmission server can expose the advertisement at a stable transmission rate.

4 is an example for explaining a method for calculating an underachiever. In FIG. 4, a bar graph shows a daily guarantee (solid line) set for each day for any advertisement exposed for a week (month to day). In addition, the daily execution amount, which is the actual transmission amount of the day, is indicated by a dotted line.

In this case, as described with reference to FIG. 3, the amount of underachiance may be calculated through the difference between the daily guarantee and the daily execution amount set for each day during the period 401 until yesterday.

For example, the difference between the daily guarantee and the daily execution amount may be calculated as a non-achieving amount 402 having a positive number 10 and a non-achieving amount 403 having a negative number 20 on a Wednesday. Here, the positive underachiever 402 means that the daily guarantee set for exposing the advertisement for Monday has not been achieved by 10, and the negative underachiever 403 means that the daily underrun amount has been exceeded by 20. do.

The unachieved amount during the period 401 calculated on a daily basis may be used to calculate the unit time transmission amount for transmitting the advertisement during the next unit time of today 404, which will be described with reference to FIG.

5 is a flowchart illustrating a method of calculating a unit time transmission amount according to an embodiment of the present invention. As illustrated in FIG. 5, steps S510 to 550 may be included in step S320 described with reference to FIG. 3.

In step S510, the advertisement execution control server for controlling the plurality of advertisement transmission servers calculates an average inventory guarantee based on the guarantee of the day, the amount of execution of the day, and the surplus time of the day. In this case, the same day guarantee may mean the amount of advertisements to be exposed on the same day for any advertisement, and the same day execution amount may mean the amount of the advertisements exposed to the current time of the guarantee on the same day.

In addition, the step (S510) is the step of calculating the day unachieved amount that is the difference between the day guarantee and the day execution amount (S511) and the step of calculating the average inventory guarantee by calculating the day underage amount per surplus time of the day ( S512) may be included. In this case, the average stock guarantee may be calculated through a division operation of the amount of unachieved day and the surplus time of the day.

In step S520, the advertisement execution control server calculates an average underachiever based on an underachiever until the last day and an end surplus time until the advertisement end time. In this case, step S520 may include calculating an unachieved sum based on the sum of the unfulfilled amounts (S521) and calculating the average unachieved amount through the sum of the unaccepted amounts per the end surplus time (S522). Can be.

In step S530, the advertisement execution control server calculates a transmission amount per second by assigning a current time weight to the sum of the average inventory guarantee and the average underachiever. In this case, step S530 may be a step of calculating the unit time transmission amount through a multiplication operation of the transmission amount per second and the unit time.

In step S540, the advertisement execution control server calculates the unit time transmission amount through the transmission amount per second during the unit time. In this case, the unit time transmission amount may be calculated through a multiplication operation of the transmission amount per second and the unit time.

That is, the unit time transmission amount may be expressed by Equation 1 through steps S510 through S540.

In step S550, the advertisement execution control server transmits guarantee information including the unit time transmission amount to the advertisement transmission server. At this time, the advertisement transmission server exposes the advertisement for the next unit time based on the unit time transmission amount as described in FIG.
