Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In the embodiment of the invention, the uniform-speed delivery control is carried out by taking the media data promotion plan as a basic unit, and the media data promotion plan comprises a plurality of media data with the same promotion theme. In order to meet the uniform-speed delivery requirement of media data in a media data promotion plan, the related consumption conditions of the media data promotion plan in the first t time units in a preset time period are counted, the delivery probability of the media data in the t +1 th time unit is determined according to the counting result, and delivery control is performed on the media data in the media data promotion plan according to the delivery probability of the media data. The media data here may be advertisements.
Referring to fig. 1, fig. 1 is a schematic diagram of a media data constant-speed delivery control system according to an embodiment of the present invention, which includes a media data subsystem and a device/apparatus for controlling media data constant-speed delivery, wherein,
the media data subsystem is composed of one or more service devices. The media data subsystem is mainly responsible for executing operations related to a media data promotion plan, for example, a media data request of a media data display platform is received (for example, when a certain webpage of a website is opened, the media data request is triggered, the media data request is sent to the media data subsystem of a background), the media data is sent to the media data display platform according to the current media data release probability of the media data promotion plan, and the media data display platform displays the media data sent by the media data subsystem to a client (for example, a user browsing the webpage), so that media data release is realized. The media data subsystem further needs to perform operations such as exposure and click condition statistics and fee deduction of media data of the media data promotion plan, and accordingly notifies the related consumption information of the media data promotion plan to a device for controlling media data to be released at a constant speed, wherein the related consumption information of the media data promotion plan includes: the media data promoter corresponds to the consumption limit of the media data promotion plan, the consumption limit of the media data promotion plan in the preset time period, the consumption amount of the media data promotion plan in each time unit and the like in the preset time period.
The device for controlling the media data to be launched at a constant speed is responsible for calculating the launching probability of the media data promotion plan in the later time unit when the previous time unit is finished or the later time unit is started, so that the media data subsystem pushes the media data of the media data promotion plan to the media data display platform according to the launching probability of the media data. In the concrete implementation, the device for controlling the uniform-speed delivery of the media data can acquire the related consumption information of the media data promotion plan from the media data subsystem in real time, and the related consumption information of the media data promotion plan is counted to obtain the statistical results (specifically, explained in the following embodiments) of the account consumption amount of the media data promoter in the previous t time unit in each preset time period, the account balance of the media data promoter up to t time unit, and the total consumption amount of the media data promotion plan in the previous t time unit, further calculating the available balance of the media promotion plan until t time unit according to the statistical result, and calculating the media data putting probability of the media data promotion plan in the t +1 time unit based on the available balance, therefore, the media data subsystem can carry out delivery control on the media data in the media data promotion plan according to the media data delivery probability.
Referring to fig. 2, fig. 2 is a flowchart of a method for controlling media data to be delivered at a constant speed according to an embodiment of the present invention, where the method mainly includes the following steps:
step 201, acquiring a consumption limit of a media data promoter corresponding to a media data promotion plan in a preset time period and a consumption limit of the media data promotion plan in the preset time period.
Media data delivery belongs to paid services, usually a consumption limit needs to be set, and media data delivery is stopped when consumption exceeds the limit. When the media data is an advertisement, correspondingly, the media data promoter is an advertiser, and the advertisements in the media data promotion plan belong to the same advertiser.
In practice, a media data promoter may participate in multiple media data promotion programs and have a consumption account in which prepaid charges that the media data promoter has deposited for participating multiple media data promotion programs are stored.
In general, a media data promoter will specify the consumption limit of each participating media data promotion plan, and after the consumption limit is evenly distributed to the duration of the media data promotion plan, the consumption limit corresponding to the media data promotion plan by the media data promoter in a preset time period can be obtained.
In addition, the media data promotion plan also has a definite consumption quota, and the consumption quota of the media data promotion plan in a preset time period (for example, 1 day) can be obtained after the duration of the media data promotion plan is shared.
In the embodiment of the invention, the consumption limit of the media data promoter corresponding to the media data promotion plan in the preset time period and the consumption limit of the media data promotion plan in the preset time period need to be obtained from the media data subsystem in advance for subsequent media data delivery probability calculation.
Step 202, in each preset time period, counting the account consumption amount of the media data promoter in the previous t time unit, the account balance of the media data promoter up to the t time unit, and the total consumption amount of the media data promotion plan in the previous t time unit, and calculating the available balance of the media promotion plan up to the t time unit according to the counting result.
Each preset time period should include a duration of at least one time unit.
In practical applications, each exposure and each click of the media data has a corresponding amount of consumption according to specific situations. The media data promotion system can accumulate the consumption amount of each media data promoter according to the specific exposure and click condition of the media data in the operation process to obtain the account consumption amount of the media data promoter within a preset time period and the account balance of the media data promoter within a preset time unit up to t time unit (t is a natural number greater than 0, and the time unit can be wonderful, minute, hour and the like); meanwhile, the total consumption amount of the media promotion plan which is up to t time units in the preset time period can be accumulated according to the specific exposure and click conditions of the media data.
After the account consumption amount of the media data promoter in the previous t time unit, the account balance of the media data promoter up to the t time unit and the total consumption amount of the media data promotion plan in the previous t time unit are obtained through statistics, the available balance of the media data promotion plan in the preset time period can be determined according to the statistical result, and the specific method comprises the following steps: and comparing the account balance of the media data promoter up to t time unit, the difference value between the consumption limit of the media data promoter in the preset time period and the account consumption amount in the previous t time unit, and the difference value between the consumption limit of the media data promotion plan in the preset time period and the total consumption amount in the t time unit, and determining the minimum value as the available balance of the media promotion plan.
Step 203, calculating the media data delivery probability of the media data promotion plan in the t +1 time unit based on the available balance, and delivering the media data in the media data promotion plan according to the calculated media data delivery probability.
