Abstract

When a resource provision system linked to a cloud and a plurality of terminals receives a resource request signal transmitted from a terminal in order to relay and allocate resources to the terminal, which has requested resource allocation, the resource provision system checks whether user information containing a plurality of resource abandonment probabilities corresponding to the terminal, which has transmitted the resource request signal, is stored. If the user information is stored, resources to be allocated to the terminal are calculated by using a first resource abandonment probability of the terminal and a second resource abandonment probability of the terminal, which correspond to the plurality of resource abandonment probabilities, and then are allocated to the terminal.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

In the present specification, a terminal may be a communication terminal of various types such as a mobile terminal, a tablet terminal, a sensor terminal, a desktop computer, a notebook computer, and is referred to herein as an Internet of Things (IoT) terminal.

Hereinafter, a resource providing system and method according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings. In the embodiments of the present invention, for convenience of description, fog computing, a micro datacenter, or a smart gateway is referred to as a "resource providing system" in the sense of allocating resources and the concept of resource brokerage (broker). It is not necessarily limited to this.

1 is an exemplary diagram of an environment to which a resource providing system according to an exemplary embodiment of the present invention is applied.

As shown in FIG. 1, in the environment in which the resource providing system 100 according to an exemplary embodiment of the present invention is applied, a plurality of IoT terminals 200 are connected to a micro data center, that is, the resource providing system 100. The resource providing system 100 may be connected to the cloud 300 to connect the terminal 200 and the cloud 300. Here, the functions of the cloud 300 and the terminal 200 are already known, and detailed descriptions thereof will be omitted in the embodiments of the present invention.

Due to performance limitations of the terminal in a general IoT environment, the resource providing system 100 located in close proximity to the terminal may process the data in the cloud instead of performing the data processing, and if necessary, the cloud 300 having a larger resource It can also be done in. The structure of the resource providing system 100 that performs a function of a resource broker that allocates resources and sets a service price in consideration of data usage as well as resource usage of the terminal 200 in such an environment will be described with reference to FIG. 2. .

2 is a structural diagram of a resource providing system according to an embodiment of the present invention.

As shown in FIG. 2, the resource providing system 100 includes a resource request receiving unit 110, a user information storing unit 120, a resource allocating unit 130, and a cost processing unit 140.

The resource request receiving unit 110 receives a resource allocation request signal from the terminal 200. The resource allocation request signal includes service identification information requested by the user, identification information of the terminal 200, and classification information indicating a type (eg, PC, laptop, smartphone, tablet, etc.) of the terminal 200. . In the embodiment of the present invention, it is assumed that the basic resource usage for each service is set in advance, and the basic usage fee corresponding to the basic resource usage is set. In this specification, the fee for use (price) is assumed to be proportional to the amount of resources, and in some cases may be used in the same sense.

The user information storage unit 120 stores and manages user information for each terminal 200. Here, the user information includes identification information of the terminal 200, a first resource abandonment probability (AOP) of abandoning use of the total amount of resources requested by the terminal 200 regardless of the service, and the corresponding terminal 200. Each of these resources includes a second Service Oriented Probability (SOP) indicating how much of each of the resources for which the resource has been used and then abandoned has been given up for each service. If the terminal 200 requesting the resource requests the first resource, only the identification information of the terminal is newly generated and stored in the user information storage unit 120.

The resource allocator 130 may include a plurality of user information previously stored in the user information storage unit 120 based on identification information of the terminal 200 included in the resource allocation request signal received by the resource request receiver 110. The terminal checks whether user information corresponding to the terminal 200 requesting resource allocation is stored. If the user information is stored, the resource usage fee corresponding to the allocated resource amount or the allocated resource amount to be allocated to the terminal 200 is calculated based on the stored user information.

That is, the resource allocating unit 130 may determine a basic fee corresponding to the basic resource usage of the service, a first resource abandonment probability for the terminal 200, a second resource abandonment probability, and classification information (terminal type) of the terminal 200. Based on the calculation, the amount of resources required for the service use of the terminal 200 is calculated. If the terminal 200 requests a resource for the first time, the first resource abandonment probability and the second resource abandonment probability are calculated by reflecting a preset value (for example, 0.3). A method of providing a resource and a method of calculating a resource usage fee by the resource allocator 130 will be described later.

The cost processing unit 140 is a case in which the first refund processing or resource is used for resource renunciation caused by the terminal not using all of the resources, but only when the terminal pays the resource usage fee, but the cost must be refunded due to the deterioration of service quality. In accordance with the second refund processing, the refund cost is calculated to process the cost. The refund processing method of the cost processing unit 140 will be described later.

A method of providing resources using the resource abandonment probability of the terminal 200 by the resource providing system 100 described above will be described with reference to FIG. 3.

3 is a flowchart illustrating a resource providing method according to an embodiment of the present invention.

As shown in FIG. 3, the resource providing system 100 receives a resource request signal including service identification information, identification information, and identification information of a terminal to which resources are to be allocated from the terminal 200 (S100). The resource allocator 130 checks whether the user information is stored in the user information storage unit 120 based on the identification information of the terminal included in the resource request signal received in step S100 (S110).

If the terminal 200 has previously requested a resource allocation, the user information storage unit 120 has the identification information of the terminal 200 and the total resource allocation request amount so far requested by the terminal 200 regardless of the service. A first resource abandonment probability indicating a value for giving up use, and a second resource abandonment probability indicating how many resources abandoned use for each service among resources for which the terminal 200 requests resource allocation and then gives up use. have. However, if the terminal 200 has not previously requested resource allocation, only the identification information of the terminal is newly generated and stored in the user information storage unit 120.

According to the result confirmed in step S110, the resource allocation unit 130 calculates the resource to be allocated to the terminal 200 (S120, S130). Step S120 is a step of calculating the amount of resources to be allocated to the terminal 200 that has previously requested resource allocation, and step S130 is a step of calculating the amount of resource to be allocated to the terminal 200 that has never previously requested resource allocation. . In the process of calculating a resource, the resource allocator 130 calculates a resource amount for a terminal using Equation 1 below, and calculates a service price based on the resource amount.

Equation 1

는 제2 자원 포기 확률, σ²는 서비스 자원 포기 확률 변화량, Φ는 단말 구분 정보에 따른 값을 의미한다.Where R is the user fee to be paid by the user of the terminal 200 for the resources allocated to the terminal 200 for the service, U _i is the basic fee for the service i, Ω is the probability of giving up the first resource,

Is a second resource abandonment probability, σ ² is a change in service resource abandonment probability, and Φ is a value according to terminal identification information.

In this case, when using a service using a mobile terminal such as a mobile phone or a tablet among the user using the service, the resource usage information to be used may be changed a lot. Accordingly, since the exact service resource allocation is not easy due to the change of the resource use information being used, the change amount of the service resource abandonment probability is set. In the embodiment of the present invention, the change amount of the service resource abandonment probability is not limited to any one value, and the setting method is not limited to one method because the setting method may be performed through various methods.

의 값을 결정한다. 여기서

값은 자원 포기 확률이 높은 경우(H)와 낮은 경우(L)로 나누어 값을 결정할 수 있으며, 예를 들어 자원 포기 확률이 높은 경우에는

값을 0.5∼1의 값 중 어느 하나의 값을 갖도록 결정하고, 자원 포기 확률이 낮은 경우에는

값을 0.1∼0.5 중 어느 하나의 값을 갖도록 결정한다. In addition, the first resource abandonment probability (Ω) is a decision variable value assigned by the resource providing system 100 to each terminal 200.

Determine the value of. here

The value can be determined by dividing the probability of high resource abandonment (H) and the low case (L).

If the value is determined to have any value between 0.5 and 1, and the probability of abandonment of resources is low,

The value is determined to have any one of 0.1 to 0.5.

값을 0.3으로 결정한다. 이때, 자원 포기 확률의 높고 낮음을 결정하는 기준 역시 어느 하나의 기준 값으로 한정하지 않으며, 자원 포기 확률에 따라 또는 자원 할당을 요청한 적이 없는 경우에 결정되는

의 값을 반드시 이와 같이 한정하지는 않는다.In addition, if the terminal 200 has never requested resource allocation before,

Set the value to 0.3. In this case, the criterion for determining the high and low resource abandonment probability is not limited to any one reference value, which is determined according to the resource abandonment probability or when no resource allocation is requested.

The value of is not necessarily limited in this manner.

Φ, which is a value according to terminal identification information, indicates a type of a terminal using a resource for service use. In the embodiment of the present invention, only the type of the terminal is set to set the value of Φ, and detailed performance such as CPU or memory is not considered. For example, do not. For example, in order to provide a multimedia service to a user, the size of a display such as a monitor is important, and in an environment in which a resource providing system is applied, resources must be allocated according to the size and required quality of the display.

)이고, 두 번째 장치는 모바일 중에서 크기가 큰 제2 단말 그룹(

)이며, 마지막으로는 모바일 중에서 크기가 작은 제3 단말 그룹(

)이다. Therefore, embodiments of the present invention will be described using three types of service access devices as an example. The first device is a large first group of terminals (including desktop computers and laptops)

) And the second device is the second terminal group (

), And finally, the third terminal group (

)to be.

If it is assumed based on the value assigned to the first terminal group having a large size, the appropriate necessary resources to be allocated to the second terminal group and the third terminal group are respectively calculated by multiplying the weight values. In this case, it is assumed that the weight value of the resource requested by the second terminal group is larger than that of the third terminal group, and Φ, which is a value according to the terminal classification information, is calculated as in Equation 2 below.

Equation 2

After calculating the resources to be allocated to the terminal through the above step S120 and S130, the resource allocation unit 130 provides the resources to the terminal 200 requested in step S100 (S140). When the resource is provided through the step S140, the user of the terminal 200 pays for the corresponding resource.

When the resource usage fee is paid as much as the resource provided in step S140, the service is interrupted according to the situation of the service user, or when the resource abandonment occurs due to not using all the resources provided in step S140, the cost processing unit 140 Check whether the refund processing is necessary (S150). If it is confirmed that the refund process is not necessary, proceed to step S100. However, the refund amount calculation method when it is confirmed that the refund processing is required will be described with reference to FIG.

4 is a flowchart illustrating a cost refund method according to an embodiment of the present invention.

As shown in FIG. 4, in the embodiment of the present invention, when considering a refund policy, it is determined whether a refund is caused by resource renunciation or a refund due to a deterioration of service quality (S200). If the refund is for abandonment of resources, the cost processing unit 140 calculates the first refund amount ∂ _un (S210), and in the case of a refund due to deterioration in service quality, calculates the second refund amount ∂ _deg . (S220).

First, a method of calculating the first refund amount ∂ _un according to step S210 will be described. If the cost processing unit 140 uses more than 60% of the resources allocated to the terminal 200, and if not, The first refunded amount ∂ _un is calculated by dividing, and the following Equation 3 is used. At this time, the degree of resource use that is used as a reference for calculating the first refund amount ∂ _un is not necessarily limited to 60%.

Equation 3

을 다음 수학식 4와 같이 계산한다.In Equation 3, α means resource usage (%), and the unused resources abandoned by using the same

Is calculated as in Equation 4 below.

Equation 4

When more than 60% of the resources used, the cost processing unit 140 calculates the refund amount as shown in Equation 5 below.

Equation 5

Here, f / a means a service rate of the resource providing system to the resource usage, f is a service rate provided through the resource providing system 100, that is, fog. ω is a value rising variable and is calculated as shown in Equation 6.

Equation 6

If 60% or less of the resource is used, the cost processing unit 140 calculates the refund amount as shown in Equation 7 below.

Equation 7

Ε is a value drop variable, which is calculated as shown in Equation 8.

Equation 8

In order to calculate the amount of refund for resource abandonment, a value rising variable or a value falling variable is used depending on resource usage. This is because a service provider may sell idle resources to other users, so if a user uses less than 60% of the resource, a lower amount of refund is given, and if the user uses more than 60% of the resource, An example is described as taking a higher price, but is not necessarily limited to this.

On the other hand, when the method for calculating the second refund amount (∂ _deg ) according to step S220 will be described, the cost processing unit 140 calculates the second refund amount (∂ _deg ) through the following equation (9).

Equation 9

Here, Q _SLA refers to the quality of service provided on a service level agreement (SLA), which is an agreement between a service provider and a user, and Q _a refers to the quality of service actually provided through _a service. In this way, the amount of the refund is determined through the value of the actually provided service quality to the contracted quality.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
