Description

Method for selling and purchasing M2M dataset with M2M data marketplace

The present invention relates to a machine to machine (M2M) related technology, and more particularly, to a data transaction method for selling and purchasing data stored as a resource in an M2M platform.

From a platform point of view, data purchase corresponds to acquiring data access rights, so it is possible to provide services by developing a function such as an ACP (Access Control Policy) manager. However, there is a problem in that it is not easy to set the authority between the seller and the buyer in data transaction linked to the ACP.

Furthermore, since various types of data are stored in resource units in the M2M platform, it is necessary to combine them in various ways so that they can be sold/purchased.

Accordingly, there is a need for a method to make it possible to easily set the authority of sellers and buyers and to sell/purchase multiple resources while conforming to the current oneM2M standard.

The present invention has been devised to solve the above problems, and an object of the present invention is to facilitate the establishment of rights in the sale and purchase of resources stored in the M2M platform, and to integrate multiple resources to sell and To provide a way to purchase.

According to an embodiment of the present invention for achieving the above object, a method for selling a dataset includes a first generating step of creating a dataset resource in which information for selling a dataset integrating multiple resources stored in an M2M platform is stored; a second generation step of creating a purchasing resource in which information for purchasing a dataset in which the dataset resource is created is stored; and providing resources constituting the dataset with reference to the dataset resource when the purchase resource is created.

The dataset resource may store an ID list of resources constituting the dataset or filter conditions of resources constituting the dataset.

The dataset resource may further store at least one of information of a seller who requested to sell the dataset, a sales policy set by the seller, and an attribute indicating whether to sell the dataset.

The second generation step may be to create a purchase resource under the dataset resource.

The providing step may include: creating subscription resources under the resources constituting the dataset; and storing the ID list of subscription resources in the purchase resource.

The first generating step further includes the step of creating a point resource below the dataset resource, and the providing step, when the point resource is inquired, collects resources linked to the dataset resource located above the point resource and returning it; may further include.

The return phase collects the <latest> resource of the <container> resource for the <container> resource, collects the <latest> resource of the <timeSeries> resource for the <timeSeries> resource, and collects the <flexContainer> resource for the <flexContainer> resource. It may be to collect the latest <flexContainerInstance> resource among sub <flexContainerInstance> resources created in > resource or <flexContainer> resource.

Meanwhile, according to another embodiment of the present invention, the M2M system includes a communication unit communicating with a data marketplace server; And when receiving a request to sell a dataset integrating multiple resources stored in the M2M platform from the data marketplace server through the communication unit, create a dataset resource in which sales information is stored, and purchase the dataset in which the dataset resource is created and a processor that generates a purchase resource in which purchase information is stored when a request is received from the data marketplace server through the communication unit, and provides resources constituting the dataset with reference to the dataset resource when the purchase resource is created.

As described above, according to embodiments of the present invention, by integrating multiple resources stored in the M2M platform, sales and purchases can be made in units of data sets, thereby increasing the convenience of both sellers and buyers.

In addition, according to embodiments of the present invention, a <dataset> resource for managing data set sales information and a <purchase> resource for managing data set purchase information are created/managed, so that the authority setting and sales policy of sellers and buyers are established. The purchase method can be applied in a simple way, improving the convenience of setting up and managing dataset transactions, ultimately enabling dataset transactions.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

In an embodiment of the present invention, a transaction method for selling and purchasing a dataset integrating multiple resources stored in the oneM2M platform is presented.

Here, the dataset is a set of multiple resources stored in the oneM2M platform owned by a specific owner.

1. Dataset sales/purchase system

1 is a diagram illustrating a data set sales/purchase system to which the present invention is applicable. The dataset sales/purchase system is configured to include a user 100 , an App 200 , a marketplace 300 , and a oneM2M platform 400 as shown.

The user 100 collectively refers to a terminal of a seller who registers to sell a dataset and a terminal of a buyer who requests to purchase the dataset. App 200 means a terminal in which an application for receiving the data set purchased by the purchaser 100 is installed.

The marketplace 300 is a portal server that enables a data transaction service by receiving a sale request and a purchase request from the user 100 and transmitting the received request to the oneM2M platform 400 . The HMI main screen provided by the marketplace 300 is illustrated in FIG. 2 .

The oneM2M platform 400 is a server system that processes a data set sale request and a data set purchase request transmitted through the marketplace 300 , and provides a data set to the App 200 according to the purchase request.

2. Dataset registration

When the seller 100 requests to sell the dataset through the marketplace 300 , the Common Service Entity (CSE) of the oneM2M platform 400 receives the request through the marketplace 300 and registers the dataset. .

The dataset is a set of shareable resources owned by the seller 100 (ie, stored by the seller 100) among the resources stored in the oneM2M platform 400 . In that the resources constituting the dataset correspond to DSR (Data Sharing Resource), the two may be used interchangeably below.

As shown in FIG. 3, a set of <container> resources may be a dataset, and as shown in FIG. 4, a set of <flexContainer> resources may be a dataset, as well as a set of <timeSeries> resources This dataset could be

Furthermore, it goes without saying that a set of different types of resources, such as a set of <container> resource and <flexContainer> resource, or a set of <flexContainer> resource and <timeSeries> resource, may also be a dataset.

5 shows a single resource, which is a concept distinct from a dataset. Unlike a dataset, which is a set of multiple resources, a single resource means only one resource.

For data set registration, the CSE of the oneM2M platform 400 configures a dataset by inquiring resources that the seller 100 wants to sell with the AE-ID of the seller 100, and <dataset in which information about the dataset is stored. > Create a resource.

6 illustrates an example of creating a <dataset1> resource for registering a dataset including a <flexCnt1> resource and a <flexCnt2> resource. As shown in FIG. 6 , the <dataset> resource contains metadata about the dataset, and the metadata includes the following data.

- resIDs(resourceIDs)

ID list of resources that make up the dataset

- resFilter(resourceFilter)

As a filter condition for configuring the dataset by selecting resources, the configuration of the dataset is flexible in that resources can be created/updated/deleted in the future.

- ownership

Owner information of the seller who requested to sell the dataset, which can be AE-ID or User-ID

- license : license

License policy information for the provided dataset set by the seller, which is the license information to be applied when the buyer acquires and uses the data

- salesPolicy

Selling policy set by the seller. Maximum traffic per day (maxDailyTrafficSize), maximum number of offers per day (maxDailyCallCount)

- active/inactive

Property indicating whether to sell. If the data set requested for sale is confirmed and available for purchase, e.g. through the datamarketplace portal administrator, it is set to active, otherwise it is set to inactive.

Above, setting resIDs and resFilter is optional. That is, the dataset can be determined by any one of resIDs and resFilter.

Meanwhile, the <dataset> resource has a <retreivalPoint> resource as a virtual child resource. As will be described later in detail, the <retreivalPoint> resource is a point for retrieving resources constituting the dataset.

3. Purchase a subscription-based dataset

When the purchaser 100 requests to purchase the dataset being sold through the marketplace 300, the CSE of the oneM2M platform 400 receives the request through the marketplace 300, Create a <purchase> resource in which purchase information is stored under the dataset> resource.

7 illustrates a result of creating a <purchase1> resource under the <dataset1> resource to purchase the sold dataset1.

You can retrieve, update, and delete the created <dataset>/<purchase> resource.

To provide a dataset on a subscription basis, CSE creates <subscription> resources under each of the resources constituting the dataset, and stores the ID list (eg subscriptionIDs) of <subscription> resources in the <purchase> resource. .

As shown in FIG. 7 , the following attributes are stored in the <purchase> resource in addition to subscriptionIDs.

- subscriptionEnabled

If subscriptionEnabled = TRUE, pointOfAccess of <AE> is set as notificationURI of <subscription> or AE-ID is set as notificationURI. Thereby, it is possible to notify the dataset to the App (200).

- notificationURI

If the data set buyer directly sets notificationURI to a specific URI, the URI is set as the notificationURI of the child <subscription> resource that is created in each resource constituting the dataset.

- notificationEventType

Set the event type to be notified according to the resource type constituting the dataset (e.g., a notification is performed when a sub-resource is created or a notification is performed when a resource is updated)

On the other hand, when resources constituting the dataset in the <dataset> resource are set to resFilter instead of resIDs, subscriptionUpdateInterval for setting the update cycle of <subscription> resources in the <purchase> resource may be further added.

- usageInfo

As information to store the usage status of the upper dataset resource being used by the buyer, it may include, for example, information such as currentCallCount and currentRetrievalDataSize. When the buyer uses the data, the CSE of the oneM2M platform 400 may update the corresponding attribute value.

4. Retrieve-based dataset purchase

If the buyer 100 purchases a dataset being sold through the marketplace 300 and the CSE of the oneM2M platform 400 creates a <purchase> resource for the dataset, retrieve the dataset It is also possible to obtain

Specifically, as shown in FIG. 8, when the App 200 inquires the <dataset>/<retreivalPoint> resource, the CSE configures the dataset linked to the <dataset> resource, which is a parent resource of the <retrievalPoint> resource. It collects and returns resources.

This corresponds to the case where the dataset is set as resIDs in the <dataset> resource. If the dataset is set as resFilter in the <dataset> resource, CSE filters and searches the resources according to resFilter, collects them, and then returns them.

The owner of the <purchase> resource, i.e. the purchaser, has access to the <dataset>/<retrievalPoint> resource. <retrievalPoint> resource is not allowed to create/update/delete by user.

When collecting the resources constituting the dataset, the <container> resource can be set to collect the <latest> resource of the <container> resource, that is, the latest <contentInstance> resource.

Also, for the <timeSeries> resource, it can be set to collect the <latest> resource of the <timeSeries> resource, that is, the latest <timeSeries> resource.

However, these are merely exemplary. It can be changed to collect the <oldest> resource of the <container> resource (the oldest <contentInstance> resource) or the <oldest> resource of the <timeSeries> resource (the oldest <timeSeries> resource) through designation using an indication. , for <flexContainer> resources, it can be set to collect the latest <flexContainerInstance> resource from among the <flexContainerInstance> resources created in the <flexContainer> resource or the <flexContainer> resource.

However, this, too, is merely exemplary. It can be changed to collect past <flexContainerInstance> resources through designation using indication.

5. oneM2M platform

9 is a detailed block diagram of the oneM2M platform 400 shown in FIG. 1 . As shown, the oneM2M platform 400 is configured to include a communication unit 410 , a processor 420 and a storage unit 430 .

The communication unit 410 is a communication interface means for communicating with an external device including the App 200 and the marketplace 300 and accessing an external network.

The processor 420 is configured to execute at least one Application Entity (AE) and a Common Service Entity (CSE), and performs procedures necessary for the data set sales and purchase service presented above.

The storage unit 430 provides a storage space necessary for the processor 420 to perform data set sales and purchase services.
