IoT Resource Discovery Method and Server}

The present invention relates to an IoT service, and more particularly, to an IoT resource search method and server.

IoT (Internet of Things: Internet of Things) is a new information and communication foundation that connects all things that exist in the world through the Internet so that people and things, and things and things can communicate with each other anytime, anywhere.

IoT services will provide us with a more diverse, convenient and safer life. The premise for such various IoT services is to enable users to accurately search for a desired resource among a variety of resources that are widespread in the world.

However, the current IoT resource search method is not well-organized, so it is not possible to provide faithful search results that meet the user's intention. In addition, there is no countermeasure for side effects such as disclosure of information on resources requiring security.

The present invention has been conceived to solve the above problems, and an object of the present invention is to provide a resource search method and server that provide a faithful search result that meets the user's intention.

According to an embodiment of the present invention for achieving the above object, a resource search method includes: receiving a resource search request; Searching for a resource by filtering the resource range included in the search request according to a limited filter criterion; And providing a search result.

In addition, the search step may be performed when the format of the filter criterion is valid.

In addition, the resource may include at least one of a device, a set of devices, an application, a content, a context, and a service.

In addition, the filter may include a filter for at least one of a keyword, ID, location, and semantic information for the resource.

In addition, in the search step, only resources that are allowed to be disclosed among the resources filtered by the filter may be included in the search result.

In the search step, only resources that the user device can access among the resources filtered by the filter may be included in the search result.

In addition, the search step may limit the number of searched resources.

In the search step, a search result may be created by listing at least one of ID, name, location, and icon of the searched resource.

Meanwhile, according to another embodiment of the present invention, a resource search server includes: a communication unit for communicating with a user device; And a search unit that, upon receiving a resource search request from the user device, searches for a resource by filtering a resource range included in the search request according to a limited filter criterion, and provides a search result to the user device.

As described above, according to embodiments of the present invention, it is possible to provide a faithful search result that meets the user's intention. In addition, information can be protected for resources requiring security.

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

1 is a flow chart provided to explain an IoT resource search method according to an embodiment of the present invention.

IoT resources are physical or virtual components that provide useful information to users. The IoT resource includes a device, a set of devices (eg, a thermometer and an air conditioner), and an application. In addition, content, context, and service may be further included.

In FIG. 1, the user device 100 is a device carried by a user who wants to search for a resource, and the IoT server 200 is a server that provides resource information to the user device 100 because it holds information on a resource. .

As shown in FIG. 1, the user device 100 requests the IoT server 200 to search for a resource (S310). The resource search message transmitted from the user device 100 to the IoT server 200 in step S310 includes a filter criterion, a search option, and an output option.

Filter criteria are parameters that limit the range of a resource that the user wants to search for, and include a keyword, ID, location, and semantic information.

Search options include'Accessible' option and'Limit number' option. The'accessible' option is an option for searching only resources accessible to the user device 100 by the user. In addition, the'number limit' option is an option for limiting the number of resources to be provided to the user device 100 as a search result.

The output options are resource information to be listed in the search list. In the search list, resource IDs, names, icons, locations, etc. are listed according to output options.

In response to a resource search request from the user device 100 in step S310, the IoT server 200 performs a resource search using a search filter (S330). The resource search in step S330 is a process of filtering resources with a search filter according to filter criteria included in the resource search request message.

Meanwhile, performing a resource search in step S330 assumes that the received resource search request message is valid. For example, if the format of the filter criteria included in the resource search request message is not valid, the received resource search request message is discarded, and the resource search is not performed.

The resource search process performed in step S330 will be described in detail with reference to FIGS. 2 and 3.

Thereafter, the IoT server 200 transmits the resource search result in step S330 to the user device 100 (S350). Step S350 corresponds to a response to the resource search request in step S310.

Meanwhile, when there is no resource search result in step S330, the IoT server 200 may request a resource search from another configuration/server/system. Nevertheless, if there is no search result, a message for guiding that there is no resource searched in step S350 is transmitted to the user device 100.

The resource search process performed in step S330 will be described in detail below with reference to FIGS. 2 and 3.

2 is a flow chart provided to explain an IoT resource search method. As shown in FIG. 2, first, the IoT server 200 sets a search filter according to the filter criteria included in the resource search request received in step S310 (S331).

With respect to the filtered resource (ie, a resource that meets the filter condition) (S332-Y), the IoT server 200 determines whether to allow disclosure (S333). A resource allowed to be disclosed is provided to the user as a search result, but a resource that is not allowed to be disclosed is not provided to the user as a search result.

In the case of a resource allowed to be disclosed (S333-Y), the IoT server 200 determines whether the'accessible' option is selected as a search option by the user (S334). If it is found that the corresponding option is not selected (S334-N), the IoT server 200 adds this resource to the search result (S336).

On the other hand, if it is determined that the corresponding option is selected (S334-Y), the IoT server 200 determines whether the user device 100 can access the filtered resource (S335). Step S335 is performed by a procedure for checking whether the user device 100 has access rights to the filtered resource.

If it is found to be an accessible resource (S335-Y), the IoT server 200 adds this resource to the search result (S336). On the other hand, if it is found to be an inaccessible resource (S335-N), the IoT server 200 does not add this resource to the search result.

Steps S331 to S336 continue until all resources registered in the IoT server 200 are completed (S337).

When filtering/checking for all registered resources is completed (S337-Y), a process of creating a search result to be provided to the user device 100 is performed. This process will be described in detail with reference to FIG. 3.

As shown in FIG. 3, when filtering is completed for all registered resources (S337-Y), it is checked whether "limit=N" is set as a search option by the user (S338). "limit=N" is a search option for limiting the number of resources to be included in the search result to within N.

When "limit=N" is set (S338-Y), the IoT server 200 determines whether the number of filtered resources exceeds N (S339). If it is found that the number of filtered resources exceeds N in step S339 (S339-Y), the IoT server 200 selects N of the filtered resources (S340).

N number of resources can be selected based on ID matching, keyword matching, and location proximity, and detailed settings can be made by setting the priority for ID matching with the highest and lowest location proximity. Do.

Meanwhile, when "name & icon" is set as an output option by the user (S341-Y), the IoT server 200 generates a search result by listing IDs, names, and icons of resources (S342).

On the other hand, when "location" is set as an output option by the user (S343-Y), the IoT server 200 generates a search result by listing IDs and locations of resources (S344).

4 is a detailed block diagram of the IoT server 200 shown in FIG. 1. As shown in FIG. 4, the IoT server 200 includes a communication unit 210, a registration unit 220, a search unit 230, a management unit 240, and a DB 250.

The communication unit 210 is a means for communication connection with the user device 100. The registration unit 220 registers resource information in the DB 250. The management unit 240 manages updating of resource information registered in the DB 250.

The search unit 230 performs a resource search according to the procedures shown in FIGS. 2 and 3 and returns the search result to the user device 100 through the communication unit 210.

In addition, although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. In addition, various modifications are possible by those of ordinary skill in the art, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
