Next, as shown in FIG. 7, the service content delivery management module 250 supports registering service provider information stored in a database in the service registry SR using the service content delivery management menu 250A. And, it supports to transmit the service content stored in the database to the service provider (SP).

That is, the present invention can generate the service content by using a service content support tool (COST) designed for the creation and management of service content without providing a unique service content for each service provider and provide it to the service provider (SP). .

8 is a diagram illustrating an example of providing service content using a service content support tool according to an embodiment of the present invention.

Referring to FIG. 8, the server of Jeju National University and the Halla University of Jeju correspond to service providers (SPs), the service search management center corresponds to service registries (SRs), and users to the Jeju University server and Jeju Halla University through the Internet. It corresponds to a service client (SC) that accesses a server and uses an actual service.

For convenience of description, the service content support tool (COST) is installed on the content server, and the service content support tool (COST) is created and managed by the content server according to the administrator's input. The service content support tool (COST) can also be installed on other devices capable of Internet communication.

First, in the content server, service provider information is generated using the service content support tool (COST) according to the administrator's input, and the service provider information is generated and registered in the service registry SR.

In this case, the service provider information is generated through the service provider information management menu 240A of the service content support tool (COST), and the generated service provider information is registered in the service registry SR through the service content transmission management menu 250A. do.

Then, in accordance with the administrator's input on the content server, using the service content support tool (COST), as shown in ②, map information (original map, split map, mini map information, etc.) and node information (POI information, sensor / driving body) Service content including information).

At this time, the content server generates service content including map information and node information by using the map information management menu 220A and the node information management menu 230A of the service content support tool (COST). The explanation is as follows.

9 is a diagram illustrating a method of generating map information and node information in a service content support tool according to an embodiment of the present invention.

First, the original map image is divided into percentages (10% to 100%) to extract information of each segmented image, and then stored in a database along with metadata for retrieval.

Next, map the interest information, sensor information, and location information to the original map image, and then add the corresponding node and node-specific details to the database.

Referring back to FIG. 8, when the generation of the service content is completed, the content server generates the service content generated by using the service content delivery management menu 250A of the service content support tool (COST) as in step 3) according to an administrator's input. To the service provider SP.

Meanwhile, when a service is requested from the service client SC according to the user's request as in ④, the corresponding service provider SP provides the user with the service content transmitted from the content server as in ⑤.

10 and 11 illustrate the results of performance analysis of the service content support tool according to an embodiment of the present invention. The time for generating and transmitting service content in the service content support tool for performance analysis, and the service from the service client. Request time to receive the service content.

For reference, the generation of service contents was measured by loading, dividing and processing the same map image (1024 x 417 size map image in PNG format) in the service content support tool (COST) and recording it in a database. The transmission measured the time for transmitting the map information (1,884 KB) stored in the database to the service provider SP in the service content support tool (COST). In addition, the provision of the service content measured the time for requesting and receiving the content from the service client (SC) to the service provider (SP).

As shown in FIG. 10, the time taken to process and store a map image of 1024 x 417 size in the service content support tool (COST) is 32.512937 seconds on average, and the time taken to transmit service content of 1,884KB size is average. Was found to be 9.16380395 seconds.

As shown in FIG. 11, the time taken by the service client SC to receive the service contents from the service provider SP is 0.732292395 seconds on average.

That is, according to the present invention, a service content can be generated and provided using a service content support tool (COST) without building a unique service content for each service provider. This reduction can be devoted to the provision of service content can provide a more stable service to the service client (SC).

The preferred embodiments of the present invention have been described above. It is to be understood, however, that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and alternative arrangements included within the spirit and scope of the appended claims.
