The automatic deletion time limit information 740 is an item that designates a time when the corresponding interest request information registered by the service provider is automatically deleted.

Next, the content service providing method of the present invention by the above-described configuration will be described sequentially.

The content service providing process using the service repeater according to the present invention may be classified into a content service request process, a content service relay process, and a content service providing process.

6 is a flowchart illustrating a content service request process according to an exemplary embodiment of the present invention.

Referring to FIG. 6, when a user requests to receive a specific content service, the user query input unit 110 of the service request device 100 creates a service search query to register a query of the service relay device 200. Transmit to unit 210. The service search query is written after obtaining a service classification category stored in the service storage device 400 through the service relay device 200 and providing the service classification category to the user. , The service category and the search keyword.

Accordingly, the registration query unit 210 of the service relay apparatus 200 that has received the service search query transmits service provision information that satisfies the received service search query (ie, service category and search keyword). Search for and transmit the result to the user query input unit 110 of the service request apparatus 100.

Therefore, the user query input unit 110 of the service request device 100 receives a service search result for a service search query requested from the registration query unit 210 of the service relay device 200 after a service search query request. It is determined whether there is satisfactory service provision information (S120, S130).

If the service provision information satisfies the above step S130, the user query input unit 110 of the service request device 100 obtains the service proxy information from the registration query unit 210 of the service relay device 200 (S170). . At this time, the user query input unit 110 of the service request apparatus 100 provides the obtained service proxy information to the service call unit 120, and the service call unit 120 based on the obtained service proxy information. Obtain service proxy object information stored in the service proxy container 220 of the service relay device 200.

Then, the service caller 120 calls the corresponding content service from the service providing apparatus 300 using the obtained service proxy object information (S180). In response to the content service being provided from the service providing apparatus 300, the user interface 130 executes an application program to provide the provided content service to the user.

On the other hand, if there is no service providing information satisfied in step S130, the user query input unit 110 determines whether there is a service registration request of the content from the user (S140). If it is determined that there is no service registration request from the user, the user query input unit 110 terminates the content service request process.

On the contrary, if there is a request for registering a service request from the user in step S140, the user query input unit 110 receives the attribute value defined in the content service request information table 600 of the service storage device 400 from the user. The received information is provided to the registration query unit 210 and registered in the service request information table 600 of the service storage device 400 (S150).

Thereafter, the user query input unit 110 waits for service proxy information indicating the occurrence of service provision for the registration service request from the registration query unit 210 in the background (S160).

After the service proxy information is input, the user query input unit 110 of the service request device 100 obtains the service proxy information provided from the registration query unit 210 of the service relay device 200 and performs step S170 accordingly. . That is, when the service caller 120 calls the request for the corresponding content service included in the service proxy object information obtained to the service providing apparatus 300, and correspondingly, the content service is provided from the service providing apparatus 300. The application 130 is executed through the interface 130 to provide the provided content service to the user (S180).

According to the service request process, the user can search for and call a desired content service. In addition, if a desired content service does not exist, the user can register a service request for it, and when the corresponding content service is provided, related service provision information will be provided. You may be informed.

Next, Figure 7 is a flow diagram illustrating a content service relay process according to a preferred embodiment of the present invention. The service relaying process refers to a process in which the service relaying device 200 relays a service between the service requesting device 100 and the service providing device 300.

Referring to FIG. 7, when a service search query is input from the user query input unit 110 of the service request device 100 (S210), the registration query unit 210 of the service relay device 200 may store the service storage device 400. The corresponding service provision information is retrieved from the service provision information table 500 of FIG. 3 (S220).

As a result of the search, it is determined whether the service providing information corresponding to the query exists (S230).

If it is determined in step S230 that the service providing information exists, the registration query unit 210 returns the service proxy information included in the searched service providing information to the user query input unit 110 and transmits it (S240). .

On the contrary, if it is determined in step S230 that the service providing information does not exist, the registration query unit 210 waits for the transfer of the service request information from the user query input unit 110 (S250).

When the service request information by the user request is transmitted from the user query input unit 110, the registration query unit 210 transmits the service request information to the service request information table of the service storage device 400 (see FIG. 4). 600) (S260).

Subsequently, the registration query unit 210 stores the interest request stored in the service storage device 400 using the service category 620 and the service keyword 630 of the service request information registered in the service request information table 600 in step S260. The service request information is transmitted to the service management unit 340 of the service providing apparatuses 300, which search the list table 700 (refer to FIG. 5) and register a request for interest in which corresponding service categories coincide with each other and the intersection of service keywords exists. (S270).

By the service relay process, the service relay device 200 may smoothly relay a content service between a service user and a service provider, and in particular, may provide service request information desired by a user to a service provider.

Finally, FIG. 8 is a flowchart illustrating a content service providing process according to an exemplary embodiment of the present invention. The content service providing process is performed by the service providing apparatus 300.

Referring to FIG. 8, the service manager 340 of the service providing apparatus 300 searches for the interest request information registered in the interest request list table 700 of FIG. 5 through the service relay apparatus 200, and retrieves the found interest request. By checking the information, new interest request information is added, unnecessary interest request information is deleted, or existing interest request information is changed (S410).

Thereafter, the service manager 340 compares the interest request list table (700 of FIG. 5) and the service request information table (600 of FIG. 4) stored in the service storage device 400 with the information of the interest request list table. Detecting a matching service request from the service request information table (S420), or receiving newly registered service request information from the registration query unit 210 of the service relay device 200 (S430), or optionally by the service provider The provided list is created (S440).

When any one of the steps S420, S430, and S440 occurs, the service generating unit 310 of the service providing apparatus 300 generates a service providing code according to the searched or inputted service request or created service providing information, and generates the generated service providing code. The registered information about the service providing code is registered in the service storage device 400 through the registration query unit 210 (S440).

In addition, the service manager 340 transmits the service proxy information included in the registered service provision code information to the user query input unit 110 of the service request device 100 that the service request device 100 wants to automatically provide through the registration manager 210. (S450).

According to the service providing process, the service provider may obtain the service information that the user wants and want to provide, and generate and provide an appropriate service through the service provider. In addition, the service relay device may generate the generated service provision information and the service proxy information. The service request apparatus 100 of the user may be provided through the 200.

In the above described and illustrated with respect to certain preferred embodiments of the present invention.
