1 illustrates a system for using a service according to an embodiment of the present invention.

Referring to FIG. 1, a TV 110, a client of a home network domain, accesses the Internet through a gateway 120. The TV 110 may access the Internet through the gateway 120 and the router 130 of the ISP1 (hereinafter, 'Internet service provider' is referred to as 'ISP') network.

However, when the producer of the TV 110 produces the TV 110, it may not know which ISP's network will be connected to use the service. Therefore, in order to enable a user to use the services of one of the plurality of ISPs through the TV 110, all software related to the services of the plurality of ISPs must be provided. In other words, in the example shown in Fig. 1, the TV 10 is not able to know which ISP1 or ISP2 is provided with the Internet connection, so that the producer can access all the ISPs and use the service when producing the TV 110. Widgets, user interface (UI), and other software must all be embedded. This may result in an increase in production costs due to the increase in the capacity of the memory for embedding the software.

In order to solve this problem, a method for selecting a ISP that provides Internet access to the TV 110 from among a plurality of ISPs and a method of using a service is required. For this, the service using system according to the present invention uses a solution hub 140. It is provided separately, and manages information for a plurality of ISP through the solution hub 140.

The solution hub 140 may manage information about a plurality of ISPs, information about servers operated by a plurality of ISPs, and widgets necessary for using services of a plurality of ISPs on the TV 110. The widget is an example of software required to use the services of a plurality of ISPs through the TV 110, and all software that can be installed in the TV 110 to use services of a plurality of ISPs such as a UI and an application. May be managed by the solution hub 140.

Probe servers 150 and 170 are servers for authenticating through which ISP the TV 110 is receiving Internet services. The TV 110 receives information about the probe servers 150 and 170 through the solution hub 140, and then attempts to connect to the probe servers 150 and 170 based on the received information to perform user authentication. do.

In the embodiment shown in FIG. 1, if the TV 110 is provided with an Internet connection from ISP1, the user can connect to the probe server 150 of ISP1 and receive user authentication, and ISP1 can be authenticated through the service server 160 of ISP1. You can use the services provided. However, even if the TV 110 accesses the probe server 170 of ISP2 through the two routers 130 and 132, it cannot access the probe server 170 of ISP2 and receive user authentication, and therefore, the service of ISP2. The service provided by ISP2 cannot be used through the server 160.

FIG. 1 illustrates a case where a probe server and a service server exist as separate entities logically or physically separated for each ISP, but the probe server and the service server may exist as one entity. Those of ordinary skill in the art can easily know. In other words, ISP1 may operate only one server that performs both the function of the probe server 150 and the function of the service server 160, and ISP2 may also operate the function of the probe server 170 and the function of the service server 180. You can even run only one server that does both. In the following description, a case where each ISP operates one server that performs a function of a probe server and a service server will be described as an example. Even if a server exists, it can be easily understood by those skilled in the art that the method of using a service according to the present invention described below can be applied.

2 is a flowchart illustrating a service using method according to an embodiment of the present invention.

Referring to FIG. 2, in step 210, the client 20 accesses the management server 30 to perform device authentication. The client 20 may correspond to the TV 110 of FIG. 1, and the management server 30 may correspond to the solution hub 140 of FIG. 1 as a server managing information on ISP1.

The management server 30 is a server that manages software for using information and services of the server of ISP1 so that the client 20 can use the service of ISP1. Thus, the software may be dependent on the client 20, and the management server 30 may be a server operated by the producer who produced the client 20 to support the use of the service of the client 20.

In this case, the management server 30 allows the client 20 to access information about the probe server of ISP1 from the management server 30 in step 210 so that only the client 20 produced by a specific producer can access the management server 30. Perform device authentication to confirm that the device can receive software. By checking the serial number of the client 20, it is determined whether the client 20 is a device produced by the producer operating the management server 20.

Step 210 is an optional step. If the management server 30 is a general purpose server to which all client devices can connect regardless of the producer, then the device authentication of step 210 is not necessary.

In operation 220, the client 20 receives information about the ISP1 server 40 from the management server 30. The client 20 may request the URL information of the ISP server 40 by accessing the management server 30 based on the URL information of the management server 30 known in advance. When the probe server and the service server are separated as illustrated in FIG. 1, the URL information of the probe server is requested. Request and reception of information to the ISP1 server 40 may be performed according to the hypertext transfer protocol (HTTP) as shown in Table 1 below.

Content-Type: application / x-ispboundservice + xml
Content-Length: 147

<? xml version = '1.0' encoding = 'UTF-8'?>
<ProbeServers>
<ProbeServer> ISP1.probe.com </ ProbeServer>
</ ProbeServers>

Referring to Table 1, the client 20 requests the address of the ISP1 server 40 using the GET method of HTTP. Then, an HTTP response message including the address of the ISP1 server 40 in the body is received from the management server 30.

In operation 230, the client 20 accesses the ISP1 server 40 based on the information about the ISP1 server 40 received in operation 220 to perform user authentication. Check if client 20 is provided with Internet access from ISP1. When the probe server and the service server are separated as shown in the example of FIG. 1, user authentication in step 230 may be performed by the probe server of ISP1.

As described above with reference to FIG. 1, among services provided by ISP1, there may be a service available only to a user who is provided with Internet access from ISP1. Accordingly, user authentication is performed in step 230 to determine whether the client 20 is a device that receives an Internet connection from ISP1.

The client 20 transmits the information about the client 20 to the ISP1 server 40, and ISP1 determines whether the client 20 is a device provided with the Internet connection from the client 20 based on the transmitted information.

The client 20 may transmit an IP address (internet protocol address) to the ISP1 server 40. Since ISP1 knows all of its assigned IP addresses, if the IP address of client 20 is one of its assigned IP addresses, it can authenticate that client 20 is a device that receives Internet access from ISP1. .

In addition, the client 20 may transmit its user ID and Universally Unique Identifier (UUID) to the ISP1 server 40. The user ID may be an ID input when the client 20 logs in to receive an Internet connection from ISP1.

By doing so, the user authentication of step 230 is completed.

Steps 240 and 250 are steps in which the client 20 having completed user authentication in step 230 uses the service of ISP1.

In operation 240, the client 20 receives software necessary for using the service of ISP1 from the management server 30. The client 20 may request the management server 30 for the software necessary to use the service of ISP1, and receive the predetermined software in response to the request. The software may include at least one of a widget, a user interface (UI), and an application required for using the service of ISP1.

If there are a plurality of widgets for using the service of ISP1, the ISP1 server 40 provides the client 20 with a list of the plurality of widgets according to the software request of the client 20, and the client 20 is included in the list. It is possible to sequentially receive a plurality of widgets. Table 2 below shows a list of a plurality of widgets.

Client-> Management Server GET infolink.pavv.co.kr/ GetIspWidgetList? Isp = ISP1.probe.com HTTP / 1.1 Management Server-> Client HTTP / 1.1 200 OK
