2A is an overall configuration diagram of a web page interworking system according to an exemplary embodiment of the present invention.

In general, the Internet is a transmission control protocol between a plurality of network units separated by an Internet Protocol (hereinafter referred to as IP) address and a plurality of hosts having individual IP addresses provided in each unit network. It is based on the Internet Protocol (Transmission Control Protocol / Internet Protocol: hereinafter referred to as TCP / IP). Based on the TCP / IP, a data communication network capable of performing data communication using a local area network (LAN) or a public switched telephone network (PSTN) is called the Internet. Here, the host means a computer having a communication modem, and can communicate with each other only with a unique IP address assigned to each host.

The present invention can link web pages between a plurality of terminals based on the IP address information. The web page interworking method will be described in detail with reference to FIGS. 4 to 6.

2A, a web page interworking system according to an embodiment of the present invention includes a management server 100 and a plurality of terminals 110-1, 110-2, 110-3,... The server 100 and the plurality of terminals 110-1, 110-2, 110-3, ... are coupled through the network 105.

The management server 100 according to the present invention does not perform a direct function in connection with the web page interworking according to the present invention. The management server 100 performs functions such as authentication of a user corresponding to a plurality of terminals, extraction of an IP address of the terminal, and the like.

That is, the management server 100 authenticates the user using an ID and a password, and extracts an IP address corresponding to the user's terminal. The connection state of the user and the extracted IP address are transmitted to a plurality of preset terminals.

Here, the plurality of preset terminals refer to a group set by a user and can be set for various categories such as a friend group, a company group, a school group, and the like. Hereinafter, the group will be collectively referred to as a friend group.

When the plurality of terminals 110-1, 110-2, 110-3, ... are connected to the management server 100 through an authentication procedure, friend groups information and IP address information corresponding to the user of the terminal are displayed. It receives from the management server 100.

After authentication, the plurality of terminals 110-1, 110-2, 110-3, ... can transmit and receive data directly via the IP address without passing through the management server.

The network 105 may include both the basic wired and wireless network as well as include the Internet based on TCP / IP.

Web page interworking between a plurality of terminals (110-1, 110-2, 110-3, ...) according to the present invention is made by using the content, URL information and events based on the document object model (DOM object) .

The Document Object Model (DOM Object) can use HTML pages or XML documents as program objects.

By providing the document based on a document object model (DOM object), the documents can be manipulated like program objects.

Documents, like objects, can have object-oriented procedures called methods. This document object model (DOM object) provides two layers of interface implementation, one is the Document Object Model (DOM Object) that supports XML, which is the foundation of the next layer, and the other is the Document Object Model ( DOM object) HTML, which extends its model into an HTML document.

2B is a flowchart illustrating a terminal authentication processing procedure according to an exemplary embodiment of the present invention, and FIG. 2C is a block diagram illustrating a connection state during terminal authentication according to an exemplary embodiment of the present invention.

According to the present invention, a web page may be linked between a plurality of terminals, but for convenience of explanation of the present invention, only two terminals will be described as an embodiment.

The present invention is different from the individual file-to-person file sharing techniques and behaviors performed on the Internet as in the conventional P2P scheme. According to the existing P2P method, it is not a concept of a server and a client, but directly connects and searches between personal terminals.

However, according to the web page interworking method according to the present invention, any terminal of a personal terminal operates as a server, and a terminal linked to a terminal operating as the server operates as a terminal.

Hereinafter, a subscriber authentication procedure before performing web page interworking according to the present invention will be described with reference to FIGS. 2B and 2C.

In operation 200, the first terminal 250 accesses and logs in to the management server 260.

In operation 205, the management server 260 performs authentication and extracts and stores an IP address corresponding to the first terminal 250. In operation 210, the management server 260 extracts a friend group corresponding to the first terminal 250, and stores the friend group extracted in step 215 and the IP address corresponding to the friend group in the first terminal 250. do. Hereinafter, the friend group and the IP address corresponding to the friend group will be referred to as friend information.

Thereafter, when the second terminal 270 accesses and logs in to the management server 260 in step 220, the management server 260 performs authentication and extracts an IP address corresponding to the second terminal 270 in step 225. Save it.

In operation 230, the management server 260 extracts a friend group corresponding to the second terminal 270 and stores the friend information extracted in step 235 in the second terminal 270.

Here, if the first terminal 250 and the second terminal 270 belong to a friend group, the friend information will be transmitted with the IP address corresponding to the first terminal 250.

In operation 240, the management server 260 transmits friend information including login information of the first terminal 250 and an IP address corresponding to the first terminal 250, to the first terminal 250.

Through the above-described steps 200 to 240, the first terminal 250 and the second terminal 270 perform basic operations on direct data transmission. After extracting the other party's IP address after connection, the first terminal and the second terminal can exchange data directly without passing through the server.

Although the method of sharing the information on the connection state and the IP address between the first terminal 250 and the second terminal 270 through the authentication method of the management server 260 has been described, the IP address in advance between the terminals is described. If you share personal information, such as, can be connected directly without the management server (260).

That is, if the IP address between each terminal is fixed, since the web page can be directly linked without being authenticated by the management server 260, it is natural that the steps described in FIG. 2B are not necessary.

Hereinafter, a case in which web page interworking is performed directly between terminals will be described as the first embodiment, and a case in which web page interworking is performed via a management server will be described as a second embodiment.

In a network environment where web interworking is not possible by P2P method externally due to intranet or internal IP, web interworking is possible by relay of management server.

First embodiment

3A is a flowchart illustrating an overall interworking procedure according to an embodiment of the present invention.

According to the present invention, unlike a conventional P2P scheme, any terminal of a personal terminal operates as a server, and a terminal linked to a terminal operating as the server operates as a terminal.

Hereinafter, a terminal operating as a server will be referred to as a linked server, and a terminal linked to the linked server will be referred to as a linked client.

According to the present invention, all terminals connected to the server can operate as a coordinated server. In addition, the other terminal may be connected to the interlocking server and operate as the interlocking client, and the interlocking client may interoperate with all operations including a web page, an event, and the like, which are performed in the browser of the interlocking server.

Here, an event is a kind of signal that occurs when a special event occurs, for example, when the mouse pointer is over a particular string or image, or when a user opens a browser, another window pops up. .

Hereinafter, a web page interworking procedure according to the present invention will be described with reference to FIG. 3A.

In operation 300, any terminal among a plurality of terminals connected through a network is set as an interworking server. When set as a linked server, web page linked information is transmitted to a linked client linked to the linked server by a preset program.

In step 305, the companion server receives an association request signal from the companion client, and in step 310, determines whether to permit the association. If the association is permitted, the companion server transmits an association permission signal to the companion client in step 315.

Simultaneously with the transmission of the interlocking permission signal, in step 320, the interlocking client interworks with the webpage of the interlocking server, and the interlocking client accesses the site to which the interlocking server is currently connected by using the interlocking information including the site information connected to the interlocking server. Can be.

If the interworking is not permitted, in step 320, the interworking server transmits the interworking disallowed signal to the interworking client, and in this case, a message such as 'no interworking is permitted' may be displayed on the terminal of the interlocking client.

3B is a diagram illustrating an example of a screen configured as a companion server in a terminal according to an exemplary embodiment of the present invention.

According to the present invention, any of a plurality of terminals connected through a network can operate as a coordinated server as well as a coordinated client.

In operation 350, any terminal may operate as an interworking server by clicking buttons corresponding to a menu operating as an interlocking server.

Thereafter, in step 355, the browser is linked to the site by visiting the site, and all the interlocking information including the information such as events occurring on the site is transmitted to the terminal linked to the interlocking information, thereby interlocking the web page. Can be.

Interworking information according to an embodiment of the present invention includes URL information and event information. The URL information refers to an IP address corresponding to a site to which the linked server is currently connected, and the event information refers to a series of operations performed by the linked server at the site, for example, scrolling and clicking.

The method of extracting URL information and event information will be described in detail with reference to FIGS. 4 to 6.

3C is an exemplary view showing a screen to which a web page is linked according to an exemplary embodiment of the present invention.

In step 380, the browser of the linked server is connected to the site A, and the linked client is connected to the B site.

In step 385, when the companion client transmits an interworking request signal to the companion server, and the companion server permits this, the companion client receives the companion information and accesses the A site to which the companion server currently connects.

In step 390, when the linked server moves to the C site, the linked server moves to the C site.

Such web page interworking is performed by extracting interlocking information from the interlocking server and transmitting the interlocking information to the interlocking client currently interlocked.

4 is a flowchart illustrating an initial web page interworking procedure according to an embodiment of the present invention.

The interworking information according to the present invention includes URL information and event information, wherein the URL information refers to an IP address corresponding to a site to which the interworking server is currently connected, and the event information refers to a series of operations performed by the interworking server at the site, For example, scroll, click and so on.

According to an embodiment of the present invention, the interworking information at the time of the first interworking may include only URL information, and the subsequent interworking information may include URL information and event information.

Hereinafter, a web page interworking method will be described with reference to FIG. 4.

In step 400, the server operates as a coordinated server and the terminal drives a browser. When the browser starts up, it connects to the site set as the default page of the browser.

In step 405, the companion server receives a webpage interworking request signal from the companion client. A case where the interworking server receiving the interworking request signal permits interworking will be described below.

In step 410, the companion server extracts URL information of the currently accessed site, and transmits a linkage permission signal including the extracted URL information to the companion terminal. Thereafter, by transmitting the URL information and the event information of the companion server to the companion terminal in real time, the companion terminal operates in conjunction with the companion server.

In step 420, the companion client accesses a site corresponding to the URL information by using the received URL information and interworks with the companion server.

In operation 425, the companion server extracts event object information when an event occurs. The URL information of the web page where the event occurred is extracted.

According to the present invention, even when an event occurs, URL information is included and transmitted. Therefore, even when the coordinated client accesses a site different from the site to which the coordinated server is connected, the coordinated client can operate in conjunction with the event.

In step 435, the companion server transmits URL information and event object information to the companion client. In step 440, the companion server interlocks the event using the received URL information and the event object information.

According to the present invention, the coordinated client compares the URL information received from the coordinated server with the coordinated client current URL information when the event is interlocked. As a result of the comparison, when both URL information is the same, the event may be linked. If not, the event may be linked after accessing a site corresponding to the URL information received from the companion server.

That is, when the URL is not the same, it is preferable to go to a site connected to the linked server, download all the contents, and then link the events. The event interworking method will be described below with reference to FIGS. 5 to 6C.

5 is a flowchart illustrating a web page interworking procedure when a click event occurs according to an exemplary embodiment of the present invention.

An event refers to a signal that a particular action has occurred. For example, everything that can happen in a browser is an event, such as when a button is clicked, when a mouse passes over a hypertext link, or when a new document is downloaded from the browser.

Hereinafter, with reference to FIG. 5, a description will be given on the basis of a linkage method when a click event occurs for convenience of description when linking an event. However, the present invention is not limited to the click event, it is natural that all events can be linked using the same algorithm.

In step 500, the interlocking server detects a click event when any element of the web page is clicked. In operation 505, the companion server extracts an index of the clicked object to generate event information.

In step 510, the companion server extracts URL information of the currently accessed site. In operation 515, the interworking server generates an event interworking signal including URL information and event information. In operation 520, the interworking server transmits the generated event interworking signal to the interworking client.

In operation 525, when the companion client receives the event association signal, the companion client first extracts URL information of a site that the companion client currently accesses. In operation 530, the companion client compares URL information included in the received event companion signal with URL information corresponding to a site to which the companion client currently accesses.

As a result of the comparison, when the URL information included in the received event interlocking signal and the URL information corresponding to the site currently connected to the interlocking client are different, in step 540, the interlocking client corresponds to a site corresponding to the URL information included in the received event interlocking signal. Connect to

In operation 535, the companion client extracts the received event information, in this case, the index corresponding to the object corresponding to the click, and generates a click event on the object corresponding to the index.

6A is a flowchart illustrating interlocking preconditions according to an exemplary embodiment of the present invention.

According to the present invention, after the linked client accesses a URL corresponding to a site connected by the linked server, it is preferable to determine whether the download of the page is completed, and it is preferable to link the event after the download of the page is completed.

Referring to FIG. 6A, a flowchart of connecting to a document object model (DOM object) is shown after completion of page download according to an exemplary embodiment of the present invention.

In operation 600, the companion client determines whether the download of the page is completed. When the download of the page is completed, the companion client connects to the document object model (DOM object) of the downloaded page in operation 605.

The download speed of a web page may be different due to differences in transmission speeds and loads of a network corresponding to the companion server and the companion client. In such a case, it is preferable to match the URL of the currently connected site before the event is interlocked when an event of the interlocking server occurs. In the case of matching the URL, it is preferable to match the web page after the download of the web page is completed.

6B is a block diagram illustrating a structure of a document object model (DOM object) according to an exemplary embodiment of the present invention.

The Document Object Model (DOM Object) displays an XML document in a tree structure. The top level object is the root of the tree and has one top level element. These elements can have child nodes that represent content, or child elements that can have additional children. Functions can add and remove nodes by traversing the result tree or by accessing element and attribute values.

By using this document object model (DOM object), you can create a document object model (DOM object) tree, add new nodes or move subtrees, and then output the results as a new XML document, thereby modifying the XML document. Make it easy

According to the present invention, an index of an element may be extracted when an event occurs using such a document object model (DOM object), and an element corresponding to the index may generate the same event as that generated by the coordinated server.

Referring to FIG. 6B, a WINDOW object 620, a DOCUMENT object 625, a LOCATION object 630, an HREF object 635, an EVENT object 640, an ELEMENT object 645, an INDEX 650 object, and the like are illustrated. It is.

The DOCUMENT object 625 represents an entire HTML document and serves as a container for all HTML related objects associated with <head> and <body> tags. The properties of this object include bgColor, fgColor, forms, alinkColor, links, title, and linkColor.

The LOCATION object 630 is automatically created when the window is opened. It's possible. The LOCATION object 630 is an object that provides information about the URL of an HTML document open in the current browser window.

The HREF object 635 is an object that provides information about the full URL of the currently accessed site. The EVENT object 640 is an object that detects an event when an event occurs and performs a preset operation corresponding to the event.

When a click event occurs according to an embodiment of the present invention, the EVENT object 640 detects a click and performs a click event on the clicked element.

The ELEMENT object 645 is an object that provides information about the clicked element, and the INDEX 650 object is an object that provides an index by the document object model of the clicked element. The INDEX 650 object provides an index of any element, and an offset may be specified relative to the head of the document.

The document object model seeks to streamline programming by dividing a given problem into several related modules called objects. According to the present invention, the coordinated server extracts URL information and index information corresponding to the clicked element by using a DOM object, and transmits the extracted URL information and index information, and the coordinated client receives the received URL information and index information. By extracting the clicked element and generating a click event to the element, the event can be linked.

6C is a flowchart illustrating a linking procedure when a click event occurs according to an exemplary embodiment of the present invention.

According to the present invention, all events of the interlocking server can be detected, and the interlocking client can be interlocked according to the event, but for convenience of explanation, the operation method of the click event will be described as an embodiment. do.

In operation 670, when the click event occurs, the companion server detects the click event and executes the event by using an event handler corresponding to the click event. The event handler performs an operation corresponding to the event whenever an event occurs, and executes an event when a click event that a button is pressed according to an embodiment of the present invention occurs.

If the click event occurs in step 675, the interworking server searches for a WINDOW object and extracts a WINDOW object and a DOCUMENT object in step 680.

In operation 680, the coordinated server extracts a LOCATION object, and in step 683, the coordinated server extracts URL information of the current web page.

In step 686, the interworking server obtains an event object and in step 690 extracts an element corresponding to the event. In step 693, the coordinated server extracts an index corresponding to the element.

Via the above-described steps 670 to 693, the index interworking signal may be generated by extracting URL information corresponding to the site currently connected to the interworking server and index information of the element in which the event has occurred.

Thereafter, the index interworking signal is transmitted to the interlocking client, and the interlocking client interlocks the event using the URL information and the index information included in the index interworking signal.

After completing the connection and login, in step 700 any terminal of the plurality of terminals connected via the network is set as a coordinated server. In step 705, the companion server transmits a companion server setting signal to the companion relay server.

The interworking relay server that receives the interworking server setting signal in step 710 stores an IP address corresponding to the interworking server.

When the interworking relay server receives the interlocking request signal from the interlocking client in step 715, the interlocking relay server extracts the IP address of the interlocking server in step 310, and transmits the IP address of the interlocking server extracted to the interlocking client in step 725.

In operation 730, the companion client transmits a linkage request signal to the linked server using the IP address of the linked server.

In step 735, the companion server receiving the interworking request signal determines whether to permit the interworking interworking. If the linkage is permitted, the linkage server transmits a linkage permission signal to the linkage relay server in step 740.

In step 750, the interlocking relay server extracts IP address information of the interlocking client corresponding to the interworking permission signal, and transmits the interworking permission signal to the interworking client in step 755.

In operation 760, the interlocking client interworks with the webpage of the interlocking server, and the interlocking client may access a site to which the interlocking server is currently connected by using the interlocking information including site information to which the interlocking server is connected.

If the interworking is not permitted, the interworking server transmits a linking disallowed signal to the interlocking client, and in this case, a message such as 'no linking is permitted' may be displayed on the terminal of the interlocking client.

In FIG. 7, a method of interworking a web page through an interworking relay server has been described mainly. However, a method of interlocking events may be performed by a method similar to the above-described web page interworking method.

According to the second embodiment of the present invention, even if web interworking is performed by the interlocking relay server, since the information transmitted and received with the interworking terminal is URL information or event information, the processing speed or load of the interlocking relay server is not a problem.

As described above, according to the present invention, there is an effect that a web page can be displayed by interlocking a plurality of terminals.

In addition, the present invention can also be linked to a web page at the same time connected to the site connected to the user connected to the terminal, and a series of actions performed on the site, for example, clicks, file downloads, etc. can also be performed have.

In addition, the present invention has the effect that it is possible to monitor in real time the site connected from the terminal of the other person through a web interlocking program.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
