Method and System for Providing Contents Clipping Service for PDA by Using Wireless Network using Wireless Communication Network

The present invention relates to a method and system for providing a real-time content clipping service to a PD using a wireless communication network. More specifically, a user collects and registers content clipped to a wired web site using a computer and registers a specific clip from a user's personal digital assistant (PDA). The present invention relates to a method and system for providing a content clipping service which processes a registered content so that it can be played on a user's PDA when the transmission is requested.

Recently, with the rapid development of electronic engineering, communication engineering, and terminal technology, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice calls but also wireless Internet access, video communication and video message transmission using mobile communication terminals.

However, while a mobile communication terminal represented by a mobile phone has a feature of overcoming fixedness, which is the biggest disadvantage of a personal computer (PC), guarantees the mobility of a user, there are also various disadvantages. In other words, the performance of the CPU and the storage capacity of the CPU are greatly limited by the lightweight and compact design to guarantee the mobility of the user, and free data input by the structure of the narrow key matrix. This has the disadvantage of being difficult. In addition, the LCD (Liquid Crystal Display) screen is also small, so a lot of information cannot be displayed on one screen, and the attached battery is also limited in size, which greatly limits the amount of time the mobile phone can be used continuously without recharging the battery. There are disadvantages.

Recently, a mobile communication device that has been spotlighted as a leader in post PCs by overcoming the shortcomings of such mobile phones is a PDA. PDA is a kind of portable computer. It is possible to work while storing and moving document files made by computer fixed at home or office, and portable personal who can manage personal information (PIM) or schedule like electronic notebook. Refers to an information terminal. In the early days of the PDA, it only performed the functions of the high-end electronic organizer, but the advanced PDA specification and the combination with the Code Division Multiple Access (CDMA) module (wireless modem) enable various multimedia functions and wireless. It is evolving into a high-end mobile terminal with Internet function.

However, the number of web sites dedicated to PDAs and the amount of information available through the wireless Internet network are so small that they cannot be compared with wired web sites using personal computers. . Therefore, a method and software that can conveniently use various contents registered in a wired web site in a PDA have been developed, spread, and used.

1 is a block diagram schematically illustrating a system for using contents registered in a wired web site with a conventional PDA.

A system for receiving contents registered in a wired web site using a conventional PDA includes a user computer 110, a PDA 120, the Internet 130, and a plurality of clipping web servers 140 to 150. Here, the user computer 110 is equipped with a predetermined clipping software for clipping the content registered in the wired web site to the clip and store it on the hard disk. Here, the clip refers to a file which reconstructs the content registered in the web page so as to be suitable for the PDA environment while preserving the characteristics of the web page linked by the hyperlink.

Referring to the process of using the content registered in the wired web site with the PDA in the system shown in Figure 1 as follows. First, a user drives a web browser of the user computer 110 to access the clipping web servers 140 to 150 through the Internet 130 to register contents, such as a web document or an image, on a website. Browse. The user runs some clipping software installed on the user computer 110 to clip the specific content being viewed. Then, set the area of the content that you want to clip using a peripheral device such as a mouse, and then select a clipping function supported by the clipping software.

When a clipping command for a specific content area is input by a user, the clipping software reconstructs the corresponding content so as to be suitable for the PDA environment, and when the reconstruction is completed, the clipping software stores the clip file as a clip file on the hard disk.

Then, the user connects the user computer 110 and the PDA 120 using a universal serial bus (USB) cable or the like, and then selects and stores one or more clip files that the user wants to save to the PDA 120. The data synchronization task between the user computer 110 and the PDA 120 is called a sync. When the sync operation is completed, the user can perform operations such as playing, editing, or deleting a clip file stored in the PDA 120.

However, a service that can use contents registered in a wired web site using a PDA described in FIG. 1 has the following disadvantages. First, as described above, in order to use a clip file clipped and stored with a computer on a PDA, it is cumbersome that a sync operation for synchronizing data must be performed after connecting the computer and the PDA with a cable.

Second, there is a disadvantage that a separate playback program is required to play the clip stored in the PDA. In other words, while clipping the content to a computer, the clipping software reconstructs the content to suit the PDA environment, but the reconstructed clip file does not support all PDA devices. Therefore, the user has a disadvantage in that he has to perform a cumbersome task of installing a separate playback program for playing a clip file on his own PDA.

In order to solve the above problems, the present invention collects and registers content clipped from a wired web site using a computer, and registers the corresponding registered content when a specific clip is transmitted from the user's PDA. An object of the present invention is to provide a method and system for providing a content clipping service which is processed to be reproduced in a real time and provided in real time.

In addition, the user can basically play the received clip in real time using the built-in web browser without installing a separate playback program for playing the clipped content (hereinafter referred to as 'clip') transmitted to his PDA. Can be.

The user computer 210 connects to any web server including the clipping web server 220 and accesses an Internet with a web browser installed to perform a function of requesting clipping of a specific content among a plurality of contents registered in the web page. This is possible wired terminal device. In particular, the web browser installed on the user computer 210 should be able to support the Active X function. Here, Active X is an integrated platform technology that integrates the PC platform developed by Microsoft with the wired and wireless Internet. Active X uses existing component software, script languages, and applications to show images, 3D virtual reality, and video on a web page in real time, as well as general application software on the Internet. It is naturally implemented.

Meanwhile, the user computer 210 is provided with a predetermined clip component 212 for clipping desired content. The clip component 212 not only supports clipping of content selected by a user on a web page, but also functions to classify and store clipped content, that is, a plurality of clip pages by clip type, or edit a clip page. To provide. Here, the clip page refers to a document containing one or more clips.

The clip component 212 according to an embodiment of the present invention is a program coded and compiled using Active X technology, which is a kind of Active X control. Here, a control is a reusable object that includes visual elements and code. Using a control can quickly create various forms and dialog boxes. Similarly, the Active X control is a control created by Active X technology. When a user such as a computer accesses a web page that uses the Active X control, the web browser automatically downloads the active X control and installs (executes) and uses it.

When the clip component 212, which is a kind of Active X control according to an embodiment of the present invention, is installed in detail in a user computer 210, the Internet Explorer driven in the user computer 210 will be described. A web browser such as the like connects to the clipping web server 220. The web browser of the user computer 210 reads tag information of the HTML document of the accessed web site and determines whether the web site uses an Active X control and which Active X control is used.

If it is determined that the Active X control is used, the web browser reads the registry information of the user's computer 210 system, and if the Active X control used by the clipping web server 130 is not yet installed, Read the path of the Active X control recorded in the Object tag of the HTML document. Then, it automatically downloads and installs the Active X control stored in the path.

When the clip component 212 is installed on the user computer 210, the clip component 212 is installed in an add-in form in a web browser, and is displayed as an icon in a predetermined area of a driving screen of the web browser. Therefore, when a user clicks a clip component icon included in a web browser with a mouse, the clip component is executed to perform clipping of desired content.

The clipping web server 220 not only operates a web site but also automatically transmits a clip component 212 stored in the connecting user computer 210. In addition, the clipping web server 220 receives the clip information generated by the clip component 212 installed in the user computer 210 by performing a clipping operation on an arbitrary web server through the Internet 130.

Here, the clip information includes URL (Uniform Resource Locator) address information of the web site where the clipping target content is registered, location information in the web document (web page) of the clipping content, and the like. In addition, the clip component 212 provides a separate login screen to the user computer when the clipping target content is a content that requires a user ID and a password to look up the corresponding content such as an email. The user provided with the login screen inputs a user ID and password for viewing content such as an e-mail, and the clip component transmits the received user ID and password to the clipping web server 220 together with the clip information.

Meanwhile, the clipping web server 220 classifies clip information received from the clip component 212 for each user and stores the clip information in the database server 230. Accordingly, the clip component 212 may desirably transmit user information to classify the user to the clipping web server 220. That is, the clip component 212 checks whether the user computer 210 is logged in to the clipping web server 220 when driving is instructed by the user to transmit user information.

If it is determined that the user is not logged in, the clip component 212 provides a membership screen to the user computer 210 before providing the clipping function. That is, the clipping web server 220 classifies a plurality of clip information received from the user computer 210 based on user information, such as a user ID received from a login screen or a member registration screen, together with clip information. ).

Meanwhile, in the process of joining the clipping web server 220 as a member, the user must input PDA model information to use the content clipping service. Here, the PDA model information refers to information such as the name of the PDA 240, the manufacturer, and a mounted operating system. The input of PDA information is used in the step of converting clip data performed by the clipping service server 280 to be described later.

The database server 230 receives and stores the user information received in the joining step of the clipping web server 220 that provides the content clipping service from the clipping web server 220. Here, the user information includes essential input information such as identification (ID), password, and PDA information. In addition, the database server 230 classifies and stores clip information transmitted from the clip component 212 installed in the user computer 210 by user ID under the control of the clipping web server 220. In addition, the database server 230 may divide and store clip information stored for each user ID for each of a plurality of categories.

The PDA 240 is a mobile terminal that performs a function of receiving and playing clipped content, that is, a clip, through a mobile communication network, according to an exemplary embodiment of the present invention. The PDA 240 is provided with a wireless modem and a web browser for a PDA with a built-in CDMA module for receiving and playing back clip data through a mobile communication network. Of course, the wireless modem embedded in the PDA 240 may support a mobile communication protocol to be used in the fourth generation ALL-IP network, which is a global standard for mobile (GSM) module and a next generation communication network, in addition to the CDMA module. In addition, the PDA 240 may reproduce clip data received through a mobile communication network in real time using a PDA web browser installed for each model without a separate playback program.

The radio access network 250 includes a base station transmitter 252 and a base station controller 254 and supports both synchronous and asynchronous mobile communication systems. Here, in the synchronous mobile communication system, the base station transmitter 252 is a base transceiver station (BTS), the base station controller 254 is a base station controller (BSC), and in the case of an asynchronous mobile communication system, the base station transmitter 252 is a RTS (Radio). The base station controller 254 is a radio network controller (RNC). Of course, the wireless access network 250 according to an embodiment of the present invention is not limited to the CDMA network, but may include a GSM network and an access network of a fourth generation mobile communication system to be implemented in the future.

The base station transmitter 252 receives the clip transmission request signal from the PDA 240 through the traffic channel of the signal channel and transmits it to the base station controller 254. The base station controller 254 controls the base station transmitter 252, assigns and releases radio channels to the PDA 240, controls the transmission output of the PDA 240 and the base station transmitter 252, and soft handoff between cells. And hard handoff determination. The base station controller 254 transmits the clip transmission request signal received through the base station transmitter 252 to the mobile switching center 260.

The mobile switching center (MSC) 260 is equipped with a plurality of exchanges to perform basic and additional service processing, incoming and outgoing call processing of subscribers, location registration and handoff procedures, and interworking with other networks. do. The mobile switching center 260 according to the embodiment of the present invention supports both an Interim Standard (IS) -95 A / B / C system and a third generation and fourth generation mobile communication network. To this end, the mobile switching center 260 may include an access switching subsystem (ASS) that performs distributed call processing, an INS (interconnection network subsystem) that performs centralized call processing, and a centralized CCS (operation and maintenance). It includes a subsystem such as a Central Control Subsystem (LOC), a Location Registration Subsystem (RLS) that performs storage and management of information on mobile subscribers. In addition, the mobile switching center 260 may include an Asynchronous Transfer Mode (ATM) switch (not shown) in order to increase data transmission rate and efficiency of line use by transmitting data in a cell-based packet manner. have.

The wireless gateway 270 switches circuit lines and data lines on a cell-by-cell basis to process interworking function (IWF) conversion functions used in a mobile communication system and packet data directly connected on a cell-by-cell basis. do.

Meanwhile, the wireless gateway 270 may include a WAP gateway, which functions to convert text file data on the Internet into a binary code structure. That is, the WAP gateway receives an Internet service request from the PDA 240 by the WAP protocol, converts the WAP gateway into a Transmission Control Protocol / Internet Protocol (TCP / IP) protocol, and transmits it to the clipping service server 280. On the contrary, the response data received from the clipping service server 280 by the TCP / IP protocol is received, converted into the WAP protocol, and transmitted to the PDA 240.

The clipping service server 280 receives the clip transmission request signal from the PDA 240 through the mobile communication network and the wireless Internet network, and transmits the requested clip to the PDA 240 through a predetermined data conversion operation. That is, the clipping service server 280 performs authentication of the PDA 240 user who accesses it via the mobile communication network and the wireless Internet network, and uses the user ID received from the PDA 240 in the user authentication process. The clip list of the user stored in the database server 230 is retrieved. Then, the searched clip list screen is provided to the PDA 240 through the mobile communication network and the wireless Internet network.

On the other hand, when the clipping service server 280 receives the clip transmission request signal from the PDA 240, the mobile station identification number (MIN: Mobile Identification Number, hereinafter referred to as 'MIN') of the PDA 240 included in the clip transmission request signal. The user may also search for a clip list of the user stored in the database server 230. In order to retrieve the list of clips stored in the database server 230 using the MIN of the PDA 240, the MIN of the PDA 240 should be input as user information at the subscription stage of the content clipping service.

Meanwhile, the clipping service server 280 accesses the web site using the URL address included in the clip information of the specific clip requested from the PDA 240. In addition, the clipping service server 280 identifies and collects the corresponding content from the accessed web site using the location information of the content in the web document included in the clip information.

The clipping service server 280 includes a clip converter 282, which converts the data format of the web content so that the requested web content can be played on the user's PDA 240. Here, the conversion of the web content performed by the clip converter 282 is performed for each type of user PDA. Therefore, the clipping service server 280 performs the operation of identifying the type information of the PDA included in the information of the user stored in the database server 230 using the login ID of the user who requested the transmission of the web content. Then, when the model information of the identified PDA is provided to the clip converter 282, the clip converter 282 performs the conversion of the web content so as to conform to the received model information.

Meanwhile, the clip converter 282 includes a plurality of PDA type conversion information for converting web content to be suitable for the PDA 240 of the user using the type information received from the clipping service server 280. Here, the conversion information for each PDA model is PocketPC, Palm, Cellvic, Linux, Psion, Newton Notepad, Cassiopeia, Sigma, and other series.

For example, Cassiopeia uses Window CE, Selvik uses Zeltel's own Cellvik OS, Palm also develops its own Palm OS, Cyan uses EPOC OS, and Sigma uses Linux and Java based OS. Since PDAs have different basic and application applications according to operating systems, it is necessary to convert data formats according to operating systems. Also, the screen size is variously used such as 160 × 160, 240 × 320, 240 × 340, 320 × 320, 640 × 240, and the supported colors are black and white, 4 colors, 16 colors, 256 colors, 65,000 colors, etc. It is becoming.

3 is a flowchart illustrating a process of clipping web content using a clip component 212 according to an embodiment of the present invention.

In the detailed description of FIG. 3, it is assumed that the clip component 212 is already installed in the web browser of the user computer 210. A user who wants to use a clipping service of web content according to an embodiment of the present invention drives a web browser installed in the user computer 210 (S300). The user selects an arbitrary position of the driven web browser, for example, a clip component icon included at the top of the web browser by a mouse click or the like (S302).

When the clip component icon is selected, the clip component is driven to check whether the user computer 210 is logged in to the clipping web server 220 (S304). If it is determined in step S304 that the user computer 210 is not logged in to the clipping web server 220, the clip component provides a login screen or a member registration screen to the user computer 210 to perform a login procedure. Otherwise, if it is determined that the user computer 210 is logged in to the clipping web server 220, the clip component is activated to allow the user to perform clipping of the web content (S308).

When the clip component 212 is activated, a content area, such as a quadrangle, is set along the movement path of the mouse pointer (S310). The clip component 212 continuously checks whether a command for completing the content area setting operation is input while the content area setting operation is performed in step S310 (S312). If it is determined in step S312 that the setting operation of the content area is completed, the clip component 212 stores information (= clip information) regarding the set content area (S314).

The clip component 212 transmits the clip information stored in step S314 to the clipping web server 220 via the Internet 130. Here, the clip information transmitted by the clip component 212 includes a URL address of a web site where the clipped content is registered and location information of the clipped content in the web page or the web document.

Meanwhile, the clip component 212 that performs the clipping operation of the web content continuously checks whether a driving stop command is input (S318). If it is determined in step S318 that the driving stop command is input, the clip component 212 deactivates the clip component (S320). Here, the command for stopping driving of the driving clip component 212 may be input by selecting again the clip component 212 included in the web browser with a mouse or the like.

A user who has completed the clipping operation of one or more web contents through the process described with reference to FIG. 3 accesses the clipping service server 280 using the PDA 240 (S400). Of course, the PDA 240 may not be directly connected to the clipping service server 280, but may be connected to the clipping service server 280 via the clipping web server 220. In this case, the clipping web server 220 will have to operate a web site dedicated to the PDA.

The clipping service server 280 receives a PDA received through a user ID or a mobile switching network and a wireless Internet network input during the connection to the clipping service server 280 to provide a clip list screen of the user to the connected PDA 240. The MIN of 240 is inquired (S402).

The clipping service server 280 retrieves the clip list of the user stored in the database server 230 using the user ID or the MIN inquired in step S402, and transmits the retrieved clip list to the PDA 240 (S404). The clipping service server 280 receives selection information of a particular clip from the PDA 240 of the user and retrieves corresponding clip information stored in the database server 230 (S406). The clipping service server 280 accesses the web site using URL address information in which one or more web contents included in the retrieved clip information are registered (S408). Then, the respective web contents are collected using the web document of the one or more web contents included in the searched clip information or the location information in the web page (S410).

The clipping service server 282 collecting one or more web contents included in the requested clip searches for model information of the connected PDA 240 stored in the database server 230 (S412). The clipping service server 280 grasping the model information of the connected PDA 240 converts the web content collected according to the model of the PDA 240 into data for the PDA using the clip converter 282 (S414). The clipping service server 280 transmits the web content converted in step S414 to the PDA 240 via the wireless Internet network and the mobile communication network (S416). The PDA 418, which receives the clipping content through the wireless Internet network and the mobile communication network, reproduces the received clipping content using a running web browser, without having to run a separate replay program (S418).

When the clip component 212 is driven by performing the login process or driving the clip component 212 while already logged in to the clipping web server 220, the clipping start notification window 600 as shown in FIG. 6A is popped up. . The user may click the OK button of the clipping start notification window 600 to start clipping of the web content. When the clipping operation starts, the clip component 212 checks an area where the mouse pointer moves and recognizes the clipping area 610. In other words, when the user clicks on the first point (first click point) of the region to be clipped and moves the mouse to click on the last point (second click point) of the clipping region, the user forms the first point and the last point. The rectangular area is set as the clipping area 610.

Meanwhile, when the user clicks the last point in the clipping area setting process, the clipping menu window 620 as shown in FIG. 6B pops up. As a menu provided in the clipping menu window 620 according to an embodiment of the present invention, 'Stop Clipping', 'Save Clip', 'Close Menu (ESC)', 'Refresh Clip List', There are 'editing clips', 'editing pages', 'to home page' and 'help'.
