1 illustrates a configuration of a system for searching and providing a file stored in a computer device using a mobile communication terminal according to the present invention. As shown in FIG.

First, the agent 12 performs a search for a file stored in the user computer device 13 according to the present invention and is installed and driven in the mobile communication terminal 11 of a user who wants to receive the file. It performs a signal and data transmission and reception through a direct connection with the search engine 14 through, and outputs the data provided from the search engine on the screen of the mobile communication terminal.

In other words, the agent outputs a file search screen on the mobile communication terminal screen that can be linked with a search engine to search for files stored in the user's computer device, and provides an input window to request a search for a specific file. A search keyword for the corresponding file is input and file data corresponding to the input search keyword is received through communication with a search engine and output on the screen of the mobile communication terminal. In this case, the agent may be connected to an external storage medium to store a file or data provided from a search engine.

The agent can be downloaded and installed from a provider server that provides it through a wireless Internet connection through a wireless Internet browser mounted in a mobile communication terminal or a wired Internet connection using an external communication device.

The search engine 14 is installed in the user computer device 13 to perform a function of searching for a file stored in the user computer device and providing a specific file requested from a user. More specifically, the agent 12 receives a search keyword requesting a search for a specific file stored in the user computer device, performs a search for a file in the user computer device according to the search keyword, and extracts the result as a result. Alternatively, a plurality of files are provided to the agent in the form of a list. After that, if a request for providing a specific file is input from the agent, the file is extracted and provided. Referring to the search engine that performs the above role in more detail as shown in FIG.

2 illustrates each component constituting the search engine according to the present invention. When the components are described by function, first, the communication interface 22 includes an agent 12 installed in a mobile communication terminal and a search engine. It plays a role of mediating connection with (14) so that signals and data can be transmitted and received through communication between the agent and the search engine. The index generator 12 generates an index, and serves to generate an index for each file in advance so that a faster search can be performed when searching for a file stored in the user computer device.

 At this time, the generated index is stored in the index storage unit 24, and then a search can be performed based on the index stored in the index storage unit when the agent requests a search. As a result of the file search by the search processing unit, one or more files are extracted. In this case, the extracted search file must be converted into an appropriate form for transmission to the agent. That is, a file extracted as a search result for output on a mobile communication terminal having a different implementation environment from that of a search engine should be converted, and the conversion process is performed by the conversion unit 26 of the search engine.

As described above, the search engine includes a communication interface 22, an index generator 23, an index storage 24, a search processor 25, and a converter 26, and operation of these components. In order to control the control unit 21 should be configured together.

The registration server 15 receives the corresponding mobile communication terminal information and the user computer device 13 information of the agent 12 and performs registration management on the corresponding information, and the IP address value allocated to the communication connection of the user computer device. The IP address value extraction of the user computer device is performed through the mapping procedure of the corresponding mobile communication terminal information of the pre-registered agent and the corresponding user computer device after the request from the agent. By providing the IP address value of the user computer device to the agent, the agent can directly access the search engine in the user computer device based on the IP address value.

Here, the IP address value of the user computer device is a floating IP address value so that the user computer device is assigned an IP address value having a new value every time a communication connection is made. This means that the agent needs to know the IP address value that is changed every time the user computer device communicates with the search engine.

At this time, the registration server receives and registers an IP address value of the user computer device which is changed every time the communication is connected through a search engine, and performs mapping processing between the user computer device and the corresponding mobile communication terminal according to the change of the IP address value. Therefore, when the agent requests, it can extract and provide an appropriate IP address value for the search engine access. In addition, the registration server may directly distribute an agent and a search engine. That is, a search for a file stored in a user computer device according to the present invention and a user who wants to receive the file access the registration server to join a member. If a specific procedure such as the above is performed, as a result, an agent and a search engine may be provided to the user's mobile communication terminal and the user computer device, respectively.

As described above, the system for searching and providing files stored in the computer device using the mobile communication terminal includes an agent 12 installed in the mobile communication terminal 11, a search engine 13 in the user computer device, and a registration server 14. The method for searching and providing files stored in the computer device using the mobile communication terminal according to the present invention using the system will be described with reference to FIG. 3.

3 is a flowchart illustrating a method for searching and providing a file stored in a user computer device using a mobile communication terminal. Referring to FIG. 3, first, a search for a file stored in a user computer device is performed using a mobile communication terminal. In order to be provided, the user must register the user information with the registration server (S10). That is, the user registers the mobile communication terminal information and the user computer device information in the registration server, for example, the mobile communication terminal number and the user computer device number. The registration server receiving the corresponding information from the user performs a registration procedure for the input information.

When the registration of information about the user's mobile terminal and the user's computer device is completed, the user searches for a file stored in the computer device using the mobile terminal and communicates between the mobile terminal and the user's computer device to receive the file. A search engine capable of processing the operation is installed in the mobile communication terminal and the user computer device (S20).

More specifically, the registration server receives user information from a user and completes registration of the information, and provides an agent and a search engine to the mobile communication terminal and the user computer device of the user, respectively. The user downloads the agent and search engine provided by the registration server and installs them in the mobile communication terminal and the user computer device, respectively. At this time, the installed search engine performs an operation of indexing files stored in the user computer device after installation. do. It will be desirable to allow subsequent indexing to be done at the user's indexing request or periodically.

The user computer device is assigned a new IP address every time a communication connection is made. In other words, once assigned IP address cannot be used consecutively. The IP address of the user's computer device is required for communication between the agent and the search engine, and the management of the changed IP address of the user's computer device is necessary due to the characteristics of the user's computer device that is assigned a changed IP address every time the communication is connected. Do.

The search engine installed in the user computer device transmits the IP address value assigned to the registration server for each communication connection of the user computer device, so that the IP address value of the corresponding user computer device that the agent can access the search engine can be registered ( S30). Specifically, at the time of communication connection of the user computer device, that is, whenever the user computer device is assigned a new IP address value, the search engine transmits the IP address value to the registration server. The registration server receiving the IP address value registers by changing the previous IP address value of the user computer device stored in the IP address value area of the corresponding user computer device to the received current IP address value.

When the installation of the search engine of the agent and the user computer device in the mobile communication terminal is completed through the above process, and registration of the accessible IP address value to the search engine is completed, the user computer using the mobile communication terminal according to the present invention. You are ready to search for and save files on the device.

In order to retrieve and provide a file stored in the computer device using the mobile communication terminal, the user drives an agent to perform a connection connection with a search engine (S40). More specifically, the user runs an agent that is already installed in the mobile communication terminal, and requests the IP address value of the corresponding user computer device for the connection connection with the search engine to the registration server. Upon receiving the request for the IP address value from the agent, the registration server extracts the IP address value of the currently accessible user computer device by performing a mapping procedure with the corresponding user computer device information based on the corresponding mobile terminal information of the agent. And send it to the agent. Upon receiving the IP address value of the user computer device from the registration server, the agent performs the connection connection to the user computer device through the IP address value, and as a result, can communicate with the search engine of the user computer device. .

When the connection is made between the agent and the search engine of the user computer device, the agent performs a search for a file stored in the user computer device through communication with the search engine (S50). After the agent connects to the user computer device and connects to the search engine, the agent outputs a screen for searching for files stored in the user computer device on the screen of the mobile communication terminal as shown in FIG. 4.

That is, an input window is displayed on the screen of the mobile communication terminal so that a user can input a search keyword for searching. The user inputs a search keyword to search for in an input window provided on the screen of the mobile communication terminal, and the agent transmits the input search keyword to a search engine connected through a wireless communication network. Here, the search engine receiving the search keyword from the agent searches whether there is a file having the search keyword in the user computer device based on the search keyword, and provides the agent with a list of extracted search files as a result.

The search operation by the search engine will be described in more detail as follows. When a search keyword is input from the agent, the search engine analyzes the search keyword and performs a comparison procedure with a pre-generated index to extract an index corresponding to the search keyword. The search engine performs a search on the files stored in the user's computer device based on the extracted index. In this case, the file search is not limited to a file name, but includes a file type and a file content.

As a result of the search, one or more files identified by the corresponding index are extracted and this is generated in the form of a search file list. The search engine converts the search file list obtained as a search result into a specific form so that the search file list can be transmitted to the connected agent through the wireless communication network. That is, the search file list is converted into a form suitable for the environment so that the search result data can be output without error in a mobile communication terminal having a different implementation environment from that of the user computer device.

The search file list converted through the above process is transmitted to the agent, and the agent outputs the search file list obtained as a result of the search request on the screen of the mobile communication terminal. This is as shown in Figure 5, where the output for the search file list is typically the same as the result obtained as a file search result in the user computer device. However, in view of a mobile communication terminal environment where a display screen is relatively small, the search file list displayed may be in a downsized form in which a result output in an actual user computer device is output.

As a result of the search, when a list of search files extracted through the input search keyword is displayed on the screen of the mobile communication terminal, the user selects and inputs any one of the search file lists to provide a request for a specific file and provide a file accordingly. It is received (S60). In detail, the user selects any one of a list of search files output on the screen of the mobile communication terminal as a search result, and inputs a request for providing the corresponding file.

The agent transmits the input file providing request to the search engine, and the search engine receives the extracted file, converts the file according to the received file providing request into a form that can be implemented on the screen of the mobile communication terminal, and transmits it to the agent. The agent receiving the request file from the search engine outputs the file on the screen of the mobile communication terminal as shown in FIG.

Here, when the user requests for the provision of a specific file, if the file is a document file, the agent may provide the file to the user by dividing the file into summary keywords based on input keywords, document preview, document full view, and the like. Particularly, in case of the user's request to view the entire document, the user's scroll request is made by transmitting only the part centered on the search keyword and displaying it with a scroll when outputting on the screen of the mobile communication terminal without transmitting the entire document at once. Request additional parts so that they can be provided from search engines. This reduces the network burden associated with the entire file transfer.

In the above, a search system and method for a file stored in a computer device using a mobile communication terminal have been described. Although the present invention described above has been described with reference to preferred embodiments, various modifications and changes of the present invention are made without departing from the spirit and scope of the present invention as set forth in the appended claims by those skilled in the art. It will be appreciated that this can be changed.

As described above, according to the system and method for searching and providing files stored in a computer device using a mobile communication terminal according to the present invention, a user is provided with a search agent interworking with a search engine installed in a user computer device. By performing direct communication between the computer device and the mobile communication terminal, only one mobile communication terminal can search and receive files stored in the user computer device regardless of time and place.

In addition, wireless communication between the mobile communication terminal and the user computer device is enabled, so that the storage space of the user computer device can be utilized as a means of replacing the insufficient storage capacity of the mobile communication terminal.
