Description

Wired Content Retrieval System and Method over Wireless System Using Content Reformatter {SYSTEM AND METHOD FOR SEARCHING CABLE CONTENTS ON WIRELESS USING CONTENTS REFORMATTER}

The present invention relates to a wireless retrieval system, and more particularly, to a wired content retrieval system and method over the air using a content reformer capable of providing a high quality wireless retrieval service by retrieving and converting wired content to wireless.

Recently, a mobile communication system such as a code division multiple access (CDMA) system has been in the spotlight as a next generation mobile communication system capable of not only voice service but also data and video services. Accordingly, mobile communication systems are being developed to enable high-speed data services for services such as data and images. For example, as the wireless web service to the mobile communication terminal progresses, its functions such as games, internet search, and wireless broadcasting service using the mobile communication terminal are diversified.

However, the wireless Internet data service using the mobile communication terminal has all the components required to deliver data due to various constraints such as inconvenience of data input, limitation of display screen size, etc. in a presentation type through a menu. Accordingly, in order to view the content that does not exist on the menu, the user must memorize a Uniform Resource Locator (URL) of the desired content, and even if the user memorizes, it is inconvenient to input the URL on the mobile terminal. have. Therefore, wireless content provided by a wireless Internet service using a mobile communication terminal has a disadvantage in that the information transmission power is significantly reduced in terms of quantity and quality, unlike wired content provided by wired Internet due to the characteristics of a network environment and hardware.

Accordingly, an object of the present invention is to provide a wired content retrieval system and method over a wireless network using a content reformer that can provide wired content by providing a high-quality wireless Internet service by retrieving wired content and converting the result into a wireless format through a content reformer. To provide.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2.

1 is a diagram illustrating a wired content retrieval system wirelessly using a content reformer according to an exemplary embodiment of the present invention.

The wired content retrieval system on the wireless network shown in FIG. 1 is connected to a web server 40 that provides wired content via the Internet 30, and wired content according to a search request from the mobile communication terminal 10 through a wireless network. And a mobile communication service system 20 for converting the search result into a wireless format and providing the search result.

The mobile communication terminal 10 includes a wireless Internet browser and provides a wireless communication service system 20 through a wireless network based on a wireless internet protocol such as a wireless application protocol (hereinafter, referred to as WAP). Internet service will be performed. The mobile communication terminal 10 drives the wireless Internet according to a user's instruction to request the mobile communication service system 20 to search for content input by the user, and to display a content search result page provided from the mobile communication service system 20. Done.

The mobile communication service system 20 performs a wireless Internet service requested by the mobile communication terminal 10. In particular, the mobile communication service system 20 provides wireless content on request in the mobile communication terminal 10. In addition, the mobile communication service system 20 searches for wired content by accessing the web server 30 through an internet network at the request of the mobile communication terminal 10, and retrieves the wired content search result from the mobile communication terminal 10. Provides conversion to wireless format suitable for wireless internet browser.

To this end, the mobile communication service system 20 includes a WAP gateway 21 for a wireless interface with the mobile communication terminal 10, a search service server 22 connected to the WAP gateway 21, and a search service server 22. A content reformatter 25 connected between the connected search engine 23, the search service server 22 and the wired Internet network 30, and a search index database connected to the search engine 23 (hereinafter referred to as DB). (24).

The WAP gateway 21 serves as a wireless interface to enable wireless internet between the mobile communication terminal 10 and the search service server 20.

The search service server 22 provides a wireless Internet service according to a request of the mobile communication terminal 10 through the wireless network and the WAP gateway 21.
