The connection method of the wireless Internet according to the prior art not only acts as an obstacle to preventing the activation of the independent portal, but also causes a lot of inconvenience for the user.

Various methods have been devised to remove such inconvenience and improve accessibility of wireless Internet users. Among the conventional technologies, a number domain or callback URL, SMS, barcode, and icon recognition method for accessing the Internet by number is known. It is emerging as a new method of initial wireless Internet access. Here, the callback URL is a callback URL that transmits a URL of a wireless portal to a short message service (SMS) and automatically connects to a corresponding site when a call button is pressed. When the site transmits the callback URL text message to the user's mobile phone, the users can register the received URL in the favorite menu and access the desired site by using the menu.

The URL information extracting unit 413 may determine whether it is a signal for accessing a specific site or a signal for requesting a search list by using the string information, and provide an Internet access service corresponding to the determination result. Table 1 below summarizes an embodiment of a method of extracting detailed URL information by analyzing a code according to the present invention.

division action Remarks Request connection Request a string DNS server to extract the URL information of the site corresponding to the string http: //, *, http: // * Search request Request to search server to extract search list using string as search keyword Logical Operators Available

The URL information extracting unit 413 determines whether the internet access request signal is an access request signal or a search request signal by using a preset identifier. Here, separate identifiers (eg, connection identifiers and search identifiers) may be used to distinguish the signals, or may be configured to distinguish the two signals using only one request signal. Hereinafter, a description will be given based on the case where the connection identifier is used only for the connection request signal.

For example, if you want to access Katie F. Freetel, the string included in the internet connection request signal may be a string including a site name to be connected to a predetermined identifier (for example, http: // katie, * katie, http: / / * Katy), and recognizes this as a connection request signal, and transmits the string information to the string DNS server 420 according to the present invention. The string DNS server 320 outputs a domain address corresponding to the string. For example, if "KT" is input to the Korean DNS server 320 as a string, the domain address "http://www.ktf.com" of the web server is output.

When the preset access identifier is not included in the character string, the terminal recognizes this as a search request signal and transmits the character string information to a preset search server. The search server is configured to extract a search result corresponding to the character string information.

Here, the character string for the search may also be configured to include a predetermined format. For example, the search field may be configured in the order of a search field, an operator, and a search word to limit the search field by referring to the search field, and the search efficiency may be improved by searching only a region corresponding to the search field with the search word. In this case, the search field may be set according to a preset category such as stock, search, and location information. For example, when a certain movie is to be reserved, the efficiency of the search service can be improved by inputting in the format of a reservation matrix to search only a predetermined search field. In addition, by providing detailed URL information that can be reserved for the matrix, it can be configured to make the reservation easily. If Search * Jamaica, Jamaica can search for the term and provide the user with detailed information about Jamaica.

When the search field is limited by inputting location information, the search result may be configured to extract and provide only a search result corresponding to the location of the terminal. For example, when only a string such as 'flower delivery' is included, a search list corresponding to the flower delivery may be extracted and provided, and URL information corresponding to the search result may be provided. And even if no location information is input, the location of the terminal can be tracked and only a search list corresponding to the location of the terminal can be extracted and provided.

When the string DNS server 420 is a connection request signal, the string DNS server 420 is configured to provide detailed URL information corresponding to the string. The string DNS server 420 includes a code analyzer 423 and an address register 427. It may further include. The code analyzing unit 413 is configured to extract the detailed URL information with reference to the address registration unit 427 from the received string information. The address register 427 configures, stores, and manages a mapping table of string information and detailed URL information.
