Thereafter, the search engine server 50 generates a search result and provides the same through the short message service.

According to the present embodiment, the search engine server 50 is provided with means for transmitting the search results in a short message.

Those skilled in the art will readily recognize that the above-described information retrieval method is technically sufficient to implement.

7 is a diagram for explaining a wireless Internet information retrieval method according to a second embodiment of the present invention.

Unlike the above-described embodiment, the present embodiment relates to a case in which a search request including a search query word is transmitted through a short message service, not through a wireless Internet connection of the mobile communication terminal 10.

When the user wants to search for information, the user transmits a search query to a specific search engine server 50 through the short message service of the conventional mobile communication terminal 10 to request a search.

In this case, the search engine server 50 that is the destination of the short message is represented by a specific number such as a mobile communication number, and the user transmits a short message including a search query to the specified corresponding number.

In the well-known fact or short message transmission, the sender also registers his receiving mobile communication number.

When a user inputs a search query as the content of a short message, the user may input a plurality of search queries. In this case, each search query is distinguished by a letter spacing. In addition, the user may transmit a short message in which the search query is made into a descriptive sentence.

On the other hand, the short message registered from the user is transmitted by the mobile communication terminal 10 to the search engine server 50, which is the receiver, via the online SMS server 40, the search engine server 50 of the transmitted short message Get a search query from the content.

The search engine server 50 obtains website (also, web document) information on the obtained search query using a search engine, and transmits the search result to the sender's mobile communication number through a short message service. The short message transmitted to the mobile communication terminal 10 is confirmed as in the conventional short message confirmation.

As described above, a user may request a search for a plurality of search queries, and the search engine server 50 may provide search results for the plurality of search queries. In this case, when it is impossible to transmit the search result in one short message, the search result may be divided into a plurality of short messages and transmitted.

According to the present embodiment, the search engine server 50 receives a short message of a user, obtains a search query from the content of the short message, constructs a search result of the obtained search query as a short message, and transmits the result to the user. Means are provided.

In the above two embodiments, the search results transmitted by the search engine server 50 include a name, a brief description, and a URL of a corresponding website (or web document).

Preferably, the search engine server 50 may provide only a limited number of higher ranking lists among a plurality of website lists that are search results for one search query. That is, within the amount of information that can be transmitted through the short message service, it is possible to provide only the search result that is the minimum personalized information considering the small screen size of the mobile communication terminal which is the user interface and the inconvenience of operation.

The website information, which is a search result provided to the user, is provided with a hyperlink for accessing the website, which is automatically generated when the user selects the website by operating a key panel of the mobile communication terminal 10. The browser is operated to provide the function to access the web page.

Of course, the advertisement content may be to advertise a specific website online, in this case, it is preferable that the advertisement content is provided with a hyperlink for linking to the website.

In addition, the user's search query may be a keyword or a sentence (question form). In the second embodiment in which the search query is transmitted in a short message, a descriptive sentence described in more detail than a sentence can be used. In other words, a user may write a search query in a descriptive manner so that the user can be provided with the best information that he / she wants. If the search query is a descriptive sentence, the search engine server 50 analyzes the descriptive search query to derive an optimal search result and provide it to the user.

According to the present invention, the search engine server 50 may perform a search with a margin in time and transmit the result in a short message later. That is, in the search through the conventional wireless Internet access, the search result has to be provided as soon as possible, and thus, there is a limitation in that an optimal search cannot be performed. However, according to the present invention, the search result can be provided later through a short message service. The search engine server 50 may provide an optimal search result by performing a search with some time margin. In other words, even if the user does not need to get a search result immediately and takes some time, this method can be effectively used. In fact, the above-described method may be more efficient than accessing and verifying a number of indiscriminate website information provided by a search engine server as in the related art.

From the above advantages, the present invention can be further extended, and search all the information serviced by the conventional wired internet information search as well as the website information search described above, as well as phone number search, dictionary search, news search, address book search, map search, etc. It can be used to.

For example, in the case of telephone number search, if the above-described search engine server 50 is replaced with a service server that provides telephone number information for a plurality of users who are only connected online, the same as the above-described main technical gist of the present invention. It can be properly implemented by application.

That is, the user releases the wireless Internet access link after transmitting a search query (eg, "Patent Office") to the phone number service server using the mobile communication terminal, and the phone number service server searches for the search query. Generates a result (for example, "Complaint Office and telephone number: 02-588-5757") and transmits it to the user's mobile communication terminal through a short message service.

In another aspect, a user transmits a search query word (eg, "Patent Office") to a telephone number service server online through a text message service, wherein the telephone number service server sends the transmitted text. Obtain a search query from the message and generate a search result (for example, "KIPO complaint and phone number: 02-588-5757") and transmits it to the user's mobile communication terminal through a text message service.

In this case, it would be desirable for the transmitted phone number (search result) to immediately attempt a call when the user presses the call button.

Those skilled in the art will readily recognize that other dictionary searches, news searches, address book searches, map searches, and the like may also be implemented by the present invention.

Furthermore, it should be recognized that the above descriptions about the website search can be equally applied to the telephone number search, dictionary search, news search, address book search, and map search.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of equivalent claims.

According to the wireless Internet information retrieval method of the present invention, it is possible to obtain the best search results without accessing the old wireless Internet for information retrieval, saving the cost of information retrieval, considering the user's inconvenient interface A new type of wireless Internet information retrieval method is provided that provides results.
