Description

Search service providing method by wireless Internet}

The present invention relates to a method for providing a wireless Internet search service, and more particularly, to a method for providing a wireless Internet search service for providing a search result page via an SMS linking a URL with a callback.

In recent years, with the rapid development of communication technology, mobile phones and personal digital assistants (PDAs) with mobile communication functions (hereinafter referred to as 'mobile communication terminals') are becoming indispensable personal necessities. Furthermore, the range of use of mobile communication terminals is expanding from simple voice calls to chats, text messages, video image storage and transmission using camera phones, real-time video viewing, and wireless Internet search.

Meanwhile, in providing a wireless Internet service using a mobile communication terminal, a method of using a wireless Internet portal site operated by a mobile communication service provider subscribed to by a user and a mobile origination provided by the present applicant (hereinafter referred to simply as 'MO') are provided. ) Through services. In the former method, i.e., a method using a wireless Internet portal operated by a mobile carrier, when the user presses a WAP browser execution button provided on the mobile terminal, the portal site is automatically connected. Sites organize their content by topic, and the topics covered are limited to news and entertainment. Therefore, if a user wants to search for a keyword according to this method, once he is connected to such a portal site, he must receive several swap pages sequentially to access the keyword input screen for keyword search. Since a key operation must be performed, there is a problem that the communication cost is high and the operation is cumbersome.

On the other hand, in the case of the MO service provided by the applicant, the excessive communication cost and inconvenience are alleviated somewhat. In brief, the user presses a specific button, for example, "**" in the standby state of the mobile terminal, and then enters an identification code (number) of an arbitrary swap server recognized by an advertisement, and then calls. When the button is pressed, the carrier checks the "**" mark and transmits the identification code following to the MO server operated by the applicant. After that, the MO server searches its own database to extract the URL of the homepage corresponding to the identification code of the swap server, and returns an SMS to the user, which links the URL with a callback. Press to access the swap page with the URL linked to the SMS.

However, in the case of such MO service, it alleviates the inconvenience of communication cost and key operation that is required to access the desired swap page, and it is inconvenient and difficult to receive the swap page according to the desired keyword search result. there was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and provides a swap search result page via SMS linked with a callback URL, thereby providing a quick and convenient wireless Internet search with a low communication cost and a small number of key operations for the user. The purpose is to provide a way to provide services.

Wireless Internet search service providing method of the present invention for achieving the above object comprises the steps of (a) receiving a keyword string and a terminal identification code to transmit a search result page; (b) performing a keyword search on its own by the keyword string received in step (a) or delivering the keyword string to an external swap search server and temporarily storing the returned search result page by requesting a keyword search; (c) transmitting a callback SMS linking the URL where the search result page is located to the mobile communication terminal designated by the terminal identification code; and (d) when the call is received from the mobile communication terminal, transmitting the search result page to the mobile communication. And transmitting to the terminal.

In the above configuration, in the step (a), the keyword string and the terminal identification code are received from a mobile communication company, and the mobile communication company is located behind the search request key code when a predetermined search request key code is received from the mobile communication terminal. The existing data may be regarded as the keyword string and the terminal identification code of the mobile communication terminal may be added to the keyword string and transmitted.

Furthermore, in the step (a), the keyword string and the terminal identification code are received from a keyword conversion server, and the keyword conversion server receives the keyword equivalent number string and the terminal identification code from the mobile communication company and then converts the keyword equivalent number string to the keyword. After converting the character string into a character string and transferring the terminal identification code together, the mobile communication company regards the data present after the search request key code as the numeric string corresponding to the keyword when a predetermined search request key code is received from the mobile communication terminal. The terminal identification code of the mobile communication terminal may be added to the keyword corresponding number string and transmitted.

Furthermore, in step (d), an advertisement message may be transmitted for a predetermined time before transmitting the search result page.

Hereinafter, a method of providing a wireless Internet search service according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The present invention can be achieved by applying and extending the above-described MO service to keyword search.

1 is a flowchart illustrating a method for providing a wireless Internet search service according to an embodiment of the present invention, in which a dotted line indicates a wireless communication flow and a solid line indicates a wired communication flow. As shown in FIG. 1, in the method of providing a wireless Internet search service according to the present invention, a keyword string is mainly associated with a mobile communication terminal 100, a mobile communication service provider 200 providing a mobile communication service, and a mobile communication service provider 200. The keyword conversion server 300 and the keyword conversion server 300 that provide a service for converting the character string into the search result page are generated by the keyword string received from the keyword conversion server 300, or an external WAP search server (not shown) is requested. After receiving the search result page it may be made including a swap search server 400 for delivering the callback SMS linked to the user's mobile communication terminal (100).

In the above-described configuration, the user's mobile communication terminal 100 is sufficient as long as the wireless Internet is possible, it is not necessary to install a separate hardware or software for the implementation of the present invention. The keyword conversion server 300 again includes various strings, that is, a dictionary DB 320 which stores vocabularies such as Korean, English, nouns, and surveys, and numeric strings corresponding thereto, information of numeric strings capable of input errors, and the corresponding vocabulary. Conversion engine that converts the numeric string information received from the mobile service provider 200 to the keyword string originally intended by the user by querying the error search DB 330 and dictionary DB 320 and the error search DB 330 that store the 310 may be included. In this case, considering that each manufacturer of the mobile communication terminal 100 adopts a different character input interface, the dictionary DB 320 or the error retrieval DB 330 should be provided with a conversion table according to these different character input interfaces. something to do.

The swap search server 400 reads the contents of various wired / wireless pages scattered on the Internet, and repeatedly visits a site linked to the page, and checks whether the corresponding page is updated. And an indexing engine 420 for classifying the contents of wired / wireless pages collected by the robot agent 430 based on the vocabulary stored in the dictionary DB 425 and the vocabulary stored in the dictionary DB 425. The search results of the search engine 415 and the search engine 415 that extract information matching the criteria of a given keyword from the indexing DB 435 and the indexing DB 435 that store the classified content by the indexing engine 420). Template Viewer (455), which displays pages as wired / wireless templates, and summarization tables (Summar) that manage the types of indexing summary information and accumulate data for these types of summary information. y Table) 445, an advertisement processing module 440 for processing and managing the transmission of advertisements to the mobile communication terminal 100, an SMS sending logic 450 for sending a callback SMS linked to a URL containing a search result page, and It may be made to include an integrated management module 410 to integrally manage the overall function of the swap search server 400.

In the present invention having the above-described functional configuration, in order for a user to search for a keyword through the mobile communication terminal 100, a predetermined search request key code, eg, in a standby screen state, that is, a folder of the mobile communication terminal 100 is opened, For example, press "**" and then input a string of strings (hereinafter referred to as 'keyword equivalent string') corresponding to the keyword string you want to search according to the character generation method unique to the mobile communication terminal 100, and then call. A button (or a swap browser execution button) is pressed (S100). The reason for doing this is that the current mobile communication terminal 100 does not support directly inputting a character in a standby screen state.

Table 1 below illustrates a structure of data generated when a keyword search request is made in the mobile communication terminal 100.

Search request key code Keyword equivalent number string Server-Specific Key Code Search server identification code Call button key code ** E.g. 81200821 * E.g. 2001 send

In Table 1 above, the total length of the entire data may be determined within 100 bytes, and the search request keycode and server-specific keycode may be changed to different keycodes, for example, "##" and "#". Could be The server-specific keycode can be omitted when the user directly specifies a swap server to request a keyword search. The server-specific keycode can be omitted, or the search server identification code is present after the server-specific keycode "*". If not, it determines that its own swap search server 400 is designated and performs the search in itself.

Next, the search request sent from the mobile communication terminal 100 is transmitted to the mobile communication company 200. In the mobile communication company 200, as shown in the beginning of the data transmitted from the mobile communication terminal 100, "**". If a predetermined search request keyword exists, it is determined as a keyword search request and the remaining data following the identification code of the mobile communication terminal (eg, MIN) requesting a keyword search according to a predetermined appointment is determined. It is passed to the keyword conversion server 300 (S110). Table 2 below is a table illustrating a structure of the data delivered by the mobile communication company 200 to the keyword conversion server 200.

Keyword equivalent number string Server-Specific Key Code Search server identification code Terminal Identification Code E.g. 81200821 * E.g. 2001 MIN

Next, the keyword conversion server 300 that receives the remaining data as shown in Table 2 from the mobile communication company 200 inquires the keyword equivalent numeric string included in the received data in the dictionary DB 320 and corresponds to the corresponding keyword. In the process (S120), since there may be an input error of the numeric string corresponding to the keyword in this process, the error search DB 330 is searched together and converted into the most similar keyword string. When the keyword string is generated in this way, the keyword conversion server 300 delivers the remaining data including the converted keyword string to the swap search server 400 (S130), after which the keyword in the swap search server 400 The keyword string received from the conversion server 300 is searched in the indexing DB 435 to generate a search result page and then temporarily stored (S140). Table 3 below is a table illustrating the structure of the data delivered by the keyword conversion server 300 to the swap search server (400).

Keyword string Server-Specific Key Code Search server identification code Terminal Identification Code Ex) Samsung * E.g. 2001 MIN

Next, the swap search server 400 delivers the callback SMS linked to the URL where the search result page is located by the SMS sending logic 450 to the user's mobile terminal 100 (S150). The communication terminal 100 can be confirmed by the terminal identification code received as illustrated in Table 3. In response to this, when the user presses a call button, for example, the reply is transmitted to the swap search server 400 (S160), and the swap search server 400 subsequently selects a predetermined time (1-10 seconds later). 3 seconds) to send the advertisement in a predetermined manner (S170). Such advertisement transmission may be a major revenue source of the keyword conversion server 300 or the WAP search server 400.

Next, as soon as the transmission of the advertisement is finished, the WAP search server 400 transmits the search result page requested by the user to the mobile communication terminal 100 of the user (S180). Accordingly, the user searches for the desired keyword. You can easily receive the page. As described above, according to the embodiment of FIG. 1, since a communication fee is charged only when a user receives a search result page, communication cost for a wireless Internet service can be greatly reduced, and keyword conversion is performed even if a search keyword is not entered as a string. Since the server 300 and the swap search server 400 process the necessary conversion and search, the search result page is transmitted and the cumbersome key manipulation process can be omitted.

On the other hand, when a user designates an external WAP search server that requires a keyword search directly, the WAP search server 400 checks this by the existence of the server-specific key code "*" and then assigns the WAP designated by the search server identification code following it. After passing the keyword string received in step S130 to the search server (not shown) and handing over the search result page, step S150 is performed. In this case, the swap search server 400 will only function as a swap gateway.

2 is a flowchart illustrating a method for providing a wireless Internet search service according to another embodiment of the present invention, wherein a dotted line represents a wireless communication flow and a solid line represents a wired communication flow. The embodiment of FIG. 2 assumes a case where the mobile communication terminal can directly input a keyword string in the idle screen state. In order to enable this embodiment, for example, when a pre-assigned key button is pressed in the idle screen state. The software of the mobile communication terminal should be changed so that text input is possible. In addition, in this embodiment, since the user directly inputs keyword characters while viewing the screen of the mobile communication terminal, the keyword conversion server 300 as in the embodiment of FIG. 1 is not required, and thus, the mobile communication company 100 directly searches for a swap. The user inputs the data to the server 400. Since the rest of the flow is the same as that of FIG. 1, detailed description thereof will be omitted. According to the embodiment of FIG. 2, since a user directly inputs a keyword while looking at the screen of the mobile communication terminal, a keyword input error may be reduced as compared to the embodiment of FIG. 1, thereby receiving a more accurate search result page.

According to the embodiment of FIG. 2, the structure of data transmitted from the mobile communication terminal 100 ′ to the mobile communication company 200 may be as illustrated in Table 4 below. The structure of the data passed to 400 may be as illustrated in Table 5 below.

The method for providing a wireless Internet search service of the present invention is not limited to the above-described embodiments and can be modified in various ways within the scope of the technical idea of the present invention. For example, although the embodiment of FIG. 1 and FIG. 2 independently illustrates the keyword conversion server 200 and the swap search server 400, the keyword conversion server 200 and the swap search server 400 may be operated together. In this case, a redundant configuration may be omitted. Further, both the keyword conversion server 200 and the swap search server 400 may be directly operated by the mobile communication company 200. In this case, the overlapping configuration may be omitted.

According to the method for providing a wireless Internet search service according to the present invention as described above, a key manipulation process is performed because a search result page can be received through a callback SMS simply by inputting a keyword and other necessary data in a standby screen state. Since the communication cost is charged from the point of receiving the search result page, the communication cost can be greatly reduced. In addition, since the keyword conversion server or the WAP search server can generate revenue by attracting advertisements sent to users immediately before sending a search result page, the wireless internet search service can be activated.
