Method for Providing Information Service to Wireless Terminals, and Information Service System and Messaging Agent System Suitable for the Same}

The present invention relates to an information service providing method for a data terminal, and more particularly, to an information service providing method for a wireless terminal. In addition, the present invention relates to an information service system for directly implementing the information service providing method, and a gateway system for implementing the information service providing method through a content provider and a wireless terminal user.

Short message service (hereinafter, abbreviated as "SMS") provided by mobile phone providers is commonly used to exchange short messages between wireless terminals. The transmitting client that transmits the short message may be a PC communication server or an Internet server in addition to the wireless terminal. However, SMS is difficult to transmit useful information other than the returning phone number because the length of the message that can be transmitted is extremely short, and is used to send or receive greetings or other greetings between acquaintances or the mobile phone provider to provide guidance messages to subscribers. There is only.

In order to provide more useful and systematic information to mobile subscribers, various services have been proposed and many of them are actually implemented, for example, provided by mobile operators or information providers (CPs) affiliated with them. Various supplementary services, and wireless internet that allows mobile subscribers to access the Internet through their telephones. In particular, the Wireless Application Protocol (WAP), which was established by the WAP Forum in 1997 and has been upgraded several times, is becoming the core of the wireless Internet-based technology that enables various Internet applications and contents to be accessed through wireless terminals.

However, since most of the commercially available wireless terminals have a small display size, additional services or wireless Internet provided by existing mobile phone providers are inconvenient and limited in surfing information, and therefore, the amount of information that can be obtained must be concise. The disadvantage is that. In addition, in a state where the data transmission speed of the mobile telephone network is low, there is a high possibility that the fee paid by the information service user is excessive compared to the time of receiving or surfing data. The excessive information acquisition time and the burden of charges can be an obstacle in suppressing an increase in demand for wireless data services and maximizing the utility of the wireless terminal. Therefore, there is a strong demand for a method that enables each wireless terminal user to quickly access the information he needs or is interested in.

The category selection may be made through a wireless terminal or a wired internet, and may be made through field selection or keyword designation by a menu method. When a new content belonging to a category set by the user is newly generated, the system notifies the user that the content has occurred. In this case, the notification message includes content identification information as well as information on occurrence of content and / or content type. The user can request the actual content by transmitting the content identification information to the system by selecting the content information displayed on the display of the terminal. In response to the content request of the user terminal, the actual content is provided to the user terminal.

In a preferred embodiment, the notification message is pushed to the user terminal via SMS and the actual content is provided according to the WAP. In order to shorten the length of the notification message transmitted via SMS, the system compresses an extension except for the domain name in the URL string of the content into a code according to a predetermined rule in generating the notification message, the domain name and the user terminal number, and A compressed URL including code is generated, and the compressed URL is used as the content identification information. When a content request is received from the user terminal, the system restores the original URL from the content identification information, that is, the compressed URL, so that the content of the URL can be provided to the user terminal.

On the other hand, according to the information service system of the present invention for achieving the above another technical problem, the information service provider has to directly hold the contents, accept the registration request for category setting from the user, and provide the information service based on the content database and the user database do. In this case, the information service provider may be a wireless communication provider.

In the information providing system, the first storage means stores user information including information on a selected category for which each user wants to receive an information service, and the second storage means stores a plurality of contents. The judging means judges whether new contents belonging to the category stored in the first storage means among the contents stored in the second storage means. When new content is generated, the URL link generating means replaces an extension except for a domain name in the URL string of the content with a predetermined code, generates location information by including a domain name and the code, and converts the location information into the first code. Stored in storage means and provided to message generation and transmission means. The message generating and transmitting means generates and provides a notification message including the content occurrence information for notifying the occurrence of the content and the location information to the user's wireless terminal. The content providing means provides the content to the user's wireless terminal in response to the content request from the user terminal.

On the other hand, according to the messaging gateway system of the present invention for achieving the above another technical problem, the information service provider is requested to notify the user of the content occurrence from another information provider (CP), in response to the user The notification message is transmitted, and when a content request from the user is received, the content request is transmitted to the information provider CP so that the content can be provided to the user terminal.

In the messaging agent system, in response to the notification request, the URL link generating means maps the content location information included in the content information in the notification request according to a predetermined rule to generate mapped location information, and the storage means generates the mapped location information. Saved location information. The message generating and transmitting means generates and provides a notification message including the location information mapped with the content occurrence information for informing the occurrence of the content to the user's wireless terminal. And, in response to the content request of the user terminal, the content providing means allows the content to be provided to the user's wireless terminal with reference to the mapped location information stored in the storage means.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 schematically shows an example of an information service providing method according to the present invention. According to the scheme of FIG. 1, an information service provider directly retains contents, receives a category setting registration request from a user, and provides an information service based on a content database and a user database. In this case, the information service provider may be a wireless communication provider.

The information service system 30 may be connected to the user terminal 10 through a wireless communication network. The system 30 receives a user registration request for the user of the wireless terminal 10 and holds personal information including the terminal number of each user. User registration may be performed through the wireless terminal 10, but may be performed through a wired internet by a separate data terminal. When registering a user, the information service system 30 allows each user to select a category of content of interest. The category selection is made through field selection or keyword designation by menu method. The category selected and set by each user and the corresponding information are stored and maintained in the database of the information service system 30.

The information service system 30 continuously determines the content, while determining whether the content belongs to the category selected by the user. If the content belonging to the category selected by the user is generated or secured, the information service system 30 notifies the user of the occurrence of the content via SMS. Upon receiving the notification message, the user may access the information service system 30 to acquire the actual content. In this process, data communication according to WAP is used in the process of acquiring the actual content. As such, when the information service system 30 pushes the content information to the user via SMS, in response, the user acquires the corresponding content by the WAP according to his or her intention.

If the user wants to obtain the actual content by the WAP, the user may directly input the URL of the information service system 30 or use the bookmarked URL. However, in the preferred embodiment, the information on the URL of the content is included in the notification message provided through the SMS, so that the user can easily access the content. On the other hand, in order to enable data communication by WAP, the user terminal 10 is preferably equipped with a WAP browser.

2 shows an embodiment of an information service system according to the present invention in more detail. As shown, the information service system 30 includes a web server 32, a database 34, an SMS subsystem (SMSS, 36), a WAP proxy server 38, a filter 40 and an informational main server 42. ).

The web server 32 may be connected to external information provider (CP) servers 90a through 90n through the Internet, and thereby continuously accumulate content and accumulate the secured content in the database 34. In addition, the web server 32 may access the Internet client terminal 92 through the wired Internet, and in response to a request of the Internet client terminal 92, at least one of contents owned or stored in the database 34 may be used. Some can be provided.

The SMS subsystem 36 may be connected to a Short Message Service Center (SMSC) 26 of a wireless carrier, and the user terminal 10 may be connected via the SMSS 26 at the request of the web server 32. Send a short message to).

In the information service system 30, the WAP proxy server 38 is connected to a web server 32, and is connected to an exchange 22 of a wireless communication network via an interworking function 24 (IWF). The IWF 24 is a gateway that allows a wireless communication network and a wired network to be connected. Since the device is well known to those skilled in the wireless communication field, detailed description thereof will be omitted. Meanwhile, the WAP proxy server 38 may be directly connected to the base station 20 of the wireless communication network through the data network PSDN.

The WAP proxy server 38 allows the user terminal 10 to connect to the web server 32 by converting the WAP protocol stack to the WWW protocol stack and conversely converting the WWW protocol stack to the WAP protocol stack. That is, the WAP proxy server 38 converts the WAP request from the user terminal 10 into a WWW request so that the terminal 10 can send its request to the web server 32, and the web server 32 By converting the response of the response to the WAP protocol and transmits it enables to understand the response content mounted on the terminal 10. Meanwhile, some of the contents provided by the information providing system 30 may be directly written in WML (Wireless Markup Language) and provided by the WTA (Wireless Telephony Application) server 42.

3 illustrates in detail the program modules mounted on the information providing main server 40. In a preferred embodiment, the informational main server 40 includes a WAP menu management procedure 50, a short push procedure 52, a URL link procedure 54, a content DB management procedure 56, and a subscriber management procedure 58. Programs are mounted. 3 also shows a database 34. The database 34 includes a content DB 60 and a user DB 62, which may each be one table or multiple tables.

The WAP menu management procedure 50 is provided to the user terminal 10 to efficiently provide the WAP content provided in a general manner to the user terminal 10, rather than the case of requesting the content by specifying a URL after being pushed to the short message by the present invention. Allows you to create and manage WAP menus.

The SMS push procedure 52 continuously refers to the content DB 60 and the user DB 62 of the database 34 to newly obtain or generate the content of the category set by each user (in the following description and claims). (Abbreviated as "produce" or "produce"). When the contents of the category set by the user are newly generated, the SMS push procedure 52 causes the URL link procedure 54 to generate new URL link information, and the corresponding information is transmitted through the web server 32 and the SMSS 36. The user is notified that new content exists.

The URL link procedure 54 compresses the URL included in the notification message in order to shorten the length of the notification message sent via SMS. Specifically, the URL link procedure 54 compresses an extension except for the domain name among the URL strings of the content into codes according to a predetermined rule, generates a compressed URL including the domain name and the user terminal number and the code, and compresses the compressed URL. The provided URL to the SMS push procedure 52. In addition, the URL link procedure 54 stores link information between the original URL and the compressed URL in the database 34. When a content request is received from the user terminal, the URL link procedure 54 reads from the database 34 the original URL corresponding to the compressed URL in response to the request of the web server 32 and sends it to the web server 32. to provide. On the other hand, in another embodiment of the present invention, such original URL verification may be performed directly by the web server 32.

The content DB management procedure 56 classifies the newly generated content into each category and assigns an index word when there is new content. The subscriber management procedure 58 manages information about each user subscribed as a member.

In an embodiment in which the preferred embodiment is modified, some or all of the program modules mounted on the informational main server 40 described above may be included in the web server 32, and in this case, in the form of a client script or a server script. It may be On the other hand, each server in the system may be installed in a physically separate device, but may be implemented in one physical server.

4 illustrates an example of a notification message format provided as an SMS to a user terminal in the information service system of FIG. 2. The notification message includes a teleservice ID (TID) 70, a content information 72, a delimiter 74, a compressed URL 76 and a callback (CB) telephone number 78. The TID 70 is a unique number assigned to each wireless communication provider. When the information service is performed through a plurality of wireless communication providers, the number of the service provider to which each user is subscribed is inserted. The content information 72 is a message displayed on the user terminal 10 as information on occurrence of content and / or content type. The separator 74 is used to distinguish the content information 72 from the compressed URL 76 and may be omitted.

In a preferred embodiment, the compressed URL 76 is in the form of a concatenation of the domain name 80, the user telephone number 82, and the serial number 84 of the information service system. If the domain name 80, the domain name portion of the original URL string is used as it is. On the other hand, the extension except for the domain name in the original URL string is replaced by the user telephone number 82 and the serial number 84. The serial number 84 is assigned by the URL link procedure 54 of the information providing main server 40 in accordance with the order in which the SMS message is transmitted for each user for a predetermined period of time. The mapping information between the original URL string and the compressed URL, or the code in the extension and the compressed URL in the original URL string, that is, the mapping information between the user telephone number 82 and the serial number 84, is stored in the database. When a content request is received from the domain name and the user terminal 10, the URL link procedure 54 or the web server 32 of the information providing main server 40 restores the original URL from the compressed URL 76. The content of the URL can be provided to the user terminal 10.

5A and 5B are diagrams for describing a method of generating a compressed URL used as content identification information in the notification message of FIG. 4. As shown, the first serial number 84 has a value of "00" and each time the next short sentence is provided, the serial number is incremented.

6 illustrates in detail the process of providing information in the system of FIG. The information service provider continuously accumulates and updates the content (step 100). Each time new content is generated or at regular time intervals, the SMS push procedure 52 of the main server 40 determines whether new content of a category set by each user is newly generated (step 102). When the contents of the category set by the user are newly generated, the URL link procedure 54 generates the compressed URL and stores the URL link information in the database 34 (step 104). The compressed URL and the member information are provided to the WTA server 42 (step 106). The web server 32 or the WTA server 42 generates a short message based on the compressed URL and the member information and transmits the short message to the corresponding user (step 108).

When a content request is received from the user terminal (step 110), the web server 32 or the WTA server 42 first checks the original URL from the database 34 (step 112). When the original URL is confirmed, the web server 32 or the WTA server 42 reads out the content and transmits the content to the subscriber station according to the WAP (steps 114 and 116). On the other hand, when the user who has received the short message wants to check the specific content, he or she may connect to the web server 32 via the wired Internet using a PC or the like instead of the wireless terminal 10 of the user.

7 schematically shows another example of the information service providing method according to the present invention. According to the scheme of Fig. 7, user registration and category setting are made to the external information provider CP, and content provision is also made by the external information provider CP. The information service provider will function as a messaging agent that mediates the transfer of information between the information provider (CP) and the user. Here, the external information provider (CP) may be, for example, financial companies, securities companies, media companies, shopping malls and the like.

Each CP server 290a-290n continuously secures the content, and determines whether the content belongs to the category selected by the member. If the content belonging to the category selected by the user is generated or secured, the CP servers 290a to 290n request the messaging agent system 30 to notify the user of the occurrence of the content. In this case, the notification message includes a URL regarding content to be provided by the CP servers 290a to 290n. The messaging agent system 30 sends a notification message to the user in response to the notification request. In addition, the messaging agent system 30 transmits a content request corresponding to the content request from the user to the information provider CP so that the content can be provided to the user terminal.

Figure 8 shows in more detail an embodiment of a messaging agent system according to the present invention. The messaging agent system 230 of FIG. 8 may be configured similarly to the information service system 30 of FIG. 2 in terms of hardware, but only in software in view of its functional differences. Hereinafter, the configuration and operation of the messaging agent system 230 will be described based on differences from the information service system 30 of FIG. 2.

When the web server 232 is requested to send a notification message from the CP servers 290a to 290n, the main server 240 generates a compressed URL and then sends a short message including the compressed URL to the SMSS 236. Through the transmission to the user terminal 10. When a content request is received from the user terminal 10, the web server 232 determines the format of the corresponding content based on the original URL. If the content is in the form of a WAP, the web server 232 forwards the content request from the user terminal 10 to the corresponding CP servers 290a-290n, whereby the CP servers 290a-290n receive the content. The content is directly provided to the user terminal 10. However, if the content is in a format suitable for the wired Internet such as WWW or FTP, the web server 232 takes the content from the CP servers 290a-290n, converts the content to WAP, and provides it to the user terminal 10. do. The determination of the format of the content may be made by the main server 240 instead of the web server 232.

9 illustrates in detail the program modules mounted on the messaging agent main server 240. In a preferred embodiment, messaging agent main server 240 is loaded with programs such as WAP menu management procedure 250, URL link procedure 252, and content DB management procedure 254. 3 also shows a database 234. The database 234 includes a content DB 260 and a URL link information DB 262, which may each be one table or multiple tables.

10A to 10C are diagrams for describing a method of generating a compressed URL used as content identification information in a notification message provided to the user terminal 10 by the messaging agent system 230 of FIG. 8. As shown, the first serial number has a value of "00" and the serial number is incremented each time the next short sentence is provided. In a preferred embodiment, content to be provided by the CP servers 290a-290n may have a format according to WAP as described above, or may be in a format suitable for wired Internet. The URL link procedure 254 of the main server 232 generates a compressed URL in the same form regardless of the format of this content.

In a preferred embodiment, the compressed URL is in the form of a concatenation of the domain name of the messaging agent system, the user's telephone number, and the serial number. That is, the domain name of the corresponding CP among the original URL strings assigned to the content before the domain name compression is replaced with the domain name of the messaging agent system, and the extension except the domain name among the original URL strings is replaced by the user's telephone number and serial number. Replaced. The serial number is assigned according to the order in which SMS messages are sent for a certain period of time, for example, for each user, regardless of the domain name of each content. The URL link procedure 254 stores in the URL link information DB 262 the mapping information between the original URL string and the entire compressed URL, the code in the original URL string and the compressed URL, that is, the user telephone number and the serial number. When the content request is received from the user terminal 10, the URL link procedure 254 or the web server 32 of the main server 240 of the messaging agent system restores the original URL from the compressed URL, Allows content to be provided to user terminal 10.

11A and 11B illustrate a process of mediating content delivery in the system of FIG. 8 in detail. Each CP server 290a-290n continuously accumulates and updates content (step 300). Each time a new content is generated or a predetermined time interval, it is determined whether the content of a category set by each user is newly generated. When the contents of the category set by the user are newly generated, the CP servers 290a to 290n include the user's telephone number and the content URL to request the notification message transmission to the messaging agent system 230 (step 304). ). After the URL link procedure 252 of the messaging agent system 230 generates the compressed URL and stores the URL link information in the DB 262 (step 304), the web server 232 generates a notification message based on this. In step 306 and 308, the user is transmitted to the corresponding user by SMS.

When the content request is received from the user terminal 10 (step 310), the web server 232 first checks the original URL from the URL link information DB 34 (step 312). Next, the web server 232 enables the corresponding content to be provided to the user terminal 10 according to steps 312 to 316 of FIG. 11A or steps 318 to 322 of FIG. 11B.

If the content is in the form of WAP, the web server 232 forwards the content request from the user terminal 10 to the corresponding CP servers 290a-290n (step 314). That is, when the web server 232 receives the content request from the user terminal 10, the web server 232 refers to the terminal number and the serial number included in the content request, and restores the original URL string for the corresponding content. Web server 232 then forwards the content request to CP servers 290a-290n associated with the original URL string, including the terminal number for the wireless terminal. Accordingly, the CP servers 290a-290n can directly provide the WAP content to the user terminal 10. The web server 232 may load and execute a program for URL restoration and domain forwarding, which may be a single module or may be a separate module for URL restoration and domain forwarding. Since such a program can be easily implemented by those skilled in the art to which the present invention pertains, a detailed description thereof will be omitted.

On the other hand, when the content is in a format suitable for the wired Internet, as shown in Fig. 11B, the web server 232 receives the content from the CP servers 290a to 290n, and the web server 232 again receives the content from the user terminal. You may provide to (10). That is, when the web server 232 receives the content request from the user terminal 10, the web server 232 refers to the terminal number and the serial number included in the content request, and restores the original URL string for the corresponding content. The web server 232 requests content from the CP servers 290a to 290n (step 318). When the content is received from the CP servers 290a to 290n (step 318), the web server 232 converts the content into the WAP protocol and provides the content to the user terminal 10 (step 320). In protocol conversion, the web server 232 may use any one or a combination of techniques known or present in the future as of the filing date of the present application, such as HTML reformatting, tad converting, web clipping, and the like. ) May include a separate protocol conversion program module.

The web server 232 forwards the content request from the user terminal 10 to the CP servers 290a-290n as shown in steps 312 to 316 of FIG. 11A so that the CP servers 290a-290n directly use the user. Whether to provide the content to the terminal 10, or to secure the content from the CP server (290a-290n) and provide it to the user terminal 10 as shown in step 318 to 322 of Figure 11b It may be irrelevant to the format of the content. Which of the two provisioning methods may be used may be determined according to the degree of security requirement of the content or the contract between the messaging agent system operator and the CP server 290a-290n operator, or the like.

12 shows examples of content suitable for the system of FIG. 9 to mediate transmission. First, news breaking news within a category set by a user may be provided for each sector such as politics, economy, and society, or for more specific fields or specific keywords. In addition, it may provide game results or breaking news for each sport that the user likes. It can provide general weather, living weather or weather information of a specific region, and entertainers can provide various information or emergency announcements or messages in providing information and operating a star fan club. The job / job site may cross-check job seekers and job seekers, notify SMS when new information is registered in a desired job, and then provide detailed information to the WAP. In addition, the user may be able to enter a condition regarding his or her ideal spouse award, and then notify all existing members of the opposite sex, or notify the person who is determined to be an ideal couple information about the user. In addition, such information may be provided to a person who wants life information regarding a prize or a coupon.

After receiving a messaging member registration for the customer, the bank may notify the account change history or the credit situation change history from time to time through the messaging agent system of the present invention. In addition, a credit card company can notify the user of each member's use of the credit card each time, thereby preventing the credit card from being used illegally without the card owner's knowledge. In the case of securities firms, it can also be used to guide the results of closing the quotes or orders for each stock. A member who wants to receive the shopping mall related information service may browse the information about the price of the product he / she needs or wants to purchase and purchase the product if he / she wants. In addition, instant messaging can be exchanged between users, and in this case, the message sender's personal homepage address is included in the message so that the message receiver can directly access the homepage.

It can also be used to report driver license penalties or penalties. In addition, it may be used to notify a personalized friend, or may be used to provide a promotional material (DM) in the field desired by the user. Furthermore, the information providing system or the messaging agent system of the present invention can be utilized in the form of a mobile Zine from the viewpoint of a system operator, CP, or user.
