Description

Wireless Internet Service System and Method

The present invention relates to a wireless Internet service system and method, and more particularly, to a short message broadcast service (CBS) using a wireless Internet service using WAP (Wireless Application Protocol) or a wireless Internet service using WAP and ARS (Audio Response System). The present invention relates to a wireless Internet service system and a method for providing all terminals in a desired area in association with a Cell Broadcasting Service.

In general, there are already hundreds of millions of wireless communication service subscribers all over the world. With the rapid increase in wireless communication, various services using wireless communication have been developed and spread. Commonly used wireless communication devices may include personal digital assistants (PDAs), two-way pagers, mobile telephones (including cellular telephones), gripped computing devices, and the like. The wireless communication system has been continuously developed from the ground transmission tower system in the 1890s to the geostationary satellite communication in the 1960s and the introduction of low-orbit mobile satellite communications in the 1980s. As the wireless communication system develops, the wireless internet service has also developed. The wireless Internet service refers to a service that allows users to access the Internet anytime, anywhere, as well as search for various information. When mobile phones were first introduced, mobile phones and PCs were completely separate devices, but with the emergence of wireless data, they have gradually converged and are now evolving into wireless Internet. Wireless internet using such mobile phones is classified into built-in and non-built-in type depending on the presence or absence of a browser, and the built-in type that allows users to enjoy all Internet services using only mobile phones is the mainstream. Early wireless Internet service is SMS (Short Message), a short message service that allows a digital mobile subscriber to send and receive short messages over public telephone networks, data communications networks, or the Internet when short sentences are sent to other mobile subscribers in Korean or English. Service, but now, you can use a variety of applications such as cyber shopping, stock trading, banking, life information.

In order to provide wireless Internet service in current mobile communication network, phone.com develops Handheld Device Transport Protocol (HDTP) and Handheld Device Markup Language (HDML), and TTML in Nokia (Tagged Text Markup Language) was developed, and Ericsson developed Intelligent Transfer Protocol (ITTP). Amid the enthusiasm for wireless internet in Korea, the area of wireless internet service is expanding as domestic portal service companies launch wireless internet service. For example, Yahoo Korea (http://www.yahoo.co.kr) launched wired / wireless portal service centered on search and mail through partnership with 011, 017, 019 operators, and 011, 017, 019 When subscribers access the Yahoo! Korea site through a terminal equipped with a WAP browser, they can check the mail service such as checking new mail, checking old mail, sending mail, checking external mail, directory search, English dictionary, stock price search, exchange rate information, weather information, etc. Related services are available. Navercom (http://www.naver.com) has partnered with SK Telecom to provide content search services and search services for WAP-based sites, and has been deployed in over 100 domestically using WML (Wireless Markup Language) and HDML. Site and overseas wireless site search service will be provided. Daum Communications (http://www.daum.net) provides Daum mobile services that can use the Internet service wirelessly, and Lycos Korea (http://www.lycos.co.kr) is also the satellite of the future online. The company plans to provide a wireless Internet service that combines broadcasting and its contents.

However, such a conventional wireless Internet service has various problems. First, in order to use a wireless Internet service provided by a wireless Internet service company, a subscriber needs to directly search for and use a desired content. As a solution, some wireless Internet service providers have attempted to use short messages or e-mail when there is information they want to inform subscribers, but this is a type of spam, and even if they ask for their consent, It is difficult to deliver information to subscribers at low cost. Second, in order to search for the content desired by the subscriber, several steps of menu selection process are required after WAP access. This is inconvenient when considering the wireless Internet environment which is slower than the wired Internet and the screen of the terminal is small. Third, when the subscriber knows the URL of the content he / she wants and wants to search by inputting it, it is also very inconvenient to input the URL using the keypad of the mobile communication terminal. Fourth, the subscriber wants to select the most suitable medium to use the wireless Internet service according to the situation, but there is no appropriate method. For example, if you want to receive and retrieve useful information while driving a car, using ARS is more appropriate than WAP, and WAP would be more appropriate if you are listening to music. These problems appear to hinder the activation of wireless Internet service.Wireless Internet service providers can deliver information to subscribers in the right area at the right time and inexpensively without spam, and in response, There is an urgent need for a push medium that effectively induces use, and subscribers need a way to easily obtain useful information about content in the field they want and to search for the desired content through the medium with simple and simple operation if necessary. It is true.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the first object of the present invention is to provide a broadcast-type short message containing a summary information and callback information about the content to all terminals in a specific area The present invention provides a wireless Internet service system and method for delivering a content to a corresponding terminal using a WAP according to a request of a terminal user who reads summary information, that is, a short message broadcasting service using a WAP push means.

A second object of the present invention is to provide a broadcast-type short message containing summary information and callback information on content to all terminals in a specific region, and optionally receive a request of a terminal user who read the summary information through ARS. The present invention provides a wireless Internet service system and method for enabling a WAP-based wireless Internet service by performing WAP push to a corresponding terminal using a WAP push means (eg, a short message service).

A third object of the present invention is to provide a wireless Internet service system and method for carrying ARS callback information, WAP callback information, or both in a broadcast type short message and using the corresponding wireless Internet service according to a subscriber's choice. have.

It is a fourth object of the present invention to provide a wireless Internet service system and method for enabling linkage or conversion of a medium and a path that may be required in a process of using a wireless Internet service requested by a terminal after a message broadcast.

In addition, each callback type has a designated access button so that the type can be determined according to the button pressed by the terminal user.

Hereinafter, exemplary embodiments of a wireless Internet service system and method according to the present invention will be described in detail with reference to the accompanying drawings.

(Example 1)

1 is a diagram illustrating a configuration of a wireless Internet service system using CBS and WAP provided to all terminals in a desired area in connection with a short message broadcasting service according to the present invention. Specific apparatus 10, base station specific apparatus 20, broadcast message organizer 30, message broadcasting center 40, base station 50, terminal 60, WAP gateway 70, WAP content server 80 And a Unified Messaging Service (UMS) / Multimedia Server 90.

The broadcast area specifying device 10 is a device for designating a desired area according to the selection of a content provider to transmit a broadcast type short message to a terminal located in a predetermined region, and the base station specifying device 20 is a broadcast area specifying device 10. It is connected to the), and is a device for setting the set of base stations including the zone designated by the broadcast zone specific device (10). The zone designation method of the broadcast type short message by the broadcast area specifying apparatus 10 may, for example, first designate a position that is the center of the area in which the broadcast type short message is to be broadcasted to the terminal, that is, a broadcast request center position. A method of designating a service range of a broadcast short message is used. A base station specifying method by the base station specifying apparatus 20 may be a method of obtaining a broadcast area as a set of base stations including coverage, or a method of obtaining a set of base stations including coverage of a broadcast area designated by a combination of coverages of pre-calculated base stations. Use A more detailed description of the area designation method and the base station specification method of the broadcast short message will be described later with reference to FIGS. 2 and 3.

The broadcast message organizer 30 is located in the coverage of the base station based on the message broadcast related information (eg, broadcast time, broadcast channel, broadcast area, voice callback number, WAP callback URL, user message, etc.) requested by the content provider. It is a device for producing and organizing broadcast type short messages for transmission to all terminals. The broadcast type short message produced by the broadcast message organizer 30 is transmitted with each piece of information according to the type of callback. For example, to set the callback of a broadcast short message to WAP, the user data field of the broadcast short message includes a WAP callback identifier and a WAP callback URL indicating that the message is a callback to the WAP, in addition to the user message. If the callback of the broadcast short message is set to ARS, the callback number of the broadcast short message is designated in the callback number field. In addition, when the callback of the broadcast short message is set to WAP and ARS, the callback number may be specified in the callback number field at the same time as including the aforementioned WAP callback delimiter and WAP callback URL, and any information related to the callback may be used. (Eg, type of callback, order of callback execution, etc.). In addition to the WAP callback delimiter and WAP callback URL, the user data field may contain the length of the WAP callback URL and the user message to be sent to the terminal. The user message may include a character string as well as a JPEG, GIF, BMP or similar form. The image may be multimedia data such as an image encoded by a method, a melody produced for a ringtone of a terminal, a sound or voice encoded by a method of WAV, MP3, or the like. If the message containing such multimedia data exceeds the maximum length of user data accommodated by one broadcast short message, the broadcast message organizer or the message broadcasting center transmits the messages in a plurality of broadcast short messages in sequence and The received terminal may be summed and then decoded through the output device of the terminal such as a display, a buzzer or a speaker.

The message broadcasting center 40 is connected to the base station specifying apparatus 20 and the broadcast message organizer 30, and transmits a broadcast type short message including broadcast information to the base station 50 set by the base station specifying apparatus 20. It serves to transmit. Here, although the base station specifying device 20 and the broadcast message organizer 30 connected to the message broadcasting center 40 are illustrated as separate devices, these are illustrated to separately describe the roles for each component. It may be included in the message broadcast center 40, and the broadcast area specifying device 10 and the base station specifying device 20 may be designed as a single device.

The base station 50 is connected to the message broadcasting center 40, and transmits the broadcast type short message transmitted from the message broadcasting center 40 to the broadcasting area set by the broadcasting area specifying apparatus 10, and links with the terminal. It serves to control the radio or telecommunications. The base station 50 may include a base station controller (not shown) for receiving a broadcast short message transmitted from the message broadcasting center 40 and converting the received short message into a data burst message of a signaling channel. In addition, since the broadcast short message transmitted to one terminal may be overlapped (since the terminal may be overlapped with each base station when multiple base stations transmit the broadcast short message at the same time), each base station It is preferable to transmit a broadcast type short message so that the terminal can receive a single data even in an area where broadcast areas overlap. As the mobile communication method that can be used, code division multiplexing (CDMA), frequency division multiplexing (FDMA), time division multiplexing (TDMA), etc. are possible. It refers to a method of realizing multiple access so that a frequency division multiplexing method is a method of transmitting different signals on a plurality of carrier frequencies through a single transmission path, and a time division multiplexing method uses a time interval at a predetermined interval. It is a method of transmitting different signals in each time slot. In the present invention, it is possible to select and use any one of them in consideration of local characteristics and efficient characteristics, but it is preferable to use the code division multiplexing method taken in our country.

The terminal 60 is wirelessly interconnected with the base station 50, and the terminal 60 of the present invention is equipped with a broadcast type short message browser and a WAP browser for wireless communication that can use a short message broadcasting service and a wireless Internet service. Use a terminal. This category of wireless communication terminals also includes terminals for International Mobile Telecommunications (IMT) -2000 using cellular (800 MHz) or PCS (1.8 GHz) and higher frequency (2 GHz) bands. Although only one base station 50 and one terminal 60 are shown in FIG. 1, it is apparent to those skilled in the art that a plurality of base stations 50 and a terminal 60 may be combined.

The WAP gateway 70 is interconnected with the base station 50, and is located between the terminal 60 and the WAP content server 80 to convert between the WAP protocol and the WWW protocol. Mobile communication that enables wireless data communication between the base station 50 and the WAP gateway 70 such as a base station controller (not shown), an exchanger (not shown), and a data network interworking device (IWF). There may be network devices, and these devices may be different according to the characteristics and design of the mobile communication network and are omitted because they are not devices that are specialized or changed for the implementation of the present invention. The wireless Internet service request of all terminals 60 passes through the WAP gateway 70, and the WAP gateway 70 requests the service again through the existing wired Internet network. Subsequently, the WAP gateway 70 receives a response from the WAP content server 80 and provides the WAP to the terminal 60 that originally requested the service. In other words, the WAP gateway uses WSP (Wireless Session Protocol), WTP (Wireless Transaction Protocol), WTLS (Wireless Transport Layer Security), and WDP (WDP) as components of the WAP protocol stack. Switch between HTTP and TCP / IP. The WAP architecture provides a scalable protocol environment and a hierarchical overall network structure for developing terminal applications. In addition, the WAP gateway 70 includes a content encoder and a content decoder to convert the WAP content into a concise coded format to reduce the data size on the network, or to convert the WAP content into data before being encoded again. Perform the function of converting. If the WAP content server 80 provides WAP content made of WML, the WAP gateway 70 directly transmits the WAP content to the terminal 60 through the base station 50, and the WAP content server 80 makes the web content made of HTML. If provided, the HTML filter converts the WML to the terminal 60 through the base station 50.

WAP is an industry standard for the efficient transmission of Internet-centric wireless data services in a wireless environment. The purpose of WAP is to enable the use of Internet services in digital cellular telephones and wireless terminals and to operate in other types of wireless network technologies. Developing standards and developing content and application technologies that can be used in other types of wireless network technologies and equipment. WAP content and applications are created based on the web content format, and WAP content is transmitted using WTP, a communication protocol built on the web communication protocol. The wireless terminal uses the user interface microbrowser to navigate the entire site, which has similar functionality to the standard web browser used on the web. WAP content types and protocols are optimized for the telecommunications market and all portable wireless devices, and WAP uses proxy technology for seamless connectivity between wireless URLs and the WAP content server 80.

The WAP content server 80 is interconnected with the WAP gateway 70, provides WAP content to the terminal 60, and collects and collects desired information in association with other media or paths at the request of the terminal 60. Converts the information into a predetermined format (eg, WML, HTML, etc.) and transmits the converted information to the WAP gateway 70. In addition, the terminal 60 operates and controls a program for smoothly providing a wireless Internet service.

The UMS / multimedia server 90 is interconnected with the WAP content server 80, and transmits and receives all data through a single service regardless of the type of the terminal 60 for all types of messages such as voice, fax, and e-mail. UMS can be executed, and various resources distributed on the Internet, such as stored multimedia data, real-time multimedia input / output device or multimedia data, real-time multimedia input / output device or multimedia related processes, are accessed and processed, and then distributed to the distributed environment. It plays a role of distributing. UMS is a unified messaging service that enables users to communicate more conveniently by integrating various communication methods such as telephone, fax, and mobile phone into one email. UMS includes e-mail to e-mail to view incoming e-mail on the web or POP3, e-mail to voice to receive e-mail with voice only on the phone, voice to voice to function as a voice mailbox, fax to It includes fax to e-mail to send an e-mail after accessing the main number, fax to fax to fax a document arrived by fax, and e-mail to fax to fax an e-mail. In addition, in order to process multimedia information on the Internet, a multimedia database system technology capable of effectively storing and managing a large amount of multimedia data and a hypermedia system technology providing a convenient search environment should be based on the remote information. In addition, a multimedia authoring environment capable of creating a work, a collaborative working environment where several workers can collaborate, and a multimedia information exchanging environment for exchanging necessary information should be provided.

2 is a diagram illustrating a base station specific concept according to the present invention, and each of the base stations 100, 102,..., 138 has its own coverage 100, 102,..., 138. The coverage shown in the figure is hexagonal, but this is only a simplification to illustrate the concept of a base station. The actual coverage is circular, and each coverage is shown as not overlapping with an adjacent coverage, but in practice there are many overlapping regions. It will be readily apparent to those skilled in the art.

First, the content provider designates a position that is the center of the domain for the desired broadcast type short message, that is, the broadcast request center position 200. Here, the broadcast request center position 200 is preferably designated as the point where the business of the content provider is located. The content provider then specifies the transmission range of the desired broadcast type short message (i.e., the broadcast area 250). For example, if the content provider wants to transmit a broadcast short message to all terminals within 3 km from the broadcast request center location 200, the broadcast area 250 will be inside the circle shown in FIG. Subsequently, the base station specifying apparatus 20 uses a geographic information system or the like to determine the minimum set of base stations included in the coverage of the broadcast area 250 (104, 110, 112, 114, 120, 122, 124, in the case of FIG. 2). 126, 132, 134). Thereafter, the broadcast short message is transmitted through the base stations 104, 110, 112, 114, 120, 122, 124, 126, 132, and 134 specified as described above, and the coverage 104, 110, 112, 114, 120, 122, 124, 126, 132, 134 are received and displayed by all terminals operating in. The broadcast request center location 200 and the broadcast area 250 may be changed by selection of a content provider.

3 is a view showing an example of a broadcast zone specification according to the present invention, there is a method for determining the broadcast zone and base station by the selection of the content provider and a method using a pre-calculated reference table, Figure 3 is the latter method It is a figure explaining an example. As mentioned above, the broadcast area specifying device 10 and the base station specifying device 20 may be designed in one block, and either of the zone storage 300 and the base station set storage 350 may be provided. Assume that it is included.

First, a plurality of dictionary zones are stored in the district storage unit 300 in a meaningful area such as a predetermined administrative area or a commercial area, and the base station set storage unit 350 is stored in the regional storage unit 300. It stores a minimum set of base stations with coverage for each area. Here, the prior zone may be divided into city or county zones, old zones, or east zones, and the base station set may preset base stations to be transmitted by the broadcast type short message through base station coverage corresponding to pre-stored broadcast zones. Can be calculated and stored in the form of a lookup table.

Referring to the drawings, base stations 1002, 1004, and 1006 are correspondingly stored in Samseong-dong, Gangnam-gu, and base stations 1012, 1014, and 1016 are correspondingly stored in Daechi-dong. At this time, the coverages of the base stations 1012, 1014, and 1016 include Samsung-dong, and the coverages of the base stations 1012, 1014, and 1016 include substitution-dong. Of course, this is shown for the purpose of illustration, the number of each base station corresponding to one wing may be stored differently, and the base station sets stored for the different wing may include base stations common to each other.

An operation state of an embodiment according to the present invention as described above will be described with reference to the accompanying drawings.

4 is a flowchart illustrating the operation of the wireless Internet service system using the CBS and WAP according to the present invention, Figures 4a and 4b is an exemplary screen showing a process of executing the wireless Internet service using the CBS and WAP according to the present invention to be.

First, the wireless Internet service system specifies the broadcast zone and the base station according to the request of the content provider (S402). That is, when a broadcast request center location and a broadcast area are designated according to a content provider's request, the broadcast area specifying device and the base station specifying device select a set of base stations for the broadcast request center location based on the reference table shown in FIG. The content provider specifies the desired broadcast zone and base station. Of course, the specification of the broadcast area and the base station can be newly specified by the broadcast area specifying device and the base station specifying device without referring to the reference table. Next, the message fragment growth value is broadcasted for transmission to all terminals located in the coverage of each base station based on the content provider's request (e.g., broadcast time point, broadcast channel, broadcast area, voice callback number, user data field, etc.). Produce and organize the type short message (S404). In this case, if the callback of the broadcast short message is to be set to WAP, a callback delimiter (that is, a WAP callback delimiter) and a callback URL (that is, WAP callback) indicating that the message is called back to WAP in the user data field of the broadcast short message A short message including a URL). Such broadcast type short messages may be organized prior to the specification of the broadcast area and the base station. Here, the callback delimiter is for specifying the type of callback, and the callback URL is for specifying the path of the callback when the terminal user requests the callback.

The organized broadcast short message is transmitted to the message broadcasting center (S406), and the message broadcasting center transmits the broadcast short message to all the base stations specified in step S402, and each base station receives the broadcast short message. They transmit the broadcast short message to all terminals located in their coverage (S408). The broadcast short message is transmitted at a time desired by the content provider, and the interface between the message broadcast center and the base station may be variously implemented according to the configuration of the mobile communication network.

All terminals located in the coverage of the base station receive the broadcast short message transmitted from the base station, restore the original message transmitted by the message organizer, and display the same. The terminal may display the WAP callback URL on the screen in addition to the received message. An exemplary diagram of the broadcast short message displayed on the screen of the terminal is illustrated in FIG. 4A. The terminal user looks at the displayed content and decides whether to request the desired information. For example, when a terminal user wants to request information, the user generally presses the call button of the terminal. However, if both ARS and WAP callbacks are possible, the ARS callback sets the call button by setting a specific button (for example, a WAP button) in the terminal. And WAP callbacks can be set to press the WAP button.

When the terminal user connects, the WAP content server provides the corresponding information to the corresponding terminal using the WAP (S410). In order to display the contents delivered to the terminal on the screen of the terminal, a dedicated browser is required, and a plurality of dedicated buttons must be provided on the terminal for content navigation, and the page-to-page movement can be simply performed. WAP uses WML (or HDML), which is different from HTML on the Internet, and much of the content on the web is passed through the mobile phone wireless data network via the WAP gateway on the Internet, as mentioned above, to reach the terminal. For this purpose, it transmits using a specific transport protocol. On the mobile phone network, data is transmitted through HDTP (Handheld Device Transport Protocol) or a corresponding WAP protocol, as if the homepage is opened in HTTP format on the Internet. Data passing through the WAP gateway is converted into binary files, which has the advantage of lighter capacity and less burden on transmission. When the information is transmitted from the WAP content server to the terminal, WAP content made of WML (or HDML) is sent directly to the terminal through the WAP gateway, and WAP content made of HTML is converted into WML by the WAP gateway and transmitted to the terminal. . An exemplary diagram in which content transmitted from the WAP content server to the terminal by the callback request of the terminal is displayed on the screen of the terminal is illustrated in FIG. 4B. When the terminal user sees the displayed information and wants more detailed information through another medium or route, the terminal user instructs an execution command by pressing an appropriate command (for example, pressing a call button or moving to a corresponding menu by pressing a call button or a navigation key) according to the type of message being delivered. Etc.).

When the terminal user requests a connection to request more detailed information through another medium or path, the WAP content server transmits desired information in association with the corresponding medium or path (S412). That is, the WAP content server associates the terminal with the URL when the terminal attempts to access the WAP with the WAP callback URL included in the WAP push message. At this time, the WAP push means may be a short message service (SMS) according to the communication means provided by the mobile communication network, or may be a data communication service when providing a data service that can be received. When the WAP push message is transmitted in the form of data communication, since the connection between the WAP content server and the terminal is already established, mutual information can be exchanged without additional call connection work. The data transmitted through the medium or path associated with the terminal may be any kind of data that can be transmitted through communication such as e-mail, fax, voicemail, short message, character, multimedia file, multimedia stream, and execution code. . Here, the type of WAP push is expressed as an SMS message in which the WAP homepage URL is embedded in the user data field of the message. However, the method of using a CBS (Cell Broadcasting Service) or a data call when data can be used may be used. Can be.

(Example 2)

5 is a view showing the configuration of the wireless Internet service system using the CBS, ARS and WAP according to the present invention, the configuration of the wireless Internet service system using the CBS, ARS and WAP is a portion of the wireless using the CBS and WAP of Figure 1 It is the same as the configuration of the Internet service system. Accordingly, like parts have been given the same reference numerals, and descriptions of the same parts are omitted herein to avoid unnecessarily obscuring the claims of the present invention.

Wireless Internet service system using the CBS, ARS and WAP according to the present invention, in addition to the components of the wireless Internet service system using the CBS and WAP switch 100, voice automatic response system (ARS) 110, WAP push / short message It further comprises a transmission device 120 and a short message service center 130. When the broadcast short message is organized by the broadcast message organizer, when the callback type of the terminal is ARS, a broadcast type short message is organized by specifying a corresponding callback number in the callback number field, and the callback type of the terminal is WAP. Contains a WAP callback delimiter and a WAP callback URL in the user data field, and includes a callback number, a WAP callback delimiter, and a WAP callback URL when the terminal's callback type includes ARS and WAP simultaneously. Organize broadcast short messages.

The exchange 100 is connected to the base station 50, and serves to connect the terminal and the ARS when the callback type of the terminal is ARS. That is, when the callback type is ARS, since the corresponding callback number is specified in the callback number field of the broadcast short message, the ARS corresponding to the callback number is connected to the terminal. The ARS is connected to the exchange 100 and, when connected to the terminal 60 by the exchange 100, serves to provide voice information required by the terminal 60 to the terminal 60.

The WAP push / short message transmission device 120 is connected to the ARS 110, and when the terminal user wants to obtain additional information through a service other than voice information, the WAP push / short message transmission device 120 converts the information into a short message or a WAP push message. It converts and transmits. Between the ARS 110 and the WAP push / short message transmitter 120, there is a device such as an integrated service organizer (not shown), which provides message notification, message transmission at timed intervals, transmission of multiple messages with time periods, and the like. More complex services can be performed. The short message service center (SMSC) 130 performs a role of providing a communication service for delivering in the form of a limited size character (ie, short text) to the terminal. That is, a short message transmitted to a terminal user that cannot be received at any moment is stored and transmitted until the user can receive it, and also delivered to the user who is in a call.

Referring to the operation state of another embodiment according to the present invention as described above with reference to the accompanying drawings as follows.

FIG. 6 is a flowchart illustrating an operation of a wireless Internet service system using CBS, ARS and WAP according to the present invention, and FIG. 6A is a screen diagram illustrating a process of executing a wireless Internet service using ARS and WAP according to the present invention. to be.

First, the wireless Internet service system specifies the broadcast zone and the base station according to the request of the content provider (S602). That is, when a broadcast request center location and a broadcast area are designated according to a content provider's request, the broadcast area specifying device and the base station specifying device select a set of base stations for the broadcast request center location based on the reference table shown in FIG. The content provider specifies the desired broadcast zone and base station. Of course, the specification of the broadcast area and the base station can be newly specified by the broadcast area specifying device and the base station specifying device without referring to the reference table. Next, the message fragment growth value is broadcasted for transmission to all terminals located in the coverage of each base station based on the content provider's request (e.g., broadcast time point, broadcast channel, broadcast area, voice callback number, user data field, etc.). Produce and organize the type short message (S604). Such broadcast type short messages may be organized prior to the specification of the broadcast area and the base station. When the broadcast short message is organized by the broadcast message organizer, when the callback type of the terminal is ARS, a broadcast type short message is organized by specifying a corresponding callback number in the callback number field, and the callback type of the terminal is WAP. Contains a WAP callback delimiter and a WAP callback URL in the user data field, and includes a callback number, a WAP callback delimiter, and a WAP callback URL when the terminal's callback type includes ARS and WAP simultaneously. Organize broadcast short messages.

The organized broadcast short message is transmitted to the message broadcast center (S606), and the message broadcast center transmits the broadcast short message to all the base stations specified in step S602, and each base station that has received the broadcast short message is transmitted. They transmit the broadcast short message to all the terminals located in their coverage (S608). The broadcast short message is transmitted at a time desired by the content provider, and the interface between the message broadcast center and the base station may be variously implemented according to the configuration of the mobile communication network.

All terminals located in the coverage of the base station receive the broadcast short message transmitted from the base station, restore the original message transmitted by the message organizer, and display the same. In addition to the received message, the terminal may display the ARS callback number or the WAP callback URL on the screen. An exemplary diagram of the broadcast short message displayed on the screen of the terminal is illustrated in FIG. 4A. The terminal user looks at the displayed content and decides whether to request the desired information. For example, when a terminal user wants to request information, the user generally presses the call button of the terminal. However, if both ARS and WAP callbacks are possible, the ARS callback sets the call button by setting a specific button (for example, a WAP button) in the terminal. And WAP callbacks can be set to press the WAP button.

If a user wants to provide WAP content using WAP callback to a user who has an existing terminal capable of ARS callback for a broadcast short message, the system sends a broadcast short message containing a specific ARS callback number to the terminal and the terminal user If you press the call button to request information, the call is connected to the ARS number. At this time, the ARS or any system connected to the ARS transmits the WAP push message including the URL of the desired WAP content to the terminal connecting the call. At this time, the ARS may provide voice information including information on the provision of the WAP push message or advertisement or information, and the user may use the ARS's IVR (Interactive Voice Response) function to provide information in a desired manner such as ARS or WAP. You can make a choice to get. In the case of a terminal capable of both ARS callback and WAP callback for a broadcast short message, as described in (Example 1), the subscriber's callback button is selected or preset in the terminal or preset in the terminal due to the function of the terminal. Content provided in the desired media by the content can be provided. That is, the combination of the terminal function and the system function [broadcast short message transmission-> ARS callback-> voice content provision], [broadcast short message transmission-> WAP callback-> WAP content provision], [broadcast short message transmission] -> ARS callback-> WAP push message transmission-> WAP callback-> WAP content delivery], [broadcast short message transmission-> ARS callback-> content delivery using IRS function of ARS-> voice content provision or WAP push message transmission and WAP content provision by WAP callback].

If the callback type is ARS, when the terminal user issues an information request command (i.e., presses a call button), the exchange connects the terminal and the ARS (S610), and if the terminal user's selection according to the IVR function of the ARS is ARS, The stored ARS content is provided to the terminal (S612) so that the terminal user can listen to the information by voice. For example, when the terminal user attempts to make a voice connection, the ARS outputs a voice message such as 'A WAP push message is sent, so check when the message arrives and press the call'. If the terminal user's selection according to the IVR function of the ARS is WAP, the WAP push / short message transmitter transmits the WAP push message to the terminal (S614), and provides the WAP content when the terminal user performs the WAP callback (S616). .

If the callback type is WAP, when the terminal user issues an information request command (that is, presses a call button or a specific button such as a WAP button or a WAP soft key), the exchange and the WAP gateway connect (S618) the terminal to the WAP content server. The WAP content stored in the callback URL is provided to the terminal (S620). In order to display the contents delivered to the terminal on the screen of the terminal, a dedicated browser is required, and a plurality of dedicated buttons must be provided on the terminal for content navigation, and the page-to-page movement can be simply performed. WAP uses HDML, which is different from HTML on the Internet (which is called WML in WAP), and allows many content on the Web to reach mobile devices via the WAP gateway on the Internet via the WAP gateway, as mentioned above. do. When the information is transmitted from the WAP content server to the terminal, the WAP content made of WML is transmitted directly to the terminal through the WAP gateway, and the WAP content made of HTML is converted into WML by the WAP gateway and transmitted to the terminal. An exemplary diagram in which content transmitted from the WAP content server to the terminal by the callback request of the terminal is displayed on the screen of the terminal is illustrated in FIG. 4B. When the terminal user sees the displayed information and wants more detailed information through another medium or route, the terminal user can issue an appropriate command (for example, pressing a call button or navigating to a menu using a navigation key to instruct an execution command). .

When the callback type is ARS and WAP, the terminal is connected to the ARS or the terminal by the callback URL according to the preset callback type selected by the terminal user (S622). That is, if the callback number is specified in the callback number field and the WAP callback identifier is included in the user data field at the same time, the voice connection may be attempted first or the WAP connection may be attempted first when the call button is pressed by the terminal user. In addition, a connection selected by the terminal user may be preferentially attempted using the terminal itself. If the voice connection is attempted, the process proceeds to the step S610 and the subsequent steps are repeated. If the WAP connection is attempted, the process proceeds to the step S618 and the subsequent steps are repeated to the terminal user. Transmit (S624).

After the above steps (S612, S616, S620, S624), if the terminal user requests access to request more detailed information through another medium or path, the terminal user transmits the desired information in association with the medium or path (S626). . In addition, if the terminal user wants to obtain additional information or data in another medium or another path as a result of using the WAP content, the WAP content server sends a command to the UMS / Multimedia server or a short message transmission device. Data can be transmitted in association with a medium or a path.

The ARS can be configured to allow a terminal user to select an associated medium or path through voice information and to input various data for transmission of the information. When there is only one associated medium or path, a simple notification voice message or voice You can connect directly without a message. For example, the voice message says 'Press 1 to listen to the details and receive the password as a short message, 2 to search the WAP for details and 3 to receive the fax details.' To instruct the terminal user to select and print, or 'I'm currently sending that information in a short message. You can configure your service to either output a voice message or wait for WAP push immediately without a voice message. The data transmitted through the medium or path associated with the terminal may be any kind of data that can be transmitted through communication such as e-mail, fax, voicemail, short message, character, multimedia file, multimedia stream, and execution code. . Here, the type of WAP push is expressed as an SMS message in which the WAP homepage URL is embedded in the user data field of the message.However, a method of using a CBS (Cell Broadcasting Service) or a data call when the data can be received is referred to as a data call. And the like can be used.

The above description is only for explaining one embodiment, and the present invention is not limited to the above-described embodiment and can be variously changed within the scope of the appended claims. For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.

As described above, according to the wireless Internet service system and method according to the present invention, by providing the organized broadcast short message to all the terminals in a specific broadcasting area, the content provider delivers the desired information to the terminal user in a push manner and is required. By easily accessing the contents in response to the time, it is possible to maximize the profits from providing the contents, and the terminal user can receive the information corresponding to the user's arbitrarily selected interests as the summary contents at the appropriate time in the appropriate region, and the detailed contents. If you want a simple and easy operation has the effect that you can easily provide detailed content through the desired media.
