## Background
TECHNICAL FIELD
The present invention relates to a method and system for receiving data by using SMS and wireless Internet.
BACKGROUND ART
Recently, a Short Message Service, SMS, has been broadly used between mobile communication users. Also, a wireless Internet has been used more and more.
The SMS facilitates that a sender sends a short message by using mobile communication service to a recipient, then the recipient can receives the short message.
The SMS may be implemented by two ways. The one way is that a sender connects a web site using Internet and transmits a short message to a recipient using mobile communication terminal. The other way is that a sender using mobile communication terminal sends a short message to a recipient using mobile communication terminal.
To receive the short message, a separate terminal is needed. Also, the terminal may receives the short message in the middle of conversation. If a mobile communication terminal may not receive the short messages because of being turned off the power supply of the terminal, the short messages may be stored in a Short Message Service Center, SMSC. After that time, if the power supply is turned on, a message for indicating the arrival of the short messages is displayed on the display device. The terminal may receive the short messages stored in the SMSC according to a predetermined way. Also, recently, a sender, a user of one communication service company, may send short messages to a recipient, a user of another communication service company. Because a short message made of maximum 224 characters of the English may be send by using the SMS technology, the SMS technology has been used for providing weather information, stock information, transacting e-business, and other fields.
With the SMS methods, data of large size (for example, moving pictures) may not be transmitted, because the maximum size of data for transmitting is 224 characters of the English.
By using the wireless Internet technology, data provided by server may be transmitted to a user terminal via an Interworking Function, IWF, and a base station. A user may confirm the received data by handling a user terminal. Otherwise, data transmitted from the user terminal may be transmitted to the server via the IWF and the base station. The IWF has a modem and PPP server. Accordingly, users may receive or transmit data using only mobile communication terminal.
The WAP gateway converts data in HTTP protocol pattern into wireless data. If the function of the WAP gateway is embarked in the user terminal, separate WAP gateway may not be needed. Namely, a mobile communication terminal embarking the ME (Mobile Explorer) developed by MS may execute the function of the WAP gateway.
However, if users wish to use the data service by using the wireless Internet, they should connect the communication channel by handling their terminals and request the data service. Also, the service provider may not provide the data service for the users arbitrary, before the communication channel is connected by the users.

For example, the data field divider 440 may divide the short messages into a service identifier field, a first site information field, a second site information field, and similar fields. The service identifier field may store service identifiers. The first site information fields may store a first application protocol, a first URL and similar data. Also, the second site information fields may store a second application protocol, a second URL and similar data. The size of each field may preferably be assigned in advance.
When the following short message is received, 0003737: http://www.n016.com/info/info.html: game://172.29.148.180/games/tetris.game, the data field divider 440 may divide the short message into the follows:
the service identifier: 0003737;
the first application protocol: http;
the first URL: www.n016.com/info/info.html;
the second application protocol: game;
the second URL: 172.29.148.180/games/tetris.game.
From the data divided by the data field divider 440, the user terminal may recognize a short message that comprises the service identifier (0003737) for the user 400, web site information and information for games.
The service identifier determiner 450 may determine the sort of service that the user 400 has subscribed in advance by using the service identifier divided by the data field divider 440. If the user subscribes to the service provider 100, he may be provided the service identifier. The service provider 100 may store and manage the service identifier provided for the user 400. Also, the service identifier determiner 450 may omit the step of determining whether or not the user 400 is subscriber, because the service provider 100 may transmit the short messages only to the user 400 provided the service identifier.

The data receiving system divides the received short message into data fields (Step 520). The data fields may comprise the service identifier fields, site information fields. Also, the size of each data field is preferably pre-determined.
The data receiving system determines the sort of service that the user 400 has subscribed in advance by using the service identifier (Step 530). The service identifier may be managed by the service provider 100 or be stored in the user terminal 410.
The data receiving system determines whether or not the application protocol comprised in the received short message is registered (Step 540). The application protocol comprised in the received in the short message should be registered in the user terminal 410 in advance. If the application protocol is not registered in the user terminal 410, the user terminal 410 may not connect a web site by using the URL in correspondence with the application protocol provided by the service provider 100. In general, the user terminal 410 may embark the IP channel connecting program in correspondence with the HTTP application protocol. Otherwise, the user terminal 410 may have the IP channel connecting program in correspondence with other application protocol (for example, game, sports, news, stock). Accordingly, for connecting to the service provider 100 in correspondence with various application protocols, the IP channel connecting program in correspondence with each application protocol may preferably be embarked in the user terminal 410. If the IP channel connecting program is embarked in the user terminal 410, the application protocol list in correspondence with the IP channel connecting program may be stored in the user terminal 410 or be updated. The user terminal 410, the data receiving system, determines whether or not the application protocol transmitted from the service provider 100 is comprised in the application protocol list.
When the application protocol in the short message is comprised in the application protocol list, the data receiving system may execute the IP channel connecting program (Step 550). The IP channel connecting program may preferably be embarked in the user terminal 410 in advance.
The data receiving system may connect to a web site by using the URL in correspondence with the application protocol provided by the service provider 100, simultaneously with being executed the IP channel connecting program (Step 560). Namely, if the IP channel connecting program is executed, the data receiving system may transmit the URL to the IP channel connecting program and connect the web site by using the URL.
Accordingly, the data receiving system may connect the web site by using the URL, and request data service for the service provider 100. Also, the data receiving system may receive the data transmitted from the service provider 100 and display them on a display device.
