Hereinafter, a portable terminal and a wireless internet access method according to the present invention will be described in detail with reference to the accompanying drawings.

The basic principle of the present invention is to enable wireless internet transactions of a mobile terminal through wireless communication with an external RF card.

1 is a view schematically showing the configuration of a system for a wireless Internet transaction of a mobile terminal according to the present invention.

Referring to FIG. 1, a system for a wireless internet transaction includes a web server 10, a wireless internet gateway 20, an RF card 30, and a portable terminal 40.

The web server 10 drives a web site and transmits data such as web documents to a client connected to the web site.

The wireless internet gateway 20 is located between the wireless internet terminal, for example, the mobile terminal 40 and the web server 10. The wireless internet gateway 20 is a system that allows the mobile terminal 40 to access the web server 10 using a wireless internet browser and download contents. The wireless internet gateway 20 is an essential element for downloading a web document using a wireless internet protocol.

RF card 30 is a plastic plate, such as IC chip components are embedded, the IC chip is integrated with a microprocessor, such as a CPU, card operating system, memory, security module, and the like. Such IC chips can store, modify, and delete programs. Therefore, the IC chip may have a function such as electronic money, a traffic pass, or the like depending on the program.

The RF card 30 can store more information than the existing magnetic card using a magnetic wire due to the IC chip, and is also excellent in stability. That is, since the RF card 30 can store and use a large amount of information such as personal information such as bank account, social security number, etc. as well as user or transaction information in the memory, it is possible not only as a simple electronic money but also various applications. The RF card 30 is a contactless card. When the RF card 30 is located within a predetermined distance from a terminal such as the portable terminal 40 and the RF card reader, the card information can be read by the terminal. Since the contactless card cannot supply the voltage from the outside, the inductive current is obtained by using the coil embedded in the card. The contactless card also includes a simple wireless communication circuit for data input and output with the terminal.

The mobile terminal 40 is a mobile terminal equipped with a wireless internet browser, and is connected to the web server 10 through the wireless internet gateway 20 to receive contents. The mobile terminal 40 uses a slightly reduced WAP (Wireless Application Protocol) browser than a browser on a personal computer due to limited resources, such as memory, screen and communication speed. Here, WAP is a global standard protocol for Internet information retrieval in mobile terminals such as mobile phones, personal digital assistants (PDAs), etc. with the development of wireless communication. The portable terminal 40 includes an RF module that can recognize the RF card 30 and receive information therefrom. Therefore, the portable terminal 40 can easily conduct transactions on the wireless Internet by using the external RF card 30 through the RF module. In this case, in order to perform a wireless Internet transaction using the RF card 30, authentication for a service supported by the RF card 30 is required.

The service authentication method includes an offline authentication method and an online authentication method. The offline authentication method is a method of authenticating inside the mobile terminal 40, and is an authentication method using authentication information stored in advance for a service of the RF card 30. On the other hand, the online authentication method is a method of authenticating in connection with a server (not shown) that provides a service of the RF card (30). The mobile terminal 40 can reliably complete a transaction on the wireless Internet through this service authentication procedure.

FIG. 2 is a block diagram schematically illustrating a configuration of the portable terminal of FIG. 1.

Referring to FIG. 2, the mobile terminal 40 includes an RF module 50, an authentication processor 60, and a user interface 70.

The RF module 50 includes an RF transceiver 51 and an RF data processor 52.

When the external RF card is located within a certain distance, the RF transceiver 51 recognizes the RF card and performs wireless communication through the RF antenna. That is, the RF transceiver 51 is a part for transmitting and receiving data with the RF card. Therefore, the RF transceiver 51 transmits the data received from the RF card to the RF data processor 52, and transmits the data received from the RF data processor 52 to the RF card. The RF transceiver 51 may perform wireless communication when the wireless Internet browser mounted on the portable terminal is activated. The RF transceiver 51 may recognize various types of RF cards together.

The RF data processor 52 transmits the information on the service authentication process among the data received from the RF transceiver 51 to the authentication processor 60.

The RF data processor 52 changes and processes data received from the RF transceiver 51 into data required on the wireless Internet after service authentication from the authentication processor 60. In addition, the RF data processing unit 52 changes and processes the data received on the wireless Internet into data for transmission to the RF card and transmits the data to the RF transmission / reception unit 51.

The service authentication processor 60 is a part that processes the authentication of the chip service supported by the chip of the RF card. The service authentication processing unit 60 includes an offline authentication processing unit 61 and an online authentication processing unit 62.

The offline authentication processor 61 is a module for authenticating a chip service in a mobile terminal, and includes an encryption key and an encryption algorithm of a service provider. The offline authentication processor 61 receives chip data from the RF data processor 52 and transmits the authentication result to the RF data processor 52.

The online authentication processing unit 62 is a module for authenticating a chip service by connecting to a server providing a service and is a module for online communication with the corresponding server. If the online authentication processor 62 fails to authenticate the chip service in the offline authentication processor 61, the online authentication processor 62 receives the chip data from the RF data processor 52 and transmits the authentication result to the RF data processor 52.

The user interface unit 70 is connected to the RF data processor 52 to display a process inside the portable terminal 40 on the screen. Therefore, the user can easily know the transaction status and RF card information through the user interface 70.

The portable terminal 40 may use the chip service of the external RF card 30 by configuring the RF module 50 capable of wireless communication therein, thereby facilitating wireless internet transactions. Therefore, the wireless internet transaction can be performed without inserting the chip into the portable terminal 40, thereby eliminating the inconvenience caused by mounting and dismounting the chip. In addition, the mobile terminal 40 may recognize a plurality of RF cards supporting different services together, and may select an RF card according to a service to be used.

3 is a flowchart illustrating a method for accessing a wireless Internet of a mobile terminal according to the present invention.

Referring to Figure 3, first, access to the wireless Internet (S10).

The user can access the wireless Internet site through the wireless internet browser.

Subsequently, the RF card located within the communication possible distance is recognized (S20).

Specifically, when a user wants to make a transaction on a specific wireless Internet site, the user places the RF card within a distance capable of communicating with the portable terminal. Then, the portable terminal recognizes the RF card located within the communication range. Here, the distance at which communication is possible is a distance that the portable terminal can recognize the RF card, for example, may be within 10 cm. In this case, the mobile terminal may recognize a plurality of RF cards located within a communication range. Therefore, the user can select a desired RF card according to the service supported by the RF card.

Meanwhile, before recognizing the RF card, the method may further include selecting a transaction using the RF card among various transaction payment means. In addition, after recognizing the RF card, the method may further include checking whether the recognized RF card is used. At this time, if the use confirmation of the RF card is selected, the next step for the transaction proceeds. However, if you choose to deny the use of the RF card, the transaction is stopped and you are redirected to the existing wireless Internet screen.

Subsequently, the chip service of the RF card is authenticated (S30, S31, S32).

In detail, when a user purchases an item using an RF card at a wireless internet shopping site, an authentication procedure for a credit card service supported by the recognized RF card is performed.

Authentication of the chip service of the RF card may be performed using an offline or online authentication method.

First, the mobile terminal performs an offline authentication method. The offline authentication method is a method of authenticating in a mobile terminal, and is a method of authenticating a chip service using an encryption key and an encryption algorithm provided in advance from a service provider, that is, an affiliate.

However, if the chip service is not authenticated by the offline authentication method, the online authentication method is performed. The online authentication method is a method of accessing a server of a service provider from a mobile terminal and authenticating chip service from the server.

Subsequently, the service result using the RF card is transmitted over the wireless Internet (S40).

Specifically, when the authentication for the service supported by the RF card is completed, the authentication result is transferred to the wireless internet shopping site, for example, on the wireless internet. Then, the payment details are written, and the payment results are sent to the wireless internet shopping site. Thereafter, the wireless internet transaction can be completed by confirming that the transaction was successfully performed from the site.

The mobile terminal displays the wireless Internet transaction status and RF card information through the user interface unit. Accordingly, the user can quickly and stably perform wireless internet transactions.
