Korean Patent Publication No. 2005-15531

The present invention relates to a method of reading telephone number information stored in an RFID tag and calling a phone number in a mobile communication terminal and a method of reading telephone number information stored in several RFID tags at once.

When a call is sent from a conventional mobile communication terminal, a method of inputting a phone number includes a method of directly inputting a keypad, a method of inputting a shortcut key, a method of inputting a phone number search, and the like. In order to be able to input a phone number through a phone number search, it is necessary to store the phone number in the phone book of the mobile communication terminal before calling. Conventionally, such a phone number input process is performed by a user inputting one by one through a keypad.

However, Korean Patent Publication No. 2005-15531 proposes a technology for converting data stored in an RFID tag of a business card into address book data of a mobile communication terminal and storing the data in a mobile communication terminal.

RFID (Radio Frequency IDentification) technology applied to the invention of Korea Patent Publication No. 2005-15531 is a non-contact recognition technology that transmits and processes information of objects and surrounding environment information by radio frequency by attaching a small chip to various articles. This is also known as Dedicated Short Range Communication (DSRC) or wireless identification technology.

The system applied with RFID technology consists of an RFID reader with a read / decode function, an RFID tag with unique information, operation software, and a network. RFID readers process information by identifying thin, flat RFID tags attached to objects.

RFID tags consist of a semiconductor-made transponder chip and an antenna, which are passive and active. While passives operate by receiving energy from the radio signal of the reader without the need for an internal power source, active RFID has a built-in RFID tag power source for its own operation. It is also classified into a chip tag using a silicon semiconductor chip and a chipless tag composed only of an LC device, a plastic or a polymer device.

RFID technology does not require direct contact or scanning in the visible band as a bar code. Because of these advantages, it is evaluated as a technology to replace the bar code, and the range of application is expanding. Low-frequency RFID systems (30 kHz to 500 kHz) are used at short distances of less than 1.8 m, while high-frequency RFID systems (850 MHz to 950 MHz or 2.4 GHz to 2.5 GHz) can transmit over a distance of 27 meters.

6 is a flowchart illustrating a call origination method of a mobile communication terminal using RFID according to the present invention.

The configuration of the present invention shown in FIG. 2 together with the flowchart of FIG. 6 will be described.

First, it is determined whether a search expression is used (S601), and if a search expression is used, a search expression is input (S602). If the search expression is not used, the process proceeds to step S603 to be described later.

The user can select whether to use the search type before contacting the RFID tag 221 to the mobile communication terminal 210. Whether to use the search expression is displayed to the user through the display unit 214 and the user responds through the user interface 215.

The use of the search type may be set by the user before contacting the RFID tag 221 or may be implemented so that the mobile communication terminal 210 asks the user when the RFID tag 221 is in contact. When the RFID tag 221 is contacted, the user may be asked whether to use the search expression. If the user is asked to use the search expression only when there are two or more RFID tags 221 contacting the mobile communication terminal 210. You see it. This is because there is no need to use a search expression if there is only one RFID tag 221. The search expression is input by the user through the user interface 215.

After the step of inputting the search expression using the search expression or the step of not inputting the search expression because the search expression is not used, the mobile communication terminal 210 contacts the business card or product 220 having the RFID tag 221 embedded therein. (S603). In FIG. 6, only a case in which the RFID tag 221 is touched after the search expression is input is illustrated in the flowchart. However, as described above, the user may be asked whether the search expression is used while contacting the RFID tag 221.

If there is a contact of the RFID tag 221, it is determined whether the information of the RFID tag 221 is received by the mobile communication terminal 210 (S604). The RFID information is received by the RFID recognition unit 212.

If the tag information is not received as a result of the determination in step S604, the user displays a message indicating that the information failed to be received and asks whether to attempt to receive it again (S605). This message is displayed to the user through the display unit 214.

If the user instructs to receive again, the process returns to step S604 to determine again whether the tag information has been received. If the user tells the user not to listen again, the process ends. Commands are made via user interface 215.

When tag information is received in step S604, the tag information is stored in a memory of the mobile communication terminal (S606). Thereafter, the RFID recognition unit 212 of the mobile communication terminal 210 determines whether there is more recognizable tag information (S607). If there is more recognizable tag information, the process returns to step S604 to receive tag information (S604). This is stored in the memory (S606).

If there is no further tag information as a result of the determination in step S607, it is determined whether a search expression is used (S608). Use of the search expression is selected by the user in step S601.

If the search result of the determination in step S608 is used, tag information corresponding to the search expression is selected from the tag information stored in the memory (S609).

After that, it is determined whether there are two or more telephone numbers (S610), and if there is only one telephone number, the process goes to step S613 and sends a call to the telephone number. If there are two or more telephone numbers, the telephone numbers are displayed on the display unit 214 to the user (S611). In this case, the displayed phone numbers are all phone numbers of tag information recognizable if the search expression is not used, but the phone numbers selected by the search expression if the search expression is used.

When the user selects one of the telephone numbers through the user interface 215 (S612), the call is sent to the telephone number (S613).

When a call is made, the call is made using the mobile communication terminal 210 (S614) and ends.

The present invention has been described above.

The invention is not limited to business cards but can be applied to all goods in the same way. Phone number information can be put in a product, and a call can be made by the contact of a portable terminal.

For example, when the product is broken by storing phone number information of the A / S center of the product in the RFID tag embedded in the product, and contacting the RFID tag with a mobile communication terminal capable of recognizing the RFID. You can call the center directly.
