FIG. 3 is a view illustrating a preferred embodiment of each component of the RF reader 145 included in the cellular phone 100 in order for the cellular phone 100 to interwork with an RF tag. According to the present invention, the RF reader 145 includes an RF transmitter 205, an RF receiver 210, and an RF interface 200.

The RF transmitter 205 of the RF reader 145 is in close proximity to the antenna via a predetermined interface to drive RF tags (eg, RF tags without a separate power supply) that exist within a radio frequency (RF) operating range. And modulates or demodulates the RF tag through the RF reader interface 200, for example, by transmitting a signal (for example, a clock signal, etc.) synchronized with the RF reader 145 to an RF tag. Send a signal (frequency) to the RF tag.

The RF receiver 210 of the RF reader 145 receives and filters predetermined data (frequency) that is answered from an external RF tag, and the following RF interface 200 processes the corresponding data and transmits the data to the controller 110. Help

The RF interface 200 processes frequency modulation and demodulation for data transmission and reception with an external RF tag.

3 is a simple flowchart according to a preferred embodiment of the present invention.

When the command to start activation of the RF reader function in the mobile phone 100 is transmitted to the control unit 110 through a key input unit (or a voice processing unit, etc.) of the mobile phone 100 (300), the control unit 110 is connected to the mobile phone 100. The RF Reader function is initialized to activate the RF Reader function (305).

When the RF reader function in the mobile phone 100 is initialized, the controller 110 transmits an RF field formation command for detecting and activating at least one RF tag in proximity to the RF interface 200 (310). The RF interface 200 forms a radio field for communicating with the RF tag through the RF transmitter 205. For example, the wireless field combined with the RF tag may be modulated for communication between the mobile phone 100 and the RF tag, and may also serve as an energy source for supplying predetermined power to the RF tag.

If, through the above process, the RF reader function is activated to the mobile phone 100, at least one RF tag is approached (315), the RF tag is the RF reader radio frequency (RF) operating range of the mobile phone 100 ( Operating field).

 For example, the frequency fc of the radio frequency operating range is preferably 13.56 MHz ± 7 KHz, and the RF reader does not exceed the minimum Hmin value and the maximum Hmax at a position defined by the manufacturer (operating range, operating volume). It is clear that the RF tag should be capable of powering the RF tag at a defined location.

Preferably, the mobile phone 100 may alternately operate a modulation scheme to detect a type (eg, Type A or Type B) of an approaching RF tag.

When activation of the approached RF tag is initiated within an RF reader radio frequency (RF) operating field of the cellular phone 100, the controller 110 of the cellular phone 100 activates the activation of the adjacent RF tag. To send a predetermined request command (Request) to search (325), the control unit 110 of the mobile phone 100 through the RF receiver 210 of the RF Reader 145 in the mobile phone 100, at least In operation 330, a predetermined response (Answer To Request) is received from one or more RF tags.

If there is a response from two or more RF tags (335), the RF Reader 145 of the mobile phone 100 preferably performs anti-collision processing for a plurality of RF tags (340) (eg, ISO / IEC). Anti-collision treatment based on 14443-3).

For example, the anti-collision process is preferably executed in the control unit 110 of the mobile phone 100, the control unit 110 of the mobile phone 100 performs the anti-collision process by applying a collision prevention loop.

For example, the controller 110 of the mobile phone 100 assigns a code for the selected collision avoidance type and a cascade level (CLn) to a Select Command (SEL), and assigns '20' to the Number of Valid Bits (NVB). In addition, the SEL and the NVB to which the value is assigned are transmitted to the wireless field through the RF transmitter 205 of the RF reader 145, so that at least one RF in the wireless field of the RF reader 145 of the mobile phone 100 is transmitted. By having the tag respond to the complete UID CLn, it confirms the collision based on the value of the responded UID CLn, reassigns the valid bit value of the UID CLn received before the collision to the NVB, and retransmits it This can be done by having only RF tags with a response respond. (Repeat until no collision occurs, eg up to 32 times)

On the other hand, if there is a response from one RF tag or if one RF tag is selected through an anti-collision loop (345), the control unit 110 of the mobile phone 100 is the RF transmitter 205 of the RF Reader (145) By transmitting a SELECT command to the RF tag via the RF tag and the RF field formed through the RF tag (350) and performing mutual authentication between the mobile phone 100 and the RF tag (355), the RF tag Provide a basis for data communication with the

When the authentication work between the mobile phone 100 and the RF tag is completed, the mobile phone 100 receives predetermined data from the RF tag and / or writes data to the RF tag through an RF field. (360).

When the series of operations between the mobile phone 100 and the RF tag is completed as described above, the mobile phone 100 transfers a predetermined command for deactivating the RF tag, thereby converting the RF tag to the HALT state (365). .

According to the present invention, the cellular phone has an RF reader function that communicates with a control unit (e.g., a central processing unit) and a predetermined bus (BUS), and interoperates with at least one external RF tag, thereby providing complex hardware in the existing cellular phone. There is an advantage that you can directly control the RF Reader function without adding.

In addition, there is an advantage that it is advantageous to secure an arrangement space for the RF Reader function in a narrow space in the mobile phone.
