2 is a simple configuration diagram of the RF reader 140 included in the mobile phone 100 according to the present invention.

This figure is a preferred embodiment for each component constituting the RF reader 140 included in the mobile phone 100 in order for the mobile phone 100 to work with the RF tag and / or RF card, in the present invention According to an exemplary embodiment, the RF reader 140 includes an RF controller (eg, a first controller) 145, an RF transmitter 205, an RF receiver 210, and an RF interface 200.

The RF control unit 145 (eg, the first control unit) included in the RF reader 140 does not depend on the control unit 105 (eg, the second control unit or the terminal control unit) of the mobile phone 140 and independently of the RF reader. The control unit 140 controls, and reads or writes information of the RF card and / or the RF tag through the serial interface with the control unit 105 of the mobile phone 100. For example, the RF controller 145 (eg, the first controller) may be a program code memory for controlling the RF interface 200, and may include 64 Kbytes of flash memory and 1 KB of SRAM.

The RF controller 145 (eg, the first controller) transfers the result processed by the RF reader to the controller 105 of the mobile phone 100 through the serial interface.

The RF transmitter 205 of the RF reader 140 is in close proximity of an RF tag and / or RF card (eg, an RF tag and / or RF card that does not have a separate power supply) present within a radio frequency (RF) operating range. It supplies sufficient power to the antenna through the predetermined interface 215 to drive the signal, and transmits a signal (eg, a clock signal, etc.) synchronized with the RF reader 140 to an RF card and / or an RF tag. For example, the RF module 200 transmits a modulated or demodulated frequency to the RF card and / or the RF tag through the RF interface 200 described below.

The RF receiving unit 210 of the RF reader 140 receives and filters predetermined data (frequency) that is answered from an external RF card and / or RF tag, so that the following RF interface 200 processes the corresponding data. Help transfer to a control unit 145 (eg, RF control unit or first control unit) in RF Reader 140.

The RF interface 200 processes frequency modulation and demodulation for data transmission and reception with an external RF card and / or RF tag. According to the present invention, the RF interface 200 encodes the data transmitted from the control unit 145 (eg, the RF control unit or the first control unit) to a designated carrier (eg, 125Khz or 16.58Mhz, etc.), and various modulation schemes. It is responsible for loading the data on the carrier according to.

For example, by reducing the reflection due to the mutual impedance difference generated when connecting the RF reader 140 and the external RF card and / or RF tag of the mobile phone 100, the external and the RF reader 140 of the mobile phone 100 It corrects the impedance difference between the RF card and / or the 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 in the mobile phone 100 is transmitted to the control unit 105 (the second control unit) of the mobile phone 100 through a key input unit (or a voice processing unit) of the mobile phone 100 (300), The control unit 105 of the mobile phone 100 is a control unit (first control unit) 145 of the RF reader 140 via a serial interface for a predetermined command for activating the RF reader 140 provided in the mobile phone 100. ), The control unit 145 of the RF reader 140 initializes the RF reader 140 (305).

When the RF reader 140 is initialized, the RF controller 145 transmits an RF field forming command for detecting and activating at least one RF card in proximity to the RF interface 200 (310). The RF interface 200 forms a radio field for communicating with the RF card and / or the RF tag via the RF transmitter 205. For example, a wireless field coupled with the RF card may be modulated for communication between the RF reader 1400 and the RF card, and may also serve as an energy source for supplying predetermined power to the RF card.

If at least one RF card (or RF tag) approaches the RF reader 140 activated through the process (315), the RF card is a radio frequency (RF) operating range of the RF reader 140. Activation is initiated within the Operating Field (320).

 For example, the frequency fc of the radio frequency operating range is preferably 13.56 MHz ± 7 KHz, and the RF reader displays a field that does not exceed the minimum Hmin value and the maximum Hmax at a position defined by the manufacturer (operating range, operating volume). It is obvious that it should also be possible to power the RF card at the specified location.

Preferably, the RF reader 140 may alternately operate a modulation scheme to detect a type (eg, Type A or Type B) of an approaching RF card.

When activation of the approached RF card is initiated within a radio frequency operating range of the RF reader 140, the control unit 145 of the RF reader 140 may request a predetermined request to search for activation of the adjacent RF card. (Request Commands) and transmits (325), the RF Reader 140 checks whether a predetermined response (Answer To Request) is received from at least one RF card (or RF tag) through the RF receiver 210 ( 330).

If there is a response from two or more RF cards (or RF tags) (335), the RF Reader 140 preferably performs collision avoidance processing for a plurality of RF cards (340).

For example, the control unit 145 of the RF reader 140 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). The SEL and NVB to which the value is assigned are transmitted to the wireless field through the RF transmitter 205 of the RF reader, so that at least one RF card in the wireless field of the RF reader 140 of the mobile phone 100 is Responding to the complete UID CLn 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 the RF card respond. (Repeat until no collision occurs, eg up to 32 times)

On the other hand, if there is a response from one RF card or if one RF card is selected through an anti-collision loop (345), the RF reader controller 145 is a wireless field formed with the RF card through the RF transmitter 205. A SELECT command is transmitted to the RF card via an RF field (350), and mutual authentication between the RF reader and the RF card is performed to prepare a basis for data communication with the RF card (355).

When the authentication operation between the RF reader 140 and the RF card is completed, the RF reader 140 receives predetermined data from the RF card and / or data on the RF card through an RF field. Recording (360), the RF control unit 145 of the RF reader 140 also transmits the data processing history to the mobile phone control unit 105 through a serial interface, the mobile phone control unit 105 performs a number of functions The processing details are expressed in connection with a unit (eg, a screen output unit, an audio output unit, etc.) (365). (E.g., display, etc.)

When the series of operations between the RF reader 140 and the RF card is completed as described above, the RF reader 140 transfers a predetermined command for deactivating the RF card, thereby converting the RF card to the HALT state ( 370).

4 is a simple configuration diagram of an RF reader 140 according to another embodiment of the present invention.

FIG. 1 illustrates that the RF reader 140 is located outside the mobile phone 100, and is detachable through a predetermined slot (eg, a slot capable of serial interface communication) of the mobile phone 100, for example, a mobile phone. (100) If the inside is unable to mount the RF Reader 140 module due to problems such as narrow space, the mobile phone 100 is to be equipped with a detachable RF Reader 140 through an external slot.

According to the present invention, the mobile phone is provided with an RF reader interworking with at least one RF card and / or RF tag and communicating with the mobile phone control unit (eg, the central processing unit, etc.) via a serial interface, whereby the mobile phone control unit is provided with the RF. Since only the information processing result is received from the RF reader without separate control of the reader, there is an advantage that the RF reader can be applied to the mobile phone without significant modification of the software in the existing mobile phone.
