The specific terms used in the embodiments of the present invention are provided to facilitate understanding of the present invention, and the use of such specific terms may be changed into other forms without departing from the technical idea of the present invention.

One. NFC ( Near Field Communication )

Near Field Communication (NFC) is a short-range wireless connection standard using magnetic field induction between adjacent devices.The relevant standards include Ecma 340, ISO / IEC 18092, ISO / IEC 21481, NFC Data Exchange Format (NDEF), Record Type Definition (RTD), LLCP (Logical Link Control Protocol). This method can be regarded as a kind of RFID (Radio Frequency Identification), and it has a big difference in that it supports two-way communication unlike a smart card which uses a frequency of 13.56 MHz band similar to a smart card but supports unidirectional communication only . In other words, unlike a smart card that only serves as a tag that stores and transmits specific information to a reader, NFC serves as a reader / writer that reads or writes information of a tag as well as a tag as needed. In addition, when NFC is provided in both mobile terminals, it may also be used for P2P (Point to Point) information exchange. This technology can realize high security level compared with bluetooth and has an advantage of providing quick connection. Although the communication distance is shorter (up to 10 ~ 20cm) than Bluetooth type, there is an advantage that confusion is reduced in a complex space. In addition, it is possible to establish a communication immediately even if the mobile terminal is located at a short distance without requiring a separate user recognition, and the communication time is relatively short, which is advantageous for security.

The mobile terminal equipped with the NFC module can be driven in three modes of reader mode, card mode and P2P (peer to peer) mode. A series of processes for sequentially changing these three modes is called polling. At this time, the order in which each mode is changed in the polling operation is not fixed and can be changed. The total time required for each operation of each mode is called a polling period (interval), and the mobile station repeats the polling operation at intervals of the polling period.

Details of each mode included in the NFC function are as follows. Hereinafter, for convenience of description, a case in which the NFC module of the mobile terminal is approached within a predetermined distance so as to be activated is referred to as "NFC touch" for convenience, and the user's operation for the mobile terminal is "tagging". This is called.

First, in the reader mode, the mobile terminal performs a card reader function. That is, the mobile terminal can read the information of the external NFC device by transmitting a predetermined command message to the NFC device, the NFC touch, and receiving a response message in response to the command message.

More specifically, the mobile terminal generates a radio frequency field to read information of the external NFC apparatus. The radio frequency field refers to a radio wave in which the intensity of the magnetic field changes periodically. When the external NFC device makes an NFC touch with the mobile terminal emitting the radio wave, an induced current is generated through the coil provided in the external NFC device due to the radio wave emitted by the mobile terminal. The external NFC device wirelessly transmits information stored in the memory chip or the like to the mobile terminal by using the induced current generated. That is, since the external NFC device transmits information through the radio wave radiated from the mobile terminal, the power source is not required, but the mobile terminal must receive power to emit radio waves.

As an example in which the mobile terminal operates in the reader mode, when the user NFC touches the mobile terminal to the credit card, the user can inquire the expected amount of payment, the limit amount, etc. of the credit card through the screen of the mobile terminal, and the server of the credit card company A URL (Universal Resource Locator) can be obtained and connected to the server of the credit card company. In addition, when the user NFC touch the mobile terminal to the tag attached to the various items, the user can check the detailed information such as the price of the goods, the distribution date through the screen of the mobile terminal.

Second, in the case of the card mode, the mobile terminal performs the function of the tag described above. That is, when the mobile terminal makes an NFC touch with the external NFC reader, the mobile terminal receives the command message of the external NFC reader and transmits a response message in response thereto. In this case, since the induction current is generated in the mobile terminal due to the radio wave radiated by the external NFC reader, the mobile terminal can transmit the response message to the external NFC reader without receiving any power from the inside.

As an example in which the mobile terminal operates in the card mode, when the traffic card chip is mounted in the mobile terminal, the user may NFC the touch terminal to the traffic card reader installed in the bus or the subway to calculate the fare of the bus or the subway. At this time, the traffic card reader transmits a command message requesting the charge information to the mobile terminal, and the mobile terminal transmits the charge information stored in response thereto.

Finally, in the P2P mode, the mobile terminal performs the functions of the NFC reader and the tag together. These are also referred to as an initiator mode and a target mode, respectively. When the mobile terminal touches the NFC with an external NFC device installed with an NFC module, the mobile terminal generates a radio frequency field to read information of the external NFC device or receives the information from the external NFC device through the radio frequency field. The response message according to the command message is delivered. That is, it can transmit or receive predetermined information with the external NFC apparatus. As an example in which the mobile terminal operates in the P2P mode, when the user makes an NFC touch with another mobile terminal by using the mobile terminal, a certain amount of money in the user's account is simply transferred to another user's account or stored in the user's mobile terminal. You can deliver phone books, documents, music, and more.

As described above, in the case of receiving data in the P2P mode, a radio frequency field is not generated, but in the case of transmitting data, it is necessary to generate a radio frequency field. Therefore, a reader mode and a P2P mode, which are modes for generating a radio frequency field, may be referred to as an active mode, and a card mode that does not generate a radio frequency field may be referred to as a passive mode.

2. 1 First NFC  Touch with Tag- NFC application  Verify installation

2 is a diagram illustrating the operation of the mobile terminal when the first NFC touch with the NFC tag according to an embodiment of the present invention.

Referring to FIG. 2, when the mobile terminal 120 makes an NFC touch on the NFC tag 130 by tagging the user (S201), the mobile terminal 120 determines whether the NFC application is installed in the mobile terminal 120. (S203).

In this case, when the display of the mobile terminal 120 is in an off state or in a lock screen state, the mobile terminal 120 may not perform an operation after step S203. Here, the lock screen state is a state in which a general function of the mobile terminal 120 cannot be used until an input for releasing a preset lock state is received from the user. Therefore, when the display is in the lock screen state, the mobile terminal 120 only accepts a limited touch input for releasing it, and does not accept an input for other touch inputs. That is, the operation after step S203 may be performed by the NFC tag 130 and the NFC touch only in a normal screen state or a dimming state. Here, the general screen state refers to a state in which the user can operate a general function of the mobile terminal 120. In this case, the display may be classified into a state of displaying a home-screen image on which the application execution screen is not displayed and a state of displaying an application execution screen. In addition, the dimming state refers to a state in which only the brightness is changed dark while the image displayed on the display is displayed as it is in order to prevent unnecessary consumption of power of the mobile terminal 120 when there is no user input for a predetermined time.

When the NFC application exists in step S203, the mobile terminal 120 executes the NFC application (S205).

On the other hand, if the NFC application does not exist in step S203, the mobile terminal 120 is connected to the service server 110 providing the NFC application transmits a message requesting the NFC application (S207). In this case, the mobile terminal 120 may obtain link information for the service server 110 requesting the NFC application from the NFC tag.

Subsequently, the service server 110 receiving the NFC application request message from the mobile terminal 120 extracts the NFC application among the applications stored therein (S209), and transmits the extracted NFC application to the mobile terminal 120 (S211). .

The mobile terminal 120 receiving the NFC application from the service server 110 installs the received NFC application (S213).

On the other hand, Figure 2 described how to determine the existence of the NFC application, the mobile terminal 120 checks the version of the NFC application, if the version of the NFC application stored in the mobile terminal 120 is not the latest version automatically By connecting to the service server 110 can request and receive the update data for updating to the latest version of the NFC application or the latest version.

2. 2. First time NFC application  Execute-Enter basic setup procedure

3 is a diagram illustrating an operation of a mobile terminal when the first NFC application is executed according to an embodiment of the present invention.

Referring to FIG. 3, when the mobile terminal 120 NFC touches the NFC tag 130 by the tagging of the user, or when the mobile terminal 120 receives an input for executing the NFC application from the user (S301), the mobile terminal 120 determines whether the NFC application is the first execution (S303). In this case, as shown in FIG. 2, when the display of the mobile terminal 120 is in an off state or in a lock screen state, the mobile terminal 120 may not perform an operation after step S303.

If the NFC application is the first execution in step S303, the mobile terminal 120 operates the setting menu in the NFC application and outputs the setting menu through the display of the mobile terminal 120 (S305).

The setting menu may include a mode selection menu, an external device / tag registration menu, and a channel gateway (CH G / W) registration menu.

The mode selection menu refers to a menu for selecting an operation process of a tagging mode in the mobile terminal 120. The tagging mode refers to an operation in which the mobile terminal 120 automatically pairs with the external device 140 when the NFC tag 130 touches the NFC tag 130 to interwork the same application as the mobile terminal 120 and the external device 140. The tagging mode may include a basic mode (automatic execution mode), a selective execution mode, and a launcher mode. The basic mode (autorun mode) refers to a mode for interlocking the same application as the application running on the mobile terminal 120 in the external device 140, and the selective execution mode refers to a mode for interlocking a specific application set by the user. The launcher mode refers to a mode in which the NFC tag 130 and an application to be executed by the user at the time of NFC touch are selected and linked with the selected application. Such a detailed description of the operation of the tagging mode will be described later.

The external device / tag registration menu is set in advance for the external device 140 for interlocking and executing an application executed in the mobile terminal 120. Thus, the external device / tag registration menu moves to start the interlocking operation of the external device 140 and the application.
