[ A plurality of cameras 321 provided in the mobile terminal 300 may be arranged to have a matrix structure and various angles or foci may be provided to the mobile terminal 300 through the camera 321 having a matrix structure A plurality of pieces of image information can be input. In addition, the plurality of cameras 321 may be arranged in a stereo structure to acquire a left image and a right image for realizing a stereoscopic image.

The microphone 322 processes the external acoustic signal into electrical voice data. The processed voice data can be utilized variously according to a function (or a running application program) being executed in the mobile terminal 300. Meanwhile, various noise elimination algorithms may be implemented in the microphone 322 to remove noise generated in receiving an external sound signal.

The user input unit 323 is used to receive information from the user. When information is inputted through the user input unit 323, the control unit 380 can control the operation of the mobile terminal 300 to correspond to the input information . The user input unit 323 may include a mechanical input unit (or a mechanical key such as a button located on the front or rear or side of the mobile terminal 100, a dome switch, a jog wheel, Switches, etc.) and touch-based input means. For example, the touch-type input means may comprise a virtual key, a soft key or a visual key displayed on the touch screen through software processing, And a touch key disposed on the touch panel. Meanwhile, the virtual key or the visual key can be displayed on a touch screen having various forms, for example, a graphic, a text, an icon, a video, As shown in FIG.

Meanwhile, the sensing unit 340 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a corresponding sensing signal. The control unit 380 may control the driving or operation of the mobile terminal 300 or may perform data processing, function or operation related to the application program installed in the mobile terminal 300 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 340 will be described in more detail.

First, the proximity sensor 341 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 341 may be disposed in the inner area of the mobile terminal or the proximity sensor 341 near the touch screen.

Examples of the proximity sensor 341 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 341 can be configured to detect the proximity of the object with a change in the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity to the touch screen without touching the object is referred to as "proximity touch" The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 341 is capable of sensing a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. The control unit 380 processes the data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 341 as described above, and further stores the visual information corresponding to the processed data It can be output on the touch screen. Further, the control unit 380 can control the mobile terminal 300 such that different operations or data (or information) are processed depending on whether the touch to the same point on the touch screen is a proximity touch or a contact touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 380 can know which area of the display unit 351 is touched or the like. Here, the touch controller may be a separate component from the control unit 380, and may be the control unit 380 itself.

Meanwhile, the control unit 380 can perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided in the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 300 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. On the other hand, the control unit 380 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 321 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 321 and the laser sensor may be combined with each other to sense the touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 351 displays (outputs) information to be processed by the mobile terminal 300. For example, the display unit 351 can display UI (User Interface) and GUI (Graphic User Interface) information according to execution screen information of an application program driven by the mobile terminal 300 or such execution screen information .

In addition, the display unit 351 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

[ The sound output unit 352 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 353 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 353 may be vibration. The intensity and pattern of the vibration generated in the haptic module 353 can be controlled by the user's selection or setting of the control unit 380. For example, the haptic module 353 may combine and output different vibrations or sequentially output the vibrations.

In addition to vibration, the haptic module 353 may be configured to perform various functions such as a pin arrangement vertically moving with respect to the contact skin surface, a spraying force or suction force of air through the injection port or the suction port, a grime on the skin surface, And various tactile effects such as an effect of reproducing a cold sensation using an endothermic or exothermic element can be generated.

The haptic module 353 can transmit the tactile effect through the direct contact, and the tactile effect can be felt by the user through the muscles such as the finger or the arm. The haptic module 353 may include two or more haptic modules according to the configuration of the mobile terminal 300.

Meanwhile, as described above, the control unit 380 controls an operation related to an application program and an overall operation of the mobile terminal 300. [ For example, when the state of the mobile terminal satisfies a set condition, the control unit 380 can execute or release a lock state for restricting input of a user's control command to applications.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Meanwhile, the sensing unit 340 of the mobile terminal 100 according to an embodiment of the present invention may include a tab sensing unit for sensing a tab or a tab gesture that the user hits the main body or the display unit 351 343).

Here, the tap sensing unit 343 may sense a main body of the mobile terminal 300, a display unit 351, or a gesture of tapping an object. More specifically, the tab may be formed by tapping the mobile terminal 300 or the display unit 351 or an object or a tap object with a tap object such as a finger lightly on the body of the mobile terminal 300, the display unit 351, It can be understood as an operation of making contact.

The tap object to which the tab is applied may be a body of the mobile terminal 300 or a display unit 351 or an object capable of exerting an external force on an object. For example, a finger, a stylus pen, a pen, a pointer, a fist, and the like. The tap object is not limited to an object that can input a touch input to the mobile terminal 300 according to the present invention. The tap object may be a touch screen that can apply an external force to the mobile terminal 300, the display unit 351, If it is an object, its kind is irrelevant.

Meanwhile, the object to which the tap gesture is applied may include at least one of the body of the mobile terminal 300, the display unit 351, and the object on which the mobile terminal 300 is placed.

Meanwhile, in the present invention, the tap or tap gesture may be sensed by at least one of the acceleration sensor and the touch sensor included in the tap sensing unit 343. [ Here, the acceleration sensor is a sensor capable of measuring dynamic forces such as acceleration, vibration, and impact of the main body of the mobile terminal 300.

That is, the acceleration sensor senses the motion (or vibration) of the main body of the mobile terminal 300 generated by the tap gesture, and detects whether the tap is applied to the object. Accordingly, the acceleration sensor may detect the taps of the mobile terminal 300 or the display unit 351, or may detect movement or vibration of the mobile terminal 300, It is possible to detect that an object positioned close to the object is tapped.

As long as the acceleration sensor is capable of detecting movement or vibration in the main body of the mobile terminal 300, the acceleration sensor can be used not only when the tab is applied to the main body of the mobile terminal 300 or the display unit 351, It is possible to detect the tab even if it is applied to an off-site.

In the mobile terminal according to the present invention, only one of the acceleration sensor and the touch sensor may be used, or the acceleration sensor and the touch sensor may be sequentially used to detect the taps of the mobile terminal 300 or the display unit 351 , Or an acceleration sensor and a touch sensor can be used at the same time. On the other hand, in order to sense a tap, a mode using only an acceleration sensor may be named as a first mode, a mode using a touch sensor may be referred to as a second mode, and both the acceleration sensor and the touch sensor may be used Mode) may be referred to as a third mode or a hybrid mode.

On the other hand, when the tab is sensed through the touch sensor, it is possible to more accurately grasp the position where the tab is sensed.

In the mobile terminal 300 according to the present invention, in order to sense the tab through the acceleration sensor or the touch sensor, the power supply unit (not shown) may be connected to the sensing unit 340 390 may be maintained in a particular mode of operation in which the minimum current or power applied is maintained. This particular mode of operation may be referred to as a 'doze mode'.

For example, in the doze mode, only a light emitting element for outputting a screen in the display unit 351 is turned off in a touch screen structure in which a touch sensor and a display unit 351 have a mutual layer structure, The sensor may be in the on-state state. Alternatively, the doze mode may be a mode in which the display unit 351 is turned off and the acceleration sensor is kept on. Alternatively, the dose mode may be a mode in which the display unit 351 is turned off, and the touch sensor and the acceleration sensor are all kept on.

Therefore, in the doze mode state, that is, when the display unit 351 is turned off, or when the display unit 351 is turned off (the display unit 351 is inactive) When the tap is applied to at least one point on the mobile terminal 300 or a specific point of the main body of the mobile terminal 300, it is possible to detect that the tap has been applied from the user through at least one of the on- have.

Also, the tap detection unit 343 may determine that a "tab" for controlling the mobile terminal 300 is detected only when at least two or more tabs are applied within the reference time. For example, when one tap is applied to the display unit 351 by a touch object capable of applying a touch to the display unit 351, the tab sensing unit 343 outputs the one tap as a touch input Can be recognized. That is, in this case, the control unit 380 does not control the function corresponding to the one tap, but the function corresponding to the touch input corresponding to the one tap (for example, A function of selecting an icon) can be controlled.

Accordingly, the control unit 380 controls the tap sensing unit 343 to control one or more functions only when at least two or more tabs (or a plurality of times) that are continuously applied within the reference time are detected, Quot; tab " is detected.

That is, tap gestures may mean that at least two or more tap gestures are continuously sensed within a reference time. Accordingly, in the following description, the detection of a "tap " may mean that a user's finger or touch pen is struck on the body of the mobile terminal 300 or the display unit 351 a plurality of times .

Further, the controller 380 may determine whether the tab is sensed by the user's other finger or the user's finger, as well as the tab is sensed within the reference time. For example, when the tabs are sensed in the display unit 351, the controller 380 determines whether the tabs are formed through one finger or through different fingers Can be detected. The control unit 380 recognizes the position of the taps on the display unit 351 or the acceleration generated due to the taps through at least one of the touch sensor and the acceleration sensor included in the tap sensing unit 343, You can detect if the tabs are made with one finger or each with a different finger.

Further, the controller 380 may further determine whether the user has input the tabs through one hand or one finger, or both hands or at least two fingers It is possible to judge whether or not it is inputted.

The taps may be a plurality of tapes continuously sensed within the reference time. Here, the reference time may be a very short time, for example, 300 ms to 2 s or less.

If it is detected that the main body of the mobile terminal 300 has been tapped for the first time, the tap detecting unit 343 detects the first tapping within the reference time from the time when the first tapping is detected, Can be detected. If the next tap is detected within the reference time, the tap detection unit 343 or the control unit 380 detects that a tab for controlling a specific function of the mobile terminal 300 is detected according to the embodiment of the present invention It can be judged. The control unit 380 recognizes the tab as a valid tap only when the second tab is detected within a predetermined time period after the first tab is detected and determines whether the user wants to control the mobile terminal 300, It is possible to distinguish whether a tab is added or not.

There are various methods for allowing the 'valid tap' to be recognized. For example, the control unit 380 may display the main body or the display unit 351 by a second reference number or a second reference number within a predetermined time after a first tap touched by a first reference number or more than a first reference number is detected, It may be recognized that the second tap that is knocked more than the number of times is detected as the 'valid tap'. Here, the number of the first reference times and the number of the second reference times may be equal to or different from each other. For example, the first reference number may be one, and the second reference number may be two. As another example, the first reference number and the second reference number may all be one.

Also, the control unit 380 can determine that the "tabs " have been detected only when the tab is within the" predetermined area ". That is, when it is detected that the main body of the mobile terminal 300 or the display unit 351 is tapped for the first time, the control unit 380 can calculate a predetermined area from the point where the first tapping is detected. Then, the controller 380 determines whether or not the first hit is followed by the first or second reference count, or the first or second reference count is exceeded within the reference time from the time when the first hit is detected, It can be determined that the first tab or the second tab is applied.

It is to be understood that the reference time and the predetermined region may be variously modified according to the embodiment.

Meanwhile, the first tap and the second tap may be sensed not only as a reference time and a predetermined area, but also as separate tabs depending on the detected position of each tab. That is, the controller 380 may determine that the first tab and the second tab are applied when the second tab is detected at a position spaced apart by a predetermined distance from the position where the first tab is sensed. When the first tap and the second tap are recognized based on the sensed position, the first tap and the second tap may be simultaneously detected.

Also, when the first tap and the second tap are configured by a plurality of touches, that is, a plurality of tapes, a plurality of touches constituting the first tap and the second tap may be simultaneously detected. For example, when the first touch constituting the first tab is detected and the first touch constituting the second tab is positioned at a position spaced apart from the position where the first touch of the first tab is sensed If it is sensed, the controller 380 can sense the first touch constituting the first tap and the second tab, respectively. The controller 380 senses an additional touch input sensed at each position and determines that the first tap and the second tab are applied when a touch is detected at a first reference frequency or at a second reference frequency can do.

If the tab of the main body of the mobile terminal 300 is detected a plurality of times from the tab sensing unit 343, the control unit 380 determines at least one of the functions executable in the mobile terminal 300 One can be controlled.

For example, the control unit 380 may control at least one of the functions executable on the mobile terminal when the plurality of tabs meet the predetermined condition. For example, the control unit 380 may control different functions depending on whether the user uses only one finger or one hand, or at least two fingers or both hands when the user applies the plurality of tabs. Or at least one of functions executable in the mobile terminal 300 based on the current operation state of the mobile terminal 300 and the environmental state of the mobile terminal 300 may be controlled based on the plurality of taps.

Here, the functions that can be executed on the mobile terminal 300 may mean all kinds of functions that can be executed or operated on the mobile terminal 300. For example, one of the executable functions may be an application installed in the mobile terminal 300. For example, " an arbitrary function is executed " may mean that " an arbitrary application is executed or driven in the mobile terminal 300 ".

As another example, the functions executable in the mobile terminal 300 may be functions necessary for the basic operation of the mobile terminal 300. [ For example, the functions required for the basic operation may be a function of turning on / off the illumination provided on the display unit 351, or switching the mobile terminal 300 from the released state to the locked state, A function of changing the setting information of the mobile terminal 300, and the like.

Meanwhile, the power supply unit 390 of the mobile terminal according to the embodiment of the present invention includes a pattern recognition unit (not shown) capable of recognizing a pattern of a user formed from the plurality of taps applied to the mobile terminal 300 in the doze mode state 392). In this case, the pattern recognition unit 392 can compare the pattern formed from the plurality of taps and the pre-stored pattern in the doze mode state, and the control unit 380 and / Power can be applied to each component. Accordingly, the mobile terminal 300 according to the embodiment of the present invention can be configured such that the power of the mobile terminal 300 is turned on based on a plurality of taps applied on the main body or the display portion 351, .

In addition, the function of the mobile terminal 300 executable based on the plurality of taps may be a function of turning off the power of the mobile terminal 300. In this case, the control unit 380 can turn off the power of the mobile terminal 300 by the plurality of taps, and conversely, when the mobile terminal 300 is powered off, . Accordingly, the present invention can control power on / off of the mobile terminal 300 without using the power key.

In some cases, electronic components may be mounted on the rear case 302 as well. Electronic parts that can be mounted on the rear case 302 include detachable batteries, an identification module, a memory card, and the like. In this case, a rear cover 303 for covering the mounted electronic component can be detachably coupled to the rear case 302. Therefore, when the rear cover 303 is separated from the rear case 302, the electronic parts mounted on the rear case 302 are exposed to the outside.

As shown, when the rear cover 303 is coupled to the rear case 302, a side portion of the rear case 302 can be exposed.

However, these configurations are not limited to this arrangement. These configurations may be excluded or replaced as needed, or placed on different planes. For example, the first operation unit 323a may not be provided on the front surface of the terminal body, and the second sound output unit 352b may be provided on the side surface of the terminal body rather than the rear surface of the terminal body.

The display unit 351 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

For example, wireless interfaces that can be used by a communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) ), Universal mobile telecommunication systems (UMTS) (in particular Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications May be included.

Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system as well as a CDMA wireless communication system.

A broadcast transmission unit (BT) transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 311 shown in FIG. 4 is provided in the terminal 300 to receive a broadcast signal transmitted by the BT.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 300. The satellite aids in locating the mobile terminal 300. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 300 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 315 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal. Typical examples of the location information module 315 include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 315 may perform any of the other functions of the wireless communication unit 310 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 315 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 315 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 300, a wireless AP connected to the mobile terminal 300, and a database in which certain wireless AP information is stored.

The mobile terminal 300 connected to the wireless AP can transmit the location information request message to the Wi-Fi location server.

The Wi-Fi location server extracts information of the wireless AP connected to the mobile terminal 300 based on the location information request message (or signal) of the mobile terminal 300. The information of the wireless AP connected to the mobile terminal 300 may be transmitted to the Wi-Fi location server through the mobile terminal 300 or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the MS 300 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 300 and extract wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Thereafter, the Wi-Fi position location server may extract (or analyze) the location information of the mobile terminal 300 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 300.

As a method for extracting (or analyzing) the position information of the mobile terminal 300, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile station based on the collected signal strength information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The location information of the extracted mobile terminal 300 is transmitted to the mobile terminal 300 through the Wi-Fi location server, so that the mobile terminal 300 can acquire the location information.

The mobile terminal 300 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 300 may be variously changed according to the wireless communication environment where the mobile terminal 300 is located.

As shown in FIG. 4, the mobile terminal according to the present invention may include Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 300 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. When the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is a general control type, it can execute appropriate operations according to the control contents.

When the NFC module is operated in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. For P2P communication, a connection can be created between the mobile terminal and another mobile terminal. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.
