Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 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 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 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 141 can be configured to detect the proximity of the object with a change of 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 with no object touching the touch screen 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 141 can detect 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. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses 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, Detection.

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 then transmits the corresponding data to the control unit 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on 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 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 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 121 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 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.

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 CDMA wireless communication system includes at least one terminal 100, at least one base station (BS) (also referred to as a Node B or Evolved Node B), at least one Base Station Controllers (BSCs) , And a Mobile Switching Center (MSC). The MSC is configured to be coupled to a Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be paired with the BS via a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs may be included in a CDMA wireless communication system.

Each of the plurality of BSs may comprise at least one sector, and each sector may comprise an omnidirectional antenna or an antenna pointing to a particular direction of radial emission from the BS. In addition, each sector may include two or more antennas of various types. Each BS may be configured to support a plurality of frequency assignments, and a plurality of frequency assignments may each have a specific spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. The BS may be referred to as a base station transceiver subsystem (BTSs). In this case, a combination of one BSC and at least one BS may be referred to as a "base station ". The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS may be referred to as a plurality of cell sites.

A broadcast transmission unit (BT) transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 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 100. The satellite aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 100 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 transmissions.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 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 115 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 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit the location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi position location server through the mobile terminal 100, 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 mobile terminal 100 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 100 and extract the 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.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 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 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, 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 terminal based on the collected 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 100 is transmitted to the mobile terminal 100 via the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 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 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

Next, a Bluetooth connection method according to an embodiment of the present invention will be described with reference to FIG. 2 to FIG.

2 is a ladder diagram illustrating a Bluetooth connection process between a first mobile terminal 100 and a second mobile terminal 100 according to an embodiment of the present invention.

First, the controller 180 of the second mobile terminal 100 scans peripheral devices that can be connected by Bluetooth (S101).

The control unit 180 of the second mobile terminal 100 can search for other devices that are turned on in the vicinity of the Bluetooth through the scanning.

The display unit 151 of the second mobile terminal 100 may output a list of the devices searched through the scanning. The devices are devices that can be connected with Bluetooth in the vicinity, so as to inform the user of certain devices, and to receive an input of a device to be connected to a device retrieved from the list.

The control unit 180 of the second mobile terminal 100 receives a device selection input for selecting one of the devices from the list output through the display unit 151 (S103).

The user can select a device to which the Bluetooth connection is to be made from among the list output by the display unit 151 of the second mobile terminal 100. [

The control unit 180 of the second mobile terminal 100 transmits the second Bluetooth MAC address of the second mobile terminal 100 to the selected first mobile terminal 100 in step S105.

And informs the selected first mobile terminal 100 of its MAC address for Bluetooth connection to attempt Bluetooth connection for both terminals.

Although the mobile terminal 100 has been described as an example of a selected device, the mobile terminal 100 may be a headset, a tablet, a watch, or the like.

Also, the second mobile terminal 100 receives the Bluetooth MAC address of the first mobile terminal 100 from the first mobile terminal 100 (S107).

The first mobile terminal 100 and the second mobile terminal 100 receive the corresponding Bluetooth MAC address and establish a Bluetooth connection with the device corresponding to the received Bluetooth MAC address through link key generation.

The controller 180 of the second mobile terminal 100 generates a link key shared with the first mobile terminal 100 corresponding to the received Bluetooth MAC address for Bluetooth connection in step S109.

The link key is a key that is shared only by connected devices for security between Bluetooth connected devices.

It is possible to prevent other devices that do not know the link key from interfering.

The second Bluetooth MAC address of the second mobile terminal 100 received by the BT module of the first mobile terminal 100 is referred to as the Main of the first mobile terminal 100 and the second Bluetooth MAC address of the second mobile terminal 100, And a link key can be generated through the operation.

Next, a link key generation method will be described with reference to FIG. 3 to FIG.

In the present invention, two methods are described as an example of a link key generation method, but the present invention is not limited thereto.

3 is a diagram illustrating a first method for generating a link key.

For example, Device 1 and Device 2 want to make a Bluetooth connection.

Each device that wishes to connect via Bluetooth can receive the same PIN that the user enters.

Also, it is possible to share the random number IN_RAND generated by the random number generator of Device 1, which is a pairing device.

A random number is a set of numbers that are arranged in such a way as to collect samples without any bias, with a certain probability when collecting several samples in disorderly scattered sets. When a random number is sampled, the result obtained from the sample corresponds to the result obtained by examining the entire population to which the sample belongs.

The control unit 180 generates an initialization key (KINIT) using the random number IN_RAND shared with the input PIN.

Encrypts (LK_RAND1,2, KINIT) the random numbers (LK_RAND1,2) generated in each device by using the generated initialization key (KINIT) and transmits it to the counterpart device.

The transmitted keys COMB_KEY1 and COMB_KEY2 are used to generate the secret key of the other party, and the link key KLINK is generated using the generated secret key and the secret key of the user.

When the link key generation is completed, mutual authentication proceeds. Since the generated link key is shared only between the two mobile terminals 100, the partner device can be authenticated using the link key.

The above-described method is a method used when a link key is generated mainly between devices that do not have the display unit 151. [

Next, a second method of generating a link key will be described with reference to FIG.

The method shown in FIG. 4 may be a method of generating a link key used mainly between devices having a display unit 151.

This may be a more secure method than the first method described above. This is because the method described earlier for security enhancements further includes Numeric Comparison authentication.

Each mobile terminal 100 generates its own public keys PK1,2 and private key SK1,2 and transmits the public keys PK1,2 to the partner device for Bluetooth connection.

And generates a Diffie Hellman key KDH using the received relative public keys PK1 and PK2 and its own private keys SK1 and SK2.

Specifically, the device 1 uses its own secret key SK1 and the relative public key PK2, and the device 2 uses the secret key SK2 and the relative public key PK1 to transmit the Diffie Hellman key KDH, .

The Diffie Hellman key is often used as a key exchange method to securely transmit a key rather than being used as a cipher itself.

In addition, two authentication steps may be required in this method.

The first authentication step (Authentication Stage 1) outputs a minimum 6-digit number output through the calculation process using the public key PK1,2 and the random number N1,2 of the self and the pairing partner, It is a confirmed procedure.

The matching check process is performed through a screen as shown in FIG. 8, and a detailed description will be given later.

When the control unit 180 receives an input indicating that the numbers match, the control unit 180 determines that the partner device to be connected by Bluetooth is correct and proceeds to the second authentication step.

In the second authentication step (Authentication Stage 2), the E1 value is generated using the value (N2, BD_ADDR2) previously received by the pairing attempt device and the value (KDH, N1, BD_ADDR1) And sends the verification request to the counterpart device.

The counterpart device verifies the value E1 using the same algorithm, and when the values match, it generates its own value E2 in the same way and requests verification from the pairing device.

In this way, the link key (KLINK) is generated when the second authentication step is completed.

When the link key generation is completed through the above process, mutual authentication proceeds. Since the generated link key is shared only between the two mobile terminals 100, the partner device can be authenticated using the link key.

Fig. 2 will be described again.

The controller 180 of the second mobile terminal 100 authenticates the first mobile terminal 100 via the generated link key and completes the Bluetooth connection (S111) .

When the Bluetooth connection is completed, each mobile terminal 100 can transmit and receive various data without using a cable connection using the frequency band of 2.4 GHz.

Next, an NFC connection method according to an embodiment of the present invention will be described with reference to FIG.

5 is a ladder diagram showing an NFC connection process.

NFC is a wireless communication method that does not require a separate communication authentication process such as Bluetooth or WiFi.

First, the controller 180 of the second mobile terminal 100 activates the NFC connection (S201).

The NFC scheme can consist of a reader that reads tags and tags.

NFC connection activation may refer to a state in which the second mobile terminal 100 becomes a leader and a second mobile terminal 100 is waiting for another tag device to be tagged.

Next, the controller 180 of the second mobile terminal 100 may sense the tag of the first mobile terminal 100 for NFC connection in the NFC connection activation state (S203).

The NFC uses a frequency band of 13.56 MHz and can exchange data within a distance of about 10 cm. Therefore, tag input is required.

The tag may be an operation for bringing the first mobile terminal 100 and the second mobile terminal 100 that want to exchange data close to each other.

Upon sensing the tag operation, the controller 180 of the second mobile terminal 100 transmits data to the first mobile terminal 100 (S205).

Also, the second mobile terminal 100 may receive data transmitted by the first mobile terminal 100.

The transmitted data may include, for example, photographs, moving pictures, documents, contact information, etc. stored in the mobile terminal 100.

NFC can be defined as three operation modes: P2P mode, Reader / Writer mode, and Card Emulation mode.

P2P mode is a mode in which two NFC compatible devices operate as card readers and can transmit data to each other.

The Reader / Writer mode is a mode in which the terminal recognizes the RFID tag information in the NFC activated state and the terminal operates as a card reader. The NFC terminal is contacted to the poster with the RFID tag to acquire direct information and provide connection to the related website.

Card Emulation mode is a mode that can always be recognized by the reader regardless of whether the terminal is ON or OFF. It combines contactless smart card technology and security technology to provide secure mobile payment method.

The first mobile terminal 100 may store the data received through the NFC in the memory 170. [

The second mobile terminal 100 receives the response data transmitted from the first mobile terminal 100 indicating that all the data have been received (S207).

When the first mobile terminal 100 receives all the data, it may transmit the response data indicating that the mobile terminal 100 has received the data to the second mobile terminal 100.

As the second mobile terminal 100 receives the response data, the NFC connection between the first mobile terminal 100 and the second mobile terminal ends.

The Bluetooth connection and the NFC connection are made by different processes as shown in FIGS. 2 and 5, respectively.

According to another embodiment of the present invention, both the Bluetooth connection and the NFC connection can be performed in one process.

Next, with reference to FIG. 6, a method of performing Bluetooth connection and data transmission through NFC together will be described.

6 is a ladder diagram showing a process of performing Bluetooth connection and data transmission through NFC at one time.

In the case where there are the same steps as those described above, the details are the same as those described above, and therefore will be omitted.

The controller 180 of the second mobile terminal 100 activates the NFC connection (S301).

The details are the same as those described in step S201.

The controller 180 of the second mobile terminal 100 detects the NFC tag of the first mobile terminal 100 in the NFC connection activation state (S303).

NFC tag, this is to explain that the tag operation for NFC connection and Bluetooth connection is the same operation as NFC tag operation, and is not limited to the name of NFC tag.

As the first mobile terminal 100 and the second mobile terminal 100 are tagged, each device can be connected and transmitted by NFC method.

The details are the same as those described in step S203.

The local area communication module 114 of the second mobile terminal 100 transmits data to the first mobile terminal 100 using the NFC scheme (S305).

For example, the payment information stored in the memory 170 of the second mobile terminal 100 may be transmitted to the first mobile terminal 100.

The first mobile terminal 100 transmits the payment information used when the payment is made to the second mobile terminal 100 to the first mobile terminal 100, So that the service can be used. At this time, the first mobile terminal 100 may be a wearable device, but this is merely an example.

The details are the same as those described in step S205.

The short range communication module 114 of the second mobile terminal 100 transmits the Bluetooth MAC address of the mobile terminal 100 using the NFC (S307).

If the first mobile terminal 100 and the second mobile terminal 100 are tagged, the bluetooth MAC address and other data may be transmitted. In order to illustrate, the steps are shown separately. Therefore, step S307 is included in step S305, and the order of each step may be changed.

Also, the method differs from the method shown in FIG. 2 in that the second Bluetooth MAC address transmission of the second mobile terminal 100 is transmitted through the NFC + SE, not the BT module.

According to one embodiment of the present invention, when the Bluetooth connection is performed only, the Bluetooth MAC address of the second mobile terminal 100 is transmitted through the BT module, but the Bluetooth connection and the NFC connection are simultaneously performed. The second Bluetooth MAC address of the second mobile terminal 100 is transmitted.

The concrete contents are the same as those described in step S105.

The short range communication module 114 of the second mobile terminal 100 receives the Bluetooth MAC address of the first mobile terminal 100 from the first mobile terminal 100 using the NFC (S309).

Similarly, unlike the method shown in FIG. 2, the first mobile terminal 100 receives the first Bluetooth MAC address through the NFC + SE instead of the BT module of the first mobile terminal 100. This is to perform NFC connection and Bluetooth connection with one tag operation.

The Bluetooth MAC address of the first mobile terminal 100 may be stored in the memory 170 of the first mobile terminal 100 by default. Alternatively, the controller 180 may generate the Bluetooth MAC address and store the Bluetooth MAC address in the memory 170 when the first mobile terminal 100 is reset.

The details are the same as those described in step S107.

The controller 180 of the second mobile terminal 100 generates a link key shared with the first mobile terminal 100 corresponding to the received Bluetooth MAC address at step S311.

The link key generation process may include a procedure for checking whether or not the numbers displayed on the display unit 151 of the first mobile terminal 100 and the numbers displayed on the display unit 151 of the second mobile terminal 100 match.

Also, the operation for generating the link key can be performed by calling the second Bluetooth MAC address received through the NFC + SE from the second mobile terminal 100 as the Main of the first mobile terminal 100.

In FIG. 2, the second Bluetooth MAC address, which is referred to as the Main of the first mobile terminal 100, is different in that it is received through the BT module instead of the NFC + SE.

The link key generation method is the same as that described in step S109.

As the link key is generated, the Bluetooth connection between the first mobile terminal 100 and the second mobile terminal 100 is completed (S313).

As the Bluetooth connection is completed, data can be transmitted and received between at least one of the terminals until the Bluetooth connection is turned off.

Also, the short-range communication module 114 of the second mobile terminal 100 receives the response data transmitted from the first mobile terminal 100 to the first mobile terminal 100 that received the data (S315).

Upon receiving the response data, the NFC connection between the first mobile terminal 100 and the second mobile terminal 100 is terminated. The NFC connection is terminated, but the Bluetooth connection can be maintained.

The details are the same as those described in step S207.

Next, referring to FIGS. 7 to 13, how the steps described in the above ladder diagrams are outputted on the display unit 151 will be described again with reference to drawings.

7 to 9 are views showing screens output by the display unit 151 of the second mobile terminal 100 when the second mobile terminal 100 requests the first mobile terminal 100 to establish a Bluetooth connection.

7 is a diagram for explaining a scanning process in which the control unit 180 of the second mobile terminal 100 searches for nearby Bluetooth-capable devices for Bluetooth connection.

For example, the control unit 180 of the second mobile terminal 100 can search for Device 1, Device 2, and Device 3 as devices capable of Bluetooth connection in the vicinity. The scanning screen may include at least one of a name 701 of the searched device, a Bluetooth MAC address 702 of the device, and a depth sensitivity 703 of the device.

The name 701 of the device may be a name arbitrarily set by a user of the device or a name set to a default.

The control unit 180 of the second mobile terminal 100 may receive an input for selecting one of the devices Device 1 to Device 3 output by the display unit 151.

When receiving an input for selecting Device 1, there may be a procedure for confirming whether the device to which the user wishes to establish a Bluetooth connection is compatible with the second mobile terminal 100 and Device 1, or both devices.

To this end, the display unit 151 of the second mobile terminal 100 and the display unit of the device 1 may output a screen as shown in FIG.

This process of verifying that the printed numbers match is called the Numeric Comparison Authentication.

The controller 180 of the second mobile terminal 100 may receive an input for checking whether or not the numbers outputted to the display unit 151 of the respective devices to be connected match.

The controller 180 of the second mobile terminal 100 and the device 1 perform the Bluetooth connection when receiving the input 801 indicating that the numbers match.

When the input 802 indicates that the output numbers do not match, the mobile terminal 100 and the device 1 terminate the Bluetooth connection attempt.

Such an identification procedure may be omitted.

This confirmation procedure is mainly required for enhancing security between devices having the display unit 151.

8, when a Bluetooth connection is established between the controller 180 of the second mobile terminal 100 and the device 1, the display 801 of the second mobile terminal 100 151 may output a screen as shown in FIG.

The user can know that the Bluetooth connection is completed through the screen as shown in FIG.

Next, a screen displayed by the display unit 151 of the second mobile terminal 100 when an NFC connection is established between the mobile terminal 100 of the second mobile terminal 100 and another apparatus will be described with reference to FIGS. 10 to 11 .

10 may be a screen showing a state of waiting for the tag input of the controller 180 of the second mobile terminal 100 for the NFC connection.

The user can read an instruction to tag another device on the screen as shown in FIG.

11 is a diagram showing that the NFC connection is completed as another device is tagged to the second mobile terminal 100. [

Since the NFC connection does not require a separate registration procedure, the display unit 151 of the second mobile terminal 100 can output a screen indicating that the connection is completed without a number confirmation screen as shown in FIG.

Next, FIGS. 12 to 13 are views showing a screen for outputting a process of concurrently performing a Bluetooth connection and an NFC connection according to an embodiment of the present invention.

First, the controller 180 of the second mobile terminal 100 can enter a state of waiting for a tag of another apparatus by receiving an input requesting a Bluetooth connection and an NFC connection. Accordingly, the display unit 151 of the second mobile terminal 100 can output a screen as shown in FIG.

13, which indicates that the NFC connection and the Bluetooth connection between the second mobile terminal 100 and another device are completed, the controller 180 of the second mobile terminal 100 detects the tag of another device Can be output.

Since the Bluetooth MAC address is transmitted and received to the partner device through the NFC connection, the authentication procedure as shown in FIG. 8 is unnecessary. This is because the NFC method transmits the Bluetooth MAC address almost exactly to the partner device to be paired, thereby reducing the risk of erroneous transmission to other devices.

Accordingly, there is an effect that data transmission through the Bluetooth connection and the NFC method is performed in a single tag operation.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
