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 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.

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 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 camera 121 and the laser sensor may be combined with each other to sense a 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.

[ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different wireless interfaces and / or physical layers. 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 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).

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present invention proposes a function (cell phone) case capable of expanding the function of the cell phone in cooperation with the cell phone, and a method of expanding the function of the cell phone using the same.

The functional case applied to the present invention may be embodied in such a manner as to cover at least one of the front surface, the outer surface (upper and lower left and right), and the rear surface of the mobile terminal. The functional case may be a structure that can be opened or closed in the form of a wallet or a structure that encloses other surfaces except the front surface. Such a functional case may be referred to as "Appsport ".

Eight terminals are provided on the inner side of the functional case. When the mobile terminal is mounted on the mobile terminal instead of the rear case of the mobile terminal, the terminal is in contact with eight terminals provided at the lower end of the mobile terminal. The functional case may be separately purchased and mounted on the mobile terminal, and the rear case of the mobile terminal is detached and installed instead.

Therefore, if the function case (cover) according to the present invention is provided with a function or an element capable of expanding the function of the mobile phone, if the function case is mounted on the mobile terminal, the terminal of the function case and the terminal of the mobile terminal are connected So that it is possible to perform an interlocking operation with the mobile terminal.

However, the present invention is not limited thereto. In another embodiment, the present invention may have eight terminals on the bottom surface of the rear case so as to be connected to the terminal of another functional case.

The function may include a security function, a scan function, a voice recording function, a constant display function, a handwriting function, and may include a fingerprint sensor, a wireless earpiece (phone), a speaker, a scanner, a hardware key, .

3 is a flowchart illustrating a function expansion method of a mobile terminal using a function case according to an embodiment of the present invention.

As shown in FIG. 3, after removing the rear case of the mobile terminal (S100), the user attaches the function case having the desired function to the mobile terminal instead of the separated rear case (S110).

When the functional case is installed in the mobile terminal, the controller 180 of the mobile terminal performs the functions of the functional case by interlocking the mobile terminal and the functional case to expand the function of the mobile terminal (S120).

Various embodiments of the functional case according to the present invention will be described below.

In recent years, mobile financial transactions have become commonplace, using a number of security cards / OTPs a day. In this case, the user must confirm the security card number. However, there is a problem that the user has to carry the OTP at all times for an unspecified mobile financial transaction, and the security number is vulnerable because the number is exposed to the surrounding area when the security card number is input.

In general, the fingerprint sensor (module) has a close relationship with security such as payment and unlocking, which makes the entry barriers in the general accessory market higher than other accessories. Therefore, when the password / ID input, payment and unlocking are processed by fingerprint recognition, the reliability of the user confirmation is enhanced and the complicated input procedure can be simplified. Especially, since it is certain that fingerprint recognition will be applied to various mobile settlement (eg, Apple Pay, Google Wallet, Ali Pay and PayPal payment) recently, it is expected that the mounting of fingerprint sensors will be greatly expanded in mobile terminals.

However, when the fingerprint sensor is mounted on the mobile terminal, the manufacturing cost of the mobile terminal is increased.

Therefore, according to the present invention, a fingerprint recognition sensor (module) is purchased and installed in a function (mobile phone) case that encloses the front or rear surface of the mobile terminal, Security / financial transactions. This mobile phone case is referred to as a " security case ".

4 and 5 illustrate an automatic login and unlock function using a security case.

4 and 5, the security case may include a fingerprint recognition sensor 50, and the user may mount a security case in place of the back case of the mobile terminal. The security case may have the same shape as that of the conventional back case as shown in FIG. 3, or may have a form of a wallet including a fingerprint recognition sensor 50 inside as shown in FIG.

When the user touches the fingerprint sensor 50 in this state, the fingerprint sensor 50 recognizes the fingerprint of the user and transmits the fingerprint to the controller 180 of the mobile terminal. Based on the recognized fingerprint, Automatically enter the user's ID / PWD to release the lock.

FIGS. 6 and 7 show embodiments in which the OTP function is performed using the security case.

The present invention can simultaneously perform a fingerprint recognition function and an OTP number automatic input function by mounting an OTP device (not shown) together with the fingerprint recognition module 50 on the front surface of the security case.

6 and 7, when the user touches the fingerprint recognition module 50 with the payment screen displayed on the display unit 151 of the mobile terminal, the fingerprint recognition sensor 50 displays the fingerprint of the user And automatically transmits the OTP number generated by the OTP device to the control unit 180 of the mobile terminal. The fingerprint recognition sensor 50 can display the fingerprint recognition status and the OTP issuance status through separate LEDs. That is, the control unit separately provided in the fingerprint recognition sensor 50 or the fingerprint recognition sensor 50 may output different colors of the lamps to intuitively display the fingerprint recognition status and the OTP issuance status to the user. In particular, fingerprint recognition and OTP number issue can be performed with different touch strengths. For example, when the user places a finger on the fingerprint recognition module 50, fingerprint recognition is performed, and if the fingerprint recognition is performed in this state, the OTP device can generate the OTP number. The generated fingerprint recognition result and the OTP number are individually transmitted to the controller 180 of the mobile terminal and input to the payment window.

Therefore, since the user can input the fingerprint recognition and the OTP number by a simple touch operation, there is an advantage that the OTP input time can be reduced while enhancing the security.

Meanwhile, when the security case (fingerprint recognition case) is used and the security case is disconnected from the mobile terminal, the lock screen can be released by inputting the alternative password registered together at the time of fingerprint registration.

In addition, the security case used in the present invention does not have any data but merely transmits the fingerprint to the mobile terminal, so it may be inserted into another mobile terminal.

As a result, if the distance between the users wearing the two wireless earphones is equal to or greater than a predetermined distance (e.g., 1 m), the wireless earset 60 is switched from the previous Bluetooth mode to the walkie-talkie mode. At this time, the two earsets perform a walkie-talkie function using a Bluetooth (short distance) (first distance), a radio (RF) signal a long distance (second distance), and a long distance .

The conversation between the two wireless ear sets is stored in the memory 170 of the mobile terminal.

On the other hand, when an event such as a notification, a message, an SNS, or a telephone call occurs, the controller 180 notifies an event to the earset close to the mobile terminal among the two wireless earphones.

The microphone provided in the wireless earset 60 is automatically turned on only when talking and automatically turned off when it is not talking to minimize the input of attention noise.

13, the control unit 180 of the mobile terminal displays the positions of the two wireless ear sets on the display unit 151 through the GPS sensor mounted on each wireless earset 60, 60) can be provided in real time.
