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.

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 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 mobile terminal 100 may operate in association with a web storage that performs the storage function of the memory 170 on the Internet.

Meanwhile, as described above, the control unit 180 controls the operations related to the application program and the general operation of the mobile terminal 100. [ For example, when the state of the mobile terminal meets a set condition, the control unit 180 can execute or release a lock state for restricting input of a user's control command to applications.

Meanwhile, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can determine whether the current position of the mobile terminal 100 is an important place for the user. For example, the control unit 180 can determine this based on the motion of the user. That is, when no motion is detected for a predetermined time or more, or when a predetermined abnormal motion is not detected for a predetermined number of times or more as a result of the motion detection, It can be judged that it is stationary at the position where it is placed. If it is determined that the user is stationary, the location where the mobile terminal 100 is currently located may be determined as an important place having a specific meaning to the user, i.e., a user location.

The 'user location' set in this way may correspond to at least one function executable in the mobile terminal 100. In this case, the control unit 180 determines whether the current location of the mobile terminal 100 is one of preset user locations, and automatically performs at least one function corresponding to the user location according to the determination result have.

For this, the controller 180 may use various methods for identifying the location of the mobile terminal 100. [ For example, the controller 180 may use the signal characteristics received from the mobile terminal 100 peripherals. These peripheral devices may be APs (Access Points) connectable to the mobile terminal 100. The mobile terminal 100 according to the embodiment of the present invention can identify the location of the mobile terminal 100 based on signal characteristics received from a plurality of APs that can be detected. That is, the controller 180 analyzes the signal characteristics of neighboring APs that are detected differently according to the location of the mobile terminal 100, and determines whether the analyzed pattern is a characteristic pattern (hereinafter referred to as an AP characteristic pattern) , It can be determined that the location where the mobile terminal 100 is currently located is the predetermined user location.

In this case, the control unit 180 determines that the pattern analyzed from the signals obtained from the neighboring APs is matched when the pattern is similar to the characteristic pattern of the predetermined user place by a predetermined level or more, It is needless to say that the characteristics of the radio signal may be supplemented.

Meanwhile, at least one function corresponding to the user location may include a function of switching the operation state of the mobile terminal 100. Here, the operation state may be a state for performing a specific function, or a graphical object related to execution of a plurality of predetermined different functions may be displayed on at least one of the background images displayed on the display unit 151 of the mobile terminal 100 It may mean a state that is displayed on a part thereof. Or a predetermined state in which at least one specific function executable in the mobile terminal 100 is limited (for example, a mute state - a ringing output function is limited), or a state in which predetermined peripheral devices (e.g., Access Point) is registered in advance, and the specific peripheral devices and the mobile terminal 100 are automatically connected to each other. At least one function corresponding to each user location and information on the AP characteristic pattern obtained at each user location may be stored in the memory 170. [

In the following description, it is assumed that a specific function executed in a specific user place in the mobile terminal 100 according to an embodiment of the present invention is a function of switching the operation state of the mobile terminal 100 as described above. However, it should be understood that the present invention is not limited thereto.

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.

FIG. 2 is a flowchart illustrating an operation of switching to a specific operation state based on characteristics of signals received from nearby APs in a mobile terminal related to the present invention.

First, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can detect whether the user moves or not (S200). In step S200, the control unit 180 controls the sensing unit 140 according to a predetermined application or program, and can detect the movement of the user based on the sensing result collected from the sensing unit 140. [ Here, the predetermined application or program may be configured to be driven in the form of a back ground program, or may be set to be driven together when the mobile terminal 100 is driven. The application or program may be an application or a program separately provided for the operation of step S200 or provided for other purposes. That is, the control unit 180 may detect whether there is a movement of the user in step S200 by using the healthcare program or the detection result collected through the application provided for the health management of the user.

Meanwhile, in step S200, the controller 180 not only detects the motion but also detects the motion of the user when the motion size of the user is less than a predetermined level, or when the motion is detected but the motion is not detected again or the motion It is of course possible to determine that no motion is detected when the detected number of times is less than the predetermined number of times. This is to prevent the temporary change of the position of the mobile terminal 100 from being detected as a movement of the user when the user accidentally changes the position of the mobile terminal 100 .

In operation S202, the controller 180 may determine whether the time when the motion is not detected is greater than a predetermined time as a result of the detection in operation S200. In step S202, it is determined whether the user is in a specific place. When the user completes entry into a specific place, for example, a user's seat or a specific conference room in the office, To be detected.

Accordingly, if it is determined in step S202 that the time when the motion is not detected is less than a predetermined time, the controller 180 may determine that the user has not completed entry into the specific place. Accordingly, the control unit 180 may proceed again to step S200 to detect whether there is a motion.

However, if it is determined in step S202 that the time when the motion is not detected is longer than the predetermined time, the controller 180 may determine that the user has entered the specific place. The control unit 180 may determine whether the current location of the mobile terminal 100 is a predetermined location. For this, the controller 180 may use the characteristics of signals received from the peripheral devices detectable by the mobile terminal 100. For example, these peripherals can be APs, so that the controller 180 can collect signals received from nearby perceptible APs and analyze the characteristics of each AP based on the collected signals S204). Here, the characteristics of the APs may include a received signal strength indicator (RSSI) of signals received from the APs.

In step S206, the control unit 180 may generate an AP characteristic pattern corresponding to the current position of the mobile terminal 100 based on the characteristics of the APs analyzed in step S204. The AP characteristic pattern may be generated based on the number of APs detectable at the current position of the mobile terminal 100, the number of APs, and the characteristics of each AP analyzed in step S204. Since the AP characteristic pattern can reflect the characteristics of the mobile terminal 100 according to the position where the mobile terminal 100 is placed, such as an adjacent AP or a previously installed obstacle, information that can estimate the position of the mobile terminal 100 .

Accordingly, the control unit 180 can determine whether the current location of the mobile terminal 100 is a predetermined user location based on the AP characteristic pattern.

Meanwhile, the AP characteristic pattern may further include an order of the APs that can be detected, and may further include information related to an installation location of the APs when information on the installed location of the APs is present. Hereinafter, an AP characteristic pattern generated by using information on the locations where the APs are installed will be described in more detail with reference to FIG.

Meanwhile, when the AP characteristic pattern is generated in step S206, the controller 180 may determine whether there is a user location corresponding to the currently generated AP characteristic pattern (S208). In step S208, the AP characteristic pattern generated in step S206 may be compared with at least one pre-stored AP characteristic pattern to determine whether there is an AP characteristic pattern similar or similar to a predetermined level or higher. have. Here, the at least one pre-stored AP characteristic pattern may correspond to a different user location. Table 1 below shows examples of pre-stored AP characteristic patterns corresponding to different user locations.

AP
Place A B C D E Meeting Room 1 -50dB -50dB -60dB -70dB -70dB Meeting Room 2 -72dB -65dB -60dB -45dB -48dB Meeting Room 3 -62dB -61dB -60dB -59dB -58dB

(AP: Access Point, db: desibel, location: user location)

These user locations may be pre-registered by the user. That is, the control unit 180 can select whether to register the user's place based on whether the predetermined condition is satisfied or not. The predetermined condition may be the number of times a pattern identical to the currently generated pattern or a pattern similar to a predetermined level or more is generated, or the like. That is, when a pattern identical or similar to the currently generated pattern is generated more than a predetermined number of times, the controller 180 can determine that a new user location is found, and can notify the user of the new user location. The AP characteristic pattern generated over the predetermined number of times may be registered in a pattern corresponding to a new user location according to a user's selection.

Hereinafter, when the AP characteristic pattern is generated, an operation procedure of registering a new user place based on the AP characteristic pattern will be described in detail with reference to FIG.

Meanwhile, according to the above description, even if the AP characteristic pattern generated in step S206 is similar to the pre-stored AP characteristic pattern by a predetermined level or more, the control unit 180 determines that the current location of the mobile station 100 As shown in FIG. For this, the control unit 180 can determine the similarity by various methods. For example, the control unit 180 may determine similarity according to characteristics of a graph generated from the generated AP characteristic pattern or by setting a predetermined similar range for each AP. Or the location of the mobile terminal 100 estimated from the installed location of the APs when there is information on the installation location of the predetermined APs. Hereinafter, a process of determining similarity in various ways will be described in detail with reference to FIG. 5 and FIGS. 6A and 6B.

On the other hand, if it is determined in step S208 that there is no pre-stored AP characteristic pattern matching with the pattern generated in step S206, the controller 180 determines that there is no user location corresponding to the current position of the mobile terminal 100 It can be judged. Then, the controller 180 may return to step S200 to detect whether there is motion. On the other hand, if there is no pre-stored AP characteristic pattern matched to the pattern generated in step S206, the controller 180 determines whether a pattern of the same or similar pattern generated in step S206 is generated a predetermined number of times or more, It goes without saying that the place may be registered by the user.

On the other hand, if it is determined in step S208 that there is a pre-stored AP characteristic pattern matching the pattern generated in step S206, the controller 180 determines whether the current location of the mobile terminal 100 corresponds to one of the pre- . Accordingly, the control unit 180 may perform at least one function set in the user location corresponding to the current location of the mobile terminal 100 (S210).

The at least one predetermined function may include a function of switching the operation state of the mobile terminal 100. That is, if there is a pre-stored user location corresponding to the AP characteristic pattern generated in step S206 and there is a specific operation state corresponding to the user location, the controller 180 determines whether the mobile terminal 100 The operation state can be switched to the specific operation state. Here, the specific operation state may include a state in which a specific function is performed, a state in which graphical objects related to execution of a plurality of predetermined functions are displayed, a state in which at least one specific function executable in the mobile terminal 100 is restricted, And a state in which the mobile terminal 100 and the specific peripheral devices are automatically connected to each other.

When the mobile terminal 100 is switched to a specific operation state or enters an operation state for performing at least one specific function, the controller 180 may detect the movement of the user again. This is for judging whether or not the mobile terminal 100 has departed from the current position, i.e., the user's place, according to the movement of the user. In step S212, the control unit 180 may switch the operation state changed in step S210 back to a predetermined operation state based on whether or not the user's location is deviated. Here, the predetermined operation state may be an operation state before switching in step S210, or an operation state preset in a basic state by the user (hereinafter referred to as a basic operation state).

Meanwhile, in step S212, the controller 180 may use various methods to determine whether the mobile terminal 100 leaves the preset user location. For example, the control unit 180 compares an AP characteristic pattern generated from neighboring APs that can be detected with an AP characteristic pattern corresponding to an operation state of the current mobile terminal 100, It is possible to determine whether or not the user has left the place. The process of determining whether the mobile terminal 100 leaves the user's place according to the motion detection result in step S212 and switching the operation state to the predetermined basic operation state according to the result is described in detail with reference to FIG. Let's look at it.

On the other hand, if the basic operation state is changed to the basic operation state in step S212, the controller 180 may proceed to step S200 and step S202 to determine whether the time when the motion is not detected is longer than a predetermined time. The above-described processes of FIG. 2 can be repeatedly performed according to the determination result.

As described above, when the mobile terminal 100 is switched to the specific operation state, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention determines whether or not the user's location is deviated based on the AP characteristic pattern generated from surrounding APs Can be determined. And Figure 3 shows this process in more detail.

Referring to FIG. 3, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention detects whether the user moves or not when the mobile terminal 100 is switched to the specific operation state in step S210 of FIG. (S300). The step S300 may be detected through an application or a program such as the step S200 of FIG. 2 (for example, a healthcare application). In addition, in step S300, the controller 180 may determine that the motion is detected only when the magnitude of the motion of the user to be sensed is equal to or greater than a preset level, or when motion is detected over a predetermined number of times within a preset time have.

Meanwhile, if it is determined in step S300 that there is movement, the controller 180 analyzes the characteristics of APs that can be detected from the current mobile terminal 100 and generates an AP characteristic pattern corresponding to the analyzed result (S302) . Here, the step S302 may be performed in a similar manner to the step S206 of FIG. In addition, the step S302 may be performed after a certain period of time has elapsed since the movement was detected in step S300, taking into consideration the time required for the user to move from the user's place corresponding to the current position.

 The controller 180 may compare the AP characteristic pattern generated in step S302 with the AP characteristic pattern corresponding to the current operation state of the mobile terminal 100 in step S304. The control unit 180 controls the AP characteristic pattern corresponding to the current operation state of the mobile terminal 100, that is, the AP characteristic pattern according to the user location corresponding to the current location of the mobile terminal 100, It is determined that the position of the current mobile terminal 100 does not deviate from the region set as the user's location if the two patterns are equal to each other or equal to a predetermined level or more (S306). Then, the controller 180 proceeds to step S300 to detect the motion, and repeats steps S302 to S306 according to the detection result.

On the other hand, if the two patterns are not identical or equal to each other at step S306, the controller 180 may determine that the mobile terminal 100 has left the current user location. Accordingly, the control unit 180 can switch to the predetermined basic operation state (S308), and can go back to the step S200 of FIG. 2 to determine whether the user has entered the specific place again.

Meanwhile, FIG. 4 is a flowchart illustrating a process of updating a AP characteristic pattern corresponding to a registration of a new user location or a previously registered user location based on collected signal characteristics in a mobile terminal according to the present invention.

4, when the AP characteristic pattern is generated from the APs detectable at the current position of the mobile terminal 100, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention generates a pattern May be classified and stored in the same or similar pattern (S400). In step S400, the determination of the same or similar can be made by various methods. For example, the determination of the same or similar may be made based on AP similarity patterns determined for each AP, or AP characteristic patterns generated in a graph form. Or the user location area estimated based on the installation location of the APs and the strength of signals received from each of the APs.

If the AP characteristic patterns generated for the same or similar patterns are classified and stored in step S400, the controller 180 may determine whether there is a user location corresponding to the currently generated AP characteristic pattern (step S402) . If there is a user location corresponding to the currently generated AP characteristic pattern, the control unit 180 may update the similar range of the pattern corresponding to the user location by reflecting the currently generated pattern (S404).

For example, if the pre-stored user location and AP characteristic patterns of the APs corresponding to the respective user locations are the same as those shown in Table 1, the controller 180 stores the pre- (S404). For example, the characteristics of each AP in the pre-stored AP characteristic pattern shown in Table 1, for example, the signal strength may be determined based on the signal intensity of each AP included in the AP characteristic patterns classified and stored equal to or more than a predetermined number . ≪ / RTI > In this case, when a new AP characteristic pattern is generated, the controller 180 calculates average values of AP characteristics corresponding to the location of the corresponding user, You can update the values of the pattern. Accordingly, the similar range of each AP in the AP characteristic pattern corresponding to the user location can be also updated.

On the other hand, if it is determined in step S402 that there is no user location corresponding to the currently generated pattern, the controller 180 determines whether the number of AP characteristic patterns classified by the same or similar patterns in step S400 is greater than or equal to a predetermined number It is possible to confirm whether or not the pattern exists (S406). If it is determined in step S406 that there are more than a predetermined number of stored AP characteristic patterns, the controller 180 may determine that a new user location is found.

In operation S408, the control unit 180 may display information on the detected new user location and select whether to register the detected location as a user location. Hereinafter, examples of a user interface screen for registering a new user place according to a user's selection will be described in more detail with reference to FIG.

The control unit 180 of the mobile terminal 100 according to the present invention may set a predefined similarity range for each AP so that the AP characteristic pattern generated at the position of the pseudo current mobile terminal 100 And whether or not the previously stored AP characteristic pattern is the same or similar.

For example, the control unit 180 may set a similar range in advance for each AP, and the characteristics of each AP (for example, the received signal strength received from each AP) may be stored in the previously stored AP characteristic If there is a pattern, it may be determined that there is a corresponding user place. For example, if it is assumed that a similar range of -2db to +2 db is set for each AP, the controller 180 may set the AP characteristic pattern corresponding to each user location as shown in Table 2 below.

AP
Place A B C D E Meeting Room 1 -52 to -48 -52 to -48 -62 to -58 -72 to -68 -72 to -68 Meeting Room 2 -74 to -70 -67 to -63 -62 to -58 -47 to -43 -46 ~ -50 Meeting Room 3 -64 to -60 -63 to -59 -62 to -58 -61 to -57 -56 ~ -60

(Unit: db)

Accordingly, even if the AP characteristic pattern generated at the current location of the mobile terminal 100 does not exactly coincide with any one of the AP characteristic patterns shown in Table 1, the controller 180 determines at least some AP characteristics (received signal strength) Is included in the similar judgment range set for each AP, it can be determined that the two AP characteristic patterns are similar to each other.

On the other hand, the controller 180 can determine similarity of the AP characteristic pattern by various methods as well. For example, the control unit 180 assigns a predetermined order to each AP, and may determine similarity based on a graph generated according to the listed order (hereinafter, referred to as an AP characteristic pattern graph).

FIG. 5 shows an example of a graph generated based on the order given to each AP and AP characteristics included in each AP characteristic pattern.

Referring to FIG. 5, the first graph 500 shown in FIG. 5 shows an example of a graph generated according to the AP characteristic pattern corresponding to 'conference room 1' among the user places in Table 1, The third graph 520 shows an example of a graph generated according to the AP characteristic pattern corresponding to the 'meeting room 2' among the user places shown in Table 1, The AP characteristic pattern corresponding to the AP characteristic pattern shown in FIG.

On the other hand, if the AP characteristic pattern according to the current position of the mobile terminal 100 is generated in step S206 of FIG. 2 or S302 of FIG. 3, the controller 180 may graph have. The generated graph may be compared with the characteristics of the graphs corresponding to the pre-stored AP characteristic patterns to determine whether there is the same or similar graph.

For example, the control unit 180 may determine whether the respective graphs are inclined or inclined, a point at which a change of more than a predetermined level occurs in each graph (for example, AP 'B' and 'D' A point corresponding to the signal intensity of AP 'D' in the second graph 510), and the like can be characteristics of each graph. And the graphs in which the characteristics at least partially coincide with each other may be determined to be the same or similar to each other.

Therefore, even if a certain level change occurs, if the characteristics coincide with each other by a predetermined level or more, they can be judged as similar graphs. For example, in the case of Table 1, it is assumed that there are five APs at a user location corresponding to 'conference room 1.' However, if one AP (for example, AP 'E' 1 ' may be as shown in Table 3 below.

AP
Place A B C D E F Meeting Room 1 -50dB -50dB -60dB -70dB -70dB -60dB

In this case, if the mobile terminal 100 is located in the user's 'conference room 1', the AP characteristic pattern graph generated in step S206 of FIG. 2 or S302 of FIG. May be a form in which a graph is newly added corresponding to the AP 'F'. However, even if such a change occurs, the characteristic of the first graph 500, that is, the direction in which the graph is inclined or inclined, a point at which a change over a predetermined level occurs, The control unit 180 determines that the two graphs are similar to each other as the points corresponding to the signal strengths of B 'and D' match the graphs generated in the first graph 500 and the 'conference room 1' can do. Accordingly, the controller 180 may switch the operation state of the mobile terminal 100 to the current location of the mobile terminal 100, that is, an operation state corresponding to the user's 'conference room 1'.

Meanwhile, according to the above description, if there is information on the installation location of the predetermined APs, it is possible to determine the similarity according to the location of the mobile terminal 100 estimated from the installed location of the APs have. The information on the location of the predetermined APs may be transmitted from the AP to the mobile terminal 100 when the mobile terminal 100 is connected to any one of the APs, Or may be transmitted from an external server. Also, the location information of the APs may further include information on an indoor area where the mobile terminal 100 is currently located, that is, drawing information showing an indoor area, and the like.

FIG. 6A illustrates an example of forming an area for determining whether or not the AP characteristic pattern is similar using the information about the installation location of APs.

Referring to FIG. 6A, FIG. 6A shows a case where six APs (A 600, B 620, C 630, D 640, E 650, and F 660) And shows that signals are received from different APs at different intensities. In this case, the control unit 180 may calculate distances between the APs from the signals of the APs received from the current position of the mobile terminal 100, and may calculate the distances between the APs based on the positions where the APs are installed, 0.0 > 670 < / RTI >

The control unit 180 may determine whether the mobile terminal 100 is located at a preset user location based on the calculated current location of the mobile terminal 100. [ That is, the controller 180 can determine whether the estimated location of the mobile terminal 100 is included in a predetermined area as a user location, and move to an operation state corresponding to the user location according to the determination result The operation state of the terminal can be switched.

6A, when a location 670 of the mobile terminal 100 is estimated, a new user location corresponding to the location 670 of the mobile terminal 100 (hereafter referred to as a first user location) is registered The area 680 formed around the position of the mobile terminal 100 may be an area corresponding to the first user location.

That is, as shown in FIG. 6B showing the formed region 680 in more detail, a certain region is formed as a region 680 corresponding to the first user place around the position 670 of the mobile terminal 100 . The strengths of the signals received from the APs 610, 620, 630, 640, 650 and 660, that is, the position of the mobile terminal 100 estimated from the AP characteristic pattern, The control unit 180 can determine that the mobile terminal 100 has entered the first user place in the case where the mobile terminal 100 is included in the first location 680 (e.g., the respective locations 670, 670a to 670i in FIG. 6B) . The control unit 180 may switch the operation state of the mobile terminal 100 to an operation state or a specific operation state in which at least one function corresponding to the first user location is performed.

Meanwhile, FIG. 7 shows examples of a user interface screen displayed when the mobile terminal is switched to a specific operation state according to the location of the mobile terminal.

7, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention determines whether or not the time when the motion is not detected is greater than or equal to a predetermined time in steps S200 and S202 of FIG. 7, it is possible to search for a user place corresponding to the current position of the mobile terminal 100, as shown in the first drawing of FIG. Here, the control unit 180 of the mobile terminal 100 determines whether the AP characteristic pattern formed from the characteristics of the APs detectable from the mobile terminal 100, for example, the strength of signals received from the APs, It is possible to search for a user place corresponding to the current location of the mobile terminal 100, based on whether or not the location information matches the stored AP characteristic pattern.

On the other hand, if there is an AP characteristic pattern of a user's location previously stored in the AP characteristic pattern generated from the searched user location, i.e., the current location of the mobile terminal 100, Can be displayed on the display unit 151. [0156] FIG. 7, a menu screen 710 for confirming whether the user's location currently searched from the user is the current location of the mobile terminal 100 can be displayed on at least a part of the display unit 151 have.
