That is, the predetermined distance may not be a separately designated value regarding a distance or a signal strength limitation between the wireless device and the portable terminal 100, and may indicate a communication radius through which the wireless device is searched. If the wireless device is not detected within a predetermined distance in step 910, in step 915, the mobile terminal 100 may display a screen for requesting unlocking when the screen is switched from the turned off state to the turned state.

When the wireless device is searched within a predetermined distance around the portable terminal 100, in step 925, the portable terminal 100 may check whether the identification information of the searched wireless device matches the stored identification information. If the discovered identification information of the wireless device does not match the stored identification information, the portable terminal 100 may operate by entering step 915.

If the identification information of the discovered wireless device matches the stored identification information, and the screen of the mobile terminal 100 is turned off in step 930, the mobile terminal 100 in step 935 is turned on while the screen is turned off. When switching to the state, it is possible to control so that the unlock request screen is not displayed.

If the identification information of the searched wireless device matches the stored identification information, and the screen of the mobile terminal 100 is turned on in step 930, the mobile terminal 100 enters step 1005 of FIG. 10 to operate. can do.

Referring to FIG. 10, a method of controlling a screen state using a wireless device in a state in which the screen of the portable terminal 100 is turned on is described in connection with a method of controlling screen lock. When the screen 150 is turned on, the control unit 150 of the mobile terminal 100 continues to search for a wireless device having identification information matching the stored identification information within a certain distance, and then displays the screen from the user of the mobile terminal 100. It can be controlled to keep the screen on without an unlock request screen until an input is received. In addition, if the identification information is not received from the wireless device for a preset time while the screen is on, the controller 150 may control the screen to be switched from the on to the off.

In step 1005, the portable terminal 100 may determine whether identification information matching the stored identification information is received from a wireless device located within a predetermined distance around the portable terminal 100 for a preset time. Here, step 1005 may indicate steps 920 and 925 described above.

If the wireless device is not searched within a predetermined distance around the portable terminal 100 in step 1005 or the identification information of the searched wireless device does not match the stored identification information, the portable terminal in step 1010 ( 100) can switch the screen from the on state to the off state. After step 1010, the mobile terminal 100 may enter and operate in step 915 of FIG. 9.

If the wireless device is searched within a predetermined distance around the portable terminal 100 in step 1005, and the identification information of the searched wireless device matches the stored identification information, in step 1015, the portable terminal 100 displays the screen. It can be controlled to remain lit.

In step 1020, the mobile terminal 100 may check whether the screen off input is received through the user interface unit 135. The screen off input may be, for example, a user input received through the power button 560 in FIG. 6. When the screen off input is received, the mobile terminal 100 may enter step 1010 to switch the screen from the on state to the off state.

If the screen off input is not received, in step 1025, the mobile terminal 100 may check whether a preset time has elapsed. If the preset time has not elapsed, in step 1015, the mobile terminal 100 may control the screen to remain on. When the preset time has elapsed, the mobile terminal 100 may enter the step 1005 again and operate.

11 and 12, a method of controlling screen lock using a wireless device according to another aspect of the present invention will be described.

The mobile terminal 100 may provide a user interface for setting a screen unlock mode using a wireless device (eg, the BLE device 200). The mobile terminal 100 may store at least one sensing condition specified through a user interface (eg, 1630 of FIG. 16 or 17) or a preset sensing condition of the mobile terminal 100. The sensing unit 140 of the mobile terminal 100 may acquire sensing information related to the stored sensing conditions. For example, the sensing condition may indicate that the movement of the mobile terminal 100 is a preset movement type. As an example, the preset motion type may be a'pick-up motion' designated through a user interface (1630 in FIG. 16 or FIG. 17). Referring to FIG. 11, the mobile terminal 100 may detect the movement 1110 of the mobile terminal 100 and obtain sensing information about the movement type. Accordingly, the portable terminal 100 may determine whether the obtained sensing information satisfies the sensing condition by determining whether the movement 1110 of the portable terminal 100 indicates a pickup motion.

In step 1205 of FIG. 12, the portable terminal 100 may provide a user interface for setting a screen unlock mode using a wireless device (eg, the BLE device 200 ).

In step 1210, the portable terminal 100 may store the designated sensing condition and identification information of the wireless device through the user interface.

In step 1220, the portable terminal 100 may determine whether the wireless device is searched within a certain distance. Here, the predetermined distance may not be a separately designated value regarding a distance or a signal strength limitation between the wireless device and the portable terminal 100, and may indicate a communication radius through which the wireless device is searched. If the wireless device is not searched within a certain distance, in step 1215, the portable terminal 100 may control to display the unlock request screen when the screen is switched from the off state to the on state.

If the wireless device is searched within a certain distance, in step 1225, the portable terminal 100 may check whether the identification information of the searched wireless device matches the stored identification information. If the identification information of the discovered wireless device and the stored identification information do not match, the portable terminal 100 may operate by entering step 1215.

If the identification information of the discovered wireless device and the stored identification information match, the mobile terminal 100 may acquire sensing information of the mobile terminal 100 in step 1230. Also, the step 1230 may be performed regardless of whether or not the conditions of the steps 1220 and 1225 are satisfied or the order. For example, step 1230 may be performed when a wireless device having identification information matching the stored identification information regardless of distance is searched, or performed according to a certain period when the screen of the portable terminal 100 is turned off. It may be.

In step 1235, the mobile terminal 100 may determine whether the obtained sensing information satisfies the sensing condition. If the obtained sensing information does not satisfy the sensing condition, the portable terminal 100 may operate by entering step 1215.

If the obtained sensing information satisfies the sensing condition, in step 1240, the mobile terminal 100 may control the screen to display the unlock request screen when the screen is switched from the off state to the on state.

Also, the portable terminal 100 may control the screen state using sensing information of the wireless device and the portable terminal 100 while the screen is turned on. For example, the controller 150 of the mobile terminal 100 continues to search for a wireless device having identification information matching the stored identification information within a certain distance while the screen is turned on, and the obtained sensing information is sensed. If the condition is satisfied, it may be controlled to maintain the screen on without the unlock screen until a screen off input is received from the user of the portable terminal 100. In addition, the control unit 150, when the screen is turned on for a predetermined time, when the identification information is not received from the wireless device, or the obtained sensing information does not satisfy the sensing condition, so that the screen is switched from the on state to the off state Can be controlled.

For example, the sensing condition may indicate that the movement of the wireless device is a preset movement type. For example, the preset movement type may be “shake 2 times” designated through a user interface (1635 in FIG. 16 or FIG. 17). Further, the sensing condition may indicate a touch gesture for touching the wireless device. As an example, the touch gesture may be a “twice touch” during a specific time period, which indicates that the wireless device is touched twice consecutively with “knockknock” according to a user input. In FIG. 13, the sensing unit 240 of the BLE device 200 may obtain sensing information by detecting a user input 1310 for the BLE device 200. At this time, the sensing unit 240 may be configured using a touch sensor, a pressure sensor or a motion sensor. The BLE device 200 may broadcast the obtained sensing information or transmit it to the portable terminal 100.

If the identification information of the discovered wireless device does not match the stored identification information, the portable terminal 100 may operate by entering step 1415.

When the identification information of the discovered wireless device and the stored identification information match, the mobile terminal 100 may receive sensing information of the wireless device from the wireless device in step 1430. Here, the sensing information of the wireless device may be transmitted together with the identification information of the wireless device from the wireless device, or may be transmitted separately from the identification information. In addition, sensing information of the wireless device may be broadcast by being inserted into a manufacturer specific data (MSD) field of an advertising packet.

In step 1435, the mobile terminal 100 may determine whether the received sensing information satisfies the sensing condition. If the received sensing information does not satisfy the sensing condition, the mobile terminal 100 may operate by entering step 1415.

Also, the mobile terminal 100 may control the screen state using identification information and sensing information of the wireless device while the screen is turned on. For example, the controller 150 of the portable terminal 100 continues to search for a wireless device having identification information matching the stored identification information within a certain distance while the screen is turned on, and sensing received from the wireless device When the information satisfies the sensing condition, it may be controlled to maintain the screen on without the unlock request screen until a screen off input is received from the user of the portable terminal 100. In addition, the control unit 150, when the screen is turned on for a predetermined time, when the identification information is not received from the wireless device, or the received sensing information does not satisfy the sensing condition, so that the screen is switched from the on state to the off state Can be controlled.

Also, the portable terminal 100 may control screen lock by using identification information of the wireless device, sensing information of the portable terminal 100 and sensing information of the wireless device together. For example, the mobile terminal 100 may set and store sensing conditions of the mobile terminal 100 and sensing conditions of the wireless device through a user interface (1630, 1635 in FIG. 16 or FIG. 17 ). When the wireless device having identification information matching the stored identification information is searched within a certain distance, and satisfies the sensing condition of the portable terminal 100 and the sensing condition of the wireless device, the portable terminal 100 is turned on in the turned off state When switching to, you can control so that the unlock request screen is not displayed.
