The wireless communication unit 110 of the mobile terminal 100 may receive a message from the electronic device. Here, the message may include a message received using at least one of a Short Message Service (SMS) and a Multimedia Message Service (MMS).

The message received from the electronic device may include the authentication information, the control command may be included, or the authentication information and the control command may be included together.

Meanwhile, the wireless communication unit 110 may receive information from an electronic device in a manner other than a message. For example, the wireless communication unit 110 may receive information through a video call while performing a video call with an electronic device, or may receive information through a voice call while performing a voice call with the electronic device.

Here, the electronic device may be an electronic device previously set by the user of the mobile terminal 100, or may be any electronic device not previously set by the user. If the user desires to make a remote connection only between the mobile terminal 100 and the predetermined electronic device, when the wireless communication unit 110 receives the authentication information from the electronic device not previously set, the control unit 180 transmits the received authentication information Can be ignored.

Next, the user authentication is performed using the authentication information received from the electronic device (S120).

As described above, the authentication information may be included in a message received from the electronic device. Also, the authentication information may be received via a method other than a message. The authentication information may be included in the form of text data, or may be included in at least one of image data and voice data.

When the authentication information is included in the message in the form of text data, the authentication unit 182 can determine whether or not text data used as authentication information is included in the message received from the electronic device. If the received message includes text data, the authentication unit 182 can perform user authentication. In addition, the authentication unit 182 may transmit a message to the electronic device informing that the user authentication has been performed.

If text data is not included in the received message, the authentication unit 182 may transmit a message to the electronic device indicating that the user authentication has failed, without performing the user authentication. When a message including text data other than the text data used as the authentication information is received a predetermined number of times or more, the authentication unit 182 may store the identification information of the electronic device in the black list.

Thereafter, when user authentication is performed, a control operation is performed in response to a control command included in the received message (S130), and a message informing the result of the control operation is transmitted to the electronic device (S140) .

As described above, the control command can be included in the message received from the electronic device. Also, the control command may be received via a method other than a message. In addition, the control command may be included in the message in the form of text data, or may be included in the message in the form of at least one of image data and voice data.

The control command may be received by the control unit 180 in the form of a recognizable language, but may be received in a natural language form. When the control command is received in a natural language form, the control unit 180 can extract the control command included in the received message using a Natural Language Processing (NLP) algorithm.

The natural language processing algorithm means an artificial intelligence technology for the mobile terminal 100 or the computer to understand, generate and analyze a human language. Natural language understanding work refers to a task of converting a daily life language of a person so that the mobile terminal 100 or the computer can process it through morphological analysis, semantic analysis, and dialog analysis.

When the control command is extracted through the natural language processing algorithm, the control unit 180 can perform the control operation using the extracted control command.

For example, the control unit 180 detects at least one of the information related to the generated event and the information stored in the memory 160 (see FIG. 1) based on the control command, Can be transmitted to the device.

Further, the control unit 180 may install a new application or change the user interface of the home screen based on the control command.

As described above, according to the present invention, the mobile terminal 100 can perform user authentication of the electronic device using the text data included in the message received from the electronic device. That is, since the user authentication can be performed without complicated authentication procedure, the user's operation can be reduced in the authentication procedure. As a result, battery resources of the mobile terminal 100 can be efficiently used.

Also, according to the present invention, the mobile terminal 100 can be controlled using an electronic device even when the mobile terminal 100 is far away from the electronic device. Accordingly, even if the user can not use the mobile terminal 100, the user can inquire the event information generated in the user's mobile terminal 100 by using the electronic device (e.g., tablet PC or another user's mobile terminal) . As a result, the convenience of the user can be improved.

4 is a flowchart for explaining an embodiment of performing user authentication of an electronic device. 1), a control unit 180 (see FIG. 1), and a display unit 151 (see FIG. 1). The mobile terminal 100 includes a wireless communication unit 110 do.

Referring to FIG. 4, in operation S210, a message including authentication information is received from an electronic device. Here, the contents already described with reference to FIG. 3 will be omitted.

Next, in step S220, it is determined whether or not the first text data is included in the message.

As described above, the authentication information can be included in the message in various forms. When the authentication information is included in the message in the form of text data, the authentication unit 182 can determine whether the first text data preset in the message received from the electronic device is included.

If the received message does not include the first text data, the authentication unit 182 may determine that the message to be received subsequently is a general message (S240).

On the other hand, if the received message includes the preset first text data, the authentication unit 182 can determine whether the received text includes the second text data used as the password (S230).

Here, the first text data and the second text data may be included in one message or in different messages, respectively. In the latter case, that is, when the received message does not include the second text data, the authentication unit 182 may determine whether or not the subsequent message includes the second text data used as the password have. That is, when the first text data is included in the received message, the authentication unit 182 can determine that the message to be received subsequently is an encrypted message for user authentication.

If the received text does not include the second text data, or if the received text does not include the second text data, the user authentication of the electronic device may fail (S260).

On the other hand, if the received message includes the second text data, or if the received message includes the second text data, the authentication unit 182 can perform user authentication of the electronic device (S250).

Although not shown, when the user authentication is performed, the wireless communication unit 110 may transmit a message to the electronic device indicating that user authentication has been performed. Similarly, when the user authentication fails, the wireless communication unit 110 may transmit a message to the electronic device indicating that the user authentication has failed.

5 is a conceptual diagram showing a setting screen of the mobile terminal 100 preceded by a remote connection with the electronic device. The mobile terminal 100 includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1), and a display unit 151.

The present invention can be performed using an Intelligent Agent (IA). Referring to FIG. 5, the controller 180 may receive condition information and setting information for remote connection with the electronic device.

As shown, the control unit 180 can be selected whether or not to use the IA remote information service. The embodiments of the present invention can be applied to the case where the user has checked the IA remote information service use item. On the other hand, if the user does not check the IA remote information service use item, the controller 180 may ignore the received authentication information and determine the message as a general message even if the wireless communication unit 110 receives the authentication information from the electronic device .

Although not shown, the control unit 180 may select an electronic device to use the IA remote information service. If the user desires to establish a remote connection only between the mobile terminal 100 and the predetermined electronic device, even if the wireless communication unit 110 receives the authentication information from the electronic device not previously set, Can be ignored.

Next, the control unit 180 can receive the IA connection password. The control unit 180 may receive the type of the IA connection password. The type of IA connection password may include at least one of, for example, text data, video data, and voice data.

Here, when text data is selected, a password including a predetermined character or number can be set. When the image data is selected, a fingerprint image or a face image of the user can be set. When voice data is selected, voice information of the user can be set.

Next, the control unit 180 can receive the password receiving method. The control unit 180 can provide the password to the user when the electronic device has been mistaken for the password more than a predetermined number of times. Here, the provided password may be a predetermined password or a new one-time password (OTP).

Next, the control unit 180 can receive the connection holding time. The connection holding time means a time required until the remote connection with the electronic device is terminated after the user authentication is performed. For example, if "3 minutes" is set, the remote connection with the electronic device may be automatically terminated after 3 minutes have elapsed since the authentication of the electronic device and the user.

6A and 6B are conceptual diagrams showing a user interface of the mobile terminal 100 when user authentication information of the electronic device is received. The mobile terminal 100 includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1), and a display unit 151.

The wireless communication unit 110 of the mobile terminal 100 may receive a message from the electronic device. The received message may include authentication information.

6A, when the first message 251 including the first text data (e.g., "High Optimus") is received from the electronic device, the authentication unit 182 The first message 251 may be determined as a message preceding the user authentication. That is, the authentication unit 182 may determine a message received from the electronic device as an encryption message for user authentication.

If the first text data is not included in the first message 251, the authentication unit 182 may determine that the message to be received subsequently is a general message.

Next, the wireless communication unit 110 may transmit the second message 252 requesting the authentication information to the electronic device. This step may be omitted. In addition, although not shown, the second message 252 may include hint information associated with the cipher.

Thereafter, when a third message 253 including second text data (for example, "123abc") used as a cipher from the electronic device is received, the authentication unit 182 determines that the second text data corresponds to the cipher . If it is determined that the second text data corresponds to the encryption, the authentication unit 182 can perform user authentication. Accordingly, the mobile terminal 100 and the electronic device can be connected remotely.

Next, the wireless communication unit 110 may transmit a fourth message 254 indicating that user authentication has been performed to the electronic device. This step may be omitted. Also, although not shown, a connection holding time (e.g., "3 minutes") may be indicated in the fourth message 254.

Also, referring to (b) of FIG. 6A, a third message 253 including an image of the user may be received from the electronic device. The authentication unit 182 compares the image of the received user with the predetermined image, and determines whether to perform user authentication.

Also, referring to (c) of FIG. 6A, a third message 253 including a user's fingerprint image may be received from the electronic device. The authentication unit 182 can compare the received fingerprint image with the predetermined fingerprint image and determine whether to perform user authentication.

6A, the wireless communication unit 110 includes a wireless communication unit 110 for inquiring about information related to the mobile terminal 100 (for example, "name of the party called at 10:00 am on October 20 & 2 message 252 to the electronic device. A user using the electronic device may transmit to the mobile terminal 100 a third message 253 including an answer to the question included in the second message 252 (e.g., "JANE").

Then, the authentication unit 182 can determine whether to perform user authentication based on the correctness of the answer included in the third message 253.

Referring to FIG. 6B, a third message 253 in the form of a voice message including voice data of a user may be received from the electronic device. The authentication unit 182 can analyze the voice data using at least one of the frequency of the voice data, the shape of the wave, and the amplitude. The authentication unit 182 can determine whether the speaker of the received voice data is a user and determine whether to perform user authentication according to the analysis result.

6B, when the first message 251 in the form of a voice message including the first voice data (for example, "High Optimus") is received from the electronic device, 182 may analyze the first voice data and may determine whether to perform user authentication immediately. That is, when a message including voice data is received from the electronic device, the authentication unit 182 can perform the user authentication immediately by analyzing the voice data, omitting the subsequent user authentication process.

FIG. 7 is a flowchart for explaining an embodiment in which user authentication of an electronic device fails consecutively. The mobile terminal 100 (see FIG. 1) includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1) and a display unit 151.

Referring to FIG. 7, step S310 is performed in which it is determined whether user authentication has failed. If the user authentication is successful, user authentication can be performed (S320). On the other hand, if the user authentication fails, it is determined whether the user authentication has failed consecutively for a predetermined number of times (e.g., "3 times") (S330).

If the user authentication fails but fails below the preset number of times, the authentication unit 182 may increase the number of failures by one. At the same time, the authentication unit 182 can wait for the authentication information to be received (S340). For example, if the second text data included in the third message 254 received from the electronic device does not correspond to a password, the authentication unit 182 can wait for a new message including a password to be received.

However, if the user authentication has failed consecutively a predetermined number of times (for example, "3 times"), the authentication unit 182 may provide a password to the user (S350). Here, the provided password may be a predetermined password or a new one-time password (OTP).

Thereafter, it is determined whether the user authentication using the password provided to the user by the authentication unit 182 has failed (S360). If the user authentication is successful, user authentication can be performed (S320). On the other hand, when the user authentication fails, that is, when the user authentication is successively failed one more time (for example, "4 times") than the predetermined number, the authentication unit 182 transmits the identification information of the electronic device (S370). Here, the identification information of the electronic device may include at least one of contact information of the electronic device and IMEI information unique to the electronic device.

IMEI means an identification number assigned to a mobile terminal so that mobile terminals can identify each other in a global system for mobile communications (GSM). The IMEI shall consist of 15 digits including the type approval code, final combination code and serial number.

The number of failures of the user authentication for proceeding with the steps S310 to S370 described in FIG. 7 may be set by the user or may be set within the mobile terminal 100. FIG. In addition, depending on the type of the electronic device, the number of failures of the user authentication to proceed the steps S310 to S370 may be changed.

8 and 9 are conceptual diagrams showing a user interface of the mobile terminal 100 when user authentication of the electronic device continuously fails. The mobile terminal 100 includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1), and a display unit 151.

FIG. 8 shows a step S320 of waiting for the authentication information to be received among the steps S320 through S340 described in FIG. 7 and a step S330 in which a password is provided to the user.

8A, when a first message 251 including first text data (e.g., "High Optimus") is received from an electronic device, the authentication unit 182 transmits a first message (251) as a message preceding the user authentication. That is, the authentication unit 182 may determine a message received from the electronic device as an encryption message for user authentication.

Next, the wireless communication unit 110 may transmit the second message 252 requesting the authentication information to the electronic device.

Thereafter, when a third message 253 including second text data (for example, "123abc") used as a cipher from the electronic device is received, the authentication unit 182 determines that the second text data corresponds to the cipher .

If the second text data does not correspond to the password, the wireless communication unit 110 may transmit the fourth message 254 indicating that the password is wrong to the electronic device. At this time, as shown, the fourth message 254 may include a wrong number of passwords (e.g., "one time").

Next, referring to FIG. 8B, a fifth message 255 including second text data (for example, "abcabc") may be received from the electronic device. If the second text data included in the fifth message 255 does not correspond to the password, the wireless communication unit 110 may transmit the sixth message 256 indicating that the password is incorrect to the electronic device.

8 (c), a seventh message 257 including second text data (e.g., "123123") may be received from the electronic device. If the second text data included in the seventh message 257 does not correspond to a password, the authentication unit 182 generates a temporary password and transmits the temporary password to the pre-designated e-mail address.

In addition, the wireless communication unit 110 may transmit an eighth message 258 indicating that the temporary password has been transmitted to the designated e-mail address to the electronic device.

FIG. 9 shows a step S340 in which identification information of the electronic device among the steps S320 to S340 described in FIG. 7 is added to the black list.

Referring to FIG. 9A, the wireless communication unit 110 may transmit the temporary password to the pre-designated e-mail address. 9 (b), a seventh message 257 containing second text data (e.g., "123123") may be received from the electronic device. If the second text data included in the seventh message 257 does not correspond to the password, the authentication unit 182 may transmit the temporary password to the previously designated e-mail address. Also, the wireless communication unit 110 may transmit an eighth message 258 indicating that the temporary password has been transmitted to the designated e-mail address to the electronic device.

Next, referring to FIG. 9B, a ninth message 259 including second text data (for example, "123cdf") may be received from the electronic device. If the second text data included in the ninth message 259 does not correspond to the password, the authentication unit 182 may add the identification information of the electronic device to the black list. As described above, the identification information of the electronic device may include at least one of contact information of the electronic device and IMEI information unique to the electronic device.

If the identification information of the electronic device is added to the blacklist, the message to be received from the electronic device can be filtered. For example, a message to be received from the electronic device may be recognized as a general message, and a message to be received from the electronic device may be blocked.

10 is a flowchart for explaining an embodiment of receiving a control command from an electronic device. The mobile terminal 100 (see FIG. 1) includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1) and a display unit 151.

Referring to FIG. 10, in operation S410, a control command included in a received message is extracted using a natural language processing algorithm.

Although not shown in the figure, at least one of the following embodiments for initiating the natural language processing algorithm may proceed prior to step S410 in which the control command included in the received message is extracted.

A text message including text data may be received from the electronic device after user authentication of the electronic device is performed. When a text message is received, the Natural Language Processing (NLP) algorithm may be initiated so that the control commands contained in the text data are extracted.

On the other hand, a voice message including voice data may be received from the electronic device. When voice data is received from the electronic device, the control unit 180 may convert voice data to text data to perform a natural language processing algorithm. Thereafter, the control unit 180 may start the natural language processing algorithm so that the control command converted into the text data is extracted.

For example, after a call signal is received from an electronic device, voice data received from the electronic device in the voice mailbox may be stored. When the voice data is stored, the control unit 180 may convert the stored voice data into text data, and may start the natural language processing algorithm so that the control command converted into the text data is extracted.

In this way, the control unit 180 can receive a message including a control command from the electronic device, and the control command can be received in a natural language form. When the message is received, the control command included in the message can be extracted through the natural language processing algorithm. Meanwhile, the control command may be received in the form of a recognizable language immediately by the control unit 180. [

Next, based on the control command, a step of performing a control operation (S420) and a step of transmitting a message informing the result of performing the control operation to the electronic device (S430) are proceeded.

Specifically, when the control command is extracted through the natural language processing algorithm, the control unit 180 can perform a control operation based on the extracted control command.

For example, the control unit 180 detects at least one of the information related to the generated event and the information stored in the memory 160 (see FIG. 1) based on the control command, Can be transmitted to the device.

Here, the detected information includes at least one of position information of the mobile terminal 100, contact information stored in the memory 160, schedule information stored in the memory 160, message information received from the other party, and call history information .

Meanwhile, although not shown, the control unit 180 may not transmit or transmit a message including information selectively detected according to the user's setting to the electronic device even if the control command is received. For example, if the user does not provide call detail information to the electronic device, the control unit 180 may not transmit the call detail information to the electronic device even if the electronic device requests the call detail information.

11 to 13 are conceptual diagrams showing a user interface of the mobile terminal 100 when receiving a control command from the electronic device. The mobile terminal 100 includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1), and a display unit 151.

11, the control unit 180 detects at least one of the information related to the generated event and the information stored in the memory 160 (see FIG. 1) based on the control command, and transmits a message containing the detected information To the electronic device.

For example, referring to FIG. 11A, a first message 261 requesting location information of the main body of the mobile terminal 100 may be received from the electronic device. As shown, the first message 261 may be composed of natural language such as "Where is it? &Quot;. The control unit 180 can recognize that the electronic device requests location information of the main body using the natural language processing algorithm.

The control unit 180 can acquire position information of the main body using the wireless communication unit 110 according to the recognition result. Then, the wireless communication unit 110 may transmit the second message 262 including the acquired location information to the electronic device.

11 (b), when a first message 261 requesting contact information of any other party (for example, "TOM") is received from the electronic device, The contact information of "TOM" Then, the wireless communication unit 110 may transmit the second message 262 including the found contact information to the electronic device.

11 (c), when a first message 261 requesting predetermined information (for example, "schedule information on October 21") is received from the electronic device, Can retrieve the schedule information of "October 21" from the memory 160. [ Thereafter, the wireless communication unit 110 may transmit the second message 262 including the retrieved schedule information to the electronic device.

11D, when the first message 261 requesting the absence call history is received from the electronic device, the control unit 180 can retrieve the absence call history from the memory 160 . Thereafter, the wireless communication unit 110 may transmit the second message 262 including the retrieved missed call details to the electronic device.

12A, when the first message 261 requesting the content of the unacknowledged received text message is received from the electronic device, the controller 180 receives the unconfigured received text message from the memory 160 And the wireless communication unit 110 may transmit the second message 262 including the detected text message to the electronic device.

A user using the electronic device can transmit a control command to the mobile terminal 100. [ For example, referring to FIG. 12 (b), a user of the electronic device transmits a text message including "Sounds Good!" To the mobile terminal 100 A control command can be transmitted.

12 (c), the control unit 180 of the mobile terminal 100 transmits a message "Sounds Good" to the "ANN" based on the control command included in the third message 263 received from the electronic device. ! &Quot;. < / RTI >

Meanwhile, the control unit 180 may display a message window indicating the message transmission result or the message confirmation result according to the control command received from the electronic device to be distinguished from other message windows.

For example, as shown in FIG. 12C, a message window 273 indicating a message that the user has confirmed through the electronic device among a plurality of message windows 271 to 274, Objects 273 'and 274' may be displayed in a message window 274 indicating the message that has been transmitted.

Accordingly, the user can intuitively grasp the execution result of the control operation according to the control command of the electronic device through the mobile terminal 100. [

On the other hand, referring to FIG. 13, the control unit 180 may install a new application or change the user interface of the home screen based on the control command.

13 (a), when a first message 261 requesting to install an application (e.g., a "TALK" application) from an electronic device and place it on the home screen is received, The control unit 180 can access the network or the server and download the "TALK" application, as shown in (b) of FIG.

13 (c), the control unit 180 may place the downloaded "TALK" application on the home screen.

Then, the control unit 180 can acquire a captured image of the home screen. As shown in FIG. 13 (d), the wireless communication unit 110 can transmit a second message 262 including a captured image of the home screen to the electronic device.

FIGS. 14 and 15 are conceptual diagrams showing a user interface when a record of performing a control operation according to a control command received from an electronic device is displayed on the mobile terminal 100. FIG. The mobile terminal 100 includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1), and a display unit 151.

Referring to FIG. 14, the control unit 180 may display on the display unit 151 notification information indicating that there is a history of user authentication performed by the electronic device, that is, notification information indicating that there is a remote connection record.

For example, as shown in FIGS. 14A and 14B, when a touch input is sensed on the display unit 151, the controller 180 may display an indicator bar on the display unit 151. FIG. The indicator bar may include notification information. Here, the notification information may include at least one of notification information indicating that software update is possible and notification information indicating that there is a remote connection record.

On the other hand, among the notification information included in the indicator bar, the icon 283 corresponding to the function for changing the setting for remote connection can be displayed together with the notification information 282 indicating that there is a remote connection record.

At this time, when the icon 283 is selected, as shown in FIG. 14C, a setting screen for receiving condition information and setting information for remote connection with the electronic device is displayed on the display unit 151 Can be displayed. The user can set at least one of whether to use the IA remote information service, the IA connection password, the password reception method when the password is wrong, and the IA remote connection holding time on the setting screen.

Referring to FIG. 15, the control unit 180 may display records of performing control operations by the electronic device on the display unit 151. FIG.

15 (a) and 15 (b), when the notification information 282 indicating that there is a remote connection record is selected from the indicator bar displayed on the display unit 151, The controller 151 may display the execution records of the control operation on the display unit 151. [

The record of the execution of the control operation may include at least one of the type of the control operation, the execution time of the control operation, and the identification information of the electronic device instructing to perform the control operation.

When one of the records 284 of the control operations displayed on the display unit 151 is selected, as shown in (c) of FIG. 15, the controller 180 displays information related to the selected control operation, (151).

For example, when the text message confirmation and transmission record 284 of the records of the control operation are selected, the control unit 180 displays a message window 273 indicating a message that the user has confirmed via the electronic device, A message window 274 indicating a message that has been transmitted using the device can be displayed on the display unit 151.

Meanwhile, as shown in the figure, a plurality of message windows 271 to 274 may be displayed on the display unit 151. At this time, a message window 273 indicating a message that the user has confirmed via the electronic device and a message window 274 indicating the message that the user has transmitted using the electronic device are distinguished from other message windows 271 and 272, (273 ', 274') may be displayed.

16 is a flowchart for explaining an embodiment in which a remote connection with an electronic device is terminated. The mobile terminal 100 (see FIG. 1) includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1) and a display unit 151.

Referring to FIG. 16, in operation S510, it is determined whether or not the third text data is included in the message.

Here, the third text data means predetermined text data for terminating the remote connection with the electronic device. The control unit 180 may determine whether the third text data is included in the message received from the electronic device.

If the received message includes the third text data, the control unit 180 may terminate the remote connection with the electronic device (S520). That is, the control unit 180 can ignore the control command received from the electronic device until new user authentication of the electronic device is performed. Then, the control unit 180 may determine a message received from the electronic device as a general message.

On the other hand, if the received message does not include the third text data, the control unit 180 may perform the control operation based on the control command included in the message received from the electronic apparatus (S530).

17 is a conceptual diagram showing a user interface of the mobile terminal 100 when the remote connection with the electronic device is terminated. The mobile terminal 100 includes a wireless communication unit 110 (see FIG. 1), an authentication unit 182 (see FIG. 1), a control unit 180 (see FIG. 1), and a display unit 151.

17A, when a first message 291 including third text data (for example, "bi-optimus") is received from an electronic device, the control unit 180 transmits a first message 291) as a message for terminating the remote connection with the electronic device. That is, the control unit 180 may determine a message received from the electronic device as a general message.

Next, the wireless communication unit 110 may transmit a second message 292 indicating that the remote connection is terminated to the electronic device. This step may be omitted.

Referring to FIG. 17B, the controller 180 may terminate the remote connection with the electronic device after a predetermined time elapses even if the controller 180 does not receive the message including the third text data from the electronic device. That is, the control unit 180 can ignore the control command received from the electronic device until new user authentication of the electronic device is performed.

Specifically, the control unit 180 may terminate the remote connection with the electronic device after a predetermined time elapses after performing the user authentication with the electronic device, or after a predetermined time elapses after receiving the last message from the electronic device The remote connection with the electronic device may be terminated.

At this time, since the wireless communication unit 110 has passed the predetermined time, the second message 292 informing that the remote connection is terminated can be transmitted to the electronic device. This step may be omitted.

Also, although not shown, the wireless communication unit 110 may be configured to wait for a preset time (for example, "1 minute before") based on the end time of the remote connection, "After 1 minute"), a message indicating that the remote connection is to be terminated may be transmitted to the electronic device.

Further, according to the embodiment disclosed herein, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
