A typical example of the location information module is a GPS (Global Position System) module. According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to obtain a three-dimensional string of latitude, longitude, The location information can be accurately calculated. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time.

An audio / video (A / V) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame such as a still image or a moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display module 151.

The image frame processed by the camera 121 may be stored in the memory unit 160 or may be transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output.

For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like.

The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, you can connect a device with a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a device with an identification module, an audio I / , A video I / O (input / output) port, an earphone port, and the like.

Here, the identification module is a chip that stores various information for authenticating the use right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) ), A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port. The interface unit 170 receives data from an external device or receives power from the external device to transfer the data to each component in the mobile terminal 100 or to transmit data in the mobile terminal 100 to an external device.

In addition, when the mobile terminal 100 is connected to an external cradle, the interface unit may be a path through which power from the cradle is supplied to the mobile terminal 100, May be a pathway to the mobile terminal.

If the mobile terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

Meanwhile, as described above, when the display module 151 and the touch pad have a mutual layer structure to constitute a touch screen, the display module 151 can be used as an input device in addition to the output device. The display module 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display). Some of these displays can be configured to be transparent so that they can be viewed from outside. This may be referred to as a transparent display. A typical example of the transparent display is a transparent LCD or the like. In addition, there may be two or more display modules 151 according to the embodiment of the mobile terminal 100. For example, the mobile terminal 100 may be provided with an external display module (not shown) and an internal display module (not shown) at the same time. The touch screen may be configured to detect not only the touch input position and area but also the touch input pressure.

Although not shown in the drawings, proximity sensors may be disposed inside or near the touch screen. Or a proximity touch may be disposed within the sensing unit 140. [ The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays. Therefore, the proximity sensor has a considerably longer life than the contact-type sensor and its utilization is also quite high.

Examples of the proximity sensor 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.

Among them, the operation principle of the high-frequency oscillation type proximity sensor will be described. In the oscillation circuit, when the high frequency of the stationary wave is oscillated, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface, These changes are converted into electrical signals to detect the presence or absence of the sensing object. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

The proximity sensor may be configured so as to detect the proximity of the pointer with a change of the electric field along the proximity of the pointer, if the touch screen is electrostatic.

Accordingly, when the pointer is not actually touched on the touch screen but is located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected. Hereinafter, for the sake of convenience of description, the act of allowing the pointer to be located on the touch screen to recognize that the pointer is positioned on the touch screen is referred to as "proximity touch ", and a pointer The actual touching action will be referred to as "contact touch. &Quot; In addition, a position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor detects the proximity touch and the proximity touch pattern (for example, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, And can output information corresponding to the proximity touch operation and the proximity touch pattern on the touch screen.

[ The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, an alarm unit 153 having a vibrator can output a vibration in order to notify it. Alternatively, when the key signal is input, the alarm unit 153 can output the vibration by the feedback to the key signal input. The user can recognize the occurrence of an event through the vibration output as described above. Of course, a signal for notifying the occurrence of an event may also be output through the display module 151 or the audio output module 152. [

The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270. The BSC 275 also transmits the received data to the MSC 280 and the MSC 280 provides additional transmission services for connection with the PSTN 290. [ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as above will be described with reference to the accompanying drawings. It goes without saying that the embodiments described below can be used alone or in combination with each other.

1st Example

5 to 12, a first embodiment of a control method of a mobile terminal according to the present invention will be described.

5 to 12 are flowcharts of a first embodiment of a control method of a mobile terminal according to the present invention.

A case where a terminal user tries to remotely control the mobile terminal 100 via another external terminal 500 in a state where the terminal user does not occupy the mobile terminal 100 for a reason of losing or leaving the mobile terminal 100 do. In this embodiment, the type of the external terminal 500 is not limited as long as mobile communication with the mobile terminal 100 is possible. For example, it may be a mobile phone, a smart phone, a fixed telephone, and the like.

A terminal user makes a call to the mobile terminal 100 using the external terminal 500. That is, the external terminal 500 sends a mobile communication call setup request signal to the mobile communication module 112 of the mobile terminal 100 to attempt a mobile communication connection (S51).

Then, the controller 180 of the mobile terminal 100 determines whether the mobile communication connection attempt satisfies a predetermined condition (S52).

For example, the predetermined condition may be whether a ring-back tone is generated a predetermined number of times or longer, or whether a ring-back tone signal continues for a predetermined time or longer.

In addition, the predetermined condition may be whether or not the mobile terminal attempts to connect to the mobile terminal several times or more. The mobile terminal 100 can recognize the number of mobile communication connection attempts from the external terminal 500 by counting the number of missed calls using the caller ID of the external terminal 100, for example.

If the predetermined condition is not satisfied, the remote control procedure is terminated.

On the other hand, if the predetermined condition is satisfied, the mobile terminal 100 permits mobile communication connection with the external terminal 500 (S53).

Then, the external terminal 500 transmits predetermined identification information input to the terminal user to the mobile terminal 100 (S54). The predetermined identification information may be at least one of an ID and a password pre-set in the mobile terminal 100 by the terminal user. Even the predetermined identification information may be a public certificate for Internet banking. That is, if the mobile terminal 100 can notify the mobile terminal 100 that the terminal user has the right to use the mobile terminal 100 through the external terminal 500, the identification information is not limited.

The pad word may be more than two depending on the level (or range) at which the external terminal 500 remotely controls the mobile terminal 100. Therefore, the input identification information is hereinafter referred to as "first identification information ".

Then, the mobile terminal 100 receives the first identification information and compares the first identification information with the identification information prepared in advance in the memory unit 160 to grant the remote control right (S55). The identification information previously stored in the memory unit 160 is hereinafter referred to as "second identification information ".

When the first identification information and the second identification information are matched with each other, the mobile terminal 100 grants remote control to the external terminal 500. Since the remote control right given above needs to be distinguished according to the remote control range, it is referred to as "first remote control right ".

Then, the external terminal 500 can remotely control the mobile terminal 100 according to the first remote control right (S56).

The remote control may be performed through a mobile communication connection. A wireless Internet connection is established between the wireless Internet module 113 of the mobile terminal 100 and the external terminal 500 after the mobile terminal 100 gives the first remote control right to the external terminal 500 , And remote control may be performed through the wireless Internet connection. The mobile communication connection between the mobile terminal 100 and the external terminal 500 may be released when remote control is performed through the wireless Internet connection.

A concrete remote control scenario between the mobile terminal 100 and the external terminal 500 will be described as a separate embodiment.

On the other hand, if the first identification information and the second identification information do not match each other, the terminal user repeatedly inputs the first identification information to the external terminal 500 a predetermined number of times and transmits the first identification information to the mobile terminal 100 (S57).

If the first identification information repeatedly received for the predetermined number of times does not match the second identification information, the mobile terminal 100 informs the external terminal 500 that it can not grant the remote control right (S58 ].

Then, the mobile terminal 100 releases the connection with the external terminal 500 (S59).

5 illustrates a case where the external terminal 500 transmits predetermined identification information to the mobile terminal 100 after being once connected to the mobile terminal 100. [ However, the external terminal 500 need not be configured to transmit the predetermined identification information only after the external terminal 500 is connected to the mobile terminal 100. This will be described with reference to FIG.

A mobile communication connection is attempted by the external terminal 500 sending a mobile communication call setup request signal including the first identification information of the external terminal 500 to the mobile communication module 112 of the mobile terminal 100 [S61].

An example of the first identification information may include (but is not limited to) the calling number (Caller ID) of the external terminal 500.

Then, the mobile terminal 100 receives the first identification information and compares it with the second identification information previously stored in the memory unit 160 (S62).

As a result of the comparison, if the first identification information and the second identification information are matched, the mobile terminal 100 grants remote control while allowing connection to the external terminal 500 (S63).

However, if the first identification information and the second identification information do not match, the mobile terminal 100 rejects the connection with the external terminal 500 (S64).

Since the mobile communication connection between the mobile terminal 100 and the external terminal 500 or the remote control through the wireless Internet connection has been described above, the description thereof will be omitted.

As mentioned above, the remote control right of the external terminal 500 to the mobile terminal 100 is controlled by the first remote control right, the second remote control right, and furthermore, the remote control right . The remote control rights can be configured such that the remote control range is at least partially different from each other or the range of the second remote control right falls within the range of the second remote control right and the range of the second remote right belongs to the remote control right range .

7 is a flowchart illustrating an example of a procedure in which the external terminal 500 receives the second remote control right from the mobile terminal 100 while the mobile terminal 100 is being controlled according to the first remote control right .

The external terminal 500 is remotely controlling the mobile terminal 100 according to the first remote control right (S71).

At this time, the external terminal 500 requests the second remote control right from the mobile terminal 100 and transmits the third identification information to the mobile terminal 100 (S72).

Then, the mobile terminal 100 determines whether the received third identification information is matched with the fourth identification information prepared in advance in the memory unit 160 for granting the second remote control right (S73).

As a result of the determination, if the third identification information matches the fourth identification information, the mobile terminal 100 gives the second remote control right to the external terminal 500 (S74).

On the other hand, if the third identification information and the fourth identification information do not match, the mobile terminal 100 notifies the external terminal 500 that the second remote control right can not be granted (S75).

In FIG. 7, an example has been described in which the external terminal 500 requests the second remote control right while the mobile terminal 100 is under the first remote control right. However, the external terminal 500 can not request the second remote control right only while remotely controlling the mobile terminal 100 according to the first remote control right. This will be further described with reference to FIG.

A mobile communication connection is attempted by the external terminal 500 sending a mobile communication call setup request signal including predetermined identification information of the external terminal 500 to the mobile communication module 112 of the mobile terminal 100 [S81].

An example of the predetermined identification information may include (but is not limited to) a caller ID of the external terminal 500 or the like.

Then, the mobile terminal 100 receives the predetermined identification information and compares it with the second identification information stored in the memory unit 160 (S82).

If the predetermined identification information matches the second identification information, the mobile terminal 100 grants the first remote control right to the external terminal 500 (S83).

However, if the predetermined identification information does not match the second identification information, the mobile terminal 100 again compares the predetermined identification information with the fourth identification information previously stored in the memory unit 160 S84].

If the predetermined identification information matches the fourth identification information, the mobile terminal 100 grants the second remote control right to the external terminal 500 (S85).

However, if the predetermined identification information still does not match the fourth identification information, the mobile terminal 100 rejects the connection with the external terminal 500 (S86).

In the above description, the predetermined identification information provided from the external terminal is compared with the second identification information for the first remote control right and then compared with the fourth identification information for the second remote control right. However, the present embodiment is not limited to this, and after the predetermined identification information provided from the external terminal is compared with the fourth identification information for the second remote control right, it may be compared with the first identification information for the first remote control right Will be readily apparent to those skilled in the art.

In FIG. 8, the predetermined identification information is transmitted to the mobile terminal 100 together with the mobile communication call setup request signal. However, it is not necessary that the predetermined identification information is necessarily transmitted to the mobile terminal 100 together with the mobile communication call setup request signal. This will be described with reference to FIG.

The external terminal 500 sends a mobile communication call setup request signal to the mobile communication module 112 of the mobile terminal 100 to attempt a mobile communication connection (S91).

Then, the controller 180 of the mobile terminal 100 determines whether the mobile communication connection attempt satisfies a predetermined condition (S92). Since the predetermined conditions have already been described with reference to FIG. 5, a detailed description thereof will be omitted for the sake of simplicity of the present specification.

If the predetermined condition is not satisfied, the remote control procedure is terminated.

On the other hand, if the predetermined condition is satisfied, the mobile terminal 100 permits mobile communication connection with the external terminal 500 (S93).

Then, the external terminal 500 transmits predetermined identification information to the mobile terminal 100 (S94).

As an example of the predetermined identification information, there may be (but not limited to) a caller ID of the external terminal 500 as described above.

Then, the mobile terminal 100 receives the predetermined identification information and compares it with the second identification information stored in the memory unit 160 (S95).

As a result of the comparison, if the predetermined identification information matches the second identification information, the mobile terminal 100 gives the first remote control right to the external terminal 500 (S96).

However, if the predetermined identification information does not match the second identification information, the mobile terminal 100 again compares the predetermined identification information with the fourth identification information previously stored in the memory unit 160 S97].

If the predetermined identification information matches the fourth identification information, the mobile terminal 100 gives the second remote control right to the external terminal 500 (S85).

However, if the predetermined identification information still does not match the fourth identification information, the mobile terminal 100 informs the external terminal 500 that it can not grant the remote control right (S99).

Then, the mobile terminal 100 releases the connection with the external terminal 500 (S100).

In the above description, the external terminal 500 sends a mobile communication call setup request signal to the mobile terminal 100 to start the remote control setup procedure. However, the present embodiment is not limited to this, and the external terminal 500 may send a message (for example, SMS, MMS, e-mail, etc.) to the mobile terminal 100 to configure . This will be described with reference to FIG.

A message including the first identification information is transmitted from the external terminal 500 to the mobile terminal 100 (S101). If the message is SMS or MMS, it is transmitted through a mobile communication connection, and if the message is e-mail, it is transmitted through a wireless Internet connection. If the message is MMS or e-mail, the first identification information may be included in the body of the MMS or the e-mail, or may be included as an attachment of the first identification information.

Then, the mobile terminal 100 parses the message and extracts the first identification information (S102).

Next, the mobile terminal 100 determines whether the first identification information matches the second identification information stored in advance in the memory unit of the mobile terminal 100 (S103).

If it is determined that the first identification information matches the second identification information, the mobile terminal attempts to access the external terminal and gives a remote control right (S104). The connection to the external terminal can be performed through mobile communication or wireless Internet.

However, if it is determined that the first identification information does not match with the second identification information, the mobile terminal rejects the connection with the external terminal (S105).

As described above, when the mobile terminal 100 is being remotely controlled by the external terminal 500 according to the first remote control right or the second remote control right, the operation of the user input unit 130 of the mobile terminal 100 It may be necessary to discuss whether the remote control can be released by the user. This will be further described with reference to FIG.

The mobile terminal 100 is remotely controlled by the external terminal 500 (S111).

At this time, an occupant occupying the mobile terminal 100 attempts to release the remote control by operating the user input unit 130 (S112). The operation of the user input unit 130 for releasing the remote control may be a menu operation of the mobile terminal 100 for remote control release or a power off of the mobile terminal. The menu operation of the mobile terminal 100 for remote control cancellation may be easily understood by those skilled in the art, so a detailed description thereof will be omitted for the sake of simplicity in this specification.

Then, the control unit of the mobile terminal 100 determines whether the remote control is based on the first remote control right or the second remote control right (S113).

As a result of the determination, if the remote control is based on the first remote control right, the mobile terminal 100 releases the remote control and notifies the external terminal 500 of the release of the remote control (S114).

On the other hand, if the remote control is according to the second remote control right, the mobile terminal 100 keeps the remote control in spite of the operation of the user input unit (S115). The mobile terminal 100 may be configured to notify the external terminal 500 of an attempt to release the remote control through the operation of the user input unit 130 as needed.

The identification information may be pre-stored in the memory unit 160 of the mobile terminal 100 by the terminal user. However, in such a case, the identification information may be forgotten if the terminal user does not use the identification information for a long time, or if the identification information is exposed, . A method for solving the problem will be described with reference to FIG.

The terminal user is connected to a server (hereinafter referred to as a "mobile communication server") 600 of a mobile communication company that carries out mobile communication of the mobile terminal using the external terminal 500, (I.e., user authentication) to authenticate that the user 100 has a proper use right (S121). To this end, at least one of a resident registration number, an ID, a password, and a public certificate that can prove the identity of the terminal user can be transmitted to the mobile communication server 600 through the external terminal 500.

In step S122, the mobile communication server 600 determines whether the terminal user has a right to use the mobile terminal 100 based on the transmitted data.

As a result of the determination, if it is determined that the user does not have the right to use the service, the mobile communication server 600 informs the external terminal 500 that the user authentication has failed and the procedure is terminated (S123).

The mobile communication server 600 transmits the first identification information to the mobile terminal 100 so that the mobile terminal 100 can be stored in the memory unit 160 of the mobile terminal 100 , And transmits the second identification information to the external terminal 500 (S124, S125).

Accordingly, the terminal user can remotely control the mobile terminal 100 through the external terminal 500 according to the procedure described in FIGS. 5 to 10 using the first identification information and the second identification information (S126 ].
