In the functional aspect, the first operation unit 130-1 is for inputting a command such as start, end, scroll, etc., and the second operation unit 130-2 is for inputting numbers, letters, symbols, and the like. will be.

In addition, the third operation unit 130-3 may operate as a hot-key for activating a special function in the mobile terminal.

The microphone module 122 may be implemented in a form suitable for receiving a user's voice, other sounds, and the like.

The interface unit 170 serves as a passage for allowing the portable terminal according to the present invention to exchange data with an external device. For example, the interface unit 170 is wired or wirelessly, a connection terminal for connecting with an earphone, a port for short-range communication (for example, an infrared port (IrDA port), a Bluetooth port, a wireless LAN port) (wireless Lan port) etc.}, or at least one of power supply terminals for supplying power to each of the components.

The interface unit 170 may be a card socket that accommodates an external card such as a subscriber identification module (SIM) or a user identity module (UIM), a universal IC card (UICC), a memory card for storing information.

On the side of the second rear case 100B-2, a power supply unit 190 for supplying power to the (portable terminal) is mounted.

The power supply unit 190 may be detachably coupled for charging, for example, as a rechargeable battery.

3 is a rear perspective view of the portable terminal shown in FIG.

Referring to FIG. 3, a second camera module 121-2 may be additionally mounted on the rear surface of the second rear case 100B-2 of the second body 100B. The second camera module 121-2 may have a photographing direction substantially opposite to that of the first camera module 121-1 (see FIG. 1), and may have different pixels from the first camera module.

For example, the first camera module 121-1 has a low pixel so that the user's face is photographed and transmitted to the counterpart in case of a video call, and the second camera module 121-2 is a general subject. It is preferable to have a high pixel because it is not often photographed and transmitted immediately.

The flash 121-3 and the mirror 121-4 may be further disposed adjacent to the second camera module 121-2. The flash 121-3 illuminates the light toward the subject when the subject is photographed by the second camera module 121-2. The mirror 121-4 allows the user to see his / her own face or the like when the user wants to photograph himself (self photographing) using the second camera module 121-2.

The second sound output module 152-2 may be further disposed on the second rear case 100B-2.

The second sound output module 152-2 may implement a stereo function together with the first sound output module 152-1 (see FIG. 2), and may be used for a call in a speakerphone mode.

In addition, an antenna 111-1 for receiving a broadcast signal may be disposed on one side of the second rear case 100B-2 in addition to an antenna for a call. The antenna 111-1 may be installed to be pulled out of the second body 100B and 2.

A portion of the slide module 100C for slidably coupling the first body 100A and the second body 100B to the first rear case 100A-2 side of the first body 100A is disposed.

The other part of the slide module 100C may be disposed on the side of the second front case 100B-1 of the second body 100B and may not be exposed to the outside as shown in the drawing.

In the above description, the second camera module 121-2) and the like are disposed on the second body 100B, but are not necessarily limited thereto.

For example, at least one of the elements 111-1, 121-2 to 121-3, and 152-2 described as disposed on the second rear case 100B-2, such as the second camera module 121-2. It is also possible for one or more to be mounted on the first body 100A, mainly the first rear case 100A-2. In such a case, there is an advantage that the configuration (s) disposed in the first rear case 100A-2 in the closed state are protected by the second body 100B. Furthermore, even if the second camera module 121-2 is not separately provided, the first camera module 121-1 is formed to be rotatable so that shooting can be performed up to the shooting direction of the second camera module 121-2. May be

Figure 4 is an exemplary view for explaining in more detail the function related to the present invention.

Recently, many external devices or applications have attempted to use functions of the mobile terminal (eg, the Internet, wireless communication, display, sound input / output, etc.) by interacting with the mobile terminal to expand their functions.

The present invention is to support to perform the above functions more smoothly, and to improve the security when using the function to interact with the terminal as described above.

4A to 4B, the remote control module 200 of the present invention may communicate with a plurality of external devices or applications 300A to 300N in a wired or wireless manner. In addition, the remote control module may output data or a signal transmitted / received with the external device or the application 300A to 300N to the portable terminal, or interpret the signal to control a specific function of the portable terminal.

In this case, the external devices or applications 300A to 300N capable of controlling the portable terminal may be limited to devices that are authenticated or registered for security. The method will be described with reference to other drawings below.

Here, the external devices or applications 300A to 300N may operate independently as illustrated in FIG. 5, and may transmit and receive necessary information through interaction with the mobile terminal 100.

For example, when the signal transmitted from the external device is a switch on / off signal of the mobile terminal 100, the remote control module 200 generates a power control signal, according to the power circuit configuration of the mobile terminal, By applying the power control signal to the controller 180 or the power supply unit 190, the portable terminal can be switched on to communicate with the portable terminal and an external device to transmit and receive necessary information, and can switch off the portable terminal again.

In addition, the remote control module 200 may be configured inside the portable terminal as shown in FIG. 4A or may be configured to be connected to the outside through a specific port of the portable terminal as shown in FIG. 4B.

In this case, the remote control module 200 may be included in the existing interface unit 170 or may extend the function of the interface unit 170. If the remote control module 200 is configured inside the portable terminal, the form may be a Universal IC Card (UICC) type, a chip type, or a combination of several electronic components. It can also be configured in the form of a non-contact module.

In addition, the remote control module 200 may have its own power supply 210 or may use the power supply 190 of the portable terminal. The power supply unit 210 may be a power source generated by electromagnetic fields or a battery source.

In addition, the remote control module 200 may include a storage unit 220 on its own or may use the storage unit 160 of the portable terminal, and may include a separate controller 230 on its own or the controller 180 of the portable terminal. ) Can be used.

Hereinafter, for convenience of description, the operation thereof will be described using components separately provided in the remote control module 200.

Meanwhile, as illustrated in FIG. 6A, the storage unit 220 includes function information of a mobile terminal that can be remotely controlled from an external device, and information about external devices that can control each function in a table or list form. Can be stored. Of course, each external device must also store information on the remote controllable mobile terminal and information on functions that can be controlled by the mobile terminal.

The information stored in the storage unit 220 may be used as information for later authentication. The method will be described below with reference to other drawings.

In addition, the remote control module 200 may include a wired / wireless communication module 240 on its own or may selectively drive some modules of the wireless communication unit 110 of the portable terminal.

Accordingly, the external device or the application 300A to 300N may switch on / off the mobile terminal 100 through the remote control module 200 or may activate / deactivate a specific function while the mobile terminal is switched on. The action can be performed.

However, if an unauthorized external device or application controls the portable terminal, there is a risk that security is weakened.

Therefore, hereinafter, an authentication method for an external device for remote control of the mobile terminal and a method for allowing a user to recognize an external device for requesting remote control will be described in detail with reference to the accompanying drawings.

7 is a flowchart illustrating an authentication process for an external device for requesting remote control of a mobile terminal according to the present invention.

As shown in FIG. 7, when the external device wants to remotely control the mobile terminal through the remote control module 200 (S101), the controller 230 of the remote control module 200 performs a remote control (or connection). The authentication process for the requesting external device is performed (S102).

The authentication method firstly receives a personal identification number (PIN) from an external device. That is, a password is required for an external device requesting remote control.

The password may be directly input by the user of the external device through an input device provided in the external device, or may be automatically input from the external device by storing the password in the external device.

The second is to check if it is a paired external device. That is, check whether the external device requesting the remote control is already a paired device.

The pairing is to register the information of the external device requesting the remote control to the remote control module 200. When the first connection for pairing registration is received, a password is input from the external device, but when the password authentication is completed, the external device is paired. Let's do it. Once pairing is completed, the password input process may be omitted when it is confirmed that the external device requesting remote control is a paired device.

Third, information about a specific external device allowed to perform remote control registered in the storage unit of the remote control module 200 or the mobile terminal 100 and remote control registered in the external device may be performed. There is a comparison of information for each mobile terminal.

In more detail, as described above, the storage unit 220 includes information on external devices capable of remotely controlling the mobile terminal and information on respective functions allowed to be controlled by the external device. As shown in Fig. 6A, they are stored in a table or list form.

Of course, the external device may include information on a mobile terminal (eg, IMEI: International Mobile Equipment Identity) that can be remotely controlled by the external device and a function that is allowed to be controlled by a specific external device among various functions of the mobile terminal. The information should be stored in the form of a table or list as shown in FIG. 6B.

Therefore, the controller 230 of the remote control module 200 compares each table or list with each other and authenticates the external device capable of performing remote control when the information is not different.

The above-described three methods of authenticating external devices can be independently performed, and security can be improved by selectively combining the three authentication methods as necessary.

After the authentication process for the external device requesting the remote control is completed as described above, when the external device is an authenticated device (S103), the controller 230 interprets the control signal (or command) transmitted from the external device ( S104).

For example, when the portable terminal is switched off, the external device will send a switch on control signal to the remote control module. Alternatively, when the portable terminal is switched on, the external device will transmit a control signal for activating a specific function of the portable terminal to the remote control module. Alternatively, after activating and interacting with a specific function of the portable terminal, the specific function is deactivated or a control signal for switching off the portable terminal is transmitted to the remote control module. Of course, it is obvious that necessary data may be transmitted together with the control signal.

The controller 230 interpreting the control signal for the various functions as described above, referring to the list or table information shown in FIG. 6A, checks whether the function requested for the remote control by the external device is a function allowed for the external device. (S105).

According to the check result, when the control function requested by the external device is a function allowed to the external device, the controller 230 controls the portable terminal 100 to perform the function requested by the external device (S106). When the requested function is normally performed, the controller 230 may transmit a response message accordingly.

However, the first device requesting the remote control is not an authorized device, or the second request control for a function for which remote control is not allowed, or third, the device is authorized even if the external device is authenticated. Even if the remote control is requested to control the allowed function, if the state of the portable terminal is not able to perform the function normally (for example, if the battery level is too weak), an error operation is performed (S107).

The error operation outputs an error message together with a warning, and the warning may be set to be selectively outputted as shown in FIG. 6A even when normal operation as well as an error is possible.

For example, by outputting an alert whenever a remote control is requested from an external device, or outputting an alert when a function of the requested remote control is performed, the portable terminal indicates that the remote control is requested or the requested function is being performed. To users. In this case, the error operation also includes an operation of transmitting an error message to an external device.

Hereinafter, an example to which the present invention can be applied will be described with reference to the accompanying drawings of FIG. 8.

For example, the user 400 carries a portable terminal 600 having a remote control module operating in a non-contact manner, and uses an external device (terminal for payment, 500) to pay a fee using the portable terminal. Suppose you are standing in front of. In addition, it is assumed that the mobile terminal is capable of phone banking, mobile e-purse, and mobile credit card payment through the Internet.

Therefore, when the user requests a payment after inputting a fee to operate by paying the external device, the external device may pay the fee through interaction with the user's portable terminal.

That is, when the user 400 selects payment through the mobile terminal 600 (S201), the external device 500 checks whether the user terminal can interact with the mobile terminal. However, when the mobile terminal is switched off, the external device remotely switches on the mobile terminal through the remote control module 200 for interaction with the mobile terminal, and then performs a phone banking or mobile credit card function. After activation (S202), a bill payment request is made (S203).

In this case, the remote control module 200 of the portable terminal generates power by itself using an electromagnetic field radiated from an external device, even though the remote control module 200 does not receive power from the portable terminal. Activate the function (S204).

Accordingly, the portable terminal requests the external device for a password for performing a phone banking or mobile credit card function through the remote control module 200 (S205). The external device may output the password request message through its display means (S206). Accordingly, the user inputs the password through the input means provided in the external device (S207). The password is transmitted to the mobile terminal (S208), so that user authentication is completed (S209), and accordingly, the payment fee requested by the external device can be paid through a phone banking or mobile credit card function (S210).

9 is an exemplary view for explaining another example to which the present invention can be applied.

Referring to FIG. 9, it is assumed that a user 400 is driving a vehicle equipped with a Global Positioning System (GPS) device 500 capable of a general packet radio service (GPRS) function. In addition, it is assumed that the user's portable terminal 600 is switched off. The GPS device 500 receives a user's traffic information guide request (S301), determines a current location by GPS (S302), and accesses the traffic information server 700 to obtain traffic information about the location. Attempt to connect to the mobile terminal 600.

However, when the portable terminal 600 is switched off, the GPS device 500 remotely switches on the portable terminal 600 through the remote control module 200 (S303), and then the traffic of the portable terminal. By performing a server connection function (S304), access to the traffic server 700 through the Internet or a communication function (S305). The mobile terminal 600 receives the traffic information from the traffic server 700 (S306) and transmits the traffic information to the GPS device 500 (S307). After receiving the traffic information, the GPS device 500 switches off the portable terminal 600 again (S308), and outputs traffic information about the current location (S309).
