As shown in the figure, the wireless communication module 110 of the mobile terminal 100 according to an embodiment of the present invention may include a plurality of modules. For example, the wireless communication module 110 may include first to third wireless communication modules 212, 214, and 216.

The first to third wireless communication modules 212, 214, and 216 may be communication modules using different communication methods. For example, the first wireless communication module 212 is a Bluetooth communication module, the second wireless communication module 214 is a Wifi direct communication module, and the third wireless communication module 216 is a Wifi communication module do.

The control unit 180 can simultaneously activate any one or a plurality of the first to third wireless communication modules 212, 214, and 216. For example, when the first wireless communication module 212 is activated and the second wireless communication module 214 is activated, or when the first wireless communication module 212 is activated, 214, 216 can be activated. Activation may mean that communication with another device through the corresponding communication module is established or can be performed. However, when MCC (Multi Channel Connect) is not supported, simultaneous activation of a plurality of communication modules may be restricted. For example, it means that only one of the second wireless communication module 214 and the third wireless communication module 216 may be selectively activated.

FIG. 5 is a flowchart illustrating an operation procedure of the mobile terminal of FIG. 1;

The control unit 180 of the mobile terminal 100 according to the embodiment of the present invention performs step S10 of forming a first communication channel using the first wireless communication module 212 can do.

The first wireless communication module 212 may be a communication module that can be used for communication between the mobile terminal 100 and another device 200. [ For example, the first wireless communication module 212 may be a Bluetooth communication module.

The mobile terminal 100 and another device 200 may form a first communication channel through the first wireless communication module 212. [ The first communication channel through the first wireless communication module 212 may be a communication channel for exchanging basic information required for operation between the mobile terminal 100 and another device 200. [ For example, information that may form the second and / or third communication channel through the second and / or third wireless communication module 214, 216 via the first communication channel.

The first communication channel formed through the first wireless communication module 212 may have a lower data exchange rate than other types of communication channels. The first communication channel may have a shorter transmission distance than other types of communication channels. However, the first communication channel may have better stability than other types of communication channels. The first communication channel may consume less power than other types of communication channels. Because of this feature, the first communication channel can be used as a communication channel capable of backing up communication channels of other types. For example, the first wireless communication module 212 is always active and can exchange basic data with another device.

The control unit 180 may proceed to step S20 of acquiring the information of the content of the other device 200 through the first communication channel.

The first communication channel may be a communication channel formed based on the first wireless communication module 212 that is commonly activated between the mobile terminal 100 and another device 200 as described above.

The control unit 180 can obtain certain information from the device 200 through the first communication channel. For example, information on the content stored in the other device 200 can be obtained.

The information of the content may not be the content itself. The information on the content may be information on the attribute of the content stored in the other device 200, for example. For example, the information of the content may be information including at least one of the existence of the content, the number of the content, the name of the content, and the size of the content.

The first communication channel may have a relatively low transmission rate. Therefore, the control unit 180 can acquire only the content information, not the content itself, through the first communication channel. Since the content information may be relatively small in capacity as compared with the content itself, it can be obtained smoothly even through the first communication channel with a slow transmission speed.

The control unit 180 can proceed to step S30 of displaying the acquired content information.

The information of the content may not be the content itself, as described above. Accordingly, the control unit 180 can display a dummy object or the like that can notify the user of the existence of the corresponding content or the like. For example, it means that a certain other device 200 can display an icon or the like that can indicate that an image file exists.

The control unit 180 may proceed to step S50 of forming a second communication channel using the second wireless communication module 214 when acquiring a signal for selecting information of the displayed content (S40).

The second wireless communication module 214 may be a communication module that uses a communication protocol different from that of the first wireless communication module 212. For example, the second wireless communication module 214 may be a Wifi direct communication module.

The control unit 180 can activate the second wireless communication module 214 of the other device 200. [ For example, this means that the second wireless communication module 214 of the other device 200 that has been turned off can be turned on. The control command for activating the second wireless communication module 214 of the other device 200 may be transmitted via the first communication channel by the first wireless communication module 212. [

The control unit 180 may proceed to step S60 of acquiring the data of the content of the other device 200 via the second communication channel.

The other device 200 may have the content itself corresponding to the information of the previously acquired content. The control unit 180 can acquire the data of the content itself held by the other device 200 through the second communication channel. For example, it means that data of a relatively large content can be acquired through a second communication channel having a relatively higher transmission rate than the first communication channel.

The control unit 180 can proceed to display the acquired content data (S70). For example, when the content is an image, the control unit 180 indicates that the acquired image can be displayed on the display 151. [

FIG. 6 is a flow chart illustrating a process of forming a second communication channel using a second wireless communication module during an operation of the mobile terminal of FIG. 5;

As shown in the figure, the step of forming the second communication channel using the second wireless communication module (S50) includes activating the second wireless communication module 214 of the other device 200 using the first communication channel (S52).

The second wireless communication module 214 of the other device 200 may be inactivated to reduce power consumption or the like. In such a case, it may be necessary to activate the second wireless communication module 214 to form the second communication channel. The command for activating the second wireless communication module 214 may be transmitted through the first communication channel formed.

The step S54 of forming a second communication channel with the second wireless communication module of the other device 200 may be performed based on the information acquired through the first communication channel.

The control unit 180 can acquire information necessary for forming another communication channel through the first communication channel. For example, an address value and the like necessary for forming the second communication channel can be obtained through the first communication channel.

The control unit 180 can form a second communication channel with another device 200 based on the information acquired through the first communication channel.

FIG. 7 is a signal flow graph illustrating signal transmission between a mobile terminal and another device.

As shown in the figure, the mobile terminal 100 according to an embodiment of the present invention can perform a specific operation by exchanging signals with another device 200. [ For example, it means that data can be exchanged through a communication channel formed using a plurality of wireless communication modules.

The first wireless communication module of the mobile terminal 100 and the first wireless communication module of the other device 200 may be activated (S2, S4). That is, the first wireless communication module of the two devices may be turned on it means.

A first communication channel may be formed between the mobile terminal 100 and another device 200 (S10). That is, it means that the first communication channel can be formed through the activated first wireless communication module.

Information for forming the second and third communication channels can be obtained (S52) from the other device 200 through the formed first communication channel.

It is possible to activate the second wireless communication module of the mobile terminal 100 in operation S54 and transmit a command for activating the second wireless communication module of the other device 200 in operation S56. 2 wireless communication module can be transmitted via the first formed communication channel.

The other device 200 that has received the second wireless communication module activation command from the mobile terminal 100 can activate the second wireless communication module (S58).

When the MCC is supported (S62), the command S64 for activating the third wireless communication module can be transmitted to the other device 200. [ The MCC is a technology capable of simultaneously activating the second and third wireless communication modules. For example, this means that it can be a technology that can simultaneously activate Wifi direct communication module and Wifi communication module.

The other device 200 that has received the command to activate the third wireless communication module may activate the third wireless communication module (S66).

The mobile terminal 100 can acquire the data of the content via the second or third communication channel (S68). The second or third communication channel may have a higher transmission rate than the first communication channel. Thus, through the second or third communication channel, transmission can be performed more quickly and conveniently.

The mobile terminal 100 can display the acquired content (S70).

The mobile terminal 100 may transmit a command S82 for deactivating the second and third wireless communication modules when the communication is terminated (S80). The other device 200 that has received the command can deactivate the second and third wireless communication modules (S84).

The termination of the communication may proceed if there is no more data to transmit using the second and third communication channels. That is, it may mean that the connection of the communication channel is intentionally terminated. In the case where the communication channel is no longer used, power consumption can be reduced by deactivating the second and third wireless communication modules.

If the connection of the communication channel is inadvertently terminated, it is possible to reacquire the information necessary for the formation of the second and / or third communication channel through the first communication channel. Unintentional termination may mean that communication is broken even though there is data to be transmitted due to a communication failure or the like. Since the second and / or third communication channels are already in a broken state, information necessary for the re-formation of the second and / or third communication channels through the second communication channel can be obtained.

8 and 9 are diagrams illustrating operations of the mobile terminal of FIG.

As shown in these drawings, the control unit 180 of the mobile terminal 100 according to an embodiment of the present invention can acquire and display necessary information through a plurality of communication channels.

8 (a), the control unit 180 of the mobile terminal 100 can display an image album on the display 151. In addition, The image album may display a first thumbnail (TN) corresponding to an image stored in the mobile terminal 100. [ That is, the first thumbnail TN may be an image corresponding to an image stored in the memory 160 of the mobile terminal 100.

The control unit 180 can display the dummy object DO.

The dummy object DO may be an icon corresponding to the information acquired through the first communication channel. For example, information of an image stored in another device 200 through the first communication channel can be obtained. That is, information on at least one of existence, number, name, and size of images acquired through the first communication channel, rather than data of the image itself, can be reflected through the dummy object (DO).

The dummy object DO can be displayed in the form of an empty folder, unlike the first thumbnail TN. That is, since the data of the image stored in the other device 200 is not received, the dummy object DO may not include the image itself. The dummy object DO can display simple information acquired through the first communication channel, for example, the number of images, the name, the size, and the like.

As shown in FIG. 8B, when the user's selection of the dummy object DO is input, the control unit 180 can display the pop-up message P. The pop-up message P may be displayed while forming the second and / or third communication channel and acquiring data of the image via the formed communication channel.

As shown in FIG. 9A, when the image stored in another device 200 is acquired, the control unit 180 can display the acquired image DI. The acquired image DI may be data obtained via the second and / or third communication channel.

9B, when there is an input of the user to return to the image gallery after displaying the acquired image DI, the control unit 180 sets the second thumbnail OI Can be displayed. The second thumbnail (OI) may be an image corresponding to an image stored in another device (200). Since the data is acquired through the second and / or third communication channels, the second thumbnail (OI) can be displayed based on the acquired data.

FIG. 10 is a diagram showing another operation of the mobile terminal of FIG. 5;

As shown in the figure, the mobile terminal 100 according to the embodiment of the present invention can continuously reproduce the content reproduced by the mobile terminal 100 in another device 200. [

As shown in FIG. 10 (a), the user can play back the moving picture content VC in the mobile terminal 100. The user can stop watching the video content VC for a certain period of time.

As shown in FIG. 10 (b), the user can use the other device 200. The thumbnail ST of the video that the user has watched on the mobile terminal 100 can be displayed on the other device 200. [ The thumbnail ST of the image can easily display what image the user has viewed on the mobile terminal 100 and to what extent. For example, it means that a thumbnail image of the point where the appreciation is ended can be displayed.

10 (c), when the thumbnail ST of the video is selected, the other device 200 can continuously reproduce the video content VC that the user has watched from the mobile terminal 100 . Therefore, the user can easily enjoy the contents on various devices.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
