1 is a block diagram showing a mobile data transfer system according to an embodiment of the present invention.

Referring to FIG. 1, a mobile data transfer system according to an embodiment of the present invention includes a transfer terminal 110, a new terminal 120, a mobile data transfer device 130, and a cloud 140.

The transfer terminal 110 may correspond to a terminal previously used by a user.

At this time, the transfer terminal 110 may generate all data stored by the user, such as a phone book, image data, music data, text messages, applications, and the like as backup data.

In this case, the transfer terminal 110 corresponds to a mobile communication terminal, and may be a mobile terminal that is connected to the mobile data transfer device 130 and provides backup data. In addition, the transfer terminal 110 may be connected to the cloud 140 via a network to provide backup data.

In addition, the display unit of the transfer terminal 110 may display information on a series of operation states and operation results generated while the transfer terminal 120 generates the backup data. Herein, the display unit of the transfer terminal 120 includes a liquid crystal display (LCD), a thin film transistor (TFT-LCD), a light emitting diode (LED), and an organic light emitting diode. It may be composed of a diode (Organic LED, OLED), an active organic light emitting diode (AMOLED), a Retina display, a flexible display and a three-dimensional display.

In addition, the storage unit of the transfer terminal 110 is a device for storing data, and includes a main memory device and an auxiliary storage device, and may store an application program required for the functional operation of the transfer terminal 110.

In addition, the communication unit of the transfer terminal 110 may perform a function for transmitting and receiving data with the mobile data transfer device 130 and the cloud 140.

For example, when the transfer terminal 110 is connected to the mobile data transfer device 130, the transfer terminal 110 may receive a message requesting backup data from the mobile data transfer device 130. In addition, the backup data generated in the transfer terminal 110 may be transferred to the mobile data transfer device 130.

As another example, when the transfer terminal 110 is connected to the cloud, the backup data may be uploaded to the cloud 140.

In addition, the control unit of the transfer terminal 110 may be a process device for driving the operating system (OS) and each component. For example, the entire process of generating backup data can be controlled. That is, the controller of the transfer terminal 110 may control the entire process of generating the backup data, and may control the transfer of the generated backup data to the mobile data transfer device 130 and the cloud 140.

The new terminal 120 may be connected to the mobile data transfer device 130 and the cloud 140 to correspond to a terminal receiving the backup data from the transfer terminal 110.

The mobile data transfer device 130 generates first channel data transferred to a first channel and second channel data transferred to a second channel by using backup data when transferring data between terminals.

In this case, the first channel data and the second channel data may be generated corresponding to the wired channel and the wireless channel, respectively.

In this case, the first channel data and the second channel data may be generated in consideration of at least one of data information, data capacity, data type, connection state of the wireless channel, and the performance of the transfer terminal that are previously stored in the cloud used in the wireless channel. have.

In this case, as the at least one of the connection state of the wireless channel and the performance of the transfer terminal is better, more second channel data may be generated.

In this case, media data having a data capacity equal to or larger than a predetermined reference capacity among the backup data may be generated as second channel data.

In this case, data corresponding to terminal data whose data type is not media data among the backup data may be generated as first channel data.

In addition, the mobile data transfer device 130 transfers the first channel data to the new terminal by using the first channel, and transfers the second channel data to the new terminal by using the second channel.

At this time, the first channel and the second channel may be shared in the transfer of the backup data.

In this case, in the case of the second channel data corresponding to the data information previously stored in the cloud, the second channel data previously stored in the cloud may be directly transferred to the new terminal without uploading the second channel data to the cloud.

In this case, when all of the second channel data is uploaded to the cloud, even if the wired channel is disconnected, the second channel data may be transferred to the new terminal based on the cloud.

At this time, when the transfer of any one channel data of the first channel data and the second channel data is completed first, a portion of the channel data that has not yet been transferred can be transferred to the channel where the transfer is completed can be transferred to the new terminal. .

The cloud 140 may be connected to the transfer terminal 110, the new terminal 120, and the mobile data transfer device 130 through a network to perform a series of operations for mobile data transfer.

For example, the mobile data stored in the transfer terminal 110 may be backed up and stored in connection with the transfer terminal 110 at any time. In addition, when data is transferred between terminals, the second channel data may be received from the transfer terminal 110 or the mobile data transfer apparatus 130 to perform data transfer to the new terminal 120.

In this case, the cloud 140 may perform an operation for efficient data transfer by sharing the transfer of backup data with the mobile data transfer device 130.

For example, when the data transfer process through the mobile data transfer device 130 is slow, more data may be transferred through the cloud 140. Alternatively, when the data transfer is slow due to poor connection of the cloud 140, more data may be transferred through the mobile data transfer device 130.

At this time, although not shown in Figure 1, the transfer terminal 110, the new terminal 120 and the mobile data transfer device 130 and the cloud 140 according to the present invention can communicate over a network.

At this time, the network is to provide a path for transferring data between the transfer terminal 110, the new terminal 120 and the mobile data transfer device 130 and the cloud 140, the network used in the future and possible future development It is a concept that encompasses all networks. For example, a network may be a wired / wireless local area network that provides communication of various information devices within a limited area, a mobile communication network that provides communication between each other and between the mobile and the outside of the mobile, and provides communication between the base station and the stations using satellites. The network may be either a satellite communication network or a wired or wireless communication network, or a combination of two or more. Meanwhile, the transmission standard of the network is not limited to the existing transmission standard, and may include all transmission standard that will be developed in the future.

2 is a flowchart illustrating a two-channel mobile data transfer method according to an embodiment of the present invention.

Referring to FIG. 2, in the 2-channel mobile data transfer method according to an embodiment of the present invention, when data is transferred between terminals, the first channel data and the second channel are transferred to the first channel using backup data. The second channel data is generated (S210).

In this case, the first channel data and the second channel data may be generated in at least one of a separate mobile data transfer device or a transfer terminal for mobile data transfer according to the configuration of the system.

For example, when the mobile data transfer device generates the mobile data transfer device, the mobile data transfer device may obtain backup data from the transfer terminal and generate first channel data and second channel data using the backup data. At this time, the transfer terminal may be connected to the mobile data transfer device by wire to transfer the backup data.

For another example, when the transfer terminal generates, when the transfer terminal is connected to the mobile data transfer device and is requested to generate the first channel data, the transfer terminal may generate the first channel data and the second channel data using the backup data. have.

In this case, the first channel data and the second channel data may be generated corresponding to the wired channel and the wireless channel, respectively.

For example, the first channel may correspond to a wired channel for directly connecting the transfer terminal and the new terminal to the mobile data transfer device for mobile data transfer. In addition, the second channel may correspond to a wireless channel through which the transfer terminal and the new terminal access the cloud for mobile data transfer through the network, respectively.

In this case, the cloud may correspond to a service in which a user may access various types of content or data by accessing the Internet through a terminal such as a laptop or a smart phone. That is, since various data can be stored freely after being stored in an external cloud server rather than in an internal storage space of a user's PC or a smart phone, contents having a large capacity can be used even in a terminal having insufficient storage space.

At this time, the transfer terminal and the new terminal may be connected to the mobile data transfer device corresponding to the wired channel using a separate jack.

In this case, the mobile data transfer device used in the wired channel is a device capable of executing mobile data transfer by being connected to a transfer terminal and a new terminal, and may correspond to a device connected to a communication network and capable of communicating with the cloud. For example, the mobile data transfer device may correspond to various terminals such as all information communication devices, multimedia terminals, wired terminals, fixed terminals, and IP (Internet Protocol) terminals. In addition, the mobile data transfer device, if the transfer terminal and the new terminal can be connected and can communicate with the cloud, mobile phones, Portable Multimedia Played (PMP), Mobile Internet Device (MID), smart phone (Smart Phone), Desktop (Desktop) Mobile with various mobile communication specifications such as tablet PC, tablet PC, note book, net book, personal digital assistant (PDA), smart TV and information communication device It may correspond to a terminal.

In this case, the first channel data and the second channel data may be generated in consideration of at least one of data information, data capacity, data type, connection state of the wireless channel, and the performance of the transfer terminal that are previously stored in the cloud used in the wireless channel. have.

In this case, the data information previously stored in the cloud may correspond to the mobile data information that the user backs up to the cloud at any time while using the transfer terminal. Accordingly, when data already stored in the cloud among the backup data of the transfer terminal exists, the corresponding data may be generated as the second channel data so that the transfer data can be transferred to the new terminal through the cloud.

In this case, as the at least one of the connection state of the wireless channel and the performance of the transfer terminal is better, more second channel data may be generated.

For example, it may be assumed that half of the backup data of the transfer terminal is generated as the first channel data and the other half is generated as the second channel data. At this time, if the connection state of the wireless channel is good and the speed at which the second channel data is uploaded from the transfer terminal and the rate at which the second channel data is transferred from the cloud to the new terminal is very fast, even if data of the same capacity is transferred, Transferring data using a channel may be more effective.

Therefore, before generating the first channel data and the second channel data, it is possible to determine how much to generate the second channel data by identifying the connection state of the wireless channel and the performance of the transfer terminal in advance.

For example, the data generation rate for each grade of the connection state of the wireless channel and the performance of the transfer terminal may be set in advance, and the first channel data and the second channel data may be generated at the data generation rate according to the corresponding grade. That is, when the connection status of the wireless channel and the performance of the transfer terminal are 1 grade, the first channel data and the second channel data may be generated at a ratio of 3 to 7. In addition, when the connection state of the wireless channel and the performance of the transfer terminal is a second level, the first channel data and the second channel data may be generated at a ratio of 4 to 6. In addition, when the connection state of the wireless channel and the performance of the transfer terminal is a grade 3 level, the first channel data and the second channel data may be generated at a ratio of 5 to 5. In addition, when the connection status of the wireless channel and the performance of the transfer terminal is a grade 4, the first channel data and the second channel data may be generated at a ratio of 6 to 4. In addition, when the connection state of the wireless channel and the performance of the transfer terminal is a grade 5, the first channel data and the second channel data may be generated in a ratio of 7 to 3.

At this time, the data generation rate is only one example according to the connection state of the wireless channel and the performance of the transfer terminal, and the second channel data according to the connection state of the wireless channel and the performance of the transfer terminal by applying various methods. Can be generated.

In this case, media data having a data capacity equal to or larger than a predetermined reference capacity among the backup data may be generated as second channel data.

For example, when the preset reference capacity corresponds to 1 GB, media data having a data capacity of 1 GB or more may be generated as second channel data.

In this case, the media data may be data including an image, a photo, a video, etc. except the terminal data.

In this case, data corresponding to terminal data whose data type is not media data among the backup data may be generated as first channel data. That is, the terminal data having a relatively high importance among the backup data may be generated as the first channel data so that data transfer may be performed through a wired channel having a relatively stable transfer environment than the wireless channel.

In this case, the terminal data may be generated as the first channel data for stable data transfer even if the data capacity is large.

In this case, the terminal data may correspond to data of high importance, such as an address book, text data, personal certificate, and the like. In this case, the terminal data may be designated by the user directly selecting an item to be included as the terminal data.

In this case, only the terminal data and the media data are described above, but various types of data may be set according to the setting.

In addition, for each of various data types, whether the first channel data is generated or the second channel data may be specified in advance.

In addition, the remaining data except for the terminal data may be generated by classifying the first channel data and the second channel data according to other conditions except for the data type.

For example, if the user wishes to transfer the application data and the media data to the second channel, the application data and the media data may be generated as the second channel data regardless of other conditions.

In this case, the application data may include both data related to the installation of the application installed in the transfer terminal and data stored by the user.

In addition, the two-channel mobile data transfer method according to an embodiment of the present invention transfers the first channel data to the new terminal using the first channel, and transfers the second channel data to the new terminal using the second channel. Transfer (S220). That is, the first channel data may be transferred to the new terminal through the first channel through the mobile data transfer device, that is, the wired channel. In addition, the second channel data may be transferred to a new terminal through a second channel through the cloud, that is, a wireless channel.

At this time, the first channel and the second channel may be shared in the transfer of the backup data. For example, the mobile data transfer device used for the first channel and the cloud used for the second channel share a process and information for transferring the backup data to each other so that efficient transfer can be performed according to the transfer situation.

For example, the shared information may include information of backup data classified as first channel data, information of backup data classified as second channel data, data transfer rate through a first channel, data transfer situation through a first channel, The data transfer rate through the second channel, the connection state of the second channel, the data transfer situation through the second channel, the cloud upload situation of the second channel data, and the like. That is, various information that may occur in the process of transferring the backup data can be shared.

In this case, in the case of the second channel data corresponding to the data information previously stored in the cloud, the second channel data previously stored in the cloud may be directly transferred to the new terminal without uploading the second channel data to the cloud. That is, the unnecessary transfer process of uploading the data information previously stored in the cloud back to the cloud in the transfer terminal or the mobile data transfer device may be omitted, thereby improving the data transfer speed in the second channel.

Therefore, the information stored in the cloud can be checked before uploading the second channel data to the cloud.

For example, a transfer terminal or a mobile data transfer device capable of uploading second channel data may be connected to a cloud to check storage information.

In this case, when all of the second channel data is uploaded to the cloud, even if the wired channel is disconnected, the second channel data may be transferred to the new terminal based on the cloud. That is, since the second channel data is transferred to the new terminal through the wireless channel, even if the data transfer in the first channel through the wired channel is completed and the connection is released, data transfer in the second channel can be continuously performed.

However, depending on whether the second channel data is uploaded to the cloud from the transfer terminal or the mobile data transfer device, the second channel is independent of disconnection of the first channel only when all of the second channel data is uploaded to the cloud. Data transfer may be performed continuously.

For example, when the second channel data is uploaded from the mobile data transfer device, after all the second channel data has been uploaded to the cloud, data transfer of the second channel is continuously performed regardless of disconnection of the first channel. Can be. If it is assumed that the first channel is disconnected while the second channel data is not uploaded from the mobile data transfer device to the cloud, the mobile data transfer device may complete the data transfer as soon as the first channel is disconnected. You can also decide to stop uploading. Therefore, in preparation for such a case, it is possible to check whether all of the second channel data has been uploaded and to disconnect the first channel.

In another example, when the second channel data is uploaded from the transfer terminal, even if the second channel data is not completely uploaded to the cloud, data transfer of the second channel may be continuously performed regardless of disconnection of the first channel. It may be. In such a case, since the second channel data uploads and transfers data without passing through the mobile data transfer device, data transfer of the second channel may be performed regardless of whether the first channel is disconnected.

In this case, the above example corresponds to one example that can be variously applied according to the mobile data transfer system, there may be various embodiments depending on the setting of the transfer terminal, the new terminal, the mobile data transfer device and the cloud.

At this time, when the transfer of any one channel data of the first channel data and the second channel data is completed first, a portion of the channel data that has not yet been transferred can be transferred to the channel where the transfer is completed can be transferred to the new terminal. .

For example, it may be assumed that data transfer by the first channel is completed but data transfer by the second channel is not yet completed. In this case, data transfer may be performed more efficiently by transferring a part of the second channel data to the mobile data transfer device and transferring the data to the new terminal.

As another example, it may be assumed that data transfer by the second channel is completed but data transfer by the first channel is not yet completed. At this time, a part of the first channel data may be transferred to the cloud and transferred to the new terminal. However, if the first channel data, which has not yet completed data transfer, corresponds to data set to be transferred only through the first channel like the terminal data, data transfer may be performed through the first channel even though it takes longer. .

In addition, although not shown in Figure 2, the two-channel mobile data transfer method according to an embodiment of the present invention can transmit and receive data necessary for the mobile data transfer through a communication network, such as a network.

In addition, although not shown in Figure 2, the two-channel mobile data transfer method according to an embodiment of the present invention can store a variety of information generated during the mobile data transfer process according to the embodiment of the present invention as described above have.

Through such a mobile data transfer method, data transfer of a mobile terminal can be performed more efficiently using two channels.

In addition, by transferring sensitive information such as user's personal information to a wireless channel instead of a transfer PC, personal information can be prevented from being leaked through the transfer PC, and information can be shared between wired and wireless channels when transferring mobile data. It may be possible to complete data transfers more quickly by transferring more data to a smoother channel.

3 to 4 are diagrams illustrating a mobile data transfer process according to channel data generation according to an embodiment of the present invention.

3 to 4, in the mobile data transfer process according to channel data generation according to an embodiment of the present invention, channel data may be generated in the mobile data transfer device 130 as shown in FIG. 3. Channel data may be generated in the transfer terminal 110 as shown in FIG.

Therefore, the backup data of the transfer terminal 110 may be transferred to the mobile data transfer device 130 through a line connected to the mobile data transfer device 130.

Thereafter, the mobile data transfer device 130 may generate first channel data to be transferred to the first channel and second channel data to be transferred to the second channel by using the received backup data.

In this case, the first channel may correspond to a wired channel capable of transferring data through the mobile data transfer device 130 wired to the transfer terminal 110 and the new terminal 120.

In addition, the second channel may correspond to a wireless channel through which the transfer terminal 110, the new terminal 120, and the mobile data transfer device 130 may transfer data through the cloud 140 connected to the network.

Therefore, the mobile data transfer device 130 may transmit the second channel data among the channel data generated through the backup data to the cloud 140.

At this time, the mobile data transfer device 130 may obtain information on the data stored in the cloud 140 in advance and may not transmit the backup data previously stored in the cloud 140 among the second channel data.

In this case, the mobile data transfer device 130 and the cloud 140 may share backup data, that is, data transfer of the first channel data and the second channel data.

For example, the information of the backup data classified as the first channel data, the information of the backup data classified as the second channel data, the data transfer rate through the first channel, the data transfer situation through the first channel, and the second channel Information such as data transfer rate, connection state of the second channel, data transfer state through the second channel, and cloud upload state of the second channel data may be shared.

Thereafter, the mobile data transfer device 130 and the cloud 140 may perform data transfer to the new terminal 120 through a wired channel and a wireless channel, respectively.

In addition, referring to FIG. 4, in the mobile data transfer process according to an embodiment of the present invention, first, the transfer terminal 110 transfers the first channel data and the second channel to be transferred to the first channel using the backup data. Second channel data may be generated.

In this case, the first channel and the second channel are the same as the channel described with reference to FIG. 3 and may correspond to the wired channel and the wireless channel, respectively.

Accordingly, the transfer terminal 110 may transfer each channel data corresponding to each channel. That is, the transfer terminal 110 may transmit the first channel data to the mobile data transfer device 130 corresponding to the first channel, and the second channel data to the cloud 140 corresponding to the second channel. .

In this case, the transfer terminal 110 may acquire information on the data stored in the cloud 140 in advance and may not transmit the backup data previously stored in the cloud 140 among the second channel data.

Thereafter, the mobile data transfer device 130 and the cloud 140 that have received the channel data may share backup data, that is, data transfer of the first channel data and the second channel data.

Thereafter, the mobile data transfer device 130 and the cloud 140 may perform data transfer to the new terminal 120 through a wired channel and a wireless channel, respectively.

5 is an operation flowchart showing in detail a mobile data transfer method according to an embodiment of the present invention.

5, the mobile data transfer method according to an embodiment of the present invention first connects the transfer terminal and the new terminal to the mobile data transfer device (S510).

At this time, the transfer terminal and the new terminal may be connected to the mobile data transfer device using a jack corresponding to each terminal.

In this case, the mobile data transfer device is used for mobile data transfer in a wired channel corresponding to the first channel, and may correspond to a device connected to a communication network and capable of communicating with the cloud.

At this time, the transfer terminal and the new terminal may be connected to the mobile data transfer device sequentially or simultaneously.

Thereafter, the first channel data to be transferred through the first channel and the second channel data to be transferred through the second channel are generated using the backup data of the transfer terminal (S520).

In this case, the first channel data and the second channel data may be generated in at least one of the mobile data transfer device or the transfer terminal according to the configuration of the system.

In this case, the first channel may correspond to a wired channel based on a mobile data transfer device, and the second channel may correspond to a cloud based wireless channel.

In this case, the cloud may perform data transfer in such a manner that the backup data of the transfer terminal, that is, the second channel data is uploaded and stored through the network, and provided to the new terminal connected to the network.

In this case, the first channel data and the second channel data may be generated in consideration of at least one of data information, data capacity, data type, connection state of the wireless channel, and the performance of the transfer terminal that are previously stored in the cloud used in the wireless channel. have.

That is, the data corresponding to the data information previously stored in the cloud among the backup data may be generated as the second channel data so that it can be directly transferred from the cloud to the new terminal.

In addition, in case of backup data whose data capacity is larger than the predetermined reference capacity, the data may be uploaded to the cloud and then transferred to a wireless channel through the network.

In addition, when the data type is terminal data including important information of the transfer terminal or corresponds to the important data designated by the user, the first channel to perform data transfer through a wired channel that performs data transfer more stably than a wireless channel. Can be generated as data.

Also, it is determined whether the connection state of the wireless channel or the performance of the transfer terminal is good. If the connection state of the wireless channel and the performance of the transfer terminal are good, more second channel data may be generated to be transferred through the wireless channel. It may be.

Thereafter, data transfer between the first channel data and the second channel data is performed using the first channel and the second channel, respectively (S530). That is, the first channel data may be transferred to the new terminal using the first channel, and the second channel data may be transferred to the new terminal using the second channel.

In this case, the first channel and the second channel may share a transfer of backup data, that is, a first channel data and a second channel data. For example, the mobile data transfer device used for the first channel and the cloud used for the second channel share a process and information for transferring the backup data to each other so that efficient transfer can be performed according to the transfer situation.

In this case, in the case of the second channel data corresponding to the data information previously stored in the cloud, the second channel data previously stored in the cloud may be directly transferred to the new terminal without uploading the second channel data to the cloud. That is, the inconvenience of uploading data information already stored in the cloud back to the cloud from the transfer terminal or the mobile data transfer device is now

Therefore, before uploading the second channel data to the cloud, information stored in the cloud may be checked first.

Thereafter, it is determined whether the transfer of the first channel data is completed (S535). If the transfer of the first channel data is not completed, data transfer may be continuously performed.

In addition, when the transfer of the first channel data is completed as a result of the determination in step S535, it is determined whether the second channel data has been uploaded to the cloud (S545).

In this case, when all of the second channel data is uploaded to the cloud, even if the wired channel is disconnected, the second channel data may be transferred to the new terminal based on the cloud. That is, since the second channel data is transferred to the new terminal through the wireless channel, even if the data transfer in the first channel through the wired channel is completed and the connection is released, data transfer in the second channel can be continuously performed.

If the second channel data has not been uploaded to the cloud as a result of the determination in step S545, data transfer and upload may be continuously performed.

In addition, when the second channel data is uploaded to the cloud as a result of the determination in step S545, the transfer terminal and the new terminal are disconnected from the mobile data transfer device to release the connection of the first channel (S550).

Thereafter, the transfer of the second channel data is completed using the cloud (S560).

However, depending on whether the second channel data is uploaded to the cloud from the transfer terminal or the mobile data transfer device, the second channel is independent of disconnection of the first channel only when all of the second channel data is uploaded to the cloud. Data transfer may be performed continuously.

For example, when the second channel data is uploaded from the mobile data transfer device, after all the second channel data has been uploaded to the cloud, data transfer of the second channel is continuously performed regardless of disconnection of the first channel. Can be. If it is assumed that the first channel is disconnected while the second channel data is not uploaded from the mobile data transfer device to the cloud, the mobile data transfer device may complete the data transfer as soon as the first channel is disconnected. You can also decide to stop uploading. Therefore, in preparation for such a case, it is possible to check whether all of the second channel data has been uploaded and to disconnect the first channel.

In another example, when the second channel data is uploaded from the transfer terminal, even if the second channel data is not completely uploaded to the cloud, data transfer of the second channel may be continuously performed regardless of disconnection of the first channel. It may be. In such a case, since the second channel data uploads and transfers data without passing through the mobile data transfer device, data transfer of the second channel may be performed regardless of whether the first channel is disconnected.

6 is a block diagram showing a mobile data transfer device according to an embodiment of the present invention.

Referring to FIG. 6, the mobile data transfer device according to an embodiment of the present invention includes a communication unit 610, a channel data generation unit 620, a data transfer unit 630, and a storage unit 640.

The communication unit 610 may serve to transmit and receive data necessary for mobile data transfer through a communication network such as a network. In particular, the communication unit 610 according to an embodiment of the present invention may receive backup data for generating channel data from a transfer terminal, and transmit and receive first channel data and second channel data with the cloud. In addition, the communication unit 610 may transfer the first channel data to the new terminal.

The channel data generator 620 generates first channel data transferred to the first channel and second channel data transferred to the second channel by using backup data when transferring data between terminals.

In this case, the first channel data and the second channel data may be generated in at least one of a separate mobile data transfer device or a transfer terminal for mobile data transfer according to the configuration of the system.

For example, when the mobile data transfer device generates the mobile data transfer device, the mobile data transfer device may obtain backup data from the transfer terminal and generate first channel data and second channel data using the backup data. At this time, the transfer terminal may be connected to the mobile data transfer device by wire to transfer the backup data.

For another example, when the transfer terminal generates, when the transfer terminal is connected to the mobile data transfer device and is requested to generate the first channel data, the transfer terminal may generate the first channel data and the second channel data using the backup data. have.

In this case, the first channel data and the second channel data may be generated corresponding to the wired channel and the wireless channel, respectively.

For example, the first channel may correspond to a wired channel for directly connecting the transfer terminal and the new terminal to the mobile data transfer device for mobile data transfer. In addition, the second channel may correspond to a wireless channel through which the transfer terminal and the new terminal access the cloud for mobile data transfer through the network, respectively.

In this case, the cloud may correspond to a service in which a user may access various types of content or data by accessing the Internet through a terminal such as a laptop or a smart phone. That is, since various data can be stored freely after being stored in an external cloud server rather than in an internal storage space of a user's PC or a smart phone, contents having a large capacity can be used even in a terminal having insufficient storage space.

At this time, the transfer terminal and the new terminal may be connected to the mobile data transfer device corresponding to the wired channel using a separate jack.

In this case, the mobile data transfer device used in the wired channel is a device capable of executing mobile data transfer by being connected to a transfer terminal and a new terminal, and may correspond to a device connected to a communication network and capable of communicating with the cloud. For example, the mobile data transfer device may correspond to various terminals such as all information communication devices, multimedia terminals, wired terminals, fixed terminals, and IP (Internet Protocol) terminals. In addition, the mobile data transfer device, if the transfer terminal and the new terminal can be connected and can communicate with the cloud, mobile phones, Portable Multimedia Played (PMP), Mobile Internet Device (MID), smart phone (Smart Phone), Desktop (Desktop) Mobile with various mobile communication specifications such as tablet PC, tablet PC, note book, net book, personal digital assistant (PDA), smart TV and information communication device It may correspond to a terminal.

In this case, the first channel data and the second channel data may be generated in consideration of at least one of data information, data capacity, data type, connection state of the wireless channel, and the performance of the transfer terminal that are previously stored in the cloud used in the wireless channel. have.

In this case, the data information previously stored in the cloud may correspond to the mobile data information that the user backs up to the cloud at any time while using the transfer terminal. Accordingly, when data already stored in the cloud among the backup data of the transfer terminal exists, the corresponding data may be generated as the second channel data so that the transfer data can be transferred to the new terminal through the cloud.

In this case, as the at least one of the connection state of the wireless channel and the performance of the transfer terminal is better, more second channel data may be generated.

For example, it may be assumed that half of the backup data of the transfer terminal is generated as the first channel data and the other half is generated as the second channel data. At this time, if the connection state of the wireless channel is good and the speed at which the second channel data is uploaded from the transfer terminal and the rate at which the second channel data is transferred from the cloud to the new terminal is very fast, even if data of the same capacity is transferred, Transferring data using a channel may be more effective.

Therefore, before generating the first channel data and the second channel data, it is possible to determine how much to generate the second channel data by identifying the connection state of the wireless channel and the performance of the transfer terminal in advance.

For example, the data generation rate for each grade of the connection state of the wireless channel and the performance of the transfer terminal may be set in advance, and the first channel data and the second channel data may be generated at the data generation rate according to the corresponding grade. That is, when the connection status of the wireless channel and the performance of the transfer terminal are 1 grade, the first channel data and the second channel data may be generated at a ratio of 3 to 7. In addition, when the connection state of the wireless channel and the performance of the transfer terminal is a second level, the first channel data and the second channel data may be generated at a ratio of 4 to 6. In addition, when the connection state of the wireless channel and the performance of the transfer terminal is a grade 3 level, the first channel data and the second channel data may be generated at a ratio of 5 to 5. In addition, when the connection status of the wireless channel and the performance of the transfer terminal is a grade 4, the first channel data and the second channel data may be generated at a ratio of 6 to 4. In addition, when the connection state of the wireless channel and the performance of the transfer terminal is a grade 5, the first channel data and the second channel data may be generated in a ratio of 7 to 3.

At this time, the data generation rate is only one example according to the connection state of the wireless channel and the performance of the transfer terminal, and the second channel data according to the connection state of the wireless channel and the performance of the transfer terminal by applying various methods. Can be generated.

In this case, media data having a data capacity equal to or larger than a predetermined reference capacity among the backup data may be generated as second channel data.

For example, when the preset reference capacity corresponds to 1 GB, media data having a data capacity of 1 GB or more may be generated as second channel data.

In this case, the media data may be data including an image, a photo, a video, etc. except the terminal data.

In this case, data corresponding to terminal data whose data type is not media data among the backup data may be generated as first channel data. That is, the terminal data having a relatively high importance among the backup data may be generated as the first channel data so that data transfer may be performed through a wired channel having a relatively stable transfer environment than the wireless channel.

In this case, the terminal data may be generated as the first channel data for stable data transfer even if the data capacity is large.

In this case, the terminal data may correspond to data of high importance, such as an address book, text data, personal certificate, and the like. In this case, the terminal data may be designated by the user directly selecting an item to be included as the terminal data.

In this case, only the terminal data and the media data are described above, but various types of data may be set according to the setting.

In addition, for each of various data types, whether the first channel data is generated or the second channel data may be specified in advance.

In addition, the remaining data except for the terminal data may be generated by classifying the first channel data and the second channel data according to other conditions except for the data type.

For example, if the user wishes to transfer the application data and the media data to the second channel, the application data and the media data may be generated as the second channel data regardless of other conditions.

In this case, the application data may include both data related to the installation of the application installed in the transfer terminal and data stored by the user.

The data transfer unit 630 transfers the first channel data to the new terminal using the first channel, and transfers the second channel data to the new terminal using the second channel. That is, the first channel data may be transferred to the new terminal through the first channel through the mobile data transfer device, that is, the wired channel. In addition, the second channel data may be transferred to a new terminal through a second channel through the cloud, that is, a wireless channel.

At this time, the first channel and the second channel may be shared in the transfer of the backup data. For example, the mobile data transfer device used for the first channel and the cloud used for the second channel share a process and information for transferring the backup data to each other so that efficient transfer can be performed according to the transfer situation.

For example, the shared information may include information of backup data classified as first channel data, information of backup data classified as second channel data, data transfer rate through a first channel, data transfer situation through a first channel, The data transfer rate through the second channel, the connection state of the second channel, the data transfer situation through the second channel, the cloud upload situation of the second channel data, and the like. That is, various information that may occur in the process of transferring the backup data can be shared.

In this case, in the case of the second channel data corresponding to the data information previously stored in the cloud, the second channel data previously stored in the cloud may be directly transferred to the new terminal without uploading the second channel data to the cloud. That is, the unnecessary transfer process of uploading the data information previously stored in the cloud back to the cloud in the transfer terminal or the mobile data transfer device may be omitted, thereby improving the data transfer speed in the second channel.

Therefore, the information stored in the cloud can be checked before uploading the second channel data to the cloud.

For example, a transfer terminal or a mobile data transfer device capable of uploading second channel data may be connected to a cloud to check storage information.

In this case, when all of the second channel data is uploaded to the cloud, even if the wired channel is disconnected, the second channel data may be transferred to the new terminal based on the cloud. That is, since the second channel data is transferred to the new terminal through the wireless channel, even if the data transfer in the first channel through the wired channel is completed and the connection is released, data transfer in the second channel can be continuously performed.

However, depending on whether the second channel data is uploaded to the cloud from the transfer terminal or the mobile data transfer device, the second channel is independent of disconnection of the first channel only when all of the second channel data is uploaded to the cloud. Data transfer may be performed continuously.

For example, when the second channel data is uploaded from the mobile data transfer device, after all the second channel data has been uploaded to the cloud, data transfer of the second channel is continuously performed regardless of disconnection of the first channel. Can be. If it is assumed that the first channel is disconnected while the second channel data is not uploaded from the mobile data transfer device to the cloud, the mobile data transfer device may complete the data transfer as soon as the first channel is disconnected. You can also decide to stop uploading. Therefore, in preparation for such a case, it is possible to check whether all of the second channel data has been uploaded and to disconnect the first channel.

In another example, when the second channel data is uploaded from the transfer terminal, even if the second channel data is not completely uploaded to the cloud, data transfer of the second channel may be continuously performed regardless of disconnection of the first channel. It may be. In such a case, since the second channel data uploads and transfers data without passing through the mobile data transfer device, data transfer of the second channel may be performed regardless of whether the first channel is disconnected.

In this case, the above example corresponds to one example that can be variously applied according to the mobile data transfer system, there may be various embodiments depending on the setting of the transfer terminal, the new terminal, the mobile data transfer device and the cloud.

At this time, when the transfer of any one channel data of the first channel data and the second channel data is completed first, a portion of the channel data that has not yet been transferred can be transferred to the channel where the transfer is completed can be transferred to the new terminal. .

For example, it may be assumed that data transfer by the first channel is completed but data transfer by the second channel is not yet completed. In this case, data transfer may be performed more efficiently by transferring a part of the second channel data to the mobile data transfer device and transferring the data to the new terminal.

As another example, it may be assumed that data transfer by the second channel is completed but data transfer by the first channel is not yet completed. At this time, a part of the first channel data may be transferred to the cloud and transferred to the new terminal. However, if the first channel data, which has not yet completed data transfer, corresponds to data set to be transferred only through the first channel like the terminal data, data transfer may be performed through the first channel even though it takes longer. .

The storage unit 640 stores various information generated in the mobile data transfer process in the embodiment of the present invention as described above.

According to an embodiment, the storage unit 640 may be configured independently of the mobile data transfer device to support a function for mobile data transfer. At this time, the storage unit 640 may operate as a separate mass storage, and may include a control function for performing the operation.

On the other hand, the mobile data transfer device is equipped with a memory can store information in the device. In one embodiment, the memory is a computer readable medium. In one implementation, the memory may be a volatile memory unit, and for other implementations, the memory may be a nonvolatile memory unit. In one embodiment, the storage device is a computer readable medium. In various different implementations, the storage device may include, for example, a hard disk device, an optical disk device, or some other mass storage device.

By using such a mobile data transfer device, data transfer of a mobile terminal can be more efficiently performed using two channels.

In addition, by transferring sensitive information such as user's personal information to a wireless channel instead of a transfer PC, personal information can be prevented from being leaked through the transfer PC, and information can be shared between wired and wireless channels when transferring mobile data. It may be possible to complete data transfers more quickly by transferring more data to a smoother channel.
