Figures 2 and 3 are diagrams that are referenced to outline a method of setting synchronization in a mobile device according to the present invention.

Referring to FIG. 2, the first mobile device 100a, which has been gold-sampled, backs up system-related data that the user needs. At this time, the backup data includes various system setting data, installed app data, barcode scanner setting data, and OS update image. In addition, backup data generated by backup can be encrypted or compressed and encrypted.

The first mobile device 100a executes a server function for transmitting the generated backup data to one or more other mobile devices 100b to 100n. Accordingly, the one or more other mobile devices 100b to 100n are directly connected to the first mobile device 100a to receive the backup data from the first mobile device 100a, After installation, reboot is performed.

With this process, setting items can be synchronized by collectively applying setting items to a plurality of devices.

In addition, the server function for transmitting the backup data may be executed simultaneously in the second mobile device 200a using a different server name from the first mobile device 100a. That is, a plurality of devices can simultaneously perform a server function and transmit backup data to a plurality of devices, thereby synchronizing configuration items.

In addition, as shown in FIG. 3, the second mobile device 100b receiving the backup data performs the server function again and transmits the backup data to another mobile device 210ab-210n to be installed .

That is, after the backup data is transmitted from the first mobile device 100a to the second mobile device 100b, the backup data is rebooted, the server function is automatically executed, and the backup data is transmitted to another mobile device 210ab To < RTI ID = 0.0 > 210n. ≪ / RTI >

In addition, the server function can be configured not to be performed after the predetermined server step. That is, the case where the first mobile device 100a transmits the backup data to one or more other mobile devices 100b through 100n is referred to as a first hierarchical server step and the second mobile device 100b transmits another backup data to another mobile device 210ab through 210n ) Can be defined as a second layer server step or the like. At this time, if the server function is restricted after the second layer server step, the other mobile devices 210ab to 210n can not automatically perform the server function after rebooting.

4 and 5 are flow charts provided in the description of a method of setting synchronization in a mobile device according to the first embodiment of the present invention. FIG. 4 illustrates an operation process in a mobile device providing a server function, and FIG. 5 illustrates an operation process in a mobile device performing a client function of receiving and installing a backup file.

Referring to FIG. 4, in a mobile device that performs a server function, a user selects data to be backed up through a backup file selection screen and stores the selected data as backup data (S300). The backup data is various system setting data, installed app data, barcode scanner setting data, and OS update image.

Next, the user activates the server function for transmitting the backup data (S305).

If the activation of the server function is selected, a server name set as a default is set in advance (S310). If the set server name is already used by another device (S315), the server name is changed to another server name (S320). This process is repeated until a server name that is not used by another device can be set.

For example, if you set the default server name to 'CloneServer00' and this server name is already being used on another device, the server name will be changed to 'CloneServer01' -> 'CloneServer02' -> 'CloneServer03' Change the name to use it.

If the set server name is not used by another device, the server function is performed with the set server name (S325).

When the server function is performed, the backup data can be directly transmitted according to a request from another mobile device without going through an AP or the like.

Referring to FIG. 5, when a mobile device that performs a client function of receiving and installing a backup file executes an associated application (S350), a server searching for a mobile device performing an adjacent server function is performed (S355). When searching for a server, you can search for the server by changing the server name.

For example, you can connect to 'CloneServer00' and connect with this server name. Otherwise, search for the server by changing the server name as 'CloneServer01' -> 'CloneServer02' -> 'CloneServer03'.

After the server is searched, if the searched server can be registered as a client (S360), it is communicably connected by requesting registration, receiving registration, etc., and performs a client function (S365). Thereafter, the backup data is directly received from the mobile device performing the server function (S370).

Mobile devices that perform server functions and mobile devices that perform client functions can use Wi-Fi hotspot communication technology to send and receive backup data directly without connecting the device to a separate network. Wi-Fi hotspot communication technology supports tethering mode between devices without going through Wi-Fi Access Point (AP), enabling 1: N connection.

However, it may be configured to send and receive backup data using other local communication technologies besides Wi-Fi communication technology.

Then, the received backup data is installed (S375), and a process of rebooting is performed (S380). After rebooting, a message or an icon indicating that the received backup data has been installed can be displayed, and the name, type, function, version, size and the like of the backup data can be checked by selecting the message or icon.

With this process, you can set the backup data.

6 to 12 are diagrams referred to the description of a method of setting synchronization in a mobile device according to the first embodiment of the present invention.

6 shows an example of a backup file selection screen.

As shown in FIG. 6, the user can select a backup of the desired data on the backup file selection screen 400. FIG. When the selection of the data to be backed up is completed, as shown in FIG. 7, a screen 410 for selecting a storage location of the backup data and whether or not to perform backup can be displayed.

8 shows a screen for activating the server function.

In the activation screen 420 as shown in Fig. 8, the user selects an icon 423 with a wireless display on the right side of the backed up file, and as shown in Fig. 9, The user can display the screen 430 in which the user can select the activation of the user.

FIGS. 10 to 12 show screens displayed on a mobile device receiving backup data.

When the related application is executed in the mobile device performing the client function, a screen 440 for searching the mobile device performing the server function is displayed as shown in FIG.

When the search for the mobile device performing the server function is completed, as shown in FIG. 11, a screen 450 is displayed that is communicably connected to the mobile device performing the server function and receives the backup data.

When the reception of the backup data is completed, as shown in FIG. 12, the system setting data, installed app data, bar code scanner setting data, OS update image and the like are automatically installed and rebooted.

By this process, the same operation can be performed in a plurality of devices, and the settings can be synchronized.

13 to 16 are flowcharts provided in a description of a setting synchronization method in a mobile device according to a second embodiment of the present invention. FIGS. 13 to 15 show an operation process in a mobile device providing a server function, and FIG. 16 shows an operation process in a mobile device that performs a client function of receiving and installing a backup file.

Referring to FIG. 13, in a mobile device that performs a server function, a user selects data to be backed up through a backup file selection screen (S500). The backup data includes various system setting data, installed application data, barcode scanner setting data , And OS update images.

The user can select whether or not to set encryption when generating the backup data (S505). When the encryption setting is selected, encrypted backup data is generated (S510). If the encryption setting is not selected, general unencrypted backup data is generated (S515). When creating encrypted backup data, you can set a password for decryption.

Referring to FIG. 14, in response to a user's command, the controller 190 activates a server function for transmitting backup data (S530).

If the backup data to be transmitted through the server function is encrypted (S535), the password is input (S540). If the input password and the preset password match, a server name that is set as a default is set for transmission (S550). If the set server name is already used by another device (S555), the server name is changed to another server name (S560). This process is repeated until a server name that is not used by another device can be set.

For example, if you set the default server name to 'CloneServer00' and this server name is already being used on another device, the server name will be changed to 'CloneServer01' -> 'CloneServer02' -> 'CloneServer03' Change the name to use it.

If the set server name is not used by another device, the server function is performed with the set server name, and the encrypted backup data and the password (PW) can be directly transmitted according to a request from another mobile device without going through the AP or the like S565).

When the delivery of the backup data is completed and the server function is terminated, the password PW is deleted (S570).

In addition, it is possible to delete the password if the backup data is transmitted a predetermined number of times. If there is a request from a predetermined number or more of mobile devices, the server function may be terminated.

Referring to FIG. 15, if the server function is activated for transmission of backup data and the backup data to be transmitted is not encrypted, a default server name is set in step S575.

If the set server name is already used by another device (S315), the server name is changed to another server name (S580). This process is repeated until a server name that is not used by another device can be set.

If the set server name is not used in another device, the server function may be performed with the set server name, and the backup data may be directly transmitted (S590) without going through the AP or the like in response to a request from another mobile device.

Referring to FIG. 16, in step S605, a mobile device performing a client function of receiving and installing a backup file executes an associated application (S600), and performs a server search for a mobile device performing an adjacent server function (S605). When searching for a server, you can search for the server by changing the server name.

For example, you can connect to 'CloneServer00' and connect with this server name. Otherwise, search for the server by changing the server name as 'CloneServer01' -> 'CloneServer02' -> 'CloneServer03'.

After the server is searched, if it is possible to register the searched server as a client (S610), it is communicably connected by requesting registration and receiving registration, and performs a client function (S615). Thereafter, the backup data is received directly from the mobile device performing the server function (S620).

Mobile devices that perform server functions and mobile devices that perform client functions use Wi-Fi hotspot communication technology, so they can send and receive backup data directly without connecting the device to a separate network . Wi-Fi hotspot communication technology supports tethering mode between devices without going through Wi-Fi Access Point (AP), enabling 1: N connection.

However, it may be configured to send and receive backup data using other local communication technologies besides Wi-Fi communication technology.

If the received backup data is the encrypted backup data (S625), the backup data is decrypted using the received password PW, and the backup data is installed (S630).

After the backup data is installed, the password PW is deleted (S635) and rebooted (S640).

If the password is deleted, only the encrypted backup data exists in the mobile device performing the server function and the mobile device performing the client function, and the encrypted backup data can be decrypted only by the administrator who generated this file .

If the received backup data is general unencrypted backup data, the received backup data is installed (S645) and rebooted (S650).

After rebooting, a message or an icon indicating that the received backup data has been installed can be displayed, and the name, type, function, version, size and the like of the backup data can be checked by selecting the message or icon.

In this way, it is possible to make settings by using encrypted backup data or unencrypted backup data.

In addition, the second mobile device, which receives the backup data from the first mobile device, automatically performs the server function and transmits the backup data to another third mobile device performing the client function so as to be installed It is possible. That is, the second mobile device that has performed the client function installs the backup data, reboots the data, activates the server function directly without selecting the user, enables the backed up data to be transmitted to the third mobile device, If there is no client registration request from another mobile device, the server function can be configured to be terminated.

In the case where the backup data is encrypted, the second mobile device that receives the backup data and performs the server function again does not delete the password immediately after the backup data is installed, So that the password can be configured to be deleted when the server function is terminated. At this time, the time information defined to delete the password can be transmitted together with the encrypted backup data and the password set by the first mobile device that has performed the server function for the first time.

Likewise, when transmitting the encrypted backup data from the second mobile device to the third mobile device, the time information defined to delete the password can be generated and transmitted together. The time defined for deleting such a password can be set by adding a predetermined time from the rebooting time.

Also, when the backup data encrypted by the first mobile device a predetermined number of times is transmitted to another mobile device, the password may be automatically deleted.

In addition, the server function can be configured not to be performed after the predetermined server layer step. For example, a case where backup data is transmitted to a second mobile device by performing a first mobile device server function is referred to as a first layer server step, a second mobile device performs a server function again to transmit backup data to a third mobile device If the third mobile device performs the server function again, the third mobile device performs the server function again and transmits the backup data to the fourth mobile device. In this case, After the third layer server step is performed, the fourth mobile device can be configured not to perform the server function again.

For such a configuration, together with the encrypted backup data and the password, time information defined to delete the password, information on the current hierarchical server step, and the like can be transmitted together.

When "Direct Clone" is selected, a window for inputting a password is displayed as shown in FIG. 19 (c). When the input password matches the set password, the server function is activated. When the password is incorrect, A window for re-entering the password is displayed as shown in (d) of Fig. When 'Delete' is selected, the backup data is deleted immediately without entering the password.

As shown in FIG. 20, in the case of a general backup data in which a password is not set, 'Restore', 'Direct Clone', and 'Delete' can be performed according to the selection without asking for a password.

FIG. 21 shows a screen displayed when the backup data is transmitted according to the activation of the server function. 21 (a) shows the start of the hotspot for activation of the server function, and FIG. 21 (b) shows the screen displayed after the hotspot is activated. In this screen, you can cancel the server function by selecting 'Cancel'.
