2. DESCRIPTION OF THE RELATED ART

[0003] Nowadays, using only mobile terminals, users can use various additive functions, for example games, a digital camera, an MP3 player, a scheduler, a housekeeping book and directory functions. Among the functions, users mainly use high-capacity services based on multimedia data, for example, games, still image data, moving image data and MP3 music data. However, mobile terminals have relatively small storage spaces compared with the high-capacity services, and thus the mobile terminals have a limitation in storing multimedia data.

[0004] In order to improve a multimedia data storage rate of a mobile terminal, various techniques have been introduced, for example, to expand the capacity of an internal memory of a mobile terminal, mounting a memory card externally on a mobile terminal, transmitting data of a mobile terminal to a Personal Computer (PC) using a Universal Serial Bus (USB) cable, and storing mobile terminal data on the Internet through a wireless Internet connection.

[0005] However, expanding the capacity of an internal memory has a problem of increased size of a mobile terminal caused by expansion of the size of the internal memory. Mounting a memory card externally on a mobile terminal has a problem of carrying the mobile terminal with a memory card so as to use multimedia data stored in the memory card. Transmitting mobile terminal data to a PC using a USB cable has a problem of carrying the mobile terminal with a USB cable for connecting to a PC so as to store data stored in the mobile terminal into the PC, otherwise it is impossible to store data in a PC, and the PC also needs to be turned on and be connected to the USB cable. Storing mobile terminal data on the Internet has a relatively slower data transmission speed than transmitting mobile terminal data to a PC, and requires connection to a wireless Internet for data transmission, thereby increasing costs.

The same reference symbols identify the same or corresponding elements in the drawings. Detailed descriptions of constructions or processes known in the art may be omitted to avoid obscuring the invention in unnecessary detail.

[0027] Referring to FIG. 1, the system includes a mobile terminal 100, a wireless connection device 200, and a web server 300.

[0028] The mobile terminal 100 has a wireless LAN card therein to use a wireless LAN service, and transmits data stored therein to the web server 300 using the wireless LAN service. For this purpose, as shown in FIG. 2, the mobile terminal 100 preferably includes a wireless unit 110; an input unit 120; a control unit 130, which includes a setting unit 131, a sensing unit 132, and a transmitting unit 133; a display unit 140; and a storage unit 150.

[0029] The wireless connection device 200 is installed to set a wireless LAN service area. The wireless LAN service area is an area where a wireless LAN service is available, and covers a predetermined distance from a location where the wireless connection device 200 is installed.

[0030] The web server 300 provides a web storage service for storing data of the mobile terminal 100. For this purpose, as shown in FIG. 3, the web server 300 preferably includes a control module 310, a web storage 320 and a file module 330.

[0031] A main configuration of the mobile terminal 100 is described in detail with reference to FIG. 2. The wireless unit 110 executes wireless communications between the mobile terminal 100 and a mobile network. For example, the wireless unit 110 transmits and receives voice data, text messages and multimedia messages through a wireless network.

[0032] The input unit 120 may include keypads, touch screens, touch pads or scroll wheels, and receives operating signals input by a user for controlling an operation of the mobile terminal 100 and provides the operating signals to the control unit 130.

[0033] The control unit 130 controls the whole operation to be executed through units of the mobile terminal 100. In particular, the control unit 130 sets synchronization of the web server 300 and the mobile terminal 100, obtains member authentication from the web server 300, and transmits data of the mobile terminal 100 to the web server 300. For this purpose, the control unit 130 preferably includes the setting unit 131, the sensing unit 132 and the transmitting unit 133.

[0034] The setting unit 131 sets synchronization of the web server 300 and the mobile terminal 100 by a hotkey, or by a callback Uniform Resource Locator (URL) or URL address of the web server 300. The setting unit 131 also sets a specific data stored in the mobile terminal 100 to be stored into the web storage 320. For example, the specific data may be directory data, moving image data, still image data, or MP3 music data. The setting unit 131 also sets a user ID and password by subscribing to the web server 300 to store the specific data into the web storage 320.

[0035] The sensing unit 132 senses whether the mobile terminal 100 enters or exits a wireless LAN service area by sensing signals of the wireless connection device 200.

[0036] When the sensing unit 132 senses that the mobile terminal 100 enters a wireless LAN service area, the transmitting unit 133 transmits data of the mobile terminal 100 set by the setting unit 131 to the web server 300 through a broadband network. When the sensing unit 132 senses that the mobile terminal 100 exits the wireless LAN service area during data transmission to the web server 300, the transmitting unit 133 stops transmission of the data of the mobile terminal 100. Thereafter, if the sensing unit 132 senses that the mobile terminal 100 reenters the wireless LAN service area, the transmitting unit 133 retransmits the data, transmission of which to the web server 300 was stopped due to the mobile terminal 100 exiting the wireless LAN service area, from a stopped portion of transmitted data or from a start of the data transmission.

[0037] The display unit 140 displays the state and result of various operations executed in units of the mobile terminal 100, and a plurality of information, by control of the control unit 130. Particularly, when data of the mobile terminal 100 set by the setting unit 131 is completely stored into the web storage 320, the display unit 140 displays a storage completion message. When the mobile terminal 100 exits the wireless LAN service area, the display unit 140 displays a warning message informing that data transmission has stopped. If the mobile terminal 100 reenters the wireless LAN service area, the display unit 140 displays a message to select whether the transmitting unit 133 should retransmit the data whose transmission was stopped from a stopped portion of the data or from the start of the data.

[0038] The storage unit 150 stores data (for example, a setting state or data about a menu) related to operation of the mobile terminal 100 by control of the control unit 130. The storage unit 150 also stores a hotkey, or a callback URL or URL address of the web server 300 for setting synchronization of the web server 300 with the mobile terminal 100 by the setting unit 131, and stores specific data of the mobile terminal 100 to be stored into the web storage 320 provided by the web server 300. The storage unit 150 also stores the user ID and password required for connection to the web server 300 set by the setting unit 131.

[0039] Referring to FIG. 3, the control module 310 controls the whole operation to be executed in the units of the web server 300. Particularly, the control module 310 executes member authentication through the user ID and password set in the mobile terminal 100.

[0040] The web storage 320 stores data of the mobile terminal 100 transmitted to the web server 300 through a broadband network by control of the control module 310.

[0041] In the case that specific data stored in the web storage 320 is lost or damaged, the file module 330 executes a system file check by changing the name of the data and restoring the data into a stored version of the data by control of the control module 310.

[0042] Referring to FIG. 4, the control unit performs setting of the mobile terminal 100 and the web server 300 so as to transmit data of the mobile terminal 100 to the web server 300 (S10). Step S10 of performing setting is described in detail with reference to FIG. 5 as follows.

[0043] Referring to FIG. 5, the control unit 130 sets synchronization of the web server 300 and the mobile terminal 100 by a hotkey, a callback URL or a URL address so as to store specific data stored in the storage unit 150 of the mobile terminal 100 into the web storage 320 provided by the web server 300, in step S11. The control unit 130 sets the user ID and password for connection to the web server 300 set at step S11, in step S12, then sets the specific data stored in the storage unit 150 of the mobile terminal 100 to be stored into the web storage 150, in step S13. The specific data may be directory data, moving image data, still image data or MP3 music data. The specific data may be set by the user whenever the mobile terminal 100 enters the wireless LAN service area, or may be set previously by the user to be automatically executed when the mobile terminal 100 enters the wireless LAN service area. Preferably, performing setting at step S10 is executed by the setting unit 131 of the control unit 130.

[0044] The control unit 130 senses whether the mobile terminal 100 enters the wireless LAN service area having the wireless connection device 200, in step S20. Preferably, the sensing is executed by the sensing unit 132 of the control unit 130.

[0045] If the control unit 130 senses that the mobile terminal 100 enters the wireless LAN service area, the control unit 130 transmits the user ID and password set for connection to the web server 300 to determine whether the user of the mobile terminal 100 is authenticated by the web server 300 as a member of the web server 300 in step S30. Member authentication may be obtained by inputting the ID and password whenever the mobile terminal 100 is connected to the web server 300, or may be obtained when synchronization of the mobile terminal 100 with the web server 300 is executed, and thus in the case of reconnection, the authentication step may be omitted.

[0046] If the user is authenticated as a member of the web server 300, the control unit 130 is connected to the web server 300 in step S40.

[0047] The control unit 130 then transmits the set specific data of the mobile terminal 100 to the web server 300 through a broadband network in step S50. Preferably, the transmission of the data is executed by the transmitting unit 133 of the control unit 130.

[0048] The sensing unit 132 of the control unit 130 senses whether the mobile terminal exits the wireless LAN service area during data transmission in step S60. If the mobile terminal 100 exits the wireless LAN service area during data transmission, the control unit 130 controls the display unit 140 to display a warning message notifying that data transmission is stopped and controls the transmission unit 133 to stop data transmission to the web server 300 in step S70.

[0049] The sensing unit 132 of the control unit 130 senses whether the mobile terminal 100 reenters the wireless LAN service area in step S80. If the mobile terminal 100 reenters the wireless LAN service area, the control unit 130 determines whether to retransmit the data whose transmission was stopped in step S90. If the data is to be retransmitted, the transmission unit 133 retransmits the data from a stopped portion of the data or from the start of the data in step S100.

[0050] If the mobile terminal 100 does not exit the wireless LAN service area at step S60, the control unit 100 continues transmission of the set specific data to the web server 300 through a broadband network, and the process continues at step S110.

[0051] The web storage 320 of the web server 300 stores the data transmitted from the transmitting unit 133 of the mobile terminal 100 by control of the control module 310 in step S110.

[0052] When the data transmitted from the transmitting unit 133 of the mobile terminal 100 to the web server 300 is completely stored into the web storage 320, the control unit 130 controls the display unit 140 to display a storage completion message in step S120.

[0053] As described above, the present invention has an effect of expanding a storage space for storing mobile terminal data to a web storage, thereby reducing a limitation of the storage space.

[0054] The present invention also has an effect of storing data of a mobile terminal into a web storage without requiring a connecting cable between the mobile terminal and a PC, thereby overcoming a problem of limited space and equipment.

[0055] Further, the present invention has an effect of storing data of a mobile terminal into a web storage in a wireless LAN service area, thereby reducing costs rendered in connection to a wireless Internet.

[0056] While exemplary embodiments of the present invention have been shown and described in this specification, it will be understood by those skilled in the art that various changes or modifications of the embodiments are possible without departing from the spirit and scope of the invention as defined by the appended claims.
