| 20090073983 | METHOD AND APPARATUS FOR PROVIDING GATEWAY TO TRANSMIT IPv6 PACKET IN A WIRELESS LOCAL AREA NETWORK SYSTEM - A method and apparatus for providing a gateway for IPv6 packet transmission in a WLAN system are provided, in which a gateway takes over a TCP/IP protocol stack from a legacy 6LoWPAN node for providing a gateway for IPv6 packet transmission in a WLAN system. One or more service request messages for data communications are received from a plurality of 6LoWPAN nodes, and a virtual interface is generated for allocating IPv6 addresses to the 6LoWPAN nodes by adding a predetermined IPv6 address prefix to addresses of the 6LoWPAN nodes set in the service request messages. A socket adaptation layer is interfaced for receiving the IPv6 addresses from the virtual interface and transmitting data packets to the 6LoWPAN nodes, and when data packets are transmitted and received to and from the 6LoWPAN nodes, an on-going file is controlled and managed, and the data packets are routed. | 03-19-2009 |
| 20090161581 | ADDRESS AUTOCONFIGURATION METHOD AND SYSTEM FOR IPv6-BASED LOW-POWER WIRELESS PERSONAL AREA NETWORK - An IP address autoconfiguration method and system of an IPv6-based Low Power WPAN for reducing network traffics is applicable for an Internet Protocol (IP) based network including a plurality of devices. The address autoconfiguration method generates and broadcasts, at a first device, a beacon frame containing an adaptive router advertisement (RA) message having prefix information, and configures, at a second device received the beacon frame, an IP address using the prefix information extracted from the adaptive RA message carried by the beacon frame and a physical address of the second device. The system includes a first type device which broadcasts a beacon frame carrying a prefix; at least one second type device which relays the prefix using a beacon frame; and at least one terminal device which configures an IP address using the prefix in the beacon frame and a physical address of the terminal device. | 06-25-2009 |
| 20100202355 | METHOD FOR SUPPORTING ROUTE OPTIMIZATION IN 6LoWPAN BASED MANEMO ENVIRONMENT - A method is provided for registering a mobile router in an Internet Protocol version 6 over Low power Wireless Personal Area Network (6LoWPAN) network. The mobile router detects movement into a wireless network through the reception of a beacon message, and sends a Router Solicitation (RS) message requesting registration in the wireless network to a gateway. The gateway acquires an address of the mobile router from the RS message, stores the acquired address, assigns a new address to be used in the wireless network to the mobile router, and sends a Router Advertisement (RA) message with assigned address information and gateway address information, to the mobile router. The mobile router acquires the assigned address information and the gateway address information from the RA message. | 08-12-2010 |
| 20100202357 | METHOD FOR SUPPORTING MOBILITY OF A MOBILE NODE IN A MULTI-HOP IP NETWORK AND A NETWORK SYSTEM THEREFOR - A method is provided for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, in which an MN that has moved from a source Personal Area Network (PAN) to a target PAN, sends a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN, and receives a Router Advertisement (RA) message from the gateway in response to the RS message. The RA message includes a home prefix of the MN as the requested profile. The method supports mobility of MNs, enables unicast communication, and facilitates efficient use of the network. | 08-12-2010 |
| 20100210293 | OPERATION METHOD AND SYSTEM OF MOBILE TERMINAL - An operation method and system of a mobile terminal connected to an electronic device is provided. The electronic device extracts a content corresponding to a user selection from among contents displayed on a screen, and delivers to the mobile terminal the extracted content and functional application information and command of a mobile terminal that will execute the extracted content. The mobile terminal receives the extracted content and the functional application information and command, and executes the functional application according to the command using the extracted content. | 08-19-2010 |
| 20100211785 | SYSTEM AND METHOD FOR AUTOMATIC WIRELESS CONNECTION BETWEEN A PORTABLE TERMINAL AND A DIGITAL DEVICE - A method and system are provided for automatic wireless connection to a digital device in a portable terminal, wherein information about the portable terminal is acquired. The information about the portable terminal is commonly used for automatic wireless connection to the digital device. A state of a Wireless Local Area Network (WLAN) is checked and activated, and the WLAN is set to an Ad-hoc mode. A Service Set Identifier (SSID) of the WLAN is set using the acquired portable terminal information, a security key of the WLAN is set using the acquired portable terminal information, and an Internet Protocol (IP) address of the WLAN is automatically set using the acquired portable terminal information. | 08-19-2010 |
| 20100251122 | METHOD AND APPARATUS FOR CONTROLLING PRESENTATION SLIDES - A presentation control system and method are provided, in which a first terminal is connected to a second terminal to control displaying of a presentation file stored in the second terminal. The first terminal controls execution of the presentation file in the second terminal, controls execution of switching between slide pages included in the presentation file in the second terminal, and controls closing of the presentation file in the second terminal. | 09-30-2010 |
| 20100325425 | METHOD FOR AUTOMATIC WLAN CONNECTION BETWEEN DIGITAL DEVICES AND DIGITAL DEVICE THEREFOR - A method and apparatus for performing an automatic wireless connection with a second digital device by a first digital device is provided. The method includes acquiring, by the first input device, random information used for the wireless connection; checking a status of a Wireless Local Area Network (WLAN); storing the checked status; setting the WLAN to an Ad-hoc mode; setting a Service Set Identifier (SSID) of the WLAN using the random information; setting a security key of the WLAN using the random information; and setting an Internet Protocol (IP) address of the WLAN using the random information. | 12-23-2010 |
| 20110010643 | DEVICE AND METHOD FOR PERFORMING REOMOTE INTERNET BROWSING BETWEEN PORTABLE DEVICES - A method and apparatus for performing Internet browsing, in which a remote communication-enabled device accesses Internet, and connects a web browsing device to the Internet through local communication. The remote communication-enabled device additionally transmits control commands and input information for controlling a web browser to the web browsing device, which in turn runs a web browser using the received control information. | 01-13-2011 |
| 20110063663 | METHOD FOR PRINTING DOCUMENT OF MOBILE TERMINAL THROUGH PRINTER, AND MOBILE TERMINAL THEREFOR - A method for printing a document of a mobile terminal without a separate printer setup is provided. The method includes performing a wireless auto-connection between a mobile terminal and a printer located near the mobile terminal, and when the mobile terminal transmits a document to be printed to the printer, the printer finds a computer capable of outputting the document, transmits the document to the computer, and prints the document in response to a print instruction received from the computer. Accordingly, a user can print various documents stored in the mobile terminal wherever a printer is located, even without information of the printer. | 03-17-2011 |
| 20110154255 | APPARATUS AND METHOD FOR SYNCHRONIZATION BETWEEN DEVICES THROUGH WIRELESS CONNECTION - An apparatus and method for synchronization between devices through a wireless connection are provided.
