Abstract:
An apparatus and a method for setting up a communication link in a wireless communication system are provided. The terminal exchanges at least one information of group formation information required to negotiate a role between the terminal and a counterpart terminal, Internet Protocol (IP) allocation information required for IP allocation and Address Resolution Protocol (ARP) information required for exchange of ARPs, with the counterpart terminal. The terminal sets up a main communication link between the terminal and the counterpart terminal based on the exchanged at least one information.
Abstract:
Provided is a mode-based access control method that includes: making a security mode list which indicates security setting states of devices existing in a home network; setting a specific security mode selected from the modes on the security mode list; and making the devices perform functions thereof in the specific security mode. Also, provided is a mode-based access control device includes: an authentication unit which checks information on a user and authenticates the user; a mode configuration unit which makes a security mode list indicating the security setting state of devices forming a home network; a mode setting unit which sets a specific security mode selected from modes on the security mode list; and an operating unit which causes the devices to perform functions thereof in the specific security mode.
Abstract:
A demand response apparatus receives from a supply resource utilizing apparatus a signal indicating whether power supply from the demand response apparatus to the supply resource utilizing apparatus is possible, estimates a first power usage of the demand response apparatus for a first time interval, changes an operation of the demand response apparatus, estimates a second power usage for a second time interval after the changing of the operation of the demand response apparatus, calculates supply power available to the supply resource utilizing apparatus based on the estimated first power usage and the estimated second power usage, and transmits information about the available supply power to the supply resource utilizing apparatus.
Abstract:
The present disclosure relates to a method and a device for transmitting content to a display device. The content transmission method includes: receiving a display type from a sink device; generating content in view of the display type; and transmitting the generated content to the sink device, wherein the display type includes information indicating a set type of a display of the sink device.
Abstract:
A method and device for executing an object on a display. The method of executing an object includes receiving a user input to an object displayed on a display; gradually enlarging and displaying the object; and executing the application corresponding to the object as the object is enlarged.
Abstract:
An apparatus and method for improving performance of a service based on Wi-Fi direct connection by verifying URI information for controlling a P2P client in a device discovery process of a MAC layer when providing a UPnP service function based on the Wi-Fi direct connection is provided. The apparatus includes a message sending unit for sending a device discovery request, a message receiving unit for receiving a response message, including URI information of a P2P client, for the device discovery request, a message analyzing unit for acquiring the URI information included in the response message, and a service controller for performing a UPnP service function based on the Wi-Fi direct connection using the acquired URI information when connecting with the P2P client, wherein the device discovery request is a device discovery request of a Wi-Fi MAC layer.

Abstract:
Provided is a method for discovering a device for Peer-to-Peer (P2P) communication by a first device in a Wireless Fidelity (Wi-Fi) communication system. when receiving a discovery information request from a new device, the first device determines whether there is a second device that cannot be newly connected, among currently connected devices. If there is the second device, the first device generates a discovery information response based on the second device, and sends the discovery information response to the new device.
Abstract:
A method and an apparatus for transmitting data on a wireless connection is provided. The method includes selecting a device to receive data; transmitting, to the device, a first signal including attribute information about the data, before an establishment of a wireless connection with the device is completed; receiving, from the device, a second signal indicating whether the transmission of the data is accepted by the device; and establishing the wireless connection with the device to transmit the data through the wireless connection, in response to reception of the second signal indicating the transmission of the data is accepted.
Abstract:
An apparatus and method for collecting power from distributed power supply resources are provided. The method includes transmitting a signal for inquiring whether supply of demand-side power supply resources is possible to a providing side that provides demand-side power supply resources, selecting demand-side power supply resources to be utilized, based on power supply resource-related information for each of available demand-side power supply resources, which is received from the providing side, and notifying the selection results to the selected demand-side power supply resources.
