Disclosed are a communication scheme and a system thereof for converging an IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. A method and an apparatus for configuring a connection with a second device, which provides access to a network, by a first device in a communication system, is provided. The method includes discovering the second device supporting a neighbor awareness network (NAN) and located within a predetermined range from the first device, exchanging an ephemeral key of the first device for identifying the first device and an ephemeral key of the second device for identifying the second device, and performing a secure connection between the first device and the second device.

Method and apparatus for configuring connection between devices in communication system

The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a higher data transmission rate than a 4G communication system such as LTE. An embodiment of the present disclosure relates to a method in which a plurality of devices use a service linked to a first device, the method comprising the steps of: performing a connection to a central display device, and mirroring the service to the central display device on the basis of a playlist of services stored in the first device; receiving, from a second device, a change request for the playlist, and updating the playlist to correspond to the change request; and transmitting information related to the updated playlist to the central display device.

Method and apparatus in which a plurality of electronic devices use service linked to one electronic device

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.

Method and device for executing object on display

A method of giving a monopoly of a call in a call transmission/reception system using UPnP (Universal Plug and Play) includes a telephony server setting a user's authority to manage a session when the telephony server generates the session; the telephony server performing a user authentication when the telephony server receives a call for an action for managing the session from a control point; and the control point performing the action for managing the session if a user of the control point has an authority to manage the session as the result of authentication.

Method and apparatus for giving monopoly of call in call transmission/reception system using UPnP

The present disclosure provides a method for performing initial setup with a connection acceptance device by a connection request device, the method comprising the operations of: performing an association procedure with a configurator; transmitting a first probe request message to the configurator; receiving a first probe response message including information required for a connection to the connection acceptance device from the configurator; driving a timer and transmitting a second probe request message to the connection acceptance device; receiving a second probe response message from the connection acceptance device; and starting a secure connection to the connection acceptance device when the second probe request message is received before the timer has expired, and information included in the second probe response message coincides with the information required for the connection, which is included in the first probe response message.

Technique for supporting initial setup between connection request device and connection acceptance device

A method for communicating between devices is presented. The method includes dividing a first public key of a first device into at least two partial keys, transmitting the at least two partial keys through at least two communication channels having different physical characteristics, receiving a second public key of a second device through at least one of the at least two communication channels, authenticating the second device based on the received second public key, and performing secure communication with the second device using a public key generated based on the received second public key.

Method and apparatus for proximal authentication of wireless electronic device

Provided is a method and apparatus for wirelessly transmitting Universal Serial Bus (USB) application data by using an Enhanced Distributed Channel Access (EDCA) scheme that uses one or more Access Channels (ACs) having different priorities. The method includes receiving one or more USB application data from an USB application, dynamically assigning an AC through which the USB application data is to be transmitted, and transmitting the USB application data through the assigned AC.

Scheme for supporting wireless transmission taking into account QoS of USB application data

A method and apparatus for transmitting, receiving, and storing files based on a predetermined container structure are provided. The method includes identifying some or all of files to be transmitted among the stored files; generating transmission information for the identified files and transmitting the transmission information to the receiving device; configuring a header including information about the location of the directory in which each of the identified files is to be stored; and adding the configured header to each of the identified files and transmitting the header-added files to the receiving device.

Apparatus and method for transmitting and receiving files in general purpose device

A method and apparatus for playing back a scene using Universal Plug and Play (UPnP). A control point sends a request for a scene to be played back to a media server that stores Audio/Video (AV) content and receives the scene to be played back from the media server in response to the request. The control point receives information about supportable protocol and file format from a media renderer that will play back content, and determines a content resource, a protocol and a file format to be used for playback based on the information. The control point composes a scene to be played back based on the received scenes. The media renderer plays back the composed scene.

Method and apparatus for playing back scene using UPnP

Provided is a method and system for synchronizing a plurality of content directory service (CDS) devices in a home network environment. The method of synchronizing the plurality of CDS devices of a home network, which includes the plurality of CDS devices and a control point (CP), comprises (a) requesting a first CDS device among the plurality of CDS devices to start synchronization using the CP; (b) performing the synchronization with a second CDS device among the plurality of CDS devices using the first CDS device; (c) selecting a third CDS device from the plurality of CDS devices and requesting the third CDS device to start synchronization with the first CDS device or the second CDS device using the CP; and (d) performing the synchronization with the first CDS device or the second CDS device using the third CDS device.

Method of synchronizing a plurality of content directory device (CDS) devices, CDS device, and system

A method is provided for resolving a collision of Internet Protocol (IP) addresses between devices connected to a first server and a second server remotely accessed in a Universal Plug and Play (UPnP) remote access service. The second server receives address information of a network of the first server from the first server. The second server compares address information of a network of the second server with the received address information of the network of the first server, and determines whether a collision has occurred between addresses of the first server and the second server. A collided address is changed when the collision has occurred.

Method and apparatus for resolving IP address collision in remote access service

The present disclosure provides a method for managing buffers of a device for Universal Serial Bus (USB) communication in a wireless environment. The method includes determining respective current data storage levels of transmit buffers that store different types of data for USB communication; comparing the respective current data storage levels of the transmit buffers with corresponding respective predetermined threshold levels; and controlling an input rate or output rate of a first transmit buffer if it is determined based on the comparison that the first transmit buffer has a current data storage level that exceeds a predetermined threshold level.
