摘要:
A system and method for transmitting/receiving a call on a home network. When a request for call transmission/reception is made, a CP selects a target electronic device to/from which to transmit/receive a call from among at least one electronic device, establishes a connection for call transmission/reception between a terminal and the selected target electronic device, and controls the call transmission/reception between the terminal and the selected target electronic device.

Provided are a method and apparatus for generating a mashup graph. The method includes receiving a set of services and collecting application programmable interfaces (APIs) of the services, and generating a mashup graph by using the collected APIs according to information regarding connections between the APIs and weights between the APIs. Thus, a mashup graph having a simple form in which a user's preference can be reflected can be generated, instead of a complicated connection matrix.

An event message transmitting method performed in a controlled device (CD) which is controlled by a control point (CP) is provided, in which an application is received from the CP via a network according to a network protocol, the received application is installed according to a framework of an execution environment of the CD, a first event message that represents a state change of the application is generated according to the framework, and the first event message is converted into a second event message that conforms to the predetermined network protocol. Accordingly, information about a state change of a CD which operates in an execution environment can be adaptively transmitted according to a network protocol.

Provided are a method and apparatus for discovering a Universal Plug and Play (UPnP) device by using resource information. The method includes: multicasting a search message including resource request information, which requests a resource to the device, to a network complying with the predetermined standard; receiving at least one response message regarding the search message; and discovering a device corresponding with the resource request information based on the received response message. Accordingly, available information of the resource can be obtained in a discovery process, and as a result, a trial and error during the search and control can be avoided. Also, unnecessary waste of resources, such as network traffic, can be prevented, and thus efficiency of a communication protocol is improved.
摘要:
A method of processing an action executes an action requested by a control point for controlling a controlled device through a network, stores a result of executing the action as a pending result of the action when a network connection between the controlled device and the control point is terminated, and transmits the stored pending result of the action to the control point when the network connection between the controlled device and the control point is resumed.
摘要:
Provided is a method for synchronizing contents included in devices in a Universal Plug and Play (UPnP) network. A control point device, which contains local content but cannot provide a content directory service, converts information regarding content objects of the control point device into Digital Item Description Language Lite (DIDL-Lite) format, and manages a mapping table, thereby performing synchronization with a device such as a UPnP media server providing a content directory service, without loading a separate protocol stack.
摘要:
A method of synchronizing a plurality of content-directory service (CDS) devices is provided. The method includes retrieving and discovering N CDS devices in a home network by a control point (CP), transmitting a StartSync message that requests the start of synchronization to a certain CDS device of the N CDS devices by the CP, forwarding a StartPeerSync message that informs remaining N-1 CDS devices of the fact that synchronization will be started by the CDS device that has received the StartSync message, and synchronizing each of the N CDS devices with the remaining N-1 CDS devices, in a home network that includes N CDS devices that provide metadata of multimedia content existing in the home network, and the CP that receives metadata from the N CDS devices and requests the media renderer to replay the multimedia data.
摘要:
A system and method for establishing a secured connection between home network devices are provided. Particularly, a system and method for establishing a secured connection between a home network including a plurality of non-secured Universal Plug and Play (UPnP) devices and a secured external UPnP device by creating virtual UPnP devices for the respective corresponding non-secured UPnP devices are provided. The system for establishing a secured connection between home network devices includes a virtual UPnP device creation unit which creates a secured virtual UPnP device for a non-secured UPnP device, an information storage unit which stores correspondence information regarding the non-secured UPnP device and the virtual UPnP device, and a secured communication unit which securely communicates with a secured UPnP device with reference to the correspondence information.
摘要:
An apparatus and method for sharing services on a network wherein a role is decided for sharing services so that the services can be shared between OSGi service platforms of devices operating on a desired network using a desired election algorithm. The apparatus for sharing the services on the network includes a service role configuration unit for deciding a service role to share a desired core service through the election algorithm when connected to the desired network; and a service request processing unit for processing and requesting the core service requested to support a desired service from the OSGi service platform of a device assigned externally, according to the service role decided by the service role configuration unit.
