Abstract:
본 발명은 UPnP 네트워크에서 디바이스들이 보유하고 있는 컨텐트를 동기화하는 방법에 관한 것으로, 로컬 컨텐츠를 보유하고 있으나 컨텐트 디렉토리 서비스를 제공할 수 없는 컨트롤 포인트 장치가 자신의 컨텐트 오브젝트들에 관한 정보를 DIDL-Lite 포맷으로 변환하고, 그에 대한 매핑 테이블을 관리함으로써 별도의 프로토콜 스택을 탑재하지 않아도 UPnP 미디어서버 등과 같이 컨텐트 디렉토리 서비스를 제공하는 디바이스와 동기화를 수행할 수 있다.
Abstract:
PURPOSE: An apparatus and a method for supplying a Wi-Fi direct connection based UPnP service are provided to confirm URI(Uniform Resource Indicator) information for controlling a terminal in a process for searching for a device of a Wi-Fi MAC(Media Access Control) layer. CONSTITUTION: A message receiving unit(206) receives a response message. The response message includes UIR information of a controlled terminal. A message analyzing unit(208) obtains URI information. The URI information is included in the response message. A service controlling unit(210) performs a UPnP service function based on WiFi direct connection.
Abstract:
PURPOSE: A call method using a home network and a device thereof are provided to eliminate a security problem due to exchange of high quality images that a UPnP telephony service suggests without damaging UX(User Experience). CONSTITUTION: A control point module transmits an address request message about a REST server through an SMS(Short Message Service) transmitting/receiving module to a second mobile communication terminal(503). The control point module transmits an address response message to a first mobile communication terminal through the SMS transmitting/receiving module(505). The address response message includes the URI(Uniform Resource Identifier) address of the REST server. If the phone number of device detection request/device control messages is the same as the phone number of the first mobile communication terminal, the control point module transmits a response message including device list/device control events to the first mobile communication terminal through the REST server and a client(507,509).
Abstract:
PURPOSE: A call method using a home network and a device thereof are provided to authenticate a device for requesting an access to the home network when a home network telephony service is provided. CONSTITUTION: When a home network device list response message is valid, a first mobile communication terminal selects a first television device(817). When the phone number of a call start request message is the same as the phone number of the first mobile communication terminal, a second mobile communication terminal selects a second television device(825,827). The second mobile communication terminal transfers the address of the first television device to the second television device(829). The first and second mobile communication terminals arrange calls(835).
Abstract:
PURPOSE: An energy profile establishment method and system are provided to enable a user to conveniently use an energy profile by automatically updating the energy profile. CONSTITUTION: If energy profile version information does not support an HEMS(Home Energy Management System), the HEMS transmits a profile update request message to a home network apparatus(503, 505). The home network apparatus downloads an energy profile from a download server(511). The home network apparatus updates the existed energy profile(513).
Abstract:
PURPOSE: A method and an apparatus for restricting disclosure of network information during a remote access service are provided to change the publication for the information of a network apparatus which filter change of an RA service apparatus in the change of external information for an additional and existing home network apparatus. CONSTITUTION: An RA(Remote Access) service apparatus sets up a UPnP(Universal Plug and Play) virtual device(710), and registers at least one device for the external publication among searched physical devices as a virtual device or the embedded device of the virtual device(720). The device sets the filtering of a service and home network device from a user(730), and obtains device description documents(740). In addition, the device transfers a URL(Uniform Resource Locator) to a remotely-connected external network(750).
Abstract:
PURPOSE: An IP address collision problem solving method and a device thereof are provided to prevent the collision due to same IP addresses between a remote network device and a device which is connected to a remote access server. CONSTITUTION: A remote access client(3100) collects the list of IP addresses which are used in a network where the client is included and transmits an IP address list to a remote access server(3200). The remote access server collects the list of an IP address which is used in a network where the server is included and receives the IP address list of the remote access client. The remote access server compares two IP address lists. When a collision is generated, the remote access server newly assigns an IP address of an UPnP(Universal Plug and Play) device where a collision is generated.
Abstract:
PURPOSE: A system for receiving and transmitting room number on home network using an adjacent home network device is provided. CONSTITUTION: A system for receiving and transmitting room number on home network comprises: a telephony terminal(2103) which controls room number by receiving or transmitting room number; at least one electronic device(2104) which receives or transmits the room number from or to telephony terminal; and an UPnP(Universal Plug and Play) telephony control point(2102) which selects subject electronic device and telephony terminal. The UPnP(Universal Plug and Play) telephony control point sets the connection for receiving and transmitting room number between the telephony terminal and subject electronic device.
Abstract:
PURPOSE: An apparatus and a method for sharing a bookmark in a home network are provided to make a new service by sharing a bookmark with another user. CONSTITUTION: A home network device of a bookmark generator designate a meta data value of a bookmark(512), and a transmit the bookmark to an IPTV(Internet Protocol TV) service provider(516). In addition, home network device requests the bookmark from the IPTV service provider(518,520). The IPTV service provider selects an effective bookmark, and transmit the response to the home network device of the book mark sharer(522-526).
Abstract:
PURPOSE: A UPnP(Universal Plug and Play) apparatus for resolving network address collision to consider remote access and a method thereof are provided to enable an RAS(Remote Access Server) device to connect an UPnP device of a home network remotely even when the UPnP device of a remote network has an IP address identical to that of the UPnP device of the home network. CONSTITUTION: A UPnP(Universal Plug and Play) RAS(Remote Access Server) device of a home network includes an address selector(410) of a virtual home network and a conversion unit(420). The address selector selects an address of a virtual home network for the remote connection which is not collided with an address of a remote network. The conversion unit converts network and virtual network addresses to each other in the packet transmitted and received between the remote network and the home network.
