Abstract:
모바일 단말의 무선 통신을 통해 발생하는 패킷을 수집하여 트래픽을 분석함으로써 모바일 단말에서 처리하는 기본 서비스를 파악하고, 로컬 네트워크 상에 등록된 장치를 제어하여 기본 서비스의 효용에 도움을 주는 서비스모듈을 실행한다. 이러한 기본 서비스의 효용에 도움을 주는 서비스모듈을 기 설정된 데이터베이스를 이용하여 검색하고, 로컬 네트워크 상의 현재 장치의 상태정보를 점검하여 서비스모듈을 결정한다. 무선 패킷의 트래픽 정보를 이용함으로써 가용 자원의 활용가능성을 높이고 자동으로 간접 서비스를 제공 할 수 있도록 유비쿼터스 환경을 구현한다.
Abstract:
PURPOSE: A service resuming method of a network based mobility management system is provided to maintain services in a mobility management system by correcting distributed intelligence. CONSTITUTION: Binding information is received from MICS(Mobility and Information Control Server). An MBT(Mobile node Binding Table) is updated. A mobile node constructs a tunneling with opponent nodes. When the MICS process is restarted(470), a fault state flag is read. An error state is determined. Binding information is received from HCA(Handover Control Agents). A GBT(Global Binding Table) is updated.
Abstract:
PURPOSE: A wireless connection apparatus, L2 switch, and multicast handover support method using the same are provided to support multicast handover between cells of a mobile node within a second layer network apparatus based on a mobile wireless communication network. CONSTITUTION: A handover management unit(124) manages MAC address information of a mobile node which contacts to a wireless communication network. The handover management unit manages group information and a multicast service source for a multicast service. The multicast service is provided to the mobile node. The handover management unit interlocks with an L2 switch. The handover management unit supports multicast handover between cells of the mobile node by providing the information to the L2 switch.
Abstract:
본 발명은, 호스트 식별 프로토콜(HIP: Host Identity Protocol)의 확장으로 유비쿼터스 네트워크 환경에서 모든 객체(object)들을 구분하여 통신 서비스를 제공하는 시스템 및 방법에 관한 것으로, 복수의 객체들이 호스트에 접속하면, 상기 호스트가, IP 네트워크 상에서의 상기 객체들의 위치를 확인하고, 상기 객체들의 위치에 따라 서로 다른 방식으로 상기 객체들과의 바인딩을 수행하며, 상기 바인딩을 통해 HIP를 확장하여 상기 HIP의 헤더에 상기 호스트의 식별자 및 상기 객체들의 식별자를 포함시킨 후, 상기 HIP의 헤더를 포함한 페이로드 패킷을 정보 서버로 전송하며, 상기 객체들과 통신을 수행하고자 하는 클라이언트가, 상기 호스트 및 상기 객체들의 정보를 상기 정보 서버로 요청하고, 상기 요청에 상응하여 상기 정보 서버로부터 상기 호스트의 식별� � 및 상기 객체들의 식별자를 수신하고, 상기 수신한 식별자들을 이용하여 상기 객체들과 경로를 설정한 후 상기 객체들과 직접 데이터 통신을 수행한다.
Abstract:
PURPOSE: An IPTV service method and system using a satellite are provided to reduce transmission delay in case of offering the service of a terrestrial network IPTV system through the satellite. CONSTITUTION: A classifer(220) offers the index value of a sub proxy corresponding to a data packet. In case the sub proxy corresponding to the data packet does not exist, a manager(230) creates the sub proxy corresponding to the data packet. According to the presence of the sub proxy corresponding to the data packet of a service provider, a main proxy controller(210) executes the classifer or the manager. The main proxy controller transmits the generated ACK of an ACK generator(242) to a terminal.
Abstract:
PURPOSE: An apparatus and a method for registering an enabler in a service transmission platform are provided to extend a function of a service transmission platform by newly adding interface which is not supported in a current enabler. CONSTITUTION: An authentication processing unit(200) authenticates a service user(100) which uses an enabler and provides the information of the enabler to the service user which is allowed to the information according to a service convention. The service user registers a new enabler. The authentication processing unit re-authenticates the registration for preventing the indiscreet registration of the enabler. An enabler management unit(201) provides and manages information about the enabler provided from the service transmission platform. An interface management unit(202) manages an interface provided from the enabler.
Abstract:
A method and system for bundled authentication of wired or wireless terminal between the service and access networks in NGN environment are provided to reduce the curriculum of additionally inputting password by performing the NACF-SCF bundle authentication regardless of wireless and wired access. An NGN terminal unit(10) comprises a WLAN(Wireless LAN) terminal(101), a WiBro terminal(102), and a cable terminus(103) and a ADSL (Asymmetric Digital Subscriber Line) terminal(104). A connection unit(11) is used for the packet connection of the NGN terminal. An AP (Access Point)(111) is connected to the WLAN terminal. A RAS (Remote Access Server)(112) is connected to the WiBro terminal. A CM (Cable Modem) part(113) is connected to the cable terminus. The CM part is formed with CM and CMTS(Cable Modem termination System). The ADSL terminal is connected to wired and wireless network(16) through the ADSL circuit. A NACF(Network Attachment Control Functions)(12) assigns the connection internet protocol address. The NACF part performs the access authentication. A SCF(Service Control Function)(13) which is the service control network performs the service routing and service certification. A bundle authorization control server(14) performs the exchange of the authentication information between the NACF part and the SCF part.
