Abstract:
An apparatus and a method for supporting network-based mobility for dual stack terminals are provided to connect data transmitted to a GMAP(Global Mobility Anchor Point) through IPv6(Internet Protocol version 6)-in-IPv4 tunneling or IPv4-in-IPv6 tunneling to an MAP, so that communication with an external terminal can be possible even when the dual stack terminal moves to an another network such as an IPv4-only network or an IPv6-only network. An MAP(Mobility Anchor Point) device(210) for supporting mobility of dual stack terminals comprises a storage(211) and a transmitter(212). The storage stores information about the dual stack terminal after movement and information about an access router to which the dual stack terminal belongs. The information is received from a first MAP(220) as a movement support anchor at another network to which the dual stack terminal has moved. When data to be transmitted to the dual stack terminal is received, the transmitter transmits the data to the first MAP based on the binding information on the dual stack terminal stored in the storage.

본 발명은 듀얼 스택 단말을 위한 망 기반 이동성 지원 장치 및 그 방법에 관한 것으로, 상세하게는 듀얼 망에서 IPv4 망 또는 IPv6 망으로 이동한 듀얼 스택 단말의 바인딩 처리 및 데이터 전송을 위한 MAP(Mobility Anchor Point) 장치와 그 구현 방법에 관한 것이다. 차세대 인터넷 프로토콜인 IPv6가 망에 적용되기 시작하면 IPv4와 IPv6 모두를 지원하는 듀얼 스택 단말이 도입될 것이며 이러한 듀얼스택 단말의 이동 환경시에는 IPv4/IPv6 듀얼 망뿐만 아니라, IPv4 전용망 혹은 IPv6 전용망으로의 이동이 고려될 것이다. 본 발명에서는 종래 망 기반 이동성 지원 방법에 사용되는 이동 지원 앵커(MAP)를 확장하여, IPv4 전용망 혹은 IPv6 전용망과 같은 서로 다른 망-기반 지역 이동성 지원 도메인 (Network Localized Mobility Management Domain) 사이의 이동시 두 MAP 사이에 바인딩 관리 메시지를 주고 받게 함으로써 두 MAP간에 IPv6-in-IPv6 터널 혹은 IPv4-in-IPv6 터널을 설정되게 하여 듀얼 스택 단말이 IPv4 전용망 혹은 IPv6 전용망으로 이동하는 경우에도 외부 단말과의 통신을 가능하게 한다. 듀얼 스택 단말, MAP(Mobility Anchor Point), 이동성 지원, IPv4, IPv6
Abstract:
non-3GPP 액세스를 사용하여 SNPN과 PDU 세션이 설정되어 있는 UE에 관한 분석 정보를 PLMN의 NWDAF로부터 수신하는 단계, 분석 정보를 바탕으로 UE가 PLMN에서 SNPN으로 이동할 것으로 판단하는 단계, 그리고 판단에 기반하여 SNPN PDU 세션을 위한 액세스를 non-3GPP 액세스에서 3GPP 액세스로 변경할 것을 UE에게 지시하는 단계를 통해 PLMN과 SNPN 사이에서 이동하는 UE의 서비스 연속성을 지원하는 방법이 제공된다.
Abstract:
Disclosed is a device and method to monitor a network and inspect a packet, and perform a packet inspection and a real-time network monitoring function in a network system. According to the present invention, the device to monitor a network and inspect a packet includes: a controller which receives and transmits an open flow protocol message, and controls a network; a flow table to transmit data; and a switch retaining a security channel for connection with the controller. The flow table includes information on a flow on which a user desires to perform monitoring or packet inspection.
Abstract:
PURPOSE: An apparatus for constructing a virtual dedicated network and method thereof are provided to guarantee network features during fixed period by utilizing one or more platform resources according to the interworking policy of a platform. CONSTITUTION: When a user terminal is connected, a virtual network connecting port(210) creates a virtual network profile reflected from features of desired virtual dedicated networks. A virtual network management unit(230) creates virtual dedicated network based on the virtual network profile. The virtual network management apparatus requests a detailed interworking process of the virtual dedicated network. A network interworking control apparatus(220) allocates physical resources and virtual resources to components specified in the virtual network profile.
Abstract:
PURPOSE: A virtualization support programmable platform apparatus and packet transfer method are provided to identify a virtual interface which is connected to an ID of a sliver by using a programmable platform or a router. CONSTITUTION: A sliver communications unit(100) transmits and receives a packet with a sliver which is generated for the support of a future internet test. A header insertion unit(110) includes destination location sliver identifying information which is requested from a sliver and a test bed header including virtual interface identifying information. A virtual LAN field processing unit(130) removes an encapsulated part from a VLAN tag in order to transfer a packet through a virtual LAN. A network communication unit(120) transmits a test bed header in the header insertion unit that is transmitted through the network.
Abstract:
A BS(Base Station) apparatus and a method for IP(Internet Protocol) multicast group join message flooding avoidance in a portable Internet network are provided to reflect a temporal gap using a delay timer in the portable Internet network having point-to-multipoint characteristics, thereby preventing excessive distribution of multicast group join messages. A BS(Base Station) apparatus for IP(Internet Protocol) multicast group join message flooding avoidance in a portable Internet network comprises the followings: a receiver(221) for receiving a join message for a group from a first subscribe station(200) which wants to join the IP(Internet Protocol) multicast group; and a transmitter(222) which transmits the received join message for the group to other subscribe station(210,250) which belonging to the BS, and transmits the received join message for the group to an access router(230) to which the BS belongs and other BSs(240) which belong to the access router when the join message for the group is not received from a second subscribe station during a set time after the receiver receives the join message for the group from the first subscribe station.
Abstract:
PURPOSE: An IPv6 Internet address automatically generating method and lookup method using a phone number are provided to allow a phone terminal user to easily access the Internet by using a phone number which has been assigned and conveniently used when an IP protocol is mounted at a phone terminal so as to be used as a host for using an Internet service, and obtains an IP address by generating an IP address of the phone terminal on the basis of a phone number so as for the phone terminal to be operated as a transmitter in an IPv6 communication environment. CONSTITUTION: An IPv6 protocol engine reads a phone number of a terminal(S41). Each decimal number is made to 4 bit binary form by using the phone number constructed as an E.164 form(S42). Since the binary bit stream has the maximum 60 bits or below, a padding operation is performed to add '0' to upper bit digits until it becomes 64 bits from the created bit stream(S43). A 64 bit phone number interface ID is combined with prefix information assigned in an IPv6 protocol operation(S44). An automatic generation of an IPv6 unicast address is completed(S45), and an Internet host transmits an IP packet by using the address.
