    摘要： The present invention relates to a method and apparatus for performing IPv6 over IPv4 transition to improve performance of a control server. When an edge router selected by the control server according to a tunnel creation request of an IPv6 terminal receives a tunnel creation request message from the control server, the edge router transmits a tunnel creation response message for the received tunnel creation request message to the IPv6 terminal through the control server, and the edge router performs IPv6 over IPv4 transition through a tunnel created by the IPv6 terminal that received the tunnel creation response message so as to improve the performance of the control server. Therefore, loads of the control server occurred because all terminals set control tunnels to the control server can be prevented, and service extensibility due to the increase in the number of subscribers can be guaranteed.

    摘要： Technology for forming a virtual private network (VPN) is provided. A VPN gateway that supports mobility with a connection node having a virtual home address (HoA) and a care of address (CoA) includes a mobility support unit, a data security unit, and a virtual address converter. When a packet is transferred from the connection node, the mobility support unit sustains a binding relationship between a home address (HoA) of the connection node and the changed CoA, and processes a mobility tunnel for the packet, thereby generating a first conversion packet. The data security unit performs a security test of the first conversion packet. The virtual address converter converts the HoA of the connection node, which is a source address of the first conversion packet in which the security test is complete, to a private network internal address that can be used in the VPN, thereby generating a second conversion packet.

    摘要： Provided is a method for configuring a control tunnel and a direct tunnel in an IPv4 network-based IPv6 service providing system. To provide IPv6 service, when a random request terminal receives a tunnel response message from a control server by using service information downloaded from a portal server at the time of initialization, the request terminal configures a control tunnel with the control server, and is registered to the control server. The request terminal transmits and receives a direct tunnel request message and a direct tunnel response message with a counterpart terminal by using its terminal information learned during the control tunnel configuration, i.e., network position information and status information, thereby configuring a direct tunnel. Thus, IPv6 communication is made through IPv4 based IPv6 tunneling, so that IPv6 application services that are not yet widely used can easily come into wide use. Also, only software change of each terminal and a control server is required without changing existing network equipment, so that a cost burden of a service provider can be minimized.

    摘要： The invention relates to a method and an apparatus for controlling seamless handover between heterogeneous networks based on IPv6 over IPv4 tunneling. When IPv6 service is provided using tunneling in an IPv4 based network environment, handover of a mobile terminal between different networks is achieved through switching of an active tunnel and a standby tunnel, and thus handover between different networks is facilitated and data loss is prevented to secure continuity of service provided to the mobile terminal even when the mobile terminal hands over to a heterogeneous network.
