How to set up a direct tunnel and control in tunnel IPv6 service providing system of the IPv4 network-based

摘要

The present invention relates to a method to set up a direct tunnel and control in an IPv6 tunnel service providing system based on the IPv4 network. In order to provide IPv6 services, by using the service information that is downloaded from the portal server during initialization, receiving a tunnel response message from the control server, and sets a control tunnel with the control server, a random request terminal, wherein It is registered with the control server. By sending and receiving the messages and responses direct tunnel request with the other terminal by using the status information and the position information of the network that is the terminal information of its own learned in the process of setting the control tunnel, the request terminal, a direct tunnel setting. In order to perform IPv6 communication using the IPv6 tunneling IPv4-based in this manner, without having to be able to easily induce the diffusion of IPv6 application services that are not activated at present, to change the network existing equipment, the it is sufficient only change the software of the control server and the terminal, there is an advantage of being able to minimize the costs of the service provider.
