Abstract: A method for establishing a control tunnel and a direct tunnel in an IPv4 network-based IPv6 service providing system is provided to easily induce spreading of IPv6 application services which have not activated yet by performing IPv6 communication. When a terminal(10) receives a tunnel response message from a control server(30) by using service information downloaded from a portal server(20) in its initialization, it establishes a control tunnel with the control server. The terminal transmits a registration request message to the control server via the established control tunnel. When the terminal receives a registration response message from the control server, it provides information about establishment of the control tunnel and registration completion. The terminal periodically checks whether IPv6 data can be transmitted or received through the control tunnel established with the control server. The terminal periodically transmits/receives an update message for updating its existence time to/from the control server.

Abstract: 본 발명은, IPv4 네트워크 기반 IPv6 서비스 제공 시스템에서의 제어 터널 및 다이렉트 터널을 설정하기 위한 방법에 관한 것으로서, IPv6 서비스를 제공하기 위해 초기화 시 상기 포털 서버로부터 다운로드 받은 서비스 정보를 이용하여 상기 제어서버로 터널 요청 메시지를 전송한 후 상기 제어 서버로부터 터널 응답 메시지를 수신하면, 단말이 위치하는 네트워크에 따라 상이한 타입으로 상기 제어 서버와의 제어 터널을 설정 및 등록을 수행하고, 상기 제어 터널 설정 과정에서 획득한 단말 정보 즉, 네트워크 위치 정보 및 상태 정보를 이용하여 상대 단말과 다이렉트 터널 요청 및 응답 메시지를 송수신하여 다이렉트 터널을 설정함으로써, IPv4 기반의 IPv6 터널링을 사용하여 IPv6 통신을 하기 때문에 현재 활성화 되어 있지 않은 IPv6 응용서비스들의 확산을 쉽게 유도할 수 있으며, 기존의 네트워크 장비를 변경하지 않고 각 단말과 제어서버의 소프트웨어만 변경하면 되므로 서비스 제공자의 비용 부담을 최소화할 수 있는 효과가 있다.
