Abstract
Description
Claims (3)
- VoIP와 NAT-PT 기반 변환/라우팅 서비스가 통합 솔루션으로 제공되는 환경에서 서로 상이한 IP 프로토콜 기반의 송/수신자 단말, 게이트키퍼 서버간에 교환되는 H.225.0 메시지와 H.245 메시지의 NAT-PT 주소 변환이 동적으로 이루어 질 수 있도록 게이트키퍼와 NAT-PT를 연동하는 방법에 있어서,게이트키퍼와 NAT-PT 라우터 사이에 주소 변환을 위한 정보 교환용의 채널을 여는 제 1단계;게이트키퍼가 H.225.0 RAS 시그널링 단계에서 IPv6 망에 있는 단말의 IPv6 주소 정보를 알려주는 제 2단계;NAT-PT 라우터가 게이트키퍼로부터 IPv6 주소 정보를 받았을 때 IPv4 주소를 할당하여 게이트키퍼에게 알려주는 제 3단계;게이트키퍼가 할당받은 IPv4 주소정보를 반영하여 IPv4 망에 있는 IPv4 단말로 향하는 H.224.0, H.245 메시지를 재 생성하는 제 4단계;호가 종료될 때, 게이트키퍼가 NAT-PT 라우터로부터 할당받은 NAT-PT 자원을 NAT-PT 라우터에게 반환하는 제 5단계로 구성된 것을 특징으로 하는 게이트키퍼와 NAT-PT 연동을 위한 서로 상이한 IP 주소 연동 방법.
- 제 1항에 있어서,상기 IPv6 망내에 위치한 내부 수신자 단말이 내부에서 외부로 통화를 시도하는 경우, 시그널링 메시지의 IPv6 송신원 주소 정보 자체를 내부 단말의 IPv6 주소로 확보하여 NAT-PT 라우터로 전송해 주는 것을 특징으로 하는 게이트키퍼와 NAT-PT 연동을 위한 서로 상이한 IP 주소 연동 방법.
- 제 1항에 있어서,상기 IPv4 망내에 위치한 외부 송신자 단말이 외부에서 내부로 통화를 시도하는 경우, 시그널링 메시지의 페이로드 내에 수신자 전화번호가 있으므로 게이트키퍼에서 수신자 전화번호에 해당하는 IPv6 주소를 찾아서 해당 IPv6 주소를 NAT-PT 라우터에 전달하는 것을 특징으로 하는 게이트키퍼와 NAT-PT 연동을 위한 서로 상이한 IP 주소 연동 방법.
