Abstract

We can use NAT(Network Address Translation) technology to solve the lack of IP address. The problem of NAT traversal is happened when the filtering characteristics of NAT remove the packet that has no binding in the address translation table of NAT. There were many kinds of way to solve these problems by using additional device. Lately, network market is changed into integrating wired and wireless network by the IMS(IP Multimedia Subsystem). The IMS integrates to control network of wired and wireless network, has emerged to control convergence network effectively. Lately, the additional devices like IBCF(Interconnection Border Control Function) and IBGF(Interconnection Border Gateway Function) are used to solve the NAT traversal problem in the IMS. In this paper, we propose the solution of NAT traversal using P-CSCF without any additional equipment in the IMS.

IP 주소 공간의 부족 문제를 해결하기 위해 NAT(Network Address Translation) 기술을 활용할 수 있다. NAT의 주소 변환 테이블에 없는 바인딩과 관련된 패킷을 제거하는 필터링 특성 때문에 NAT Traversal 문제가 발생한다. 이러한 문제를 해결하기 위해 부가적인 장비를 활용한 여러 가지 방법들이 제시되었다. 최근의 네트워크 시장은 유선과 무선이 통합되는 형태로 발전하고 있으며, 이를 효과적으로 제어하기 위하여 IMS(IP Multimedia Subsystem)라는 유무선 통합 제어 망이 등장하였다. IMS에서 IBCF(Interconnection Border Control Function)와 IBGF(Interconnection Border Gateway Function)라는 부가적인 장비를 이용하여 NAT Traversal 문제를 해결하고 있다. 본 논문에서는 P-CSCF(Proxy-Call Session Control Function)를 활용하여 부가적인 장비를 사용하지 않고 NAT Traversal 문제를 해결하는 방안을 제안한다.
