Abstract

IMS(IP Multi-Media Subsystem) is in the limelight as the Integrated wire and wireless Systems because of a sudden increase of smart mobile devices and growth of multimedia additional services such as IPTV. The structure of IMS is designed as a session control layer to provide various multimedia summative service using SIP based on IP communication network in order to carry out set-up, change and release by NGN of course, the existing voice services. But now It is broadly substituting in the IPTV, wire phone company and it is substituted in internet platform base on the soft-switch in currently. Especially, in currently, 4G LTE in a mobile communication company is rapidly growing in market. Therefore, in this study, we had designed and developed to the main prosser that can admit to 1000 user over and SIP gateway which can link the IMS Core that can link SIP Device which adopt the standard protocol on the SIP and to provide variable multimedia services.

지능형 모바일 단말기의 급증과 IPTV등 다양한 멀티미디어 부가 서비스의 증가로 IMS(IP Multi-Media Subsystem)가 유/무선 통합 제어 망으로 각광을 받고 있다. IMS의 구조는 인터넷 프로토콜(IP) 기반의 통신망에서 기존 음성 서비스는 물론 SIP를 이용한 다양한 멀티미디어 부가 서비스를 제공하기 위해 세션의 설정 변경 및 해제를 수행하도록 NGN에서 세션 제어계층으로 정의 되었다. 현재는 IPTV 유선전화서비스 사업자 등에서도 폭넓게 채택되어 기존 소프트스위치 기반의 인터넷전화 서비스 플랫폼을 대체하고 있고 특히, 최근에는 이동통신서비스인 4G LTE의 확산에 따라 관련 시장이 빠르게 성장하고 있다. 따라서 본 논문에서는 1,000 회선급 가입자 회선을 수용 할 수 있는 고속의 메인 Processor와 기존 표준 SIP 프로토콜을 사용하는 SIP 단말과 IMS Core와 연동 할 수 있고 다양한 멀티미디어 서비스를 제공할 수 있는 SIP 게이트웨이를 설계하고 구현하였다.
