초록

스마트폰, 태블릿 PC, 넷북 등의 지능형 이동식 단말기 사용자의 급증과 IPTV와 같은 응용 서비스의 발전으로 멀티미디어 기반 응용 서비스의 수요가 증가하고 있다. 네트워크 자원이 한정되어 있는 상황에서 한정된 자원을 적절하게 조절하기 위한 다양한 정책들이 제안되고 있다. 사용자의 요구에 적합한 멀티미디어 서비스 제공을 위하여 IMS(IP Multimedia Subsystem)가 유무선 통합 제어망으로 각광을 받고 있으며, IMS의 PDF(Policy Decision Function)를 적용한 정책 기반 모델이 등장하고 있다. 본 논문에서는 IMS의 PDF에서 다양한 프로토콜을 적용한 QoS(Quality of Service) 적용 모델과 이를 이용한 사용자 시나리오를 제안한다.

The need of multimedia based application service is increasing as the number of smart mobile devices such as smart phone, tablet PC, and netbook is increasing rapidly and the development of application service like IPTV. There are various proposed policies to control the limited network resources. The IMS is used to control wired and wireless aggregation network to support multimedia services that are suitable to the user's need and the policy based models using the PDF of the IMS have emerged. In this paper, we propose the QoS adaption model using various protocols with the PDF of the IMS and the user scenario.
