Abstract

For supporting various mobile networks, this paper proposes a framework of distributed connection admission control, named SmartCAC. Especially, intelligent CAC operations are adopted in terms of interoperation between mobile nodes and mobile networks. This scheme does not need to correct information between networks. Basically vertical handover call can use guard channel that was reserved for handoff, because SmartCAC addresses the identification between vertical handover call and new call, delay and reliability as requirement of QoS for efficient connection control. The scheme also uses mobile terminal speed for network filtering. Especially an extended protocol is proposed to give different network states information to mobile nodes because there have been no ways for mobile nodes to compare the states of different networks. Sophisticated simulation study is performed in order to evaluate SmartCAC in terms of signaling cost. As a result, signaling cost of ours is up to 96% better than that of the existing scheme.

차세대 이동 네트워크에서는 다양한 무선 접속 기술이 공존하게 된다. 이에 따라, 다양한 무선망에서 QoS를 지원하는 분산 방식의 호 수락 제어 구조인 SmartCAC를 제안한다. 본 논문은 네트워크간 정보 수집이 필요없는 분산방식을 위하여 모바일 노드와 네트워크간의 상호동작을 이용한다. SmartCAC는 기본적으로 VHO 호와 새로운 호1의 구분이 가능하도록 함으로써 VHO 호에 핸드오프를 위해 예약된 채널을 사용할 수 있도록 한다. 또한, 효율적인 호 수락 제어를 위하여 QoS 요구와 네트워크 사용에 대한 delay와 reliability를 다룬다. 뿐만 아니라, 이종망에서 네트워크 필터링을 할 수 있도록 모바일노드의 스피드를 이용한다. 이종망의 상태정보를 알 수 없는 모바일노드가 네트워크의 상태정보를 받아 비교할 수 있도록 확장된 프로토콜을 제시하고, 시뮬레이션 연구에서 기존의 CAC 방식과 제어메시지에 의한 비용을 비교하여 37%에서 96%까지 향상되는 효과를 입증한다.
