Abstract

In this paper, we propose a scheme for the support of flow mobility according to a QoS condition when a mobile node with multiple wireless interface moves and attaches to a different access network. For this purpose, we extend the fields of the PBU/PBA message and add an additional request procedures. Through the proposed scheme, we can provide the best service in according to the network conditions of the next access network based on the measured QoS values by LMA. Finally we consider the state transition diagram of our proposed scheme and confirm its operation.

본 논문은 무선 네트워크에서 하나의 단말기가 복수의 인터페이스를 이용하여 상이한 액세스 네트워크에 접속할 때 QoS에 따른 플로우 이동성 지원을 위한 방안을 제안한다. 이를 위해서 PBU/PBA 메시지의 확장 및 LMA에 추가적인 QoS request 메시지 절차 추가하였다. 제안한 방법을 통해 LMA가 이동할 네트워크에 대한 QoS정보를 수집하고 플로우 이동을 결정하여 사용자에게 네트워크 상황에 따른 최적의 서비스를 제공할 수 있다. 제안한 방안은 state transition diagram을 이용하여 수행 여부를 확인하였다.
