Abstract
B3G 네트워크에서 서비스 제공자와 사용자 사이에 SLA (Service Level Agreement)가 정해지면 서비스 제공자는 정해진 QoS 맞게 서비스를 제공하여야 한다. 하지만 네트워크는 상황은 시간에 따라 변하며, 서비스 제공 환경이 변할 수 있다. 따라서 네트워크 서비스에 대해서 동적인 QoS 관리 방안이 고려되어야 한다. 본 논문에서는 B3G 융합망에서 네트워크 상황에 따라 동적인 QoS를 위한 핸드오버 방안에 대해 제안한다. B3G 네트워크에서 동적인 QoS 관리를 위하여 이종의 망을 이용하게 된다. The SLA (Service Level Agreement) is once determined between service provider and users in B3G networks so that the network service must be provided as QoS management. Here, the network situation is changed as the time flow, and the service environment is also altered. Hence, dynamic QoS management scheme should be considered. In this paper, we propose a handover scheme for dyanamic QoS as the network situation in B3G networks. The heterogeneous networks can be used for dynamic QoS management in B3G networks.
