Today, packet services for wireless internet is provided by WiBro WLAN 3G, but it is hard to be satisfied seamless connection in each of networks and wide-area service will increase the number of BS(base station) because WiBro and WLAN has been coverage smaller than 3G. that is, communicate which can use continuous and seamless data service is available when user is moving. Therefore, service provider need to integrate network for reducing management expenses. In this paper, we propose advanced handoff algorithm which is considered by 'user demand bandwidth', 'MN(Mobile Node) movement speed' and 'MN service area' and show that simulating result is superior to 'bandwidth allocation', 'QoS(Quality of Service) rate' and 'handoff failure rate'
