Abstract(in English) Recently, as wireless systems diversifies, an integrated wireless network which uses some wireless systems selectively to provide seamless accesses and an effective services to users receives much attention. However, by the spread of multimedia communications via wireless systems leads the spectrum shortage moreover. Although each system uses an individual spectrum prescribed by radio law to avoid radio interference, a number of unused spectrum bands exist on a certain time and/or space in each system. To overcome this problem, dynamic spectrum access technology which can provide an effective spectrum assignment receives much attention. In this paper, we propose a dynamic spectrum assignment method in which a WiFi system temporarily uses a spectrum band of the WiMAX system in WiFi/WiMAX integrated networks to reduce call loss probability of multimedia communication services. The proposed method assigns additional spectrum from WiMAX to WiFi access points based on loss probability prediction.
