Abstract: Wireless mobile multimedia communications have been greatly increased in the number ofusers, diversity of applications and interface technologies. Wireless mobile networks are beingevolved and integrated into IP based core network, so it is necessary to provide sufficient QoS(Quality of Service) mechanism to provide enhanced user’s satisfaction. In this paper, wepropose a new adaptive QoS mechanism based on utility function borrowed from the field ofmicroeconomics, call setup and handover signaling mechanism integrating QoS and mobilitymanagement. Through a simulation, we show that adaptive resource allocation based on userpreferences can be realized in the wireless mobile n
