Efficient support for multimedia communication is essential for next generation mobile wireless networks. In order to provide the necessary quality of service (QoS) on demand in mobile wireless networks, appropriate signaling has to be defined. We present a mobility-aware QoS signaling architecture that integrates resource management with mobility management. It is based on a domain resource manager concept and nicely supports various different handover types. In particular, our approach supports anticipated handover with pre-reservation of resources before the mobile node is attached to the new access point. In this paper, we discuss the signaling protocol of our architecture with focus on the different handover cases, for which QoS signaling is described in an integrated handover model.
