摘要：Next generation networks are defined to be packet based networks that provide telecommunication services to users by utilizing different transport technologies, wired and wireless. In this paper we provide a generic framework for handover decision management in next generation networks. We show that any handover decision algorithm can utilize our framework. We show the feasibility of applying our framework through an implementation example. One of the main features of NGNs is application adaptability; the applications designed for NGN systems have to be adaptable to different networks and different devices. We propose a handover decision algorithm that utilizes our generic framework and selects the network for handover such that the quality of experience of the user is near optimal. Through simulations we show that our algorithm reduces unnecessary handovers and also satisfies the handover requirements.
