| Abstract: | With the development of heterogeneity of wireless networks,providing users with the best connection anytime and anywhere is the key function of future wireless networks.To maximize userg quality of experience,an access selection algorithm based on network states and user preferences is proposed.In this algorithm,decision-making factors are decided by users and a unified multi-attribute normalized method is designed to meet dynamic adaptability.In addition,an analytic hierarchy process method is adopted to calculate the subjective weight of multi-attributes.Simulation results show that the proposed algorithm can improve user＇ s satisfaction as well as decrease system blocking probabilies and balance the load of networks. |

| Keywords: | quality of experience （QoE） network load analytic hierarchy process network selection |
