In this paper

a QoS (quality of service) handover decision scheme with ABC (always best connected) supported is proposed.With knowledge of fuzzy mathematics and microeconomics introduced

application types

QoS requirements

access networks and terminals are described.With application QoS requirements

costs user willing to pay

user preferences to access network coding schemes

user preferences to access network providers

terminal velocities

terminal battery capacities and access network conditions considered comprehensively

an optimal handover solution of assigning N terminals to M access networks is found based on niche PSO (Particle Swarm Optimization) algorithm.With the help of gaming analysis

Pareto optimum under Nash equilibrium of user utility and network provider utility is achieved or approached for the found solution.Simulation results showed that the proposed scheme was effective.
