Abstract: In this paper, a handover decision scheme with ABC supported was proposed. Comprehensively considering access network conditions, application requirements, user preferences to access network coding schemes, user preferences to access network providers, terminal velocities and terminal battery capacities, an optimal handover solution was found based on PMA (Population Migration Algorithm). With the help of gaming analysis,Pareto optimum under Nash equilibrium of user utility and network provider utility was achieved or approached for the found solution. Simulation resups showed that the proposed scheme was effective.
