The third generation mobile communication technology and wireless LAN are required to integrate effectively. In or-der to have the most effective integration, this paper proposes a new multi-objective decision algorithm based on Vague set.Firstly, this paper proves the uniqueness of the proposed algorithm. Then, according to each parameter value in heterogeneousnetwork and its characteristic, we use different formulas to deal with parameters, and use the proposed algorithm to calculateand simulate data. Finally, the simulation results are compared with those of the traditional fuzzy switching algorithms. Bycomparing the simulation results, we find that the proposed algorithm is more intelligent, and can effectively reduce the ping-pong effect in a heterogeneous network switch in the integration.
