摘　　要：为了使第三代移动通信技术与无线局域网能够最有效地融合,提出了一种新的基于Vague集的多目标决策算法。首先对所提算法的唯一性进行证明,之后针对异构网络中的各个参数值,根据其特点利用不同的公式进行Vague化处理,并利用所提算法对这些处理过的数据进行计算和仿真,最后将仿真结果与传统的模糊集切换算法进行了比较。通过仿真结果的比较可以看出,在异构网络的切换融合中,所提算法更加智能化,同时能更加有效地减少乒乓效应。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.
