摘　　要：在数据分流传输时,考虑应用数据业务的多样性,根据要传输业务的特点进行业务流分配。分析异构无线网络中单个用户并行多网络传输的业务分流特点,提出一种面向多业务的分流策略。引入经济学概念建立基于效用函数的分流策略,结合不同类型业务,考虑消耗和收益2个因素,构造效用函数,求解最优化问题,并证明所分配的结果是全局化最优解。仿真结果表明,与负载均衡算法相比,该分流策略能有效降低时延和成本。When the data is diverted,considering the diversity of the application data business,allocating the traffic flow according to the characteristics of the transmission business,and analyzing the characteristics of the traffic diversion of single user parallel multi network transmission in the heterogeneous wireless network,a multi-business shunt strategy is proposed.It introduces the concept of economics to establish triage strategy based on utility function,and combines the different types service to consider two factors of consumption and income.Then it constructs the utility function for solving optimization problems,and proves the result which is the global optimal solution.Simulation results show that the proposed strategy can reduce delay and cost effectively compared with the load balancing algorithm.
