摘　　要：为有效降低异构无线网络拥塞,提高网络收益,提出了网络收益最大化的呼叫接纳控制(Call Admission Control,CAC)算法。首先模拟异构无线网络场景,考虑网络带宽及时延参数,定义网络收益函数,其次解决网络收益最优化问题。仿真结果显示,该算法可以高效地降低网络拥塞,均衡负载并提高网络收益。To effectively reduce the congestion of heterogeneous wireless networks and increase the network rev-enue, a call admission control algorithm based on maximum network revenue is proposed. Firstly, simulation scen-ario for heterogeneous wireless network is proposed, a new reward function is defined with consideration of the network bandwidth and delay parameters. Then, the network revenue optimization problem is solved. Results of the simulation indicated the proposed CAC scheme efficiently relieved the congestion, balanced the load and im-proved the network reward.
