关于异构无线网络中的呼叫接纳控制和负载均衡策略的研究很多，大多数研究都是基于UMTS和WLAN之间的唯一区别是覆盖和带宽，提出了一种新的基于效用的呼叫接纳控制和负载均衡策略，该策略充分利用了网络的跨层特性和负载均衡特性，并在此基础上提出了一种新的基于效用的呼叫接纳控制和负载均衡策略。仿真结果表明，该策略能够最大化异构无线网络中所有正在进行的连接的总效用。
There are many researches on call admission control and load balancing strategy in heterogeneous wireless networks,most of which are under the consideration that the only difference between UMTS and WLAN is the coverage and bandwidth,yet the network characteristics at physical layer and link layer are not taken into account.A novel utility-based call admission control and load balancing strategy is proposed.The proposed strategy utilizes the cross-layer information of both the characteristics at lower layer,and utility functions defined at the application layer.The simulation results show that the proposed strategy maximizes total utility of all the ongoing connections in heterogeneous wireless networks.
