摘　　要：针对异构无线通信网络的发展趋势及其负载控制的执行,利用复杂系统中端到端重配置管理能力,结合模糊理论中的决策算法,提出了一种基于模糊理论的增强型多目标决策层次分析法(AHP)终端选择算法——AHP-TS,该算法将可重配置系统中的差异性和不精确性模糊化为相应隶属函数的隶属度,以实现更加及时有效的负载调控,进一步提升系统性能。理论分析和仿真所得出的结果均显示,在平衡可重配置系统中具有重叠覆盖的异构无线通信网络间的业务负荷中,此算法可以更好地实现不同负载条件下系统性能与管理开销间的折中,提高用户满意度。In view of the development trend of heterogeneous wireless communication networks and their execution of toad control, the paper proposes the AI-IP-ST, an enhanced tenrtinal selection （TS） algorithm based on the analytic hierarchy process （AHP） and the fuzzy theory by exploiting the ability of end-to-end reconfiguration management. It can be regarded as a novel terminal selection algorithm to decide the most appropriate target terminals for more timely and effective load re-allocation so as to improve the system performance further. The results of the theoretical analysis and simulation demonstrate that the proposed algorithm is adjusted dynamically and adaptively to achieve better trade-off between system performance and controlling overhead, and improve users＇ satisfaction under the overlapped heterogeneous radio access technologies within an end-to-end reconfiguration system.
