能源效率和自组织网络结构是未来蜂窝系统的首要问题。本文提出了一种适用于长期演进(LTE)蜂窝系统的节能自组织接入网络体系结构。通过在LTE演进UMTS地面接入网络(E-UTRAN)中经由X2接口通信的演进节点B(ENB)之间的智能协作来实现自组织特性。通过使用所提出的协调和协作，E-UTRAN利用最少数量的活动eNB并将冗余eNB切换到休眠模式来实时地动态地重新配置。评估了不同网络场景、小区布局和基站功率消耗情况下的系统性能。仿真结果表明，网络的能量消耗大幅下降。此外，网络在利用其可用容量方面变得更加高效。
Energy efficiency and self-organizing network architectures are the top issues for future cellular systems. In this paper, we propose an energy saving self-organizing access network architecture for long term evolution (LTE) cellular systems. Self-organizing nature is attained through intelligent cooperation among the evolved node Bs (eNBs) communicating via X2 interface in the LTE evolved UMTS terrestrial access network (E-UTRAN). Using the proposed coordination and cooperation, the E-UTRAN is dynamically reconfigured in real-time utilizing minimum number of active eNBs and switching the redundant eNBs into sleep mode. System performance under different network scenarios, cell layouts and eNB power consumption profiles is evaluated. Simulation results indicate a substantial drop in the network's energy consumption. In addition, the network becomes more efficient in utilization of its available capacity.
