为解决LTE网络中蜂窝中断带来的覆盖和质量问题,提出了一种分布式自组织网络管理体系结构和分布式蜂窝中断补偿管理机制。在对小区停电进行检测和分析后,提出了一种基于参考信号功率调整的小区停电补偿算法。仿真结果表明,所提出的机制可以显著缓解性能下降。与其他算法相比,该方案能更好地补偿因小区中断引起的覆盖缺口。
To solve the coverage and quality problems caused by cell outage in LTE networks, this paper proposes a distributed self-organizing networks management architecture and a distributed cell outage compensation management mechanism. After detecting and analyzing the outage, a cell outage compensation algorithm based on reference signal power adjustment is proposed. The simulation results show that the proposed mechanism can mitigate the performance degradation significantly. Compared with other algorithms, the proposed scheme is more effective in compensating the coverage gap induced by cell outage.
