摘要: 为支持广泛的QoS级别,需要自动调整5G网络以响应网络状况,以保持最佳的性能效率。5G网络将拥有比前几代蜂窝移动通信网络更多的小区,因此自组织网络(Self-Organizing Network,SON)对于运营商管理复杂的5G网络更为重要。介绍了3GPP工作组SA5和RAN针对5G SON的研究工作,并对自动邻居关系、PCI配置、容量和覆盖率优化、负载平衡优化、移动鲁棒性优化、RACH优化等关键优化技术进行详细阐述。

Abstract: In order to support a wide range of QoS levels, 5G networks need to be automatically adjusted to respond to network conditions in order to maintain the best performance efficiency. 5G networks will have more cells than previous generations of cellular mobile communication networks, so self-organizing networks (SON) are more important for operators to manage complex 5G networks. This article introduces the research work of 3GPP working group SA5 and RAN for 5G SON, and elaborates on key optimization technologies such as automatic neighbor relationship, PCI configuration, capacity and coverage optimization, load balancing optimization, mobile robustness optimization, and RACH optimization.
