摘要
异构网(Het Net)的引入及多制式网络的共存,使4G LTE网络运维复杂程度大为增加。2007年3GPP在进行LTE标准制订时,引入了LTE自组织网络(SON)机制,旨在移动网络建设和优化时能自动完成网络设备的参数配置,提升网络建设与维护效率,降低网络运营成本。经过多年的演进发展,SON功能已日渐丰富和完善。介绍了SON技术及其体系架构,举例说明了SON技术在我国的应用情况及效果,提出了SON技术发展面临的挑战。
The introduction of heterogeneous network（Het Net） and the coexistence of multi-system networks make 4G LTE network operation complexity increase greatly.In 2007 3GPP LTE standard setting,the LTE self-organizing network（SON） mechanism is introduced,to complete the automatic parameter configuration of mobile network devices,enhance the network construction and maintenance efficiency and reduce OPEX.After many years of development,the SON function becomes increasingly rich and perfect.This paper introduces the SON technology and its functional architecture,illustrates the application and effect of SON technology in China,and puts forward the challenges of SON technology development.
