摘要
作为必不可少的基础支撑网络,5G同步网急需在技术和产业发展方面尽快推动。面向5G系统高精度时间同步需求,提出高精度同步通用组网模型,重点研究高精度源头、高精度同步传输、高精度同步监测等若干高精度同步关键技术。
As an indispensable basic support network,5G synchronization network urgently needs to be promoted in technology and industrial development as soon as possible.Based on the analysis of the time synchronization requirement of 5G system,the necessity of solving 5G system synchronization based on high precision time synchronization ground network is analyzed,and a general network model of high precision synchronization is proposed.The key technologies such as high precision source,high precision synchronization transmission and high precision synchronization monitoring are mainly studied.
