Research on 5G Time Synchronization Optimization Scheme in IPRAN
It proposes a series of solutions to the high cost and low security issues of using GPS synchronization for 5G base stations.Firstly,it uses dual-mode modules to solve the security issues of satellite timing.Then,it adopts active power distribution and passive power distribution solutions to solve the problem of limited installation of satellite antennas and reduces construction costs.When satellite antennas cannot be installed,1588v2 technology is used to deploy master slave clock sources within the IPRAN ring.The scheme can achieve synchronization accuracy of 100 ns and significantly reduce the deployment cost of 5G time synchronization.It has a certain reference value for the optimization and deployment of 5G time synchronization technol-ogy.
