Summary:
The stable operation of 5G services is closely related to the quality of synchronized signals, which will directly affect the quality of 5G services. This study provides the establishment of a network management system to monitor the status of the synchronous clock source of each single end-to-end circuit in the 5G network, and to detect the deterioration or abnormality of the synchronous clock source in advance. The process proposed by this system includes the following functions, clock source analysis of information network equipment synchronization obstacle, and clock source switching method of synchronization obstacle. The clock source analysis of synchronization obstacles is determined by regularly analyzing the two synchronization signal sources of the network equipment, the time difference (TD) between the GPS receiver and the back end PTP clock source, and the synchronization obstacle events and synchronization offsets of the base stations under its control. Whether the clock source service is working properly. The clock source switching method for synchronization obstacles, analyzes the synchronization quality of the base station under the NAR equipment, obtains the synchronization parameters measured by the base station, and obtains the back end PTP synchronization time increase and decrease for cross-comparison. In the case of not affecting the network service, the clock source of the network equipment is pointed to a better source to provide services. Through this mechanism, it can proactively test whether there is any abnormality in the equipment, locate the obstacle equipment, and shorten the repair time.
