Problems solved by technology

In this scenario, if the key parameters such as time source accuracy, stability, and phase provided by each ATOM GPS are equivalent (for example, they all come from GPS satellite signals), then there will be no actual benefits for time source switching, but there will be related events and alarm reporting, which increases unnecessary explanation and maintenance costs, and the process of source switching may also be accompanied by time jumps and degradation of performance

Abstract

The invention discloses a method for detecting a time source, and network equipment. The method comprises the steps that first network equipment employing a first time source obtains the information of a second time source employed by second network equipment; the first network equipment forbids the switching of the time source of the first network equipment to the second time source from the first time source. Therefore, through the comparison of the current time source of the network equipment with the time source obtained by other network equipment, the method can carry out no switching ofthe time source when the information of the two time sources is the same, and avoids the additional expenditure caused by the unnecessary switching of the time source.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and network equipment for determining a time source in the communication field. Background technique [0002] In a communication network, the normal operation of many services requires network clock synchronization, that is, the time or frequency error between devices in the entire network is kept within a reasonable error level. With the development of communication technology, the current network has higher and higher requirements for time synchronization (for example, base stations in 3G / 4G / 5G communication networks), and the commercial deployment of time synchronization functions is very extensive. [0003] Generally, at least two time source devices are deployed in the live network, one as the primary time source device and the other as the backup time source device. In this scenario, if the primary time source device is such as the ATOM Global Positioning System (ATOM Glo...
