Title:
METHOD AND DEVICE FOR CLOCK LINK SWITCHING AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2017/101528
Kind Code:
A1
Abstract:
Disclosed are a method and device for clock link switching and a base station. The method comprises: receiving first synchronization information transmitted by a primary clock server and second synchronization information transmitted by a backup clock server; calculating, on the basis of the first synchronization information and the second synchronization information, the difference in jitter values of a primary clock link and of a backup clock link and a packet loss rate of the backup clock link; and, when the difference in the jitter values remains in a preset range for a preset time and the packet loss rate of the backup clock link is less than a first preset value, making the backup clock link as a new primary clock link. Embodiments of the present invention, by comparing and analyzing clock performances of both the primary clock link and the backup clock link, and selecting in a timely manner the clock server of better clock performance to switch to as a clock source, implement rapid and accurate switching of clock links, save time in link switching, and increase link synchronization performance to a certain extent.
