Abstract
A method and device for implementing a compensation for an asymmetry delay of a 1588 link are provided. The method comprises: measuring and calculating a value of an asymmetry delay of the 1588 uplink/downlink; performing an asymmetry delay compensation when the value of the asymmetry delay exceeds a set synchronization offset range; and continuing a normal 1588 time synchronization if the value of the asymmetry delay does not exceed the set synchronization offset range; and implementing the automatic compensation for the asymmetry delay of the 1588 link. The above-mentioned scheme can correct the asymmetry delay automatically, and ensure the quality of 1588 time synchronization.
