Abstract

A method for synchronizing clocks in a communication network includes a first clock of a first network element which is a master element is used for synchronizing second clocks of one or more second network dements which are slave elements. A first sequence of first messages transmitted from the first network element to the second network element and/or a second sequence of second messages transmitted from the second network element to the first network element is recorded. First messages and/or second messages out of those sequences are identified by using an appropriate threshold function with respect to the transmission delays of those messages. Those identified messages have the same constant minimum delay, and based on those messages clock synchronization between the first clock and the second clock is performed.
