阅读说明：本技术 时钟同步的方法和装置 (Method and device for clock synchronization ) 是由 傅健新 于 2019-02-15 设计创作，主要内容包括：一种时钟同步的方法和装置,该方法包括：控制第一网元的第一计时器与第二网元的第二计时器处于时间对齐的状态,该时间对齐的状态为在相同时间内该第一计时器和该第二计时器的时间增量相同(S101)；在该时间对齐的状态下,根据目标时钟对应的相邻的两个上升沿的出现时间或相邻的两个下降沿的出现时间,获取该目标时钟的周期信息或频率信息,该目标时钟的周期信息或频率信息用于该第二网元获取与该目标时钟同步的时钟,该目标时钟为需要从该第一网元传输至该第二网元的任一时钟(S103)；将该目标时钟的周期信息或频率信息发送至该第二网元(S104)。上述时钟同步网元间的时钟同步占用的物理资源少,简单易实现。(A method and apparatus for clock synchronization, the method comprising: controlling a first timer of a first network element and a second timer of a second network element to be in a time alignment state, wherein the time alignment state is that time increments of the first timer and the second timer are the same within the same time (S101); in the time alignment state, acquiring cycle information or frequency information of a target clock according to the occurrence time of two adjacent rising edges or the occurrence time of two adjacent falling edges corresponding to the target clock, where the cycle information or frequency information of the target clock is used by the second network element to acquire a clock synchronized with the target clock, and the target clock is any clock that needs to be transmitted from the first network element to the second network element (S103); and sending the period information or the frequency information of the target clock to the second network element (S104). The clock synchronization between the clock synchronization network elements occupies less physical resources, and is simple and easy to implement.)
