The present invention provides a SON coordination method, device, and system, and the method includes: obtaining a coordination parameter of a self organizing network function; and coordinating running of the self organizing network function according to the coordination parameter. The coordination parameter of the SON function is obtained before running of a current SON function, so as to use the obtained coordination parameter to coordinate the running of the SON function. In this way, the running of the current SON function may cooperate and coordinate with another SON, thereby avoiding a conflict, more efficiently, more smoothly, and lower repeatedly solving a network problem, improving network application efficiency, or reducing wrong adjustment of a network parameter caused by wrong judgment, which affects user service experience, so as to achieve an object of reducing an operating cost, and improving an utilization rate of an equipment and funds.
