METHOD AND APPARATUS FOR THE SYNCHRONIZATION OF A SYSTEM TIME OF A COMMUNICATIONS NETWORK WITH A CLOCK REFERENCE

摘要

A system and method for controlling a time synchronization relationship between a communications network (100, 300) time and a module (110) located at a node connected to the communications network for providing a module reference time, the method including determining (410) a time synchronization function is enabled, determining (420) a time difference between the communications network time and the module reference time provided by the module, determining (425) that the determined time difference is greater than a first limit, and less than or equal to a second limit; and gradually adjusting (440), automatically, the network communications network time to synchronize with the module reference time over a predetermined synchronization interval.
