<p>A network clock synchronization apparatus (32) relating to the communication technology field includes a filter selector (321), a synthesis and adjustment algorithm module (322), a frequency regulator (325), an oscillator (326) and a time synthesizer (323), in which the filter selector (321) receives the reference source time information of a time server (31) and thereby generates the standard time information; the synthesis and adjustment algorithm module (322) obtains a frequency difference by comparing the standard time information output from the filter selector (321) with the local time information output from the time synthesizer (323); the frequency regulator (325) regulates its output local clock signal according to the frequency difference provided by the synthesis and adjustment algorithm module (322), in which the local clock signal source comes from the oscillation source clock signal provided by the oscillator (326); the time synthesizer (323) synthesizes the local time information from the local clock signal coming from the frequency regulator (325). A system and method can meet the requirement of the clock synchronization of the service device at the lower cost.</p> |
