METHOD AND SYSTEM FOR CLOCK SYNCHRONIZATION OF NETWORK TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a method and system for the clock synchronization of network terminals.

SOLUTION: The method and system for network terminal clock synchronization includes: determining each round trip delay time from a master terminal to each slave terminal; and offsetting the clock of each slave terminal by an amount proportional to each determined round trip delay time such that the master terminal and each of the slave terminals have about the same point of reference in time. The method and system further includes, in response to a trigger signal; determining an individual offset between the master clock of the master terminal and each of the clocks of the slave terminals; and offsetting each of the clocks of the slave terminals by an amount proportional to each determined offset to synchronize each of the slave terminals to the master clock of the master terminal.
