Abstract

The invention relates to a time synchronization method, a system thereof and time synchronous communication equipment. The embodiment of the time synchronization method comprises the following steps: a clock client end exchanges a time synchronization signal with a clock server to obtain a clock offset between the clock client end and the clock server; the time synchronization signal is transmitted by a special sub-carrier channel of a wire transmission medium; and a clock of the clock client end is adjusted according to the obtained clock offset. The embodiment of the invention lowers the networking cost of a time synchronization proposal applied to the existing base station transmission network adopting the wire transmission medium.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a time synchronization method, system and time synchronization communication equipment. Background technique [0002] Mobile communication systems have very prominent requirements on time synchronization. Time synchronization means that the absolute time between different systems is the same. For example, in a communication system, each system has an internal time, because the internal time of each system operates independently, so the internal time of each system is not necessarily the same. Time synchronization technology is a technology that controls the time deviation between different systems within a specific range. [0003] Different mobile communication systems have different requirements for time synchronization. As shown in Table 1, for GSM (Global System for Mobile Communications), WIMAX (Worldwide Interoperability for Microwave Access), CDMA (Cod...
