Abstract

The embodiment of the invention provides a clock synchronization method and system which are used for solving the technical problem that in the prior art, the stability of clock signals supplied by a clock server is poor. The method comprises the steps that failure detection is conducted on a main clock server of at least two clock servers through a proxy server, wherein the main clock server is the first clock server, for supplying clock information to external equipment, of the clock servers; and if the proxy server determines that the main clock server fails, the proxy server switches the main clock server from the first clock server to the second clock server of the clock servers, and the second clock server supplies the clock information to the external equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a clock synchronization method and system. Background technique [0002] With the development of information technology, communication equipment has higher and higher requirements for clock accuracy. IEEE1588 is a precision clock synchronization protocol standard for network measurement and control systems. Using the precision clock synchronization protocol, the precision can reach the microsecond level. [0003] Generally, in a femtocell network, the femtocell can implement clock synchronization with a clock server through an external global positioning system (Global Positioning System, GPS) clock. However, when using this method to realize clock synchronization, since an external GPS clock needs to be configured for each micro base station, the number of GPS clocks to be used in the configuration process is large and the cost is high. [0004] At present, in a network of mic...
