Problems solved by technology

[0002] The base station equipment needs to be synchronized in the air. In the case of multi-base station source boards sharing the chassis, frame header synchronization between base stations is required. The current method is mostly GPS distribution, or each synchronizes separately, but the existing synchronization methods are costly. Synchronization low success rate

Abstract

The invention provides a method and a system for synchronization of multiple synchronization sources, and in the system for synchronization of multiple synchronization sources, each single informationsource plate is connected through a ring mode; the information source plate comprises a baseband processing module and a timed generation and distribution module, wherein the timed generation and distribution module comprises a second pulse selection module, a K1 switch, a second pulse generation module and a K2 switch; the second pulse selection module is connected with the K1 switch; one end ofthe K1 switch is connected with the baseband processing module while the other end thereof is connected with a 1pps signal port; and the second pulse generation module receives 40ms or 80ms signals of output of the baseband processing module, generates a 1pps signal and outputs the generated 1pps signal to the k2 switch. Through the method and the system for synchronization of multiple synchronization sources provided by the invention, GPS, 1588 and air synchronization can be achieved, simultaneously, a function of synchronous distribution of various information source plates is supported, and effects of reducing hardware cost and improving synchronization success rate are realized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for synchronizing multiple synchronization sources. Background technique [0002] The base station equipment needs to be synchronized in the air. In the case of multi-base station source boards sharing the chassis, frame header synchronization between base stations is required. The current method is mostly GPS distribution, or each synchronizes separately, but the existing synchronization methods are costly. Synchronization low success rate. Contents of the invention [0003] In view of the above problems, the present invention proposes a method and system for synchronizing multiple synchronization sources to achieve synchronization of different synchronization sources, and simultaneously support the synchronous distribution function of different source boards. As long as one source board is synchronized, other signal boards can be synchronized. The sour...
