Abstract

The invention provides a time synchronization signal transmission method, device and system, relates to the technical field of communication, and can realize time synchronization signal bearing and transmission through an IPRAN + OTN network. The transmission method can be applied to an optical transport network (OTN) device, the OTN device is connected with a time server, and the OTN device is connected with an internet protocol radio access network (IPRAN) device. The transmission method comprises the following steps: receiving a time synchronization signal sent by a time server, wherein the time synchronization signal comprises a time signal and a frequency signal; and sending a time synchronization signal to the IPRAN equipment.

Description

technical field [0001] Embodiments of the present application relate to the field of communication technologies, and in particular, to a method, device, and system for transmitting a time synchronization signal. Background technique [0002] In a wireless network technology, a base station needs to obtain a time synchronization signal generated by a time server, and then update its own time according to the time synchronization signal. In the fifth generation wireless systems (5G), 5G base stations have higher requirements for the accuracy of time synchronization, and need to update their own time based on the time signal and frequency signal generated by the high-precision time server. [0003] Specifically, the high-precision time server can transmit the time signal and the frequency signal to the base station through a radio bearer. However, in the prior art, there is no method for carrying and transmitting a time synchronization signal through an Internet protocol radio...
