Abstract

Disclosed are a time synchronization processing method and apparatus. The method comprises: determining a time stability index of a node according to a time deviation value of the node within a preset period of time, where the time deviation value is a delay of a clock signal of the node relative to a reference clock signal within the preset period of time, and the time stability index comprises at least one of the following: a time compensation accumulated value within the preset period of time, a maximum time compensation value within the preset period of time, a time compensation average value within the preset period of time, and a time fluctuation value within the preset period of time; determining whether the time stability index of the node exceeds a preset range; and in a case that the time stability index of the node exceeds the preset range, sending a time synchronization exception alarm. In this manner, by means of the present invention, the problem that time stability of a network or device cannot be detected in the prior art is solved, so as to detect time stability of a network or device in real time according to a time stability index, and ensure time synchronization performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a time synchronization processing method and device. Background technique [0002] With the rapid development of mobile communication network technology including the third generation mobile communication (The Third Generation Mobile Communications, referred to as 3G) technology and the fourth generation mobile communication (The Fourth Generation Mobile Communications, referred to as 4G) technology, the The time synchronization of the mobile backhaul network based on the Packet Transfer Network (PTN) technology puts forward clear and high-precision requirements. [0003] In related technologies, time synchronization is mainly implemented through the 1588v2 protocol, which is also called Precision Time Protocol (Precision Time Protocol, PTP for short). However, to achieve high-precision time synchronization, for example: Time Division-Synchronous Code Division Multiple Access (...
