Embodiment Construction

[0055] Embodiments of the present invention provide a method and device for determining the working state of network equipment, which are used to solve the technical problem of how to determine the time period for a base station to maintain a stable working state after GPS loses lock.

[0056] In order to solve the above technical problems, the general idea of ​​the embodiments of the present invention is as follows:

[0057] A method for determining a working state of a network device, the method comprising:

[0058] Record at least one parameter value of the system clock of the network device within a preset period of time before the current time; wherein, the current time is the time when the network device enters the GPS out-of-lock state, and each of the at least one parameter value Each parameter value is the phase difference between the clock signal generated by the system clock and the reference signal at the preset sampling time, and / or each parameter value is the clo...

Abstract

The invention discloses a network equipment working state determination method and device. The method comprises the steps that at least one parameter value, in a preset time period before a current moment, of a system clock of network equipment is recorded, wherein the current moment is the moment when the network equipment enters a GPS lock-losing state; on the basis of the at least one parametervalue, the working stability of the system clock at the current moment is estimated; and according to a preset mapping relation, the time that the network equipment is in a normal working state afterthe current moment is estimated, wherein the preset mapping relation is the relation between the working stability and the time that the system clock can keep the normal working state after being inthe GPS lock-losing state.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for determining the working state of network equipment. Background technique [0002] The base station may lose lock of the Global Positioning System (GPS) due to various complicated situations in the field. When the GPS is out of lock, the base station will enter a holdover state, that is, the system clock of the base station cannot be continuously calibrated by using the GPS as a reference clock. The base station cannot keep running without a reference clock for a long time, but it can maintain a normal working state for a period of time, so maintenance personnel can maintain the base station within this period of time. [0003] Usually, the loss of GPS signal in a certain area affects more than a single base station. When there are multiple base stations at the same time and the GPS loses lock at the same time, maintenance personnel ...
