Fault locating method and device in communication network

Abstract

The invention discloses a fault locating method and device in a communication network, and the fault locating method and device are used for solving the problem existing in the prior art that the fault locating accuracy is low. The fault locating method comprises generating at least one first alarm frequent item set; obtaining a candidate parent alarm polling list; wherein the candidate parent alarm polling list comprises several candidate parent alarms, candidate parent alarm mutex relationship identifications and candidate parent alarm priority; determining an alarm which is the same as one candidate parent alarm in the candidate parent alarm polling list in the at least one first alarm frequent item set as a candidate parent alarm; determining a second alarm frequent item set which does not include candidate parent alarms having a mutex relationship in each first alarm frequent item set including candidate parent alarms in dependence on the candidate parent alarm polling list; and selecting one candidate parent alarm as the parent alarm in dependence on the corresponding priority of each candidate parent alarm in each second alarm frequent item set in the candidate parent alarm polling list; and determining the fault point in dependence on the parent alarm.

Description

technical field [0001] The invention relates to the technical field of network monitoring, in particular to a fault location method and device in a communication network. Background technique [0002] The communication network is composed of various types of network element equipment, and different network elements cooperate with each other to complete the communication function; each network element contains different components, and cooperates to realize the main functions of the network element. This kind of interdependence between network element components and network elements makes when a certain network element or component fails and alarms, it will trigger a series of corresponding alarms of different types, forming an alarm storm. For example, if network element x fails, two alarms may be sent, one for connection failure and one for data packet loss; before the fault is resolved, network element x will send a message every time it tries to send information and fails...
