Method and device for locating communication network faults

Abstract

The invention discloses a fault positioning method and device of communication network. The method mainly comprises that communication signaling among network elements is monitored, call records are generated and the percent of completed voice calls is calculated according to the monitored communication signaling, and the call records comprise the network elements, which the voice call passes successively, at least; if the percent of completed voice call is lower than a set threshold, according to failure reasons of the call records in which voice connection fails, the proportions of failure calls caused by the different reasons are determined, the failure reason of the highest frequency is selected from the failure reasons, whose proportions of failure calls are greater than the proportion of failure calls in normal voice connection, as the first failure reason, and all calling records in connection failure caused by the first reason are selected from the calling records in voice connection failure to form fault positioning decision sets; and intersection sets are selected from the fault positioning decision set, and the last network element of the intersection sets is determined to be the fault network element. The method can be used to position the fault network element rapidly.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method and device for fault location of a communication network. Background technique [0002] With the growth of mobile users and the increase of business types, the number of communication network elements is also increasing, and the failure of communication network elements is also more frequent. After the occurrence of communication failures, analysis and location of failures are usually in the entire fault handling process. Taking up the most time, how to quickly locate faulty network elements, fault time, fault range, faulty services, and fault causes has become a key problem that the operation and maintenance department needs to solve, especially in the centralized operation and maintenance management mode, facing the needs of large-scale network elements more urgent. [0003] At present, the fault location is generally realized through the mass...

Problems solved by technology

[0005] The embodiment of the present invention provides a communication network fault location method, which is used to solve the problem in the prior art that the fault location network element only performs fault analysis on the faulty network element that generates an alarm, and the fault location accuracy is low and takes a long time.
