Cluster fusion method for warning information in heterogeneous network environment

Abstract

The invention discloses a cluster fusion method for warning information in a heterogeneous network environment. The method comprises the steps of firstly, realizing the unification of frame formats of warnings in a heterogeneous network and the establishment of a warning similarity matrix through a warning preprocessing method; secondly, realizing cluster analysis of similar warnings by utilizing a fuzzy cluster algorithm and dividing the warnings in the heterogeneous network into a plurality of fuzzy warning clusters according to the distances from the warnings to a fault source; and thirdly, fusing warning information in one fuzzy warning cluster by utilizing a Dempster-Shafer theory, and by considering the fusion of warning confidence degrees, finally forming comprehensive warning information, so that the volume of warning data in the heterogeneous network is reduced. The introduced comprehensive warning concept can greatly improve the efficiency of warning processing in an information communication network so as to shorten the warning processing duration of a warning database.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for clustering and merging alarm information in a heterogeneous network environment. Background technique [0002] With the continuous development of communication networks, wireless networks are becoming larger and larger both in terms of capacity and complexity. At the same time, it is becoming more and more difficult to manage various types of information in communication networks. . One of them is the alarm and fault information in the network. As the overall scale of the communication network increases, the possibility of alarm faults in the communication network also increases. Identifying and correcting faults in the communication network in time is the key to ensuring the normal operation of the communication network. At the same time, due to the interaction between the alarm fault and the services provided in the network, it will cause a very large mainten...

Problems solved by technology

From the above development trajectory, it is not difficult to see that there are more and more types of access technologies in modern communication networks, which means that there are more and more different network standards and different standard systems. Under such conditions, the processing of alarm information is more difficult for service providers, because what they need to face is not only a huge amount of alarm data, but also alarm information of various types and formats in different formats, which come from The alarm information of different networks not only has a large amount of data, but also has a variety of types, which is a bigger challenge and topic for service operators
