Embodiment 1

[0052] The method for training the first fault detector will be introduced below through an embodiment.

[0053] For most centralized access networks, the network architecture can be abstracted into multiple layers. Since each layer has different characteristics, according to an embodiment of the present invention, each layer in the network architecture of the centralized access network can be The first fault detectors are respectively trained to detect abnormal events by using the first fault detector corresponding to the layer when performing abnormal detection.

[0054] For the above embodiment, when training the first fault detector, the corresponding operating data of the layer can be selected in combination with the characteristics of each layer to be used as the training sample of the negative selection algorithm, and the same category as the training sample can be selected when implementing step 1 Anomaly detection of the data to be tested.

[0055] refer to figure 1...

Embodiment 2

[0106] According to Embodiment 2 of the present invention, a method for performing anomaly detection on a centralized access network is provided, refer to figure 2 , the method includes:

[0107] Step 1. For the centralized access network, a first fault detector is used to detect abnormal events, wherein the first fault detector is trained based on the operation data of the centralized access network itself and using a negative selection algorithm.

[0108] According to an embodiment of the present invention, the first fault detector is obtained through training using the method in Embodiment 1.

[0109] The inventors have found that the failure characteristics of the above layers conform to the following rules, that is, if the current layer fails, there is a high probability that the lower layer will also be abnormal. For example, if the indicators at the network layer are abnormal, there will usually be abnormalities at the lower network element layer. Therefore, directly...

Abstract

A method for executing anomaly detection on a centralized access network comprises the steps that (1) for one layer in a network architecture of the centralized access network, a first fault detectorcorresponding to the layer is adopted for abnormal event detection, and the first fault detector is obtained through training by adopting a negative selection algorithm based on operation data of thelayer; (2) when the first fault detector detects that one component has multiple pieces of fault information, the first fault detector detects that the component has multiple pieces of fault information; a second fault detector is employed to perform an intersection operation on a plurality of pieces of fault information of the component to determine a fault of the component, wherein one of the pieces of fault information is represented as a set of abnormal events occurring on the component and all abnormal events associated with the abnormal event.

Description

technical field [0001] The invention relates to fault detection of a wireless communication system, in particular to fault detection for a centralized access network. Background technique [0002] Centralized access network (C-RAN) is a new type of resource management and control system, which creates a large number of virtual base stations on demand in a large-scale centralized resource pool through a unified and open interface, so as to realize sharing between multiple virtual base stations resource. However, for such a shared resource pool, once there is a problem with the resources in the resource pool, it may cause failures of multiple base stations associated with it, which will affect the services of access users in a wide range, and even cause the entire network to fail. collapse. Therefore, it is necessary to set up a fault management system for the centralized access network. [0003] Fault detection is the first step of fault management, and its detection effec...
