Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0013] The present invention obtains a stable fault diagnosis system by analyzing the existing historical fault parameter data set, using SVM (support vector machine) method training, and based on this system, the fault use case of the unknown fault cause obtained is used as the fault use case The input of the system, the system classifies the fault according to the relevant parameters of the fault use case, and the result of the classification is the cause of the fault, so as to achieve the purpose of fault diagnosis. A good classification effect makes the result of fault diagnosis more accurate. Finally, the design of the present invention guarantees the authenticity of the entire mechanism. The specific implementation process is as follows:

[0014] Step 1: KPI value preprocessing

[0015] Step 1.1: KPI vector dispersion normalization. Th...

Abstract

The invention discloses a cellular network fault diagnosis system based on an SVM. The system quickly diagnoses a fault in a network according to the existing network parameter information, and finds the cause of the fault. The system carries out the diagnosis when the network has the fault and the fault is detected. Through the analysis of an existing historical fault parameter data set, the stable fault diagnosis system is trained and obtained through the SVM (Support Vector Machine), and the obtained fault example with the unknown cause is taken as the input of the system based on the above. The system carries out the classification of the fault according to the related parameters of the fault sample, and a classification result is the cause of the fault, so as to achieve the purpose of fault diagnosis.

Description

technical field [0001] The invention discloses a method for quickly diagnosing the occurring fault and finding the cause of the fault according to the existing network parameter information when the network fails under the cellular network. It is used to quickly find the cause of the fault when the cellular network fails, and provide a reference for fault recovery. It belongs to the field of cellular network fault diagnosis. Background technique [0002] In recent years, the surge of applications that require high bandwidth, such as video streaming and multimedia file sharing, will have a huge impact on user behavior in future wireless cellular systems, especially with the emergence of countless smart handheld devices, users The demand for bandwidth is growing at an unprecedented rate. This trend, reflected in user behavior, is putting enormous pressure on the capacity requirements, quality of service, and energy efficiency of cellular systems. In addition, with the appli...
