Abstract

The invention discloses an LTE uplink interference classification method based on PCA and a two-dimension skewness feature. The method comprises the following steps: firstly collecting and sorting outuplink interference classification data of the existing LTE base station; and then performing PAC dimension-reduction and extracting the two-dimension skewness feature after preprocessing the data; setting a model parameter search range to obtain an optimized classification model; and finally judging whether the interference is existent by performing average interference level statistics on an unknown cell, extracting this method feature to place in the trained model to perform the prediction classification if the interference is existent. Through the method disclosed by the invention, the evaluation is performed by using an AUC classification performance index; the uplink classification category can be accurately and fast judged through the classification method, and the classifier performance can be continuously improved with the increase of the uplink interference data size.

Description

technical field [0001] The present invention relates to a method for classifying LTE uplink interference, in particular to a method for classifying LTE uplink interference based on PCA and two-dimensional skewness features. Background technique [0002] The LTE uplink interference level is an important indicator for evaluating network quality. When the network suffers from uplink interference, the uplink throughput, especially the uplink throughput of cell edge users, will be affected. When the interference is severe, it will even affect the user's access performance. In today's network test solutions, the artificial uplink interference classification and troubleshooting method can analyze the interference situation in the established cells. However, as the scale of the base station network becomes larger and larger, the degree of network interference will become more serious. In the future, there will be tens of thousands of base stations. At the scale of the deployment, th...
