A method and device for detecting uplink external interference

Abstract

The invention discloses an uplink external interference detection method and apparatus. The method comprises the following steps: acquiring a telephone traffic statistical data; according to proportions of an interference band 4 and an interference band 5 and a telephone traffic amount, screening suspected interference cells; obtaining information of the suspected interference cells, wherein the information comprises base station position information, azimuth information and neighborhood relations of the suspected interference cells; according to the information, determining position logic hierarchical relations between the suspected interference cells and surrounding cells; and through interference conditions of the surrounding cells of the suspected interference cells, determining suspected interference cells causing uplink external interference.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an uplink external interference detection method and device. Background technique [0002] The rapid growth of mobile communication users has brought about the rapid expansion of the scale of mobile communication networks. With the continuous expansion of the network scale, the level of network interference will increase to varying degrees. [0003] Interference has always been one of the main factors affecting network quality. Interference will lead to call failure, poor quality noise, call drop, etc., seriously affecting customer perception, and is a very critical issue that leads to network quality degradation. Interference is divided into uplink interference and downlink interference. Downlink interference is mainly frequency interference within the network, while there are many types of uplink interference, mainly interference caused by hidden equipment failures, in...

Problems solved by technology

[0003] Interference has always been one of the main factors affecting network quality. Interference will lead to call failure, poor quality noise, call drop, etc., seriously affecting customer perception, and is a very critical issue that leads to network quality degradation

However, during network measurement, it is inevitable to encounter various problems, such as insufficient sampling points, failure of the base station itself, and problems caused by other accidental factors. These problems directly affect the comprehensiveness and accuracy of the measurement data, making the measurement data difficult to be true Accurately reflect the network situation

At the same time, not all equipment manufacturers support the uplink frequency scanning measurement function. For manufacturers without the uplink frequency scanning measurement function, the methods for analyzing external uplink interference are very limited, relying more on the experience of technicians and on-site frequency scanner data, and the efficiency of positioning and troubleshooting is low.
