5G fronthaul network quality detection method

Abstract

The invention discloses a 5G fronthaul network quality detection method, and the method comprises the following steps: S1, completing the test of an in-use wave channel in a 5G fronthaul network by adopting an optical power detection instrument and an out-of-band wavelength OTDR whole-course test method, in the testing process, employing a detection instrument for detecting the light emitting power of a color light module, the light receiving power of the color light module and the light power after light combination of all wave channels of passive wave combining and separating equipment at the first position, the second position, the third position and the fourth position, collecting the light power of an in-use wave channel and the light power of an idle wave channel, and sending the detected and collected data to a data processor; S2, enabling the data processor to analyze the 5G forward transmission network according to the received data; S3, performing graphical display. According to the method, a quality control means and an evaluation system of the 5G forward transmission network are formulated, and the data are displayed through legend, so that a user can clearly know the quality conditions of all wave channels of the whole 5G forward transmission network, and the method is visual and simple.

Description

technical field [0001] The invention relates to a 5G fronthaul network quality detection method, which belongs to 5G communication technology. Background technique [0002] A 4G base station usually includes four parts: BBU baseband processing unit (Building Base band Unite), RRU radio frequency processing unit (Radio Remote Unit), feeder and antenna. The BBU baseband processing unit is mainly responsible for signal modulation, and is used to complete functions such as channel encoding and decoding, modulation and demodulation of baseband signals, and protocol processing. At the same time, it needs to provide interface functions with upper-layer network elements. The RRU radio frequency processing unit is mainly responsible for radio frequency processing, which is the intermediate bridge between the antenna and the BBU baseband processing unit: when receiving the signal, the RRU radio frequency processing unit filters the radio frequency signal from the antenna, amplifies it...

Problems solved by technology

[0005] The quality of the fronthaul network directly affects the reliability of 5G network coverage and signal quality. At the same time, considering the product quality of multiplexer / demultiplexer equipment in the 5G fronthaul network and the fact that the 5G fronthaul network is a semi-active or passive network, the quality of network construction and maintenance cannot be guaranteed. The status of effective guarantees, and as the running time of the 5G fronthaul network goes on, the quality of the fronthaul network will also be affected by various factors; it is very urgent to improve the quality control and testing methods of the 5G fronthaul network and improve the efficiency of operation and maintenance

Existing technologies usually use instrumentation to collect various indicators of 5G fronthaul network quality, but the collected indicators are a lot of discrete data, it is difficult to make an intuitive display and evaluation of 5G fronthaul network quality, users get the indicator data Finally, it is difficult to judge whether there is a problem with the quality of the 5G fronthaul network, let alone know where the problem lies. This has brought great trouble to users
