Problems solved by technology

[0019] In the actual process of locating interference sources, since there are many sources of interference, it is necessary to use the above-mentioned methods in Table 3 to check various types of interference one by one, resulting in a complicated and time-consuming investigation process, and it is impossible to quickly locate the interference source
In addition, the above-mentioned traditional interference location method also requires high skill and experience of network optimization engineers, and the corresponding labor cost will be high

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The core idea of ​​the present invention is to accurately locate the interference type according to the cell traffic (ERL), cell-level interference band statistics (OUTB1) and carrier frequency-level interference statistics (trxinterf) counted by the system.

[0029] figure 1 It is a schematic flow chart of Embodiment 1 of the present invention, such as figure 1 As shown, this embodiment mainly includes:

[0030] Step 101. For each cell, calculate the interference reference index of the cell in each statistical cycle, and calculate the evaluation parameters of the cell in this statistical cycle according to the statistical results. The interference reference index includes: cell traffic Quantity ERL, cell-level interference band ...

Abstract

The invention discloses a recognition method for uplink interference types. The recognition method includes the steps that for each cell, interference reference indexes of the cell are counted in each statistics period, and evaluation parameters of the cell in the current statistics period are calculated according to the statistics result, wherein the interference reference indexes comprise cell telephone traffic ERL, cell-level interference band statistical values OUTB1 and carrier-frequency-level interference statistical values trxinterf, and the evaluation parameters comprise the standard deviation delta of carrier-frequency-level interference statistical values trxinterf of all carrier frequencies in the cell; for each cell, when each interference determining period is reached, the current interference type of the cell is determined according to the statistical values of the interference reference indexes and the evaluation parameters. The uplink interference types can be rapidly, effectively and accurately recognized by the adoption of the recognition method.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an identification method of uplink interference type. Background technique [0002] Mobile communication technology has entered a fairly mature stage. In the actual network optimization work, the uplink interference of the system has become an important problem that cannot be ignored in network optimization. Uplink interference has also become an important factor affecting the quality of network calls. There are many sources of uplink interference. From the source, it is mainly divided into external interference and internal interference. External interference mainly refers to the uplink interference caused by interference devices, civil systems, and other operator equipment; internal interference mainly refers to the internal interference caused by the system itself. The generated interference mainly includes the interference caused by the active and passive equipment a...
