Embodiment 1

[0033] figure 1 A flow chart of a method for detecting uplink external interference provided by an embodiment of the present invention, as shown in figure 1 As shown, including the following processes:

[0034] S101. Obtain the interference signal power arriving at the cell within N time granularities respectively, where N≥1, a positive integer.

[0035] The time granularity refers to a time unit, for example, 1 hour is 1 time granularity, or 2 hours is 1 time granularity. In this embodiment, one hour is set as one time granularity, and N=168, that is, the interference signal powers arriving at the cell in each hour of a week are respectively obtained, and a total of 168 interference signal powers are obtained.

[0036] Taking one of the time granularities as an example, the specific method of obtaining the interference signal power arriving at the cell within the time granularity may include the following two sub-steps S101a and S101b:

[0037] S101a. Obtain the uplink ser...

Abstract

The invention discloses an uplink external interference detection method and device and an uplink external interference source location method and device. The uplink external interference detection method includes: acquiring powers of interference signals reaching cells in N time granularities respectively; comparing the acquired powers of the interference signals reaching the cells in each time granularity with a first threshold, and counting the number of time granularities in which the powers of the interference signals are larger than the first threshold; comparing the counted number of time granularities with a second threshold; if the counted number of time granularities is larger than the second threshold, determining that the corresponding cells have uplink external interference. The uplink external interference source location method includes: determining all interfered cells having the uplink external interference by the uplink external interference detection method; determining the interfered cells influenced by the same interference source, from all interfered cells according to preset rules; according to the interfered cells influenced by the same interference source, calculating location information of the interference source. Through the adoption of the technical scheme, the technical problem that the traditional schemes are imperfect is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink external interference detection method, an uplink external interference detection device, an uplink interference source locating method and an uplink interference source locating device. Background technique [0002] In wireless networks, the common interference of base stations is divided into system interference and system interference. In-system interference is usually caused by base station planning, unreasonable parameter settings, and irregular engineering installation. External system interference is caused by some coexistence or co-site Interference between different frequency systems, repeaters, microwave communications, industrial electromechanical equipment, neon lights, signal lights, radio equipment, shielding equipment, etc. [0003] In the FDD (Frequency Division Duplexing, frequency division duplex, also known as full duplex) system, including CDMA (Cod...
