Problems solved by technology
However, due to the above method of identifying and locating external interference, network maintenance personnel are required to go to the site to check for external interference, and the entire process of checking requires manual repeated frequency scanning tests and positioning analysis around the interference cell, so it takes a lot of time. It takes a lot of energy and time to finally find out the location area where the external interference source is located, and the accuracy cannot be guaranteed
[0004] It can be seen that the methods for identifying and locating external interference sources in the prior art GSM network rely on manual operations, so there is a problem that the efficiency and accuracy of positioning cannot be guaranteed

Embodiment Construction
[0031] The basic idea of the present invention is: according to all the MRs currently recorded, calculate the incoming interference of each cell; locate each MR to the corresponding grid area, and use all the MRs corresponding to each grid area and the location of the grid area A grid interference matrix is established for the incoming interference of the cell; and an external interference location area is located according to the grid interference matrix.
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] The method for locating external interference proposed by the present invention, such as figure 1 shown, including the following steps:
[0034] Step 101: Calculate the incoming interference of each cell according to all currently recorded MRs.
[0035] Specifically, the network management device establishes the interference matrix of each cell managed by itself accor...

The invention discloses a method for locating external interference, which includes: calculating the incoming interference of each cell according to all currently recorded measurement reports (MRs); locating each MR to a corresponding grid area, using each grid Establish a grid interference matrix based on the incoming interference of all MRs corresponding to the grid area and the cell where the grid area is located; locate the external interference location area according to the grid interference matrix. The invention also discloses a device for locating external disturbances at the same time. By adopting the invention, manual operation can be avoided, thereby ensuring the efficiency and accuracy of locating external disturbances.
Description
technical field [0001] The invention relates to an interference location technology in the field of mobile communication, in particular to a method and device for locating external interference. Background technique [0002] In the Global System for Mobile Communications (GSM, Global System for Mobile Communications) network, external interference is an important factor affecting indicators such as call quality, call drop rate, and connection rate. Common sources of external interference include external jammers, Code Division Multiple Access (CDMA, Code Division Multiple Access) base stations, fake radio stations, and thermal noise from electrical appliances. These external interferences will affect GSM network indicators and user perception. [0003] At present, the method of identifying and locating external interference in the GSM network is usually: network maintenance personnel check the distribution of interference on idle channels in combination with the cell interfe...
