Embodiment 1

[0025] Based on the above basic ideas, the method flow chart of a cell interference processing method provided by the embodiment of the present invention is as follows figure 1 As shown, it specifically includes the following steps:

[0026] Step 11. Receive the traffic statistics report of the cell.

[0027] Step 12, by analyzing the received traffic statistics report of each cell, determine the interfered cell whose degree of interference satisfies the specified condition.

[0028] Step 13. For each determined interfered cell, determine whether there is a candidate cell whose coverage area is the same as that of the interfered cell and is a non-interfered cell;

[0029] Step 14. When the judgment result is yes, according to the interference signal level determined for the interfered cell, adjust the cell reselection parameter value and the cell handover parameter value of the interfered cell and the candidate cell respectively, so that the The victim cell absorbs a high le...

Embodiment 2

[0044] A method for processing cell interference provided by an embodiment of the present invention is specifically described below in combination with specific examples.

[0045] For the 900M cell that is susceptible to interference, the method flow chart of a cell interference processing method provided by the embodiment of the present invention is as follows image 3 shown.

[0046] Step 21: Receive the traffic statistics report of each 900M cell, and determine the 900M cell with high interference and high call drop according to the interference level and call drop situation of each interfering cell recorded in the traffic statistics report.

[0047] Step 22. For the 900M cell determined in step 21, perform an external interference source location operation. For example, you can use a frequency scanning instrument to scan and troubleshoot the external interference source, and determine the 900M cell where the interference source cannot be located.

[0048] Step 23, for eac...

Abstract

The invention discloses a method and device for handling cell disturbance. The method and device are used for solving the problems that in the prior art, when cell disturbance under the coverage of a double-frequency network is handled, traffic loads of cells under the coverage of the double-frequency network are unbalanced, and the overall traffic bearing capacity is lowered. The method for handling cell disturbance comprises the steps that by analyzing received traffic statistic reports of all the cells, the disturbed cells with the disturbed degree meeting specified conditions are determined; after undisturbed candidate cells with the same coverage area as the disturbed cells are determined, according to the interference signal level determined for the disturbed cells, reselection parameter values of the disturbed cells and the candidate cells and cell switching parameter values are adjusted respectively so that the disturbed cells can absorb high level traffic with the level higher than the interference signal level and the candidate cells can absorb relatively low level traffic.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cell interference processing method and device. Background technique [0002] In the mobile communication system, due to the influence of external interference such as privately installed repeaters and signal jammers in some cells, the signal quality in the coverage area will deteriorate, which will reduce the call quality between users in the coverage area and cause call drop. rate increases, ultimately affecting user experience. Judging from the currently known characteristics of external interference sources, the currently interfered cells are basically 900M cells. In the prior art, for such a cell subject to external interference, the most effective solution is to locate and eliminate the external interference source, and eliminate the interference effect. However, this method of locating and eliminating external interference sources has problems such...
