Such communication system, the embodiment of the present application not limit.
The embodiment of the present application provides a kind of interference estimation method and is applied in communication network.In the following, we will be with described
Communication network be LTE network for, the interference estimation method is described in detail.The interference estimation method can be by appointing
Computer equipment of anticipating executes.As shown in Figure 1, the method includes S101-S106:
S101, the work ginseng information and measurement report MR for obtaining the communication network.
Wherein, the communication network is LTE network.The work ginseng information includes: cell name, cell number (cell
ID, CI), Location Area Code (location area code, LAC), cell longitude and latitude, deflection.It include: that cell is compiled in the MR
Number, cell name, frequency point, Physical Cell Identifier (Physical Cell Identifier, PCI), RSRP.
S102, the position of the main serving cell and the position of the adjacent area are determined according to work ginseng information.
Wherein, the main serving cell is to need to carry out the cell of interference assessment in the communication network.The adjacent area is
Cell in main serving cell coverage area described in the communication network.
Specifically, including cell name, the CI, LAC, cell longitude and latitude, deflection of each cell in the work ginseng information.Root
The geographical location of each cell is determined according to the longitude and latitude of each cell in work ginseng information.
S103, interference ratio between the main serving cell and each adjacent area is determined according to the MR.
Wherein, the interference ratio is that the signal reception power of the main serving cell and the signal of the adjacent area receive function
The ratio of rate.
Specifically, obtained from the MR main serving cell Reference Signal Received Power RSRPsc and the adjacent area
Reference Signal Received Power RSRPnc.
If the RSRPsc subtracts the RSRPnc greater than first threshold, ignore the main serving cell and the adjacent area
Between interference ratio.
If the RSRPsc subtracts the RSRPnc greater than second threshold and is less than or equal to first threshold, the main service
Interference ratio between cell and the adjacent area are as follows:
If the RSRPsc is less than or equal to the RSRPnc, the interference ratio between the main serving cell and the adjacent area
Example are as follows:
Illustratively, the first threshold is 6db, and the second threshold is 0db.
In current LTE network, in the case where RSRPsc > RSRPnc, the interference ratio between cell is bigger, main clothes
The interference for the adjacent area that business cell is subject to is bigger.Generally when inter-cell interference ratio is greater than 16.7%, it is believed that main serving cell
The interference for the adjacent area being subject to is larger;Need to carry out the adjacent area interference monitoring or adjustment of emphasis.If inter-cell interference ratio
When example is greater than 33.3%, it is believed that the serious interference for the adjacent area that main serving cell is subject to needs as soon as possible to the main serving cell
Or adjacent area optimizes, to reduce interference of the adjacent area to main serving cell.If RSRPsc≤RSRPnc;Illustrate adjacent small
There are the cell that signal strength is higher than main serving cell in area, but do not switch, need to detect whether to lack there are adjacent area or
The problems such as person adjacent area access is difficult.
S104, the coverage area of the main serving cell is divided into multiple regions according to preset rules, and determined each
Region belonging to the adjacent area.
Specifically, the method for establishing 360 degree of cover jamming models are as follows: centered on the main serving cell, according to
The coverage area of the main serving cell is divided into multiple subregions by predetermined angle.The coverage area of the main serving cell is drawn
It is divided into n-layer;Wherein, for each subregion, will be apart from the region division that the main serving cell is the first pre-determined distance
First layer;It is by the first pre-determined distance is greater than less than the region division of the second pre-determined distance apart from the distance of the main serving cell
The second layer;It is drawn until the (n-1)th pre-determined distance will be greater than apart from the distance of the main serving cell less than the region of the n-th pre-determined distance
It is divided into n-th layer.According to the position of each adjacent area determine each adjacent area belonging to region.

The coverage area of serving cell carries out subregion, for example, using the azimuthal neutrality line of antenna in cell as starting point (i.e. 0 degree), with 30 degree
For interval, which is uniformly divided into 12 subregions.Respectively each partition number, for example, with the main lobe of antenna
The coverage area in area, secondary lobe area and back lobe area carries out subregion division.The region that antenna main lobe area is covered (is located at 0 degree of -60 degree
Between region and positioned at 300 degree -360 degree between region) be labeled as the first subregion, the second subregion, the 11st subregion and the tenth
Two subregions.Antenna sidelobe area is covered region (positioned at 60 degree -120 degree between region and positioned at 240 degree -300 spend between
Region) it is labeled as third subregion, the 4th subregion, the 9th subregion and the tenth subregion.Antenna backlobe area footprint area (is located at
Region between 120 degree of -240 degree) it is labeled as the 5th subregion, the 6th subregion, the 7th subregion and octant.Then to the master
The coverage area of serving cell is layered, for example, the 0th layer will be divided into station neighboring community, a general website includes three
A cell, three cells complete the signal covering to coverage area jointly, can be considered as not doing mutually between three cells
It disturbs.By first layer is determined as using distance r as the region of radius centered on the main serving cell, (distance r can be according to covering
Lid scene as: dense city, the difference in city, suburb and rural area etc. take different distances, such as it is general in dense city r
100 meters are taken, generally takes 200 meters in general city r).Region centered on main serving cell between r and 2r is second
Layer.Centered on main serving cell, the region other than the region that radius is 2r is third layer.
S105, according to interference ratio-dependent each region between the main serving cell and each adjacent area to described
The interference coefficient that main serving cell generates.
Specifically, the interference ratio summation to adjacent area described each of in the first subregion determines first subregion to described
The interference coefficient of main serving cell;Wherein, first subregion is any region in the coverage area of the main serving cell.
Illustratively, during primary specific interference assessment, 360 are established to the main serving cell of number 410689_1
After degree covering partition model, the interference in its first subregion is assessed.Join information by public affairs to determine locating for each adjacent area
