Description

Technical Field

[0001] The invention belongs to the field of radio communications, and in particular relates to a configuration method and a configuration device for an unknown neighboring area. Background Art

[0002] With the continuous development of wireless networks, people have higher and higher requirements for network performance, such as higher quality video calls, faster speeds, and higher definition, etc. Limited by the fact that UE terminals currently do not support CGI (Cell Global Identifier) ​​measurement, when a UE terminal identifies an unknown NR (New Radio) neighboring cell, it cannot add the neighboring cell to the neighboring cell list because it cannot obtain the CGI of the neighboring cell, resulting in the failure of the UE terminal to switch cells, which ultimately affects the normal use of users.

[0003] At the same time, in the current NSA or SA networking scenarios, the work methods for adding 5G neighboring cells to 4G / 5G cells are single, and the workload of manually optimizing neighboring cells is large and cumbersome. In addition, there are many cases of missed configuration and unreasonable configuration, which lead to problems such as low success rate of neighboring cell switching. Therefore, it is urgent to identify the CGI of the unknown neighboring cell through the MR (Measurement Report) reported by the UE terminal, and then improve the efficiency of neighboring cell optimization in actual applications through the ANR (Automatic Neighbor Relation) function. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a method and device for configuring an unknown neighboring area.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] Technical solution 1:

[0007] A method for configuring an unknown neighboring cell, comprising:

[0008] Receive the unknown neighboring cell PCI and frequency reported by the UE terminal;

[0009] Search all cells in the entire network that have the same PCI and frequency as the unknown neighboring cells to obtain a cell set;

[0010] Determine the latitude and longitude range of the search area for unknown neighboring cells;

[0011] Filtering cells in a search area of ​​an unknown neighboring area from the cell set to obtain a filtered cell set;

[0012] Calculate the distance between each cell in the filtered cell set and the center point;

[0013] The cell closest to the center point is taken as the final neighboring cell of the serving cell, and the neighboring cell information of the final neighboring cell is added to the neighboring cell list.

[0014] Furthermore, the specific method for determining the latitude and longitude range of the search area of ​​the unknown neighboring area is:

[0015] Determine the longitude and latitude information of the center point of the service cell;

[0016] A contour line is drawn with the longitude and latitude of the center point as the center and the distance parameter of the unknown neighboring area search range as the boundary to obtain the longitude and latitude information of the unknown neighboring area search area.

[0017] Furthermore, the method for determining the position of the center point is:

[0018] When the serving cell has no formal neighboring cell before receiving the unknown neighboring cell PCI and frequency reported by the UE terminal, the center point is the serving cell;

[0019] Assume that the serving cell is A, the center point is A', and the longitude and latitude of the serving cell A are Coordinate_A = (logA, latA); Assume that the longitude and latitude of the center point are Coordinate_Center = (logA', latA'); then logA' = logA; latA' = latA;

[0020] When the serving cell has one formal neighboring cell before receiving the unknown neighboring cell PCI and frequency reported by the UE terminal, the center point is the midpoint of the line connecting the serving cell and the formal neighboring cell;

[0021] Suppose the serving cell is A, the center point is A', and the longitude and latitude of the serving cell A are Coordinate_A = (logA, latA); suppose the formal neighboring area is A1, and the longitude and latitude of the formal neighboring area A1 are Coordinate_A1 = (logA1, latA1); the longitude and latitude of the center point are Coordinate_Center = (logA', latA'); then, logA' = (logA+logA1) / 2; latA' = (latA+latA1) / 2;

[0022] When the serving cell has two formal neighboring cells before receiving the unknown neighboring cell PCI and frequency reported by the UE terminal, the center point is the centroid of the triangle formed by the serving cell and the two formal neighboring cells;

[0023] Suppose the service cell is A, the center point is A', the longitude and latitude of the service cell A is Coordinate_A = (logA, latA); suppose two formal neighboring areas are A1 and A2, the longitude and latitude of the formal neighboring area A1 is Coordinate_A1 = (logA1, latA1), the longitude and latitude of the formal neighboring area A1 is Coordinate_A2 = (logA2, latA2); the longitude and latitude of the center point is Coordinate_Center = (logA', latA'); then, logA' = (logA+logA1+logA2) / 3; latA' = (latA+latA1+latA2) / 3;

[0024] Before receiving the unknown neighboring cell PCI and frequency reported by the UE terminal, when the serving cell has N formal neighboring cells, N>2, two formal neighboring cells closest to the serving cell are selected, and the center point is the centroid of the triangle formed by the serving cell and the two nearest formal neighboring cells;

[0025] Suppose the service cell is A, the center point is A', the longitude and latitude of the service cell A are Coordinate_A = (logA, latA); suppose the two nearest formal neighboring areas are A1 and A2, the longitude and latitude of the formal neighboring area A1 are Coordinate_A1 = (logA1, latA1), and the longitude and latitude of the formal neighboring area A1 are Coordinate_A2 = (logA2, latA2); the longitude and latitude of the center point are Coordinate_Center = (logA', latA'); then, logA' = (logA+logA1+logA2) / 3; latA' = (latA+latA1+latA2) / 3.

[0026] Furthermore, before drawing a contour line with the longitude and latitude of the center point as the center and the search range of the unknown neighboring area as the boundary, it is necessary to first set a distance parameter of the search range of the unknown neighboring area.

[0027] Furthermore, the search range of the unknown neighboring cell is set according to the deployment density of the base station, and the distance parameter of the unknown neighboring cell search area is sufficient to ensure that the serving cell can have at least one neighboring cell.

[0028] Furthermore, the contour line is a square contour line, the four sides of the square are respectively parallel to the plane where the longitude lines or latitude lines are located, and the distance parameter of the unknown neighboring area search area refers to the distance from the center of the square contour line to the border.

[0029] Furthermore, the latitude and longitude (logX, latX) of any corner of the square is calculated as follows:

[0030] Assume that any angle on the square is angle X, the azimuth angle of angle X is angle, the longitude and latitude of the center point of the square is: Coordinate_Center = (logA', latA'), the search range of the unknown neighboring area is Distance, the earth's polar radius is Rj; the earth's equatorial radius is Rc, and pi is PI;

[0031] Then, double dx=distance*sin(angle*PI / 180);

[0032] double dy=distance*cos(angle*PI / 180);

[0033] double aEc=Rj+(Rc-Rj)*(90-latA') / 90;

[0034] double aEd=aEc*cos(latA'*PI / 180);

[0035] double logX=(dx / aEd+logA'*PI / 180)*180 / PI; double latX=(dy / aEc+latA'*PI / 180)*180 / PI;

[0036] Furthermore,

[0037] Taking the azimuth angle corresponding to the true north direction as 0 degrees, the azimuth angle of the upper left corner B of the square is angle=LEFT_TOP_ANGLE=-45 degrees; the azimuth angle of the lower right corner C of the square is angle=RIGHT_BOTTOM_ANGLE=135 degrees.

[0038] The search area of ​​the unknown cell is indicated by the longitude and latitude of the upper left corner and the lower right corner of the square, and the search area of ​​the unknown cell is: the longitude and latitude of the upper left corner B is: Left_Top_Coordinate = (logB, latB);

[0039] The latitude and longitude of the lower right corner C is: Right_Bottom_Coordinate = (logC, latC);

[0040]

[0041]

[0042]

[0043]

[0044] Furthermore, after calculating the distance between each cell and the center point in the filtered cell set, it is necessary to sort the cells according to the calculation results to obtain a sorted cell set.

[0045] Furthermore, the PCI and frequency of the unknown neighboring cell reported by the UE device are presented in the form of an MR measurement report.

[0046] Furthermore, when the neighbor information of the final neighbor is added to the neighbor list, it is automatically added through the automatic neighbor relation ANR.

[0047] Technical solution 2:

[0048] A device for configuring an unknown neighboring area, comprising:

[0049] A setting module is used to set the search range of unknown neighboring areas;

[0050] A receiving module, used to receive the PCI and frequency of an unknown neighboring cell reported by a UE device;

[0051] The search module is used to search all cells in the entire network that have the same PCI and frequency as the unknown neighboring cells to obtain a cell set;

[0052] A determination module is used to determine the longitude and latitude information of the center point of the serving cell, draw a contour line with the longitude and latitude of the center point as the center and the search range of the unknown neighboring area as the boundary, and obtain the longitude and latitude information of the unknown neighboring area search area;

[0053] A filtering module, used to filter out cells in a search area of ​​unknown cells from a set of cells;

[0054] A screening module is used to calculate the distance between each cell in the filtered cell set and the center point, and find the cell closest to the center point;

[0055] The configuration module is used to use the cell closest to the center point as the final neighboring cell of the serving cell and add the neighboring cell information to the neighboring cell list.

[0056] Further, the screening module includes: a calculation submodule, which is used to calculate the distance between each cell in the filtered cell set and the center point;

[0057] The sorting submodule is used to sort according to the calculation results, obtain a sorted cell set, and determine the cell closest to the center point.

[0058] Compared with the prior art, the present invention has the following beneficial effects:

[0059] The wireless communication network system is a complex network. The correctness of the configuration of the adjacency relationship between cells is related to the success rate of cell switching generated during the movement of the UE terminal, and thus to the stability of the entire network. However, when the adjacency relationship is configured manually, it is difficult, costly, and easy to miss configuration. In the case where the UE terminal can only detect the PCI frequency CGI of the unknown neighboring cell, we propose a new method for determining the unknown neighboring cell, that is, determining the unknown neighboring cell information based on the MR measurement of the UE terminal, which can solve the time-consuming, labor-intensive and inaccurate problems of manual configuration.

[0060] The present invention provides a method combining intelligence with user control. The user sets different distance parameters for different cell sizes and performs automatic identification of neighboring cells. The effect of the preparedness of the identified neighboring cells can be controlled to meet the needs of different scenarios.

[0061] The present invention can automatically complete the identification of unknown neighboring areas after neighboring area identification is performed in the early stage of network deployment or during network optimization, and automatically trigger the neighboring area adding function, so as to improve the operation and maintenance efficiency, reduce the operation and maintenance investment, and improve the network performance.

[0079] As a preferred embodiment of a method for configuring an unknown neighboring area of ​​the present invention, the method for determining the position of the center point is:

[0080] When the serving cell has no formal neighboring cell before receiving the unknown neighboring cell PCI and frequency reported by the UE terminal, the center point is the serving cell;

[0081] Assume that the serving cell is A, and the longitude and latitude of the serving cell A is Coordinate_A=(logA, latA); Assume that the longitude and latitude of the center point is Coordinate_Center=(logA', latA'); then logA'=logA; latA'=latA;

[0137] Because in this embodiment, before receiving the unknown neighboring cell PCI and frequency reported by the UE terminal, when the serving cell has no formal neighboring cell, the center point is the serving cell;

[0138] Assume that the serving cell is A, the center point is A', and the longitude and latitude of the serving cell A are Coordinate_A = (logA, latA) = (116.952736, 34.264648); Assume that the longitude and latitude of the center point A' are Coordinate_Center = (logA', latA') = (logA, latA) = (116.952736, 34.264648);

[0145] 6. Calculate the distance between each cell and the center point in the filtered cell set Nbars' and sort them.

[0146] The distance from the center point A' to the cell B: distanceA'B = 5597.587783971948

[0147] The distance from the center point A' to the cell D: distanceA'D = 4525.356106002652

[0152] The sorted cell set Nbrs” = {H, D, G, J, B, E}, so cell H is closest to the center point;

[0153] 7. Take cell H as the final neighboring cell of the serving cell, and automatically add the neighboring cell information to the neighboring cell list through the automatic neighbor relation ANR.
