Currently, a self-organizing network mainly has automatic functions such as automatic configuration, automatic optimization (including automatic neighbor optimization, load balancing optimization, capacity and coverage optimization, and the like), and automatic discovery, and these functions may also be referred to as SON functions.
ANR is one of the most widely used SON functions, and is capable of automatically establishing and updating a neighbor relation, that is, automatically establishing and adaptively adjusting a neighbor list according to an operation state of a radio network and radio data collected by a User Equipment (UE) and a radio base station (eNB), so as to support cell handover, and mainly include functions of neighbor addition, neighbor deletion, neighbor management, and the like, thereby ensuring service continuity of the user equipment, and enabling a user to always provide a stable network signal to the user regardless of how the user moves and how a radio environment changes. In the actual working process, it is found that, because the ANR performs neighbor optimization only based on the switching requirement, and does not consider the relative position of the neighbor, there are problems of cross-region coverage, addition of a large number of redundant neighbors, neighbor missing, and the like, and it is seen that the reliability of the ANR technique is not high, and therefore, the neighbor relation needs to be further optimized to improve the reliability of the neighbor relation.
Based on this, an embodiment of the present invention provides a neighboring cell optimization method, which determines a neighboring cell optimization scheme based on Measurement Report (MR) data and location information reported by a user terminal, so as to improve reliability of a neighboring cell relationship.

The user terminal 102, the server 103, and the manager terminal 104 are connected to the base station 101 via a network, and the server 103 and the manager terminal 104 are connected to each other via a network. The user terminal 102 reports the MR data and the location information of the user terminal to the base station 101, the server 103 obtains the MR data and the location information of the user terminal from the base station, determines neighbor optimization information according to the MR data and the location information of the user terminal, and sends the neighbor optimization information to the manager terminal 104.

The MRO data includes Reference Signal Receiving Power (RSRP) of the main serving cell, RSRP of the neighboring cell, a public gateway interface of the main serving cell, a physical cell identifier, and location information of the user terminal that reports the MR data. One main service cell may correspond to a plurality of neighboring cells, and may include not only neighboring cells configured with neighboring cell relationships with the main service cell, but also neighboring cells not configured with neighboring cell relationships with the main service cell.

In the embodiment of the invention, the server acquires the standing book information from the standing book information storage, and determines the average station spacing according to the standing book information.
The average inter-station distance is determined as follows: for any cell A, the corresponding adjacent cell when the cell A is taken as the main cell, the position information of the cell A and the position information of the corresponding adjacent cell are determined according to the standing book information, and the position information can be latitude and longitude information. Suppose that cell a has N neighbor cells in total, wherein the N neighbor cells do not include co-sited neighbor cells. Respectively obtaining the distance between the cell A and any adjacent cell according to the position information of the cell A and the position information of the N adjacent cells, specifically, the cell A and the adjacent cell BjDistance d ofjIs dj＝r×arccos(sina2×sinbj2+cosa2×cosbj2×cos(bj1-a1) R is the average value of the radius of the earth, a)1Arc corresponding to the latitude of cell A, a2Radian corresponding to longitude of cell A, bj1Is cell BjArc corresponding to latitude of (b)j2Is cell BjCorresponds to radians. In the N adjacent cells, if N is larger than 3, determining 3 adjacent cells which are closest to the cell A, and taking the average value of the distances between the cell A and the 3 adjacent cells as the average station spacing of the cell A, and if N is smaller than 3, taking the average value of the distances between the cell A and the N adjacent cells as the average station spacing of the cell A.
