The existing adjacent cell planning and checking method is mainly divided into two application scenes: planning adjacent areas among systems in an LTE new station system; and checking the adjacent cells between systems in the existing network LTE cell system. The technical scheme of planning the inter-system neighbor cell in the LTE new station system is mainly based on the linear distance between LTE cells, LTE and GSM cells and the normal angle of an azimuth angle, a threshold is set (for example, the distance is less than 1KM, and the normal angle of the azimuth angle is less than 30 degrees), and the threshold is the neighbor cell to be matched; the technical scheme for checking the neighbor cells of the same system of the existing network LTE cell mainly depends on the following steps: a. setting a threshold for linear distance and azimuth normal included angle among LTE cells, LTE and GSM cells, and satisfying the requirement of adding adjacent cells to the threshold and otherwise deleting the adjacent cells; b. neighbor cell handover statistics for assisting in judging the reasonability of the neighbor cells already configured in the current network (for example, deleting the neighbor cells with the handover statistics frequency of 0 or the handover success rate of less than 10%); c. and based on the test problem event and the user complaint, finding the missing neighbor cell.

Fig. 1 is a schematic flow chart of a method for checking neighboring cell planning in an embodiment of the present invention, where an execution subject of the embodiment is a server, and the method includes the following steps:

s1: and obtaining a correlation value between the main cell and each adjacent cell according to the overlapping coverage area between the cell pairs and the switching statistical data.

Specifically, when the primary cell and the neighboring cell belong to the same-system neighboring cells of the LTE cell, that is, when both the primary cell and the neighboring cell belong to the LTE cell, a correlation value between the primary cell and each neighboring cell is obtained according to an overlapping coverage area between cell pairs and handover statistical data; and when the main cell and the adjacent cell belong to the adjacent cells between systems in the LTE new station system, obtaining correlation values between the main cell and each adjacent cell according to the overlapping coverage area between the cell pairs, the event triggered measurement report MRE, the sample type measurement report MRO and the switching statistical data.

Understandably, the larger the correlation value between the primary cell and the neighboring cell is, the higher the probability that the neighboring cell is the neighboring cell to be configured of the primary cell is. Therefore, the neighbor cell can be evaluated according to the correlation value.

The working parameter algorithm based on the inter-cell overlapping coverage area and the switching statistical data is used for planning the inter-system neighbor cells in the LTE new station system, and meanwhile, the measurement data such as MRE, MRO, GSM MR and the like reported by the actual measurement of the current network of a user are added in the optimization scene of the inter-system neighbor cells of the LTE cell of the current network, so that the problem of user perception of the fit user can be solved, and the requirement of the scheme on the accuracy of the working parameters can be reduced.

Wherein NUM_MAXTo add the maximum number of neighbor cells, i represents the ith neighbor cell, and 0 < i ≦ total number of neighbor cells.

Therefore, the embodiment determines the correlation value based on the overlapping coverage area and the switching statistical data, and determines the adjacent area table to be configured based on the correlation value, so that the problem of use perception of a fit user can be solved, and the requirement of a scheme on the accuracy of the working parameters can be reduced; the invention can excavate the missing adjacent area before the event happens, thus realizing the precaution.

It should be noted that the steps S11 to S14 are only applicable to the inter-system neighbor cell planning scenario in the LTE new station system, that is, the primary cell and the neighbor cell are an LTE cell and a GSM cell, respectively. If the scenario is planned for the neighboring cells of the same cell system, if the primary cell and the neighboring cells are both LTE cells, only S11 and S14 are considered, and the larger value of the first correlation value calculated in S11 and the fourth correlation value calculated in S14 is selected as the final correlation value between the primary cell and each neighboring cell, without considering steps S12 to S14.

S42: and matching the adjacent region table to be configured of the main cell with the existing network configured adjacent region table of the main cell, acquiring adjacent cells which exist in the adjacent region table to be configured and do not exist in the existing network configured adjacent region table, selecting the adjacent cell of which the distance from the main cell is greater than a second preset distance, and generating an over-long missing configuration adjacent region table.

Specifically, the neighbor table to be allocated to the primary cell a is matched with the neighbor table allocated to the current network of the cell a, and the distance between the primary neighbor cell and the primary neighbor cell existing in the neighbor table to be allocated but not existing in the neighbor table allocated to the current network is obtained>DIST_THR1And summarizing and generating the far missing-configuration neighbor cell list. Wherein DIST_THR1The threshold value of the distance between the adjacent regions is omitted for too far, and the threshold value can be set according to an actual system.

S43: and matching the adjacent region table to be allocated of the main cell with the existing network allocated adjacent region table of the main cell, acquiring adjacent cells existing in the adjacent region table to be allocated and the existing network allocated adjacent region table, selecting adjacent cells of which the distance from the main cell is greater than a third preset distance, and generating an excessively far allocated adjacent region table.

Specifically, the neighbor table to be allocated to the primary cell a is matched with the neighbor table allocated to the current network of the cell a, and the distances between the primary and the neighboring cells, which exist in the neighbor table to be allocated and also exist in the neighbor table allocated to the current network, are obtained>DIST_THR2The too far allocated neighbor list is generated by summarizing the cell pairs. Wherein DIST_THR2The threshold value of the distance of the neighboring cell allocated too far can be set according to the actual system.

Specifically, the neighbor table to be allocated to the main cell a is matched with the neighbor table already allocated to the current network of the cell a, and the neighbor table to be allocated is obtained, wherein the neighbor table to be allocated does not exist but exists in the current network allocated neighbor table, and the SMM exists_COR<SMM_CORTHR&&Handover success rate<HO_THRThe cell pairs of (2) are summarized to generate a back-to-neighbor list. SMM_CORTHRIf the ratio threshold value is the overlapping coverage area ratio between the macro station and the macro station, the main cell A and the neighbor cells in the back neighbor cell list are the macro cells; HO_THRThe switching success rate threshold value can be set according to an actual system.

Therefore, the embodiment realizes the check of the abnormal adjacent cells such as the redundancy, the too far, the back and the like of the current network through the combination of various thresholds and conditions so as to eliminate the adjacent cells with various problems and ensure the switching function between the output missed-matching adjacent cell pairs.
