Method and apparatus for serving cell identification includes: receiving inputs that include geo-located data collected over a period for a plurality of cells in RAN; determining each cell included in each grid of a predetermined size based on the geo-located data; determining Received Signal Received Power (RSRP) values for each cell having the predetermined size; determining a median cell RSRP for each cell of a grid; determining from the geo-located data a number of data samples per cell for each grid having the predetermined size; determining a cell ranking for each of the cell in the grids having the predetermined size based on the number of data samples and the median cell RSRP; determining a highest-ranking cell in each grid based on the cell ranking; labeling the highest-ranking cell as a Main Server (MS); and labeling all other cells in a corresponding grid as a Non-Main Server (NS).

Apparatus and method for serving cell identification

An acceptable coverage limit of a base station is identified by retrieving a list of cells that are served by a first base station. Grids are generated from the first base station to a predetermined threshold distance. A plurality of selected grids is identified between an acceptable coverage limit and a threshold distance. An average reference signal is determined from the plurality of selected grids. An evaluation is made regarding whether the first base station is the dominant cell in each of the selected grids. The number of grids the selected grids where the first base station is the dominant cell site is determined based on a dominant carrier threshold. A column of grids is determined where the first base station is not the dominant cell site. An acceptable coverage limit of the cell is determined based on the distance from the first base station and the column of grids.

Acceptable coverage limit determination

A booming cell start distance and recommended electronic tilt is identified by retrieving a list of cells served by a first base station. A plurality of grids is generated from the first base station to a predetermined threshold distance. A plurality of selected grids is identified between an acceptable coverage limit and a threshold distance. An evaluation is made regarding whether the first base station is not the dominant cell in each of the selected grids based. The number of grids where the first base station is not the dominant cell site is determined based on a dominant carrier threshold. A column of grids where the first base station is no longer the dominant cell site is determined based on the dominant carrier threshold. A bad booming distance of the cell is determined based on the distance from the first base station and the determined column of grids.

Electronic tilt coverage

A cell range determination is made by determining a sector straddling an azimuth line of a first base station with a center at the coordinates of a first base station. The sector is divided into a plurality of subsectors. A nearest neighbor base station is determined in each of the plurality of subsectors. A set of coordinates is determined for the nearest neighbor base station. An average distance between the nearest neighbor base stations is determined. A bearing angle difference between the nearest neighbor base station and the first base station is determined based on the set of coordinates of the nearest neighbor base station. A gain is determined for each of the plurality of subsectors based on the bearing angle difference. A cell range is determined for the first base station based on the gain.

Automatic cell range

A booming cell site is identified in a cloud native environment by retrieve an on-air base station from a site database, retrieve a timing advance distribution (TAD) key performance indicator data for a cell site served by the on-air base station from the list, determine a count of configured gaps for the cell site in the timing advance distribution key performance indicator data, determine a count of booming samples that lie beyond the configured count of gaps for the cell site based on the timing advance distribution key performance indicator data, determine a sum of the timing advance distribution key performance indicator data available for the cell site, and determine the percentage of booming cells based on the count of booming samples and the sum of the timing advance distribution key performance indicator.
