The service may evaluate geospatial, performance metric, and neighbor criteria data relating to overlap areas between source cells and candidate target cells. The service may calculate composite values for each candidate target cell and select the candidate target cell based on the composite value. The service may manage the mobility of end devices and associated mobility procedures on a sub-sector, sector, cell, and cluster of cell level. The service may reconfigure network devices and the end device to satisfy optimization, healing, and site planning measures. ## Claims ### Claim 1 A method comprising: obtaining, by a network device, geospatial data, performance metric data, and neighbor criteria data pertaining to a source cell and each candidate target cell of an overlap area relative to the source cell;
