1. An apparatus configured to be employed in a Core Network of a wireless system, comprising:
one or more processors configured to:
collect, for a cell in a Radio Access Network, performance measurements of a plurality of neighbor cells of the cell;
determine, based at least on the performance measurements of the plurality of neighbor cells, whether to update a Neighbor Relation Table (NRT) of the cell; and
perform, in response to a determination to update the NRT of the cell, an action for updating the NRT of the cell;
wherein collecting the performance measurements is at least in response to determining that a number of failed radio resource control (RRC) connections or hand over failures from a combination of the cell and one or more additional cells exceeds a threshold number.
