1. A method of forming a neighbor cell list in a base station of a cellular communications network, the method comprising, at periodic intervals, and for specified durations:
- requesting at least one wireless device that is in connected mode with the base station to report a unique identifier for each other base station that it is able to detect;
receiving reports from each wireless device that is in connected mode with the base station;
operating with a neighbor cell list compiled on the basis of the received reports; and
reporting instances where one or more of the wireless devices in connected mode reports that it can detect signals from two other base stations that are using a same physical cell identifier as each other, but have different unique identifiers.
