Abstract
In one aspect, the teachings herein provide an enhanced inter-base-station interface and associated processing in which a base station receives a message from a neighboring base station that zero served PLMNs are available in a neighboring cell. In response to receiving that message, the base station removes the neighboring cell from its neighbor list, or otherwise marks the neighboring cell as unavailable, but advantageously does not discard any network performance data accumulated or otherwise generated for that neighboring cell. Correspondingly, should the base station receive a subsequent message indicating that one or more served PLMNs have become available in the neighboring cell, it restores the neighboring cell to its neighbor list and reinstates links or associations, as needed, to the retained network performance data.
