Abstract

A base station includes an emulation controller (20) configured to receive signals indicating that another base station in an active mode managing a cell, having a predetermined cell identity and coverage area, will go into an idle mode and no longer manage the cell, and to determine terminal activity in the cell. A baseband processing unit (18) is connected to the emulation controller (20) and configured to emulate the active mode of the other base station by taking over management of the cell, in at least part of its coverage area, using the same cell identity.
