In a cellular communications network, it may be desirable for a large number of basestations to share one or a small number of scrambling codes. When a basestation identifies a desired scrambling code, which is also being used by another nearby basestation, steps are taken such that a location area update is triggered whenever a mobile communications device moves from a coverage area of the nearby basestation into a coverage area of said basestation. Further, the basestation establishes a first cell, using the desired scrambling code, and also establishes a second cell also served by the basestation, using a second scrambling code. By ensuring that mobile devices are preferentially served by the second cell, the possibility of interference with the nearby basestation is reduced.
