Abstract
The present invention relates to cellular communications and in particular to a frequency spectrum shared by two cellular networks. The object is flexible utilization of the spectrum. This is achieved by a method wherein a first of the networks occupies part of the shared spectrum in relation to the traffic load in the first network. The first network informs a second of the networks on the extent the shared spectrum is occupied, for the second network to be free to use the shared spectrum outside the occupied part. The invention also relates to a RRM unit arranged for carrying out the inventions, to a BSC and to a radio base station adapted for carrying out the method. One advantage is that spectrum can be lent from an old system when a new system is introduced.
