Claim:
1. A method in a configuration node of a cellular network for selecting, from a set of channels of at least one primary system, at least one channel for allocation to base stations of the cellular network, the method comprising: receiving, from a database, a set of channels of the at least one primary system; observing a quality ranking of the channels of the received set of channels; determining an optimal number of channels for the cellular network on the basis of the ranked set of channels such that a signal quality in the cellular network is optimized; and selecting, from the received set of channels on the basis of the quality ranking and the determined optimal number of channels, at least one channel for allocation to base stations of the cellular network; determining a signal quality for a number of channels; increasing the number of channels and determining a further signal quality for the increased number of channels until a determined further signal quality is worse than a signal quality associated to the one or more numbers of channels already considered; and determining the optimal number of channels on the basis of the determined signal qualities.
