A method of channel allocation in a cellular communication network wherein
a radio channel is to be selected for establishment of a connection in an
environment with potentially interfering signals, the method comprising:
establishing a radio channel candidate; processing the radio channel
candidate with potentially interfering signals and calculating a carrier
to interference ratio (CIR) for the selected carrier frequency of the
radio channel candidate and the potentially interfering signals;
calculating a dominant interference ratio (DIR) being the ratio of the
strongest potentially interfering signal with respect to the other
potentially interfering signals; and using criteria based on at least one
of the dominant interference ratio and the carrier to interference ratio
in a selection process for selecting a channel for the connection to be
established.
