Abstract: A telecommunication system includes a number of radio base stations connected to a telephone network, the base stations forming a link to the network for a number of cordless telephones. Each base station determines in which of a number of predetermined signal strength bands the signal strength of a signal produced by a cordless telephone and received by the base station lies. If the received signal strength lies in a lower band, the base station stores an indication of the signal, and scans through the communication channels available between the base station and the cordless telephones to determine whether a new incoming signal lies in the highest signal band, or whether by increasing the rank of the band of a stored signal, the highest signal band is reached.
