Abstract
In a base station of a wireless telecommunications system for communicating with mobile terminals, a radiowave is received on a transmission channel and compared in field intensity with a threshold value. The threshold value is considered to be received while unused, in view of the receiver characteristics of the base station, and the base station selects a channel with the field intensity below the threshold value as an idle channel to form an idle channel list. To communicate with a mobile terminal, a channel is selected at random among the channels listed in the idle channel list. This makes it possible to reduce the probability that the same channel as that of a contiguous base station, will be selected and enables the channel selection to be achieved quickly and positively in the base station of the wireless telecommunications system sharing transmission channels of the same frequency band as that of contiguous base stations.
