PCT No. PCT/FI94/00389 Sec. 371 Date May 2, 1995 Sec. 102(e) Date May 2, 1995 PCT Filed Sep. 2, 1994 PCT Pub. No. WO95/07011 PCT Pub. Date Mar. 9, 1995A method for selecting a channel and a base station in a mobile radio system, the geographical coverage area of which is divided into radio cells, each radio cell including a main base station indicated by an identifier, and at least one of the radio cells including at least one infill base station. In the method, the main base station signals with subscriber stations on a control channel having a downlink frequency for signalling from a base station to a subscriber station and an uplink frequency for signalling from a subscriber station to a base station. Each infill base station monitors the subscriber stations at the uplink frequency of the control channel of the respective main base station. To select the best possible main base station, each infill base station measures the quality of the control channels of predetermined ones of the main base stations and selects, on the basis of the quality of the downlink frequencies of the control channels, a main base station the uplink frequency of the control channel of which it begins to monitor.
