<p>PCT No. PCT/FI92/00254 Sec. 371 Date Jun. 3, 1993 Sec. 102(e) Date Jun. 3, 1993 PCT Filed Sep. 24, 1992 PCT Pub. No. WO93/07725 PCT Pub. Date Apr. 15, 1993.The invention relates to a radio channel allocation method for a radio system in which a mobile exchange (MX) dynamically allocates radio channels to the base stations (BS1, BS2, BS3) from a predetermined pool of radio channels on a call-by-call basis. In the method according to the invention, when any of the fixed stations (BS1, BS2, BS3) detects a line failure in the transmission line between the fixed station and the control centre (MX), the fixed station starts to use only specific fallback radio channels assigned to it in advance from said pool of radio channels; and when the control centre (MX) detects a line failure in the transmission line between the control centre and any of the fixed stations (BS1, BS2, BS3), the control centre removes specific fallback radio channels assigned in advance to the particular fixed station from the pool of radio channels available to the neighbouring fixed stations of the particular fixed station.
