A line control method is applied to a mobile communication system in which a mobile station communicates with one of a plurality of base stations which are installed within the same zone via a speech channel of the one base station, where the base stations have a common control channel. The line control method includes the steps of (a) storing timing information which indicates access timings of the mobile station with respect to each of the base stations and is received via the control channel, and (b) receiving control information which indicates a result of allocation of free speech channels in an arbitrary base station with respect to each call based on a predetermined call processing procedure of the arbitrary base station via the control channel, and switching the access timing of the mobile station from an access timing with respect to the arbitrary base station to an access timing with respect to one of the base stations other than the arbitrary base station and stored in the step (a), so that the mobile station communicates with the one of the base stations via a speech channel which is determined by the control information.
