1. A method by which a radio receiver may indentify the base station related thereto in a radio communication system which shares a signaling channel with the base station of at least one other communications system, such method comprising: transmission by each base station of synchronizing signal bursts at time intervals determined in accordance with a predetermined sequence which is different for each base station, each signal burst including an indication of the time interval between transmission thereof and a succeeding signal burst to be transmitted by such base station; reception of such signal bursts by said receiver; comparison in said receiver of the time intervals between reception of sequential signal bursts with a predetermined sequence of time intervals internally stored therein; and synchronization of said receiver with its related base station by matching the time intervals between reception of such sequential signal bursts with the predetermined sequence of time intervals internally stored in said receiver.
