<p>PROBLEM TO BE SOLVED: To establish the synchronization of an overall system by allowing each base station to take synchronization independently, without giving interferences and disturbances to surrounding base stations. SOLUTION: When a base station (CS-m) is started in a state where a prescribed base station (CS-n) sends a notice signal (2-1) in a prescribed timing, first the station (CS-m) receives a notice signal (2-2) from surrounding base stations. Upon the receipt of the notice signal (2-1) from the base station (CS-n), the base station (CS-m) calculates a difference (m-n) between a received specific number (n) of the base station (CS-n) and a specific number (m) of its own station, recognizes a transmission timing deviated by a time equivalent to (m-n) from the transmission timing of the base station (CS-n) as a timing of information notice of its own station and transmits a notice signal (2-3). When a base station (CS-m') is started thereafter, the base station (CS-m') receives the notice signal (2-1) from the base station (CS-n) or a notice signal (2-3) from the base station (CS-m), to execute a similar operation, thereby deciding the transmission timing of its own station. Thus, the synchronization of the entire system is established.</p> |
