Zusammenfassung:	PROBLEM TO BE SOLVED: To converge a start procedure of an access of a random access channel (RACH) in a short time. SOLUTION: A transmission power initial value of a preamble signal is updated to an aptitude value to which a latest electric wave environment is reflected, when the electric wave environment in a mobile communication terminal has changed.
