Abstract:
A control method of a portable radio unit for use in a mobile system comprising the steps of:(a) measuring a reception intensity of control information by a reception intensity detector; (b) performing a time-sequential linear-predictive analysis on said measured reception intensity by a linear prediction analyzer; (c) predicting a reception intensity at a next time; (d) setting a receiving interval of the control information on the basis of said predicted reception intensity; (e) measuring the reception intensity of said control information on the basis of said set receiving interval; (f) decimating said measured reception intensity on the basis of a receiving interval set by an intermittent receiving interval updater; and (g) repeating said series of operations (a) through (f), thereby reducing an electric power consumption of a battery in a wait standby mode.
