Abstract
A radio communication apparatus has a radio wave signal communication circuit and a speed detection circuit for detecting a speed of the radio communication apparatus relative to the base station from an output of the radio wave signal communication circuit. Various operations for security such as neglecting arrival of a call when the vehicle carrying the radio communication apparatus is in a high speed condition are selectively executed in accordance with the detected speed signal. A method of communicating with a base station with various operations mentioned above is also disclosed.
