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.

Claims

1. A radio communication apparatus comprising:

radio wave signal communication means for receiving from and transmitting a radio wave signal to a base station;

communication means for providing communication to an operator through said radio wave signal receiving and transmission means;

speed detecting means for detecting a speed of said radio communication apparatus to said base station from an output of said radio wave signal communication means;

comparing means for comparing the detected speed with a reference; and

control means responsive to said comparing means for controlling said communication means when the detected speed exceeds said reference,

wherein said communication means comprises call detection means for detecting a call from said base station and sound processing means including first amplifying means for receiving and amplifying a first sound from an operator with a first gain and second amplifying means for amplifying a sound signal from said base station with a second gain, wherein said control means increases first and second gains to provide a hands-free communication to said operator in response to the detected call when the detected speed exceeds said reference.

2. A radio communication apparatus comprising:

radio wave signal communication means for receiving from and transmitting a radio wave signal to a base station;

communication means for providing communication to an operator through said radio wave signal receiving and transmission means;

speed detecting means for detecting a speed of said radio communication apparatus to said base station from an output of said radio wave signal communication means;

comparing means for comparing the detected speed with a reference; and

control means responsive to said comparing means for controlling said communication means when the detected speed exceeds said reference,

wherein said communication means comprises call detection means for detecting a call from said base station, storing means, telephone number data detection means for detecting telephone number data from the reception radio wave signal, one-touch dialing means having a one-touch dial key, wherein said control means operates said telephone number data detection means in response to the detected call when the detected speed exceeds said reference and stores the detected telephone number data in said storing means and in response to an operation of said one-touch dialing key, said control means operates said communication means to transmit a dialing signal using the telephone number data from said storing means.
