MOBILE RADIO STATION AND COMMUNICATION PARAMETER CONTROL METHOD THEREOF
First Claim
1. A mobile radio station communicating with an opposite radio station based on a communication parameter preliminarily set, the mobile radio station comprising:
- speed detection means for detecting a moving speed of the own apparatus based on information acquired via a satellite navigation system and/or information acquired from at least one base station; and
control means for varying the communication parameter according to the moving speed detected by the speed detection means.

Abstract
There is provided a mobile radio station and a communication parameter control method thereof capable of shortening a time period required for speed detection and thereby controlling a communication parameter quickly and with little power. A mobile radio station performing communication based on a communication parameter preliminarily set includes a positioning unit measuring a position of the own apparatus based on information acquired via GPS and/or information acquired from at least one base station, a speed detection unit detecting a moving speed of the own apparatus based on positions measured at different times, and a parameter selection function unit varying the communication parameter according to the moving speed detected. The positioning unit may calculate a distance from the base station to the mobile radio station based on a time period from when a signal is sent from the base station to when the signal reached the mobile radio station.
