Mobile radio station and communication parameter control method thereof |
摘要 |
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 reaches the mobile radio station. |
