Abstract:
1. A mobile communication system comprising: a plurality of base stations; a mobile terminal; and a base station controller, wherein: said base station controller establishes a communication channel between said mobile terminal and a first one of said plurality of base stations; said base station controller determines a first bit error rate and a first signal to noise ratio, calculates a first velocity of said mobile terminal from the first bit error rate and first signal to noise ratio, selects a second one of said base stations based on the first velocity of said mobile terminal, and establishes a communication channel between said mobile terminal and said second one of said base stations; and said base station controller measures a second bit error rate and a second signal to noise ratio, calculates a second velocity of said mobile terminal based on the second bit error rate and second signal to noise ratio, and based on the second velocity of said mobile terminal, reestablishes the communication channel between said mobile terminal and said first one of said base stations.
