Abstract
A mobile station (mobile communication unit) receives system software from a base station via an antenna and a transmitter/receiver, and stores the received system software in a memory. A digital signal processor in the mobile station then performs communication processing according to the system software stored in the memory. By transmitting various system software from the base station, the single mobile station can easily be adapted to different communication principles. The base station also receives system software from a center via a public exchange network, and stores the received system software in a memory. A digital signal processor in the base station then performs communication processing according to the system software stored in the memory.
