Abstract
A radio communication apparatus which can cope with a plurality of different communication systems automatically selects a communication system exhibiting good communication channel quality from the plurality of communication systems, thereby performing communication. Communication channel qualities are compared with each other on the basis of at least one of a reception signal electric field strength, a reception data quality signal, and a reception data error rate which are received from each radio base station, or upon assigning priorities thereto, thereby determining a communication system.
