PROBLEM TO BE SOLVED: To simplify changeover of a communication system by the user in the case that the user receives, e.g. plural communication services with different communication systems. SOLUTION: In the mobile communication system, a voice received from a microphone 1 is sent from an antenna T1 by a radio wave via a base band processing section 3 and a transmission circuit 6 or the like configuring a communication means, and a signal received from the antenna T1 is outputted from a speaker 2 via a reception circuit 7 or the like and the base band processing section 3. A control program or the like specifying plural kinds of communication systems is stored in memories 17, 18 of the base band processing section 3 and a CPU 19 configuring the communication control means sets a control program corresponding to a communication system selected by, e.g. key entry, and the radio communication is executed by the communication system. Furthermore, a base band processing section 3 storing a control program corresponding to different kinds of communication systems is built in, e.g. each of plural external modules respectively and an external module is attached to/detached from the mobile communication equipment main body to select the communication system. |
