RADIO COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To provide a radio communication system in which only one set of communication terminal is needed when a communication system used by transmitting and receiving is different, and audio data which is not needed in a communication is not sent to a LAN. SOLUTION: In the radio communication system, a management terminal 4 is set to function only for transmitting one kind (HF-A1) of a radio software according to the selection by the selecting screen of the communication terminal 3-1. Since one kind (HF-A2) of other radio software can be set to function only for receiving the one kind (HF-A2) of other radio software. Accordingly, when the transmitting and the receiving are also made by a distinct radio system, they are performed from the same communication terminal 3-1. Moreover, unwanted audio data, namely, neither the voice data from the software radio unit 1-1 nor the voice data to the software radio unit 1-2 is sent to the LAN 5. COPYRIGHT: (C)2006,JPO&NCIPI
