RADIO DATA COMMUNICATION SYSTEM AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a radio data communication system for voice speech and non-voice data communication where the telephone number of a non-voice data communication terminal receiving non-voice data such as video image data and picture data signals through radio communication is used in common with the telephone number of a terminal for voice speech, and the voice speech terminal and the non-voice data communication terminal are provided independently and they are added as required. SOLUTION: A mobile station 20 is equipped with an extension communication function, which converts signals such as non-voice data received by the mobile station into extension signals and transmits/receives the extension signals with relay to/from other terminals such as a personal computer 10 including a display means and a keyboard. The system is provided, when necessary, with other terminals such as a display extension terminal 21 that displays video images and pictures received from a radio channel and transmission data input means 33, 34 that transmit non-voice data through a radio channel as extension terminals separately and independently from the mobile station.
