Title:
RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2590753
Kind Code:
B2
Abstract:
PURPOSE: To provide the radio communication system where many and unspecified radio terminal stations or subscribers of a public network can share the same speech channel to execute even the intra-group speech in the radio communication network of the full duplex system.
CONSTITUTION: In the radio communication system where a radio base station uses a common control line to assign idle speech channels to radio terminal stations which request speech, each of plural radio terminal stations generates a speaking right request signal from a generation circuit 412 to transmit it to the radio base station by radio at the time of turning-on of a speaking right request switch 37 when the absence of a reception signal is detected by a reception signal presence/absence detector 403. Each radio terminal station is provided with a display device 38 on which the speaking permission state is displayed, a speaking permission signal detector 402 which detects the speaking permission signal destined for the station itself, and a control means which displays the speaking permission state on the display device and makes a transmission part operatable at the time of detecting the speaking permission signal.
