RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION EQUIPMENT AND MULTIPLE ADDRESS TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system that can make multiple address transmission only when a communication path up to an object radio communication equipment is established and places no limit onto the number of terminals for multiple address transmission without the need for periodic exchange of information of surrounding terminals is advance. SOLUTION: In the case of starting multiple address transmission, a radio communication equipment 11a of a transmission source transmits an auxiliary message packet. In the case that an acknowledgement message packet is sent from a destination radio communication equipment 11d, the radio communication equipment 11a regards the communication path up to the destination radio communication equipment 11d as being established to transmit a multiple address transmission data packet including data of multiple address transmission. Radio communication equipments 11b, 11c conduct multiple address transmission of the multiple address transmission data packet sent from the sender radio communication equipment 11a on the basis of type information of the multiple address transmission data acquired at the reception of the acknowledgement message packet.
