Title:
RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3947370
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a radio communication system that can avoid or relax a compressed band by a hello packet.
SOLUTION: The system transmits only own station information as the hello packet as a rule (204, 206). When a participation station is detected (220) on the basis of the hello packet received from another station and information on a database 212 in its own station or a retire station is detected, the hello packet including adjacent station information is transmitted (210, 214, 204). When all adjacent station information including all participation stations and retire stations detected by its own station has been received between preceding transmission of the hello packet and the present is received by the hello packet from another station (230), difference information with respect to all the adjacent station information is generated (232). When a first hello packet is transmitted after detection of participation and retire stations and the difference information is generated after the preceding transmission (208), the hello packet including the difference information is sent (210, 206), and when not transmitted, the hello packet including all the adjacent station information is sent (214, 206).
