RADIO SYSTEM, RADIO NODE DEVICE, AND PATH CONTROL DEVICE

摘要

Disclosed is a technology for a radio system, a radio node device, and a path control device which can reconfigure a path corresponding to fluctuation of a bandwidth originating from a change in the transmission environment of a radio link. According to the technology, an arbitrary radio node device in a plurality of radio node devices 200a to 200f detects the transmission state of a radio link linked to the radio node device, changes the modulation method of the radio link based on the detected transmission state of the radio link, transmits information indicating the changed modulation method and the number of paths using the radio link whose modulation method is changed to a path control device 103, and a path control device 103 detects a path which requires route changing based on the transmitted information indicating the modulation method and the number of paths using the radio link whose modulation method is changed, and decides a new path from the states of the overall radio links.
