RELAY APPARATUS, RELAY METHOD, AND RELAY PROGRAM

摘要

A relay apparatus 1 includes: a priority table 14 for storing a higher priority transmission identifier and transmission condition data; a bandwidth management part 12 for determining whether or not a received transmission identifier should be recorded in the priority table 14 as a higher priority transmission identifier; a priority control part 16 for relaying the transmission identified by the higher priority transmission identifier by priority; a monitoring part 11 for monitoring a transmission condition of the wireless terminals 2 a , 2 b and storing a value indicating a degree of degradation of the transmission condition as transmission condition data in the priority table 14 ; and a lower priority transmission identifying part 15 for selecting a transmission with a higher degree of degradation of a transmission condition as a lower priority transmission in the case where a total bandwidth in use for transmissions indicated by the higher priority transmission identifiers exceeds a predetermined threshold value. The priority control part 16 relays the transmissions other than the lower priority transmission, by priority compared with the lower priority transmission. This makes it possible to stably and efficiently utilize a limited bandwidth available for a transmission between a relay apparatus and a wireless terminal.
