A data relay system includes: a master that functions as a master station of TDMA; slaves that function as slave stations of the TDMA; and REPs that relay communication between the master and the slaves, function as slave stations in a higher-level TDMA system, and function as master stations in lower-level TDMA systems. The master allocates, as a statically allocated time, an operating time once to each of the TDMA systems, sets, as a dynamically allocated time, a time obtained by excluding the statically allocated time from an allocated period, and allocates, based on communication states in the statically allocated time, the dynamically allocated time as operating times of the lower-level TDMA systems.
