PROBLEM TO BE SOLVED: To smoothly transmit and share information by coordinating two radio systems different in radio modulation systems, frequency band widths, and transmission rates. SOLUTION: When a radio system cooperation apparatus (EQ) coordinating a TDMA radio system and an FDMA radio system different from each other in communication speeds receives a data signal transmitted from a radio terminal (BMti) of the TDMA radio system to a radio terminal (BMfi) of the FDMA radio system, the apparatus (EQ) synchronizes a plurality of carriers in the FDMA radio system and converts a communication speed of the data signal transmitted from the TDMA radio system into a data signal of the FDMA radio system and divides the converted data signal into a plurality of carriers and transmits them to the radio terminal of the FDMA radio system, whereby both systems can cooperate with each other.
