PURPOSE:To prevent a collision of a wireless signal caused by one-way and two-way transmissions, by operating a transmission signal holding means of a bidirectional wireless terminal equipment by using a busy signal from a satellite terminal equipment. CONSTITUTION:When a transmitting signal of an up-ring signal A is transmitted to a satellite terminal equipment 7 from a one directional wireless terminal equipment 8, a busy signal B by a down-ring signal is transmitted to a bidirectional wireless terminal equipment 9 from the terminal equipment 7. When this busy signal B is received, the terminal equipment 9 reserves a transmission to the terminal equipment 7 by its transmitting signal holding means. Also, when the transmitting signal is transmitted to the terminal equipment 7 from the terminal equipment 9, the terminal equipment 7 transmits the busy signal in the same way. |
