<p>PURPOSE:To eliminate the need for an exclusive slot for slot control by sending a burst signal comprising a slot reserving signal and information to be sent, reserving the slot position in the next frame when the signal does not collide with the burst signal of other station and sending the same burst signal again when collided with each other. CONSTITUTION:When a ground station TS2 sends information, an outgoing channel signal 8 is supervised and the presence of the information A1 16 sent from the ground station TS1 at the 1st position in a frame 14 is confirmed and a burst signal B1 19 is sent at the 3rd position from the first in the idle frame 14 in each slot 15. If the burst signal B1 19 collides with the burst signal C1 20 sent from a ground station TS3, the ground stations TS2, TS3 send again burst signals B1 23, C1 22 of the same content again.</p> |
