Nowadays, satellite networks (SATNETs) will serve important role to integrate the terrestrial infrastructures. Since the SATNETs have inherent long time delay, it is needed to reduce the latency to be served properly. Even in a mesh topology, it takes two hops to establish a direct link between two satellite terminals (STs) at initialization. In this paper, we propose a novel multiple access scheme to reduce the time delay, using control channels in SATNETs along with the virtual allocation and the frequency mirroring property. Through numerical analysis, we investigated the expected delay to send a packet among terminals. The results showed that using control channel to make a direct link is feasible for SATNETs.
