The access scheme is required to have fast access and reliable transmission in satellite communications because of the long propagation delay and different channel characteristics. In this paper we propose a hybrid access scheme based on one phase preamble and channel monitoring/allocation for satellite communications. For fast access, we use an access scheme of 3GPP2 using one phase preamble instead of 3GPP using two phase preambles, and for more reliable transmission, the CM/CA scheme of 3GPP is applied. We investigate the performance of these proposed schemes through simulation. According to the simulation results, we could improve the random access scheme and could support smaller delay in satellite environments.
