Abstract: The calling of users is very uneven and the channel collision detection ability is quite weak in Low Earth Orbit(LEO) satellite communication. To ensure quality of service, a novel Load Measurement Access Control(LMAC) protocol is proposed. The effect which the waiting probability of calling service, calling number and measure parameter on the performance of the networks are analyzed. Simulation experimental results show that the proposed access protocol is appropriate, and the LMAC protocol can simplify the description of special service.
