N2 - Most researches on multiplexing in advanced orbiting systems (AOS) were made by simulation, and few literatures got theoretical results. The packet time delay of polling-based multiplexing in AOS was studied. Mathematical model was established by using vacation queue system with non-exhaustive service, and it was analyzed through cycle regeneration method. A calculation formula of multiplexing packet time delay was derived, and the lower bound value was also obtained. Simulation results show that when the packet arrival rates are 1, 2, 3 packets per second and downlink rate ranges from 240 to 330 bit/s, simulation values of packet time delay are larger than the theoretical lower bound values, which proves the correctness of theoretical derivation. The results can provide reference for practical engineering design.
