ab: Summary: Based on the characteristics of guaranteed handover (GH)
    algorithm, the finite capacity in one system makes the blocking
    probability (PB) of GH algorithm increase rapidly in the case of high
    traffic load. So, when large amounts of multimedia services are
    transmitted via a single low earth orbit (LEO) satellite system, the PB
    of it is much higher. In order to solve the problem, a novel handover
    scheme defined by multi-tier optimal layer selection is proposed. The
    scheme sufficiently takes into account the characteristics of
    double-tier satellite network, which is constituted by LEO satellites
    combined with medium earth orbit (MEO) satellites, and the multimedia
    transmitted by such network, so it can augment this systematic capacity
    and effectively reduces the traffic load in the LEO which performs GH
    algorithm. The detailed processes are also presented. The simulation
    and numerical results show that the approach integrated with GH
    algorithm achieves a significant improvement in the PB and
    practicability, as compared to the single LEO layer network.
