Abstract:
This paper provides a new perspective for IP mobility support in LEO satellite network, that the network mobility should be solved via network driving rather than terminal driving methods. Terminal driving methods comes from terrestrial network which ones are typically reactive to the moving of users and improve the predictability of the terminals’ motion behaviors to enhance the performance. However, the mobility in LEO satellite network most comes from network(satellites) rather than terminals. It is inefficient to solve the continuous, high-speed, global and regular network mobility via terminal driving solutions who are designed for intermittent, low-speed, local and irregular user mobility. After modeling the satellite mobility behavior for single and multiple orbit plane, a network driving mobility management solution, namely NDM, is proposed in this paper, including 1) trigger and selection 2) proxy group handover 3) silent and explicit resource release. NDM utilizes the benefit of network driving and cooperate with terminal driving methods for robust consideration. Evaluations are conducted to proof the feasibility of mechanism to improve performance and apportion cost.
