Handoff of Satellite Network for High-Speed Mobile Terminals Based on Edge Computing

摘要

The Satellite-Terrestrial Integrated Network (STIN) is a new network structure that can adapt to various services. In this kind of network, the low orbit satellites could bring more comprehensive services to fast mobile terminals, and the services needed by fast mobile terminals often switch between multiple satellites. Hence, the service handoff problem of low orbit satellites has become a key point in the satellite-terrestrial integrated network. Recent years, the emergence of Mobile Edge Computing (MEC) provides a new mode for efficient data processing with low latency for users. In this paper, we proposed an access and handoff strategy based on terminal trajectory on Satellite Mobile Edge Computing (SMEC). We obtained the trajectory information of mobile terminals in advance to obtain the handoff strategy with better performance, and carried on the preliminary simulation to verify the feasibility of this strategy.
