The beam-hopping technology can solve the problems of uneven user
distribution and uneven service demand, and improve the efficiency of
resource utilization. It is one of the important technologies of future
satellite-ground integrated communication. However, the mobility of LEO
satellites and the on-demand scheduling of beams make each satellite
beam correspond to multiple ground wave positions, which brings great
difficulties to data processing. In this paper, after analyzing the
difficulties of the data forwarding buffer of the beam-hopping system, a
double-linked list structure of user state chain and data buffer chain
is proposed, which solves the problem of data forwarding between the
satellite and users in the dynamic state, and provides an efficient
solution for the data exchange of the beam-hopping LEO satellite.
