While the technologies of spot beam and frequency reuse in high-throughput satellite communication system can greatly improve the system capacity,the problem of handoff should also be solved with vehicular and airborne and shipborne terminal users moving among different beams.In order to test handoff strategies of mobile users in the indoor environment,a testing environment is built based on the characteristics of satellite channels,simulating the scenario in which mobile users move across different beams in the overlapping area covered with multiple beams.The testing results show that the handoff scenario can be effectively built through this method,solving the testing problem.
