Abstract: Abstract This paper firstly analyzes the handover mechanism of vehicle-mounted base station technology in high speed railway system, and finds that the communication interruption of the physical layer will last for a period of time although the switch of MAC layer has been completed. In order to solve this problem, an improved switch mechanism is proposed in this paper in order to ensure the continuality of communication. Then the data transmission rule between RAUs and the train will be discussed through using queue theory. The original mechanism and the improved mechanism are modeled as the loss Geom/G/1 system with interruptions and vacation respectively. And the analytical equations of the loss rate and the waiting delay are deduced. Then, the numerical simulations of the two mechanisms are discussed and the relationship between the packet loss rate, the waiting delay, and the other parameters is obtained respectively. At the same time, the performance of the two mechanisms are compared by setting the same parameter values in order to verify the superiority of the proposed mechanism and its greatest advantage, that is, the improved mechanism can be compatible with all handover mechanisms.
