Aiming at the instability of the communication link caused by mobile handoff in millimeter wave cellular networks, a dual base station macro diversity scheme is proposed, and the handoff probability of the mobile user is analyzed based on the scheme. First, the mobile model of cellular users under the dual base station macro diversity scheme is established based on the hypothesis that the distribution of base stations is the Poisson point process and that the typical user adopts the nearest base station access criteria. Second, the theoretical expression for handoff probability for mobile users is derived by stochastic geometry theory. Finally, the theoretical solution of handoff probability is solved by the MATLAB simulation software, and the reliability of the analytical results is verified by the Monte Carlo simulation. Simulation results show that with the increase of the mobile speed and base station density, the probability of one handoff increases obviously, but the probability of two handoffs is almost unchanged. Therefore, the proposed scheme can better guarantee the stability of the mobile user’s communication link.
