Effect of user mobility on soft handoff performance in cellular communication
Yali Qin, Xibing Xu, Ming Zhao, Yan Yao · 2002
The handoff rate is a fundamental index to evaluate the handoff performance and as a result it affects the overall performance of a cellular mobile communication system. Meanwhile, moving patterns of mobiles are critical to the handoff rate. In this paper the effect of user's mobility on system handoff rate is studied The analytic result shows that the soft handoff rate increases with the mobile speed linearly, which is confirmed by the simulation results. Based on it, the effect of the combinations of users' multiple velocities on the handoff rate is investigated. It turns out that the handoff rate of a system with several user mobility patterns can be estimated with the handoff rates of corresponding single user mobility pattern systems.
