The process of changing the channel associated with the
current connection while a call is in progress is under consideration. The
estimation of dropping rate in handover process of a one dimensional traffic
system is discussed. To reduce the sample size of simulation, dropping calls at
base station is considered as rare event and simulated with importance sampling
- one of rare event simulation approaches. The simulation results suggest the
sample size can be tremendously reduced by using importance sampling.
