In one-dimensional mobile cellular networks such as arterial roads or speedways, blocking rate of call increases according to the increase of new call arrival rate. If there is only one available channel and if we do not distinguish between new call and handover call, then it is arbitrary which new call or handover call can use the available channel and starts communication. Moreover, if some call uses a channel in the long time and keeps long communication, then there would not be available channels for new arrival or handover calls. If we assign the priority of channel usage to calls, then there is possibility that all calls can not use channel fairly. In this paper, we introduce channel assignment strategy and evaluate this strategy by simulation. This strategy is that if there is a new arrival or handover call and if some call uses a channel in the long time, then this long call is quitted and the channel that is used in the long time by the call is assigned to the new arrival or handover call.
