There are many criteria for managing the priority in calling queues. The purpose of our work is to make a balance between two conflicting requirements: maximize the resource utilization and minimize the forced handover call dropping rate. This balance can be satisfied by using the dynamically manages of the priority criterion which is changed according to the current status of the hand off queue(remaining
time(Tr) and rate of change of RSS (ΔRSS)). The result is clear for reducing the blocking probability within range from 2% to 50%.
