load balancing conflict avoidance long term evolutions average network throughput call dropping ratio call blocking ratio radio link failure ratio
To solve the conflict about load balance(LB)in long term evolution(LTE)systems,an optimal method of conflict avoidance is proposed here.This method solves the conflict not only by changing the cell specific offset but also by considering the user speed.The cell specific offset and the time-to-trigger are coordinated,so that the handover range of LB is dynamically adjusted,and the conflict is solved.The numerical simulation results show that the proposed method can raise the average network throughput to not more than 15 Mbit/s and reduce the call dropping ratio to not more than 15%,and the call blocking ratio and the radio link failure ratio are decreased obviously.
