In order to reduce handover delay caused by handover failure, radio resource is reserved for handover users not only at target cell, but also at prepared cells. This has been agreed in 3GPP LTE. However, these reserved resources cannot be assigned for other users until the finishing of the handover, which results in inefficiency of radio resource utilization. This paper presents a new resource reservation scheme for handover users to achieve fast handover failure recovery and efficient radio resource utilization. By proposed scheme, a resource pool at prepared cells is shared among multiple users, and the number of prepared cells is dynamically set according to the service type of users. Numerical analysis and simulation results show that the proposed scheme can improve successful handover probability and reduce handover delay. |
