Handover (HO) is one of the key procedures, which ensures user equipment (UE) moving smoothly in long term evolution (LTE) systems. Generally, hard handover has a high outage probability and is relatively simple, but when the velocity of UE is high, the procedure may be unreliable, especially for VoIP service. In the special scenario high-speed railway, network deployment is known and an optimized...
One of the main goals of LTE is to provide seamless access to voice and multimedia services with strict delay requirements, which is achieved by supporting effective handover algorithm from source cell to target cell. In this paper we first give an overview of the LTE architecture and the LTE intra-frequency handover procedure. Secondly, we analysis the performance of A3 handover algorithm based on...
