Abstract

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 A3 Event from the handover failure rate. Then ,we propose a new handover algorithm which can reduce the pingpang handover compared to A3 algorithm.
