To solve low success rate of handover caused by spurious emission interference in TD-LTE system, this article analyzes problem positioning process,investigation and confirmation process of spurious emission interference by handover success rate index,procedure,origin of spurious emission interference and its feature. It also provides solutions to eliminate or avoid spurious emission interference.With actual engineering case,the solution proves that avoiding interference has evident effects on quick positioning and eliminating low success rate of handover caused by spurious emission interference.
