The Research and Implementation of LTE System with Automatic Neighbor Relations(ANR) in Intra-frequency neighbour cell

Min Zuguang;Li Yong;Wuhan Research Institute of Posts and Telecommunications;  
Automatic neighbor relation(ANR)function is the key technologyof LTE system in the 3GPPprotocol,and this function plays an irreplaceable role in cutting down the workload of network optimization engineer,reducing the costs of operation and maintenance and in some other aspects.The user equipment(UE)with ANR function can measure the surroundingcell environment,and according to the measurement report,eNB can update the NRT fast and efficientlywith the limit of system reference threshold,so it can ensure the handover efficiency of UE.The experimental results show that ANR algorithm can run network planning and optimization and maintenance workload while remission,without damaging service performance communication system compared to a fixed NRT.
