摘要： A method and apparatus for judging type of a handover failure. The method includes: judging type of a handover failure, by a base station of a serving cell where UE is present before a connection failure occurs, according to related information and a maximum measurement result of a downlink signal measured by the UE at the serving cell. The type of a handover failure in a heterogeneous network may be accurately judged by taking the maximum measurement result of the downlink signal of the serving cell into account, thereby enabling the network side to adjust a handover parameter based on the judgment result of the type of the handover failure, so as to ensure the performance of the network.
