Abstract: In a monitoring region including multiple cells, UE reports KPI parameters and location information to an eNodeB when triggering an A3 event representing that QoS of a neighboring cell is better than a predefined offset of a serving cell. The eNodeB reports the KPI parameters and the location information to an OAM device in each monitoring cycle. The OAM device classifies UEs according to the KPI parameters and a cluster analysis method, and determines according to a cluster analysis result whether there is a disconnected cell in the monitoring region; when determining that there is a disconnected cell in the monitoring region, counts the number of disconnected cells, determines disconnection types of the disconnected cells, locates the disconnected cells according to the location information of the UEs in the SON, and triggers a compensation measurement for each disconnected cell according to the disconnection type of the disconnected cell.
